Of 279 patients with transposition of the great arteries, 14(5%) had narrowing of the aorta, including local coarctation (6), isthmus hypoplasia (6), isthmus atresia (1), and kinking of the aorta (1). There were six deaths in 10 surgically treated patients; in addition four patients died before operation. Two of the four survivors had a subpulmonary malalignment ventricular septal defect with a...

The only effective intervention to slow onset and progression of glaucomatous blindness is to lower intraocular pressure (IOP). Among other modulators, adenosine receptors (ARs) exert complex regulation of IOP. Agonists of A(3)ARs in the ciliary epithelium activate Cl(-) channels, favoring increased formation of aqueous humor and elevated IOP. In contrast, stimulating A(1)ARs in the trabecular ...

BACKGROUND Recent clinical studies have shown that recanalization rates are lower in stent-assisted coil embolization than in coiling alone in the treatment of cerebral aneurysms. OBJECTIVE This study aimed to assess and compare the hemodynamic effect of stent struts and straightening of vessels by stent placement on reducing flow velocity in sidewall aneurysms, with the goal of reducing reca...

Inflow reducing surgical procedures have had a sordid history mostly characterized by poor outcomes and substantial complications. Difficulties were mainly due to the lack of direct visualization of the target tissue and by poor control of the destructive force. Collateral damage to healthy tissue from external cyclodestruction leads to significant inflammation and complications. The transvitre...

I A small plastic bell connected to a reservoir suspended on a strain gauge and to a pressure recorder was fixed over a fistula in the scleral wall of Schlemm's canal. The anterior chamber was similarly connected to a reservoir and a pressure transducer. In a majority of vervet eyes an increase of the pressure in the bell over the intraocular pressure caused a bulk inflow into the canal through...

The objective of this study was to analyze the density and distribution of the bivalve Anomalocardia brasiliana in beaches in the estuarine region of the semiarid in Rio Grande do Norte State, Barra and Pernambuquinho (04°56.978'S and 37°08.961'W and 04°56.792'S and 37°09.375'W, respectively). Samples were collected monthly during 37 months using five transects (300 m long and 400 m apart) laid...

BACKGROUND AND PURPOSE Inflow jet characteristics may be related to aneurysmal bleb formation and rupture. We investigated the visualization threshold on the basis of the flow velocity in the parent artery to classify the inflow jet patterns observed on 4D flow MR imaging. MATERIALS AND METHODS Fifty-seven unruptured aneurysms (24 bifurcation and 33 sidewall aneurysms) were subjected to 4D fl...

furrow irrigation is the most common type of surface irrigation. determine the advance and recession time in the field is required the accurate measurement and this can be costly and time consuming. winsrfr model is used for simulation furrow irrigation by zero inertia and kinematic wave engines. using this model, advance time, reaction time, infiltration depth, runoff depth and application eff...

Methods We compared SSFP four chamber view images (20 phases per cycle protocol) between 11 surgically-confirmed CP patients and 11 controls. We deconvoluted the mechanics of the septal bounce and correlated it with periods of the cardiac cycle. To demonstrate that the septal bounce is caused by the interaction between the tricuspid inflow and septum we constructed a parameter called the septal...
