statement of the problem: a major objective of investigators is to clarify the role of metabolites in achievement of maximum tooth movement with minimal root damage during orthodontic tooth movement (otm). purpose: the aim of this study was to determine the effect of administration of thyroid hormone, prostaglandin e2, and calcium on orthodontic tooth movement and root resorption in rats. mater...

The E2 envelope glycoprotein is the primary target of human neutralizing antibody response against hepatitis C virus (HCV), and is thus a major focus of vaccine and immunotherapeutics efforts. There is emerging evidence that E2 is a highly complex, dynamic protein with residues across the protein that are modulating antibody recognition, local and global E2 stability, and viral escape. To compr...

In this work, the some collective properties of even-even Ti isotopes in A50 mass region were studied by using interacting boson model-1 (IBM-1). This study includes calculations energy levels and electromagnetic transition rates 44-48Ti 52-60Ti isotopes. The neutron number 50Ti isotope is 28, magic number, was excluded from IBM-1 calculations. First, ratios analyzed comparing typical values U...

environmental variables, including soil water content (swc), act as constraints on crop growth and productivity. therefore, open air (e0), perforated (e1) and non-perforated (e2) plastic housings were used with well-watered (w0), moderately-watered (w1) and water-stressed (w2) bush bean plants to explore the relationships between water-use efficiency (wue), carbon isotope discrimination (δ) and...

This study focused on hepatosomatic and gonadosomatic index and levels of plasma 17β-estradiol (E2), vitellogenin (Vtg) and total protein and determined the localization of Vtg in the liver during vitellogenesis in female Chalcalburnus tarichi, an endemic cyprinid species living in the Lake Van, Turkey. The levels of plasma E2, Vtg and total protein in female fish increased during vitellogenesi...

abstract relation between sexual maturity and levels of two main steroid hormones in gonads, 17- estradiol (e2) and testosterone (t) were studied by using histological and radioimmunoassay in female kutum rutilus frisii kutum during spawning season of the southern caspian sea. the study was carried out from february to may 2008 using 105 migrated fish specimens catched from the river sefid-rood...

The Heisenberg double Dq(E2) of the quantum Euclidean group $${{\cal O}_q}({E_2})$$ is smash product with its Hopf dual $${U_q}({e_2})$$ . For algebra Dq(E2), explicit descriptions prime, primitive and maximal spectra are obtained. All prime factors presented as generalized Weyl algebras. As a result, we obtain that has no finite-dimensional representations, cannot have structure. automorphism ...

Sindbis virus (SV) is an alphavirus that causes encephalitis in mice and results in age-dependent mortality. The outcome is dependent on the virus strain. Residues at 55 and 172 in the E2 glycoprotein determine the neurovirulence for mice of different ages and the efficiency of replication in the nervous system and neuronal cells. To determine the effects of these two residues on the initial st...
