Previous clinical attempts to correct genetic deficiencies such as hemophilia or Gaucher disease by transplantation of allogeneic spleen were associated with aggressive graft versus host disease, mediated by mature T cells derived from the donor spleen. We show that a fetal pig spleen harvested at the embryonic day 42 stage, before the appearance of T cells, exhibited optimal growth potential u...
Supernates of neuraminidase and galactose oxidase (NAGO)-treated lymphocytes induce blastogenesis in nonproliferating cells harvested 7--14 d after treatment with mitogen or alloantigen and in cells incubated with mitogen for 7--14 d but not in freshly isolated peripheral blood lymphocytes9 Virtually all the growth factor is produced by NAGO-treated cells during the first 24 h of incubation, an...

امروزه، در بیشتر اراضی سرعت فرسایش خاک بیش از سرعت تشکیل خاک است. در نتیجه باعث تهی شدن منابع خاک و کاهش توانایی حاصلخیزی خاک می شود. در ایران استان گلستان به علت موقعیت جغرافیایی و اقلیمی آن و تخریب بالای منابع آن و همچنین به علت اینکه سطح وسیعی از اراضی از لس تشکیل شده دارای میزان فرسایش خاک بالایی می باشد. یکی از راه های تخمین میزان فرسایش و رسوب و بررسی میزان تلفات مواد غذایی خاک استفاده از...
Waterfowl frequently acquire high-energy agricultural seeds in harvested and unharvested croplands during migration and winter. Estimates of agricultural seed biomass in harvested and unharvested corn, soybean, and grain sorghum fields do not exist or are outdated for the southeastern United States. Therefore, we estimated seed biomass in 105 harvested and 59 unharvested corn, soybean, and grai...
Due to yield increase, some farmers in Iran plant sugarbeet in 50-cm row spacing instead of conventional 60-cm row spacing. Low row spacings force farmers to harvest three consecutive rows instead of two alternate rows. This would increase the amount of draft requirement to pull the lifter through the soil. In order to use common medium tractors for pulling the three-unit sugarbeet lifter and p...
