Diabetic nephropathy (DN) is one of general and common complication of diabetes, which severely affects the physical and mental health of diabetic patients. Fibroblast growth factor 1 (FGF1), an effective control agent of blood glucose, plays an effective treatment role on diabetes-induced renal injury. But the specific molecule mechanism underlying it is still unclear. Since induction of cellular stress is the main and common mechanism of diabetes-induced complication, we hypothesized that reduction of cellular stress is also the molecular mechanism of FGF1 treatment for DN...

Reactive oxygen species (ROS) impair neovascularization and perfusion recovery following limb ischemia in patients with peripheral arterial disease (PAD). Hydrogen molecules (H2) comprise an antioxidant gas that has been reported to neutralize cytotoxic ROS. The present study investigated whether H2 may serve as a novel therapeutic strategy for PAD. H2‑saturated water or dehydrogenized water was supplied to mice with experimental PAD. Laser Doppler perfusion imaging demonstrated that H2‑saturated water improved perfusion recovery, decreased the rate of necrosis, increased the capillary density in the gastrocnemius muscle and increased the artery density in the abductor muscle in the ischemic limbs, at 14 and 21 days post‑hindlimb ischemia...

The effects of propolis on blood glucose regulation and the alleviation of various complications caused by diabetes have been widely studied. The main source of propolis in the northern temperate zone is poplar buds. However, there is limited research on the antidiabetic activity of poplar buds. In order to evaluate the effect of poplar buds on type-2 diabetes, crude extract and 50% fraction of poplar buds were used to feed streptozotocin-induced type-2 diabetic mice. The results showed that 50% fraction could increase insulin sensitivity and reduce insulin resistance, as well as decrease the levels of fasting blood glucose, glycated hemoglobin, and glycosylated serum proteins in diabetic mice...

TB as the cause of uveitis varies from 0.5 to 10.5%; low sensitivity of confirmatory laboratory investigations and inconsistency of diagnostic criteria leads to paucity of data. Diagnosis requires a high level of suspicion and is often presumptive based on indirect evidences. Interferon gamma, Interleukin-2 and Neopterin are key biomarkers in immuno-regulation of Mycobacterium tuberculosis infection. The relative shift from Interleukin-2 towards Interferon gamma (Interferon gamma/Interleukin-2) is more discriminatory for active tuberculosis...
