Reaction time measurement is an indirect index of processing capability of central nervous system and s imple means o f determining sensory motor association and performance of an individual (1). Reaction time has physiological significance and is a simple and non invasive test for peripheral as well as central neural structures (2). Reaction time is crucial for our everyday lives and requires ...
rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...
results in 12 patients (37%), human papilloma virus was detected by pcr method. in addition, there was no difference in distribution of patients with respect to affliction with human papilloma virus between high-risk and low-risk groups. there was no relationship between clinical manifestation and type of papilloma virus. materials and methods this cross-sectional study was conducted on 32 pati...
conclusions human papillomavirus 16 as a high risk hpv was found to have the highest frequency among patients with anogenital warts. results out of 54 samples, 46 (85.18%) cases showed positive results for hpv dna. a total of 26 (56.6%) samples were males and 20 (43.4%) females while eight (14.81%) showed hpv negative results. overall, 37 (80%) patients had multiple sexual partners, and nine (2...
background: seborrheic keratoses (sk) are common, benign and often multiple skin tumors with disputed etiology. a follicular origin, late onset nevoid disturbance or local arrest in maturation of keratinocytes have been proposed. human papilloma virus (hpv) has been detected in a small number of cases, particularly those from the genital region. objectives: the aim of our study was to evaluate ...

background and aims: sexually transmitted infections (stis) are of major concern to clinicians and researchers in the field of reproductive medicine. many sti pathogens cause incurable and often fatal diseases, and have been transmitted through insemination procedures. the role of herpes simplex virus in male infertility has been investigated using the sensitive methods. the aim of this study w...
car-following models, as the most popular microscopic traffic flow modeling, is increasingly being used by transportation experts to evaluate new intelligent transportation system (its) applications. a number of factors including individual differences of age, gender, and risk-taking behavior, have been found to influence car-following behavior. this paper presents a novel idea to calculate the...
purpose the purpose of the present study was to evaluate the ergogenic effect of caffeine ingestion on mood state, simple reaction time, and muscle power during the wingate test recorded in the morning on elite judoists. methods twelve elite judoists (age: 21.08 ± 1.16 years, body mass: 83.75 ± 20.2 kg, height: 1.76 ±6.57 m) participated in this study. mood states, simple reaction time, and mus...
