Glycophorin A-deficient red cells may have a weak expression of C4-bound Ch and Rg antigens

The blood group antigens Ch and Rg are polymorphisms of C4d. Antigen-positive red blood cells (RBCs) treated with proteases type as Ch-, Rg-. Although RBCs treated with sialidase may type Ch+ Rg+, they cannot be coated with C4 by the 10 percent sucrose method. Since studies of complement binding have shown that glycophorin A (GPA) is an important component for the uptake of C4 by RBCs, we tested all available GPA-deficient RBCs for their Ch and Rg status. Using eluates of human anti-Ch and anti

The Heavy-Metal Resistance Determinant of Newly Isolated Bacterium from a Nickel-Contaminated Soil in Southwest Slovakia

A bacterial isolate MR-CH-I2 [KC809939] isolated from soil contaminated mainly by high nickel concentrations in southwest Slovakia was previously found carrying nccA-like heavy-metal resistance determinant, marked as MR-CH-I2-HMR [KF218096]. According to phylogenetic analysis of short (696 bp) 16S rDNA (16S rRNA) sequences this bacterium was tentatively assigned to Uncultured beta proteobacterium clone GC0AA7ZA05PP1 [JQ913301]. nccA-like gene product was on the same base of its partial (581 bp

An update on Rodgers and Chido, the antigenic determinants of human C4

Rodgers (Rg) and Chido (Ch) blood groups are antigenic determinants of the fourth component of human complement (C4). Nine determinants have been defined by means of hemagglutination-inhibition (HAI) with polyspecific human antiserums. The association of C4A isotypes with Rg and of C4B isotypes with Ch is strong hut not complete. Derived amino acid sequences from the C4d region of selected C4 allotypes of known antigenic expression have provided support for the previously reported complex

An update on the Chido/Rodgers blood group system

A review of the Chido/Rodgers blood group system published in 2010 summarized the discovery of this blood group,1 with the eventual recognition that Chido/Rodgers antigens were not intrinsic red blood cell (RBC) antigens but were epitopes carried on the C4 component of complement. In normal homeostasis, fragments of the C4 protein (C4b) are deposited on the RBC membrane and on other tissues as well. C4b is then broken down to C4d. Thus, with anti-Ch or anti-Rg, agglutination with indirect

Chronotype and sleep quality as a subphenotype in association studies of clock genes in mood disorders

Genetic background and clinical picture of mood disorders (MD) are complex and may depend on many genes and their potential interactions as well as environmental factors. Therefore, clinical variations, or endophenotypes, were suggested for association studies. The aim of the study was to investigate association between the chronotype (CH) and quality of sleep characteristics with polymorphisms CLOCK, ARNTL, TIMELESS and PER3 genes in MD. We included a total sample of 111 inpatients and 126

The sensitivity and specificity of CR, based on the 96 previously screened samples, was 95 percent and 90 percent, respectively, and the sensitivity and specificity of RS was 90 percent and 89 percent, respectively. Antibodies detected only by CR included anti-K(1), -Ch(2), -Jka(1), -Lea(1), -Fya(1), -Mca(1), and -e(1). Antibodies detected only by RS included anti-Jka(5) and -E(1). The sensitivity and specificity of CR for the 648 prenatal samples was 100 percent for each, while the

diversified structure and mineralogical composition makes it necessary to create extensive database of results which would enable the development of universal procedures that have not yet been created or standarized in the majority of countries. For this reason, the author of this paper completed a comprehensive research plan for three selected soils (FSa – SP, saGr – GW and siCl – CH) which includes the influence of moisture on the drying process, specimen mass, number of dried specimens and their

SEFP: A NEW ROUTING APPROACH USING FUZZY LOGIC FOR CLUSTERED HETEROGENEOUS WIRELESS SENSOR NETWORKS

with the maximum chance value becomes a cluster head (CH) based in three fuzzy parameters such as residual energy of each sensor node, closeness to base station (BS), and sum of distances between particular sensor node and other sensor nodes (area distance). The Simulation results of heterogeneous WSNs shows that our approach using fuzzy logic system always preserves more energy as compared to well-known protocols such as LEACH and SEP. additionally, we found that our approach SEFP outperforms
