Abstract

Objectives Racial factors play a significant role in SSc. We evaluated differences in SSc presentations between white patients (WP), Asian patients (AP) and black patients (BP) and analysed the effects of geographical locations. Methods SSc characteristics of patients from the EUSTAR cohort were cross-sectionally compared across racial groups using survival and multiple logistic regression analyses. Results The study included 9162 WP, 341 AP and 181 BP. AP developed the first non-RP feature faster than WP but slower than BP. AP were less frequently anti-centromere (ACA; odds ratio (OR) = 0.4, P < 0.001) and more frequently anti-topoisomerase-I autoantibodies (ATA) positive (OR = 1.2, P = 0.068), while BP were less likely to be ACA and ATA positive than were WP [OR(ACA) = 0.3, P < 0.001; OR(ATA) = 0.5, P = 0.020]. AP had less often (OR = 0.7, P = 0.06) and BP more often (OR = 2.7, P < 0.001) diffuse skin involvement than had WP. AP and BP were more likely to have pulmonary hypertension [OR(AP) = 2.6, P < 0.001; OR(BP) = 2.7, P = 0.03 vs WP] and a reduced forced vital capacity [OR(AP) = 2.5, P < 0.001; OR(BP) = 2.4, P < 0.004] than were WP. AP more often had an impaired diffusing capacity of the lung than had BP and WP [OR(AP vs BP) = 1.9, P = 0.038; OR(AP vs WP) = 2.4, P < 0.001]. After RP onset, AP and BP had a higher hazard to die than had WP [hazard ratio (HR) (AP) = 1.6, P = 0.011; HR(BP) = 2.1, P < 0.001]. Conclusion Compared with WP, and mostly independent of geographical location, AP have a faster and earlier disease onset with high prevalences of ATA, pulmonary hypertension and forced vital capacity impairment and higher mortality. BP had the fastest disease onset, a high prevalence of diffuse skin involvement and nominally the highest mortality.

Abstract

Objective To identify nailfold videocapillaroscopic features and other clinical risk factors for new digital ulcers (DUs) during a 6-month period in patients with systemic sclerosis (SSc). Methods In this multicenter, prospective, observational cohort study, the videoCAPillaroscopy (CAP) study, we evaluated 623 patients with SSc from 59 centers (14 countries). Patients were stratified into 2 groups: a DU history group and a no DU history group. At enrollment, patients underwent detailed nailfold videocapillaroscopic evaluation and assessment of demographic characteristics, DU status, and clinical and SSc characteristics. Risk factors for developing new DUs were assessed using univariable and multivariable logistic regression (MLR) analyses. Results Of the 468 patients in the DU history group (mean ± SD age 54.0 ± 13.7 years), 79.5% were female, 59.8% had limited cutaneous SSc, and 22% developed a new DU during follow-up. The strongest risk factors for new DUs identified by MLR in the DU history group included the mean number of capillaries per millimeter in the middle finger of the dominant hand, the number of DUs (categorized as 0, 1, 2, or ≥3), and the presence of critical digital ischemia. The receiver operating characteristic (ROC) of the area under the curve (AUC) of the final MLR model was 0.738 (95% confidence interval [95% CI] 0.681–0.795). Internal validation through bootstrap generated a ROC AUC of 0.633 (95% CI 0.510–0.756). Conclusion This international prospective study, which included detailed nailfold videocapillaroscopic evaluation and extensive clinical characterization of patients with SSc, identified the mean number of capillaries per millimeter in the middle finger of the dominant hand, the number of DUs at enrollment, and the presence of critical digital ischemia at enrollment as risk factors for the development of new DUs.

16. Emotion, Reason and Political-Legal Bond: Ideas from Greek Literature

Abstract

The traditional representation of (the) Hellenic world relies on the close and symmetric relation between Greek culture, understood as the origin of the Western model, and ‘reason’ (including its legal-political reflexes). This reading dates back to the German neo-humanistic movement of the XIXth century, from Johann Winkelmann to Werner Jaeger and, although its recent (and partial) review by Martha Nussbaum, it moves from a peculiar interpretation of some moments of the Hellenic framework as a whole (mythology, art, literature and philosophy). This perspective mainly aims to remove the role of ‘emotion’ and, more widely, allows the equation ‘Western culture=reason’ or, in a consequent manner, ‘law=reason’. On the contrary Greek world presents a more articulated relation reason-emotion. Within the Hellenic context ‘emotion’, very broadly considered, seems to have a dialectic role: as a fundamental factor in order to almost rationally build the social-political-legal life and, at the same time, as a potential disruptive factor of the polis. Within the Homeric world some relevant tracks of this complex model emerge, especially in the light of two elements closely related to each other: the political-representative role played by the primitive forms of agora and the institution of the ‘duel’, which is to be regarded as a crucial legalpolitical tool to control the emotive dimension in the archaic world. Anyway only tragedy, through a reinterpretation of myth, offers relevant examples of the ambiguous role played by emotion within the polis: both as a building factor of the public space, closely related to the public function of tragedy, and as a disruptive force (with particular regard to the female dimension: for instance Medea and Electra). According to a very significant continuity literature-philosophy, Aristotle synthesizes in a more specifically political-legal direction this complex tradition: similarly to the Platonic perspective, within Aristotle’s model polis

