The Power behind BMC Atrium

Study of Optimal Area of Atrium for Daylight Utilization (Case Study: Administrative Building in Qazvin, Iran)

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...

Heart rate variability after radiofrequency ablation of epicardial ganglionated plexuses on the ovine left atrium

BACKGROUND Ganglionated plexuses (GP) are terminal parts of cardiac autonomous nervous system (ANS). Radiofrequency ablation (RFA) for atrial fibrillation (AF) possibly affects GP. Changes in heart rate variability (HRV) after RFA can reflect ANS modulation. METHODS Epicardial RFA of GP on the left atrium (LA) was performed under the general anesthesia in 15 mature Romanov sheep. HRV was used...

Relationship of Weight and Body Mass Index with Femur and Lumbar Vertebrae Bone Mineral Density and Content in Premenopausal Women

Purpose: Given that weight and body mass index (BMI) are considered as modifiable factors in osteoporosis, the present study aimed to examine the relationship of weight and BMI with bone mineral density (BMD) and bone mineral content (BMC) at the femur and lumbar vertebrae in perimenopausal women. Methods: In this descriptive-correlational study, we measured the bone density of the femur and...

Effects of two new dihydropyridine derivatives, mepudipine and dibudipine, on isolated human internal mammary artery and rat left atrium

  Among the present classes of calcium channel blockers, dihydropyridine derivatives are widely used in the therapy of hypertension, angina pectoris and the other cardiovascular diseases. Since the prototype of dihydropyridine derivatives, nifedipine, does not have the optimum pharmacokinetic and pharmacodynamic characteristics, several attempts have been made to synthesize other drugs in this ...
