Prolyl Carboxypeptidase Activity Decline Correlates with Severity and Short-Term Outcome in Acute Ischemic Stroke.
Abstract Prolyl carboxypeptidase (PRCP) is an enzyme associated with cerebrovascular risk factors such as hypertension, diabetes mellitus, obesity and hyperlipidemia. We aim to evaluate the relation between serum PRCP activity and severity, evolution and outcome of acute ischemic stroke. We used a specific RP-HPLC activity assay to measure PRCP activity in serum of 50 stroke patients at admission, and at 24 h, 72 h and 7 days after stroke onset to assess correlations with stroke severity based on the National Institutes of Health Stroke scale score (NIHSS), infarct volume on brain MRI scan, stroke outcome based...

Regulation of DAPK1 by Natural Products: An Important Target in Treatment of Stroke
Neurochem Res. 2022 Jun 8. doi: 10.1007/s11064-022-03628-7. Online ahead of print.ABSTRACTStroke is a sudden neurological disorder that occurs due to impaired blood flow to an area of the brain. Stroke can be caused by the blockage or rupture of a blood vessel in the brain, called ischemic stroke and hemorrhagic stroke, respectively. Stroke is more common in men than women. Atrial fibrillation, hypertension, kidney disease, high cholesterol and lipids, genetic predisposition, inactivity, poor nutrition, diabetes mellitus, family history and smoking are factors that increase the risk of stroke. Restoring blood flow by repos...

Acute Low Dose Naltrexone Increases β-Endorphin and Promotes Neuronal Recovery Following Hypoxia-Ischemic Stroke in Type-2 Diabetic Mice
Neurochem Res. 2023 May 11. doi: 10.1007/s11064-023-03938-4. Online ahead of print.ABSTRACTDiabetic patients experience significant mortality and poor recovery following ischemic stroke. Our clinical and basic science studies demonstrate an overall immune suppression in the periphery of diabetic stroke patients, as well as within the central nervous system (CNS) of type-2 diabetic mice following hypoxia-ischemia (HI). Low doses of naltrexone (LDN) improved clinical outcomes in many autoimmune diseases by acting on opioid receptors to release β-endorphin which in turn balances inflammatory cytokines and modulates the opioi...

Neuropeptide α-Melanocyte-Stimulating Hormone Promotes Neurological Recovery and Repairs Cerebral Ischemia/Reperfusion Injury in Type 1 Diabetes
In conclusion, α-MSH is neuroprotective under hyperglycemic condition against I/R induced brain damage by its anti-inflammatory, anti-oxidative and anti-apoptotic properties. The use of α-MSH analogues may be potential therapeutic agents for diabetic stroke.PMID:34586586 | DOI:10.1007/s11064-021-03453-4