Abstract

Purpose: Epicardial adipose tissue (EAT) thickness, measured by echocardiography, is associated to the presence of coronary artery disease (CAD) and severe aortic stenosis (AS). EAT thickness is commonly referred as the diameter of the echo-free space between the right ventricular wall and the visceral layer of the pericardium in parasternal long axis view, using the aortic annulus as an anatomic landmark (EAT-1). We aimed to demonstrate that the direct measurement of the adipose tissue thickness visualized in the space between the ascending aorta and the right ventricle (EAT-2) might be considered an alternative method. Methods: We measured EAT-1 and EAT-2 in 130 pts with severe cardiac disease referred for cardiac surgery: 53 pts with isolated AS, 49 pts with severe CAD, and 28 pts with both severe AS and CAD (AS+CAD); and in 50 control subjects matched for age, sex and BMI. The two measurements were obtained at end-systole in 3 cardiac cycles (figure). Results. Both EAT-1 and EAT-2 measurements had an excellent reproducibility. With respect to controls pts had significantly increased EAT-1 (2,4 ± 0,5mm vs 6 ± 2mm; p<0,05) and EAT-2 (3 ± 1,2mm vs 12 ± 3mm; p<0,05). EAT-1 and EAT-2 were not statistically different in controls. EAT-2 was significantly higher than EAT-1 in CAD, AS, and AS+CAD pts (p<0,05). Interestingly, EAT-2, but not EAT-1, was significantly increased in AS+CAD pts with respect to EAT-2 of pts with isolated AS and isolated CAD. Conclusions: Our data demonstrate that EAT-2, as well as EAT-1, is a valuable method to measure EAT thickness. Further, EAT-2 seems to better recognize EAT increase, in pts with AS+CAD. Comprehensively, EAT-2 is greater than EAT-1. The larger space between ascending aorta and right ventricle, allowing EAT expansion, could justify our observation.

Abstract

Purpose: We have previously demonstrated that multi-line transmit (MLT) beam forming can provide high quality full field-of-view (90° sector) B-mode images at very high frame rates, i.e. up to 500 fps. The purpose of this study was to test the feasibility of this technique in imaging the mechanical intraventricular waves such as the one associated with activation of the left ventricle. Methods: A dedicated pulse sequence using MLT was implemented on the ULA-OP research scanner equipped with a 2.0 MHz phased array to obtain 90° sector images at a frame rate of 436 fps. The left ventricle of a healthy volunteer was imaged from the apical 4 chamber view and the RF data was acquired. Subsequently, the strain rate was extracted from the RF data using a normalized cross-correlation method. Results: As expected, during the early filling phase, myocardium lengthening (positive strain rate) was observed propagating from the base of the septum to the apex and back (Figure a). A similar wave was detected in the lateral wall, although a brief shortening (negative strain rate) was detected in the mid-wall which could be the result of reverberations (Figure b). During isovolumetric contraction, the septal wall shortened before the lateral wall (as expected) - moreover - there seemed to be an intra-wall base-apex shortening gradient (Figure c and d). Conclusions: Our preliminary results show that visualization of the cardiac mechanical activation could be feasible using MLT based high frame rate imaging. Further research is required to examine this in depth, which is the topic of on-going work. Figure Curved M-mode of strain rate

Abstract

An 89–year-old woman experienced sudden dyspnea and chest pain 3 days after total hip replacement surgery. Electrocardiography revealed sinus tachycardia and T-wave inversion in leads III, aVF and V1 through V4. The patient had a slightly elevated troponin T level. Echocardiography showed right ventricular (RV) enlargement and akinesis of the RV free wall, with preserved wall motion of the RV apex. Left ventricular wall motion was preserved. Cardiac magnetic resonance imaging also showed the wall motion abnormality to be localized in the free wall of the RV. Late gadolinium enhancement was absent in both left ventricular and the RV wall. Pulmonary embolism and coronary artery disease as a cause of the RV wall motion abnormality were excluded by a contrast enhanced multi-detector computed tomography scan. She was diagnosed as an isolated RV TakoTsubo cardiomyopathy (TC) and was conservatively managed. On postoperative day 11, follow-up echocardiography showed improvement in wall motion of the RV. Although TC was first recognized as LV apical ballooning induced by emotional and/or physical stress, TC with RV involvement has been reported as a possible variant in about one-fourth patients with TC. In our present case, isolated RV wall motion abnormality was clearly documented by both echocardiography and cardiac magnetic resonance imaging. Thus, isolated RV TC may be a new, emerging variant of TC. Figure

