Newborn gnotobiotic pigs were inoculated twice perorally (p.o.) (group 1) or intramuscularly (i.m.) (group 2) or three times i.m. (group 3) with inactivated Wa strain human rotavirus and challenged with virulent Wa human rotavirus 20 to 24 days later. To assess correlates of protection, antibody-secreting cells (ASC) were enumerated in intestinal and systemic lymphoid tissues from pigs in each ...
this study aimed at examining the effects of iranian efl learners’ anxiety, ambiguity tolerance, and gender on their preferences for corrective feedback (cf, henceforth). the effects were sought with regard to the necessity, frequency, and timing of cf, types of errors that need to be treated, types of cf, and choice of correctors. seventy-five iranian efl students, twenty-eight males and forty...
rotavirus is a common infection causing 450,000 deaths annually primarily in children 5 years and below. despite the high burden of disease, little is known about the epidemiology of rotavirus in libya. the aim of this study was to estimate the rotavirus disease burden among libyan children.a cross-sectional study was carried out prospectively among children 5 years old and below between august...
6 Group A rotavirus is one of the most common causes of severe diarrhoea in 7 human infants and newborn animals. Rotavirus virions are triple layered particles. The 8 outer capsid proteins VP4 and VP7 are highly variable and represent the major 9 neutralizing antigens. The inner capsid protein VP6 is conserved among group A 10 rotavirus, is highly immunogenic and is the target antigen of most i...
Introduction: In developing countries, rotaviral diarrhea is the cause of death of many children, and is the main etiology of gastroenteritis in children under 2 years old. Determination of the prevalence of rotaviral infection can reveal the impact of this infection in this group of the population and provides clues as to the strategies for prevention and treatment protocols for children s...
Enzyme-linked immunosorbent assays were developed for the detection of group B rotavirus antigen and antibody. The specificities of both assays were evaluated for antigens and serum specific for rotavirus groups A to D. Serum collected in the United Kingdom from different animal species exhibited the following high prevalence of group B rotavirus-specific antibody: pigs, 97%; cattle, 71%; sheep...
abstract the main purpose of this study was to investigate whether there was any significant difference between the speaking achievement of learners who were trained by means of consciousness raising of sociolinguistic skills and that of learners who were trained without the above mentioned task. the participants of this study consist of 60 intermediate level students participating languag...
this thesis attempts to measure learning styles, self efficacy and intrinsic motivation as predictors of iranian ielts reading comprehension. in order to address this issue, a quantitative study was conducted on some randomly selected intact students at ferdowsi university. these two groups were assigned as they were undergraduate (ba=91) and graduate (ma =74) students; they were all aged betwe...
BACKGROUND Group A rotaviruses are the most common causative agent of acute gastroenteritis among children less than 5 years of age throughout the world. This sentinel surveillance study was aimed to obtain baseline data on the rotavirus G and P genotypes across Turkey before the introduction of a universal rotavirus vaccination program. METHODS Rotavirus antigen-positive samples were collect...
background and objective: despite consistent evidence that probiotics reduce the duration of diarrhea, there is only weak evidence for their efficacy in reducing the duration of hospitalization. another source of heteroge-neity for probiotic trials is the type of probiotic being assessed; also, information about combined products is scarce. methods: this is a randomized, single-blind controlled...
