Background: The current COVID-19 pandemic and the previous SARS/MERS outbreaks of 2003 and 2012 have resulted in a series of major global public health crises. We argue that in the interest of developing effective and safe vaccines and drugs and to better understand coronaviruses and associated disease mechenisms it is necessary to integrate the large and exponentially growing body of heterogeneous coronavirus data. Ontologies play an important role in standard-based knowledge and data representation, integration, sharing, and analysis. Accordingly, we initiated the development of the community-based Coronavirus Infectious Disease Ontology (CIDO) in early 2020., Results: As an Open Biomedical Ontology (OBO) library ontology, CIDO is open source and interoperable with other existing OBO ontologies. CIDO is aligned with the Basic Formal Ontology and Viral Infectious Disease Ontology. CIDO has imported terms from over 30 OBO ontologies. For example, CIDO imports all SARS-CoV-2 protein terms from the Protein Ontology, COVID-19-related phenotype terms from the Human Phenotype Ontology, and over 100 COVID-19 terms for vaccines (both authorized and in clinical trial) from the Vaccine Ontology. CIDO systematically represents variants of SARS-CoV-2 viruses and over 300 amino acid substitutions therein, along with over 300 diagnostic kits and methods. CIDO also describes hundreds of host-coronavirus protein-protein interactions (PPIs) and the drugs that target proteins in these PPIs. CIDO has been used to model COVID-19 related phenomena in areas such as epidemiology. The scope of CIDO was evaluated by visual analysis supported by a summarization network method. CIDO has been used in various applications such as term standardization, inference, natural language processing (NLP) and clinical data integration. We have applied the amino acid variant knowledge present in CIDO to analyze differences between SARS-CoV-2 Delta and Omicron variants. CIDO's integrative host-coronavirus PPIs and drug-target knowledge has also been used to support drug repurposing for COVID-19 treatment., Conclusion: CIDO represents entities and relations in the domain of coronavirus diseases with a special focus on COVID-19. It supports shared knowledge representation, data and metadata standardization and integration, and has been used in a range of applications., (© 2022. The Author(s).)

Phaeocystis globosa is a marine-bloom-forming haptophyte with a polymorphic life cycle alternating between free-living cells and a colonial morphotype, that produces high biomass and impacts ecological structure and function. The mechanisms of P. globosa bloom formation have been extensively studied, and various environmental factors are believed to trigger these events. However, little is known about the intrinsic biological processes that drive the bloom process, and the mechanisms underlying P. globosa bloom formation remain enigmatic. Here, we investigated a P. globosa bloom occurring along the Chinese coast and compared the proteomes of in situ P. globosa colonies from bloom and dissipation phases using a tandem mass tag (TMT)-based quantitative proteomic approach. Among the 5540 proteins identified, 191 and 109 proteins displayed higher abundances in the bloom and dissipation phases, respectively. The levels of proteins involved in photosynthesis, pigment metabolism, nitrogen metabolism, and matrix substrate biosynthesis were distinctly different between these two phases. Ambient nitrate is a key trigger of P. globosa bloom formation, while the enhanced light harvest and multiple inorganic carbon-concentrating mechanisms support the prosperousness of colonies in the bloom phase. Additionally, colonies in the bloom phase have greater carbon fixation potential, with more carbon and energy being fixed and flowing toward the colonial matrix biosynthesis. Our study revealed the key biological processes underlying P. globosa blooms and provides new insights into the mechanisms behind bloom formation.

Over 150 refractory high-entropy alloys (RHEAs) have been proposed in the last decade. Early alloys such as MoNbTaW and MoNbTaVW still show an unparalleled yield strength of approximately 400 MPa at 1600°C. However, RHEAs with even elevated high-temperature strength are necessary in aerospace vehicles and nuclear reactors to cope with advanced technology in the future. Here, solid-solution strengthening calculation and melting point prediction are combined to design single-phase RHEA for attaining ultrahigh strength at 1600°C. The results show that Hf 0.5 MoNbTaW and HfMoNbTaW alloys after fully homogeneous treatment at 2100°C for 2 h reveal a homogenous body-centered cubic phase. HfMoNbTaW alloy exhibits a yield strength of 571 MPa at 1600°C, much higher than that of MoNbTaVW (477 MPa). It is found that a plateau of strength occurs from 800°C to 1200°C, which is important for raising the strength level of RHEAs at high temperatures. This strengthening mechanism is explained with the change of deformation mode from screw to edge dislocations, which contributes an edge-dislocation-induced strength. A similar alloy design strategy could be applied to develop more RHEAs with an ultrahigh strength level., Competing Interests: No potential conflict of interest was reported by the author(s)., (© 2022 The Author(s).

Objectives: Baseball players are highly susceptible to shoulder injuries due to repetitive overhead throwing. The purpose of this study was to investigate men's collegiate baseball shoulder injury rates and associated risk factors., Methods: Using the NCAA Injury Surveillance Program (ISP) database, shoulder injury data for men's baseball players was analyzed from 2009-2010 through 2013-2014. Only the most common shoulder injuries were examined, including acromioclavicular (AC) sprain, anterior dislocation, biceps tear, biceps tendinitis, SLAP (superior labrum from anterior to posterior) tear, non-SLAP labral tear, rotator cuff tear, rotator cuff tendinitis, and shoulder impingement. Statistical analysis was performed using proportion ratios (PR). Statistical significance was initially defined as p < 0.05; a post-hoc Bonferroni adjustment was applied using a p < 0.005 threshold balancing the likelihood of false positive and false negative findings., Results: Overall, 138 shoulder injuries were identified of which 51.4% occurred during practice. Rotator cuff pathology represented 45.6% of all injuries, with rotator cuff tears significantly more likely to be season-ending injuries (PR 2.5, 95% CI 1.2-5.6, p = 0.019). Pitching or throwing was the mechanism of injury in 100% of players with rotator cuff tendonitis, 87.5% of SLAP tears, 70% of players with biceps tendinitis, and 67% of players with rotator cuff tears. Biceps tendinitis (PR 3.9, 95% CI 1.2-12.5, p = 0.024) and SLAP tears (PR 6.4, 95% CI 1.6-25.0, p = 0.008) were significantly more likely to be chronic. SLAP tears were significantly more likely to be recurrent (PR 5.5, 95% CI = 1.5-20.4, p = 0.010). Being a freshman or sophomore was significantly associated with a lower proportion of biceps tendinitis (PR = 0.2, 95% CI = 0.04-0.8, p = 0.028). All anterior shoulder dislocations occurred while running the bases or sliding, and AC sprains were significantly associated with contact (PR 20.6, 95% CI = 2.5-168.7, p = 0.0048)., Conclusions: Repetitive overhead throwing in college baseball is a common cause of overuse shoulder injuries. These athletes are especially susceptible to rotator cuff pathology, which is significantly more likely to cause season-ending injuries. While we have to interpret these results in light of both adjusted and unadjusted p-values, this information signifies the importance of shoulder injury prevention strategies by physicians and trainers taking care of collegiate baseball players.

Heavy metals and pesticides (HMPs) are common contaminants due to their extensive use worldwide. Diffusive gradients in thin films (DGT) are a good method for measuring the bioavailable concentration of pollutants. This study represents the first evaluation of HMP toxicity in aquatic biota using the DGT technique in sediments. Zhelin Bay was selected as the case study site because it has been contaminated by pollutants. Nonmetric multidimensional scaling (NMS) analysis reveals that a diverse range of pollutants (V, Cr, Ni, Cu, Zn, As, Se, InHg, Mo, Cd, Sb, W, Pb, CLP, PYR) are mainly influenced by sediment characteristics. Assessment of single HMP toxicity found that the risk quotient (RQ) values for Mn, Cu, inorganic Hg (InHg), chlorpyrifos (CLP) and diuron (DIU) are significantly higher than 1, indicating that the adverse effects of these single HMPs should not be ignored. The combined toxicity of HMP mixtures based on probabilistic ecotoxicological risk assessment shows that Zhelin Bay surface sediments had a medium probability (54.6%) of toxic effects to aquatic biota., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022.

