The effects of factor IX concentrate therapy on hemostasis in hemophilia patients were studied by means of the radiometric factor IXa assay, the coupled amidolytic assay for factor VIIa, and coagulant assays for factors II, IX, and X, and antithrombin III. Both activated and unactivated concentrates contained factors VIIa and IXa, with the highest levels in the activated concentrates. Factors V...

background and purpose: identifying the risk factors of hepatitis c، b، and hiv is necessary to prevent their increasing prevalence. therefore، we sought to identify the frequency of their risk factors among the homeless of tehran، iran during 2005 to 2007. methods and materials: this descriptive analytical study was conducted during 2005 to 2007 on the homeless population of tehran، iran. two ...

Purpose. To investigate the relationship between corneal biomechanical parameters, anterior segment parameters, and geometric corneal parameters in a healthy Caucasian group. Methods. This retrospective study included the healthy eyes with best corrected visual acuity of at least 20/40 of 122 Caucasian subjects. The anterior segment parameters and geometric corneal parameters such as corneal vo...

Recent assessments of structure prediction have demonstrated that (i) although fold recognition methods can often identify remote similarities when standard sequence search methods fail, the score of the top-ranking fold is not always signii-cant enough to allow a conndent prediction; (ii) the use of structural information such as secondary structure increases recognition accuracy; (iii) modern...

Background The A2A adenosine receptor is a member of the G proteincoupled receptor family. It is known to posses several unique structural and functional features that differ from established signaling paradigms. Recently, the exceptionally long (>120 amino acids) C-terminus of the receptor has raised interest for its capacity to act as a binding site for several "accessory" proteins. In search...

Nonnucleoside reverse transcriptase inhibitors (NNRTIs) are allosteric inhibitors of the HIV type 1 (HIV-1) reverse transcriptase (RT). Yeast grown in the presence of many of these drugs exhibited dramatically increased association of the p66 and p51 subunits of the HIV-1 RT as reported by a yeast two-hybrid assay. The enhancement required drug binding by RT; introduction of a drug-resistance m...

we introduce a two generated weakly branch contracting automaton group $g$ which is generated by a two state automaton on a three letter alphabet. using its branch structure and the finiteness nature of a sequence of its factor groups we compute the order of some of these factors. furthermore some algebraic properties of $g$ are detected .

We show how to calculate the zeta functions and the orders |X| of Tate-Shafarevich groups of the elliptic curves with equation Y 2 + XY = X3 + αX2 + const · T−k over the rational function field Fq(T ), where q is a power of 2. In the range q = 2, k ≤ 37, α ∈ F2[T−1] odd of degree ≤ 19, the largest values obtained for |X| are 472 (one case), 392 (one case) and 272 (three cases). We observe and d...

A two dimensional finite model with inclined crack at different crack angles are being analyzed in mixed mode condition using photo elasticity method for the determination of Stress Intensity Factors. The well-known Sih’s equation and three points deterministic approach is used for the determination of stress intensity factors. The effects of biaxial load factor, crack angle, size factors were ...
