Maize (Zea mays L. cv Golden Cross Bantam T51) seedlings were grown under full sunlight or 50% sunlight in a temperature-controlled glasshouse at the temperatures of near optimum (30/25 degrees C) and suboptimum (17/13 degrees C) with seven levels of nitrate-N (0.4 to 12 millimolars). The contents of phosphoenolpyruvate carboxylase (PEPC), pyruvate orthophosphate dikinase (PPD), and ribulose-1,...

grooming behaviour is one of the important mechanisms of honeybee defence against parasitic mites. in addition to genetical characteristics, environmental conditions affect the behavioural traits of honeybee colonies. the main objective of this study was to examine the effect of temperature and humidity on the ability of honeybee workers to remove varroa mites from their body. one hundred worke...

The herbaceous perennial weed Euphorbia esula L. (Euphorbiaceae) reproduces by vegetative and sexual means, characteristics that are key to its persistence and survival. In this study, we examined environmental effects on regrowth and flowering under controlled conditions to further validate field observations and set the stage for the future identification of molecular mechanisms involved in t...

Background: Asphyxia is a perinatal accident with a high mortality rate, therapeutic hypothermia in both head or whole body was suggested as effective therapeutic methods. In this study, we compare these methods in neonates with asphyxia.Methods and Materials: 16 neonates with asphyxia in two hospitals including Alzahra(head hypothermia) and Taleghani hospital (total body hypothermia) went unde...

BACKGROUND The recommended total dietary energy intake prescribed medical nutrition therapy for obese or overweight patients with type 2 diabetes in Japan is often set at 25 kcal/kg ideal body weight (IBW)/day. This study was conducted to determine the impact of the total dietary energy intake (25 or 30 kcal/kg IBW/day) on the glycemic control, lipid profile, and satisfaction level in overweigh...

Four anaerobic sequencing batch reactors (ASBRs) were operated during a period of 988 days to evaluate the effect of temperature, ammonia, and their interconnectivity on the methane yield of anaerobic processes for animal waste treatment. During period 1 (day 0-378), the methane yield was 0.31 L CH(4)/g volatile solids (VS) for all digesters (with no statistical differences among them) at a tem...

Triticum aestivum L. and Zea maize L. are both sensitive to salinity stress which is a major problem faced by farmers today. In the present study, the effect of chitosan, a biologic elicitor under salinity stress was examined on growth parameters and biochemical markers in maize and wheat s...

Background: Groundnut bud necrosis virus (GBNV) (Tospovirus genus, Bunyaviridae family) infects the major crops of solanaceae, leguminosae and cucurbitaceae in India. Temperature is an important factor which influences the plant growth and development under diseased conditions.Objective: In the present study, we evaluated the effect of four different temp...

OBJECTIVE To systematically review the evidence for association between serum 25-hydroxyvitamin D (25-(OH)D) and OA and the effect of vitamin D therapy on OA. METHODS An English Medline, EMBASE and Cochrane Library search for vitamin D and OA from January 1980 to June 2012 was performed. Randomized controlled trials (RCTs), cohort, case-control and cross-sectional studies in adults were inclu...

BACKGROUND/PURPOSE The advice that an adequate vitamin D status can be achieved by short, casual exposure to summer sunlight is ubiquitous. This review will examine the value of this advice. METHODS The results of experimental studies on changes in serum 25-hydroxyvitamin D [25(OH)D] concentrations following ultraviolet exposure are interpreted in the context of human exposure to sunlight. ...