Although polyetheretherketone (PEEK) is becoming more widely used in dentistry applications, little is known about how aging will affect this material. Therefore, this study aimed to investigate the influence of an aging treatment on fracture characteristics of PEEK dental crowns. Additionally, the impact of the addition of titanium dioxide (TiO 2 ) into PEEK was examined. Two types of commercial PEEK discs were used in this study, including TiO 2 -free and 20% TiO 2 -containing PEEK. The PEEK dental crowns were fabricated and aging-treated at 134 °C and 0.2 MPa for 5 h in accordance with the ISO 13356 specification before being cemented on artificial tooth abutments. The fracture loads of all crown samples were measured under compression tests. Results demonstrated that adding TiO 2 enhanced the fracture load of PEEK crowns compared to TiO 2 -free PEEK crowns before the aging treatment. However, the aging treatment decreased the fracture load of TiO 2 -containing PEEK crowns while increasing the fracture load of TiO 2 -free PEEK crowns. The fracture morphology of TiO 2 -containing PEEK crowns revealed finer feather shapes than that of the TiO 2 -free PEEK crowns. We concluded that adding TiO 2 increased the fracture load of PEEK crowns without aging treatment. Still, the aging treatment influenced the fracture load and microscopic fracture morphology of PEEK crowns, depending on the addition of TiO 2 ., Competing Interests: The authors declare no conflicts of interest.

As a critically endangered (CR) fish species, Chinese Bahaba is a unique "Giant Panda" fish species in China and has been listed among the national first-class wildlife protection animals and China's top 10 genetic resources of aquatic products since 2021. This fish species is of high commercial value because its swim bladder is commonly used in traditional Chinese medicine. Its otoliths are the sensory organs immersed in the endolymph for maintaining its balance and hearing. However, rare information has been reported on the sound absorption structure and chambers of otoliths of such "Giant Panda" fish. The big "C" groove was found in the fish's front sagittal otolith with the crystal cluster in the back sagittal otolith, the former of which is a 3D layered structure, that is constructed by elongated prismatic crystals. Besides, there are numerous small holes and adhesion material in this 3D layered structure, where many chambers were also found, indicating that some specific sounds may be captured by this structure and these chambers may then amplify such sounds at a certain wavelength. This finding could be of great importance for protecting and conserving this critically endangered species., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Ltd.

Objective: Evaluation of sagittal pelvic tilt is significant for hip surgeons. However, the accurate measurement of pelvic sagittal inclination (PSI) is still a challenge. The objective of this study is to propose a new method for measurement of PSI from pelvic anteroposterior radiograph based on the inverse cosine function obtained from individualized pelvic model., Methods: Collecting the imaging data of 30 patients with both pelvic CT and full-length spine radiographs. Establishing pelvic model by customized 3D reconstruction software. The length of three groups of longitudinal and transverse line segments (A'p and B') were measured from full-length spine anteroposterior radiographs. The corresponding anatomical parameters, including A, B, b, ∠α, ∠γ, were measured and calculated on the same patient's pelvic model. The estimated PSI (ePSI) based on three groups of anatomical landmarks, including ePSI-1, ePSI-2, and ePSI-3, were calculated by equation, ePSI = arccos A ' p b * B ' - ∠ α , and compared with the actual PSI (aPSI) measured by Surgamap software. For the reliability and validation evaluation, three observers measured these parameters in two rounds. Intra-class correlation and inter-class correlation were both calculated. Bland-Altman method was used to evaluate the consistency between the estimated PSI (ePSI) and the actual PSI (aPSI)., Results: ePSI-1 and ePSI-2 showed excellent intra-observer reliability (0.921-0.997, p < 0.001) and inter-observer reliability (0.801-0.977, p < 0.001). ePSI-3 had a fair inter-observer reliability (0.239-0.823, p < 0.001). ePSI-1 showed the strongest correlation with aPSI (r = 0.917, p < 0.001). Mean (maximum) absolute difference of ePSI-1, ePSI-2, and ePSI-3 is 2.62° (7.42°), 4.23° (13.78°), and 7.74° (31.47°), respectively. The proportion of cases with absolute difference less than 5° in three groups were 86.7% (ePSI-1), 66.7% (ePSI-2), 56.7% (ePSI-3)., Conclusion: This new method based on inverse cosine function has good reliability and validity when used in the evaluation of PSI on pelvic anteroposterior radiographs., (© 2022 The Authors.

Objective: To evaluate the effect of autologous hematopoietic stem cell transplantation (ASCT) on minimal residual disease (MRD) in patients with multiple myeloma (MM). Method: From August 2018 to August 2021, 92 patients newly diagnosed with MM who had received either the bortezomib combined with cyclophosphamide and dexamethasone (VCD) or the bortezomib, lenalidomide and dexamethasone (VRD) induction regimens followed by sequential ASCT were assessed for overall survival (OS) and the MRD negative rate. The differences in efficacy at 100 days after transplantation were assessed according to factors, including age, risk stratification, target organ damage, and pre-transplant regimen, etc. Results: Among the 92 patients, there were 45 males and 47 females, with a median age of 57.3 (35-67) years. Fifty-seven patients received the VCD regimen, and 35 received VRD as induction regimen. Forty-three patients received busulphan combined with cyclophosphamide and etoposide (BCV), and 49 patients received high-dose melphan (HDM) regimen as pre-transplantation treatment. After transplantation, the total complete remission (CR) rate of 92 patients increased from 23.9% (22/92) to 58.7% (54/92), and the MRD negative rate increased from 4.4% (4/92) to 33.7% (31/92), and the differences were statistically significant (all P <0.05). After transplantation, the MRD negative rates of patients with PR, VGPR and ≥CR before transplantation were 17.6% (6/34), 33.3% (12/36) and 59.1% (13/22), respectively ( P =0.006). The CR rates of patients with or without plasmacytoma at initial diagnosis were 36.4% (4/11) and 65.4% (53/81), respectively ( P =0.029), and the MRD negative rates were 18.2% (2/11) and 39.5% (32/81), respectively ( P =0.037), and the differences were statistically significant. The MRD negative rates in high-risk patients and standard-risk group were 30.5% (12/28) and 42.9% (18/59), respectively ( P =0.258). For patients who achieved efficacy above VGPR before transplantation, the MRD negative rates after transplantation in VCD-induced group and VRD group were 29% (9/31) and 59.3% (16/27), respectively ( P =0.033), and in BCV group and HDM group were 24% (6/25) and 57.6% (19/33), respectively ( P =0.016), the differences between the groups were both statistically significant. Conclusion: ASCT can overcome the adverse factors such as high-risk cytogenetic abnormalities, and significantly improve the CR rate and MRD negative rate of MM patients. However, the benefit for patients with plasmacytoma at initial diagnosis is not as good as that of patients without.

Background: Hip fracture (HF) is a major challenge for healthcare systems in terms of increased costs and lengths of stay, and it has been estimated that by 2050, half of the projected 6.26 million global HFs will occur in Asia. Owing to the high morbidity and mortality associated with HF in elderly individuals, it is crucial to recognize at-risk elderly patients in the ED so that special precautions and preventive measures can be taken. While comprehensive geriatric assessment (CGA) has been shown to improve outcomes and prevent secondary fractures in elderly individuals with HF in outpatient settings, there is a lack of data to identify elderly Asian patients who are at risk of HF via using CGA in the emergency department (ED). The aim of this study is to identify the characteristics of elderly Asian patients in the ED who have an increased risk of HF via CGA., Methods: A case-control study was conducted in the ED at Taipei Veterans General Hospital, a medical center located in Taipei, Taiwan, from October 2018 to December 2019. Patients > 75 years old with and without HF were compared using data obtained from CGAs conducted by trained nurses., Results: A total of 85 HF patients (cases) and 680 non-HF patients were enrolled, among whom 340 non-HF control individuals (controls) were selected by simple random sampling. HF occurred more frequently in women and in patients with depressive symptoms. An association between decreased handgrip strength and HF risk, especially in men, was also identified ( p = 0.011). The variables independently associated with the presence of HF in the multivariate analysis were female sex (odds ratio [OR]: 2.229; 95% confidence interval [CI]: 1.332-3.728) and decreased handgrip strength (OR: 2.462; 95% CI: 1.155-5.247)., Conclusions: By performing CGAs in the ED, we found that female sex and decreased handgrip strength were associated with HF risk. Therefore, we propose that targeted assessment of handgrip strength in female patients aged > 75 years in the ED may identify those at greatest risk of HF, resulting in improved emergency care for geriatric patients., Competing Interests: This work was not supported by any company.

