A brain is considered to be asymmetrical if the two hemispheres are different from each other, structurally, and/or functionally. The most well established brain asymmetry is related to language, in which the specialized left hemisphere is markedly expanded in most people, especially in Broca’s speech area, the planum temporale (Toga and Thompson, 2003). Brain asymmetry is believed to be evolut...

purpose: to evaluate the effectiveness of pars plana vitrectomy and posterior hyaloid stripping in decreasing macular thickness and improving vision in diabetic macular edema.          methods: this prospective interventional case series includes 30 eyes of 25 diabetic patients with diabetic macular edema with macular thickness exceeding 170 microns and thickened posterior hyaloid. bcva and mac...

AIM To identify factors that may influence ridge alterations occurring at the buccal aspect of the extraction site following immediate implant placement. MATERIAL AND METHODS In 93 subjects, single-tooth implants were placed immediately into extraction sockets in the maxilla (tooth locations 15-25). A series of measurements describing the extraction site were made immediately after implant in...

OBJECTIVES We sought to better understand the effects of aging and gender on left ventricular (LV) structure and function. BACKGROUND Cardiovascular disease in older persons is associated with increased mortality and morbidity. The influence of gender on age-related cardiac changes is incompletely characterized. METHODS We studied 34 senescent, male and female, normotensive Fischer rats wit...

OBJECTIVE To compare the accuracy of positioning of the femoral tunnel in reconstructing the anterior cruciate ligament by means of 2 techniques: tibial tunnel and anteromedial portal. METHOD Femoral tunnels were drilled in 20 knees from human cadavers by means of arthroscopy. Group I had the femoral tunnel drilled via a trans-tibial tunnel, and Group II via the anteromedial portal. Four vari...

Clinical, hemodynamic, electrocardiographic (ECG), echocardiographic, left ventricular (LV), and coronary angiographic (CA) findings are reported in a case with apical hypertrophy (AH), a form of hypertrophic nonobstructive cardiomyopathy (HNCM). The most striking symptom was chest pain and the most conspicuous electrocardiographic finding consisted of giant negative T waves, reaching an amplit...

BACKGROUND Reports have shown that normotensive offspring of hypertensive parents (OHP) are at increased risk of developing systemic hypertension (SH) and adverse cardiovascular events later in life. The pathological antecedents of this are thought to be alterations in the structure and function of left ventricle. Therefore, the present study aimed at determining left ventricular mass and geome...

We studied nine freshmen and 14 senior oarsmen undergraduates during seven months of training and compared them with 17 age and sex-matched sedentary control subjects in order to assess the influence of heavy physical exercise on cardiac dimensions and maximal oxygen uptake. Standard M-mode echocardiographic techniques were used. At the start of the season senior oarsmen had a greater left vent...

Regional nonuniformity is a feature of both diseased and normal left ventricles (LV). With the use of magnetic resonance (MR) myocardial tagging, we performed three-dimensional strain analysis on 87 healthy adults in local cardiac and fiber coordinate systems (radial, circumferential, longitudinal, and fiber strains) to characterize normal nonuniformities and to test the validity of wall thicke...

The objective of this study was to evaluate and compare the effects Twin Block Forsus on Posterior Airway Passage (PAP) pharyngeal wall Thickness (PPWT) in treatment Class II division 1 malocclusion. This a 2-arm parallel, randomized controlled trial. A total 24 malocclusion patients indicated for with functional appliances were equally divided among (3M Unitek Corp, Monrovia, Calif) groups. Sk...
