Laboratory of Vascular Physiology & Medicine

(Electrophysiology Unit & Molecular Biology Unit)

Research Focus:

Department of Physiology has established   “Laboratory of Vascular Physiology & Medicine” under the supervision of Professor Kusal Das. This laboratory is working extensively on both human and animal model to explore and understand physiological basis of clinical acumen to vascular integrity. It has a specialized 'ELECTROPHYSIOLOGY UNIT". The focus of the Vascular Physiology Lab is studying vascular function/dysfunction in healthy and diseased states, with particular emphasis on chronic cardiovascular diseases, diabetes mellitus. Additionally, vascular responses to exercise and diet are studied and influences of Yoga and life style intervention on vascular health.  A variety of techniques are utilized to examine macro- and microvascular function as well as arterial stiffness in humans and animal models. The laboratory also devout itself to carry out different research projects on environmental health, cardiovascular health, respiratory health to functional modulation in different exercise induced interventional models with their molecular signalling pathways for both human and animal. The laboratory has a ‘General’ and ‘Electro-Physiology’ unit. The laboratory takes care of critical experimental protocol on rats and mice where cardiovascular, vascular, respiratory and neurological different parameters can be analyzed by both non invasive and invasive conditions. Laboratory is also capable to evaluate various cardiovascular histological analysis with the help of specialized software. The Laboratory is now under process of commissioning "MOLECULAR BIOLOGY UNIT'

The overall mission of the Vascular Physiology & Medicine Lab in the Department of Physiology is to determine the  mechanisms contributesto the development of vascular dysfunction with aging, Metabolic syndrome, diabetes, hypertension etc. Our lab uses integrative experimental approaches to assess vascular function of peripheral arteries,stiffness and hemodynamics of the arteries of human.


We have focused interest in translating basic science findings with experimental models to clinically relevant treatments in humans and testing the efficacy of various pharmacological and lifestyle interventions in humans at high risk for developing cardiovascular diseases from molecule to system


Currently the laboratory has two extramural projects (DRDO, Govt of India & VGST, Govt. of Karnataka) in its credit. The Laboratory is also having a full time Junior Research Fellow, supported by DRDO, Ministry of Defence, Government of India besides an expert vascular physiologist Dr.Sartish G. Patil, Assistant Professor of Physiology. Beside this the laboratory also support in running Yoga based cardiac rehabilitation trial funded by ICMR-MRC in collaboration with Centre for Chronic Disease Control (CCDC), New Delhi.
