The green revolution fulfilled the food demand of crowded millions. From the time of green revolution to till date high yielding and fertilizer responsive varieties have evolved to increase the production per unit area. To improve the productivity only major nutrients are concentrated almost in all crops. Though the importance of micronutrient realized during past decades in most of the crops b...

ferropenia and consequent iron deficiency anemia (ida), β-thalassemia, and glucose 6-phosphate dehydrogenase (g6pd) deficiency are three main common hematological problems in iran. this study was conducted to investigate the prevalence of these problems in turkish migrating nomads in southern iran. from june to october 2006, the blood sample of 152 turkish migrating nomadic children including 7...

introduction: it is generally assumed that 50% of the cases of anemia are due to iron deficiency. the most severe consequence of iron depletion is iron deficiency anemia (ida), and it is still considered the most common nutrition deficiency worldwide. the main risk factors for ida include: inadequate iron intake, impaired absorption or transport, physiologic losses associated with chronological...

abstract background iron-deficiency anemia is a widespread public health problem with major consequences for human health especially, children. however, in a fraction of patients an underlying cause is never found during routine investigation. recent studies have suggested an association between helicobacter pylori (h. pylori) infection and iron-deficiency anemia. case presentation here is repo...

Escherichia coli K12 is being used to study the potential for adaptive evolution that is present in the genome of a single organism. Wild-type E. coli K12 do not utilize any of the beta-glucoside sugars arbutin, salicin or cellobiose. It has been shown that mutations at three cryptic loci allow utilization of these sugars. Mutations in the bgl operon allow inducible growth on arbutin and salici...

The aim of this study was to evaluate and validate the efficiency of 12C6+ irradiation of Aspergillus niger (A. niger) or mutagenesis via mixed Trichoderma viride (T. viride) culturing as well as a liquid cultivation method for cellulase production via mixed Trichoderma reesei (T. reesei) and A. niger culture fermentation. The first mutagenesis approach was employed to optimize yield from a cel...

African honey bees (Apis mellifera scutellata) dramatically changed the South American beekeeping industry as they rapidly spread through the Americas following their introduction into Brazil. In the present study, we aimed to determine if the management of European-derived honey bees (A. mellifera sspp.) could reduce the relative abundance of African-matriline drones at regional mating sites k...

The cryptic bgl operon of Escherichia coli is activated by the spontaneous insertion of mobile DNA elements. Screening of a collection of such mutations revealed insertion of the 1195-base-pair element IS5 into various positions both upstream and downstream of the bgl promoter P0. Activation of the operon was in all cases attributable to enhancement of P0 activity. Introduction of internal dele...