Abstract

Purpose: Although delayed-enhancement magnetic resonance imaging (DEMRI) is essential for diagnosis of cardiac sarcoidosis (CS), the test was not available when pacemaker was implamted. Recently, MR-conditional pacemaker has become avilable and we hypothesized that this device would be useful for diagnosis and management of CS. The aim of this study was to assess the diagnostic ability of MR-conditional pacemaker about CS in patients with advanced A-V nodal block (AAVB). Methods: Twenty-seven AAVB patients (14 men, 13 women; mean age, 69 ± 11 years) who were implanted MR-conditional pacemaker were studied. DEMRI was performed 6 weeks after implantation of permanent pacemaker. In patients with positive for DE, additional examinations like echocardiography, radioisotope imaging, biopsy, and coronary computed-tomography were performed due to confirm the diagnosis of CS and exclude coronary artery disease. Results: DE was observed in 12 patients (44 %). Out of 12 patients, 2 patients were excluded for having prior myocardial infarction. Seven of 10 (70 %) patients were diagnosed of CS by the consensus criteria. Compared with non-CS group, CS group had significantly lower age (61 ± 12 years vs. 72 ± 9 years p = 0.017). There was no significant difference about sex, angiotensin-converting enzyme, brain natriuretic peptide, and left ventricular ejection fraction between 2 groups. Six patients had started corticosteroid therapy and 5 patients (83%) recovered A-V nodal conduction. Conclusion: MR-conditional pacemaker was useful for diagnosis and management of patients with AAVB caused by CS. Figure Cardiac MRI in patient with AV block

Abstract

Objective:  We aimed to investigate the reproducibility of vena contracta (VC) in mitral regurgitation (MR) of different etiology between an inexperienced and an experienced echocardiographer. Background: MR is the second most common valvular heart disease in Europe that requires surgery.  Echocardiography is the principal modality of investigation when MR is suspected. In European and American guidelines VC is described as one of the most feasible echocardiographic measurements in the assessment of MR. There is a lack of publications regarding intra-observer variability and studies comparing inexperienced and experienced echocardiographers for the assessment of VC. Method/Material: VC of 55 recorded 2D echocardiograms with known MR of different degree and etiology were analyzed from parasternal long axis view, 4- and 3 chamber view. The mean value of the different plane measurements of each exam was used for statistical analysis. Analyses were made by an inexperienced (A) fellow echocardiographer (<100 studies) and a level 3 experienced (B) echocardiographer. Measurements of VC by the 2 echocardiographers were performed blinded to clinical data. Measurements were performed with at least 2 weeks apart, blinded to the first measurement. Results: Three exams were excluded (feasibility 95%) from statistical analysis because adequate color Doppler images from all tree planes was not available. The inter class correlation (ICC) between the first and second analysis was (r=0.75; 95% CI -1.1 to 1.7mm) for A and (r=0.94; 95% CI -0.76 to 0.84mm) for B. There was good ICC between the 2 echocardiographers (r=0.78; 95% CI -1.5 to 1.3mm). The intra observer variability was 11.1% for A and 6.1% for B. The inter observer variability was 11.7% (p>0.05 for all). Conclusion: Measurement of vena contracta in mitral regurgitation is a feasible semi-quantitative parameter. Good correlation and narrow limits of agreement between a novice and an experienced echocardiographer was demonstrated in our study.

Abstract

An 83-year-old morbid woman presented with progredient dyspnoea (New York Heart Association [NYHA] stage IV) and a history of recurrent pulmonary oedema. Owing to type A aortic disection, she underwent aortic surgery 3 years prior (January 2009), which included supracoronary ascending aortic replacement and a proximal aorta-to-prosthesis anastomosis. Transthoracic echocardiography revealed major pulmonary hypertension with an estimated systolic pulmonary pressure of 70-75 mm Hg and severe tricuspid regurgitation. Further investigation, including computed tomography and 3-D transoesophageal echocardiography, revealed rupture of the aortic prothesis with a fistula of the paraprosthetic lumen to the right pulmonary artery. Because of multiple concomitant diseases and severe right-sided heart failure, an interventional approach was initiated. With a complex 3-D-echo-guided intervention, the fistula was successfully closed using a 12-mm Amplatzer ASD Occluder which resulted in a reduction in shunt volume. Postinterventional imaging showed the correct position of the occluder with only a minor residual flow. At 18 months' follow-up, the patient presented with improvement of the preexisting dyspnoea, from NYHA stage IV to NYHA stage II or III. The cardiac ultrasound result indicated a reduction in estimated systolic pulmonary pressure to 45-50 mm Hg. Figure

