Allostery provides a critical control over enzyme activity, biasing the catalytic site between inactive and active states. We found that the Ciona intestinalis voltage-sensing phosphatase (Ci-VSP), which modifies phosphoinositide signaling lipids (PIPs), has not one but two sequential active states with distinct substrate specificities, whose occupancy is allosterically controlled by sequential...

Kidney transplantation from older and marginal donors is effective to confront organ shortage. However, limitations after of kidneys very kidney remain unclear. We compared patient graft outcome, achieved allograft function quality life renal transplantations Very Senior Donors (VSD, defined as aged 70 years older) with (SD, 60-70 years) Regular (RD, younger than 60 years) in Switzerland. evalu...

Acquired intracardiac left-to-right shunts are rare occurrences. Chest trauma and myocardial infection are well-known causes of acquired ventricular septal defect (VSD). There have been several case reports describing left ventricle to right atrium shunt after infective endocarditis (IE). We present here a patient found to have an acquired VSD secondary to IE of the aortic and tricuspid valves ...

Figure 1 Transesophageal echocardiogram (TEE). Two-dimensional TEE without (A) and with color (B) showing subarterial VSD (red arrow) and hypertrophy of the basal septum (white arrow) below the VSD. The defect was w5 mm in size and hemodynamically benign as the pulmonary to systematic blood flow ratio (Qp/Qs) was calculated from cardiac catheterization data to be 1.6:1. The ascending aorta was ...

The case of a 20 years old male, diagnosed as supracristal ventricular septal defect (VSD) for last 6 years is being presented. He came in emergency department with decompensated congestive cardiac failure. After initial stabilization, he underwent transthoracic echocardiogram which showed large supracristal VSD, severely prolapsing right coronary cusp, severe aortic regurgitation and severe pu...

Background/Aim: Ventricular septal defect (VSD) is the most common congenital heart anomaly that in many cases closes spontaneously. The spontaneous closure (SC) rate of VSD varies widely between studies. aim this study was to identify clinical and echocardiographic factors influencing SC isolated first year life among a group patients presented at Paediatric Clinic. Methods: Prospective perfor...

OBJECTIVES We sought to review our experience with surgical ventricular septal defect (VSD) closure in adults. BACKGROUND Outcome data of VSD closure in adults on which to base recommendations are limited. Guidelines recommend closure of adult VSD for a Q(p)/Q(s) ratio > or =2, left ventricular volume overload, or endocarditis. METHODS We retrospectively reviewed 46 patients (mean age 33.6 ...

Ventricular septal defect (VSD) with prolapse of the right coronary cusp and aortic regurgitation can be managed surgically with the anatomical correction technique. However when the VSD is located underneath the non coronary cusp surgical management differs due to anatomical constraints and secondary pathological changes seen in the non coronary cusp. It is therefore important that the locatio...
