Abstract The connection between triglyceride-rich lipoproteins and cardiometabolic multimorbidity, characterized by the concurrence of at least two of type 2 diabetes, ischemic heart disease, and stroke, has not been definitively established. We aim to examine the prospective associations between serum remnant cholesterol, triglycerides, and the risks of progression from first cardiometabolic disease to multimorbidity via multistate modeling in the UK Biobank. We also evaluate the causality of these associations via Mendelian randomization using 13 biologically relevant SNPs as the genetic instruments. Here we show that elevated remnant cholesterol and triglycerides are significantly associated with gradually higher risks of cardiometabolic multimorbidity, particularly the progression of ischemic heart disease to the multimorbidity of ischemic heart disease and type 2 diabetes. These results advocate for effective management of remnant cholesterol and triglycerides as a potential strategy in mitigating the risks of cardiometabolic multimorbidity.

This study reviews the recent advances in data-driven polarimetric imaging technologies based on a wide range of practical applications. The widespread international research and activity in polarimetric imaging techniques demonstrate their broad applications and interest. Polarization information is increasingly incorporated into convolutional neural networks (CNN) as a supplemental feature of objects to improve performance in computer vision task applications. Polarimetric imaging and deep learning can extract abundant information to address various challenges. Therefore, this article briefly reviews recent developments in data-driven polarimetric imaging, including polarimetric descattering, 3D imaging, reflection removal, target detection, and biomedical imaging. Furthermore, we synthetically analyze the input, datasets, and loss functions and list the existing datasets and loss functions with an evaluation of their advantages and disadvantages. We also highlight the significance of data-driven polarimetric imaging in future research and development.

Abstract Organic heterostructures (OHTs) with the desired geometry organization on micro/nanoscale have undergone rapid progress in nanoscience and nanotechnology. However, it is a significant challenge to elucidate the epitaxial-growth process for various OHTs composed of organic units with a lattice mismatching ratio of > 3%, which is unimaginable for inorganic heterostructures. Herein, we have demonstrated a vivid visualization of the morphology evolution of epitaxial-growth based on a doped interfacial-layer, which facilitates the comprehensive understanding of the hierarchical self-assembly of core-shell OHT with precise spatial configuration. Significantly, the barcoded OHT with periodic shells obviously illustrate the shell epitaxial-growth from tips to center parts along the seeded rods for forming the core-shell OHT. Furthermore, the diameter, length, and number of periodic shells were modulated by finely tuning the stoichiometric ratio, crystalline time, and temperature, respectively. This epitaxial-growth process could be generalized to organic systems with facile chemical/structural compatibility for forming the desired OHTs.

Abstract Background Vulvar and vaginal melanoma (VuM & VaM) is a rare gynecologic malignancy with high mortality but low effectiveness to checkpoint immunotherapy compared to cutaneous melanoma. This article aims to elucidate the role of the disordered immune microenvironment in cancer progression in VuM. Methods At first, this article applied single-cell RNA sequencing (scRNA-seq) to the VuM obtained from a 68-year-old female patient, and constructed a single-cell atlas of VuM consist of 12,243 single cells. Then this article explores the genomic complexity and core signal channel in VuM microenvironment. Results This article provides new insights about the pathogenesis of VuM based on single-cell resolution data. It was found that the activation of CD8+ T cell contributed to induce tumor angiogenesis and immune escape, and the activation of the antigen-presenting molecular function participated in melanoma metastasis. Conclusion This article provided new insights into underlining VuM molecular regulation and potential signaling involved in immunotherapy, which would benefit the clinical practice and administration.

Objective: Whether to continue administering immunotherapy to patients with advanced non-small cell lung cancer (NSCLC) who have experienced tumor progression remains controversial after immunotherapy. The aims were to explore survival outcomes after further immunotherapy post-progression and to determine the optimal combination therapy in such cases. Methods: Overall, 507 patients with NSCLC who underwent immunotherapy and experienced tumor progression were retrospectively divided into Immuno-combination and No-immuno groups according to whether additional combination therapy involving immunotherapy was administered post-progression. Progression-free survival (PFS) and overall survival (OS) were evaluated. Subgroup analyses were performed according to the different treatment regimens for patients in the Immuno-combination group. Results: After propensity score matching, there were 150 patients in the No-immuno group and 300 patients in the Immuno combination group. Superior PFS was observed in the Immuno-combination group compared with those in the No-immuno group (6-month PFS: 25.3 % vs. 60.6 %; 12-month PFS: 6.7 % vs. 24.4 %; P < 0.001). Similar intergroup differences were observed for OS (12-month OS: 22.3 % vs. 69.4 %; 18-month OS: 6.4 % vs. 40.4 %; P < 0.001). Superior PFS outcomes were observed in the Immuno+Antiangiogenic group compared with the Immuno+Chemo group (6-month PFS: 51.3 % vs. 71.5 %; 12-month PFS: 23.1 % vs. 25.7 %; P = 0.017). Similar differences in OS were observed between those same subgroups (12-month OS: 62.1 % vs. 77.9 %; 18-month OS: 33.3 % vs. 48.7 %; P = 0.006). Conclusion: Patients with NSCLC experiencing tumor progression post-immunotherapy can still benefit from further treatment, with immunotherapy combined with antiangiogenic therapy the most efficacious option.

