A series of novel N-phenylbenzamide and N-phenylacetophenone compounds were synthesized and evaluated for their antiviral activity against HCV and EV71 (strain SZ-98). The biological results showed that three compounds (23, 25 and 41) exhibited considerable anti-HCV activity (IC50=0.57-7.12 μmol/L) and several compounds (23, 28, 29, 30, 31 and 42) displayed potent activity against EV71 with the...

OBJECTIVE: Low-grade systemic inflammation is associated with an increased risk of type 2 diabetes. C-Reactive Protein (CRP), an acute phase protein produced by hepatocytes, may be associated with diabetes. This study aimed to compare serum levels of CRP in women with gestational diabetes mellitus (GDM), impaired glucose tolerance test and control subjects. MATERIALS AND METHODS: In this ca...

r Prev Res betes, characterized by perturbations in insulin production and signaling, is inversely associated rostate cancer risk irrespective of stage. Obesity, a diabetes risk factor, is inversely associated with ed disease but positively associated with advanced disease. To understand the complex associaetween hyperinsulinemia and prostate cancer, we evaluated the association of plasma C-pep...

Regional exploration and identification of anomalies can be done by geochemical data resulted from stream sediments. In this paper, fractal methods of concentration-number and concentration-area were used for regional studies, and abnormalities of elements including gold, arsenic, bismuth and mercury were studied. Statistical processing of these elements took place with the help of 1063 samples...