34. Renal Cell Carcinoma in Pregnancy: A Case Report of a Rare Diagnosis.

Author

Ferreira B, Alves AR, and Rodrigues AC

Abstract

Renal cell carcinoma is rarely reported in pregnant women. Diagnosis is often delayed because symptoms are similar to physiological changes and disorders of pregnancy. Each case should be discussed on an individual basis because there are no guidelines described for the clinical management of this disease during pregnancy. We report the case of a 37-year-old woman who presented to the emergency department at six weeks of gestation with left-sided flank pain and pollakiuria. Renal ultrasound revealed a 6 cm solid mass in the left kidney, suggestive of a renal neoplasm. Magnetic resonance imaging showed no signs of local or distant metastasis. The patient was treated with laparoscopic radical nephrectomy at 14 weeks of gestation without any complications. Histopathology confirmed the diagnosis of a renal clear-cell carcinoma. Progression of pregnancy was normal, and the patient gave birth to a healthy child at term. Follow-up examinations after four years demonstrated no cancer recurrence., Competing Interests: Human subjects: Consent for treatment and open access publication was obtained or waived by all participants in this study.

Abstract

This study purposes three triazine-based porous organic polymers (T-POPs 1-3) as advanced platforms for the early detection of antibiotic-polluted environments and effective water decontamination, in order to mitigate water pollution and antimicrobial resistance, which are two huge current problems damaging ecosystems and human health. T-POPs exhibited good performances as adsorbents for the removal of sulfamethazine (SMT) and tetracycline (TC) from water, with efficiencies up to 97% and 96%, and maximum adsorption capacities between (0.36-0.44) and (0.21-0.27) mmol g -1 , respectively, which are similar or even higher (up to 40.3 times) than those reported for other materials. In addition, good reusability was achieved, particularly for T-POP2, despite being the polymer with the lowest surface area. A slightly higher selectivity of T-POPs for sulfonamides and the best performance of T-POP3 to remove six antibiotics from a micromolar solution were observed. T-POPs also acted as fluorescent chemosensors, since T-POP1 underwent linear Stern-Volmer fluorescence quenching in the presence of both SMT and TC, while the enhanced-fluorescent T-POP2 and T-POP3 experienced fluorescence extinction through a sphere of action mechanism in contact with TC, and bathochromic shift accompanied by a hyperchromic effect on the new fluorescent region with the increase in SMT concentration. Thus, T-POP2 and T-POP3 can both promote a selective on-site monitoring of each drug in contaminated water streams and an efficient water remediation, thanks to the synergy between hydrogen and van der Waals interactions. In summary, these triazine-based porous organic polymers are promising materials for the simultaneous monitoring and treatment of antibiotic-containing water and wastewaters., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests:Ana Clara B.

Abstract

Human papillomavirus (HPV) infection is implicated in causing several types of cancer, including cervical cancer. In Brazil, the quadrivalent HPV vaccine is provided free of charge for children between the ages of 9 and 14. Nevertheless, the vaccination coverage rate has remained below 60% since its implementation in 2014. This study aimed (i) to assess the knowledge of parents/guardians on HPV infection and vaccine prophylaxis and (ii) to test the association between having a "higher degree of knowledge" (HDK) and the sociodemographic characteristics. A total of 388 parents/guardians of children of vaccination age were enrolled. Questions assessing sociodemographic characteristics, knowledge, and attitudes toward HPV infection and vaccination were administered to participants via a self-answered questionnaire. Questionnaires of 343 participants were considered for analysis. Participants who answered at least 70% of the questions correctly were classified as presenting HDK. Multivariate logistic regression analysis was used to calculate odds ratios (ORs) and 95% confidence intervals (95% CIs) for the associations between population characteristics and HDK. This study occurred prior to the COVID-19 pandemic; thus, the pandemic was not considered in our analysis. A total of 212 (61.8%) participants showed HDK. Participants who were male (OR = 0.39; 95% CI = 0.22, 0.70) and lived in larger households (OR = 0.48; 95% CI = 0.25, 0.95) were less likely to present HDK. Participants who reported having an acquaintance with prior/concurrent HPV infection were more likely to have HDK (OR = 3.78; 95% CI = 2.02, 7.05). These findings suggest the importance of developing novel strategies for raising parental awareness of HPV, particularly targeting males., Competing Interests: Declarations Competing Interests The authors declare no competing interests., (© 2024.

Abstract

Aging is associated with decreased health span, and despite the recent advances made in understanding the mechanisms of aging, no antiaging drug has been approved for therapy. Therefore, strategies to promote a healthy life in aging are desirable. Previous work has shown that chronic treatment with extracellular vesicles (EVs) from young mice prolongs lifespan in old mice, but the mechanism of action of this effect on liver metabolism is not known. Here we investigated the role of treatment with EVs derived from young sedentary (EV-C) or exercised (EV-EX) mice in the metabolism of old mice and aimed to identify key youthful-associated microRNA (miRNA) cargos that could promote healthy liver function. We found that aged mice treated with either EV-C or EV-EX had higher insulin sensitivity, higher locomotor activity resulting in longer distance traveled in the cage, and a lower respiratory exchange ratio compared to mice treated with EVs from aged mice (EV-A). In the liver, treatment with young-derived EVs reduced aging-induced liver fibrosis. We identified miR-30c in the EVs as a possible youth-associated miRNA as its level was higher in circulating EVs of young mice. Treatment of aged mice with EVs transfected with miR-30c mimic reduced stellate cell activation in the liver and reduced fibrosis compared to EV-negative control by targeting Foxo3. Our results suggest that by delivering juvenile EVs to old mice, we can improve their liver health. Moreover, we identified miR-30c as a candidate for antiaging liver therapy., (© 2024 The Author(s).

