We have implemented field models and performed a detailed numerical dosimetry inside our extremely-low-frequency electromagnetic bioreactor which has been successfully used in in vitro Biotechnology and Tissue Engineering researches. The numerical dosimetry permitted to map the magnetic induction field (maximum module equal to about 3.3 mT) and to discuss its biological effects in terms of indu...

سلول های بنیادی جنینی موشی ابزاری ارزشمند برای انجام مطالعات تمایز سلولی در شرایط in vitro هستند. تمایز سلولی فرایندی جدایی ناپذیر از رشد و نمو موجودات پرسلولی است. در این مطالعه نقش مسیر آپوپتوتیک میتوکندریایی و تغییرات سطح انرژی سلول در فرایند تمایز سلول های بنیادی موشی به کاردیومایوسیت و آپوپتوز بررسی شده است.

The use of a diabetic blood glucose meter for radiochromic film dosimetry in blood irradiation using x-ray beams on a medical linear accelerator has been investigated. The glucose meter provides optical density analysis in the visible and infrared region using a reflectance measurement technique. By comparing the 'blood sugar' level output with standard calibration gafchromic films a calibratio...
