a case of soft tissue defect of dorsal hand due to crush injury in a 37-year-old female is reported here. the reconstructive surgery was performed for the hand soft-tissue defect. among different flaps used in the surgery, the regional flap such as radial forearm flap can be done. but usually it is not accepted by patient because of cosmetic appearance. therefore, random pattern abdominal flap ...

Caseous calcification of the mitral annulus is a rare form of periannular calcification with a mass-like appearance, that has to be in the differential of the cardiologist and radiologist. It classically looks like a round or semilunar hyperdense mass with an even denser peripheral rim, located in the posterior mitral annulus and having in general no clinical significance.

Two-dimensional echocardiography of a patient revealed overriding of the large aortic trunk which bifurcated above the semilunar valve, suggesting persistent truncus arterious. This diagnosis was confirmed by cardiac catheterization and angiocardiography. Surgery and autopsy also confirmed the accuracy of the two dimensional echocardiographic findings. Two-dimensional echocardiography is thus v...

BACKGROUND Gingival recession may result in aesthetically unfavourable effects, difficulty in plaque control, increased susceptibility to root caries, and dentin hypersensitivity. OBJECTIVE The aim of this study was to compare the use of modified semilunar techniques with connective tissue and subepithelial connective tissue grafts (Langer) for denuded root surface coverage. METHODS In this...

Sympatric assemblages of congeners with incomplete reproductive barriers offer the opportunity to study the roles that ecological and non-ecological factors play in reproductive isolation. While interspecific asynchrony in gamete release and gametic incompatibility are known prezygotic barriers to hybridization, the role of mating system variation has been emphasized in plants. Reproductive iso...

BACKGROUND Outflow tract ventricular tachycardia originating above the semilunar valves has been reported in a small number of studies. Discrete potentials in the great arteries (above the semilunar valves) have been rarely described in patients undergoing electrophysiology evaluation and radiofrequency ablation for ventricular arrhythmias. The mechanisms of these discrete potentials in the gre...

Mapping and ablating arrhythmias in the great arteries were rarely in the realm of consideration to treat tachyarrhythmias for the first 2 decades of invasive electrophysiology,1 More recently, it has become clear that a variety of arrhythmias including ventricular tachycardia, atrial tachycardia, and accessory pathways can be ablated successfully in the great arteries and the cusps of the semi...

AIMS The mesenchymal cushions lining the early embryonic heart undergo complex remodelling to form the membranous ventricular septum as well as the atrioventricular and semilunar valves in later life. Disruption of this process underlies the most common congenital heart defects. Here, we identified a novel role for Slit-Robo signalling in the development of the murine membranous ventricular sep...

Receptive field properties of cells deep in the posterior bank of lunate sulcus and on the annectant gyrus (V3) were studied in the awake, fixating monkey. Properties of these cells were compared with those of a population of cells recorded in V2. Receptive fields of cells in V3 were larger than fields of V2 cells at comparable eccentricities. Cells were classified according to their sensitivit...
