background: doppler indices of umbilical artery are used as indicator of fetal well being. objective: to compare doppler parameters of umbilical artery including pulsatility index (pi) and resistance index (ri) in patients with preeclampsia with those of normal pregnancies and to evaluate the diagnostic characteristics of these parameters in preeclampsia. materials and methods: in a case contro...

the $k$-th semi total point graph $r^k(g)$ of a graph $g$, is a graph obtained from $g$ by adding $k$ vertices corresponding to each edge and connecting them to endpoint of edge considered. in this paper, we obtain formulae for the resistance distance and kirchhoff index of $r^k(g)$.

objective: diabetic nephropathy is a major diabetes complication. arterial resistance index (ri) may predict deterioration in kidney function. this study was designed to compare renal arterial ri in different stages of renal function according to glomerular filtration rate (gfr), serum creatinine level and proteinuria. materials and methods: in a cross-sectional study on 81 diabetic patients in...

insulin resistance syndrome, also referred to as the metabolic syndrome or syndrome x, refers to a constellation of common metabolic and cardiovascular disorders (e.g. obesity, type 2 diabetes mellitus, hypertension, and dyslipidemia), which are all cardiovascular risk factors. insulin resistance can be induced by fructose-rich diet in rats. we investigated the effect of vanadyl sulfate (0.2 mg...

the degree kirchhoff index of a connected graph $g$ is defined as‎ ‎the sum of the terms $d_i,d_j,r_{ij}$ over all pairs of vertices‎, ‎where $d_i$ is the‎ ‎degree of the $i$-th vertex‎, ‎and $r_{ij}$ the resistance distance between the $i$-th and‎ ‎$j$-th vertex of $g$‎. ‎bounds for the degree kirchhoff index of the line and para-line‎ ‎graphs are determined‎. ‎the special case of regular grap...

background: obesity is a very common disorder resulting from an imbalance between food intake and energy expenditure, and it has a substantial impact on the development of chronic diseases.  the aim of this study was to examine the association of insig2 (rs7566605) gene polymorphism with obesity and obesity associated phenotypes in north indian subjects. methods: the variants were investigated ...

increases in body mass index (bmi) are reported to influence asthma response to treatment. the aim of this study was to investigate the relationship between bmi and response to treatment in a group of patients that were referred for asthma control. effectiveness measurements in this analysis included percentage of changes in forced volume in 1 second (fev1), forced volume capacity (fvc), fev1/f...

ABSTRACT Physical activity is known to influence and regulate leptin hormone secretion, which assists in the regulation of body weight and energy homeostasis. The purpose of the present study was to investigate the effects of a single session of concurrent exercise on leptin levels and insulin resistance, until 24 h post-exercise. Ten male subjects (22.9±1.7 years) healthy volunteer perf...
