Research ArticleOpen accessIn the abstractImproving Medical Imaging and Blood Flow Measurement by using a New Doppler Effect RelationshipFlorian Ion T. PetrescuThe Doppler Effect represents the frequency variation of the waves, received by an observer which is drawing (coming), respectively it’s removing (going), from a wave spring (source). One proposes to study the Doppler Effect for the light waves, generally for the electromagnetic waves. Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842 in … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 14 Oct 2015 · 12,852 accessesView PDFCite
Research ArticleOpen accessIn the abstractDiagnosis of Cardiovascular Diseases with Bayesian ClassifiersAlaa Elsayad, Mahmoud FakhrCardiovascular disease or atherosclerosis is any disease affecting the cardiovascular system. They include coronary heart disease, raised blood pressure, cerebrovascular disease, peripheral artery disease, rheumatic heart disease, congenital heart disease and heart failure. They are treated by cardiologists, thoracic surgeons, vascular surgeons, neurologists and interventional radiologists.

Research ArticleOpen accessIn the abstractEffect of Exercise Prior or After Ischemia on the Density of Neurons and Astrocytes in the Brain of RatsLaila Cristina Moreira Damázio, Raphael Teixeira Rocha Melo, Maira de Castro Lima et al.The aim of this study was to analyse the density of astrocytes and neurons in the motor areas of the cortex, striatum and hippocampus of rats that performed exercise before or after cerebral ischemia. A total of 36 Wistar rats were separated into two groups: One that was subjected to Middle Cerebral Artery Occlusion (MCAO) and the other that underwent … …Neuroscience International, Vol. 5, Issue 2 · 14 Jan 2015 · 7,345 accessesView PDFCite
Research ArticleOpen accessIn the abstractCALCITONIN GENE-RELATED PEPTIDE IN SERUM AFTER SPONTANEOUS SUBARACHNOID HEMORRHAGEKarl-Michael Schebesch, Elisabeth Bruendl Andreas Hochreiter, Judith Scheitzach et al.Endogenous Calcitonin Gene-Related Peptide (CGRP) stored in perivascular nerve fibers around the cerebral arteries mediates vasodilation and regulates cerebral blood flow under physiological conditions. Increased levels of CGRP have been continually reported in patients with migraine, but the role of CGRP in the pathophysiology of Subarachnoid Hemorrhage (SAH) has not yet been sufficiently evaluated. Over 10 days, serum was prospectively … …Neuroscience International, Vol. 5, Issue 1 · 28 Jun 2014 · 7,588 accessesView PDFCite
Research ArticleOpen accessIn the abstractCAROTID PLAQUE CLASSIFICATION USING CONTOURLET FEATURES AND SUPPORT VECTOR MACHINESM. Thangavel, M. Chandrasekaran, M. MadheswaranThe aim of this study is to propose a suitable and reliable system for better diagnosis and treatment of carotid diseases. In this study, Computer Aided Diagnosis (CAD) system has been proposed for classifying carotid artery plaques using Contourlet features. Carotid images have been acquired for 124 subjects with symptoms (Amaurosis Fugax, Stroke or Transient Ischemic Attack) and 133 subjects … …Journal of Computer Science, Vol. 10, Issue 9 · 15 Apr 2014 · 6,776 accessesView PDFCite
Research ArticleOpen accessIn the abstractAUTOMATIC RETINAL VESSEL TORTUOSITY MEASUREMENTNidhal Khdhair El Abbadi, Enas Hamood Al SaadiRetinal vascular vessels have the role to indicate the retinal diseases and for systematic diseases when there are any abnormalities in retinal vascular pattern. A characteristic of the vascular pattern that is appreciated by clinicians is vascular tortuosity, i.e., how curved or kinked a blood vessel, either vein or artery, appears along its course. In this study we suggest a … …Journal of Computer Science, Vol. 9, Issue 11 · 21 Sep 2013 · 7,210 accessesView PDFCite

Therefore, the searching for an acceptable cheap and safe neuroprotective agent is in a great demand. Based on the neuroprotective and cognitive enhancing effects in alcohol neurotoxicity of mulberry … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 1 Sep 2012 · 6,967 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnti-Cardiolipin Antibody in Acute Myocardial InfarctionAbdolreza Sotoodeh Jahromi, Mohammad Shojaie, Samira Dana, Abdoulhossain MadaniProblem statement: Myocardial infarction is the combined result of environmental and personal factors. Data concerning the relation between anti-Phospholipid (aPL) antibodies and myocardial infarction in subjects without evidence of overt autoimmune disease are conflicting. Anticardiolipin antibody is detected in various diseases like rheumatoid arthritis, systemic lupus erythematosus and anti-phospholipid antibody syndrome. The study of Anticardiolipin antibody in Acute Myocardial Infarction … …American Journal of Immunology, Vol. 6, Issue 1 · 31 Mar 2010 · 7,827 accessesView PDFCite
