It is the matter of fact that not only our reading audience has significantly expanded recently, but more important, we note an increasing number of physicians among our readers who successfully apply theory in practice.
In the suggested here linear theory of hydrodynamic instability of the Hagen - Poiseuille flow it is counted the possibility of quasi periodic longitudinal variations, when there is no separation of the longitudinal and radial variables in the description of the disturbances field.
The article presents the results of space experiment “Pneumocard”. The investigation involved all 25 Russian members of the ISS crew. The total of 226 sessions were made including 130 aboard the ISS, 50 prior to launch and 46 on return from mission.
The Sonocard experiment purpose was a noninvasive physiological signal recording from sleeping humans. In 2007-2012 the experiment was made by 22 Russian members of 17 missions to the International space station. Of the overall 302 experimental sessions 47 were performed pre, 215 in and 40 after flight.
Congenital paroxysmal atrial fibrillation in infants is a rare occurrence requiring a high index of suspicion. The majority have a pre-excitation syndrome which may be concealed. It may be associated with specific structural congenital cardiac lesions. This index case had only paroxysmal atrial tachyarrhythmia with no predisposing condition that subsided spontaneously and is the first case documented in an Afro-Caribbean infant.
A shortcoming common to all existing designs of mechanical cardiac valve prostheses is an increased trombogenicity caused, among other factors, by the lack of hydrodynamic compatibility between the luminal part of the prosthesis and the patterned blood flow. The aim of the study is to design and test our new mechanical aortic valve prosthesis to exclude life-long anticoagulation treatment.
Hypertrophic cardiomyopathy (HCM) is the commonest inherited cardio-myopathy. Prevalence 1/500 individuals. The disease has variable expressivity and penetrance, which leads to a diverse phenotypical expression. The aim of this review paper is to shed light on management of HCM.
