Microbial secretions manipulate the environment and communicate information to neighbours. The secretions of an individual microbe typically act externally and benefit all members of the local group. Secreting imposes a cost in terms of growth, so that cheaters that do not secrete gain by sharing the benefits without paying the costs. Cheaters have been observed in several experimental and natural ...

Intestinal microbiota plays an important role in human health, and its composition is determined by several factors, such as diet and host genotype. However, thus far it has remained unknown which host genes are determinants for the microbiota composition. We studied the diversity and abundance of dominant bacteria and bifidobacteria from the faecal samples of 71 healthy individuals. In this ...

Cystic fibrosis (CF) is an autosomal recessive inherited disease that increases viscoelasticity of pulmonary secretions. Affected patients are required to use therapeutic aerosols continuously. The expression of ABH glycoconjugates in exocrine secretions determines the nature of part of the carbohydrates present in these secretions, allowing the classification of individuals into the so-called ...

Genetic variation in both innate and adaptive immune systems is associated with Crohn's disease (CD) susceptibility, but much of the heritability to CD remains unknown. We performed a genome-wide association study (GWAS) in 896 CD cases and 3204 healthy controls all of Caucasian origin as defined by multidimensional scaling. We found supportive evidence for 21 out of 40 CD loci identified in a ...

In view of the anomalous expression of blood group and related antigens in the gastric mucosae of patients with malignant and premalignant diseases of the stomach, and the potential clinical value of their measurement, a preliminary study has been performed on the blood group antigens A, B, H, Lea, Leb, and I(Ma) in glycoprotein rich extracts of the resting and tetragastrin stimulated gastric ...

Background: Fetal Growth restriction (FGR) is associated with thrombosis of the placenta and an increased risk of subsequent vascular disease in the mother and fetus. The products of interactions between ABO(H), Lewis and Secretor genes are also associated with thrombosis and vascular disease risk. Objectives/Methods: A prospective case-control study of mothers with a severe ...

The fucosylated ABH antigens, which constitute the molecular basis for the ABO blood group system, are also expressed in salivary secretions and gastrointestinal epithelia in individuals of positive secretor status; however, the biological function of the ABO blood group system is unknown. Gastric mucosa biopsies of 41 Rhesus monkeys originating from Southern Asia were ...

ABO blood groups and secretor status are important in clinical and forensic medicine and in relation to some diseases. There are geographic and racial differences in their frequencies, but the frequency of secretor status in different ABO blood group systems has not been determined yet. Therefore, the aim of this study was mainly to determine this point. ...

Indirect immunofluorescence studies of blood group A, H, I, and i antigens were performed on the gastric mucosae and tumor tissues of patients with gastric carcinoma, on the mucosae of patients with chronic benign gastric ulceration, and on the mucosae of infants who had died of causes other than gastrointestinal disease. The following findings were of particular interest: (1) Normal ...

We examined 138 saliva samples for the presence or absence of the blood antigens ABH using haemagglutination inhibition methodology. The outcomes of the tests were scanned and examined by special software, which used the HSV colour model, allowed setting the parameters in a way that enabled differentiation of agglutination clusters from suspensions of erythrocytes and subsequently calculated the ...

Neurofibromatosis and myotonic dystrophy have occurred in ten members of a nonconsanguineous family with a high degree of concordance. The expression of neurofibromatosis is peripheral, and the expression of myotonic dystrophy has produced at least moderately severe disability. Neither disease has appeared to alter the phenotypic expression of the other when both have occurred simultaneously. ...

A47934, a peptide antibiotic produced by Streptomyces toyocaensis, belongs to the glycopeptide class of compounds which includes ristocetin and vancomycin. Incorporation studies with radioisotope-labeled substrates indicated that tyrosine, p-hydroxyphenylglycine, p-hydroxyphenylglyoxylate, acetate, and sulfate were efficiently incorporated into A47934. This is consistent with the reported ...

Percentage distributions of nine genetic markers, including ABO blood type, secretor ability, haptoglobin type, transferrin type, and group specific component type, are presented and discussed by age, sex, race, geographic region, family income and parent...

In this study intestinal and blood brain barrier (BBB) transport of ginkgolides A, B, C, J and bilobalide, isolated from Ginkgo biloba (Family-Ginkgoaceae), was evaluated in Caco-2 and MDR1-MDCK cell monolayer models. Transepithelial transport was examined for 2 hours in both absorptive and secretor...

The gene encoding GDP-L-fucose: {beta}-D-Galactoside 2-{alpha}-Lfucosyltransferase has been cloned, and a mutation in this gene has been found to be responsible for an individual being a non-secretor. 30 figs.

The appearance of radiolesions of the mucous membrane of the middle intestine was studied in Blabera fusca (Orthoptera) irradiated with a dose of 25,000 r. The most radiosensitive cells are the regeneration cells at the moment of their differentiation in secretor elements. The irradiation does not suppress the secretion of epithelial cells. (tr-auth)
