the aim of this experiment was the study of dry matter and nitrogen (n) accumulation, remobilization and harvest index in different wheat cultivars. five bread wheat cultivars (darya, kuhdasht, shiroudi, tajan and zagros) and two durum wheat cultivars (arya and dena) were studied under optimum growth conditions during 2008-2009 at research field of gorgan university of agricultural sciences and...

Systemic pesticides (SPs) are usually recommended for soil treatments and as seed coating agents and are taken up from the soil by involving various plant-mediated processes, physiological, and morphological attributes of the root systems. Microscopic insights and next-generation sequencing combined with bioinformatics allow us now to identify new functions and interactions of plant-associated ...

PET/CT is widely used for the evaluation of patients with thoracic malignancies. Although the levels of 18F-fluorodeoxyglucose (FDG) uptake are usually high in neoplastic diseases, they can also be physiological, due to artifacts. In addition, FDG uptake can occur in benign conditions such as infectious, inflammatory, and iatrogenic lesions. Furthermore, some malignant tumors, such as adenocarc...

The occupancy of high-affinity ryanodine-binding sites of isolated heavy sarcoplasmic reticulum vesicles occurring in concentrated salt solutions affects ATP-dependent calcium accumulation and caffeine-induced calcium release. The initial suppression of calcium uptake is followed by a marked uptake activation resulting in a reduction of the final calcium level in the medium. Simultaneously, caf...

Introduction: The use of incremental exercise tests (IET) to evaluate the individual’s acute responses is an essential tool in Physical Activity Science.
 Objective: This paper aims analyze behavior between biochemical and physiological variables as aerobic-anaerobic transition indicators during two tests, which measure maximum oxygen uptake healthy subjects.
 Methodology: sample cons...

PURPOSE To propose a modified initial area under the uptake curve (mIAUC) dynamic contrast-enhanced (DCE)-MRI approach to achieve better distinction of underlying physiology. MATERIALS AND METHODS The mIAUC is formulated on common characteristics of tissue contrast uptake curves observed over a wide range of physiological conditions. The new metrics, IAUC(Ktrans) and IAUC(ve), are related to ...
