conclusions dental academics were unsure about the means of infection and prevention against hbv. many of them had not completed the immunization scheme and did not have the test of seroconversion. the serological analysis revealed unprotection, even after students completed the vaccination schedule. results of the 179 students surveyed, 58.1% knew about the degree of virulence of the hepatitis...

objective: evidence shows periodontally infected patients may be at a higher risk of thrombotic accidents and adverse pregnancy outcomes, via induced systemic inflammatory mediators' production. some authors have concluded that increase in systemic inflammatory markers occurs together with increase in serum levels of auto antibodies including anti-cardiolipin antibody (acla). the aim of the pre...

objective: a descriptive study was carried out to determine the significance of igg-affinity in the serological diagnosis of rubella infections in pregnancy. materials and methods: a total of 92 pregnant women who had never received antirubella vaccines were recruited by simple random selection and did not exceed 24 weeks of gestation were recruited from the antenatal clinics of the university ...

The complex Ginzburg–Landau (CGL) equation on a one-dimensional domain with periodic boundary conditions has a number of different symmetries, and solutions of the equation may or may not be fixed by the action of these symmetries. We investigate the stability of chaotic solutions that are spatially periodic with period L with respect to subharmonic perturbations that have a spatial period kL f...

While mature splenic B cells are surface (s)IgM+ and sIgD+, immature, tolerance-susceptible B cells express sIgM and varying levels of sIgD. Differential expression of sIgD on tolerance-susceptible and resistant B cells suggests that sIgM and sIgD may transmit qualitatively different signals. Alternatively, tolerance sensitivity may be associated with intrinsic differences in sIg signaling, reg...

A modification of an assay for intercellular adhesive specificity is described. The method involves the collection of radioactively labeled cells by aggregates of the same (isotypic aggregates) or different (heterotypic aggregates) types of tissue and determination of the number of cells collected by liquid scintillation counting. The use of (32)P to label the tissues permitted a much more rapi...

The title salt, (C2H8N)2[Co(H2O)6)](SO4)2·2H2O, is isotypic with (C2H8N)2[Ni(H2O)6)](SO4)2·2H2O. The Co-O bond lengths in the [Co(H2O)6](2+) complex cation show very similar distances as in the related Tutton salt (NH4)2[Co(H2O)6)](SO4)2 [average 2.093 (17) Å], but are significantly longer than in the isotypic Ni(II) compound (Δd ≃ 0.04 Å). The cobalt cation reaches an overall bond-valence sum ...

In the crystal structure of Na2SeO3·5H2O [disodium selen-ate(IV) penta-hydrate], two Se, two selenite O atoms and one water O atom are located on a mirror plane, and one water O atom is located on a twofold rotation axis. The coordination of one Na(+) cation is distorted trigonal bipyramidal, formed by three equatorial H2O ligands and two axial selenite O atoms. The other Na(+) cation has an oc...

Tubulins, as the major structural component of microtubules (MT), are highly conserved throughout the entire eukaryotic kingdom. They consist of alpha/beta heterodimers. Both monomers, at least in multicellular organisms, are encoded by gene families. In higher plants up to eight beta-tubulin isotypes, mostly differing in their very C-termini, have been described. These variable beta-tubulin C-...

objective: diabetes mellitus and thyroid disease are the two common endocrinopathies seen in adult population. studies to evaluate thyroid disorders in patients with type 2 diabetes are lacking. the aim of this study was to compare prevalence of thyroid dysfunction and autoim-munity in type 2 diabetic patients with age and sex matched non-diabetic control group. material and methods: among pati...