Objective: To investigate the effects of repeated vaccination with ancestral SARS-CoV-2 (Wuhan-hu-1)-based inactivated, recombinant protein subunit or vector-based vaccines on the neutralizing antibody response to Omicron subvariants. Methods: Individuals who received four-dose vaccinations with the Wuhan-hu-1 strain, individuals who were infected with the BA.5 variant alone without prior vaccination, and individuals who experienced a BA.5 breakthrough infection (BTI) following receiving 2-4 doses of the Wuhan-hu-1 vaccine were enrolled. Neutralizing antibodies against D614G, BA.5, XBB.1.5, EG.5.1, and BA.2.86 were detected using a pseudovirus-based neutralization assay. Antigenic cartography was used to analyze cross-reactivity patterns among D614G, BA.5, XBB.1.5, EG.5.1, and BA.2.86 and sera from individuals. Results: The highest neutralizing antibody titers against D614G were observed in individuals who only received four-dose vaccination and those who experienced BA.5 BTI, which was also significantly higher than the antibody titers against XBB.1.5, EG.5.1, and BA.2.86. In contrast, only BA.5 infection elicited comparable neutralizing antibody titers against the tested variants. While neutralizing antibody titers against D614G or BA.5 were similar across the cohorts, the neutralizing capacity of antibodies against XBB.1.5, EG.5.1, and BA.2.86 was significantly reduced. BA.5 BTI following heterologous booster induced significantly higher neutralizing antibody titers against the variants, particularly against XBB.1.5 and EG.5.1, than uninfected vaccinated individuals, only BA.5 infected individuals, or those with BA.5 BTI after primary vaccination. Conclusions: Our findings suggest that repeated vaccination with the Wuhan-hu-1 strain imprinted a neutralizing antibody response toward the Wuhan-hu-1 strain with limited effects on the antibody response to the Omicron subvariants.

Abstract The development of advanced anode materials for lithium‐ion batteries that can provide high specific capacity and stable cycle performance is of paramount importance. This study presents a novel approach for synthesizing molecular‐level homogeneous carbon integration to porous SiO2 nanoparticles (SiO2@C NPs) tailored to enhance their electrochemical activities for lithium‐ion battery anode. By varying the ratio of the precursors for sol–gel reaction of (phenyltrimethoxysilane (PTMS) and tetraethoxysilane (TEOS)), the carbon content and porosity within SiO2@C NPs is precisely controlled. With a 4:6 PTMS and TEOS ratio, the SiO2@C NPs exhibit a highly mesoporous structure with thin carbon and the partially reduced SiOx phases, which balances ion and charge transfer for electrochemical activation of SiO2@C NPs resulting remarkable capacity and cycle performance. This study offers a novel strategy for preparing affordable high capacity SiO2‐based advanced anode materials with enhanced electrochemical performances.

Abstract The hydrological regime is considered to be the major factor that affects the distribution of arbuscular mycorrhiza (AM) fungi in wetlands. We aimed to investigate the responses of AM fungal community to different hydrological gradients. Illumina Miseq sequencing technology was used to study the AM fungal community structure in roots and rhizosphere soils of Phragmites australis in different moisture areas (dry area, alternating wet and dry area, and flooded area) in Mengjin Yellow River wetland. The rhizosphere soils and roots hosted different AM fungal communities. In roots, the AM fungal colonization and Chao1 richness in dry area were significantly higher than that in alternating wet and dry area and flooded area, but the community composition did not vary clearly under different water conditions. In rhizosphere soils, the Chao1 richness of AM fungi in flooded area was significantly higher than that in alternating wet and dry area and dry area, and the AM fungal community structure obviously differed across different areas. The redundancy analyses indicated that changes in the AM fungal community in soils were associated with altered soil properties, and the abundance of the dominant genus Glomus was mostly positively correlated with alkali‐hydrolyzable nitrogen in soils. This study helps us to understand the responses of AM fungal community to hydrological gradients in wetlands.

