To investigate the mechanism of pancreatic alveolar cell autophagy in rats with severe acute pancreatitis (SAP) by phillygenin (PHI) based on the PI3K/Akt/mToR pathway. Rats were randomly divided into control group (CON group), SAP model group (SAP group) and PHI treatment group (SAP+PHI group), with 10 rats in each group. 5% sodium taurocholate was injected retrogradely into the biliopancreatic duct to establish a SAP rat model, and PHI was injected intraperitoneally into the pancreas after successful establishment of the model. The colorimetric assay was used to determine serum amylase and lipase activity levels. Pancreatic morphology and histological changes were assessed by H&E staining. Autophagy-related indices were determined by immunohistochemistry: LC3-II, P62, LAMP. Autophagy pathway-related indices were determined by western blotting assay: p-PI3K, PI3K, p-Akt, Akt, p-mToR, mToR. Autophagy vesicle alteration. Compared with the SAP group, the SAP+PHI group showed a decrease in amylase, lipase and pathological score, an increase in the expression of LAMP-2, and a decrease in the expression of p62, p-PI3K, p-Akt and p-mToR, with a statistically significant difference ( < 0.05). Electron microscopy showed that autophagic flux was restored and accumulated autophagic vehicles were relatively reduced by PHI intervention. PHI can rescue the impaired autophagic flux by inhibiting the PI3K/Akt/mToR pathway, allowing abnormal autophagic vesicles to complete autophagy to protect the rat.

Aims: To assess self-reported practices and knowledge of nurses and prescribers (i.e., physicians and nurse practitioners) on intravenous fluid therapy, and to evaluate how this is documented through a clinical documentation review.

Background: Gait impairment in Parkinson's disease (PD) occurs early and pharmaceutical interventions do not fully restore this function. Visual cueing has been shown to improve gait and alleviate freezing of gait (FOG) in PD. Technological development of digital laser shoe visual cues now allows for visual cues to be used continuously when walking.

A direct azidomethylation reaction at the sulfur atoms of thiols with -azidomethyldisulfonimides is presented, providing a facile and efficient approach for the synthesis of azidomethylated compounds with broad substrate scope and mild reaction conditions. Under optimized conditions using -azidomethyl-bis(4-trifluoromethylbenzene)sulfonimide as the azidomethyl source, various aliphatic and aromatic thiols furnish the corresponding -azidomethyl compounds in moderate to high yields. The reaction proceeds selectively at the mercapto group, even in substrates bearing polar functional groups.

Background: The aim of this study was to establish a rat model of premature ovarian failure (POF) with cyclophosphamide (CTX), and explore the molecular basis of POF and the mechanism of Guishen-Erxian Decoction (GSEXD) to improve POF from the perspective of oxidative stress regulation of ovarian granulosa cell (OGC) DNA fragmentation.
Method: The study utilized SD rats to establish a POF model via CTX. Rats were divided into Control, POF group, three GSEXD dosage groups (low, medium, high), and a GSEXD+PI3K agonist group to assess GSEXD's therapeutic effects on oxidative stress, DNA fragmentation and ovarian damage.

Background: Despite promising preclinical results, remote limb ischemic postconditioning efficacy in human stroke treatment remains unclear, with mixed clinical trial outcomes. A potential reason for translational difficulties could be differences in circadian rhythms between nocturnal rodent models and diurnal humans.
Methods: Male C57BL/6J mice were subjected to transient focal cerebral ischemia and then exposed to remote postconditioning during their active or inactive phase and euthanized at 24 hours and 3 days.
