LOCV calculation of the equation of state and properties of rapidly rotating neutron stars

In this paper, we have investigated the structural properties of rotating neutron stars using the numerical RNS code and the equation of states which have been calculated within the lowest order constrained variational approach. In order to calculate the equation of state of nuclear matter, we have used UV$_{14}$ $+$TNI and AV$_{18}$ potentials. Here, we have computed the maximum mass of the neutron star and the corresponding equatorial radius at different angular velocity. We have also computed the structural properties of Keplerian rotating neutron star for maximum mass configuration, $M_{K}$, $R_{K}$, $f_{K}$ and $j_{max}$.Comment: 7 pages, 7 figure

Development and validation of a semi-quantitative food frequency questionnaire for young school-aged children

The objective of the present study was to examine the validity for estimating energy and macronutrients intake of a newly developed picture aid, semi quantitative FFQ for Greek children and preadolescents. The two methods were found to agree in terms of mean energy intake according to the Bland and Altman method, although a trend in overestimating energy intake was found as the intake increased. Additionally, results of the Wilcoxon signed rank test revealed the similarity of the distribution in energy intake as estimated from the FFQ and the 3DD [median (IQR): 2038 (1264 - 2651) kcals for the FFQ vs. 1902 (1583 - 2324) kcals for the 3DD, p=0.33] (Table 1). Concerning macronutrients intake, according to the Bland and Altman method, although the mean difference was different than zero (all p’s <0.05), the agreement was considered adequate as the mean difference for each nutrient (with the exception of poly-unsaturated fatty acids) was < 1SD of the same nutrient intake as estimated from the reference method

Endothelial nitric oxide synthase gene Glu298Asp polymorphism and risk of preeclampsia in South East of Iran

Preeclampsia (PE) is the most serious complication of pregnancy that causes maternal and fetal morbidity and mortality. Although the exact pathophysiology of PE is unknown, a large number of studies have shown that abnormalities in nitric oxide (NO) synthesis may contribute to the development of this disorder. There are some evidences that polymorphisms of the endothelial nitric oxide synthase (eNOS) gene affect NO production and have been associated with hypertension and PE in some populations. Therefore the aim of this study was to assess the relation of the Glu298Asp eNOS polymorphism and PE in an Iranian population. We compared the frequency of the Glu298Asp polymorphism in 147 women with PE and 137 healthy pregnant control subjects by polymerase chain reaction- restriction fragment length polymorphism (PCR-RFLP) method. The frequencies of Glu298Asp genotypes were significantly different between PE women and controls (p &lt; 0.001). The frequency of Asp allele was 0.32 in PE patients and 0.20 in controls and was significantly different (p &lt; 0.001). The risk of PE was 2.4 fold in pregnant women with Asp allele. In conclusion, the Asp allele could be a risk factor for PE in South East of Iran.Key words: Nitric oxide synthase, polymorphism, preeclampsia, pregnancy
