Arterial stiffness is an important factor for cardiovascular performance and a predictor of cardiovascular risk. We evaluated the effects of both acute and long-term aerobic exercise on arterial stiffness in community-dwelling healthy elderly subjects. In addition, we evaluated the relationship between the effects of longterm exercise and those of acute exercise. The study subjects were participants in the Shimanami Health Promoting Program study (J-SHIPP), which was designed to investigate factors relating to cardiovascular disease, dementia, and death (67 ± 6 years). They performed mild-to-moderate aerobic exercise lasting for 30 min twice a week for 6 months. Arterial stiffness was assessed before and after the first 30-min acute exercise (n =99) and long-term 6-month aerobic training (n =40). The radial arterial augmentation index (AI) obtained from the radial pulse waveform by the tonometry method was used as a parameter of arterial stiff-

Background:The uncertainty in the 29 P(p, γ) 30 S reaction rate over 0.1 ≤ T ≤ 1.3 GK was previously determined to span ∼4 orders of magnitude due to the uncertain location of two previously unobserved 3 + and 2 + resonances in the E x = 4.7 -4.8 MeV region in 30 S. Therefore, the abundances of silicon isotopes synthesized in novae, which are relevant for the identification of presolar grains of putative nova origin, were uncertain by a factor of 3.