Abstract

Objective. This study proposes a closed-loop brain-machine interface (BMI) based on spinal cord stimulation to inhibit epileptic seizures, applying a semi-supervised machine learning approach that learns from Local Field Potential (LFP) patterns acquired on the pre-ictal (preceding the seizure) condition. Approach. LFP epochs from the hippocampus and motor cortex are band-pass filtered from 1 to 13 Hz, to obtain the time-frequency representation using the continuous Wavelet transform, and successively calculate the phase lock values (PLV). As a novelty, the Z -score-based PLV normalization using both modified k -means and Davies-Bouldin's measure for clustering is proposed here. Consequently, a generic seizure's detector is calibrated for detecting seizures on the normalized PLV, and enables the spinal cord stimulation for periods of 30 s in a closed-loop, while the BMI system detects seizure events. To calibrate the proposed BMI, a dataset with LFP signals recorded on five Wistar rats during basal state and epileptic crisis was used. The epileptic crisis was induced by injecting pentylenetetrazol (PTZ). Afterwards, two experiments without/with our BMI were carried out, inducing epileptic crisis by PTZ in Wistar rats. Main results. Stronger seizure events of high LFP amplitudes and long time periods were observed in the rat, when the BMI system was not used. In contrast, short-time seizure events of relative low intensity were observed in the rat, using the proposed BMI. The proposed system detected on unseen data the synchronized seizure activity in the hippocampus and motor cortex, provided stimulation appropriately, and consequently decreased seizure symptoms. Significance. Low-frequency LFP signals from the hippocampus and motor cortex, and cord spinal stimulation can be used to develop accurate closed-loop BMIs for early epileptic seizures inhibition, as an alternative treatment., (© 2024 IOP Publishing Ltd.

39. Intraductal Papillary Neoplasm of the Bile Duct Mimicking a Cholangiocarcinoma.

Author

Couto J Sr, Martins A, Mendes J, and Rodrigues AC

Abstract

The intraductal papillary neoplasm of the bile duct is a rare tumor considered one of the precursor lesions of cholangiocarcinoma. It is characterized by papillary growth within the bile duct lumen, occurring anywhere in the biliary tree. We report a case of a 70-year-old man who presented with a six-month history of weight loss and occasional choluria. An abdominal ultrasound showed a marked dilatation of the biliary tree with a polypoid intraluminal lesion. Computed tomography and magnetic resonance imaging confirmed the presence of these findings and did not reveal any secondary lesions. The patient underwent a cephalic duodenopancreatectomy yielding a diagnosis of intraductal papillary neoplasm with high-grade dysplasia., Competing Interests: Human subjects: Consent for treatment and open access publication was obtained or waived by all participants in this study.

Abstract

Abnormal patterns of brain connectivity characterize epilepsy. However, little is known about these patterns during the stages preceding a seizure induced by pentylenetetrazol (PTZ). To investigate brain connectivity in male Wistar rats during the preictal phase of PTZ-induced seizures (60 mg/kg), we recorded local field potentials in the primary motor (M1) cortex, the ventral anterior (VA) nucleus of the thalamus, the hippocampal CA1 area, and the dentate gyrus (DG) during the baseline period and after PTZ administration. While there were no changes in power density between the baseline and preictal periods, we observed an increase in directional functional connectivity in theta from the hippocampal formation to M1 and VA, as well as in middle gamma from DG to CA1 and from CA1 to M1, and also in slow gamma from M1 to CA1. These findings are supported by increased phase coherence between DG-M1 in theta and CA1-M1 in middle gamma, as well as enhanced phase-amplitude coupling of delta-middle gamma in M1 and delta-fast gamma in CA1. Interestingly, we also noted a slight decrease in phase synchrony between CA1 and VA in slow gamma. Together, these results demonstrate increased functional connectivity between brain regions during the PTZ-induced preictal period, with this increase being particularly driven by the hippocampal formation., 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 © 2024 Elsevier B.V.

