in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
در این پایان نامه، ناپایداری لیزر الکترون آزاد دوجریانی را در حضور ویگلر الکترومغناطیس و میدان مغناطیسی محوری، در رژیم رامان بررسی کردیم. رابطهی پاشندگی کلی، شامل امواج الکتروستاتیک و الکترومغناطیس جفت شده ای که در طول باریکه های الکترونی، در حضور میدان های ویگلر و محوری، منتشر میشوند را به دست آوردیم. همچنین رابطهی پاشندگی موج الکترومغناطیس راستگرد را در غیاب امواج بار-فضا و الکترومغناطیس چ...

Distinct classes of neurons are generated at defined positions in the ventral neural tube in response to a gradient of Sonic Hedgehog (Shh) activity. A set of homeodomain transcription factors expressed by neural progenitors act as intermediaries in Shh-dependent neural patterning. These homeodomain factors fall into two classes: class I proteins are repressed by Shh and class II proteins requi...
Background: The aim of preliminary study was determined development process status of T-cell population lymphocytes in Ukrainian children after 22 years from Chernobyl accident for next feasibility study. Material and Method: 150 participants aged 6 to 16 years are included in three groups: Group I (n=65), 30 to 60 km from center accident at zone 3th, Group II (n=65) 60 to 90 km from s...

In spite of the common concept that all types of cholelithiasis have fairly similar clinical signs and symptoms, we noticed quite a difference in their clinical presentation and prognosis between the two groups of patients that had multiple stones (group I) or single stone (group II) cholelithiasis. To varfiy this clinical assumption, we reviewed 125 patients which underwent cholecystectomy wit...
