We explore the extent to which string theories with higher-level gauge symmetries and non-standard hypercharge normalizations can reconcile the discrepancy between the string unification scale and the GUT scale extrapolated from the Minimal Supersymmetric Standard Model (MSSM). We determine the phenomenologically allowed regions of (kY , k2, k3) parameter space, and investigate the proposal tha...

The antitoxic and antimutagenic effect of royal jelly was assayed by a standard testing procedure on Drosophila melanogaster. The similarity of metabolic pathways between Drosophila and mammals makes the test widely applicable for detecting the impact of various potential promutagens and antimutagenic effects could be recognized accordingly. The flies were treated with the potent mutagen MMS, a...

The mitochondrial DNA diversity of 62 human population samples was examined for potential signals of population expansions. Stepwise expansion times were estimated by taking into account heterogeneity of mutation rates among sites. Assuming an mtDNA divergence rate of 33% per million years, most populations show signals of Pleistocene expansions at around 70,000 years (70 KY) ago in Africa and ...

OBJECTIVE In this study, anti-inflammatory effects of Royal Jelly were investigated by inducing renal inflammation in rats with the use of ethylene glycol. For this purpose, the calcium oxalate urolithiasis model was obtained by feeding rats with ethylene glycol in drinking water. MATERIALS AND METHODS The rats were divided in five study groups. The 1st group was determined as the control gro...

BACKGROUND The objective of the current study was to assess the effects of royal jelly supple-mentation on body weight, total daily energy and macronutrients intakes in type2 diabetic fe-males. METHODS In this randomized clinical trial, fifty female volunteers with type2 diabetes were as-signed into the supplemented (n=25) and placebo (n=25) groups, given a daily dose of 1000 mg royal jelly s...

In this paper, we study one class of Ky Fan-type inequalities, which has ties with the original Ky Fan inequality. Our result extends the known ones.

Purpose: The present study investigated the most appropriate footprint index and its related parameters for the diagnosis of flatfoot, especially in cases with mild deformity. Methods: In total, 148 footprints were recorded from 77 young women with flatfoot. Footprints were classified into three groups of mild, moderate, and sever. Footprint indexes included Sztriter-Godunov (KY), Clarke’s Ang...

The umbilical cord is a structure that provides vascular flow between the fetus and the placenta. It contains two arteries and one vein, which are surrounded and supported by gelatinous tissue known as Wharton's jelly. There are many umbilical cord abnormalities that are related to the prognosis of fetus survival and birth weight. The authors report a case of umbilical cord constriction due to ...