Abstract

Bacterial cellulose (BC) has a long-standing human consumption history in different geographies without any report of adverse effects. Despite its unique textural and functional properties, the use of BC in food products in Europe is still restricted due to concerns over its nanosize. Here, we evaluated the potential uptake of celluloses (from plant and microbial sources, processed using different blenders) by macrophages (differentiated THP-1 cells) and human intestinal epithelial cells (Caco-2 and HT29-MTX cells) without (coculture) or with (triculture) Raji-B cells. A carbohydrate-binding module coupled to a green fluorescent protein was employed to observe cellulose in the cell cultures by confocal laser scanning microscopy and stimulated emission depletion microscopy. The methodology demonstrated excellent sensitivity, allowing detection of single nanocrystals within cells. All celluloses were taken up by the macrophages, without significantly compromising the cell's metabolic viability. The viability of the cocultures was also not affected. Furthermore, no internalization was observed in the triculture cell model that was exposed 24 h to BC and Avicel LM310. When (rarely) detected, cellulose particles were found on the apical side of the membrane. Overall, the obtained results suggest that BC should not be absorbed into the human gut.

Abstract

Integrating agricultural, chemical, and technological knowledge is crucial for developing bio-nanotechnologies to improve agricultural production. This study explores the innovative use of biopolymeric coatings, based on sodium alginate and sodium alginate + Laponite® (nanoclay), containing biostimulants (tryptophol and thymol) or not, on garlic cloves. These coatings were analyzed using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR-ATR), and scanning electron microscopy (SEM). Greenhouse bioassays showed improvements in garlic shoot plant biomass with both treatments: sodium alginate biopolymer and sodium alginate biopolymer plus Laponite®. In the field experiment, garlic plants treated with sodium alginate, in combination with conventional pesticide treatments, resulted in better quality garlic bulbs, where larger garlics were harvested in this treatment, reducing commercial losses. In tropical garlic crops, obtaining plants with greater initial vigor is essential. Our results highlight the potential of these bio-nanotechnological strategies to enhance garlic propagation, ensuring environmental protection and food security., 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 © 2024 Elsevier Masson SAS.

Abstract

This study assessed the monotonic and fatigue flexural strength (FS), elastic modulus (E), and surface characteristics of a 3D printed zirconia-containing resin composite compared to subtractive and conventional layering methods. Specimens, including discs (n = 15; Ø = 15 mm × 1.2 mm) and bars (n = 15; 14 × 4 × 1.2 mm), were prepared and categorized into three groups: 3D printing (3D printing - PriZma 3D Bio Crown, Makertech), Subtractive (Lava Ultimate blocks, 3M), and Layering (Filtek Z350 XT, 3M). Monotonic tests were performed on the discs using a piston-on-three-balls setup, while fatigue tests employed similar parameters with a frequency of 10 Hz, initial stress at 20 MPa, and stress increments every 5000 cycles. The E was determined through three-point-bending test using bars. Surface roughness, fractographic, and topographic analyses were conducted. Statistical analyses included One-way ANOVA for monotonic FS and roughness, Kruskal-Wallis for E, and Kaplan-Meier with post-hoc Mantel-Cox and Weibull analysis for fatigue strength. Results revealed higher monotonic strength in the Subtractive group compared to 3D printing (p = 0.02) and Layering (p = 0.04), while 3D Printing and Layering exhibited similarities (p = 0.88). Fatigue data indicated significant differences across all groups (3D Printing < Layering < Subtractive; p = 0.00 and p = 0.04, respectively). Mechanical reliability was comparable across groups. 3D printing and Subtractive demonstrated similar E, both surpassing Layering. Moreover, 3D printing exhibited higher surface roughness than Subtractive and Layering (p < 0.05). Fractographic analysis indicated that fractures initiated at surface defects located in the area subjected to tensile stress concentration. A porous surface was observed in the 3D Printing group and a more compact surface in Subtractive and Layering methods. This study distinguishes the unique properties of 3D printed resin when compared to conventional layering and subtractive methods for resin-based materials. 3D printed shows comparable monotonic strength to layering but lags behind in fatigue strength, with subtractive resin demonstrating superior performance. Both 3D printed and subtractive exhibit similar elastic moduli, surpassing layering. However, 3D printed resin displays higher surface roughness compared to subtractive and layering methods. The study suggests a need for improvement in the mechanical performance of 3D printed material., 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 © 2024 Elsevier Ltd.

Abstract

Chronic and excessive glucocorticoid (GC) exposure can cause Cushing's syndrome, resulting in fat accumulation in selected body areas. Particularly in the brown adipose tissue (BAT), GC acts negatively, resulting in whitening of the tissue. We hypothesized that dysregulation of microRNAs by GC could be an additional mechanism to explain its negative actions in BAT. Male Wistar rats were divided into two groups: (1) Control sham and (2) GC group that was administered dexamethasone 6.25 mg/200 μL via osmotic pump implantation over 28 days. After this period, the animals were euthanized and BAT tissue was properly stored. Human fat cells treated with dexamethasone were used to translate the experimental results found in animals to human biology. GC-treated rat BAT presented with large lipid droplets, severely impaired thermogenic activation, and reduced glucose uptake measured by 18 F-FDG PET/CT. GC exposure induced a reduction in the mitochondrial OXPHOS system and oxygen consumption. MicroRNA profiling of BAT revealed five top-regulated microRNAs and among them miR-21-5p was the most significantly upregulated in GC-treated rats compared to the control group. Although upregulation of miR-21-5p in the tissue, differentiated primary brown adipocytes from GC-treated rats had decreased miR-21-5p levels compared to the control group. To translate these results to the clinic, human brown adipocytes were treated with dexamethasone and miR-21-5p inhibitor. In human brown cells, inhibition of miR-21-5p increased brown adipocyte differentiation and prevented GC-induced glucose uptake, resulting in a lower glycolysis rate. In conclusion, high-dose GC therapy significantly impacts brown adipose tissue function, with a notable association between glucose uptake and miR-21-5p., (© 2024 Wiley Periodicals LLC.)

