Objectives: Adenosine deaminase (ADA) is a critical enzyme in the catabolism of adenosine acid during purine metabolism and plays a significant role in the diagnosis and monitoring of various diseases. This study aims to investigate the relationship between serum ADA levels and risk of diabetic foot ulcers (DFU) in patients with type 2 diabetes mellitus (T2DM), providing a clinical basis for the prevention and treatment of DFU.
Methods: A retrospective study was conducted on 2 719 T2DM patients diagnosed at the Southwest Hospital of Army Medical University from January 2019 to January 2020.

Background: Neuroinflammation and activation of the immune system can influence Alzheimer’s disease (AD) progression. This is mediated by inflammatory molecules, which exacerbate the production of β‐amyloid, the propagation of tau pathology, and neuronal loss. By measuring CSF markers of inflammation in a heterogeneous clinical cohort we found that levels of Adenosine Deaminase (ADA) and Matrix‐Metaloproteinase‐10 (MMP‐10) increase in patients with AD.

Background: Purinergic signaling is vital in various cellular processes like neuroinflammation, synaptic transmission, Aβ clearance, and tau phosphorylation regulation. This study aims to examine if SNPs in purinergic signaling genes are associated to A/T(N) status biomarkers in Alzheimer’s Disease through Genome Wide Association Studies.
Method: The SNPRelate package was used to analyze SNPs in genes related to purinergic signaling and A/T(N) markers.

Background: The effect of high consumption of psychoactive substances of codeine (CDE), tramadol (TMD), and (CNB) as concoction has been associated with altered brain cognitive and neurochemical functions. However, the understanding of the complex mechanism behind the intake of co‐administration with tramadol and codeine on both cardiac and brain function, neurotransmitters, purinergic, and antioxidant enzymes activities in the brain and heart of rats remains unreported.
Method: The measure of cognition using morris water maze (MWM) and Y‐maze tests, hemodynamic parameters namely systolic blood pressure (SBP) and heart rate (HR), acetylcholinesterase (AChE), butyl‐cholinesterase (BCHE), adenosine deaminase (ADA), arginase, catalase (CAT), superoxide dismutase (SOD) enzymes’ activities, reduced glutathione (GSH) and malondialdehyde (MDA), nitric oxide (NO) levels, in the brain and heart of CNB, TMD, and CDE exposed rats was done.
Background: The progression of diabetes mellitus (DM) has been associated with changes in brain structure and function, often referred to as “diabetic encephalopathy,” which is characterized by cognitive and neurochemical dysfunction, and identifiable structural changes in brain imaging. This study investigated the effect of Moringa leaf‐supplemented diets (MLSD) on cognition, acetylcholinesterase (AChE), adenosine deaminase (ADA) and arginase activities, reactive oxygen species (ROS), total‐thiol (T‐SH), inflammatory cytokines (TNF‐α, NF‐κB, IL‐6, and IL‐10) levels, caspase‐3 expression, and nuclear factor erythroid 2–related factor‐2 (Nrf2) levels in the brain of DM rats treated with 25 mg/kg bwt acarbose (ACA).
Method: The normal control (NC) rats and diabetic rats were grouped as follows: NC rats, untreated DM rats, DM rats plus ACA, DM rats plus ACA and 2% MLSD, and DM rats plus ACA and 4% MLSD.
