Introduction: Coronaviruses and influenza viruses are significant respiratory pathogens that cause severe disease burdens and economic losses for society. Due to their diversity and evolution, vaccines typically require periodic updating to remain effective. An additional challenge is imposed by the possible coinfection of SARS-CoV-2 and influenza, which could increase disease severity.

Article Synopsis
  • The study addresses challenges in using small-diameter vascular grafts, such as thrombosis and inflammation, by creating a suitable microenvironment through advanced materials.
  • Researchers developed a hybrid material by blending poly(ester-urethane)urea (PEUU) with varying levels of resveratrol, tested these for properties like mechanical strength and biocompatibility, and discovered that resveratrol enhances the performance of the graft.
  • The findings demonstrate that the optimal formulation (P/R-1.0) effectively supports endothelial cell growth and neovascularization, making it a promising candidate for improving vascular graft performance.

Article Synopsis
  • Cervical cancer (CC) is a serious global health issue, especially challenging in advanced stages, with a need for better ways to predict patient outcomes and response to immunotherapy due to its complexity.
  • Researchers analyzed 92 proteins in the plasma of CC patients undergoing immunotherapy, finding 55 proteins that showed significant changes indicating response or progression of disease, and developed a predictive model based on five key proteins.
  • The study suggests that using multiple biomarkers can enhance prognosis predictions for CC patients and potentially guide personalized immunotherapy treatments, thus improving clinical strategies for those with poor prognoses.

Article Synopsis
  • CAR-T cells, specifically a new version called M10 cells, combine broadly neutralizing antibodies and the CXCR5 receptor to target HIV-1 effectively.
  • M10 cells were tested in 18 patients, with results showing that 74.3% of infusions led to a significant decrease in viral loads and persistent reductions in HIV-1 RNA levels.
  • The study suggests M10 CAR-T cells could be a promising and safe treatment option for achieving a functional cure for HIV-1/AIDS, with no major side effects reported.

Purpose: Olaparib, an inhibitor of poly-(adenosine diphosphate-ribose) polymerase (PARP), has been shown to have anticancer benefits in patients with pancreatic cancer who have a germline mutation in BRCA1/2. However, resistance acquired on long-term exposure to olaparib significantly impedes clinical efficacy.

Methods: In this study, the chromatin accessibility and differentially expressed transcripts of parental and olaparib-resistant pancreatic cancer cell lines were assessed using the Assay for Transposase Accessible Chromatin with sequencing (ATAC-seq) and mRNA-seq.

Pancreatic cancer (PCa) is one of the most fatal human malignancies. The enhanced infiltration of stromal tissue into the PCa tumor microenvironment limits the identification of key tumor-specific transcription factors and epigenomic abnormalities in malignant epithelial cells. Integrated transcriptome and epigenetic multiomics analyses of the paired PCa organoids indicate that the basic helix-loop-helix transcription factor 40 (BHLHE40) is significantly upregulated in tumor samples.

Background: LIPH, a membrane-associated phosphatidic acid-selective phospholipase A1a, can produce LPA (Lysophosphatidic acid) from PA (Phosphatidic acid) on the outer leaflet of the plasma membrane. It is well known that LIPH dysfunction contributes to lipid metabolism disorder. Previous study shows that LIPH was found to be a potential gene related to poor prognosis with pancreatic ductal adenocarcinoma (PDAC).

Neuropathy is a feature more frequently observed in pancreatic ductal adenocarcinoma (PDAC) than other tumors. Schwann cells, the most prevalent cell type in peripheral nerves, migrate toward tumor cells and associate with poor prognosis in PDAC. To unveil the effects of Schwann cells on the neuro-stroma niche, here we perform single-cell RNA-sequencing and microarray-based spatial transcriptome analysis of PDAC tissues.

: Accumulating evidence illustrated that the reprogramming of the super-enhancers (SEs) landscape could promote the acquisition of metastatic features in pancreatic cancer (PC). Given the anatomy-based TNM staging is limited by the heterogeneous clinical outcomes in treatment, it is of great clinical significance to tailor individual stratification and to develop alternative therapeutic strategies for metastatic PC patients based on SEs. : In our study, ChIP-Seq analysis for H3K27ac was performed in primary pancreatic tumors (PTs) and hepatic metastases (HMs).

Purpose: This study aimed to quantify the preferences of Chinese patients with schizophrenia and their caregivers for antipsychotic treatment.

Patients And Methods: Patients with schizophrenia (aged 18-35) and their caregivers were recruited via six outpatient mental health clinics in Shanghai, People's Republic of China. In a discrete choice experiment (DCE), participants chose between two hypothetical treatment scenarios that varied regarding the type of treatment, rate of hospitalization, severity of positive symptoms, treatment cost and rates of improvement in daily and social functioning.

Background: Checkpoint-based immunotherapy has failed to elicit responses in the majority of patients with pancreatic cancer. In our study, we aimed to identify the role of a novel immune checkpoint molecule V-set Ig domain-containing 4 (VSIG4) in pancreatic ductal adenocarcinoma (PDAC).

Methods: Online datasets and tissue microarray (TMA) were utilized to analyze the expression level of VSIG4 and its correlation with clinical parameters in PDAC.

Background: Both autophagy and glycolysis are essential for pancreatic ductal adenocarcinoma (PDAC) survival due to desmoplasia. We investigated whether targeting a hub gene which participates in both processes could be an efficient strategy for PDAC treatment.

Methods: The expression pattern of glycolysis signatures (GS) and autophagy signatures (AS) and their correlation with cystatin B (CSTB) in PDAC were analysed.

Introduction: Benzodiazepine receptor agonists (BZRAs), which include benzodiazepines and Z-drugs, are the most commonly prescribed psychotropic drugs worldwide, and their inappropriate use places a significant burden on public health. Given the widespread use of BZRAs in psychiatric settings, this condition may result from doctors' improper prescribing. Researchers have developed an electronic intervention system to assist psychiatrists in prescribing BZRAs appropriately.

Given the importance of the cerebellum in the pathophysiology of schizophrenia, the cerebellar vermis has been proposed as a new rTMS stimulation site for negative symptoms. In this study, 64 patients from 7 psychiatric hospitals were randomized into the study (n=32) or control (n=32) group. Intermittent theta burst stimulation (iTBS) (or sham stimulation) to the cerebellar midline was administered 5 times/week for 2 weeks.

The soil contaminated with heavy metals requires special attention due to its adverse effects on health of human and animals. The effects of simulated acid rain with different pH values on transport of heavy metal in contaminated soil of Phyllostachys pubescens forest were studied by indoor leaching column test. The results revealed that particle size of soil was mainly concentrated in range of more than 50 μm.

In this study, we investigated the role of tumor-associated macrophages (TAMs) in the progression of pancreatic ductal adenocarcinoma (PDAC). PDAC patients with higher levels of CD68 TAMs exhibited shorter overall survival. In Transwell assays, PDAC cells incubated with TAMs or conditioned media from TAM cells (TAM-CM) showed higher migration and invasion rates than controls.