Abstract

Cellular compartmentalization, achieved through membrane-based compartments, is a fundamental aspect of cell biology that contributes to the evolutionary success of cells. While organelles have traditionally been the focus of research, membrane-less organelles (MLOs) are emerging as critical players, exhibiting distinct morphological features and unique molecular compositions. Recent research highlights the pivotal role of long noncoding RNAs (lncRNAs) in MLOs and their involvement in various cellular processes across different organisms. In the context of cancer, dysregulation of MLO formation, influenced by altered lncRNA expression, impacts chromatin organization, oncogenic transcription, signaling pathways, and telomere lengthening. This review synthesizes the current understanding of lncRNA composition within MLOs, delineating their functions and exploring how their dysregulation contributes to human cancers. Environmental challenges in tumorigenesis, such as nutrient deprivation and hypoxia, induce stress granules, promoting cancer cell survival and progression. Advancements in biochemical techniques, particularly single RNA imaging methods, offer valuable tools for studying RNA functions within live cells. However, detecting low-abundance lncRNAs remains challenging due to their limited expression levels. The correlation between lncRNA expression and pathological conditions, particularly cancer, should be explored, emphasizing the importance of single-cell studies for precise biomarker identification and the development of personalized therapeutic strategies.

Abstract

Objective: The cortico-basal ganglia circuit is crucial to understanding locomotor behavior and movement disorders. Spinal cord stimulation modulates that circuit, which is a promising approach to restoring motor functions. However, the effects of electrical spinal cord stimulation in the healthy brain motor circuit in pre- and postgait are poorly understood. Thus, this report aims to evaluate, through electrophysiological analyses, the dynamic spectral features of motor networks underlying locomotor initiation with spinal cord stimulation., Materials and Methods: Wistar male rats underwent spinal cord stimulation (current 30-150 μA, frequency 100, 333, and 500 Hz) with the electrophysiological recording of the caudate and putamen nuclei, primary and secondary motor cortices, and primary somatosensory cortex. Video tracking recorded treadmill locomotion and extracted the motor planning and gait initiation., Results: Spectral analysis of segments of gait initiation (pre- and postgait), with stimulation off, showed increased low-frequency activity. Postgait initiation showed increased alpha and beta rhythms and decreased delta rhythm with the stimulation off. Overall, the stimulation frequencies reduced alpha and beta rhythms in all brain areas during movement initiation. Regarding movement planning, such an effect was observed in the sensorimotor area, comprising the delta and alpha rhythms., Conclusion: This study showed a short-term effect of spinal cord stimulation on the brain areas of the motor circuit, suggesting possible facilitation of movement planning and starting through neuromodulation. Thus, the electrophysiological characterization of this study may contribute to understanding basal ganglia networks and developing new approaches to treat movement disorders in the gait initiation phase., Competing Interests: Conflict of Interest The authors reported no conflict of interest., (Copyright © 2024 International Neuromodulation Society.

Abstract

The most common form of hypercortisolism is iatrogenic Cushing's syndrome. Lipodystrophy and metabolic disorders can result from the use of exogenous glucocorticoids (GC). Adipocytes play an important role in the production of circulating exosomal microRNAs, and knockdown of Dicer promotes lipodystrophy. The aim of this study is to investigate the effect of GCs on epididymal fat and to assess their influence on circulating microRNAs associated with fat turnover. The data indicate that despite the reduction in adipocyte volume due to increased lipolysis and apoptosis, there is no difference in tissue mass, suggesting that epididymal fat pad, related to animal size, is not affected by GC treatment. Although high concentrations of GC have no direct effect on epididymal microRNA-150-5p expression, GC can induce epididymal adipocyte uptake of microRNA-150-5p, which regulates transcription factor Ppar gamma during adipocyte maturation. In addition, GC treatment increased lipolysis and decreased glucose-derived lipid and glycerol incorporation. In conclusion, the similar control and GC epididymal fat mass results from increased dense fibrogenic tissue and decreased adipocyte volume induced by the lipolytic effect of GC. These findings demonstrate the complexity of epididymal fat. They also highlight how this disease alters fat distribution. This study is the first in a series published by our laboratory showing the detailed mechanism of adipocyte turnover in this disease., 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 © 2024 Elsevier B.V.

