Urology Research Laboratory has been officially established in 1996 with commitment of the late Dr. Camille Mallouh, former Chairman and Emeritus Professor. Sensuke Konno, Ph.D., is an Associate Professor and the full-time Research Director, who has been conducting the multifaceted research projects since 1996. Dr. Konno and the urology residents have published 36 papers in the prestigious journals, made 69 presentations at the major national and international meetings and conferences, and also won over 15 awards and prizes in those meetings/conferences.
Research Projects
The followings are the current (on-going) research projects being performed under Dr. Konno’s supervision:
Critical role of oxidative stress in nephrolithiasis and its potential prevention with specific antioxidants
Prevention of renal ischemic/reperfusion injury with conventional and alternative approaches and their possible mechanisms
Assessment of possible insulin-like activity of SX-fraction (mushroom extract) with hypoglycemic effect: Prophylactic modality of diabetic nephropathy
Possible improvement of chemotherapeutic efficacy with “complementary” agents in the prognostic status of urological cancers (including prostate, bladder and renal cell carcinomas)
Investigation of the molecular basis of urological malignancies and exploration of the improved therapeutic modalities with alternative or unconventional agents (e.g., vitamin C, 2-deoxy-glucose, beta-glucan, proanthocyanidin etc.)
