Atrium is a popular architectural feature utilized widely by building designers and owners to bring various benefits such as adequate daylight, circulation spaces and surfaces for landscape applications. But atrium problems in tropical climates such as excessive daylight, glare and high temperature, which lead to increase building energy demand, have been reported. Atrium has been used with var...

conclusions a right atrium myxoma in a patient with a history of multiple soft tissue tumors has been limited to only a few cases. this may suggest a genomic affinity or similarity; if so, those with multiple different type soft tissue masses should be screened for a heart mass before the mass becomes complicated. introduction heart secondary tumors are much more common than primary tumors. the...

decreased cardiac responsiveness to adrenergic stimulation has been observed in cholestatic liver disease, but the cause remains unclear. previous reports have suggested that nitric oxide overproduction might have a role in cholestasis-induced bradycardia via inhibition of l-type calcium channels. in the present study, the digoxin has been used to increase cardiac ca2+ transient in male sprague...

the first step in evaluating the visual performance and energy efficiency provided by daylight, requires an accurate estimation of the amount of daylight entering a building. the atrium concept allows the exploitation of daylight by bringing natural light into the center of the buildings, thus enhancing even a more distribution of daylight. daylight reception through an atrium is particularly b...

conclusions the authors emphasize on the rarity of this pathology among children, its clinical polymorphism, the necessity of a rapid diagnosis, and an appropriate treatment to avoid complications and recurrence of the tumor. introduction right atrial myxoma is a rare disease among children and its clinical presentation is not specific. case presentation we reported a four-year-old girl with ex...

background recently, assessment of the atrial motion and deformation indices obtained via doppler myocardial imaging (dmi) has been proposed as a new method of exploring the atrial function. objective our aim was to assess the right atrial (ra) regional function using myocardial velocities, strain, and strain rate imaging (sri) and compare it with the function of the inter-atrial septum (ias) a...

We herein describe a 34-year-old woman with a persistent left superior vena cava (PLSVC) impinging on the posterior wall of the left atrium, subdivided by a membrane at the distal part of the impingement. In this patient, a much dilated coronary sinus due to the PLSVC resulted in a membrane-like structure in the posterior wall of the left atrium with the appearance of the cor triatriatum in tra...