The emissions of vessels are higher when they sail at sea than when they are at a port, and such emissions affect air quality considerably. In this study, an activity-based method was used to calculate the quantities of various pollutants emitted by large container ships sailing at optimal speed on Far East-Europe trunk routes, which cover seven of the largest economies with high population density. We determined the emission quantities of various pollutant, such as carbon dioxide (CO 2 ), sulfide [Formula: see text]), nitride ([Formula: see text]), and particulate matter-for the newest mega container ships deployed on the aforementioned routes by THE Alliance. This study considered vessel speed as a critical variable and found that to reduce vessel emissions, port authorities should mandate that vessels reduce their speed when entering and leaving a port. Considering maritime practice, setting the optimal speed of a vessel as 15-18 knots is the most effective method for reducing emissions. On the basis of the obtained results, appropriate recommendations are made to the International Maritime Organization, international shipping companies, and port authorities., (© 2022.

Patient-derived organoids and cellular spheroids recapitulate tissue physiology with remarkable fidelity. We investigated how engagement with a reconstituted basement membrane in three dimensions (3D) supports the polarized, stress resilient tissue phenotype of mammary epithelial spheroids. Cells interacting with reconstituted basement membrane in 3D had reduced levels of total and actin-associated filamin and decreased cortical actin tension that increased plasma membrane protrusions to promote negative plasma membrane curvature and plasma membrane protein associations linked to protein secretion. By contrast, cells engaging a reconstituted basement membrane in 2D had high cortical actin tension that forced filamin unfolding and endoplasmic reticulum (ER) associations. Enhanced filamin-ER interactions increased levels of PKR-like ER kinase effectors and ER-plasma membrane contact sites that compromised calcium homeostasis and diminished cell viability. Consequently, cells with decreased cortical actin tension had reduced ER stress and survived better. Consistently, cortical actin tension in cellular spheroids regulated polarized basement membrane membrane deposition and sensitivity to exogenous stress. The findings implicate cortical actin tension-mediated filamin unfolding in ER function and underscore the importance of tissue mechanics in organoid homeostasis., (© 2022 The Authors.)

Background & Aims: Anti-granulocyte macrophage-colony stimulating factor autoantibodies (aGMAbs) are detected in patients with ileal Crohn's disease (CD). Their induction and mode of action during or before disease are not well understood. We aimed to investigate the underlying mechanisms associated with aGMAb induction, from functional orientation to recognized epitopes, for their impact on intestinal immune homeostasis and use as a predictive biomarker for complicated CD., Methods: We characterized using enzyme-linked immunosorbent assay naturally occurring aGMAbs in longitudinal serum samples from patients archived before the diagnosis of CD (n = 220) as well as from 400 healthy individuals (matched controls) as part of the US Defense Medical Surveillance System. We used biochemical, cellular, and transcriptional analysis to uncover a mechanism that governs the impaired immune balance in CD mucosa after diagnosis., Results: Neutralizing aGMAbs were found to be specific for post-translational glycosylation on granulocyte macrophage-colony stimulating factor (GM-CSF), detectable years before diagnosis, and associated with complicated CD at presentation. Glycosylation of GM-CSF was altered in patients with CD, and aGMAb affected myeloid homeostasis and promoted group 1 innate lymphoid cells. Perturbations in immune homeostasis preceded the diagnosis in the serum of patients with CD presenting with aGMAb and were detectable in the noninflamed CD mucosa., Conclusions: Anti-GMAbs predict the diagnosis of complicated CD long before the diagnosis of disease, recognize uniquely glycosylated epitopes, and impair myeloid cell and innate lymphoid cell balance associated with altered intestinal immune homeostasis., (Copyright © 2022 The Authors.

In epigenome-wide association studies (EWAS), the mixed methylation expression caused by the combination of different cell types may lead the researchers to find the false methylation site related to the phenotype of interest. To correct the EWAS false discovery, some non-reference models based on sparse principal component analysis (sparse PCA) have been proposed. These models assume that all methylation sites have the same priori probability in each PC load. However, it is known that there already has gene network structure corresponding to the methylation site. How to integrate this genome network knowledge into the sparse PCA models to enhance the performance of existing models is an open research problem. We introduce GN-ReFAEWAS, a non-reference analysis model which integrates the prior gene network structure into the PCA framework to control the false discovery in EWAS. We used one simulated data set, three real data sets, and three additional tests for experiments and compared with four existing models. Experimental results show that the GN-ReFAEWAS model is better than the existing model by 2-90% in the indicators of sensitivity, specificity, genomic control factor λ, and correlation coefficient factor cov with known cell phenotype ratio., (© 2022.

Background: Remifentanil is a rapid onset and rapid recovery opioid. The combination of remifentanil and propofol for deep sedation decreases the incidents of movement, cough, and hiccup. We evaluated the efficacy and safety of remifentanil during endoscopic ultrasound-guided tissue acquisition., Methods: We retrospectively reviewed patients in whom endoscopic ultrasound-guided tissue acquisition was performed for solid mass lesions of the upper gastrointestinal tract and adjacent organs. All patients were premedicated with midazolam (2 mg), and target-controlled infusion of propofol, opioid, and Bispectral Index (BIS) monitoring were administered as necessary to maintain moderate-to-deep sedation. The opioids used were a bolus of alfentanil or remifentanil infusion. The discharge time, consumption of propofol and opioid, adverse events, diagnostic accuracy, and sensitivity and specificity for malignancy, were compared., Results: Tissue acquisition was achieved in 123 patients (alfentanil group, n = 64; remifentanil group, n = 59). The discharge time of the remifentanil group (16.5 ± 3.2 min) was significantly shorter than that of the alfentanil group (19.0 ± 4.9 min, P = 0.001). The consumption of propofol, adverse events, diagnostic accuracy, sensitivity, and specificity for malignancy in the alfentanil group were not significantly different from those in the remifentanil group., Conclusions: Use of alfentanil or remifentanil for target-controlled infusion of propofol-BIS monitoring can provide good sedative and diagnostic quality for endoscopic ultrasound-guided tissue acquisition. However, remifentanil resulted in faster recovery than alfentanil., (© 2022. The Author(s).)

Objective: To investigate the effects of Butylphthalide on the expressions of HMGB1 and RAGE in frontal lobe of rats after chronic sleep deprivation., Methods: Chronic sleep deprivation and butylphthalide treatment was performed in Sprague Dawley(SD)rats and the rats were divided into three groups ( n ＝6): platform control group, chronic sleep deprivation group and chronic sleep deprivation + butylphthalide intervention group. Rats suffering chronic sleep deprivation were put in multiple platforms box for 18 h per day and sleep deprivation lasted for 28 days. Rats in butylphthalide intervention group were intraperitoneally injected with butylphthalide 100 mg/(kg·d) for 14 days after sleep deprivation. After collecting brains, high-mobility group box (HMGB1) and nuclear transcription factor kappB (NF-κB)p65 were detected by immunohistochemistry. The expression of HMGB1, silent information regulator of transcription 1 (SIRT1), receptor for advanced glycation end-products (RAGE) and NF-κB in frontal lobe were determinated by Western blot., Results: Compared with platform control group, the expression levels of HMGB1, RAGE and nuclear NF-κB p65 were increased significantly, while the expression of SIRT1 was decreased siginificantly in frontal lobe of chronic sleep deprivation group (all P ＜0.05). Compared with chronic sleep deprivation group, the expression levels of of HMGB1, RAGE and nuclear NF-κB p65 were decreased significantly, while the expression of SIRT1 was increased significantly in chronic sleep deprivation + butylphthalide intervention group (all P ＜0.05)., Conclusion: Butylphthalide can inhibit HMGB1/RAGE/NF-κB pathway in frontal lobe of rats after chronic sleep deprivation by changing the expression of HMGB1 and RAGE, and reducing the nuclear translocation of NF-κBp65.

A carbazolide- bis (NHC) Ni II catalyst (1; NHC, N -heterocyclic carbene) for selective CO 2 photoreduction was designed herein by a one-stone-two-birds strategy. The extended π-conjugation and the strong σ/π electron-donation characteristics (two birds) of the carbazolide fragment (one stone) lead to significantly enhanced activity for photoreduction of CO 2 to CO. The turnover number (TON) and turnover frequency (TOF) of 1 were ninefold and eightfold higher than those of the reported pyridinol- bis (NHC) Ni II complex at the same catalyst concentration using an identical Ir photosensitizer, respectively, with a selectivity of ∼100%. More importantly, an organic dye was applied to displace the Ir photosensitizer to develop a noble-metal-free photocatalytic system, which maintained excellent performance and obtained an outstanding quantum yield of 11.2%. Detailed investigations combining experimental and computational studies revealed the catalytic mechanism, which highlights the potential of the one-stone-two-birds effect.