BackgroundFor cesarean delivery (CD), the 90% effective dosage (ED90) of oxytocin for a first bolus has been established. It is not yet known how much oxytocin to inject into obese women undergoing elective discectomy to keep their uterine tone (UT) appropriate. We hypothesized that patients who are overweight need a greater dose of oxytocin infusion; thus, we aimed to determine how the dose-response curve for oxytocin infusion changes following an initial 1 international unit (IU) bolus in obese women undergoing elective CD.MethodsOne hundred parturients with a body mass index (BMI) greater than 30 kg/m2 were randomly assigned to receive an infusion rate of 14, 18, 22, or 26 IU/h of oxytocin. When the uterine palpation is as hard as touching the forehead or tip of the nose, it is considered sufficient UT according to the criteria used by obstetricians. The median effective dose (ED50) and ED90 values were determined using probit analysis.ResultsWe found the ED50 and ED90 values for the infusion dose of oxytocin were around 11.0 IU/h and 19.1 IU/h, respectively. Each group had a different number of parturients who needed rescued oxytocin: 14 IU/h for six, 18 IU/h for three, one for 22 IU/h, and none for 26 IU/h. The correlation between the frequency of rescued oxytocin administration and the amount of oxytocin infusion needed to avoid uterine atony was statistically significant (p = 0.02).ConclusionThe present research showed that the most effective dosage of oxytocin infusion for obese parturients undergoing elective CD is 19.1 IU/h, following an initial loading dose of 1 IU. Patients with obesity should receive a greater dosage of prophylactic oxytocin, and further studies comparing patients with and without obesity (with higher BMI) are required.Clinical Trial Registrationhttps://www.chictr.org.cn/showproj.html?proj=159951, identifier ChiCTR2200059582.

Comparison of the epidemiological characteristics of the 2 groups, the proportions of corona virus disease (COVID⁃19) infection (χ2 = 4.217, P = 0.040) and psychopsychological symptoms (χ2 = 18.694, P = 0.000) in the FMD group were higher than those in the organic movement disorder group, while age (t = 3.757, P = 0.000), age of onset (t = 3.720, P = 0.000) and proportion of hypertension (χ2 = 4.736, P = 0.030) were lower than those in the organic movement disorder group. Comparison of the clinical characteristics of the 2 groups, the FMD group had higher proportions of tremor (χ2 = 3.955, P = 0.047) and myoclonus (Fisher′s exact probability: P = 0.011) than the organic movement disorder group, and the proportions of parkinsonism (χ2 = 8.491, P = 0.004) and gait disorder (χ2 = 5.028, P = 0.025) were lower than those in the organic movement disorder group. Conclusions The age and age of onset, as well as the proportions of COVID⁃19 infection, hypertension, psychopsychological symptoms, tremor, myoclonus, parkinsonism and gait disorder with FMD were different from those with organic movement disorder in China.

Impacts of economy-society-environment on surface water resource in China are complex and unclear. Revealing these connections is vital to understand responses of surface water quality to anthropogenic activities. This study made an attempt to explore potential indications on surface water quality from economic, social and environmental factors in eight separate regions of China during the period of 2000–2019. Five machine learning models were employed including Greedy Thick Thinning Bayesian Belief Network, Naive Bayes, Augmented Naive Bayes (ANB), Logistic Regression and Random Forest. A total of 8 economic variables, 5 social variables and 8 environmental variables were introduced into the models. Results showed that ANB presented the best performance in estimating the surface water quality class with the highest accuracies of 81%, 75% and 87% for three surface water quality groups (Class I–III, Class IV–V and worse than Class V), respectively. The higher the surface water environmental carrying capacity in a region, the better the estimation performance of ANB on the surface water quality class. Surface water quality with Class I–III was more closely related to economic and social development, while environmental variables largely interpreted the quality of surface water with Class IV–V in most regions. The critical factors filtered by the importance analysis were indicative on surface water quality. This study provided a feasible framework in revealing the economy-society-environment nexus in the context of comprehensive management on regional surface water quality.

To obtain healthy, low-sodium cured pork with good flavor, the processing optimization of the liquid smoke and baking was carried out through single factor experiment and orthogonal experiment in the present study. The effect of different amounts of smoking liquid, liquid smoking time, baking time and baking temperature on the yield, water activity, pH and color of low-sodium cured pork was investigated. Results showed that, the order affecting sensory quality of low-sodium cured pork was as follows: Baking temperature>baking time>smoking liquid amount>liquid smoking time. The optimized technological conditions of smoking and baking were as follows: The amount of smoking liquid was 4%, the time of liquid smoking was 150 min, the baking time was 28 h, the baking temperature was 50 ℃, and the sensory score of low-sodium cured pork under this processing technology was 37 points. The electronic tongue test was conducted to compare the taste of low-sodium cured pork with that of commercial cured pork. Results showed that the saltiness of low-sodium cured pork was significantly lower than that of commercial cured pork, and the bitterness and astringency were not significantly different from those of commercial cured pork.
