A maltotetraose- and maltotriose-producing amylase which is stable at alkaline pHs and high temperatures was detected in the culture filtrate of a strain of Chloroflexus aurantiacus J-10-F1, a thermophilic, green, photosynthetic bacterium. The enzyme was purified to homogeneity, as demonstrated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, by means of ultrafiltration, ammonium s...
potato tuberworm, phthorimaea operculella zeller (lepidoptera; gelechiidae) is a worldwide pest of solanaceous crops. larvae feed inside galleries in foliage, stems and tubers making chemical control unsuccessful, so other control methods should be applied. in recent years many plants have received genes that encode toxic proteins as a strategy to resist insect pests. in this study, optimal ph ...
saluk mount is selected for devonian biostratigraphy. this area located at southwest of bojnurd. in this study three sections are selected and two sections, chahar-borj and tabar sections with a thickness of 650 m, which consist mainly of calcareous sediments was studied in detailed but third section, qelli section, with a thickness of about 450m which consist mainly of sandstone and evaporates...
We tested the hypothesis that overweight/obese men aged 50-70 years will have a greater salivary cortisol, salivary alpha amylase and heart rate (HR) responses to psychological stress compared with age matched lean men. Lean (BMI=20-25 kg/m(2); n=19) and overweight/obese (BMI=27-35 kg/m(2); n=17) men (50-70 years) were subjected to a well-characterised psychological stress (Trier Social Stress ...
OBJECTIVE The goal of this study was to assess the knowledge of pediatric hospitalists (PHs) in identifying and managing rare events during procedural sedation (PS) with ketamine and nitrous oxide (N2O). METHODS A Web-based survey with multiple choice questions and case scenarios was used to determine the knowledge of PHs in identifying infrequent contraindications and managing laryngospasm, ...
Introduction: This study was designed with the main purpose of examining the compatibility of the two indicators of wet bulb globe temperature (WBGT) and predicted thermal strain (PHS) in assessing the environmental conditions and the heat load imposed on the subjects. Method: In this cross-sectional study, 163 bakers were included in the study. Thermal stress was determined using the WBGT and...
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...
AIM To validate plant species for hypoglycaemic activity. MATERIALS AND METHODS Four plants were investigated for hypoglycaemic activity by evaluating inhibiting effects on carbohydrate-hydrolising enzymes: alpha-glucosidase and alpha-amylase. Acetone plant extracts were screened against C2C12 myocytes, 3T3-L1 preadipocytes and Chang liver cells by measuring glucose uptake. Cytotoxicity was d...
information about chronic obstructive pulmonary diseases (copd)-related health resources allocation in china is very limited. the aim of the study was to explore the distribution of copd-related health resources allocation among different levels public hospitals (phs) in hunan province of central south china.we randomly collected data from 57 public hospitals (phs) at 3 different levels in huna...
