In this paper, we give connection between the order of the generalized Baer-invariant of a pair of finite groups and its factor groups, when ? is considered to be the specific variety. Moreover, we give a necessary and sufficient condition in which the generalized Baer-invariant of a pair of groups can be embedded into the generalized Baer-invariant of pair of its factor groups.

BACKGROUND Fibrinogen levels are a widely accepted risk factor for cardiovascular disease, but the extent of the genetic component is unknown. MATERIALS AND RESULTS To search for these genes, we conducted a genome-wide scan using 21 Spanish families from the Genetic Analysis of Idiopathic Thrombophila (GAIT) Project. Two loci were detected: 1 on chromosome 12 and another on chromosome 14. The...

In cool temperate areas, such as Scotland, sheep are infected by a variety of nematodes but the dominant nematode is Teladorsagia circumcincta. Resistant animals have one or more of the following features: fewer adult nematodes, more inhibited larvae, shorter adult nematodes and decreased production of nematode eggs. In lambs at the end of the first grazing season, the heritability of adult wor...

Structural analysis and nanosizing of gene domains requires not only high-resolution microscopy but also improved techniques of fluorescence labelling strongly focussed on the gene domains. To investigate the architecture of abl and bcr in blood cell nuclei forming the Philadelphia chromosome in CML, we applied COMBO-FISH using specifically colocalising combinations of triple strand forming oli...

Previous studies of the HIV-1 disease have shown that HLA and Chemokine receptor genetic variants influence disease progression and early viral load. We performed a Genome Wide Association study in a cohort of 605 HIV-1-infected seroconverters for detection of novel genetic factors that influence plasma HIV-RNA and cellular HIV-DNA levels. Most of the SNPs strongly associated with HIV-RNA level...

Female extra-pair reproduction in socially monogamous systems is predicted to cause cuckolded socially-paired males to conditionally reduce paternal care, causing selection against extra-pair reproduction and underlying polyandry. However, existing models and empirical studies have not explicitly considered that cuckolded males might be related to their socially-paired female and/or to her extr...

Chronic myelogenous leukemia is characterized by the Philadelphia chromosome, which at the molecular level results from the fusion of the bcr gene on chromosome 22 and the ablgene on chromosome 9. The bcr-ablfusion gene encodes a novel tyrosine kinase with transforming activity. In this study, we have synthesized a multi-unit ribozyme that targets bcr-ab/ mRNA. In vitro ribozyme cleavage reacti...

Five multigenerational kindreds with familial hypertension were typed for human leukocyte antigen (HLA) and blood group antigens to investigate genetic factors that influence variability in blood pressure. Pedigree analysis revealed that children of matings in which both parents were hypertensive had a significantly greater risk of hypertension than children of matings in which one parent or ne...

One intradermal injection of incomplete Freund's adjuvant-oil induces a T cell-mediated inflammatory joint disease in DA rats. Susceptibility genes for oil-induced arthritis (OIA) are located both within and outside the major histocompatibility complex (MHC, Oia1). We have searched for disease-linked non-MHC loci in an F2 intercross between DA rats and MHC-identical but arthritis-resistant LEW....

Tryptic peptide sequences from the 22 kDa polypeptide of tomato LHCI were used to construct a probe for gene cloning. The two genes cloned, cab11 and cab12, encode proteins of 251 and 250 residues that are 88% identical in overall amino acid sequence and 93% identical in the deduced mature protein. Each gene is present in a single copy per haploid genome; cab11 on chromosome 3 and cab12 on chro...
