Background This study was designed to develop a new co-culture system, assess the effect of luteinizing hormone (LH) using sequential media to promote development and increase the quality of 2-cell murine embryos through the 8-16 cell stage to morula and blastocyst stages. MaterialsAndMethods Monolayers for co-culture were prepared from ovine oviduct epithelial cells (OOEC) in DMEM/F12 medium a...
یکی از مهم ترین مشکلات سیستم های ofdm عدم توانایی این سیستم ها در حذف سیگنال تداخل در باند فرکانسی سیگنال مطلوب می باشد. برای حذف این تداخلات از روش های شکل دهی پرتو استفاده می شود. دو روش مرسوم شکل دهی پرتو، روش pre-fft (شکل دهی پرتو در حوزه زمان) و روش post-fft (شکل دهی پرتو در حوزه فرکانس) می باشند. برای به روزرسانی وزن ها در هر دو روش راه حل های مختلفی پیشنهاد شده است که می توان همه آن ها ر...
BACKGROUND The quality of microbiological diagnostic procedures depends on pre-analytic conditions. We compared the results of 16S rRNA gene PCR and sequencing from automatically incubated blood culture materials from tropical Ghana with the results of cultural growth after automated incubation. METHODS Real-time 16S rRNA gene PCR and subsequent sequencing were applied to 1500 retained blood ...

 Methods: A pre-experimental, one-group pretest-posttest test design was used. The sample consisted (n = 38) 174) staff nurses; included theoretical components, group work, individual assi...
Streptomyces carzinostaticus produces the antitumor protein, NCS, and at the same time a related protein which antagonizes the antimicrobial effect of NCS. This has been designated pre-neocarzinostatin (pre-NCS). The physicochemical properties of pre-NCS are very close to those of NCS, except for a difference in isoelectric point. Production of pre-NCS in the culture filtrate precedes productio...
This comparative cross-cultural study explores the prevalence of preoccupation with weight and eating patterns among female university students in two distinct cultural contexts, Cyprus and Lebanon. Data was collected by means of self-administered questionnaires to 200 students from each culture. To gather the data for this study, the Dutch Eating Behavior Scale was used for the assessment of e...
One way to develop intercultural sensitivity in learners is through the inclusion of intercultural training in ELT and teacher training courses. This study aimed at enhancing the intercultural sensitivity of EFL pre-service teachers through interactive culture-focused speaking tasks. Therefore, a task-based syllabus was designed based on the principles of constructivism and intercultural themes...
PURPOSE OF THE STUDY Culture change models are intended to improve the quality of life for nursing home residents, but the impact of these models on quality of care is unknown. We evaluated the impact of the implementation of nursing home culture change on the quality of care, as measured by staffing, health-related survey deficiencies, and Minimum Data Set (MDS) quality indicators. DESIGN AN...
