Context: To clarify the social issues and problems associated with burn care in Japan, based on a cost analysis of acute burn care.', 'A retrospective review was undertaken of 71 patients admitted with burns at Nippon Medical School between January 1 and December 31, 1997. A cost analysis was performed for three major burn patients with a burn surface area (BSA) of 70% to 80% and three minor burn patients with a BSA of 20% to 30%. A questionnaire was administered to both burn patients and medical providers in all 127 emergency centers to help improve long-term quality of life (QOL).', '80% of burn patients were under age 70. In the major burn cases, the amount of reimbursement according to the government-regulated fee schedule was much less than the cost of treatment. The ratio of the cost of both medication and materials to total cost of treatment was higher for patients with major burns. Patients responding to the survey acknowledged being generally happy despite suffering from psychological and financial problems. A total of 413 medical providers from 63 institutions responded to the survey regarding improving long-term QOL.
Answer: Acute burn care is a costly service. The goal of burn care should shift from saving lives to allowing for a productive return to society. Quality improvement, outcome measurement, and technology assessment combined with health economics research for burn care should be carried out in Japan.
Do the cost of burn care and implications for efficient care?

Context: To explore the role of SCF/c-Kit signaling in the invasion of bladder cancer T24 cells.', 'Western blotting was used to detect the expression of c-Kit and PI3K pathway activation stimulated by stem cell factor (SCF) in T24 cells. The invasiveness of T24 cells before and after SCF stimulation and Wortmannin (aspecific PI3K inhibitor) treatment was evaluated using Transwell invasion assay (direct and indirect counting methods).', 'T24 cells expressed c-Kit protein and showed obvious Akt phosphorylation after stimulation with SCF (1 ng/ml) for 24 h. Compared to the control group, SCF stimulation (1 ng/ml) caused a greater number of T24 cells to migrate through the polycarbonate film (P<0.01), and this effect was blocked by the application of Wortmannin before the stimulation.
Answer: SCF/c-Kit signaling promotes the invasiveness of T24 cells, and this effect is mediated by the PI3K pathway.
Does [ SCF/c-Kit signaling promote invasion of T24 cells via PI3K pathway ]?

Context: Tissue and organic venous congestion is a common pathophysiologic phenomenon. However, it is unclear whether venous congestion induces small-intestinal mucosal apoptosis. The aim of this study was to investigate whether venous congestion, or congestion followed by re-outflow, induced small-intestinal mucosal apoptosis, and whether tumor necrosis factor-alpha is involved in this apoptosis.', 'Small-intestinal venous congestion was induced in rats by occlusion of the superior mesenteric vein with a micro-bulldog clamp. At the end of the congestive period, the clamp was released to facilitate congestion followed by re-outflow. The rats were injected with a neutral anti-tumor necrosis factor-alpha antibody (0.15 mg/kg) via the jugular vein for 30 min before venous congestion or congestion followed by re-outflow. Intestinal mucosal apoptosis was evaluated and tumor necrosis factor-alpha was assayed. The amounts of caspase-8, caspase-3, and cytochrome c were determined by Western blot analysis.', 'Our results showed that venous congestion and congestion followed by re-outflow significantly increased mucosal apoptosis, the amount of mucosal tumor necrosis factor-alpha, and the levels of caspase-8 cleavage and caspase-3 activation, but did not induce cytochrome c release from mitochondria to the cytosol. Pretreatment with an anti-tumor necrosis factor-alpha antibody significantly reduced mucosal apoptosis after intestinal congestion or congestion followed by re-outflow.
Answer: The present results support the view that venous congestion and congestion followed by re-outflow induce mucosal apoptosis in the rat small intestine, and show that the apoptosis occurs partly via tumor necrosis factor-alpha-mediated cell death.

Does venous congestion induce mucosal apoptosis via tumor necrosis factor-alpha-mediated cell death in the rat small intestine?
