The application of these therapies is highly dependent on the evaluation of tumor HER2 status. However, there are many risks and challenges in HER2 assessment in GC.

Aging-induced Alternation in the Gut Microbiota Impairs Host Antibacterial Defense.

Older individuals experience increased susceptibility and mortality to bacterial infections, but the underlying etiology remains unclear. Herein, it is shown that aging-associated reduction of commensal Parabacteroides goldsteinii (P. goldsteinii) in both aged mice and humans critically contributes to worse outcomes of bacterial infection.

A novel necroptosis-related gene signature predicts the prognosis and immunotherapeutic response in breast cancer through immune infiltration.

Growing evidence has demonstrated the association between necroptosis and tumorigenesis and immunotherapy. However, the influence of overall necroptosis related genes on prognosis and immune microenvironment of breast cancer is still unclear. In this study, We systematically analyzed the necroptosis related gene patterns and tumor microenvironment characteristics of 1294 breast cancer patients by clustering the gene expression of 22 necroptosis related genes.

Anti-neuroinflammatory and Neuroprotective Effects of T-006 on Alzheimer's Disease Models by Modulating TLR4-Mediated MyD88/ NF-κB Signaling.

Introduction: Neuroinflammation derived from the activation of the microglia is considered a vital pathogenic factor of Alzheimer's Disease (AD). T-006, a tetramethylpyrazine derivative, has been found to alleviate cognitive deficits via inhibiting tau expression and phosphorylation in AD transgenic mouse models. Recently, T-006 has been proven to dramatically decrease the levels of total Amyloid β (Aβ) peptide and Glial Fibrillary Acidic Protein (GFAP) and suppress the expression of ionized calcium binding adaptor molecule-1 (Iba-1) in APP/PS1 mice.

Highly Selective AIEgen-Based "Turn On" Fluorescent Imaging for Inflammation Detection.

Hypochlorous acid (HClO) is released by immune cells in the immune system, and it helps the body fight off infections and inflammation by killing bacteria, viruses, and other pathogens. However, tissue damage or apoptosis may also be induced by excess HClO. On this basis, we designed the probe TPE-NS by choosing tetraphenylethylene (TPE) as the luminescent unit and dimethylthiocarbamoyl chloride as the recognition site.

One-Shot Synthesis of Sym- and Asym-Expanded Heterohelicene Isomers Exhibiting Narrowband Deep-Blue Fluorescence.

Expanded heterohelicene composing of alternating linearly and angularly fused multi-resonance (MR) skeleton has garnered wide interest for their promising narrowband emission. Herein, a pair of sym- and asym-expanded heterohelicene isomers are firstly developed by merging boron/oxygen (B/O)-embedded MR triangulene and indolo[3,2,1-jk]carbazole units via one-shot synthesis. Owing to the fully resonating extended helical skeleton, the target heterohelicenes exhibit significantly narrowed spectra bandwidth while emission red-shifting, thus affording deep-blue narrowband emission with peak at around 460 nm, full-width-at-half-maximum (FWHM) of merely 18 nm and near-unity photoluminescence quantum yields.

Intermittent Fasting Enhances Motor Coordination Through Myelin Preservation in Aged Mice.

Integrating dietary interventions have been extensively studied for their health benefits, such as Alzheimer's disease, Huntington's disease, and aging. However, it is necessary to fully understand the mechanisms of long-term effects and practical applications of these dietary interventions for health. A 10-week intermittent fasting (IMF) regimen was implemented on the aging animals in the current study.

The association between estimated pulse wave velocity and cardio-cerebrovascular disease risk: a cohort study.

Background: Various measures of arterial stiffness have been linked to the risk of cardiovascular disease.

The patients in this study were enrolled from the Investigation on Nutrition Status and Clinical Outcome of Common Cancers (INSCOC) project.

Arsenic accumulation and reproductive toxicity in freshwater snail (Pomacea canaliculata).

This study aimed to investigate the tissue-specific accumulation patterns of arsenic (As) and the potential toxicological effects of As on the oviposition of a globally distributed aquatic invertebrate, the apple snail (Pomacea canaliculata). An eight-compartment physiologically based pharmacokinetic (PBPK) model was utilized to simulate the distribution and depuration kinetics of arsenite and arsenate in the snails. Modeling and biotransformation suggested that intestine-stomach was the main uptake site for As and plays an important role in maintaining the balance of As species.

SEE: A Method for Predicting the Dynamics of Chromatin Conformation Based on Single-Cell Gene Expression.

The dynamics of chromatin conformation involve continuous and reversible changes within the nucleus of a cell, which participate in regulating processes such as gene expression, DNA replication, and damage repair. Here, SEE is introduced, an artificial intelligence (AI) method that utilizes autoencoder and transformer techniques to analyze chromatin dynamics using single-cell RNA sequencing data and a limited number of single-cell Hi-C maps. SEE is employed to investigate chromatin dynamics across different scales, enabling the detection of (i) rearrangements in topologically associating domains (TADs), and (ii) oscillations in chromatin interactions at gene loci.

Increased Mineral-Associated Organic Carbon and Persistent Molecules in Allochthonous Blue Carbon Ecosystems.

Coastal wetlands contain very large carbon (C) stocks-termed as blue C-and their management has emerged as a promising nature-based solution for climate adaptation and mitigation. The interactions among sources, pools, and molecular compositions of soil organic C (SOC) within blue C ecosystems (BCEs) remain elusive. Here, we explore these interactions along an 18,000 km long coastal line of salt marshes, mangroves, and seagrasses in China.

The prognosis and immune repertoire characteristics of HBsAg and anti-HBs double positive chronic hepatitis B patients.

Coexistence of hepatitis B surface antigen (HBsAg) and hepatitis B surface antibody (anti-HBs) has been observed in some chronic hepatitis B (CHB) patients (DP patients), but the clinical outcomes and comprehensive characterization of immune micro-environmental changes for this specific population remain inconclusive. In this study, we retrospectively analyze the prognosis of 305 patients in Foshan City, Guangdong Province, China, and also investigated the molecular immunology changes in HBsAg and anti-HBs double positive CHB patients (DP group), CHB patients who had recovered from IFN-ɑ treatment (RP group), and healthy controls (HC group) using T cell receptor (TCR) and B cell receptor (BCR) immune repertoire sequencing. Our findings revealed that 22.

A SYBR green I-based multiplex real-time PCR for simultaneous detection of pseudorabies virus, porcine circovirus 3 and porcine parvovirus.

Background: Pseudorabies virus (PRV), porcine parvovirus (PPV) and porcine circovirus 3 (PCV3) are common in swine farms in China. Single infection or co-infection with PRV, PPV and/or PCV3 was difficult to distinguish between their clinical symptoms and pathological changes. Therefore, a quick and accurate detection method is needed for epidemiological surveillance, disease management, import and export control.
