Molecular hydrogen (H2) can scavenge hydroxyl radical and diminish the toxicity of peroxynitrite; hence, it has interesting potential for antioxidant protection. Recently, a number of studies have explored the utility of inhaled hydrogen gas, or of hydrogen-saturated water, administered parenterally or orally, in rodent models of pathology and in clinical trials, oftentimes with very positive o...

OBJECTIVE Ghrelin is the recently identified endogenous ligand for the ghrelin receptor GHS-R1a and known to regulate growth hormone secretion and appetite. Ghrelin also is a potent vasodilator and improves cardiac performance after systemic administration. Generally, the octanoyl modification on Ser3 has been considered essential for biological activity. Recently however, cardiovascular action...

Neuronal GABA(B) receptors regulate calcium and potassium currents via G-protein-coupled mechanisms and play a critical role in long-term inhibition of synaptic transmission in the CNS. Recent studies have demonstrated that assembly of GABA(B) receptor GABA(B)R1 and GABA(B)R2 subunits into functional heterodimers is required for coupling to potassium channels in heterologous systems. However wh...

Here, we present 12 loci paternal haplotypes (Y-STR profiles) against the backdrop of the Y-SNP marker system of Bantu males from the Maputo Province of Southeast Africa, a region believed to represent the southeastern fringe of the Bantu expansion. Our Maputo Bantu group was analyzed within the context of 27 geographically relevant reference populations in order to ascertain its genetic relati...

Analysis of Y-chromosome haplogroup distribution is widely used when investigating geographical clustering of different populations, which is why it plays an important role in population genetics, human migration patterns and even in forensic investigations. Individual determination of these haplogroups is mostly based on the analysis of single nucleotide polymorphism (SNP) markers located in t...

The merozoite surface antigens MSA-2 of Babesia bovis constitute a family of polymorphic GPI-anchored glycoproteins located at the parasite cell surface, that contain neutralization-sensitive B-cell epitopes. These are therefore putative vaccine candidates for bovine babesiosis. It was previously shown that (i) the MSA-2 antigens of the biologically cloned Mo7 strain are encoded by four tandeml...

Ethnic Belarusians make up more than 80% of the nine and half million people inhabiting the Republic of Belarus. Belarusians together with Ukrainians and Russians represent the East Slavic linguistic group, largest both in numbers and territory, inhabiting East Europe alongside Baltic-, Finno-Permic- and Turkic-speaking people. Till date, only a limited number of low resolution genetic studies ...

background: polycystic ovary syndrome (pcos) is related to obesity and to major metabolic alterations including both insulin resistance and beta-cell dysfunction. ghrelin was identified as the endogenous ligand for the growth hormone secretagogue (ghs) receptor. the actions of ghrelin are carried out through interaction with specific receptor, named ghs-r. objective: in a case-control study, we...

The atmospheric chemistry of sulphuryl fluoride, SO2F2, was investigated in a series of laboratory studies. A competitive rate method, using pulsed laser photolysis (PLP) to generate O(1D) coupled to detection of OH by laser induced fluorescence (LIF), was used to determine the overall rate coefficient for the reaction O(D)+SO2F2→products (R1) of k1 (220–300 K) = (1.3±0.2)× 10−10 cm3 molecule−1...

The restricted expression of the human Fc gamma R1b gene to myeloid cells is likely to be regulated by a combination of transcription factors that may not be solely expressed in myeloid cells, but act together to restrict the expression of the gene to myeloid cells. Low basal expression of the human Fc gamma R1b gene is specifically upregulated by interferon gamma (IFN-gamma). A 181-bp region o...
