When grasping an object, subjects tend to look at the contact positions of the digits (A. M. Brouwer, V. H. Franz, D. Kerzel, & K. R. Gegenfurtner, 2005; R. S. Johansson, G. Westling, A. Bäckström, & J. R. Flanagan, 2001). However, these contact positions are not always visible due to occlusion. Subjects might look at occluded parts to determine the location of the contact positions based on ex...

3 Pattern recognition involves building a mental model to interpret incoming inputs. 4 This incoming information is often incomplete and the mental model must 5 extrapolate to complete the patterns, a process that is constrained by the statistical 6 regularities in nature. Examples of pattern completion involve identification of 7 objects presented under unfavorable luminance or interpretation ...

Newborn infants were familiarized to a three-dimensional display consisting of a rod which moved behind a central occluder, so that , only the top and bottom of the rod were visible. The infants’ eyes were 38 cm from the rod and the occluder was 15 cm in front of the rod, a separation intended to ensure that the gap between the two was detected by the infants. On subsequent test trials the infa...

OBJECTIVE We wanted to evaluate the effectiveness of intraluminal irradiation with Holmium-166 ((166)Ho) for reducing the pseudointimal hyperplasia (PIH) in the transjugular intrahepatic portosystemic shunt (TIPS) tract in a swine model. MATERIALS AND METHODS TIPS was performed in 12 domestic pigs, after the creation of portal hypertension by intraportal injection of a mixture of N-butyl-2-cy...

Subjects and Methods. We analysed 5000 cerebrovascular ultrasound records. A total of 0.4% of the patients had common carotid artery occlusion (CCAO). Results. The mean age was 59.8 ± 14.2 years, and the male/female ratio was 2.33. The most frequent risk factors were hypertension, ischaemic heart disease, dyslipidemia, diabetes mellitus, and smoking. Right-sided and left-sided CCAO occurred in ...

Regional Cerebral Blood Flow Measured by the Gamma Camera After Direct Injection of Xe into the Distal Stump of the Occluded Middle Cerebral Artery • Regional cerebral blood flow (rCBF) was measured after intracarotid injection of Xe concurrently with measurements of local cerebral blood flow (LCBF) after injection of Xe directly into the distal stump of the occluded middle cerebral artery (MCA...

Acute pulmonary embolism causes redistribution of blood in the lung, which impairs ventilation/perfusion matching and gas exchange and can elevate pulmonary arterial pressure (PAP) by increasing pulmonary vascular resistance (PVR). An anatomically-based multi-scale model of the human pulmonary circulation was used to simulate pre- and post-occlusion flow, to study blood flow redistribution in t...

hypertension is a common complication of kidney transplantation with the prevalence of 80%. studies in adults have shown a high prevalence of hypertension (htn) in the first three months of transplantation while this rate is reduced to 50- 60% at the end of the first year. htn remains as a major risk factor for cardiovascular diseases, lower graft survival rates and poor function of transplante...

Background: Stent implantation has evolved as an important therapeutic strategy for aortic coarctation. Aim: This study aimed to present the experience of aortic coarctation stenting using the Cheatham-Platinum stent by an Adult Interventional Cardiology Team. Material and methods: The data of 11 patients (ages were between 15 to 58 years) who underwent aortic coarctation stent implantation bet...

Radiofrequency ablation (RFA) is commonly used as a treatment for small hepatocellular carcinoma (HCC). Although several complications such as intraperitoneal bleeding are often observed after RFA, hepatic arterioportal fistula (APF) is a less frequently occurring complication. In this study, we describe two cases of APF caused by RFA, which was successfully occluded by an interventional approa...
