a molecular survey was performed for identification theileria spp in sheep and ticks during from 2010-2011 in fasa and kazeroun areas, fars province, iran. a total of 100 sheep from different flocks were clinically examined and blood samples with ixodid ticks collected. the prepared blood smears from capillary vein of ear were stained with giemsa methods and examined by using light microscope. ...
background toxoplasmosis is a widespread disease in humans and many other species of warm-blooded animals. among livestock animals, sheep and goat are more widely infected by toxoplasma gondii. this parasite is a major cause of abortion, with significant economic losses for sheep and goat breeders. objectives the polymerase chain reaction (pcr) method was employed to detect of the t. gondii dna...
Different microbial identification methods have shown that the microbial community profiles in endodontic infections are diverse and assorted. The aim of this study was to evaluate the frequency of selected endodontic pathogens in the pulp chambers (PCs) and root canals (RCs) of infected primary teeth using PCR methods. Paired PC and RC samples were collected from 15 subjects and analyzed by PC...
A simple and rapid method for the detection of Tilletia horrida, the causal agent of rice kernel smut, in rice seeds is developed based on specific polymerase chain reaction (PCR). To design the specific primers for the detection of T. horrida, partial sequences of internal transcribed spacer (ITS) DNA region of T. horrida, T. controversa, T. walkeri, T. ehrhartae, T. indica and T. caries were ...
We report on syntheses and electron transport properties of polycrystalline samples of diborides (AB2) with different transition metals atoms (A=Zr,Nb,Ta). The temperature dependence of resistivity, ρ(T ), and ac susceptibility of these samples reveal superconducting transition of ZrB2 with Tc = 5.5 K, while NbB2 and TaB2 have been observed nonsuperconducting up to 0.37 K. Hc2 (T) is linear in ...
The expression of cytoplasmic CD3 (CyCD3) was analyzed in 45 leukemias, five thymus cell samples. five peripheral blood (PB) samples, and ten cell lines. All T cell acute lymphoblastic leukemias (T-ALL) that did not express surface membrane CD3 (SmCD3) appeared to express CyCD3. Furthermore, the majority of SmCD3 T-ALL also expressed CyCD3. Analogous results were obtained with thymus cell sampl...
Toxoplasma gondii is a worldwide prevalent parasite, affecting a wide range of mammals and human beings. Little information is available about the distribution of genetic diversity of T. gondii infection in minks (Neovison vison). This study was conducted to estimate the prevalence and genetic characterization of T. gondii isolates from minks in China. A total of 418 minks brain tissue samples ...
در این پایان نامه به معرفی مدولهای t-توسعه یافته و مدولهای t-بئر است که تعمیم یافته ای از مدولهای توسعه یافته می باشند. و همچنین مفاهیم t-توسعه یافته و -tبئر برای r-مدولها رابترتیب به fi-t-توسعه یافته و fi-t-بئر تعمیم می دهیم. ما نشان می دهیم که تصویرهمریخت یک مدول t-توسعه یافته و یک جمعوند مستقیم از یک مدول t-بئر ویژگی هایشان را به ارث می برند.این نشان دهنده ی این است که مدول m، t-توسعه یافته ...
Mature T cells express either CD8 or CD4, defining two physiologically distinct populations of T cells. CD8+ T cells, or killer T-cells, and CD4+ T cells, or helper T cells, effect different aspects of T cell mediated adaptive immunity. Currently, determining the ratio of CD4+ to CD8+ T cells requires flow cytometry or immunohistochemistry. The genomic T cell receptor locus is rearranged during...
Background: The American foulbrood disease (AFB), caused by Paenibacillus larvae subsp. larvae, is one of the main plagues affecting honey bee (Apis mellifera L.) colonies, and it has a high negative impact on beekeepers worldwide. OBJECTIVES: The aim of this research was to describe the evidence of Paenibacillus larvae larvae contamination of honey bee colonies, in the East Azerbaijan Province...
