Biochemistry and physiology of nitric oxide
Research DescriptionDr. Ma's laboratory utilizes a multidisciplinary approach ranging from physiology/pharmacology, biochemistry, molecular biology, and histochemistry to integrative research in both animal models and human studies. Working in the area of nitroglycerin pharmacology and nitric oxide (NO) physiology for two decades, his research is primarily focused on NO-cGMP signal transduction pathways and physiological studies on the following areas:
1) Biocapture of biomolecules over skin regions as a translational tool to quantify changes in biomolecules accompanied by physiological modifications and pathological alterations with diseases, and interactions between somatic meridian and visceral functions
2) Investigate the therapeutic effects and mechanisms of acupuncture, electroacupuncture, slow breathing exercises and slow breathing related mind-body practices (meditation/qigong/yoga) on pain relief, hypertension and weight control.
