Nitrosyl factors play a vital role in the ventilatory depressant effects of fentanyl in freely moving guinea pigs.

An understanding of intracellular mechanisms by which fentanyl and other synthetic opioids exert adverse effects on breathing is needed. Using freely moving adult male guinea pigs, we administered the nitric oxide synthase (NOS) inhibitor, L-NAME (N-nitro-L-arginine methyl ester), to determine whether nitrosyl factors, such as nitric oxide and S-nitrosothiols, play a role in fentanyl-induced respiratory depression. Ventilatory parameters were recorded by whole body plethysmography to determine the effects of fentanyl (75 μg/kg, IV) in guinea pigs that had received a prior injection of vehicle (saline), L-NAME or the inactive D-isomer, D-NAME (both at 50 μmol/kg, IV), 15 min beforehand.

This review seeks to provide a comprehensive synthesis of current knowledge on diagnosing and managing BA-associated cholangitis while identifying gaps in the existing literature. A scoping literature review was conducted to gather global insights into the definition, evaluation, and management of post-Kasai cholangitis, illustrated through data from the Swiss Biliary Atresia Registry (SBAR).

Genetics of biliary atresia: Approaches, pathological insights and challenges.

Biliary atresia (BA) is a severe neonatal cholestatic disorder marked by fibro-obliteration of the extrahepatic and intrahepatic bile ducts. It is the most common cause of pediatric end-stage liver disease and the leading indication for liver transplantation in children. There is significant heterogeneity in the etiology, involving various genetic and environmental factors such as viral infection, immune dysregulation and genetic predisposition to defective hepatobiliary development.

Immunology of Biliary Atresia.

Biliary atresia is a progressive neonatal cholangiopathy that leads to liver failure. Characterized by inflammation-mediated liver injury, the immune system plays a critical role in the pathogenesis of this disease. Though several types of immune cells and mediators have been implicated in animal models of biliary atresia, emerging literature reflects the complex interplay of components of the immune response that contributes to disease progression in humans.
