PURPOSE Refraction in the peripheral visual field is believed to play an important role in the development of myopia. The purpose of this study was to investigate the differences in peripheral refraction among anisomyopia, isomyopia, and isoemmetropia for schoolchildren. METHODS Thirty-eight anisomyopic children were recruited and divided into two groups: (1) both eyes were myopic (anisomyopi...

We study the problem of detecting hierarchical ties in a social network by exploiting the interaction patterns between the actors (members) involved in the network. Motivated by earlier work using a rank-based approach, i.e., Rooted-PageRank, we introduce a novel timesensitive method, called T-RPR, that captures and exploits the dynamics and evolution of the interaction patterns in the network ...

--A reliable low-power multiplier design by adopting algorithmic noise tolerant (ANT) architecture with truncated binary multiplier to build the fixed width reduced precision replica redundancy block (RPR). The ANT architecture can meet the high speed, low power, and area efficiency. To design the fixed-width RPR with error compensation circuit via analyzing of probability and statistics. Using...

Let R be the homogeneous coordinate ring of Grassmannian G=Gr(2,n) defined over an algebraically closed field k characteristic p≥max⁡{n−2,3}. In this paper we give a description decomposition R, considered as graded Rpr-module, for r≥2. This is companion to [16], where case r=1 was treated, and taken together, our results imply that has finite F-representation type (FFRT). Though it expected al...

background: syphilis is an infectious disease caused by treponema pallidum and transmitted via sexual contact, infected discharge and blood as well as vertical transmission. it causes various impacts on women during pregnancy and their newborns which results in various complications. thus, screening of syphilis is routinely performed during pregnancy. choosing to perform a specific screening te...

background: as a drug target and an antigenic agent, hiv-1 protease (hiv-1 pr) is at the center of attention for designing anti-aids inhibitors and diagnostic tests. in previous studies, the production of the recombinant protease has been faced with several difficulties; therefore, the aims of this study were the easy production, purification of the soluble form of protease in e. coli and inves...

Background.  The incidence of hepatitis C virus (HCV) infection is increasing in human immunodeficiency virus (HIV)-positive men who have sex with men (MSM). New guidelines recommend annual screening for HCV, similar to recommendations for syphilis screening with rapid plasma reagin (RPR). Methods.  This study compares the frequency of repeat HCV antibody (Ab) testing to repeat RPR testing in a...

Syphilis is a major cause of adverse outcomes in pregnancy in developing countries. Fetal death and morbidity due to congenital syphilis are preventable if infected mothers are identified and treated appropriately by the middle of the second trimester. Most pregnant women with syphilis are asymptomatic and can only be identified through serological screening. Non-treponemal tests, such as the r...

BACKGROUND In acute coronary syndrome (ACS), inflammation and redox response are associated with increased residual platelet reactivity (RPR) on clopidogrel therapy. We investigated whether clopidogrel interaction affects platelet function and modulates factors related to inflammation and oxidation in ACS patients differently responding to clopidogrel. MATERIAL AND METHODS Platelet aggregatio...
