Expression of growth hormone (GH) and GH receptor (GHR) genes in the bursa of Fabricius of chickens suggests that it is an autocrine/paracrine site of GH production and action. The cellular localization of GH and GH mRNA within the bursa was the focus of this study. GH mRNA was expressed mainly in the cortex, comprised of lymphocyte progenitor cells, but was lacking in the medulla where lymphoc...

The uptake of the triazine herbicides, atrazine and terbutryn, was determined for two freshwater photosynthetic microorganisms, the green microalga Chlorella vulgaris and the cyanobacterium Synechococcus elongatus. An extremely rapid uptake of both pesticides was recorded, although uptake rate was lower for the cyanobacterium, mainly for atrazine. Other parameters related to the herbicide bioco...

in this study the genetic polymorphism of growth hormone (gh) gene as a candidate gene in livestock was investigated. blood samples were randomly collected from 34 alpine and 42 saanen goats. dna was extracted from blood samples and a 365 bp region of exon 5 of the gh genewas amplified by polymerase chain reaction (pcr). pcr products were analyzed using single strand conformation polymorphism (...

Proof. We consider the two cases: either g ∈ H or g ∈ G−H. Case 1 Suppose g ∈ H. Then for any gh ∈ gH, gh ∈ H. This implies gH ⊆ H. Now, let h be any element of H. Then h = (gg−1)h = g(g−1h), and g−1h ∈ H because g−1 and h are both in the subgroup H. It follows that h ∈ gH and H ⊆ gH. Therefore, gH = H. It can be similarly shown that Hg = H. This means gH = Hg and H £ G by Lemma 2.5.1 from clas...

there are numerous, often contradictory reports on the effect of growth hormone (gh) therapy on thyroid function. these reports prompted us to evaluate the impact of gh therapy on thyroid function in previously euthyroid children with gh deficiency. twenty five clinically and biochemically euthyroid children with gh deficiency were studied. a thyroid profile (t4, free t4, t3 and tsh) was perfor...

Recombinant human growth hormone (hGH) was given for 6 months or longer to 68 patients with GH deficiency, 6 with Turner's syndrome and 5 with achondroplasia, during 1986-1994 in a prospective study. The total weekly administered dose of GH was 0.6 u/kg. By random sampling, 29 of 68 GH deficient patients (42.6%) received twice weekly (2 iw) intramuscular (im) injections, 17 (25%) received ...

The growth hormone (GH) receptor (GHR) binds GH in its extracellular domain and transduces activating signals via its cytoplasmic domain. Both GH-induced GHR dimerization and JAK2 tyrosine kinase activation are critical in initiation of GH signaling. We previously described a rapid GH-induced disulfide linkage of GHRs in human IM-9 cells. In this study, three GH-induced phenomena (GHR dimerizat...

The recent shift from transplanted to wet seeded rice (Oryza sativa L.) in South East Asia has resulted in major weed problems which require more labour and energy for their control. Field experiments were conducted during 1994±1996 on a Chromic Vertisol in central Luzon, the Philippines, to study the effect of water, tillage and herbicide levels on total water use, weed growth and yield of wet...
