تغییرات ضربان قلب (heart rate variability) در طی التهاب سیستمیک کاهش پیدا می کند، امّا مکانیسم آن ناشناخته است. این مطالعه به منظور بررسی اثرات محیطی و مرکزی اینترلوکین6 به عنوان یکی از سایتوکاین های تولید شده در شرایط التهاب سیستمیک بر روی تغییرات ضربان قلب انجام شد. بدین منظور مطالعات مولکولی، in vitro و in vivo بر روی موش های balb/c نر طراحی و انجام شدند. با مطالعات مولکولی نشان داده شد که mr...

one of the most effective ways to propagate lilium is by using tissue culture techniques, preferably through bulblet production. in addition to the surviving percentage of lilium bulbs after transplantation, the small size of in vitro bulblets compared to commercial bulbs and bulblets‟ dormancy are the most important constraints to commercializing lilium micropropagation. different concentratio...

Maguey, Agave salmiana, is an important plant for the "pulque" beverage and functional food industries; however, it has several constraints for elite and homogeneous plant production. In this study, a micropropagation process was established to generate in vitro plants. The effect of the method on metabolite content and antioxidant (AOX) activity in regenerated plants was evaluated. Young germi...

Abstract Ninebark is a very popular ornamental shrub. Micropropagation an efficient method for mass production of uniform plant material. This study was designed to develop and optimize conditions at all phases ninebark micropropagation. For the multiplication stage, Murashige Skoog (MS) medium full concentration pH 5.8 chosen as basal medium. Sorbitol proved more effective carbohydrate source ...

In vitro flowering and effective micropropagation protocol were studied in Swertia chirayita, an important medicinal plant using axillary bud explants. The Murashige and Skoog's medium (MS) supplemented with benzyl amino purine (BAP) 1.0 mg L(-1) and adenine sulfate 70.0 mg L(-1) was found optimum for production of multiple shoots. In the present study, incubation of flowering cultures on BAP s...

The Amplification Fragment Length Polymorphism (AFLP) technique was employed to study genetic variations which can be induced in vines by the stress occurring during different aspects of viticulture (in vitro cultivation, in vitro thermotherapy and virus infection). Analysis of AFLP banding patterns, generated by using 15 primer combinations, pointed to negligible genetic variation among plants...
