Liposomal amphotericin B (L-AMB) has the potential to cause two major adverse events, renal dysfunction and serum potassium abnormality; however, appropriate clinical management of these events remains unclear. We retrospectively analyzed data regarding 128 hematology patients who received L-AMB in our institute and examined the association between clinical characteristics and renal dysfunction or serum potassium abnormality. We found that the median weight-normalized dose of L-AMB was 2.69mg/kg and the median administration period was 16days...

BACKGROUND: Flap necrosis due to insufficient blood supply is a common postoperative complication in random pattern flaps. Stem cell therapies have emerged as promising biologics for tissue ischemia. A novel fat derived product, stromal vascular fraction gel (SVF-gel), can be prepared with lipoaspirate through simple mechanical processing, removing only the lipid content. SVF-gel enriches adipose-derived stem cells and potentially beneficial for flap necrosis. METHODS: Nude mice ischemic flaps were treated with human SVF-gel, stromal vascular fraction (SVF) cell suspension or saline (n = 10)...

The capability of biofilm formation has a major impact on the industrial and biotechnological applications of Shewanella putrefaciens CN32. However, the detailed regulatory mechanisms underlying biofilm formation in this strain remain largely unknown. In the present report, we describe a three-component regulatory system which negatively regulates the biofilm formation of S. putrefaciens CN32. This system consists of a histidine kinase LrbS (Sputcn32_0303) and two cognate response regulators, including a transcription factor, LrbA (Sputcn32_0304), and a phosphodiesterase, LrbR (Sputcn32_0305)...
