Systematic low-grade chronic inflammation and intrinsic mechanisms in polycystic ovary syndrome.

Polycystic ovary syndrome (PCOS) is a prevalent endocrine and metabolic disorder affecting 6-20% of women of childbearing age worldwide. Immune cell imbalance and dysregulation of inflammatory factors can lead to systematic low-grade chronic inflammation (SLCI), which plays a pivotal role in the pathogenesis of PCOS. A significant higher infiltration of immune cells such as macrophages and lymphocytes and pro-inflammatory factors IL-6 and TNF-α has been detected in PCOS organ systems, impacting not only the female reproductive system but also other organs such as the cardiovascular, intestine, liver, thyroid, brain and other organs.

Benzotrithiophene-Based Covalent Organic Frameworks with Rhenium Modified for Artificial Photosynthetic CO Reduction.

Although covalent organic framework (COF)-based photocatalysts for CO reduction reaction has been widely reported, there are still some problems such as poor visible-light absorption and low activity to realize the overall reaction of CO reduction by the artificial photosynthesis strategy. Herein, anchoring the Re carbonyl complex Re(CO)Cl in a benzotrithiophene-based COF has been synthesized for artificial photosynthetic CO reduction. The photocatalytic results demonstrate that BTT-bpy-COF-Re exhibits the highest CORR activity, achieving a rate of 110.

Adapted evolution towards flagellar loss in Pseudomonas syringae.

The flagellum is a complex molecular nanomachine crucial for cell motility. Its assembly requires coordinated expression of over 50 flagellar genes, regulated by the transcription activator FleQ. Phylogenomic analyses suggest that many non-flagellated bacterial species have evolved from flagellated ancestors by losing specific flagellar components, though the evolutionary mechanisms driving this process remain unclear.
