Exploring the efficacy of (R)-PFI-2 hydrochloride in mitigating noise-induced hearing loss by targeting NLRP3 inflammasome and NF-κB pathway to reduce inner ear inflammation.

Noise-induced hearing loss (NIHL) is primarily driven by inflammatory processes within the cochlea, where noise exposure triggers the activation of the NOD-like receptor protein 3 (NLRP3) inflammasome, leading to an inflammatory cascade. The interaction between increased NLRP3 expression and NF-κB activity can further amplify cochlear inflammation. Our findings reveal that (R)-PFI-2 hydrochloride, a selective inhibitor of the SETD7 enzyme, effectively inhibits the activation of the cochlear NF-κB pathway, suppresses the release of pro-inflammatory factors, and prevents inflammasome assembly.

The conicity index, measuring body fat distribution, is crucial but under-researched in its relation to KSD and all-cause mortality. This study, using data from 59,842 participants in the NHANES (2007-2018), calculated the conicity index from waist circumference, height, and weight.

ALKBH5 promotes autophagy and progression by mediating m6A methylation of lncRNA UBOX5-AS1 in endometriosis.

Long noncoding RNA (lncRNA) and N6-methyladenosine (m6A) methylation modification have recently been suggested as potential functional modulators in ovarian endometriosis, however, the function and mechanism of m6A-modified lncRNA in ovarian endometriosis remain poorly understood. In this study, we demonstrated that lncRNA UBOX5-AS1 expression was significantly elevated in ovarian endometriosis tissue and primary ectopic endometrial stromal cells. The expression of lncRNA UBOX5-AS1, which has m6A modifications, was highly positively correlated with demethylase Alk B homologous protein 5 (ALKBH5) expression and autophagy.

Isoferulic acid facilitates effective clearance of hypervirulent Klebsiella pneumoniae through targeting capsule.

Hypervirulent Klebsiella pneumoniae (hvKP) poses an alarming threat in clinical settings and global public health owing to its high pathogenicity, epidemic success and rapid development of drug resistance, especially the emergence of carbapenem-resistant lineages (CR-hvKP). With the decline of the "last resort" antibiotic class and the decreasing efficacy of first-line antibiotics, innovative alternative therapeutics are urgently needed. Capsule, an essential virulence determinant, is a major cause of the enhanced pathogenicity of hvKP and thus represents an attractive drug target to prevent the devastating clinical outcomes caused by hvKP infection.
