Evaluating Cell Death Signaling by Immunofluorescence in a Rat Model of Ischemic Stroke.

Stroke is a leading cause of death and disability worldwide. Most cases of stroke are ischemic and result from the occlusion of the middle cerebral artery (MCA). Current pharmacological approaches for the treatment of ischemic stroke are limited; therefore, novel therapies providing effective neuroprotection against ischemic injury following stroke are urgently needed.

RSL3 induces ferroptosis by activating the NF-κB signalling pathway to enhance the chemosensitivity of triple-negative breast cancer cells to paclitaxel.

Chemotherapy resistance in triple-negative breast cancer (TNBC) leads to poor therapeutic effects and a poor prognosis. Given that paclitaxel-based chemotherapy is the main treatment method for TNBC, enhancing its chemosensitivity has been a research focus. Induced ferroptosis of tumour cells has been proven to increase chemosensitivity, but its ability to sensitize TNBC cells to paclitaxel (PTX) is unknown.

Renovascular hypertension following by juxtaglomerular cell tumor: a challenging case with 12-year history of resistant hypertension and hypokalemia.

Background: Adolescents with secondary hyperaldosteronism often present with severe and treatment-resistant hypertension, along with hypokalemia. Renovascular hypertension is frequently caused by renal artery stenosis, primarily due to atherosclerosis and fibromuscular dysplasia (FMD). The presence of an accessory renal artery (ARA) is a common anatomical variation that can contribute to secondary renal vascular hypertension.

A comprehensive framework for trans-ancestry pathway analysis using GWAS summary data from diverse populations.

As more multi-ancestry GWAS summary data become available, we have developed a comprehensive trans-ancestry pathway analysis framework that effectively utilizes this diverse genetic information. Within this framework, we evaluated various strategies for integrating genetic data at different levels-SNP, gene, and pathway-from multiple ancestry groups. Through extensive simulation studies, we have identified robust strategies that demonstrate superior performance across diverse scenarios.

SurvBal: compositional microbiome balances for survival outcomes.

Summary: Identification of balances of bacterial taxa in relation to continuous and dichotomous outcomes is an increasingly frequent analytic objective in microbiome profiling experiments. SurvBal enables the selection of balances in relation to censored survival or time-to-event outcomes which are of considerable interest in many biomedical studies. The most commonly used survival models-the Cox proportional hazards and parametric survival models are included in the package, which are used in combination with step-wise selection procedures to identify the optimal associated balance of microbiome, i.

Dietary curcumin supplementation enhances growth performance and anti-inflammatory functions by modulating gut microbiota, microbiota-derived metabolites, and expression of inflammation-related genes in broilers.

Curcumin (CUR) is a natural polyphenolic substance that has been widely used since ancient times for its multiple beneficial functions. However, whether CUR affects the growth performance of broilers by altering gut microbiota and metabolite and the underlying mechanism are largely unknown. This study was conducted to evaluate the effect of dietary CUR supplementation on growth performance, anti-inflammatory function, intestinal morphology and barrier, cecum microbiota, and metabolite profile of broilers.

Introduction: Squamous cell cancer (SqCC) is a lung cancer subtype with few targeted therapy options. Molecular characterization, that is, by next-generation sequencing (NGS), is needed to identify potential targets. Lung Cancer Master Protocol Southwest Oncology Group S1400 enrolled patients with previously treated stage IV or recurrent SqCC to assess NGS biomarkers for therapeutic sub-studies.

Dietary curcumin supplementation attenuates hepatic damage and function abnormality in a chronic corticosterone-induced stress model in broilers.

Chronic stress refers to the activation of the hypothalamic-pituitary-adrenal (HPA) axis and elevated blood contents of ACTH and corticosterone (CORT), exhibiting significant adverse effects on health outcomes. Currently, natural polyphenol compounds are increasingly being explored as potential therapeutic agents and have been considered as a treatment option for a variety of stress-induced diseases. Curcumin (CUR) is the main substance in Curcuma longa (Zingiberacea) rhizome that has strong health-beneficial properties.

A multi-bin rarefying method for evaluating alpha diversities in TCR sequencing data.

Motivation: T cell receptors (TCRs) constitute a major component of our adaptive immune system, governing the recognition and response to internal and external antigens. Studying the TCR diversity via sequencing technology is critical for a deeper understanding of immune dynamics. However, library sizes differ substantially across samples, hindering the accurate estimation/comparisons of alpha diversities.

Pharmacological inhibition of RUNX1 reduces infarct size after acute myocardial infarction in rats and underlying mechanism revealed by proteomics implicates repressed cathepsin levels.

Myocardial infarction (MI) results in prolonged ischemia and the subsequent cell death leads to heart failure which is linked to increased deaths or hospitalizations. New therapeutic targets are urgently needed to prevent cell death and reduce infarct size among patients with MI. Runt-related transcription factor-1 (RUNX1) is a master-regulator transcription factor intensively studied in the hematopoietic field.
