Molecular techniques have been introduced for malaria diagnosis because they offer greater sensitivity and specificity than microscopic examinations. Therefore, DNA isolation methods have been developed for easy preparation and cost effectiveness. The present study described a simple protocol for Plasmodium DNA isolation from EDTA-whole blood. This study demonstrated that after heating infected...

secreted cytokines of th1 (t-helper)/th2 cells play an important role in the pathogenesis of many diseases. th1 cells secrete predominantly ifn-γ and il-2 which regulate cell-mediated immunity against intracellular pathogens and tumors. in this study, expression of ifn-γ was studied using semiquantitative rt-pcr. in brief, lymphocytes of a healthy donor were stimulated with pha (1μg/106 cell/ml...

AIMS Evaluation of iQ-Check PCR Salmonella for Salmonella detection in artificially and naturally contaminated food and environmental field samples. METHODS AND RESULTS Artificially contaminated samples (poultry meat and ground red meat) subjected to cold- and freeze-stress, and 120 naturally contaminated samples (swabs and meat) were tested for Salmonella using the diagnostic semi-solid Salm...

An association between human papillomavirus (HPV) and cervical neoplasia has been widely reported and HPV DNA is commonly detected in cervical carcinoma tissues. However, estimates of the prevalence of HPV infection differs among various detection methods. Seventy cases of cervical carcinoma were screened for HPV 16 infection by Southern blot hybridisation (SBH) and nested polymerase chain reac...

abstract- desert truffles are hypogeous ascomyceteous ectomycorrhizal fungi, occurring in arid and semi-arid ecosystems. a pcr-based method was developed for the identification of 3 major desert truffles of iran: terfezia claveryi, tirmania pinoyi and tirmania nivea based on internal transcribed spacers of rdna. two specific pcr primers were designed for t. claveryi, 4 for t. pinoyi, and 2 for ...

The human intestine has a vast variety of microorganisms, and their balance is dependent on several factors. Antibiotics affect microfloral balance and allow naturally opportunistic organisms to multiply. Azithromycin is the most widely used macrolide antibiotic, active against a wide number of pathogens including Pseudomonas aeruginosa and Staphylococcus aureus. It is currently used in the tre...

Neospora caninum, an apicomplexan protozoan, is regarded as a major cause of abortion and stillbirth in cattle in countries world-wide. The ability to detection N.caninum in tissue samples can be a useful detection diagnostic tool for use in the study of the pathogenicity, immunoprophylaxis, and treatment of Neospora infection. However, molecular biology is one of the most sensitive tools for d...

Introduction The purpose of this work is to examine the applicability of dynamic P MRS to a single exercising muscle using gradient based localisation in a 7T whole body scanner. The increased sensitivity obtainable with ultra high field is attractive for P MRS with its intrinsically low SNR. Dynamic studies of metabolism are often conducted using non-localised acquisitions using surface coils....
