promoter polymorphism of cytokine genes may lead to inter-individual differences in cytokine levels, therefore, polymorphisms may associate with susceptibility to infectious diseases. in this study, we investigated a possible association between interleukin-10 (il-10) -1082a⁄g (rs1800896) and interferon (ifn)-gamma +874t/a (rs2430561) promoter polymorphisms and tuberculosis (tb) in the azeri po...
The CYP2A6 gene, which codes the enzyme, has known to have ahigh polymorphism. This polymorphism could decrease, increase, or eliminate enzyme activity. CYP2A6*4 , an inactive allele, decreased One of enzyme-specific substrates is nicotine. allele decrease nicotine metabolism that causes high levels in blood. In addition, it caused increasing Low-Density Lipoprotein Cholesterol (LDL-C) by expan...
Rapid resistance detection is necessary for the adaptive management of acaricide-resistant populations of Tetranychus urticae. Detection of phenotypic and genotypic resistance was conducted by employing residual contact vial bioassay (RCV) and quantitative sequencing (QS) methods, respectively. RCV was useful for detecting the acaricide resistance levels of T. urticae, particularly for on-site ...
Anthelmintic resistance in parasitic nematodes of livestock is a chronic problem in many parts of the world. Benzimidazoles are effective, broad-spectrum anthelmintics that bind to and selectively depolymerise microtubules. Resistance to the benzimidazoles, however, developed quickly and is caused by genetic changes in genes encoding beta-tubulins, subunits of microtubules. In Haemonchus contor...
Short tandem repeats are used as an effective method to trace DNA markers in genotyping. Using a standardized kit, we tested 11 microsatellite markers recommended by the International Society for Animal Genetics (ISAG) in a sample of 495 Sicilian cattle. The aim of this study was to investigate the allele frequencies in the Sicilian cattle population to provide a reference database and at the s...
A recently duplicated gene can either fix a null allele (becoming a pseudogene) or fix an (advantageous) allele giving a slightly different function, starting it on the road to evolving a new function. Here we examine the relative probabilities of these two events under a simple model. Null alleles are assumed to be neutral; linkage effects are ignored, as are unequal crossing over and gene con...
background: pulmonary tuberculosis (ptb) has recently become a major problem in developed countries especially in immune compromised hiv infected individuals. cytokines, their genes and receptors have been implicated in the protective immunity, pathophysiology and development of tuberculosis. material & methods: in the present study the genotype frequencies of a number of polymorphic genes co...
Rice stripe virus (RSV) causes one of the most serious viral diseases of rice (Oryza sativa L.), but the molecular basis of RSV resistance has remained elusive. Here we show that the resistant allele of rice STV11 (STV11-R) encodes a sulfotransferase (OsSOT1) catalysing the conversion of salicylic acid (SA) into sulphonated SA (SSA), whereas the gene product encoded by the susceptible allele ST...
This paper starts from the ISO distinction of three types of evaluation procedures – internal, external and in use – and proposes to match these types to the three types of human language technology (HLT) systems: analysis, generation, and interactive. The paper explains why internal evaluation is not suitable to measure the qualities of HLT systems, and shows that reference-based external eval...
In 1 , a framework of core-stateless fair queueing CSFQ , which does not require per flow management or operation at core routers, was proposed. It is able to provide high quality of services while maintaining a high level of robustness, simplicity and scalability. In this framework, one key element is the calculation of the fair share rate, which is briefly reviewed in the next section. The ac...
