Traditional medicines are recently being focused on to treat diabetes and its complications because of their lack of toxic and/or side effects. This report describes the effects of 7-O-galloyl-D-sedoheptulose (GS), a polyphenolic compound isolated from Corni Fructus, on type 2 diabetic db/db mice with hepatic and pancreatic damage. We examined several biochemical factors and oxidative stress- and inflammation-related markers. In the serum, levels of glucose, leptin, insulin, C-peptide, resistin, tumor necrosis factor-α, and interleukin-6 were down-regulated, while adiponectin was augmented by GS treatment...

Docosahexaenoic acid (DHA; 22:6n-3), an n-3 polyunsaturated fatty acid, has various important roles in brain functions. Nitric oxide (NO) produced by neuronal NO synthase (nNOS) and Ca2+ /calmodulindependent protein kinase II (CaMKII) is also involved in brain functions. We investigated the influence of DHA on nNOS and CaMKII protein expression in differentiated NG108-15 cells. NG108-15 cells were seeded in 12-well plates, and after 24 h, the medium was replaced with Dulbecco's modified Eagle's medium containing 1% fetal bovine serum, 0...

Diminished ovarian reserve (DOR) refers to the decline in fertility caused by the loss of normal ovarian function. DOR is associated with adverse reactions to ovarian stimulation during in vitro fertilization and embryo transfer (IVF-ET), increasing cycle cancellation rates and reducing pregnancy rates. Although it is well known that dehydroepiandrosterone (DHEA) can be used as a dietary supplement for age-related diseases, its potential has gradually been shown for many diseases. In this review, we focus on the effects of DHEA on DOR, briefly analysing its clinical benefits and limitations and describing the mechanism of function and the clinical trials conducted...

Tuberculosis (TB) is a major public health problem that causes millions of deaths in humans around the world, and the bacterial pathogen Mycobacterium tuberculosis (Mtb) is responsible for this disease. Evidence suggested that the inflammasome-pyroptosis pathway is crucial for preventing Mtb infection. Uncertainty exists regarding whether and how these infections can bypass this immune system by Mtb. A recent Science article by Chai et al. (doi: 10.1126/science.abq0132) revealed a novel role by a eukaryotic-like effector called PtpB during Mtb infection...

Intravenous infusion using a peripheral intravenous catheter (PIVC) is often complicated by catheter failure (CF). We hypothesized that catheterization of an upper arm vein instead of a forearm vein may help prevent CF. This study was designed to compare the incidence of CF in patients receiving hyper-stimulant drugs when catheters are placed in the forearm using short PIVCs (SPCs) with that when catheters are placed in the upper arm using the new long PIVCs. Patients admitted to a university hospital in Tokyo, Japan were enrolled in this study and were assigned to the SPC or the new long PIVC group...

Increasing incidences of resistance to antibiotics by pathogenic bacteria is a worldwide concern and isolation of antibiotic-resistant strains of Niallia circulans (formerly known as Bacillus circulans), an opportunistic human pathogen, has been reported. Due to their lack of ethical constraints as well as their cost-effective rearing, invertebrates have been commonly used to study infection by bacteria pathogenic to humans. In this study, we demonstrate that a foodborne strain of N. circulans kills larvae of the silkworm, Bombyx mori within 48 h after hemolymph injection...
