Role of Glucagon and Its Receptor in the Pathogenesis of Diabetes.

Various theories for the hormonal basis of diabetes have been proposed and debated over the past few decades. Insulin insufficiency was previously regarded as the only hormone deficiency directly leading to metabolic disorders associated with diabetes. Although glucagon and its receptor are ignored in this framework, an increasing number of studies have shown that they play essential roles in the development and progression of diabetes.

Generation of an induced pluripotent stem cell (iPSC) line from a diabetic patient with glucagon receptor (GCGR) p.W83X mutation.

Induced pluripotent stem cell (iPSC) line, SJHi001-A, was generated from a diabetic patient carrying a heterozygous c.G248A mutation in GCGR gene that generated the p.W83X.

Role of apoptosis in the Post-traumatic stress disorder model-single prolonged stressed rats.

Post-traumatic stress disorder (PTSD) is a stress-related mental disorder which occurs following exposure to traumatic events. A number of brain neuroimaging studies have revealed that PTSD patients have reduced volume and abnormal functions in the hippocampus and the amygdala. However, the pathogenesis of abnormalities in certain brain regions, as induced by PTSD, remains unclear.

[Effects of Bushen Wenyang Huayu Recipe on Expressions of HIF-1α, PHD2, and VHL in Endometriosis Rats with Shen Yang Deficiency Blood Stasis Syndrome].

Objective: To observe the effect of Bushen Wenyang Huayu Recipe (BWHR) on hypoxia inducible factor-1α (HIF-1α), proline hydroxylase2 (PHD2), von Hippel Lindau disease (VHL) suppressor gene expressions in endometriosis (EM) rats with Shen yang deficiency blood stasis syndrome (SYDBSS), and to explore the pathogenesis of EM and the mechanism of BWHR for treating EM.

Methods: Totally 50 SD rats were randomly divided into five groups, i.e.

Growth of Sb(2)E(3) (E = S, Se) polygonal tubular crystals via a novel solvent-relief-self-seeding process.

A novel solvent-relief-self-seeding (SRSS) process was applied to grow bulk polygonal tubular single crystals of Sb(2)E(3) (E = S, Se), using SbCl(3) and chalcogen elements E (E = S, Se) as the raw materials at 180 degrees C for 7 days in ethanol solution. The products were characterized by various techniques, including X-ray powder diffraction (XRD), scanning electronic microscope (SEM), transmission electronic microscope (TEM), electronic diffraction (ED), and X-ray photoelectron spectra (XPS). The calculated electrical resistivities of the tubular single crystals in the range 20-320 K were of the order of 10(5)-10(6) Omega cm for Sb(2)S(3) and 10(3)-10(4) Omega cm for Sb(2)Se(3), respectively.
