The intent of this study was to determine whether endurance exercise training regulates increases in metabolic enzymes, which parallel modulations of myogenin and MyoD in skeletal muscle of rats. Adult Sprague-Dawley rats were endurance trained (TR) 5 days weekly for 8 wk on a motorized treadmill. They were killed 48 h after their last bout of exercise. Sedentary control (Con) rats were killed ...

BACKGROUND Tuberculosis is one of the most prominent health problems in the world, causing 1.75 million deaths each year. Rapid clinical diagnosis is important in patients who have co-morbidities such as Human Immunodeficiency Virus (HIV) infection. Direct microscopy has low sensitivity and culture takes 3 to 6 weeks 123. Therefore, new tools for TB diagnosis are necessary, especially in health...

Approximately 2.0 x 10 cDNA clones of an Schistosoma mansoni lambda gt11 cDNA library were screened in duplicate with serum from infected mice corresponding to distinct phases of infection. A cDNA clone (7/1) was isolated and recognized only by seven week serum. The clone was subcloned in pGEX-2T and Western-blot studies showed a specific antigenic expression confirming that only serum from the...

A cloned 2-kb EcoRI fragment (fragment f) from a 34-kb plasmid of Lactobacillus helveticus CNRZ 1094 was shown by dot blot to specifically hybridize to total DNAs of 75 L. helveticus strains. No hybridization was found with L. acidophilus, L. crispatus, L. delbrueckii subsp. bulgaricus, L. delbrueckii subsp. lactis, L. gasseri, or L. intestinalis strains. When Southern blots of EcoRI digests of...

We describe a simple approach for detecting beta-thalassemia mutations in geographic areas such as southern China where multiple mutations are known to occur. Segments of the beta-globin gene were amplified in vitro by using the polymerase chain reaction. Dot blot hybridization of the amplified DNA with oligonucleotide probes corresponding to the six mutations found in southern China could dire...

Polymerase chain reaction (PCR) technique was applied to detect BHV-1 in bovine semen inoculated with BHV-1. The technique was found to be 10(6) times more sensitive than a non-isotopic dot-blot hybridization method in detecting viral genomic DNA. Of the three primer pairs used, the one chosen from glycoprotein gC appeared to be most sensitive as it could detect up to 0.01 TCID50 of BHV-1 in th...

We characterized sequences of a novel SSS139 RsaI satellite DNA family in Drosophila gouveai and Drosophila seriema, two members of the Drosophila buzzatii cluster (D. repleta group). The sequences were AT-rich (69%) with a monomer unit length of about 139 bp and contained two direct subrepeats of 14 bp and 16 bp, suggesting that it might have originated by the duplication of smaller sequences....

The ability to recover sufficient amounts of deoxyribonucleic acid (DNA) from various biological evidentiary samples for individualization purposes is discussed. The chemistry and stability of DNA under various conditions is reviewed. The recovery of nondegraded DNA bears directly on the ability to successfully analyze such samples by restriction fragment length polymorphism analysis, as well a...

Contaminated vaccine is one unexpected and potential origin of virus infection. In order to investigate the most likely cause of disease in a broiler breeder company of Shandong Province, all 17 batches of live-virus vaccines used in the affected flocks and 478 tissue samples were tested by dot-blot hybridization, nested PCR, and IFA. The results suggested the outbreak of disease was most proba...
