Most devices require abdominal wall transgression, creating a potential for abdominal complications. The incidence and impact of these relatively underreported complications are unknown. METHODS A retrospective review was performed on 179 patients(More)
Small molecular weight G-proteins serve as fundamental signaling switches that regulate cell fates by coupling receptor activation to downstream effector pathways. H-Ras, a small molecular weight G-protein, in its active form, recruits Raf. Activated Raf via a signaling transduction pathway regulates apoptosis. Our previous studies have shown that H-Ras has(More)
