Systematic transcriptome-wide analysis and validation of tributyltin-induced differential changes in the liver with sex-specific effects.

Background: Tributyltin (TBT), a prevalent environmental antiseptic, contaminates seafood, fish, and drinking water, posing health risks. While TBT's hepatic toxicity is well-known, its sex-specific effects on liver function remain poorly understood.

Methods: To address this gap, a comprehensive analysis was conducted utilizing the Toxicant Exposures and Responses by Genomic and Epigenomic Regulators of Transcription (TaRGET) dataset.

Multifunctional Near-Infrared Phosphors Cr/Ni Codoped MgGaGeO Based on Energy Transfer from Cr to Ni.

Currently, near-infrared (NIR) light-emitting materials have been widely used in many fields, such as night vision, bioimaging, and nondestructive analysis. However, it is difficult to achieve multifunction in certain NIR light emitting phosphor. Herein, we propose a new near-infrared phosphor MgGaGeO:Cr,Ni that can be applied to at least three fields, i.

Triptolide induces apoptosis and cytoprotective autophagy by ROS accumulation via directly targeting peroxiredoxin 2 in gastric cancer cells.

Triptolide, a natural bioactive compound derived from herbal medicine Tripterygium wilfordii, has multiple biological activities including anti-cancer effect, which is being tested in clinical trials for treating cancers. However, the exact mechanism by which Triptolide exerts its cytotoxic effects, particularly its specific protein targets, remains unclear. Here, we show that Triptolide effectively induces cytotoxicity in gastric cancer cells by increasing reactive oxygen species (ROS) levels.

Cornus officinalis vinegar reduces body weight and attenuates hepatic steatosis in mouse model of nonalcoholic fatty liver disease.

This study aimed to determine the main bioactive components of Cornus officinalis vinegar (COV) and assess the effects of COV on the body weight (BW) and hepatic steatosis in a nonalcoholic fatty liver disease (NAFLD) mouse model. Seven-week-old KM female mice were divided into five treatment groups: (1) Normal control (NC) group, (2) high fat diet (HFD) group, (3) low concentration treatment group (3.5% COV), (4) medium concentration treatment group (5.

Pre-miRNA Hsa-Let-7a-2: a Novel Intracellular Partner of Angiotensin II Type 2 Receptor Negatively Regulating its Signals.

G protein-coupled receptors (GPCRs) are the largest family of druggable targets, and their biological functions depend on different ligands and intracellular interactomes. Some microRNAs (miRNAs) bind as ligands to RNA-sensitive toll-like receptor 7 to regulate the inflammatory response, thereby contributing to the pathogenesis of cancer or neurodegeneration. It is unknown whether miRNAs bind to angiotensin II (Ang II) type 2 receptor (AGTR2), a critical protective GPCR in cardiovascular diseases, as ligands or intracellular interactomes.

Norswertianolin Promotes Cystathionine γ-Lyase Activity and Attenuates Renal Ischemia/Reperfusion Injury and Hypertension.

Cystathionine gamma-lyase (CSE)/hydrogen sulfide (HS) plays a protective role in cardiovascular diseases including hypertension and ischemia/reperfusion (I/R) injury. This study was aimed to screen natural small molecule compounds that activate CSE activity and then evaluate its effect(s) on kidney I/R injury and hypertension. Applying computer molecular docking technology, we screened the natural small molecule compound norswertianolin (NW)-specific binding to CSE.

[Safety analysis of application of medical anti-adhesion modified chitosan in cardiac surgery].

Objective: To verify the application safety of medical anti-adhesion modified chitosan (Baifeimi) in cardiac surgery.

Methods: From August to December 2010, 42 patients undergoing surgery for congenital heart disease, valvular heart disease or ischemic heart disease were selected and divided into testing (n = 22) and control (n = 20) groups. After complete intraoperative hemostasis, two sheets of anti-adhesion modified chitosan (Baifeimi) were placed on the surface of heart and vessels in the testing group and then chest was closed.
