The current study was conducted to identify the quantitative trait locus (QTL) for the body weight at age 1, 7, 14, 21 and 28 days and daily gain at age 0-1, 1-2, 2-3 and 3-4 weeks, slighter carcass weight and tonic immobility in Japanese quail. Two divergently lines of wild and white Japanese quail which maintained in the Animal Science Research Center of the Shahid Bahonar University of Kerma...

conclusions this study revealed allele frequency of some strs on chromosome 12 and 16 for the first time in iran, and indicated differences between subjects with metabolic syndrome and subjects in the control group. results there was no significant deviation in allelic frequencies from hardy-weinberg equilibrium for all the studied markers except for d12s1632 and d12s329. the long alleles in d1...

Previous chromosome information for the lower numbers 2n=14, 16, 18, and 20 in Asian Begonia are restricted to nine species two sections Diploclinium Platycentrum. Here we report first counts of four as well reconfirmed sect. We found 2n=12 B. cathcartii, lowest number known genus. The with reported is increased 13 Additionally, provide karyotypes seven Based on present results previous reports...

The objective of the present study was to detect quantitative trait loci for economically important traits in a family from a Bos indicus x Bos taurus sire. A Brahman x Hereford sire was used to develop a half-sib family (n = 547). The sire was mated to Bos taurus cows. Traits analyzed were birth (kg) and weaning weights (kg); hot carcass weight (kg); marbling score; longissimus area (cm2); USD...

BACKGROUND The vestibular apparatus of the vertebrate inner ear uses three fluid-filled semicircular canals to sense angular acceleration of the head. Malformation of these canals disrupts the sense of balance and frequently causes circling behavior in mice. The Epistatic circler (Ecl) is a complex mutant derived from wildtype SWR/J and C57L/J mice. Ecl circling has been shown to result from th...

Uniparental disomy (UPD) is the inheritance of both homologues of a chromosome from one parent. For most of the autosomes, there is no definitive clinical consequence of this abnormal inheritance. However, UPDs of chromosomes 6, 7, 11, 14, and 15 are associated with abnormal phenotypes owing to overexpression or underexpression of imprinted genes on those chromosomes. 2 Maternal UPD(14) (matUPD...

Cytogenetic abnormalities involving chromosome 14 band q32 are consistently observed in human T-cell tumors. Patients with ataxia-telangiectasia (AT) are especially prone to development of these tumors, which frequently carry either inversion inv(14)(q11;q32) or translocation t(14;14) (q11;q32) chromosomes. We have previously shown that the cytogenetic breakpoints of one t(14;14)(q11;q32) chrom...

Translocations involving chromosomes 8 and 14 in Burkitt's lymphoma (BL) often involve the switch mu (Smu) region on chromosome 14, which contains multiple repeats. This has enabled us to use the polymerase chain reaction (PCR) to detect breakpoints that involve this region on chromosome 14 and the c-myc gene on chromosome 8. Using pairs of flanking primers, each pair including one annealing to...

Three cloned mouse-human lines (B1-29, E2-42, and A2-31) secreting human immunoglobulin (Ig) were obtained from a fusion between the mouse myeloma line NS-1 and human tonsillar lymphocytes stimulated in vitro with pokeweed mitogen. One line, B1-29, has continued to secrete human IgG for a period of 2 yr in culture. This line was recloned three times to give a panel of secreting and nonsecreting...

Linkage analysis studies have indicated that the chromosome band 14q24.3 harbours a major gene for familial early-onset Alzheimer's disease (AD). Recently we localized the chromosome 14 AD gene (AD3) in the 6.4 cM interval between the markers D14S289 and D14S61. We mapped the gene encoding dihydrolipoyl succinyltransferase (DLST), the E2k component of human alpha-ketoglutarate dehydrogenase com...
