Role of NLRP3 Inflammasome in Chronic Pain and Alzheimer's Disease-A Review.
J Biochem Mol Toxicol

Department of Histology and Embryology, Faculty of Basic Medical Sciences, Hubei University of Medicine, Shiyan, People's Republic of China.
The coexistence of Alzheimer's disease (AD) and chronic pain (CP) in the elderly population has been extensively documented, and a growing body of evidence supports the potential interconnections between these two conditions. This comprehensive review explores the mechanisms by which CP may contribute to the development and progression of AD, with a particular focus on neuroinflammatory pathways and the role of microglia, as well as the activation of the NLR family pyrin domain containing 3 (NLRP3) inflammasome. The review proposes that prolonged pain processing in critical brain regions can dysregulate the activity of the NLRP3 inflammasome within microglia, leading to the overproduction of pro-inflammatory cytokines and excessive oxidative stress in these regions.

Experimental studies of chronic noise exposure in modern urban life testified about oxidative stress due to the corresponding hormones effects leading to accumulation of reactive oxygen species and endothelial dysfunction. This study aims to evaluate the protective effect of α2-adrenoblockers to modulate oxidative stress and corticosterone levels due to chronic noise exposure. To achieve this, we examined the effects of beditin (2-aminothiozolyl-1,4-benzodioxane) and mesedin (2-(2-methyl-amino-thiozolyl)-1,4-benzodioxane hydrochloride), along with changes in corticosterone, Ca2 + content, and morphological alterations in various tissues under noise-induced stress.

February 2025
Department of Orbit and Oculoplasty, Sankara Eye Hospital, Coimbatore, Tamil Nadu, India.
Purpose: To evaluate the lacrimal punctal changes in different age groups using anterior segment optical coherence tomography (AS-OCT).
Methods: A cross-sectional observational study was conducted between January 2023 and January 2024 including healthy subjects between 20 and 80 years. The selected eyes from healthy patients were divided into four age groups (21-35 years, 36-50 years, 51-65 years, 66-80 years), and lower lacrimal puncta were analyzed using AS-OCT.

An understanding of snake venom pharmacokinetics is essential for determining clinical outcomes of envenoming and developing therapeutic approaches to the treatment of envenoming, especially regarding the timing and optimal dosage of antivenom administration. (Eastern Russell's viper) envenoming causes systemic coagulopathy and severe hemorrhage including acute kidney injury. These toxic outcomes can be diminished by the administration of high quantities of Russell's viper antivenom.