Background: Gene expression analysis can provide useful information for analyzing complex biological mechanisms. However, many reported findings are unrepeatable due to small sample sizes relative to a large number of genes and the low signal-to-noise ratios of most gene expression datasets., Results: Meta-analysis of multi-data sets is an efficient method for tackling the above problem. To improve the performance of meta-analysis, we propose a novel meta-analysis framework. It consists of two parts: (1) a novel data augmentation strategy. Various cross-platform normalization methods exist, which can preserve original biological information of gene expression datasets from different angles and add different "perturbations" to the dataset. Using such perturbation, we provide a feasible means for gene expression data augmentation; (2) elastic data shared lasso (DSL-[Formula: see text]). The DSL-[Formula: see text] method spans the continuum between individual models for each dataset and one model for all datasets. It also overcomes the shortcomings of the data shared lasso method when dealing with highly correlated features. Comprehensive simulation experiment results show that the proposed method has high prediction and gene selection performance. We then apply the proposed method to non-small cell lung cancer (NSCLC) blood gene expression data in order to identify key tumor-related genes. The outcomes of our experiment indicate that the method could be used for identifying a set of robust disease-related gene signatures that may be used for NSCLC early diagnosis or prognosis or even targeting., Conclusion: We propose a novel and effective meta-analysis method for biological research, extrapolating and integrating information from multiple gene expression datasets., (© 2022.

Background: Titanium (Ti) is one of the most popular implant materials, and its surface titanium dioxide (TiO 2 ) provides good biocompatibility. The coagulation of blood on Ti implants plays a key role in wound healing and cell growth at the implant site; however, researchers have yet to fully elucidate the mechanism underlying this process on TiO 2 . Methods: This study examined the means by which blood coagulation was affected by the crystal structure of TiO 2 thin films (thickness < 50 nm), including anatase, rutile, and mixed anatase/rutile. The films were characterized in terms of roughness using an atomic force microscope, thickness using an X-ray photoelectron spectrometer, and crystal structure using transmission electron microscopy. The surface energy and dielectric constant of the surface films were measured using a contact angle goniometer and the parallel plate method, respectively. Blood coagulation properties (including clotting time, factor XII contact activation, fibrinogen adsorption, fibrin attachment, and platelet adhesion) were then assessed on the various test specimens. Results: All of the TiO 2 films were similar in terms of surface roughness, thickness, and surface energy (hydrophilicity); however, the presence of rutile structures was associated with a higher dielectric constant, which induced the activation of factor XII, the formation of fibrin network, and platelet adhesion. Conclusions: This study provides detailed information related to the effects of TiO 2 crystal structures on blood coagulation properties on Ti implant surfaces.

We report the draft genome sequence of Stenotrophomonas maltophilia strain KJ, which was isolated from a sputum sample from a patient with a respiratory tract infection. Multilocus sequence typing analysis suggested that strain KJ belongs to a novel S. maltophilia sequence type.

Objective: To investigate the molecular epidemiological characteristics of common δβ-thalassemia/hereditary persistence of fetal hemoglobin(HPFH) in the prepregnant population in Huadu, and to provide a laboratory basis for prevention and control of thalassemia., Methods: Blood samples of childbearing age people in Huadu District of Guangzhou who participated in free thalassemia testing from January 2016 to July 2021 were collected for hematological parameters analysis and hemoglobin electrophoresis. Chinese G γ + ( A γδβ) 0 -thalassemia, SEA -HPFH and Taiwanese deletion β-thalassemia were detected by Gap-PCR in the samples with higher HbF(≥5%). Primers were designed for the proximal HBG1 and HBG2 promoter, and the point mutations in the proximal promoter region were detected by Sanger sequencing. Hematology parameters data were statistically analyzed., Results: Among 27 088 samples, Thirteen cases of Chinese G γ + ( A γδβ) 0 -thalassemia and thirty-three cases of SEA -HPFH were detected, which including 3 cases of Chinese G γ + ( A γδβ) 0 /β N compounded with -- SEA /αα and three cases of SEA -HPFH/β N compounded with -- SEA /αα. 6 carriers with A γ-196 C>T were also detected; No Taiwanese thalassemia genetype was detected. The total detection rate of common δβ-thalassemia/HPFH was 0.19% (52/27 088). There were significant differences in the levels of MCV, MCH, HbA 2 , and HbF among Chinese G γ + ( A γδβ) 0 -thalassemia, SEA -HPFH, A γ-196 C>T (P<0.001). The hematological parameters of A γ-196C>T combined with α 0 -thalassemia were similar to those of Chinese G γ + ( A γδβ) 0 -thalassemia carriers, and only HbA 2 was significantly lower than that of the latter, which was helpful for clinical identification., Conclusion: δβ-thalassemia/HPFH should be included in the scope of thalassemia prevention program in the prepregnant population in Huadu District, and hematological parameters can provide some basis for identifying different types of δβ-thalassemia/HPFH.

Known as burgeoning contaminants, the bioavailability of rare earth elements (REEs) can be determined using diffusive gradients in thin films (DGT). As Daya Bay (South China) has been under serious anthropogenic influences, the present study examined the distribution of REEs in surface sediments and their possible ecological risks in the bay. The range of DGT-labile concentrations of REEs (∑REEs) was from 5.67 μg/L to 8.41 μg/L, with an average of 7.34 μg/L. Results of assessment of single REE toxicity revealed that the risk quotient (RQ) values of Y, Ce and Yb were >1, indicating that their potential negative impacts on the nearby environment. However, analysis of the integral toxicity of REE mixtures through assessment of probabilistic ecotoxicological risks showed that there was a negligibly low probability of toxicity of PRE surface sediments to aquatic organisms in the study area., (Copyright © 2022 Elsevier Ltd.

Background: Surgical scheduling, specifically the day of the week on which surgery is performed, has been associated with various postoperative outcomes in patients undergoing lower extremity joint arthroplasty., Purpose: We sought to investigate surgical scheduling as a potential modifiable factor for patient quality metrics and related costs., Methods: In a retrospective prognostic study, all total knee and total hip arthroplasty (TKA/THA) cases that took place in 2017 to 2018 at a multihospital academic health system were queried. Patients were separated by the day of the week the surgery was performed, with Monday/Tuesday compared to Thursday/Friday. Outcomes included length of stay (LOS) (extended LOS defined as 3 days or longer), cost, and complications. Multivariable regression models measured associations between scheduling of surgery and outcomes; odds ratios (OR) and 95% confidence intervals (CIs) are reported., Results: Overall, 1,571 TKA and 992 THA patients were included (65% and 35%, respectively, performed on Monday/Tuesday and 70% and 30%, respectively, performed on Thursday/Friday). Patients undergoing TKA on Monday/Tuesday versus Thursday/Friday had higher American Society of Anesthesiologists scores (42% vs 33% with score of 3 or higher) but less often an extended LOS (31% vs 54%; adjusted OR: 2.76, 95% CI: 2.22-3.46), lower skilled nursing facility costs (unadjusted mean, $12,515 vs $14,154) and lower home health aide costs (unadjusted mean, $3,793 vs $4,192). Similar patterns were observed in THA patients., Conclusion: These results from institutional data suggest that surgical scheduling is a modifiable factor possibly associated with postoperative outcomes. Furthermore, more rigorous study is warranted., Competing Interests: Declaration of Conflicting Interests: The author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: Sofia Ahsanuddin, BA; Hsin-Hui Huang, MD, PhD; Aakash Keswani, MD; Jashvant Poeran, MD, PhD; and Daniel J.

In 2020, approximately 9.3 billion tons of crustaceans were consumed, and 45-48% of shrimp shell (SS) by-products were discarded as waste. In this study, the SS of Litopenaeus vannamei was fermented by Lactobacillus plantarum LV33204, Stenotrophomonas maltophilia LV2122 (strong proteolytic activity), and Aeromonas dhakensis LV1111 (chitin-degrading activity), and the optimal fermentation conditions of liquid-fermented SS was established. Contents of total peptide, astaxanthin, and total phenolic content of the fermented SS were significantly higher than that of unfermented SS. In the presence of fermented SS, glucose uptake and insulin resistance of TNF-α-stimulated FL83B hepatocytes were markedly improved. Furthermore, daily oral supplement of fermented SS to streptozotocin (STZ)/nicotinamide (NA)-induced diabetic rats for 7 weeks significantly reduced plasma glucose and insulin resistance. Meanwhile, ingestion of fermented SS might enhance hepatic catabolism of glucose by increasing hexokinase and glucose-6-phosphate dehydrogenase activity and decreasing glucose-6-phosphatase activity. In addition, the fermented SS downregulated plasma total cholesterol (TG), triglycerides (TCs), low-density lipoprotein cholesterol (LDL-C), liver TG, and TC and lipid peroxidation levels in diabetic rats. In conclusion, a biorefinery process for waste SS was established through mixed strain fermentation. The in vitro and in vivo data reveal that the fermented SS is a promising functional food for the management of diabetic hyperglycemia and hyperlipidemia.

