in this paper, some results of singh, gopalakrishna and kulkarni (1970s) have been extended to higher order derivatives. it has been shown that, if $sumlimits_{a}theta(a, f)=2$ holds for a meromorphic function $f(z)$ of finite order, then for any positive integer $k,$ $t(r, f)sim t(r, f^{(k)}), rrightarrowinfty$ if $theta(infty, f)=1$ and $t(r, f)sim (k+1)t(r, f^{(k)}), rrightarrowinfty$ if $th...

background : iodine deficiency produces the spectrum of iodine deficiency disorders (idds) including endemic goiter, hypothyroidism, cretinism and congenital anomalies. other factors, including goitrogens and micronutrient deficiencies may influence the prevalence and severity of idds and response to iodine supplementation. an ssociation between zinc and goiter has previously been reported. met...

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...

Interleukin-23 (IL-23), a member of the IL-12 family of cytokines, is a heterodimeric cytokine. It is composed of subunits p40 (shared with IL-12) and p19 (an IL-12 p35-related subunit) and is secreted by several types of immune cells, such as natural killer cells and dendritic cells. The IL-23 receptor is composed of the subunit IL-12Rβ1 and the IL-23-specific subunit IL-23R. The binding of IL...

Genetic lack of interleukin 12 receptor beta1 (IL-12Rbeta1) surface expression predisposes to severe infections by poorly pathogenic mycobacteria or Salmonella and causes strongly decreased, but not completely abrogated, interferon (IFN)-gamma production. To study IL-12Rbeta1-independent residual IFN-gamma production, we have generated mycobacterium-specific T cell clones (TCCs) from IL-12Rbeta...
