abstract poor reading comprehension can result in failure in using references, benefiting from professional gatherings and resources, keeping up with the growing body of knowledge in the virtual world of the internet, and failing to achieve in efl programs. the purpose of the present quasi-experimental study was to explore the effects of background knowledge and previewing narrative and expos...
Rats were drowned in fresh water collected from a river, and kept immersed in the water for four weeks in separate bottles. When five rats were placed outside in the shade, where the temperature varied from 1 to 9°C, carboxyhemoglobin (HbCO) saturations in the blood and thoracic cavity fluid were not more than 1% and 10% respectively. When fifteen rats were immersed at S-9°C, HbCO saturations i...
Background and purpose: Etiology of rheumatoid arthritis is not fully recognized. The purpose of this study was to use universal and specific primers to trace bacteria in the blood and synovial fluid in patients with rheumatoid arthritis. Materials and methods: In this experimental study, a PCR method was developed to identify a wide range of bacteria in general and Staphylococcus aureus in sp...
Total body water (TBW) is consistently 70% of the lean body weight across age and sex ranges but varies as a percentage of actual bodyweight between groups and individuals owing to varied deposition of adipose tissue, which contains less water than muscle. TBW is 75% of total body weight in neonates, 70% in infants and 45% in the elderly. The average adult male (70 kg) has 60% of total body wei...
Background: There are many controversies reported about the association between blood lead levels and blood pressure among lead exposed workers. Studies have suggested incorporating lifestyle factors along with blood lead levels. The present study aimed to evaluate the effect of lead exposure on blood pressure changes among lead exposed workers in contemplation of lifestyle factors. Mater...
The purposes of this review are to show pathophysiological mechanisms for heat illness during working in a hot environment and accordingly provide some preventive considerations from a viewpoint of body fluid homeostasis. The incidence of the heat illness is closely associated with body temperature regulation, which is much affected by body fluid state in humans. Heat generated by contracting m...
BACKGROUND To assess the relation between occupational lead exposure and elevated blood pressure with consideration of a possible confounding effect by noise exposure. MATERIALS AND METHOD Some 112 male and 110 female workers at two lead battery manufacturing factories were recruited for this 1992 study in Taiwan. Study participants received regular physical examinations, including standard m...
chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...
Background and purpose: Despite the rapid development of assisted reproduction techniques (ÂRT) in recent years, implantation rates after replacement of embryos into the uterine cavity remains low. Ân important approach to improve embryo quaility and implantation rates has been the use of coculture systems. Hence this study was undertaken to evaluate the influence of cumulus cells monolayer i...
during 2010-2011 a faunistic survey was carried out for collection and identification of edaphic mesostigmatic mites (acari: mesostigmata) in jiroft and suburb. mites were extracted from soil samples by berlese funnel. the mites were cleared in nesbit fluid and were mounted in hoyer medium on microscopic slides. in this study 43 spices from 26 genera and 16 families were collected and identifie...