Background: Disparate COVID-19 outcomes have been observed between Hispanic, non-Hispanic Black, and White patients. The underlying causes for these disparities are not fully understood., Methods: This was a retrospective study utilizing electronic medical record data from five hospitals within a single academic health system based in New York City. Multivariable logistic regression models were used to identify demographic, clinical, and lab values associated with in-hospital mortality., Results: A total of 3,086 adult patients with self-reported race/ethnicity information presenting to the emergency department and hospitalized with COVID-19 up to April 13, 2020, were included in this study. While older age (multivariable odds ratio (OR) 1.06, 95% CI 1.05-1.07) and baseline hypoxia (multivariable OR 2.71, 95% CI 2.17-3.36) were associated with increased mortality overall and across all races/ethnicities, non-Hispanic Black (median age 67, interquartile range (IQR) 58-76) and Hispanic (median age 63, IQR 50-74) patients were younger and had different comorbidity profiles as compared to non-Hispanic White patients (median age 73, IQR 62-84; p < 0.05 for both comparisons). Among inflammatory markers associated with COVID-19 mortality, there was a significant interaction between the non-Hispanic Black population and interleukin-1-beta (interaction p-value 0.04)., Conclusions: This analysis of a multiethnic cohort highlights the need for inclusion and consideration of diverse populations in ongoing COVID-19 trials targeting inflammatory cytokines., Competing Interests: EW has consulting agreements with and/or is on the scientific advisory board for Merck, Elstar, Janssen, Jounce, Related Sciences, Synthekine, and Surface Oncology.

Cryphonectriaceae is a diaporthalean family containing important plant pathogens of which Cryphonectriaparasitica is the most notorious one. An emerging stem blight disease on Elaeocarpusapiculatus (Elaeocarpaceae) and E.hainanensis was observed in Guangdong Province of China recently. Typical Cryphonectria blight-like symptoms including cankers on tree barks with obvious orange conidial tendrils were observed. Forty-eight isolates were obtained from diseased tissues and conidiomata formed on the hosts E.apiculatus and E.hainanensis . These isolates were further identified based on both morphology and molecular methods using the combined sequence data of the internal transcribed spacer (ITS) region, large subunit of the nrDNA (LSU), the translation elongation factor 1-alpha ( tef1 ) and DNA-directed RNA polymerase II second largest subunit (rpb2) genes. As a result, the fungus represents an undescribed genus and species within the family Cryphonectriaceae. Hence, Pseudocryphonectriaelaeocarpicola gen. et sp. nov. is proposed herein to represent these isolates from diseased barks of E.apiculatus and E.hainanensis . Pseudocryphonectria differs from the other genera of Cryphonectriaceae in having dimorphic conidia. Further inoculation results showed that P.elaeocarpicola is the causal agent of this emerging blight disease in China, which can quickly infect and kill the hosts E.apiculatus and E.hainanensis ., (Hua-Yi Huang, Huan-Hua Huang, Dan-Yang Zhao, Ti-Jiang Shan, Li-Li Hu.)

Metabolic surgery is a promising treatment for obese individuals with type 2 diabetes mellitus (T2DM), but the mechanism is not completely understood. Current understanding of the underlying ameliorative mechanisms relies on alterations in parameters related to the gastrointestinal hormones, biochemistry, energy absorption, the relative composition of the gut microbiota, and sera metabolites. A total of 13 patients with obesity and T2DM undergoing metabolic surgery treatments were recruited. Systematic changes of critical parameters and the effects and markers after metabolic surgery, in a longitudinal manner (before surgery and three, twelve, and twenty-four months after surgery) were measured. The metabolomics pattern, gut microbiota composition, together with the hormonal and biochemical characterizations, were analyzed. Body weight, body mass index, total cholesterol, triglyceride, fasting glucose level, C-peptide, HbA1c, HOMA-IR, gamma-glutamyltransferase, and des-acyl ghrelin were significantly reduced two years after metabolic surgery. These were closely associated with the changes of sera metabolomics and gut microbiota. Significant negative associations were found between the Eubacterium eligens group and lacosamide glucuronide, UDP-L-arabinose, lanceotoxin A, pipercyclobutanamide B, and hordatine B. Negative associations were identified between Ruminococcaceae UCG-003 and orotidine, and glucose. A positive correlation was found between Enterococcus and glutamic acid, and vindoline. Metabolic surgery showed positive effects on the amelioration of diabetes and metabolic syndromes, which were closely associated with the change of sera metabolomics, the gut microbiota, and other disease-related parameters.

Auditory steady-state response (ASSR) is a translational biomarker for several neurological and psychiatric disorders, such as hearing loss, schizophrenia, bipolar disorder, autism, etc. The ASSR is sinusoidal electroencephalography (EEG)/magnetoencephalography (MEG) responses induced by periodically presented auditory stimuli. Traditional frequency analysis assumes ASSR is a stationary response, which can be analyzed using linear analysis approaches, such as Fourier analysis or Wavelet. However, recent studies have reported that the human steady-state responses are dynamic and can be modulated by the subject's attention, wakefulness state, mental load, and mental fatigue. The amplitude modulations on the measured oscillatory responses can result in the spectral broadening or frequency splitting on the Fourier spectrum, owing to the trigonometric product-to-sum formula. Accordingly, in this study, we analyzed the human ASSR by the combination of canonical correlation analysis (CCA) and Holo-Hilbert spectral analysis (HHSA). The CCA was used to extract ASSR-related signal features, and the HHSA was used to decompose the extracted ASSR responses into amplitude modulation (AM) components and frequency modulation (FM) components, in which the FM frequency represents the fast-changing intra-mode frequency and the AM frequency represents the slow-changing inter-mode frequency. In this paper, we aimed to study the AM and FM spectra of ASSR responses in a 37 Hz steady-state auditory stimulation. Twenty-five healthy subjects were recruited for this study, and each subject was requested to participate in two auditory stimulation sessions, including one right-ear and one left-ear monaural steady-state auditory stimulation. With the HHSA, both the 37 Hz (fundamental frequency) and the 74 Hz (first harmonic frequency) auditory responses were successfully extracted. Examining the AM spectra, the 37 Hz and the 74 Hz auditory responses were modulated by distinct AM spectra, each with at least three composite frequencies. In contrast to the results of traditional Fourier spectra, frequency splitting was seen at 37 Hz, and a spectral peak was obscured at 74 Hz in Fourier spectra. The proposed method effectively corrects the frequency splitting problem resulting from time-varying amplitude changes. Our results have validated the HHSA as a useful tool for steady-state response (SSR) studies so that the misleading or wrong interpretation caused by amplitude modulation in the traditional Fourier spectrum can be avoided.

Objectives: Insufficient distance between membranous septum (MS) length and implant depth (ID) may aggravate mechanical compression of the conduction tissue by transcatheter aortic valve replacement (TAVR) prosthesis. We investigated the implication of MS length measured in the coronal view (coronal MS length) compared with infra-annular MS length from stretched vessel image to predict conduction disturbances following TAVR with CoreValve/Evolut R valves (Medtronic, Minneapolis, Minn)., Methods: Among 195 consecutive patients undergoing TAVR with CoreValve/Evolut R valves, we evaluated coronal, infra-annular MS lengths and ID, as well as MS length minus ID (ΔMSID) using pre-TAVR computed tomography and postprocedural angiography., Results: Within 30 days, 6 (3.1%) required permanent pacemaker implantation and 31 (16.4%) developed left bundle branch block. When taking into account pre- and postprocedural parameters, multivariable logistic regression analysis revealed either coronal ΔMSID (odds ratio, 0.80; 95% confidence interval, 0.72-0.89; P < .001; cutoff point, 3.2 mm) or infra-annular ΔMSID (odds ratio, 0.84; 95% confidence interval, 0.76-0.92; P < .001; cutoff point, -0.2 mm) emerged as the only modifiable predictor of conduction disturbances. The area under the curve of coronal ΔMSID and infra-annular ΔMSID for predicting the occurrence of conduction disturbances were comparable (0.717 in coronal ΔMSID vs 0.708 in infra-annular ΔMSID; P = .761), but more patients could be guided by coronal MS length than infra-annular MS length (95.9% vs 87.2%; P = .002)., Conclusions: Preprocedural assessment of MS length should be routinely adopted to determine the optimal ID to mitigate individual patient susceptibility to conduction disturbances after TAVR with self-expanding valves., (Copyright © 2020 The American Association for Thoracic Surgery.

