The morphogenesis of the vertebrate hindbrain involves a transient segmentation process leading to the formation of reiterated organisation units called rhombomeres (r). A number of regulatory genes expressed with a rhombomere-specific pattern have been identified, including the gene encoding the transcription factor Krox-20, which is restricted to r3 and r5. We have previously demonstrated tha...

The distribution of capsular polysaccharide (CPS) types and subtypes (serovariants) among 121 group B streptococcus (GBS) strains from Zimbabwe was examined. PCR was used for the detection of both CPS types and the surface-anchored and strain-variable proteins Calpha, Cbeta, Alp1, Alp2, Alp3, R4/Rib, and Alp4. The R3 protein was detected by an antibody-based method using monoclonal anti-R3 anti...

Vascular endothelial growth factor (VEGF)-A is an autocrine survival factor for podocytes, which express two VEGF receptors, VEGF-R1 and VEGF-R3. As VEGF-A is not a known ligand for VEGF-R3, the aim of this investigation was to examine whether VEGF-C, a known ligand for VEGF-R3, served a function in podocyte biology and whether this was VEGF-R3 dependent. VEGF-C protein expression was localized...

OBJECTIVE To evaluate if color-coded parametric images could help subjective visual analysis and improve interobserver agreement in the evaluation of segmental contraction (SC) in CMR. BACKGROUND Routine evaluation of SC in CMR remains mostly based on visual analysis of cine loops and subsequent interobserver variability remains a potential drawback. MATERIALS AND METHODS Three short axis c...

Cyprinid herpesvirus 3 (CyHV-3), also known as koi herpesvirus (KHV), is the etiological agent of a virulent and lethal disease in common and koi carp. This study aimed to determine the genetic basis underlying the common carp immune response to the CyHV-3 virus. Two common carp lines (R3 and K) were infected with CyHV-3 by immersion. The R3 line presented a 20% higher survival rate compared to...

Op-amp in loop filter While the cases using the passive loop filter (no op-amp) are simply a matter of circuit analysis, the case using the active filter requires some explanation. This case will only be described here; the accompanying analysis can be found in the supporting MathCad documents. With the op-amp in the loop, and the filter configuration shown in Figure 1, four different noise sou...

The spaces R3 and S1 ×R2 both have a standard contact structure given by the kernel of the 1form dz−y dx, where we view the solid torus S1×R2 as R3 modulo the relation (x, y, z) ∼ (x+1, y, z). We will assume that the reader is familiar with some basic concepts in Legendrian knot theory, such as front projections, the Thurston-Bennequin number, and the rotation number; see, e.g., [8], which we w...

We make an analysis of self-similar solutions for the mean curvature flow (MCF) by surfaces revolution and ruled in R3. prove that MCF non-cylindrical R3 are trivial. Moreover, we characterize revolutions under a homothetic helicoidal motion terms generating curve. Finally, cylindrical Explicit families exact also given.

The present study deals with total R ~ + concentrations ranging from about 0.02 to 6 Mol. % ! The different types of local charge compensation centers have been investigated by means of EPR, electric field effect in EPR and ITC and it was found that : i) dipole-dipole interactions significantly modify the shape of the ITC-curves even at moderate R3+

Many proteins of two-component signal transduction systems (TCS) have domain structures that do not comply with a phosphate flow as observed in linear TCS, phosphorelays, or simple branched pathways. An example is RodK, which is essential for fruiting body formation in Myxococcus xanthus and, in addition to a sensor domain, consists of a kinase domain and three receiver domains (RodK-R1, -R2, a...
