Objective: Organophosphorus Nerve Agent, VX [(O-Ethyl S-diisopropylaminomethyl) methylphosphonothioate] compound interferes with acetylcholine signaling by targeting the AChE enzyme. Studies suggest that in nerve agents poisoning, non-cholinergic effects are also responsible for damage in peripheral tissues including long term damage in brain. Present study reports cholinergic and non-cholinergic effects of VX poisoning and their prevention by use of N-acetylcysteine (NAC) in addition to conventional antidotes atropine sulphate and 2-PAM chloride as an antioxidant.

Alzheimer's disease (AD) is the leading cause of dementia, characterized by progressive cognitive decline. Cholinesterase inhibitors are commonly used to manage symptoms but have limited efficacy as the disease progresses. Aducanumab, a monoclonal antibody targeting amyloid-β (Aβ) plaques, has emerged as a novel therapeutic approach.

The purpose of this article is to investigate the effects of walnut (Juglans regia L.) kernel pellicle on the composition and properties of enzymatic hydrolysis products of walnut meal using peptidomics and bioinformatics. In this study, a total of 3423 peptide sequences were identified in peeled walnut protein hydrolysates (PWPH) and unpeeled walnut protein hydrolysates (UWPH).

Alzheimer's disease is a neurodegenerative chronic disease with a severe social and economic impact in the societies, which still lacks an efficient therapy. Several pathophysiological events (β-amyloid [Aβ] deposits, τ-protein aggregation, loss of cholinergic activity, and oxidative stress) occurs in the progression of the disease. Therefore, the search for efficient multi-targeted agents for the treatment of Alzheimer's disease becomes indispensable.

The cholinergic deficits and amyloid beta (Aβ) aggregation are the mainstream simultaneously observed pathologies during the progression of Alzheimer's disease (AD). Deposited Aβ plaques are considered to be the primary pathological hallmarks of AD and are contemplated as promising diagnostic biomarker. Herein, a series of novel theranostic agents were designed, synthesised and evaluated against cholinesterase (ChEs) enzymes and detection of Aβ species, which are major targets for development of therapeutics for AD.
