INTRODUCTION Classic Bartter syndrome is a salt-wasting tubulopathy caused by mutations in the CLCNKB (chloride channel Kb) gene. Although growth hormone deficiency has been suggested as a cause for persistent growth failure in patients with classic Bartter syndrome, in our opinion the diagnoses of growth hormone deficiency has been unconvincing in some reports. Moreover, Gitelman syndrome seem...

Unlike other mammals, Old World primates have five growth hormone-like genes that are highly divergent at the amino acid level from the single growth hormone genes found in nonprimates. Additionally, there is a change in the interaction of growth hormone with its receptor in humans such that human growth hormone functions in nonprimates, whereas nonprimate growth hormone is ineffective in human...

barley (hordeum vulgare l.) is a model plant, as genetic and physiological studies are concerned. abiotic stresses such as drought adversely affect the growth of plants. the objective of this experiment was to identify the responsive genes to osmotic stress, using macroarray (covering 13050 genes). rna was extracted from 5 barley genotypes in stress as well as in normal conditions at 3 times of...

indole acetic acid is an important hormone that improved the growth of different plant organs such as the root under normal and stress conditions. as various studies have shown, most of rhizobacteria produce indole acetic acid and thereby contribute to the growth of plants. in this study, different rhizobacteria were isolated from different regions of iran for the assessment of their ability to...
