Objectives: To investigate the efficacy of prophylactic embolization of the internal iliac artery (IIA) or superior gluteal artery (SGA) before open reduction and internal fixation (ORIF) in reducing intraoperative blood loss (IBL) in hemodynamically stable patients with complex acetabular fractures.

Materials And Methods: A total of 136 patients with complex acetabular fractures were retrospectively included and divided into the prophylactic transcatheter arterial embolization (PTAE) group and non-PTAE group, depending on whether ipsilateral IIA or SGA was embolized using coils within 3 days before ORIF. Demographic characteristics, injury severity score (ISS), fracture classification, and intraoperative and postoperative data were compared between the two groups.

Aflatoxin B1 (AFB1) is a prevalent contaminant in food and feed matrices, known for its hepatotoxic effects. Its metabolic breakdown generates reactive oxygen species (ROS), leading to oxidative stress and subsequent liver damage. Mitigating oxidative stress is, therefore, essential for ameliorating the hepatocellular damage and systemic toxicity caused by AFB1.

The 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model remains the most extensively utilized animal model for Parkinson's disease (PD). Treatment regimens are classified into three categories: acute, subacute, and chronic. Among these, the MPTP with probenecid (MPTP/p)-induced chronic mouse model is favored for its capacity to sustain long-term striatal dopamine depletion, though the resultant behavioral, biochemical, and molecular alterations require further validation.

Parkinson's disease is the second most common neurodegenerative disease, characterized by substantial loss of dopaminergic (DA) neurons, the formation of Lewy bodies (LBs) in the substantia nigra, and pronounced neuroinflammation. The nucleotide-binding domain like leucine-rich repeat- and pyrin domain-containing protein 3 (NLRP3) inflammasome is one of the pattern recognition receptors (PRRs) that function as intracellular sensors in response to both pathogenic microbes and sterile triggers associated with Parkinson's disease. These triggers include reactive oxygen species (ROS), misfolding protein aggregation, and potassium ion (K) efflux.

Androgens, such as 5α-dihydrotestosterone (5α-DHT), regulate numerous functions by binding to nuclear androgen receptors (ARs) and potential unknown membrane receptors. Here, we report that the androgen 5α-DHT activates membrane receptor GPR133 in muscle cells, thereby increasing intracellular cyclic AMP (cAMP) levels and enhancing muscle strength. Further cryoelectron microscopy (cryo-EM) structural analysis of GPR133-Gs in complex with 5α-DHT or its derivative methenolone (MET) reveals the structural basis for androgen recognition.
