The aim of this study was to investigate whether (E)-2-benzylidene-4-phenyl-1,3-diselenole (BPD) protects against hepatotoxicity induced by thioacetamide (TAA). On the first day of treatment, male adult Wistar rats received BPD (10 or 50 mg·kg). On the second day, the rats received a single intraperitoneal injection of TAA (400 mg·kg). Twenty-four hours after TAA administration, biochemical determinations and liver histological analysis were carried out. BPD (50 mg·kg) reduced plasma aspartate and alanine aminotransferase, alkaline phosphatase, and lactate dehydrogenase activities increased by TAA exposure. Treatment with BPD was effective against increased lipid peroxidation levels and attenuated a decrease in hepatic reduced glutathione and ascorbic acid levels as well as an inhibition of glutathione peroxidase activity caused by TAA exposure. The higher dose of BPD protected against the inhibition of hepatic δ-aminolevulinic dehydratase activity induced by TAA. Finally, histopathological examination of the liver showed that BPD markedly ameliorated TAA-induced hepatic injury. In conclusion, BPD protected against hepatotoxicity and oxidative stress caused by TAA exposure in rats.

Hepatic encephalopathy (HE) is a syndrome that arises from acute or chronic liver failure. This study was devised to assess the impact of a combination of boswellic acid (BA) and low doses of gamma radiation (LDR) on thioacetamide (TAA)-induced HE in an animal model. The effect of daily BA treatment (175 mg/kg body weight, for four weeks) and/or fractionated low-dose γ-radiation (LDR; 0.

Experimental animal models are crucial for elucidating the pathophysiology of liver injuries and for assessing new hepatoprotective agents. Drugs and chemicals such as acetaminophen, isoniazid, valproic acid, ethanol, carbon tetrachloride (CCl), dimethylnitrosamine (DMN), and thioacetamide (TAA) are metabolized by the CYP2E1 enzyme, producing hepatotoxic metabolites that lead to both acute and chronic liver injuries. In experimental settings, acetaminophen (centrilobular necrosis), carbamazepine (centrilobular necrosis and inflammation), sodium valproate (necrosis, hydropic degeneration and mild inflammation), methotrexate (sinusoidal congestion and inflammation), and TAA (centrilobular necrosis and inflammation) are commonly used to induce various types of acute liver injuries.

Background: Occupational exposure to high levels of noise increases the risk of noise-induced hearing loss (NIHL), resulting in significant long-term quality of life implications. Hearing protection is recommended if occupational noise exposure routinely exceeds 85 decibels (dB). The purpose of this study was to determine if foot and ankle surgeons are exposed to excessive levels of noise, thus putting them at an increased risk for NIHL.

The purpose of this study was to identify risk factors for being discharged to a non-home destination following total ankle arthroplasty (TAA). We included patients undergoing TAA from the American College of Surgeons National Surgical Quality Improvement Program database (NSQIP) between 2014 and 2019.
