Nghiên cứu phẫu, soi bột, đánh giá hoạt tính ức chế acetylcholinesterase chống oxy hoá lớn. bằng phương pháp kính hiển vi. Hoạt enzyme Ellman hóa thực hiện trên hình loại bỏ gốc tự do 2,2-diphenyl-1-picrylhydrazyl (DPPH). Đây l...
Bioactive compounds from plants play an important role in slowing many neurodegenerative diseases, such as Alzheimer’s disease, by inhibiting cholinesterase enzymes. Studies have shown that oxidative stress is associated with the development of disease. In traditional medicine Bosnia and Herzegovina, Teucrium montanum used to treat numerous diseases. The chemical composition biological activity...
background and objective: changes of the enzyme acetylcholinesterase are involved in pathogenesis of different nervous disorders including alzheimer’s disease. this research work was conducted to evaluate the inhibitory effect of pistacia lentiscus ethanolic extract on acetylcholinesterase activity. materials and methods: activity of the enzyme acetylcholinesterase (ache) was measured by ellman...
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...

INTRODUCTION AND OBJECTIVE Acetylcholinesterase (AChE) and cholinergic receptors play an important role in the immune system, including lymphocyte-induced angiogenesis. However, their exact role is not fully understood. The presented work tests the influence of isopropyl methylphosphonofluoridate (IMPF), an irreversible inhibitor of AChE, on selected immune parameters associated with angiogenes...
