Campylobacter is genetically highly diverse and undergoes frequent intraspecific recombination. Turkeys have been identified as an important reservoir for Campylobacter jejuni which is of public health significance. The assessment of the genetic diversity among Campylobacter population is critical for our understanding of the epidemiology of this bacterium. The genetic profiles were different a...
The study characterized the lactoferrin (Lf) mRNA gene in different goat breeds Philippines and determined its association with subclinical mastitis (SCM). involved collection of milk at second week lactation (n=75) blood samples (n=5) to obtain extracted RNA using cDNA amplify Lf through polymerase chain reaction. nucleotide amino acid sequences were used as reference evaluation phylogenetic r...
Although nitrification has been well studied in coniferous forests of Western North America, communities of NH(3)-oxidizing bacteria in these forests have not been characterized. Studies were conducted along meadow-to-forest transects at two sites (Lookout and Carpenter) in the H. J. Andrews Experimental Forest, located in the Cascade Mountains of Oregon. Soil samples taken at 10- or 20-m inter...
Aberrant DNA methylation patterns, including global hypomethylation, gene-specific hypermethylation/hypomethylation, and loss of imprinting (LOI), are common in acute myelogenous leukemia (AML) and other cancer tissues. We investigated for the first time whether such epigenetic changes are induced in healthy subjects by low-level exposure to benzene, a widespread pollutant associated with AML r...
BACKGROUND Dietary isoflavones are thought to be cardioprotective because of their structural similarity to estrogen. The reduction of concentrations of circulating inflammatory markers by estrogen may be one of the mechanisms by which premenopausal women are protected against cardiovascular disease. OBJECTIVE Our aim was to investigate the effects of isolated soy isoflavones on inflammatory ...
BACKGROUND Mycoplasmas are present worldwide in a large number of animal hosts. Due to their small genome and parasitic lifestyle, Mycoplasma spp. require complex isolation media. Nevertheless, already over 100 different species have been identified and characterized and their number increases as more hosts are sampled. We studied the applicability of amplified rDNA restriction analysis (ARDRA)...
Wider availability but lack of legal market trades has given feline meat a high potential for use as an adulterant in common meat and meat products. However, mixing of feline meat or its derivatives in food is a sensitive issue, since it is a taboo in most countries and prohibited in certain religions such as Islam and Judaism. Cat meat also has potential for contamination with of severe acute ...
In the present study further characterization of the amplified sequence of the citrate synthase gene of the spotted fever group Rickettsia isolated from Ixodes ricinus ticks in Sweden showed that it has 100% homology with the deposited sequence of the citrate synthase gene of Rickettsia helvetica. The restriction fragment length polymorphism (RFLP) pattern of an amplified 382-bp product of the ...
زمینه و هدف: هورمون کلسیتونین یکی از هورمون هایی است که میزان کلسیم بدن و استخوان سازی را تنظیم می کند. برای این منظور هورمون به رسپتور خود، یعنی کلسیتونین رسپتور با تمایل بالا متصل می شود. همچنین کلاژن یکی از پروتئین های اصلی تشکیل دهنده ی ماتریکس استخوان می باشد. مطالعات قبلی نشان داد که پلی مورفیسم های موجود دراین ژن ها با میزان تراکم استخوان در ارتباط می باشند، از اینرو در این مطالعه پلی مو...
