The non-H atoms of the cation of the title salt, C(8)H(9)N(4)O(+)·Cl(-), are approximately co-planar (r.m.s. deviation = 0.024 Å) with one amino group forming an intra-molecular hydrogen bond to the tertiary N atom of the benzoxazole fused-ring system. The cations and anions are linked by cyclic R(2) (1)(6) N-H⋯Cl hydrogen-bonding associations, generating linear chains running along the a-axis direction.

BACKGROUND This study aimed to analyze the risk factors of central nervous system (CNS) infection caused by reactivation of varicella zoster virus (VZV) and provide reference for the prevention and early diagnosis of VZV-associated CNS infection. MATERIAL AND METHODS A prospective study was conducted on 1030 patients with acute herpes zoster (HZ) admitted to our hospital from January 2021 to June 2023. According to clinical manifestations and auxiliary examinations, they were divided into HZ group of 990 patients and VZV-associated CNS infection group of 40 patients.

Abdominal aortic aneurysm is a potentially fatal vascular inflammatory disease characterized by infiltration of various inflammatory cells.The GABA-A receptor is expressed in many inflammatory cells such as macrophages and T cells and has anti-inflammatory and antioxidant effects. Therefore, the GABA-A receptor may become a potential therapeutic target for abdominal aortic aneurysms.

Infertility affects 10-12 % of couples worldwide, 50 % of which are male. Abnormal spermatogenesis is among the main causes of male infertility. We were curious about the possible role of transmembrane channel-like protein 7 (TMC7) in spermatogenesis because of its aberrant expression in several male infertility patients.

The chloride transporter-channel SLC26A9 is mediated by a reciprocal regulatory mechanism through the interaction between its cytoplasmic STAS domain and the R domain of CFTR. In vertebrate Slc26a9s, the STAS domain structures are interrupted by a disordered loop which is conserved in mammals but is variable in non-mammals. Despite the numerous studies involving the STAS domains in SLC26 proteins, the role of the disordered loop region has not been identified.

Microplastics (MPs) are ubiquitous and are increasing globally, but there is limited information available on their presence in freshwater ecosystems. This research work aims to investigate the abundance, sinking behavior, and risk assessment of MPs in the freshwater River Basantar, Jammu & Kashmir, India. Microplastic abundance in sediments was recorded in the range of 1-6 items g, with a mean abundance of 3 ± 1.
