Timosaponin B II as a novel KEAP1-NRF2 inhibitor to alleviate alcoholic liver disease:Receptor structure-based virtual screening and biological evaluation.

Oxidative stress induced by excess ethanol is an important factor in the progression of alcoholic liver disease (ALD). In recent years, inhibiting Kelch-like ECH-associated protein 1 (KEAP1) to activate the antioxidant regulator Nuclear factor erythroid 2-related factor 2 (NRF2) has been considered an effective strategy for treating oxidative stress-related diseases, but its application in ALD remains insufficiently explored. This study aims to discover high-affinity inhibitors targeting the KEAP1 receptor.

Relationship Between Depression and Epigallocatechin Gallate from the Perspective of Gut Microbiota: A Systematic Review.

Depression, a serious mental illness, is characterized by high risk, high incidence, persistence, and tendency to relapse, posing a significant burden on global health. The connection between depression and gut microbiota is an emerging field of study in psychiatry and neuroscience. Understanding the gut-brain axis is pivotal for understanding the pathogenesis and treatment of depression.

Chronic restraint stress affects the diurnal rhythms of gut microbial composition and metabolism in a mouse model of depression.

Background: Depression is a common mental disorder accompanied by gut microbiota dysbiosis, which disturbs the metabolism of the host. While diurnal oscillation of the intestinal microbiota is involved in regulating host metabolism, the characteristics of the intestinal microbial circadian rhythm in depression remain unknown. Our aim was to investigate the microbial circadian oscillation signature and related metabolic pathways in a mouse model with depression-like behaviours.

CTCNet: a fine-grained classification network for fluorescence images of circulating tumor cells.

The identification and categorization of circulating tumor cells (CTCs) in peripheral blood are imperative for advancing cancer diagnostics and prognostics. The intricacy of various CTCs subtypes, coupled with the difficulty in developing exhaustive datasets, has impeded progress in this specialized domain. To date, no methods have been dedicated exclusively to overcoming the classification challenges of CTCs.

The T cell receptor (TCR) repertoire's role in SLE has garnered significant interest due to its potential in both diagnostics and therapeutics. Our study aimed to delineate the variances in the TCRβ repertoire between patients with SLE and healthy individuals, correlating these differences with the severity and subtypes of SLE.

Optimal doses of intranasal esketamine plus dexmedetomidine for sedating toddlers during transthoracic echocardiography: a prospective, double-blind, randomized trial.

Introduction: Esketamine has unique advantages in combination with dexmedetomidine for sedation in young children, owing to its sympathetic activity and mild respiratory depression. However, the optimal dose is yet to be determined. In this study, we compared the different doses of intranasal esketamine combined with dexmedetomidine for sedation during transthoracic echocardiography in toddlers.

Unraveling diabetic kidney disease: insights from single-cell RNA sequencing.

The incidence of diabetic kidney disease (DKD) is rising annually. Diabetes leads to structural damage and dysfunction in the kidneys, clinically manifesting as progressive proteinuria and declining renal function, ultimately resulting in end-stage renal disease (ESRD). Recent findings have identified a subset of DKD known as normoalbuminuric diabetic kidney disease (NADKD), characterized by normal urine albumin levels but reduced renal function.

Gaps in knowledge and management of iron deficiency in heart failure: a nationwide survey of cardiologists in China.

CCL3 as a novel biomarker in the diagnosis of necrotizing enterocolitis.

Objectives: Neonatal necrotizing enterocolitis (NEC) is a common intestinal disease that threatens the lives of newborns and is characterized by ischemic necrosis of the small intestine and colon. As early diagnosis of NEC improves prognosis, the identification of new or complementary biomarkers is of great importance. In this study, we evaluate the diagnostic value of CCL3 in NEC and compare its effectiveness with other commonly used biomarkers, such as procalcitonin (PCT) and C-reactive protein (CRP).

Development and psychometric testing of the psychological capital questionnaire for nurses.

Background: Psychological capital (PsyCap) is a positive internal resource for individuals, playing a crucial role in mental health. Evaluating nurses' psychological capital is important for understanding their mental well-being, as they face unique occupational stressors. However, existing PsyCap questionnaires are developed for various other professions such as enterprise employees, teachers, patients, teenagers, and civil servants, making them less suitable for the nursing profession.

Electrophotocatalytic Thiocyanation and Sulfonylation Cyclization of Unactivated Alkenes.

We report an electrophotocatalytic process that enables the thiocyanation and sulfonylation/cyclization of alkenes. It is applicable to a wide range of unactivated alkenes, using the inexpensive photocatalyst 2,4,6-triphenylpyrylium tetrafluoroborate (TPPT) to produce a diverse array of heterocycles containing sulfonyl and thiocyano groups with good functional group tolerance. The protocol operates under mild, chemical oxidant- and transition-metal-free, with a broad scope of substrates.
