We have tested the steady-state predictions of the hypothesis that coarctation hypertension, if renin-mediated via total-renal underperfusion, will be characterized by a persistently abnormal renin/bodyfluid-volume relationship. In six inbred Labrador dogs with neonatally-induced thoracic aortic coarctation and in seven littermate controls, serial measurements of forelimb BP, plasma renin activ...

BACKGROUND All international guidelines recommend perioperative antibiotic prophylaxis (PAB) should be routinely administered to patients undergoing cardiac surgery. However, the duration of PAB is heterogeneous and controversial. METHODS Between 01.01.2011 and 31.12.2011, 1096 consecutive cardiac surgery patients were assigned to one of two groups receiving PAB with a second-generation cepha...

Gupta SC, Varian KD, Bal NC, Abraham JL, Periasamy M, Janssen PM. Pulmonary artery banding alters the expression of Ca transport proteins in the right atrium in rabbits. Am J Physiol Heart Circ Physiol 296: H1933–H1939, 2009. First published April 17, 2009; doi:10.1152/ajpheart.00026.2009.—Following pulmonary artery banding (PAB), the contractile function of right ventricle diminishes over time...

Atrial fibrillation (AF) is the most common type of arrhythmia encountered clinically. AF risk factors include hypertension, diabetes, obesity, or heart failure. Right disease (RHD) has also been described among associated with an atrial inflammatory profile leading to AF. The mechanisms relating RHD, inflammation, and are poorly described. main objective project characterize proarrhythmogenic ...

As we know breast cancer is the second death reason in Iran. One step of treatment process is radiotherapy, which needs careful consideration of contouring and therapeutic techniques Lung, thyroid, spinal cord, trachea and humerus are sensitive organs in breast cancer radiation therapy.  The most clinical studies recommended two ways for delivering 95 percent of dose to supraclavicular and ...

Ilex spinigera (Aquifoliaceae) plant is an evergreen tree or shrub with thick glossy dark green leaves and red fruits. This plant has medicinal properties and has been used traditionally in northern Iran for malaria treatment. The aim of this work is to evaluate the antioxidative activities and the inhibitory effect of I. spinigera on the oxidation of DNA. We have found no reports about the pop...

BACKGROUND Neo-aortic root dilation (ARD) and neo-aortic regurgitation (AR) may be progressive after arterial switch operation (ASO) for d-loop transposition of the great arteries (dTGA). We sought to identify predictors of ARD and AR after ASO. METHODS AND RESULTS 335 patients were identified who underwent ASO for dTGA with intact ventricular septum or ventricular septal defect (VSD), includ...

BACKGROUND Ankle injuries are the most common high school basketball injury. Little is known regarding the utilization of ankle injury prevention strategies in high school settings. OBJECTIVE To determine high school basketball coaches' utilization of ankle injury prevention strategies, including prophylactic ankle bracing (PAB) or an ankle injury prevention exercise program (AIEPP). STUDY ...

The support system is the most important part of foundation pit engineering, which mainly determines safety engineering. Based on characteristics Changsha international financial center, original pile-anchor-beam (PAB) improved into a new form system, pile-anchor-ribbed-beam (PARB) system. This study establishes numerical simulation model to calculate surface settlement and deformation retainin...
