Human Urogenital Myiasis Caused by Lucilia sericata(Diptera, Calliphoridae) and Wohlfahrtia magnifica (Diptera,Sarcophagidae) in Markazi Province of Iran

We report a case of human urogenital myiasis in an 86-year-old rural man with a penil ulcer and numerous alive and motile larvae from urethra and glans penis. Entomological studies on adult flies showed the larvae were Lucilia sericata  and Wohlfahrtia magnifica. The clinical presentation and treatment strategies are discussed

Rosiglitazone, but Not Epigallocatechin-3-Gallate, Attenuates the Decrease in PGC-1α Protein Levels in Palmitate-Induced Insulin-Resistant C2C12 Cells

Alteration of lipid metabolism is an important mechanism for the treatment of insulin resistance. PGC-1α, a key regulator of mitochondrial biogenesis and function, plays an important role in the improvement of insulin sensitivity by increasing fatty acids β-oxidation. In the present study, the effects of epigallocatechin-3-gallate (EGCG), an anti-obesity agent and enhancer of lipid catabolism, on PGC-1α protein expression was examined and compared with anti-diabetic drug rosiglitazone (RGZ). After differentiation of C2C12 myoblasts to myotubes, insulin resistance was induced by palmitate treatment. Then the expression of the PGC-1a gene and glucose uptake were evaluated before and after treatment with RGZ and EGCG. Palmitate treatment significantly decreased PGC-1α protein expression in C2C12 cells (P 0.05), while EGCG had no significant effect on the expression of this gene (P < 0.05). RGZ and EGCG significantly improved glucose uptake (by 2- and 1.54-fold, respectively) in myotubes treated with palmitate. These data suggest that RGZ and EGCG both exert their anti-diabetic activity by increasing insulin sensitivity, but with different molecular mechanisms. This effect of RGZ, unlike EGCG, is mediated, at least partly, by increasing PGC-1α protein expression. © 2015 AOCS
