In angiography, simultaneous exposure in two planes with fast film changer may produce unsatisfactory results. This is especially so where it concerns detailed studies of narrow vessels and also in the ease of heavier individuals. The reduction in image quality is due to secondary radiation. This may be eliminated by using alternate exposures in two planes. The method is suitable is vessel investigations in very dense objects and also in cases where a high picture frequency with synchronous pictures in two planes is not diagnostically necessary (coronary angiography under heart arrest, aortic aeurysms and so forth).

    Abstract: Chronic heart failure is a complex catabolic state that carries a devastating prognosis. The transition from stable disease to cardiac cachexia is not well understood. Mechanisms that maintain the wasting process involve neurohormones and pro-inflammatory cytokines, which contribute to...

    Abstract: Objective: In chronic heart failure (CHF) the myocardial expression of the inflammatory cytokine tumor necrosis factor alpha (TNF-a), which is thought to contribute to myocardial remodeling, was found to be increased. However, it is unknown whether the E3-ubiquitin ligases MAFbx and...
