Sex differences in aristolochic acid I-induced nephrotoxicity in mice and the effect of estradiol.

Aristolochic acid I (AAI), the most prominent component of aristolochic acids and found in nearly all aristolochic herbs, has been demonstrated significant nephrotoxicity. In this study, an acute nephrotoxicity model of AAI mice was established by a single dose injection of AAI. It was observed that there are differences of the sensitivity to AAI nephrotoxicity in female and male mice, with male mice exhibiting nephrotoxic effects even at lower doses.

Actl6a regulates autophagy via Sox2-dependent Atg5 and Atg7 expression to inhibit apoptosis in spinal cord injury.

Introduction: Spinal cord injury (SCI) is a severe central nervous system disorder with limited treatment options. While autophagy plays a protective role in neural repair, its regulatory mechanisms in SCI remain unclear.

Alternative splicing of vascular calcification: Insights, opportunities, and challenges.

Vascular calcification(VC) significantly increases the risk of cardiovascular events, leading to thickening of the myocardium and arteries, coronary heart disease, heart failure, and potentially triggering myocardial infarction and sudden cardiac death. Although VC is a reversible process, there are currently no methods or medications in clinical practice that can completely reverse or cure it. The current treatment strategies primarily focus on slowing the progression of VC and exploring new diagnostic and therapeutic approaches, making the identification of early diagnostic markers for VC particularly important.

Enthalpy driven temperature-sensitive conformational changes in a metamorphic protein involved in the cyanobacterial circadian clock.

Metamorphic proteins switch reversibly between distinctly different folds often with different functions under physiological conditions. Here, the kinetics and thermodynamics of the fold-switching at different temperatures in a metamorphic protein, KaiB, involved in cyanobacterial circadian clock, reveal that enthalpy-driven the fold-switching to form fold-switched KaiB (fsKaiB) and the fsKaiB and ground-state KaiB (gsKaiB) are more dominantly at lower and higher temperatures, respectively. Thermodynamic analysis indicates that conformational and solvent entropy have opposing effects on KaiB's fold-switching.

Impact of hydrodynamic cavitation-assisted microbubble with N, CO, and air on pasting, morphological, and thermal properties of starches from different botanical origins.

Microbubble-assisted starch modification (MASM) using different gases (N, CO and air) was employed to assess the effects of hydrodynamic cavitation (HC) on various botanical starches, including potato, wheat, corn and rice. SEM showed that N- and CO- microbubbles created more pronounced holes and cracks on the starch surfaces than air-microbubbles. The hydrodynamic cavitation-assisted microbubble (HCAM) treatment significantly reduced the amorphous and crystalline structures in potato and wheat starches, with less impact observed in corn and rice.
