Quality Protein Maize (QPM) has about twice the amount of lysine and tryptophan of normal maize and hence represents an important tool of correcting its deficiency in protein quality. However, the effects of low nitrogen and drought on genetic parameters such as gene action and combining abilities of protein quantity and quality of QPM are not known. To study how these genetic parameters are af...

purpose: vision disorders are closely associated with poverty, particularly blindness. we determined the prevalence of low vision and blindness in different socioeconomic levels. our goal was determination of correlation between socioeconomic determinants and visual acuity in varamin city. methods: this community based study was done on 2737 people over the age of 50 years, living varamin city ...

To determine the effects of depleted iron stores on endurance performance and blood lactate concentration, eight active women with normal (> 26 ng/ml) and eight with low (< 12 ng/ml) plasma ferritin concentrations were studied while performing a VO2max and an endurance test (80% VO2max) on a cycle ergometer. The low ferritin group had significantly lower serum iron concentration and transferrin...

The aim of this study was to determine the clinical safety and efficacy of preoperative embolization of meningiomas with low-concentration n-butyl cyanoacrylate (NBCA). Nineteen cases of hypervascular intracranial meningiomas were treated by preoperative embolization with 14% NBCA, using a wedged superselective catheterization of feeding arteries and reflux-hold-reinjection technique. Clinical ...

Magnesium (Mg) is the second most abundant intracellular cation and is involved in numerous physiological functions, including protein folding, intracellular signaling and enzyme catalysis. It has been shown that magnesium deficiency exacerbates pulmonary airways hyper reactivity. Several studies suggest that magnesium level has no effect on asthma but others had shown a contributory effect. Be...

Smart pump concentration mistakes can lead to harm.

In order to exploit as much as possible the surfaces apt for installation of photovoltaic (PV) systems and also to keep the unit energy cost low (without increasing meaningfully capital and operation/maintenance costs), fixed low concentration systems (LCPVs) can be adopted, such systems are normally based on flat mirrors. LCPVs can be either fixed or tracked, but in this paper the fixed soluti...

In order to understand the electrochemical behavior of a living cell at a low extracellular potassium concentration, a model is constructed. The model involves only the ATP driven sodium-potassium pump, and the sodium and potassium channels. Predictions of the model fit the N-shape of the current-voltage characteristic at low extracellular potassium. The model can, furthermore, quantitatively a...
