Diphosphene TerP = PTer (; Ter = 2,6-MesCH; Mes = 2,4,6-MeCH) and NHC (NHC = 1,3,4,5-tetramethylimidazol-2-ylidene) exist in an equilibrium mixture with the NHC -coordinated diphosphene . While uncoordinated is inert to hydrolysis, the NHC adduct readily undergoes hydrolysis to afford a phosphino-substituted phosphine oxide with the liberation of NHC . On this basis, conditions suitable for the catalytic use of NHC were identified. Similarly, while the hydrogenation of free diphosphene with HN·BH is very slow, reacts instantaneously with HN·BH at room temperature to afford a dihydrodiphosphane.

The gut microbiota plays a pivotal role in anxiety regulation through pathways involving neurotransmitter production, immune signaling, and metabolic interactions. Among these, gut-derived serotonin (5-hydroxytryptamine, 5-HT), synthesized from tryptophan metabolism, has been identified as a key mediator. However, it remains unclear whether specific microbial factors regulate tryptophan metabolism to influence 5-HT production and anxiety regulation.

Although therapies based on direct-acting antivirals (DAAs) effectively eradicate hepatitis C virus (HCV) in patients, there is still a high risk of liver fibrosis even after a sustained virological response. Therefore, it is of great clinical importance to understand the mechanism of potential factors that promote liver fibrosis after virological cure by treatment with DAAs. Here, we found that tubulointerstitial nephritis antigen-like 1 (TINAGL1) is significantly increased in HCV-infected hepatocytes and in the liver of patients with liver fibrosis, and that higher TINAGL1 expression persists in HCV-eradicated hepatocytes after treatment with DAAs.

As a leading cause of morbidity and mortality, fibrosis is the common pathway of various chronic inflammatory diseases in organs and causes death in a large number of patients. It can destroy the structure and function of organs and ultimately lead to organ failure, which is a major cause of disability and death in many diseases. However, the regulatory mechanism of organ fibrosis is not well clear and the lack of effective drugs and treatments, which seriously endangers human health and safety.

Heart failure is characterized by abnormal β-adrenergic receptor (β-AR) activation and mitochondrial dysfunction. In heart failure, overactivation of β-AR mediates key pathological processes in cardiomyocytes, including oxidative stress, calcium overload and metabolic abnormalities, which subsequently lead to inflammation, myocardial apoptosis and necrosis. Mitochondria are the core organelles for energy metabolism, and also play a vital role in calcium homeostasis, redox balance and signaling transduction.

Oligoasthenoteratozoospermia (OAT) is a frequent but severe type of male infertility. As one of the most multifaceted male infertility resulting from sperm problems, its genetic etiology remains unknown in most cases. In this review, we systematically sort out the latest literature on clinical reports and animal models leading to OAT, summarise the expression profiles of causative genes for OAT, and highlight the important role of the protein transport system during spermiogenesis, spermatid cell-specific genes, Golgi and acrosome-related genes, manchette-related genes, HTCA-related genes, and axoneme-related genes in OAT development.
