Molecular activities can be predicted by Quantitative Structure Activity Relationship (QSAR). Because of the high cost of experiments, the number of drug molecules with known activity is much less than that of unknown, to predict molecular activities utilising unlabelled instances will be an interesting issue. Here, Semi-Supervised Learning (SSL) is introduced and a SSL method, Co-Training is i...
Background: Coronary Artery Disease (CAD) is one of the major causes of mortality in most countries. Electrocardiography (ECG) and myocardial perfusion imaging (MPI) are non-invasive disgnostic tests for CAD. Finding a relationship between abnormal findings in the baseline ECG and MPI findings can be helpful in better diagnosis of CAD. Materials and Methods: The present study examined ECG of pa...
A quantitative structure activity relationship analysis was applied to a library of 51 benzylacetamide derivatives with anticonvulsant activity. The molecular structures of 51 compounds were optimized with the Semiempirical Method PM6 (Parametric Method-6) included in the MOPAC2009 software. The optimized structures of all the examined compounds were represented by 1497 DRAGON-type descriptors....
مقدمه: رزیستین، یک هورمون مترشحه از بافت چربی است که نقش مهمی را در تنظیم هموستاز انرژی و متابولیسم ایفا میکند. هدف از این تحقیق بررسی تاثیر تمرین هوازی منظم بر بیان ژن رزیستین لنفوسیت زنان جوان تمرین کرده بود. روش تحقیق: 20 زن جوان بسکتبالیست (عضو لیگ استان) شهر مشهد که سابقه تمرینی 4 سال تمرین مداوم داشتند بطور تصادفی انتخاب و به دو گروه کنترل و تجربی تقسیم شدند. گروه تجربی به مدت 8 هفته و...
rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
