AIMS To determine whether the British 1990 growth charts are valid for cross sectional and longitudinal use in primary school children. METHODS A total of 694 children aged 7-10 years from 10 Leeds primary schools were weighed and measured annually over three years by an expert auxologist. SD scores were calculated using both the Tanner-Whitehouse (TW) and the revised British 1990 growth refe...

background: obesity is one of the known risk factors of diabetes. nowadays in parallel with industrialization of societies, changes in lifestyle and diet habits and also decreased physical activity, the prevalence of obesity is increasing. the objective of this study is to evaluate the effect of change in body weight on blood glucose disorders rate after 3 years of tehran lipid and glucose stud...

We have used two actin-binding proteins of the intestinal brush border, TW 260/240 and villin, to examine the effects of filament cross-linking and filament length on myosin-actin interactions. TW 260/240 is a nonerythroid spectrin that is a potent cross-linker of actin filaments. In the presence of this cross-linker we observed a concentration-dependent enhancement of skeletal muscle actomyosi...

Achieving short-distance flight helps improve the efficiency of humanoid robots moving in complex environments (e.g., crossing large obstacles or reaching high places) for rapid emergency missions. This study proposes a design flying robot named Jet-HR2. The has 10 joints driven by brushless motors and harmonic drives locomotion. To overcome challenge stable-attitude takeoff small thrust-to-wei...

Quantum dots are new types of fluorescent materials for biological labeling. As a result, QDs toxicity study is an essential requirement for future clinical applications. Therefore, the cytotoxic CdSe:ZnS quantum dots effects on some organs in mice are presented in this study. In this work, 10, 20 and 40 mg/kg doses of CdSe:ZnS quantum dots were injected to 32 adult male mice. Structural and op...

The number of isolated intersections between a smooth curve in Eu-clidean space and an arbitrary hyperplane can be majorized by a weighted sum of integral Frenet curvatures of the curve. In the complex Hermitian space one can derive a similar result for holomorphic curves but with much better weights. The proof of this result is based on a generalizationof the Milnor{FF ary theorem for complex ...
