To understand the molecular properties of matrilin-3, a newly discovered member of the novel extracellular matrix protein family, we cloned a MAT-3 cDNA from developing chicken sterna. Real time quantitative reverse-transcription polymerase chain reaction indicates that MAT-3 mRNA is mainly expressed in the proliferation zone of a growth plate. It is also expressed in the maturation zone, overl...

Rather than landfilling, composting the organic fraction of municipal solid wastes recycles the waste as a safe and nutrient enriched soil amendment, reduces emissions of greenhouse gases and generates less leachate. The objective of this project was to investigate the composting effectiveness of three bulking agents, namely chopped wheat (Triticum) straw, chopped mature hay consisting of 80% t...

Toxoplasma gondii infects all species of warm-blooded animals, including humans, and domestic cats and other felidae are its definitive hosts. The aim of the present survey was to compare serological and molecular tests in accurate diagnosis of T. gondii infection among stray cats in Ahvaz, Iran. A total of 100 cats were examined for the detection of serum antibodies against T. gondii (chronic ...

background: neospora caninum , an obligate intracellular protozoan parasite, is recognized as a major cause of abortion in cattle, while limited information is presently available on the seropreva­lence of neospora antibodies in horses' worldwide .the aim of the present study was to de­termine serologic prevalence of neospora infection in horses in iran. methods: sera from 150 horses from mashh...

leptospirosis in cattle is a worldwide problem associated with abortion, agalactia, still birth and infertility resulting in major economic losses to dairy industry. there is lack of data regarding seroprevalence of bovine leptospirosis in eastern india. so, with the aim to investigate the prevalence of the disease in odisha and west bengal state of eastern india, a total of 350 cattle serum sa...

In most fungal ascomycetes, mating is controlled by a single locus (MAT). Fungi requiring a partner to mate are heterothallic (self-sterile); those not requiring a partner are homothallic (self-fertile). Structural analyses of MAT sequences from homothallic and heterothallic Cochliobolus species support the hypothesis that heterothallism is ancestral. Homothallic species carry both MAT genes in...

We identified and purified a new DNA polymerase (DNA polymerase IV), which is similar to mammalian DNA polymerase beta, from Saccharomyces cerevisiae and suggested that it is encoded by YCR14C (POLX) on chromosome III. Here, we provided a direct evidence that the purified DNA polymerase IV is indeed encoded by POLX. Strains harboring a pol4 deletion mutation exhibit neither mitotic growth defec...

In wild-type diploid cells of Saccharomyces cerevisiae, an HO endonuclease-induced double-strand break (DSB) at the MAT locus can be efficiently repaired by gene conversion using the homologous chromosome sequences. Repair of the broken chromosome was nearly eliminated in rad52delta diploids; 99% lost the broken chromosome. However, in rad51delta diploids, the broken chromosomes were repaired a...

EDITOR—In approximately 10% of patients with SilverRussell syndrome, preand postnatal growth retardation with relative macrocephaly, triangular facies, and asymmetry is associated with maternal uniparental disomy of chromosome 7 (UPD(7)mat). The purpose of this report is to present a novel assay to diagnose UPD(7)mat by analysing the methylation status of PEG1/MEST, the only known imprinted gen...
