A rapid and simple technique for diagnosis of rotaviral diarrhea is polyacrylamide gel electrophoresis (PAGE) of dsRNA extracted from fecal samples. To determine the electrophoretype of Iranian calf rotavirus, 23 rotaviral positive fecal samples from diarrheic Holstein calves at the age of less than one month in Tehran region were examined. The viral dsRNA was extracted with phenol-chloroform, ...
this study aimed to investigate the effects of listening strategy training on iranian efl learners listening comprehension and use of such strategies. this work, employing an experimental methodology, was conducted among 60 adult efl learners from a language institute in isfahan, iran, as participants. the participants, who were selected based on the results of a placement test, were assigned t...
Background and Aims: Rotaviruses are one of the main causative agents of acute viral gastroenteritis in both young human and animals. Several methods have been used for diagnosis of rotavirus infection. Most of these methods are not easily available in Iran. Methods: In our study attempt was made to develop a method which could replace the commercially imported Kit. Rota virus was purified and...

Background: Group A rotavirus (RVA) mainly causes acute gastroenteritis, exclusively in young children in developing countries. The prevalence and determination of the molecular epidemiology of rotavirus genotypes will determine the dominant rotavirus genotypes in the region and will provide a strategy for the development of appropriate vaccines. Methods: A total of 100 fecal samples ...
BACKGROUND Rotavirus is associated with acute infantile gastro-enteritis in infants and young children worldwide. Rotavirus is associated with the high cases of morbidity and mortality and it is estimated that up to 650,000 deaths in young children occur annually in the less developed countries. Approximately a quarter of these deaths occur in African children yet minimal data exist on the circ...
abstract recent studies suggest that prelistening activities play an important role in the development of listening comprehension (e.g. long 1990;chiang and dunkel 1992; schmidt-rinehart 1994; jensen and hansen 1995; robinson et al., 1995; buck, 1995; foster and skehan,1996; teng 1996; robinson, 2001; chang and read 2006). in line with previous studies and to shed light on a new aspect of sche...
Neonatal diarrhea induced by bovine group A rotavirus causes significant economic loss in the dairy and beef industry due to increased morbidity and mortality, treatment costs, and reduced growth rates. The objective of this study was to evaluate a human group A rotavirus assay (ImmunoCardSTAT Rotavirus [ICS-RV]) as an on-site diagnostic test for bovine rotavirus. When used with a collection of...
Background & objective: Rotavirus is the most important viral cause of diarrhea and dehydration, and is one of 10 important pathogens in hospitalized patients. In developed countries, the identification of rotavirus in stool is a routine diagnostic method in diarrhea to reduce the need for antibiotics. Materials & Methods: This study is a descriptive and analytical study and it consists of 400 ...
abstract the present study was conducted to investigate the effect of using model essays on the development of writing proficiency of iranian pre-intermediate efl learners. to fulfill the purpose of the study, 55 pre- intermediate learners of parsa language institute were chosen by means of administering proficiency test. based on the results of the pretest, two matched groups, one as the expe...
