Background & Aim: Problem-based learning, as a relatively new educational approach, has found a high status in higher-educational institutions. The present study aimed to investigate the effect of problem-based learning on nursing students' communication skills. Methods: This is a quasi-experimental study, in which a total of 78 fourth-year nursing students were recruited and allocated into two...
Toxoplasmosis is a major zoonotic disease of warm-blooded animals caused by Toxoplasma gondii. Cats are the only definitive host and they excrete environmentally resistant T. gondii oocysts in their faeces. Coproscopy was used to detect oocysts of enteric coccidians and then Copro-PCR was employed to test specifically for T. gondii in 470 cat samples. The prevalence of T. gondii oocysts was 2.3...
the aim of this study was to investigate the effect of morphology instruction through semantic mapping on vocabulary learning of iranian intermediate efl learners. to do so, 50 out of 70 students were se-lected from one english language institute by administrating a pet test. then, they were assigned into two groups randomly as experimental and control groups. a pretest (teacher made) was admin...

This study was conducted for detection of Toxoplasma gondii genotypes in rats (Rattus rattus) in Riyadh region, Saudi Arabia. PCR test on T. gondii B1 gene was conducted on ELISA IgM positive samples for confirmation of the infection. However, genetic analysis of th...
Multiplex allele-specific fluorescent PCR for haplotyping the IVS8 (TG)m(T)n locus in the CFTR gene.
BACKGROUND Precise genotyping of the intron 8 poly(TG) and poly(T) tracts of the cystic fibrosis transmembrane conductance regulator (CFTR) gene is of clinical relevance in CFTR pathology. The (TG)(m) locus influences the penetrance of the (T)(5) allele, which may be associated with male infertility by congenital bilateral absence of the vas deferens (CBAVD) or other CFTR-related disorders (CFT...