Background: In China, coronary artery abnormalities (CAAs) secondary to Kawasaki disease (KD) tend to have an increased occurrence. We hypothesize that Chinese children with KD may possess several unique CAA risks, and the predictive efficacy of multiple scoring systems in Chinese patients are still to be further studied., Methods: Two hundred and three KD patients were recruited. Using multivariable analysis, independent predictors of CAAs were combined into a scoring system. Subsequently, CAA risks of our patients were evaluated by the newly established scoring system and eight other published scoring systems., Results: Seventeen (8.37%) KD patients were identified as CAAs. The newly established scoring system contained the following 5 independent predictors: days of illness at initial treatment ≥7, redness and swelling of extremities, hematocrit ≤33%, percentage of monocytes ≥8.89%, and procalcitonin ≥0.5 ng/mL. The AUC value of newly established scoring system was 0.685 with a sensitivity of 41.18% and a specificity of 84.41%, higher than Harada score, Egami score, Kobayashi score, Sato score, San Diego score, Formosa score, and Tang score, whereas lower than Hua score., Conclusions: Days of illness at initial treatment ≥7 and procalcitonin are unique predictors of CAAs in newly established scoring system. Taking into account different identification criteria and analytical methodologies, there is still some heterogeneity among different scoring systems., Impact: The newly established scoring system contains the five independent predictors. Days of illness at initial treatment ≥7 and PCT are unique predictors of CAAs in our study, compared with 8 other systems. The AUC value of newly established scoring system is 0.685, similar to Hua score. There is some heterogeneity among different scoring systems., (© 2021.

The physical interactions between wearable lower limb robots and humans have been investigated to inform effective robot design for walking augmentation. However, human-robot interactions when internal faults occur within robots have not been systematically reported, but it is essential to improve the robustness of robotic devices and ensure the user's safety. This paper aims to (1) present a methodology to characterize the behavior of the robotic transfemoral prosthesis as an effective wearable robot platform while interacting with the users in the presence of internal faults, and (2) identify the potential data sources for accurate detection of the prosthesis fault. We first obtained the human perceived response in terms of their walking stability when the prosthesis control fault (inappropriate intrinsic control output/command) was emulated/applied in level-ground walking. Then the measurements and their features, obtained from the transfemoral prosthesis, were examined for the emulated faults that elicited a sense of instability in human users. The optimal features that contributed the most in separating faulty interaction from the normal walking condition were determined using two machine-learning-based approaches: One-Class Support Vector Machine (OCSVM) and Mahalanobis Distance (MD) classifier. The OCSVM anomaly detector could achieve an average sensitivity of 85.7 % and an average false alarm rate of 1.7 % with a reasonable detecting time of 147.6 ms for detecting emulated control errors among all subjects. The result demonstrates the potential of using machine-learning-based schemes in identifying prosthesis control faults based on intrinsic sensors on the prosthesis. This study presents a procedure to study human-robot fault tolerance and inform the future design of robust prosthesis control.

Performing esophagogastroduodenoscopy (EGD) in recently occurring peri-coronary artery disease (CAD) accident settings is always a dilemma. This study used the Taiwan National Health Insurance Research Database to identify patients with CAD and gastrointestinal bleeding who had received EGD or not between 2000 and 2013.The final population included in this study was 15,147 individuals, with 3801 individuals having received EGD (study cohort group) and 11,346 individuals not having received EGD (comparison cohort group). We initially performed a sensitivity test for CAD recurrence-related factors using multivariable Cox regression during the tracking period. A relatively earlier EGD intervention within one week demonstrated a lower risk of CAD recurrence (adjusted HR = 0.712). Although there were no significant differences in the overall tracking period, the adjusted HR of CAD recurrence was still lower in patients in the EGD group. Furthermore, our findings revealed that there were no remarkably short intervals to CAD recurrence in the study group. The Kaplan-Meier survival curve demonstrated that individuals who underwent EGD were not associated with a significantly increased CAD recurrence rate compared with the control (Log-rank test, p = 0.255). CAD recurrence is always an issue in recent episodes of peri-CAD accident settings while receiving EGD. However, there is not a higher risk in comparison with the normal population in our study, and waiting periods may not be required.

Despite the recognized importance of grammar knowledge to the reading comprehension of EFL learners, research findings on the relationships among grammar knowledge, vocabulary, and reading comprehension are inconclusive. Attention needs to be paid to issues such as the distinct roles of the two grammar knowledge components of form and meaning, and the direct and mediating roles of vocabulary in EFL reading comprehension. This study recruited 1,149 sixth graders as research participants to evaluate these issues. The measurement tools were standardized EFL competence tests for vocabulary size, grammar forms and meanings, and reading comprehension. Structural equation modeling (SEM) regression models indicated that vocabulary played a more-significant role in reading comprehension than grammar knowledge; moreover, the effects of grammar knowledge were reduced but still significant when grammar meanings were excluded. The SEM mediating model of this study also indicated that grammar knowledge not only exerted a direct effect on reading comprehension but also indirectly influenced reading comprehension via vocabulary., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Hu, Sung, Liang, Chang and Chou.)

Childhood-onset schizophrenia (COS) is an unusual severe neurodevelopmental disorder of unknown etiology. In this study, we aimed to survey the missense variants in new cases of COS and also identify possible pathology biomarkers for COS. We found one list of mutated genes such as TTN, MUC12, and MUC2, which are the candidates to be involved in the etiology of COS. Next, we used WGSNA to predict COS disease-related genes and identified differential DNA methylation among COS disease groups, COS dangerous groups, and normal groups and found eight methylation sites that can be used as the diagnostic biomarkers. A total of six key genes are obtained through the intersection analysis between weighted correlation network analysis (WGCNA) mode, methylation-related genes, and differentially expressed genes (DGenes). These genes may play important roles in the progression of COS and serve as the potential biomarkers for future diagnosis. Our results might help to design the molecule or gene-targeted drugs for COS., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 He, Zhou, Qi, Huang, Guan, Luo, Cheng and Zheng.)

Mercury (Hg) is a global, persistent and inevitable pollutant, the toxicity of which is mostly reflected in its species including inorganic Hg (InHg) and methyl mercury (MeHg). Using diffusive gradients in thin films (DGT) is deemed as a reliable technique to determine the bioavailability of pollutants. This study is the first attempt to assess the integrated toxicity of mercury species mixtures in sediments to the aquatic biota based on the DGT technique. In the course, the Daya Bay under serious anthropogenic influences was selected as the study case. The results showed that the DGT concentrations of InHg and MeHg were detected as 0.30-1.93 μg/L and 0.28-1.94 μg/L respectively in the surface sediments collected from the Daya Bay. In terms of the toxicity of single mercury species, the risk quotient (RQ) values of InHg and MeHg significantly exceeded 1, indicating that the adverse effects of InHg and MeHg should not be ignored. In terms of the integrated toxicity of mercury species mixtures, the probabilistic biological risk assessment results demonstrate that Daya Bay features low (3.32%) probability of toxic effects in its surface sediments to the aquatic biota., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier B.V.

