در عدسی چشم پستانداران، پروتئین آلفا کریستالین بیش از 50% کل پروتئین های محلول را تشکیل می دهد پروتئین آلفا کریستالین می تواند به عنوان یک مولکول چاپرون در لنز چشم عمل کند. فعالیت چاپرونی پروتئین آلفا کریستالین نقش اساسی و مهمی در جلوگیری از توده ای شدن و رسوب سایر پروتئین ها در لنز چشم ایفا می کند. این پروتئین از طریق نواحی آبگریز خود به نواحی آبگریز پروتئین های غیر طبیعی شده متصل می شود و به ...
role of serum creatinine phosphokinase in outcome prediction of intoxicated patients; a brief report
introduction: several mechanisms were introduced as causes of serum creatinine phosphokinase (cpk) raise in intoxicated patients. this study aimed to assess the relationship between serum cpk level in the first 24 hours and baseline characteristics as well as outcomes of these patients. methods: this one year retrospective cross-sectional study was conducted on all intoxicated patients, who wer...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
Introduction: Investigating the factors affecting motor development is very important in identifying the causes of motor developmental delay for parents and occupational therapists in the development of pediatric treatment. This study aims to model dynamic factors affecting fine motor development milestones of 9-12 months old infants. Method: in this study 283 children were screened by age and ...
Background: Peak Expiratory Flow Rate (PEFR) is recommended as a tool for control of asthma. The purpose of this study was to determine the normal value of PEFR in the healthy high school children in Babol, Iran. Methods: This study was conducted on 470 healthy high school children (285 girls, 185 boys with the age between 14-18 years). For the determination of PEFR we used Mini Wright Peak Flo...
Prediction bias in spirometry reference equations can arise from combining equations for different age groups, rounding age or height to integers or using self-reported height. To assess the bias arising from these sources, the fit of 13 prediction equations was tested against the Global Lungs Initiative (GLI) dataset using spirometric data from 55,136 healthy Caucasians (54% female). The effec...
Introduction: Application and correct interpretation of the 6-minute walk test (6MWT) in medical, therapeutic, and exercise settings requires normal values of the 6MWT. The aim of this study was to develop and cross-validate the 6MWT prediction equation in Iranian healthy children and adolescent males. Methods: The 6MWT and anthropometric variables were measured in 391 males (8 to 17 years old...
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
