We describe a very rare case of concurrent variant type 3 autoimmune polyglandular syndrome (APS) and pulmonary arterial hypertension (PAH). A previously healthy 65-year-old Japanese woman was referred to our university hospital with a 2-month history of general fatigue and hyperglycemia. Laboratory tests revealed severe hyperglycemia (plasma glucose 543 mg/dL and HbA1c 10.7%) with ketonuria (3+). Glutamic acid decarboxylase (GAD) and IA-2 antibodies were positive, and the serum C peptide level was markedly decreased to 0...

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)...
