    Abstract: Khat is a natural stimulant from the Catha Edulis plant and is cultivated in the Republic of Yemen and certain areas of East Africa. Khat produces a modest degree of euphoria and slight hypomania. It results in insomnia and appears to improve the users' alertness and concentration. The main objective of this study was to determine ultrasound findin... Show More

    Abstract: Background: Demonstration of blood flow direction inside cardiac chambers can provide valuable information in normal subjects and pathologic cardiac processes. In our center we have already created a software able to generate the left ventricle (LV) model, the most important chamber of the heart. Method: The fundamental quantity that describes the ...

    Abstract: Background: How can mathematics help us to understand the mechanism of the cardiac motion? The best known approach is to take a mathematical model of the fibered structure, insert it into a more-or-less complex model of cardiac architecture, and then study the resulting fibers of activation that propagate through the myocardium. In our paper, we ha... Show More

    Abstract: Background: Successful mitral valve repair and replacement are dependent upon a full understanding of normal and abnormal mitral valve anatomy and function. The functional components of the mitral valve include: the left atrial wall, the annulus, the leaflets, the chordae tendineae, the papillary muscles, segments of the left ventricular myocardium...

    Abstract: Pulmonary arteriovenous fistulas (PAVFs) are rare vascular malformations (PAVMs) of the lung that could lead to severe hypoxiemia due to right-to-left intrapulmonary shunts. They may occur as isolated entities or associated with Osler-Rendu-Weber syndrome or hereditary haemorrhagic telangiectasia (HHT). We study 3 patients with Rendu-Osler-Weber di... Show More

    Abstract: Background: Necrotizing enterocolitis is the most common sever gastrointestinal emergency that affects premature newborns. It is often has a rapid onset with few signs that can be used to predict its occurrence. Its rapid onset and progression to morbidity and mortality initiates the researchers for seeking early diagnostic tools helping in detecti... Show More
