As Jan van Dalen opened in a previous issue [1], ‘It is every Editor’s dream that articles in ‘‘their’’ journal serve a wide population of interested readers.’ But how do we succeed in producing such articles? What is of crucial importance is that an article provides answers to the questions ‘What is new?’ and ‘What is in there for me?’, and that it does not comprise too many elements that dist...
از آغاز عصر فضا و شروع سفرهای فضائی مدت زیادی نمی گذرد . با پرتاب نخستین قمر ساخت بشر به فضا دوران واقعی سفرهای فضائی آغاز گردید ، و پس از موفقیت برنامه های فضائی آمریکا در پیاده نمودن نخستین انسان بر سطح ماه به نقطه اوج خود رسید سپس گام های بعدی برای فتح سیارات نزدیک برداشته شد و سفاین بدون سرنشین متعددی عازم مطالعه منظومه شمسی شدند. بی شک سفر به نقاط دیگر که در فواصل دورتری از زمین قرار دارند...
Objective(s): Cognitive deficit is a common problem in epilepsy. A major concern emergent from the use of antiepileptic drugs includes their side effects on learning and memory. Herbal medicine is considered a complementary and alternative therapy in epilepsy. Apigenin is a safe flavone with antioxidant properties. However, there is little information about the benefic...
Patients with Alzheimer's disease have cognitive deficits, impaired long-term potentiation and learning and memory. A progressive reduction in cholinergic neurons in some areas of the brain such as cortex and hippocampus is related to the deficits in memory and cognitive function in Alzheimer’s disease (AD). In the current project a new series of phthalimide derivatives were synthesized. Phthal...

To investigate brain substrates of spatial memory, neuronal expression of c-Fos protein was studied. Two groups of rats were trained in two spatial memory tasks in the Morris water maze, where the rats have to apply a reference memory rule or a working memory rule. In addition to the experimental groups, two control groups were used to study c-fos activation not specific to the memory processes...
زمینه و هدف : شکنج دندانهای (Dentate gyrus) بخشی از تشکیلات هیپوکامپی است که در رابطه با حافظه و یادگیری دخالت دارد. آستروسیتها از جمله سلولهای نوروگلیا در بافت عصبی هستند که نقش مهمی را در فعالیتهای نورونها از جمله رهاسازی نوروترانسمیترها و تولید سیناپس بهعهده دارند. این مطالعه به منظور تعیین اثر آموزشهای فضائی بر تعداد سلولهای آستروسیت شکنج دندانهای موش صحرائی انجام شد. روش بررسی: ا...
Reference Counting is the memory management technique of most widespread use today. Very often applications handle objects that are either permanent or get tenured. This paper uses this information to make cyclic reference counting more efficient.
