to study the effect of nitrogen form and ph of nutrient solution on the uptake and concentration of fe, zn, cu and mn in roots and shoots of spinach plant, a factorial experiment was conducted with two factors including nutrient solution ph in three levels (4.5, 6.5 and 8.0) and nitrate to ammonium ratio of nutrient solution in five levels (100:0, 75:25, 50:50, 25:75 and 0:100). the experiment ...
The mechanisms of uptake of non-transferrin-bound iron by human hepatoma cells (HuH7) were investigated using 59Fe-citrate and [14C]citrate. The amount of iron associated with the cells increased linearly with time, whereas citrate uptake reached a plateau after 45 min, resulting in a cellular accumulation of iron over citrate. The cells displayed high-affinity membrane binding sites for citrat...
Background: Releasing of heavy metals in the environment caused by industrialization and urban, is a concern worldwide. Cadmium ion is toxic contaminants for Humans, Animals and plants that the maximum allowable concentration in water (0.005 mg/l) is defined by WHO. Different methods for removing heavy metals have been studied. In recent years, the use of low-cost adsorbent for removal of these...
BACKGROUND Increased levels of inflammation markers, such as C-reactive protein (CRP) and tumor necrosis factor-alpha , have been found in insulin resistance syndrome. Those with elevated levels of high-sensitive CRP (hs-CRP) are at a higher risk for coronary heart disease. In the present study, we evaluated whether maximum oxygen uptake and insulin resistance are related to hs-CRP for the prim...
OBJECTIVE The aim of this optimization study was to minimize the acquisition time of 68Ga-HBED-CC-PSMA positron emission tomography/magnetic resonance imaging (PET/MRI) in patients with local and metastatic prostate cancer (PCa) to obtain a sufficient image quality and quantification accuracy without any appreciable loss. METHODS Twenty patients with PCa were administered intravenously with t...
