Periodontal diseases afflict 20-50% of the global population and carry serious health and economic burdens. Chronic periodontitis is characterized by inflammation of the periodontal pocket caused by dysbiosis. This dysbiosis is coupled with an increase in the population of Treponema denticola, a spirochete bacterium with high mobility and invasivity mediated by a number of virulence factors.

Introduction: Anzi Tiaochong Fang (ATF) is a traditional Chinese medicine (TCM) Fangji widely used to treat antiphospholipid syndrome-related recurrent pregnancy loss (APS-RPL). This study aimed to identify the quality markers and elucidate the mechanisms of ATF in treating APS-RPL.
Methods: Chemical, network pharmacology, and in vitro verification were employed to identify quality markers and mechanisms of ATF.
Titanium Dioxide (TiO) Incorporation into Poly(ether sulfone) (PES) Hollow Fiber Membranes (HFMs) Improves Biocompatibility and Separation Performance for Bioartificial Kidney (BAK) and Hemodialysis Applications.

Hemodialysis and bioartificial kidney (BAK), which mimic both physical and biological functions, can significantly impact chronic kidney disease (CKD) patients. Here we report on Hollow fiber membranes (HFMs) with enhanced separation of uremic toxins along with enhanced hemocompatibility and biocompatibility that also promote the growth of kidney cells. The improvement arises from the addition of titanium dioxide (0.

Caspases are known to mediate neuronal apoptosis during brain development. However, here we show that nonapoptotic activation of caspase-3 at presynapses drives microglial synaptic phagocytosis. Real-time observation and spatiotemporal manipulation of synaptic caspase-3 in the newly established, mouse-derived culture system demonstrate that increased neuronal activity triggers localized presynaptic caspase-3 activation, facilitating synaptic tagging by complements.
