  • Publication number: 20230134886
    Abstract: The presently-disclosed subject matter generally to methods for identifying and analyzing biomarkers to determine group effects. The presently-disclosed subject matter also relates to methods for identifying genes and proteins that increase or decrease in response to ischemic stroke damage. The disclosed subject matter further describes methods of predicting edema and infarct volume in a patient. Also described herein are methods of determining the necessity of intervention for smokers. Further disclosed herein, are methods for testing therapies for ischemic stroke.

  • Patent number: 9636311
    Abstract: A method of treating stroke by administration of a novel sigma agonist is presented. Twenty-four hours after MCAO, systemic administration of several novel sigma agonists including: Bromo-DTG; Chloro-DTG; N,N?-di-1-Naphthylguanidine hydrochloride (NAGH); N,N?-di-p-Nitrophenylguanidine HCL (NAD) or vehicle were injected subcutaneously daily for 3 days. Rats treated with Bromo-DTG and Chloro-DTG had no significant improvements in any of the motor or cognitive tests while NAGH treated rats showed improved vertical movement and had significantly less motor asymmetry and bias than vehicle treated rats. Sigma receptor agonist NAGH also was found to exert its long-term neuroprotective effects by preserving both gray matter and white matter tracts. Both NAD and NAGH, when administered 24 hours after experimental stroke, reduced neural damage and enhanced behavioral recovery thirty days later which suggests that NAGH and NAD potentially extend the therapeutic window of stroke several fold over the current treatments.
