چکیده انگیزه دلیل اصلی رفتارهای ما است. به نظر می رسد انگیزه جزء جدایی ناپذیر فرایند یادگیری باشد. ارزش ذاتی موفقیت تمایل به پیشرفت را در یادگیرنده ایجاد میکند. به عبارت ساده این تمایل انگیزه پیشرفت نامیده میشود. انگیزه پیشرفت را میتوان در احساس یادگیرنده هنگام چالش با درس های مدرسه، لذت انجام فعالیت درسی، یا حس کشف پاسخ مشاهده کرد.حتی ممکن است انگیزه پیشرفت را در تلاش یادگیرنده برای جلب تایید...
Studies of the kinetic mechanism of orotate phosphoribosyltransferase from yeast.
Kinetic analysis of the reaction catalyzed by a homogeneous preparation of orotate phosphoribosyltransferase from yeast has revealed that the reaction may proceed through the use of a Bi Bi Ping Pong kinetic mechanism. This interpretation is based on initial rate measurements and product inhibition studies of both the forward phosphoribosyl transfer and the reverse pyrophosphorolysis reactions ...
متن کاملExpression of thymidylate synthase and orotate phosphoribosyltransferase in thymic carcinoma
Thymic carcinoma is a rare thymic epithelial tumor in which chemotherapy for advanced disease has not yet been established. Thymidylate synthase (TS) and orotate phosphoribosyltransferase (OPRT) protein expression levels in thymic carcinoma were evaluated as possible indicators of the anticancer activity of 5-fluorouracil (5-FU) drugs using immunohistochemistry (IHC). A total of 24 samples of t...
متن کاملCholine acetyltransferase (ChAT) immunoreactivity in paraffin sections of normal and diseased intestines.
There is increasing interest in localizing nerves in the intestine, especially specific populations of nerves. At present, the usual histochemical marker for cholinergic nerves in tissue sections is acetylcholinesterase activity. However, such techniques are applicable only to frozen sections and have uncertain specificity. Choline acetyltransferase (ChAT) is also present in cholinergic nerves,...