Objective: To investigate the efficacy and safety of house dust mite (HDM) allergen subcutaneous specific immunotherapy (SCIT) in patients with allergic rhinitis (AR) with single dust mite allergy and multiple allergen allergy. Methods: A retrospective study was conducted. A total of 372 patients with allergic rhinitis induced by house dust mite were diagnosed in the allergy clinic of General Hospital of North Theater Command from January 2013 to January 2018.They were treated with house dust mite allergen preparation for standardized SCIT for 3 years or more, and had complete follow-up data. The age ranged from 5 to 55 years, the median age was 13 years, and the average age was (19.4±14.7) years; 216 males and 156 females. According to their age, they were divided into the older group (age >14 years) and younger group (age ≤ 14 years). According to the number of allergens, they were divided into single group (only HDM group allergic to house dust mites) and multi recombination (including 2 or more allergens including house dust mites). The multi recombination was further divided into HDM+1 group, HDM+2 group, HDM+3 group, HDM+4 and above group. Before treatment (T0), 1 year (T1) and 3 years (T2) after SCIT treatment, the patients in each group established files, analyzed and compared the average total nasal symptoms score (TNSS), total non nasal symptoms score (TNNSS), visual analogue scale (VAS), total medicine score (TMS) and rhinoconjunctivitis quality of life questionnaire (RQLQ), and evaluated the clinical efficacy of the treatment and the comparison of various scores in the efficacy of SCIT with different allergens and ages. Record the occurrence of local and systemic adverse reactions of all patients during treatment, and evaluate the safety of SCIT. All scores are measurement data that do not conform to normal distribution. Mann-Whitney U and Kruskai-Wallis test of independent samples are used for inter group comparison, and Bonferroni correction is used for further pairwise comparison; Chi square test and continuity correction method were used for the comparison between count data groups such as the incidence of adverse reactions and the effective rate of TNSS, and a-division method was used for further pairwise comparison. Results: After SCIT treatment, the scores of TNSS, TNNSS, TMS, VAS and RQLQ in T1 and T2 were significantly lower than those in T0, and the scores in T2 were significantly lower than those in T1 ( Z =-11.168, -4.786, -6.639, -13.012, -10.652 in T0 vs T1; Z =-13.527, -8.746, -13.397, -14.477, -11.833 in T0 vs T2; Z =-4.721, -4.607, -10.020, -7.180, -5.721 in T1 vs T2; P <0.05). In T1 and T2, compared with the older group, the scores of TNSS, TNNSS, TMS, VAS and RQLQ in younger group were lower, and the differences of various indexes were statistically significant(the median scores of T1: M younger =3.0, 1.0, 2.0, 4.0, 2.6, M older =5.0, 2.0, 3.0, 5.0, 3.2; the median scores of T2: M younger =3.0, 1.0, 0, 2.0, 1.3, M older =4.0, 1.0, 1.5, 3.0, 2.3; Z T1 =-4.525, -5.830, -4.061, -3.608, -2.785; Z T2 =-3.847, -4.055, -2.820, -2.998, -3.418; P <0.05). In T1 and T2, the scores of TNSS, VAS and RQLQ in a single group after SCIT treatment were lower than those in multiple recombination(the median scores of T1: M single =4.0, 4.0, 2.6, M multiple =5.0, 5.0, 3.2; the median scores of T2: M single =3.0, 2.0, 1.4, M multiple =4.0, 3.0, 2.1), and the difference was statistically significant ( Z T1 =-3.002, -2.092, -1.977; Z T2 =-3.354, -2.469, -2.116; P <0.05). There was no significant difference in TMS (the median score during T1 period: M single =2.0, M multiple =3.0, Z T1 =-1.130; the median score during T2 period: M single =1.0, M multiple =1.0, Z T2 =-1.544; P >0.05). Further comparison within the group showed that there was no significant difference in the improvement rate of TNSS during T2 period among HDM group, HDM+1 group, HDM+2 group and HDM+3 group (HDM vs HDM+1 group χ 2 =0.277, HDM vs HDM+2 group χ 2 =0.78, HDM vs HDM+3 group χ 2 =0.075, HDM+1 vs HDM+2 group χ 2 =0.057, HDM+1 vs HDM+3 group χ 2 =0.019, HDM+2 vs HDM+3 group χ 2 =0.003; P >0.005), the improvement rates were 92.5%, 90.3%, 89.1% and 89.5%. Respectively in HDM group,HDM+1 group, HDM+2 group, HDM+3 group, compared with HDM+4 and above group, the difference was statistically significant (χ 2 =26.144, 13.254, 15.144, 8.808; P <0.005). The improvement rate of TNSS in HDM+4 and above group was 60.9%. 122 patients had local adverse reactions during the treatment of SCIT, accounting for 32.8%. The local adverse reactions were 759 injections (15 336 injections in total), accounting for 4.95%. Most of them were swelling, dizziness, induration and pruritus at the injection site, which could be relieved by oral antihistamines or within 2 hours. There were 2 cases of local urticaria, once for each case. The symptoms were relieved within 1 week after oral antihistamine. No serious systemic adverse reactions occurred. Conclusion: Standardized SCIT may be a safe and effective treatment for AR patients, and the type of allergen may be one of the important factors affecting the efficacy of SCIT. The efficacy of SCIT was significant in AR patients with three or less allergens other than house dust mite.

Background and objective: Xenotransplantation of porcine islets to human recipients has been investigated as a potential cure for type 1 diabetes. However, the porcine islets have poor insulin secretion capacity compared with human islets. The objective of this study was to evaluate the effect of photobiomodulation therapy (PBMT) in insulin secretion on isolated porcine islets. Methods: Eight pancreata were harvested from crossbred market porcine and the islets were isolated from the pancreas. The isolated islets were treated with PBMT (wavelength: 633 nm and dosages: 0.0, 15.6, and 31.3 J/cm 2 ) followed by 30-min incubation in low (3.0 mM) or high (16.7 mM) glucose. The relative percentage differences on insulin secretion between three dosages were compared in low and high glucose, respectively. Results: Insulin secretion was higher in samples exposed to 15.6 J/cm 2 PBMT in low glucose ( p  < 0.05), but not in high glucose. When evaluating sex differences, male islets had higher insulin secretion by 15.6 J/cm 2 PBMT in low glucose compared with females ( p  < 0.05). No significant differences were seen in high glucose. When compared within the control groups (0.0 J/cm 2 PBMT), the relative changes on insulin secretion in high glucose was significantly higher on male islets ( p  < 0.05), but not on female islets. Conclusions: PBMT may increase insulin secretion on isolated porcine islets in basal condition, but it may not improve islets' glucose responsiveness to secrete insulin. Male porcine islets may respond to PBMT and glucose stimuli better than female islets on insulin secretion.

As the power conversion efficiency (PCE) of organic photovoltaics (OPVs) approaches 19%, increasing research attention is being paid to enhancing the device's long-term stability. In this study, a robust interface engineering of graphene oxide nanosheets (GNS) is expounded on improving the thermal and photostability of non-fullerene bulk-heterojunction (NFA BHJ) OPVs to a practical level. Three distinct GNSs (GNS, N-doped GNS (N-GNS), and N,S-doped GNS (NS-GNS)) synthesized through a pyrolysis method are applied as the ZnO modifier in inverted OPVs. The results reveal that the GNS modification introduces passivation and dipole effects to enable better energy-level alignment and to facilitate charge transfer across the ZnO/BHJ interface. Besides, it optimizes the BHJ morphology of the photoactive layer, and the N,S doping of GNS further enhances the interaction with the photoactive components to enable a more idea BHJ morphology. Consequently, the NS-GNS device delivers enhanced performance from 14.5% (control device) to 16.5%. Moreover, the thermally/chemically stable GNS is shown to stabilize the morphology of the ZnO electron transport layer (ETL) and to endow the BHJ morphology of the photoactive layer grown atop with a more stable thermodynamic property. This largely reduces the microstructure changes and the associated charge recombination in the BHJ layer under constant thermal/light stresses. Finally, the NS-GNS device is demonstrated to exhibit an impressive T 80 lifetime (time at which PCE of the device decays to 80% of the initial PCE) of 2712 h under a constant thermal condition at 65 °C in a glovebox and an outstanding photostability with a T 80 lifetime of 2000 h under constant AM1.5G 1-sun illumination in an N 2 -controlled environment., (© 2022 Wiley-VCH GmbH.)

This nursing experience describes the application of "self-efficacy theory" to a patient with low self-efficacy who was diagnosed with advanced esophageal cancer. The nursing period was from December 3rd, 2020 to December 23rd, 2020. Medical records, interview assessment, and observation showed that the patient had ineffective airway clearance, which caused him to be in and out of the hospital several times, resulting in lower self-efficacy. In addition to applying the "self-efficacy theory", the authors referenced the patient's physiological and affective states, vicarious experiences, and performance experiences and used verbal persuasion techniques to assess the patient for nursing and interventions. During the nursing period, we established a good therapeutic relationship with the patient. We provided him with personalized nursing interventions to improve his physiological and affective states. These interventions included the administration of medication, posture drainage, and sputum percussion. We also sought the help of people who were close to the patient as participants in the medical care process. We improved self-efficacy by means of verbal persuasion through education and mental support; increased vicarious experience through verbal encouragement and sharing the experiences of other patients; and used a comparative approach to enable the patient to observe changes in his physical status over time. The interventions also improved his performance experience. The patient's airway status improved after his self-efficacy had been enhanced. Based on the results, it is hoped that this study will be a helpful reference on the theory of self-efficacy for nursing staff. It is also hoped that the results will better enable nurses to enhance the self-efficacy of patients using different means such as restoring patient confidence and enhancing the patient - the medical team relationship to further enhance the quality of patient care.

