The ultimate aim of this present study was to investigate the antihyperlipidemic and antiapoptotic potential of zingerone (ZO) on alcohol induced hepatotoxicity in experimental rats. Male albino wistar rats were divided in four groups. Groups 1 and 2 rats received isocaloric glucose and dimethyl sulphoxide (2% DMSO), liver toxicity was induced in groups 3 and 4 by supplementing 30% ethanol post orally for 60 days. In addition to, groups 2 and 4 received zingerone (20 mg/kg body weight in 2% DMSO) daily during the final 30 days of the experimental period. Ethanol alone administered rats showed increased levels/activities of plasma total cholesterol (TC), triglycerides (TG), free fatty acids (FFA), phospholipids (PL), low density lipoproteins (LDL), very low density lipoproteins (VLDL), tissue TC, TG, FFA, PL, HMG-CoA reductase, phase I xenobiotic enzymes, collagen and fat accumulation, DNA damage and increased Bax, caspase-3 and caspase-9 expressions and decrease in the levels/activities of plasma high density lipoproteins (HDL), lipoprotein lipase (LPL), lecithin cholesterol acyl transferase (LCAT), phase II xenobiotic enzymes and a decreased Bcl-2 expression. Zingerone supplementation was able to counter and reverse the ethanol induced changes in all the above parameters in experimental rats. Together results portray zingerone exhibits antihyperlipidemic and antiapoptotic potential on alcohol induced hepatotoxicity.

This study is aimed at investigating the effects of atorvastatin (ATV) on endothelial cell injury in atherosclerosis (AS) through inhibiting acyl-CoA synthetase long-chain family member 4 (ACSL4)-mediated ferroptosis. Human umbilical vein endothelial cells (HUVECs) were treated with oxidized low-density lipoprotein (ox-LDL) to establish an in vitro model of AS. The cell viability, lactate dehydrogenase (LDH) release, apoptosis, and expression levels of apoptotic proteins were assessed.

Article Synopsis
- The study investigates chitosan nanoparticles derived from Nyctanthes arbor-tristis leaves as a potential treatment for aggressive gynecological tumors, aiming to reduce the side effects of conventional therapies.
- The nanoparticles were thoroughly characterized and showed efficacy against breast and ovarian cancer cells, demonstrating dose-dependent cytotoxicity and the ability to induce apoptosis.
- In vivo tests on zebrafish indicated low toxicity for the nanoparticles, suggesting they could be a promising new option for cancer treatment in women.

Excessive fluoride exposure beyond the tolerable limit may adversely impacts brain functionality. Betaine (BET), a trimethyl glycine, possesses antioxidant, anti-inflammatory and anti-apoptotic functions, although the underlying mechanisms of the role of BET on fluoride-induced neurotoxicity remain unelucidated. To assess the mechanism involved in the neuro-restorative role of BET on behavioural, neurochemical, and histological changes, we employed a rat model of sodium fluoride (NaF) exposure.

Background: Tuberculosis (TB) is a leading cause of infection related mortality. Isoniazid is one of the frontline drugs for anti-TB therapy. Hepatotoxicity induced by isoniazid is a major cause of drug-discontinuation which may lead to development of resistant TB or increased mortality.

Hydrogel-derived implants have proven value in bone tissue regeneration, and current efforts have concentrated on devising strategies for producing functional implants with desired structures and functions to improve therapeutic outcomes. Herein, a novel black phosphorus (BP) tagged responsive strontium (Sr) hydrogel particles are presented for bone defect repair. By applying microfluidic technology, Sr and carboxymethyl chitosan, and BP are integrated into poly(N-isopropyl acrylamide) (pNIPAM) hydrogel matrix to generate such microparticles called pNBCSMs.
