A Au-catalyzed tandem alkyne hydroamination/iminium ion formation/allylation reaction was developed for expedient access to pyrrolidine derivatives bearing a tetrasubstituted carbon stereocenter. The tandem reaction was successfully applied to a 12-step asymmetric synthesis of (-)-lepadiformine A, a marine cytotoxic tricyclic alkaloid.

Cystic fibrosis (CF) is an autosomal recessive disorder caused by mutations in the gene. Currently, CFTR modulators are the most effective treatment for CF; however, they may not be suitable for all patients. A representative and convenient model is needed to screen therapeutic agents under development.

Introduction: Mitochondrial dysfunction stands as a pivotal feature in neurodegenerative disorders, spurring the quest for targeted therapeutic interventions. This review examines Ubiquitin-Specific Protease 30 (USP30) as a master regulator of mitophagy with therapeutic promise in Alzheimer's disease (AD) and Parkinson's disease (PD). USP30's orchestration of mitophagy pathways, encompassing PINK1-dependent and PINK1-independent mechanisms, forms the crux of this exploration.

Ventriculoperitoneal (VP) shunting is frequently associated with complications of which shunt-related infections are the most common. However, controversies still exist regarding the underlying factors. This study comparing peri-operative skin preparation agents was aimed at determining which factors among previously documented determinants of shunt infection are implicated in our practice setting.

Purpose: To evaluate whether the effectiveness of topical antiseptic solutions in restoring skin continuity solutions is related to their antimicrobial action or to their action in maintaining moisture, in dogs undergoing elective surgeries.
Methods: Forty dogs, 20 males and 20 females, underwent orchiectomy and oophorectomy, respectively. Thereafter, the animals were allocated into four groups (n = 5) and treated with different topical solutions: polyhexanide 0.
