In micropropagation of Anthurium the most important and sensitive stage, is callus induction from explant. This experiment was conducted in a completely randomized design with factorial arrangement in 4 replications in Sari Agriculture Sciences and Natural Resources University (SANRU) in 2010. The cultivar used in this study is Fire and leaf segments with and without main nervure, were used as ...
This study was conducted to evaluate the response of 18 rice (Oryza sativa L.) genotypes to callus induction and plant regeneration from immature embryo culture, using three media (MS, LS and N6). To evaluate callus induction rate, the following criteria were used: callus diameter, callus fresh weight and callus dry weight. Percentage of callus water content was also measured. After transferrin...
ماتریکس استخوان دمینراله شده (demineralized bone matrix) مثالی از مواد القاء کننده ی استخوان سازی است که توانایی القاء تمایز سلول های مزانشیمی را به سمت سلول های استخوانی دارد. اصطلاح"induction" مربوط به عمل برخی فاکتورهای رشد است که آبشاری از وقایع را از یک سلول چند توانی به سمت یک سلول استخوانی بالغ و سپس تشکیل بافت استخوانی به پیش می برد. هدف از این مطالعه ارزیابی خصوصیات استخوان سازی صفحه ر...
role of labor induction has increased in the last decade due to the early detection of fetal jeopardy. although very useful, oxytocin alone is not always successful for induction of labor. in a randomized clinical trial we compared vaginal dinoprostone plus oxytocin with oxytocin alone for induction of labor in 91 pregnant women at 40 weeks or greater gestation with bishop scores ≤ 4. fort...

Introduction: In order to study the alterations of beta 1 and 2 integrins mRNA level in rat lumbar spinal cord following the induction of chronic pain and its effect on the development of tolerance to morphine analgesia, we examined the level of expression of these genes in the presence of chronic pain, which is an inhibitor of morphine tolerance. We used induction of chronic pain alone and ...
Recent studies have revealed that the nuclear factor of activated T-cells (NFAT) is a transcription factor that is highly expressed in aggressive cancer cells and tissues, and mediates invasion through the transcriptional induction of pro-invasion and pro-migration genes. However, the mechanisms through which nuclear factor of activated T-cells, cytoplasmic 1 (NFATc1), in particular, translocat...
In the structure of direct vector control of an induction motor, there are three main sections that have important role in improvement of the induction motor drive operation. This three sections, including: 1- the estimation block of the feedback signals, 2- the block of the required PWM pulses generation for the inverter unit, and 3- control blocks (usually PI) for generating the require...