Background: There is a paucity of literature on racial differences across a full total joint arthroplasty (TJA) "episode of care" and beyond. Given various incentives, the Comprehensive Care for Joint Replacement (CJR) program in the U.S. may have impacted preexisting racial differences across this care continuum. The purposes of the present study were (1) to assess trends in racial differences in care/outcome characteristics before, during, and after TJA surgery and (2) to assess if the CJR program coincided with reductions in these racial differences., Methods: This retrospective cohort study includes data on 1,483,221 TJAs (based on Medicare claims data, 2013 to 2018). Racial differences between Black and White patients were assessed for (1) preoperative characteristics (Deyo-Charlson comorbidity index, patient sex, and age), (2) characteristics during hospitalization (length of stay, blood transfusions, and combined complications), and (3) postoperative characteristics (90 and 180-day readmission rates and institutional post-acute care). Additionally, Medicare payments for each period were assessed. Racial differences (Black versus White patients) were expressed in terms of odds ratios (ORs) and 95% confidence intervals (CIs) per year. A "difference-in-differences" analysis (comparing before and after CJR implementation, with non-CJR hospitals being used as controls) estimated the association of the CJR program with changes in racial differences., Results: In both 2013 and 2018, Black patients (n = 74,390; 5.0%) were more likely than White patients to have a higher Deyo-Charlson comorbidity index (score of >0) (OR = 1.32 [95% CI = 1.28 to 1.36] and OR = 1.32 [95% CI = 1.28 to 1.37]), to require more transfusions (OR = 1.55 [95% CI = 1.49 to 1.62] and OR = 1.77 [95% CI = 1.56 to 2.01]), to be discharged to institutional post-acute care (OR = 1.40 [95% CI = 1.36 to 1.44] and OR = 1.49 [95% CI = 1.43 to 1.56]), and to be readmitted within 90 days (OR = 1.38 [95% CI = 1.32 to 1.44] and OR = 1.21 [95% CI = 1.13 to 1.29]) (p < 0.05 for all). Adjusted difference-in-differences analyses demonstrated that the CJR program coincided with reductions in racial differences in 90-day readmission (-1.24%; 95% CI, -2.46% to -0.03%) and 180-day readmission (-1.28%; 95% CI, -2.52% to -0.03%) (p = 0.044 for both)., Conclusions: Racial differences persist among patients managed with TJA. The CJR program coincided with reductions in some racial differences, thus identifying bundle design as a potential novel strategy to target racial disparities., Level of Evidence: Prognostic Level III.

Background: Aortic valve stenosis (AS) is a common, lethal cardiovascular disease. There is no cure except the valve replacement at last stage. Therefore, an understanding of the detail mechanism is imperative to prevent and intervene AS. Metabolic syndrome (MetS) is one of the major risk factors of AS whereas fructose overconsuming tops the list of MetS risk factors. However, whether the fructose under physiological level induces AS is currently unknown., Methods: The human valve interstitial cells (hVICs), a crucial source to develop calcification, were co-incubated with fructose at 2 or 20 mM to mimic the serum fructose at fasting or post-fructose consumption, respectively, for 24 h. The cell proliferation was evaluated by WST-1 assays. The expressions of osteogenic and fibrotic proteins, PI3K/AKT signaling, insulin receptor substrate 1 and mitochondrial dynamic proteins were detected by Western blot analyses. The mitochondrial oxidative phosphorylation (OXPHOS) was examined by Seahorse analyzer., Results: hVICs proliferation was significantly suppressed by 20 mM fructose. The expressions of alkaline phosphatase (ALP) and osteocalcin were enhanced concurrent with the upregulated PI3K p85, AKT, phospho(p)S473-AKT, and pS636-insulin receptor substrate 1 (p-IRS-1) by high fructose. Moreover, ATP production capacity and maximal respiratory capacity were enhanced in the high fructose groups. Synchronically, the expressions of mitochondrial fission 1 and optic atrophy type 1 were increased., Conclusions: These results suggested that high fructose stimulated the osteogenic differentiation of hVICs via the activation of PI3K/AKT/mitochondria signaling at the early stage. These results implied that high fructose at physiological level might have a direct, hazard effect on the progression of AS., Competing Interests: Conflicts of interest The authors declare no conflicts of interest., (Copyright © 2021 Chang Gung University.

Escherichia coli O157:H7 is one of the most important foodborne pathogens that can persist in leafy green vegetables and subsequently produce biofilms. Biofilm formation is an ongoing concern in the food industry as biofilms are relatively resistant to a variety of antimicrobial treatments. In the present study, we evaluated the combined effects of phage FP43 and mild-heated slightly acidic hypochlorous water (SAHW) in reducing established biofilms on lettuce. Prior to the sequential treatments involving phage-SAHW and SAHW-phage for long-term storage, equal inoculum densities of E. coli O157:H7 and E. coli O91:H- were added on iceberg lettuce surfaces and the lettuce samples were stored at 10 °C for 48 h to allow biofilm formation. The sequential treatment with phage FP43 and SAHW significantly decreased the number of adhered cells, especially the combination of phage FP43 at 25 °C for 2 h and mild-heated SAHW, which considerably eliminated E. coli viable biofilm cells to undetectable levels (>3 log CFU/piece). However, the biofilms were not completely removed, as evidenced via SEM observation. Additionally, sequential treatment with SAHW and phage caused continuous reductions in viable counts, decreasing the viability of E. coli O157:H7 and total E. coli to the lower limit of detection after incubation for 5 d. Meanwhile, bacterial regrowth was observed after treatment with SAHW alone. These results indicated that the combination of phage and SAHW could be considered as a promising strategy to control the formation of E. coli O157:H7 biofilms on lettuce., (Copyright © 2022 Elsevier Ltd.

We extend our previous quantum chemistry calculations of interaction energies for 31 homodimers of small organic functional groups (the SOFG-31 data set) by including 239 heterodimers with monomers selected within the SOFG-31 data set, thus resulting in the SOFG-31+239 data set. The minimum-level theoretical scheme contains (1) the basis set superposition error corrected supermolecule (BSSE-SM) approach for intermolecular interactions; (2) the second-order Møller-Plesset perturbation theory (MP2) with the Dunning's aug-cc-pVXZ (X = D, T, Q) basis sets for the geometry optimization and correlation energy calculations; and (3) the single-point energy calculations with the coupled cluster with single, double, and perturbative triple excitations method at the complete basis set limit [CCSD(T)/CBS] using the well-tested extrapolation methods for the MP2 energy calibrations. In addition, we have performed a parallel series of energy decomposition calculations based on the symmetry adapted perturbation theory (SAPT) in order to gain chemical insights. That the above procedure cannot be further reduced has been proven to be very crucial for constructing reliable data sets of interaction energies. The calculated CCSD(T)/CBS interaction energy data can serve as a benchmark for testing or training less accurate but more efficient calculation methods, such as the electronic density functional theory. As an application, we employ a segmental SAPT model previously developed for the SOFG-31 data set to predict binding energies of large heterodimer complexes. These model energy "quanta" can be used in coarse-grained molecular dynamics simulations by avoiding large-scale calculations., Competing Interests: The authors declare no competing financial interest., (© 2022 The Authors.

Rectal adenocarcinoma (READ) constitutes one-third of newly diagnosed colorectal cancer cases. Surgery, chemotherapy and concurrent chemoradiotherapy are the main treatments to improve patient outcomes for READ. However, patients with READ receiving these treatments eventually relapse, leading to a poor survival outcome. The present study collected surgical specimens from patients with READ and determined that cytoplasmic cell division cycle 27 (CDC27) expression was associated with the risk of lymph node metastasis and distant metastasis. Nuclear CDC27 expression was negatively associated with 5-year disease-free survival (DFS) and 5-year overall survival (OS) rates. Multivariate Cox proportional regression analysis showed that nuclear CDC27 was an independent prognostic factor in the patients with READ, especially in those treated with adjuvant chemotherapy. High nuclear CDC27 expression was significantly associated with poorer 5-year DFS (HR, 2.106; 95% CI, 1.275-3.570; P=0.003) and 5-year OS (HR, 2.369; 95% CI, 1.270-4.6810; P=0.005) rates. The data indicated that cytoplasmic CDC27 expression could affect tumor progression and that it plays an important role in metastasis. Nuclear CDC27 expression was markedly associated with poorer survival outcomes and was an independent prognostic factor in patients with postoperative adjuvant chemotherapy-treated READ. Thus, CDC27 expression serves as a potential prognostic marker for rectal tumor progression and chemotherapy treatment., Competing Interests: The authors declare that they have no competing interests., (Copyright: © Chang et al.)
