Objectives: Microorganisms contribute to the pathogenesis of obesity, while more studies focus on gut microbiome. However, the relationship between oral microbiota and obesity has yet to be elucidated. This study was designed to investigate the similarities and differences in the effects of a high-fat diet on salivary and gut microbiota through mouse experiments, exploring the hypothesis that oral microbial mechanisms may contribute to obesity.

In this study, we investigated whether S100A7 can be used to predict the efficacy of neoadjuvant chemotherapy (NAC) and assessed its relationship with clinicopathological characteristics in BC.
Methods: We retrospectively analyzed the clinicopathological data of patients with BC who underwent NAC at the Fourth Hospital of Hebei Medical University between January 2021 and December 2021.
Botulinum neurotoxin (BoNT) is a highly lethal toxin produced by the anaerobic bacterium Clostridium botulinum, which leads to nerve paralysis following poisoning. At present, there is no specific drug officially approved. Antibodies, particularly single-domain antibodies, represent safe and effective candidates for specific drugs against BoNT.
View Article and Find Full Text PDFOxidative stress-induced cardiomyocyte apoptosis was the primary causative factor of cardiovascular disease (CVD). However, the existing therapy drugs for oxidative stress were much less investigated, which underlined the necessity for new drug discovery and development. Herein, we aimed to synthesize several novel idebenone (IDE) derivatives and investigate the protective effect and mechanism of these derivatives against HO-induced oxidative stress injury in H9C2 cells by determining cell proliferation rate, detecting the reactive oxygen species (ROS) level, and the expression of related proteins.

Methods: In this study, based on a field investigation of 9 lakes with varying water depths and nutrient levels in the Yunnan Plateau, southwest of China, we integrated water depth to predict the nutrient threshold of collapse and recovery of submerged macrophytes in lakes.
Background: Adequate bowel preparation is crucial for effective colonoscopy, especially in elderly patients who face a high risk of inadequate preparation. This study develops and validates a machine learning model to predict bowel preparation adequacy in elderly patients before colonoscopy.
Methods: The study adhered to the TRIPOD AI guidelines.
Allosteric modulation of protein function, which involves effector binding triggering distant conformational changes, is crucial for cellular and metabolic control. However, achieving tunable control, structural diversity, and precise intracellular regulation remains challenging. Here, we designed dynamic supramolecular protein assemblies driven by enzyme-substrate interactions for antioxidant regulation in cells.

Multiple pathogens, both tick-borne and enteric, can be involved as etiologic agents. An additional potential mechanism is intestinal barrier dysfunction.

Background: Sepsis is a critical condition associated with high morbidity and mortality, emphasizing the need for reliable biomarkers for its diagnosis and prognosis. This study uses advanced immunological techniques to evaluate monocytic CD39 (mCD39) expression as a potential marker in sepsis.
Methods: This prospective observational cohort study included 206 participants from the First Affiliated Hospital, Zhejiang University School of Medicine between April 2022 and September 2023.
Objective: L5/S1 segment is one of the most common lumbar degenerative segments with high clinical failure rate. When the clinically responsible segment consists of one or more segments including L4/L5 segment, whether to merge the severely degraded L5/S1 segment together is a common problem plaguing clinicians. Therefore, the purpose of this study was to explore the risk factors for preoperative adjacent segment degeneration L5/S1 segment occuring Postoperative adjacent segment disease(ASDis), analyze the correlation between the high risk factors and the occurrence of adjacent segment disease, clarify the preventive measures and direction, and provide references for clinical selection of personalized treatment.

Although several azobenzene-based photoresponsive ILs have been synthesized, there is still a lack of understanding regarding the aggregation mechanism, regularity of the alkyl chain length, and the position of the azobenzene (cis- and trans-) in these photoresponsive ILs. To elucidate the structure-property relationship of photoresponsive ILs, four types of azobenzene groups photosensitive ILs ([AzoCDMEA]Br, n = 2,4,6,10) in both trans- and cis- configurations were investigated by density functional theory (DFT) calculations.

Methods: A retrospective analysis was conducted on 499 patients who underwent radical gastrectomy under general anesthesia at our center between January 2023 and January 2024. After 1:1 propensity score matching, the experimental group comprised 157 patients whose operation cavities were examined after increasing blood pressure before the end of gastrectomy, while the control group included 157 patients whose operation cavities were examined using routine procedures without increasing blood pressure.
Objectives: This systematic review and meta-analysis aimed to investigate the association between vaccinations and the risk of rheumatoid arthritis (RA), specifically addressing concerns about a potential increased risk among vaccinated individuals.
Methods: A systematic search for cohort studies and case-control studies examining the association between vaccinations and RA was conducted using Medical Subject Headings and relevant keywords across PubMed, EMBASE, and Cochrane Library databases from inception to September 2024. The risk of bias of included studies was assessed using the Newcastle-Ottawa Scale.
Mitochondria dysfunction has been closely linked to a wide spectrum of human cancers, whereas the molecular basis has yet to be fully understood. SLC25A35 belongs to the SLC25 family of mitochondrial carrier proteins. However, the role of SLC25A35 in mitochondrial metabolism reprogramming, development and progression in human cancers remains unclear.

As the Chinese government fully implements the tiered diagnosis and treatment system, community health service centers will take on an increased role in the diagnosis and treatment of mental disorders. However, Chinese general practitioners currently have limited expertise in mental health.
View Article and Find Full Text PDFTumor-associated macrophages (TAMs) are crucial in hepatocellular carcinoma (HCC) development and invasion. This study explores monocyte/ macrophage-associated gene expression profiles in HCC, constructs a prognostic model based on these genes, and examines its relationship with drug resistance and immune therapy responses. Single-cell RNA sequencing(scRNA-seq) data from 10 HCC tissue biopsy samples, totaling 24,597 cells, were obtained from the GEO database to identify monocyte/macrophage-associated genes.

Methods: With a nested case-control design, a risk-set sampling method was used to match cases and controls.
As society ages, improving the health of the elderly through effective training programs has become a pressing issue. Virtual reality (VR) technology, with its immersive experience, is increasingly being utilized as a vital tool in rehabilitation training for the elderly. To further enhance training outcomes and improve health conditions among the elderly, this work proposes an integrated model that combines the Generative Adversarial Network (GAN), Variational Autoencoder (VAE), and Long Short-Term Memory (LSTM) network.

Method: Data were extracted from the Electronic Medical Record System of Zhoushan, China. Adverse outcomes include small for gestational age (SGA), large for gestational age (LGA), low birth weight and macrosomia.
Reprogramming T cell metabolism can improve intratumoural fitness. By performing a CRISPR/Cas9 metabolic survey in CD8 T cells, we identified 83 targets and we applied single-cell RNA sequencing to disclose transcriptome changes associated with each metabolic perturbation in the context of pancreatic cancer. This revealed elongation of very long-chain fatty acids protein 1 (Elovl1) as a metabolic target to sustain effector functions and memory phenotypes in CD8 T cells.
