A comprehensive strategy, including spectroscopic, molecular simulation, proteomics, and bioinformatics techniques, was employed to investigate a novel triazole, 5-(4-methoxyphenyl)-1-phenyl-1H-1,2,3-triazole, its interactions with high-abundance blood proteins, and identification of low-abundance proteins. The binding constants and thermodynamic parameters of the triazole to two high-abundance blood globular proteins, human serum albumin, and human immunoglobulin G (HIgG), were obtained by spectroscopic techniques and computational chemistry. The two-dimensional gel electrophoresis in combination with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry was employed to isolate and identify differentially expressed low-abundance proteins in human blood serum samples following exposure to the triazole.

Blood stasis-heat syndrome is one of the common syndromes of ischemic stroke, which is manifested as syndromes of blood stasis and heat during the pathological progression of patients with ischemic stroke, but there is a lack of systematic research on its biological essence. Thromboinflammation reaction is a newly proposed pathological mechanism highly associated with thrombosis and inflammatory reaction, and it refers to the fact that under the mediation of von Willebrand factor(vWF) and the kallikrein-kinin system, thrombosis and inflammatory reaction interact with each other. Activation of T cells and neutrophils further aggravates thrombosis and worsens the pathological progression of ischemic stroke.

As one of the most common air pollutants, fine particulate matter (PM) increases the risk of diseases in various systems, including the urinary system. In the present study, we exposed male and female C57BL/6J mice to PM for 8 weeks. Examination of renal function indices, including creatinine (CRE), blood urea nitrogen (BUN), uric acid (UA), and urinary microalbumin, indicated that the kidneys of female mice, not male mice, underwent early renal injury, exhibiting glomerular hyperfiltration.

Previous studies have shown that nickel sulfate (NiSO) increases autophagy in thyroid cells and tissues. As an important organ of the endocrine system, the pancreas not only contributes to the exocrine function of digestion but also has the endocrine function of regulating blood sugar. However, it remains unknown whether NiSO increases pancreatic autophagy.
