Abstract: Cerebrovascular disease risk including stroke is projected as the second most frequent cause for death/disability by year 2020. Preventive measures tominimize stroke related hippocampal cognitive impairmentin high risk group gains least attention among health-care professionals. Several studies establish the critical importance of essential dietary components choline and Docosahexaenoic acid [DHA] as neuronal membrane phospholipid precursors that maintain cognitive states in health and in neurological disorders. There are no studies exploring the synergetic neuro-protective potential of choline and DHA in attenuating hippocampal neural deficits in stroke-risk group. The present study explores synergetic neuro-protective potential of choline and DHA supplemented to Wistar rats prior to hypo-perfusion ischemic brain injury. 10 month-old male Wistar rats were subdivided into 4 groups [n=8 /group]-Normal control group [NC], Bilateral common carotid artery occlusion group [BCCAO], Sham BCCA

Abstract: Solids of revolution have applications in various fields such as manufacturing (casting, machining), computer aided designing etc., wherein axis-symmetric solids are generated by revolution of curves. Most often the curves corresponding to these solids are irregularly shaped. Thus, regular integration cannot be applied to obtain definite volume of such solids. Hence, given a set of function values (radii), an approximation of volume of the solid can be made. The approximation introduced here (frustum approximation), divides the solid into a number of frustums of cones, instead of following the conventional approach of dividing the solid into cylinders. The summation of all the individual volumes of the frustums, gives the approximate volume of the total solid. The study also compares and analyzes the frustum approximation with existing methods of approximating integrals. The results indicate that for all sub-intervals of solids that are ‘concave’ in nature, the frustum approach generat
