introduction: pulmonary arterial hypertension (pah) is a late progressive sclerodermarelated complication, which can lead to right heart failure and cor pulmonale. given that cardiac catheterization is a diagnostic method of choice for pah, and considering the high risks of this method, the purpose of this study was to evaluate the relationship between serum pro‐brain natriuretic peptide (pro‐b...

an important concern in rock mechanics is non-homogeneity as joints or fault. this noticeable feature of failures in rock is appearance of slip surfaces or shear bands, the characteristics of that are associated with deformation being concentrated in a narrow zones and the surrounding material remaining intact. adopting the joints as fractures, fractures are well known for their effects on the ...

background: n-terminal pro-brain natriuretic peptide (nt-probnp) is a sensitive biomarker for the detection of asymptomatic left ventricular (lv) dysfunction. since β-thalassemia major patients suffer from early diastolic dysfunction due to iron deposition of chronic blood transfusion, we tried to evaluate the correlation between the serum nt-probnp level and the severity of lv diastolic dysfun...

objective: this study aimed to compare the effect of using casein phosphopeptide – amorphous calcium phosphate (cpp-acp) paste, remin-pro and fluoride varnish on remineralization of enamel lesions. methods: in this experimental-in vitro study, 60 intact premolars and molars were used and flat enamel surfaces were prepared. the specimens were divided into 6 groups (n=10). after primary diagnoden...

objective(s): yu-ping-feng-san (ypfs) is a classical traditional chinese medicine that is widely used for treatment of the diseases in respiratory systems, including chronic obstructive pulmonary disease (copd) recognized as chronic inflammatory disease. however, the molecular mechanism remains unclear. here we detected the factors involved in transforming growth factor beta 1 (tgf-β1)/smad2 si...

Technological advances have made FPGAs an attractive platform for the acceleration of complex scientific applications. These applications demand high performance and highprecision floating point arithmetic. In this paper, we present a design for calculating the Lennard-Jones potential and force as is done in molecular dynamics simulations. This architecture employs IEEE 754 double precision flo...

For prime power q = p and a field F containing a root of unity of order q we show that the Galois cohomology ring H∗(GF , Z/q) is determined by a quotient G [3] F of the absolute Galois group GF related to its descending q-central sequence. Conversely, we show that G [3] F is determined by the lower cohomology of GF . This is used to give new examples of pro-p groups which do not occur as absol...

Modern financial regulation has been about the spread of market-sensitive riskmanagement systems for banks, the spill-over of this approach to other financial institutions and the retreat of regulatory ambition. There is evidence that these trends are leading to a more fragile financial system, more prone to concentration and ‘liquidity black holes’. The most glaring effects of these trends are...
