OXIS International Inc (OTCBB: OXIS), a biopharmaceutical company focused on commercializing predictive biomarkers, clinical assays and neutraceutical and therapeutic products, announced that Marvin S. Hausman MD, its President and CEO, is scheduled to present at the Acumen BioFin Rodman & Renshaw 4th Annual Global Healthcare Conference on Monday, May 14, at 4:20 p.m. local time (10:20 a.m. Eastern time). Dr. Hausman is expected to present an update on the Company's L-ergothioneine (ERGO) Program, The conference is being held at the Le Meridien Beach Plaza Hotel in Monte Carlo, Monaco.

Recently, OXIS announced that its lead antioxidant compound ERGO showed dramatic results in preserving function of sperm cells undergoing freezing and thawing. These experiments were designed by an expert in equine fertility, Lisa Metcalf, MS DVM Diplomate, American College of Theriogenology and executed in independent animal fertility laboratories. ERGO increased sperm cell viability by 15-20% in pre-clinical and clinical studies as measured by total and progressive motility, when added to known cell extender preservatives in general use in the fertility field.

These results dramatically indicate new potential applications for ERGO in various fields in which cell preservation is crucial, including, but not limited to, applications involving stem cells, sperm cells, oocytes (ova), chondrocytes (cartilage), and cell cloning Oxis has filed protective patents to cover these potential new applications for ERGO.