Abstract

Purpose: Frailty is an independent risk factor for adverse postoperative outcomes following intracranial meningioma resection (IMR). The role of the Risk Analysis Index (RAI) in predicting postoperative outcomes following IMR is nascent but may inform preoperative patient selection and surgical planning., Methods: IMR patients from the Nationwide Inpatient Sample were identified using diagnostic and procedural codes (2019-2020). The relationship between preoperative RAI-measured frailty and primary outcomes (non-home discharge (NHD), in-hospital mortality) and secondary outcomes (extended length of stay (eLOS), complication rates) was assessed via multivariate analyses. The discriminatory accuracy of the RAI for primary outcomes was measured in area under the receiver operating characteristic (AUROC) curve analysis., Results: A total of 23,230 IMR patients (mean age = 59) were identified, with frailty statuses stratified by RAI score: 0-20 "robust" (R)(N = 10,665, 45.9%), 21-30 "normal" (N)(N = 8,895, 38.3%), 31-40 "frail" (F)(N = 2,605, 11.2%), and 41+ "very frail" (VF)(N = 1,065, 4.6%). Rates of NHD (R 11.5%, N 29.7%, F 60.8%, VF 61.5%), in-hospital mortality (R 0.5%, N 1.8%, F 3.8%, VF 7.0%), eLOS (R 13.2%, N 21.5%, F 40.9%, VF 46.0%), and complications (R 7.5%, N 11.6%, F 15.7%, VF 16.0%) significantly increased with increasing frailty thresholds (p < 0.001). The RAI demonstrated strong discrimination for NHD (C-statistic: 0.755) and in-hospital mortality (C-statistic: 0.754) in AUROC curve analysis., Conclusion: Increasing RAI-measured frailty is significantly associated with increased complication rates, eLOS, NHD, and in-hospital mortality following IMR. The RAI demonstrates strong discrimination for predicting NHD and in-hospital mortality following IMR, and may aid in preoperative risk stratification., (© 2024.

Abstract

The filamentous bacteriophage M13KO7 (M13) is the most used in phage display (PD) technology and, like other phages, has been applied in several areas of medicine, agriculture, and in the food industry. One of the advantages is that they can modulate the immune response in the presence of pathogenic microorganisms, such as bacteria and viruses. This study evaluated the use of phage M13 in the chicken embryos model. We inoculated 13-day-old chicken embryos with Salmonella Pullorum (SP) and then evaluated survival for the presence of phage M13 or E. coli ER2738 (ECR) infected with M13. We found that the ECR bacterium inhibits SP multiplication in 0.32 (M13-infected ECR) or 0.44 log UFC/mL (M13-uninfected ECR) and that the ECR-free phage M13 from the PD library can be used in chicken embryo models. This work provides the use of the chicken embryo as a model to study systemic infection and can be employed as an analysis tool for various peptides that M13 can express from PD selection. KEY POINTS: • SP-infected chicken embryo can be a helpful model of systemic infection for different tests. • Phage M13 does not lead to embryonic mortality or cause serious injury to embryos. • Phage M13 from the PD library can be used in chicken embryo model tests., (© 2024.

Abstract

Diisopentyl phthalate (DiPeP) is primarily used as a plasticizer or additive within the production of polyvinyl chloride (PVC), and has many additional industrial applications. Its metabolites were recently found in urinary samples of pregnant women; thus, this substance is of concern as relates to human exposure. Depending upon the nature of the alcohol used in its synthesis, DiPeP may exist either as a mixture consisting of several branched positional isomers, or as a single defined structure. This article investigates the skin sensitization potential and immunomodulatory effects of DiPeP CAS No. 84777-06-0, which is currently marketed and classified as a UVCB substance, by in silico and in vitro methods. Our findings showed an immunomodulatory effect for DiPeP in LPS-induced THP-1 activation assay (increased CD54 expression). In silico predictions using QSAR TOOLBOX 4.5, ToxTree, and VEGA did not identify DiPeP, in the form of a discrete compound, as a skin sensitizer. The keratinocyte activation (Key Event 2 (KE2) of the adverse outcome pathway (AOP) for skin sensitization) was evaluated by two different test methods (HaCaT assay and RHE assay), and results were discordant. While the HaCaT assay showed that DiPeP can activate keratinocytes (increased levels of IL-6, IL-8, IL-1α, and ILA gene expression), in the RHE assay, DiPeP slightly increased IL-6 release. Although inconclusive for KE2, the role of DiPeP in KE3 (dendritic cell activation) was demonstrated by the increased levels of CD54 and IL-8 and TNF-α in THP-1 cells (THP-1 activation assay). Altogether, findings were inconclusive regarding the skin sensitization potential of the UVCB DiPeP-disagreeing with the results of DiPeP in the form of discrete compound (skin sensitizer by the LLNA assay). Additional studies are needed to elucidate the differences between DiPeP isomer forms, and to better understand the applicability domains of non-animal methods in identifying skin sensitization hazards of UVCB substances., (© 2024.
