Our findings suggest that brachial-ankle pulse wave velocity is a significant predictive factor for cardiovascular disease in the general Japanese population and that information on brachial-ankle pulse wave velocity substantially improves cardiovascular risk assessment beyond that achieved by a model based on potential risk factors in general practice.
Noninvasive cSBP calculated with rSBP2 accorded well with aSBP measured by the invasive method. Vasodilator medication and four of five diseases did not affect this relation.
Aim: Peripheral artery disease (PAD), defined as a decreased ankle brachial index (ABI), is a risk factor for cardiovascular disease; however, few studies have assessed the relationship between a low ABI and cardiovascular risks in Asian populations. We herein examined the relationship between the ABI and the development of cardiovascular disease in a Japanese community. Methods: A total of 2,954 community-dwelling Japanese individuals without prior cardiovascular disease ≥ 40 years of age were followed up for an average of 7.1 years. The subjects' ABIs were categorized into the three groups: low (≤ 0.90), borderline (0.91-0.99) and normal (1.00-1.40). We estimated the relationship between the ABI and cardiovascular risk using a Cox proportional hazards model.
This review describes a new enzymatic method for in vitro glycogen synthesis and its structure and properties. In this method, short-chain amylose is used as the substrate for branching enzymes (BE, EC 2.4.1.18). Although a kidney bean BE and Bacillus cereus BE could not synthesize high-molecular weight glucan, BEs from 6 other bacterial sources produced enzymatically synthesized glycogen (ESG). The BE from Aquifex aeolicus was the most suitable for the production of glycogen with a weight-average molecular weight (Mw) of 3,000-30,000 k. The molecular weight of the ESG is controllable by changing the concentration of the substrate amylose. Furthermore, the addition of amylomaltase (AM, EC 2.4.1.25) significantly enhanced the efficiency of this process, and the yield of ESG reached approximately 65%. Typical preparations of ESG obtained by this method were subjected to structural analyses. The average chain length, interior chain length, and exterior chain length of the ESGs were 8.2-11.6, 2.0-3.3, and 4.2-7.6, respectively. Transmission electron microscopy and intrinsic viscosity measurement showed that the ESG molecules formed spherical particles. Unlike starch, the ESGs were barely degraded by pullulanase. Solutions of ESG were opalescent (milky-white and slightly bluish), and gave a reddishbrown color on the addition of iodine. These analyses revealed that ESG shares similar molecular shapes and solution properties with natural-source glycogen. Moreover, ESG had macrophage-stimulating activity and its activity depends on the molecular weight of ESG. We successfully achieved large scale production of ESG. ESG could lead to new industrial applications, such as in the food, chemical, and pharmaceutical fields.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
