Silicon (Si), as a beneficial or quasi-essential element, has different effects on physiological and biochemical processes in plants. But, many greenhouse growers in Iran, especially in soilless system (hydroponic), do not use Si in their recipe and fertilization program. This experiment was conducted to assess the effects of foliar application of different Si levels (0, 50, 100 and 150 mg/L) o...
Due to wasteful use of low-quality irrigation water, many agricultural lands in arid and semi-arid regions of Iran are confronted with salinity phenomenon. Salinity decreases growth and yield of plants, therefore, ways to combat deleterious effects of soil salinity on plant growth should be sought. One of these strategies is physiological prevention of salt accumulation in plants and increasing...
OBJECTIVE Positron emission tomography (PET) with fluorodeoxyglucose (FDG) is widely used for evaluation of cancer and ischemic heart disease. Recently, increased myocardial FDG uptake has been reported to be related to some types of heart disease, such as sarcoidosis. However, the physiological increased FDG uptake in the heart often mimics the abnormal high uptake in these cases. In this stud...
abstract drought is the most important factor limiting crop yield word wide. osmotic adjustment (oa) and strong and deep root system result in increased cereal drought tolerance through increasing water uptake and water use efficiency. the impact of root structure and physiological traits on drought stress response was studied in three barley cultivars including yousof (drought tolerant), moroc...
Addition of physiological concentrations of 20 l-amino acids to the incubation medium facilitates the uptake of copper by liver slices. This effect can be observed in a wide range of initial concentrations of copper in the medium, including the low physiological concentrations. The uptake of copper was not influenced by the addition of sodium lactate or d-glucose to the incubation media. The fa...
We report the physiological characteristics and O 2 cost of running overground at ?21.1 km/h in a cohort world’s best male distance runners. provide new information on absolute relative uptake required to run 2-h marathon pace.
OBJECTIVES Positron emission tomography-computed tomography (PET/CT) with fluorine-18-fluorodeoxy-D-glucose (FDG) has evolved from a research modality to an invaluable tool in head and neck cancer imaging. However, interpretation of FDG PET/CT studies may be difficult due to the inherently complex anatomical landmarks, certain physiological variants and unusual patterns of high FDG uptake in th...
