Role of programmed cell death in mammalian ovarian follicular atresia.

Programmed cell death (PCD) is a fundamental process in the development process of organisms, including apoptosis, autophagy, ferroptosis, and pyroptosis. In mammalian ovaries, 99 % of follicles undergo atresia, while only 1 % mature and ovulate, which limits the reproductive efficiency of mammals. The PCD process is closely related to the regulation of follicle development and atresia.

Jingfang Granule promotes the tricarboxylic acid cycle to improve chronic fatigue syndrome by increasing the expression of Idh1 and Idh2.

Ethnopharmacological Relevance: Chronic fatigue syndrome (CFS), as a complex, multisystemic, and multisystemic disorder affecting multiple organs and systems, often accompanies by symptoms such as post-exercise discomfort, sleep disorders, cognitive difficulties, and orthostatic intolerance. Jingfang Granule (JFG) is a traditional Chinese medicine that have significant protective effects on CFS, but the mechanism is still vague.

Aim Of Study: This study was designed to evaluate the protective mechanism of JFG on mice with CFS.

Magnetic nanoparticle-mediated non-invasive imaging and eradication of lymph nodes.

Regional lymph node (LN) dissection is often used for the treatment of deep LNs in tumour surgery; however, the method is prone to incomplete LN dissection, trauma, complications, and other side effects. LN tracers make it easier to visualise and remove LNs. However, the current common LN tracers only have a single function or have radiation hazards related to their use.

Vitamin D supplementation may be beneficial in improving the prognosis of patients with sepsis-associated acute kidney injury in the intensive care unit: a retrospective study.

Background: Vitamin D, an essential fat-soluble micronutrient, exerts diverse physiological effects including the regulation of calcium ion homeostasis, modulation of immune response, and enhancement of resistance against infectious pathogens. Empirical investigations have elucidated an association between inadequate levels of vitamin D and adverse clinical outcomes in critically ill cohorts, with a noteworthy prevalence of vitamin D deficiency observed among patients afflicted with acute kidney injury (AKI). In the context of this retrospective inquiry, our aim was to assess the potential correlation between vitamin D supplementation administered during admission to the intensive care unit (ICU) and the improvement of outcomes specifically in cases of severe AKI.

Trehalose Alleviates D-Galactose-Induced Aging-Related Granulosa Cell Death in Ovaries.

Ovarian dysfunction caused by aging restricts female reproductive capacity and is accompanied by oxidative stress and impaired autophagy. Recent studies have shown that trehalose (Tre) can activate autophagy and have antioxidant effects. However, whether Tre can be used to attenuate ovarian aging remains unclear.
