 There is a dearth of data on the prevalence of osteoporosis in Vietnam. This study was designed to preliminarily estimate the incidence of osteoporosis in the Vietnamese population. The study was designed as a population-based, epidemiological investigation. Men and women aged 18 years or above, who were residents of the City of Hanoi (Vietnam) and(More)
D ysorexia nervosa (DN) includes two types of eating disorder: anorexia nervosa (AN) and bulimia nervosa (BN). AN is a syndrome characterised by changes in eating habits, distortions of body shape, and a refusal to maintain even minimally normal body weight. BN is a syndrome encompassing repeated episodes of binge eating, followed by inappropriate(More)
The relationship between coronary artery disease (CAD) and polymorphisms of genes encoding angiotensinogen (AGT) and angiotensin converting enzyme (ACE) was analyzed in Japanese subjects. One hundred and four patients with CAD and 170 healthy subjects were enrolled in the study. CAD was defined as having a luminal diameter stenosis > or =50% in at least one(More)
In this paper linear hyperbolic cocycles are classiied by the relation of topological conjugacy. Roughly speaking, two linear cocycles are conjugate if there exists a homeomorphism which maps their tra-jectories into each other. The problem of classiication of discrete-time deterministic hyperbolic dynamical systems was investigated by Rob-bin (1972). He(More)
In this paper structural stability of discrete-time linear random dynam-ical systems is studied. A random dynamical system is called structurally stable with respect to a random norm if it is topologically conjugate to any random dynamical system which is suuciently close to it in this norm. We prove that a discrete-time linear random dynamical system is(More)
Polymorphisms of angiotensin-converting enzyme (ACE) and angiotensinogen (AGT) genes have been reported to be associated with myocardial infarction and coronary artery disease, both of which are closely related to atherosclerosis and insulin resistance. In this study, we investigated the association between ACE and AGT genotypes and insulin sensitivity in a(More)
In this paper we study topological properties of continuous-time linear hyperbolic cocycles. Roughly speaking, two cocycles are called conjugate if there exists a random homeomorphism mapping their orbits into each other; a cocycle is called structurally stable if it is conjugate to every cocycle from a neighborhood of itself. We prove that any linear(More)
