Stigmasterol mitigates estrogen-deficiency-induced osteoporosis through inhibition of phosphorylated p65 and MAPK signaling pathways.

Background: Osteoporosis is a pervasive bone metabolic disorder characterized by the progressive degeneration of bone microstructure. Osteoclasts are playing a pivotal role in bone remodeling and resorption. Consequently, modulating osteoclast activity, particularly curbing their overactivation, has become a crucial strategy in clinical treatments.

Synthesis of P(V)-Stereogenic Phosphorus Compounds via Organocatalytic Asymmetric Condensation.

Enantioenriched phosphorus(V)-stereogenic compounds, featuring a pentavalent phosphorus atom as the stereogenic center, are crucial in various natural products, drugs, bioactive molecules, and catalysts/ligands. While a handful of stereoselective synthetic approaches have been developed, achieving direct stereocontrol at the phosphorus atom through catalytic generation of phosphorus(V)-heteroatom bonds continues to be a formidable challenge. Here, we disclose an organocatalytic asymmetric condensation strategy that employs a novel activation mode of stable feedstock phosphinic acids by the formation of mixed phosphinic anhydride as the reactive species to facilitate further catalyst-controlled asymmetric P-O bond formations, involving a dynamic kinetic asymmetric transformation (DYKAT) process with alcohol nucleophiles via a cinchonidine-derived bifunctional catalyst.

Traditional Chinese medicine FYTF-919 (Zhongfeng Xingnao oral prescription) for the treatment of acute intracerebral haemorrhage: a multicentre, randomised, placebo-controlled, double-blind, clinical trial.

Background: There are few proven treatments for acute spontaneous intracerebral haemorrhage, and they all target reducing expansion of the haematoma. The traditional Chinese medicine FYTF-919 (Zhongfeng Xingnao) in an oral solution is comprised of several Chinese herbs that are widely used to treat patients with intracerebral haemorrhage in China on the understanding that they enhance resorption of the haematoma and reduce neuroinflammation. We aimed to provide a reliable assessment of the safety and efficacy of FYTF-919 in patients with moderate to severe acute intracerebral haemorrhage.

Insights From a Novel Splicing Variant and Recurrent Arginine Variants in the CHD3 Gene Causing Snijders Blok-Campeau Syndrome.

Snijders Blok-Campeau syndrome (SNIBCPS, OMIM#618205) is an autosomal dominant neurodevelopmental disorder attributed to pathogenic variants in the chromodomain helicase DNA binding protein 3 (CHD3) gene. To date, more than 100 individuals have been diagnosed with SNIBCPS. The syndrome is characterized by intellectual disability, global developmental delay, speech or language impediments, and dysmorphic features associated with macrocephaly.
