The Antioxidative Components from Alpinia nutans PUMID/DOI:DOI: 10.1076/phbi.41.1.7.14703 Pharm. Biol., 2003, 41(1):7-9. The methylene chloride extract of Alpinia nutans was investigated for its antioxidant constituents. 5,6-Dehydrokawain (1),flavokawin-B (2),l,7-diphenyl-5-hydroxy-6-hepten-3-one (5-Hydroxy-1,7-diphenyl-6-hepten-3-one,3),(-)-pinocembrin (4) and a mixture of stigmasterol and (3-sitosterol were isolated. The antioxidant activity was measured on isolates 1-4 using ferric thiocyanate (FTC) and diphenylpicrylhydrazyl (DPPH) free radical scavenging techniques.

Abstract

A new species of mastodon from the Pleistocene of western North America, Mammut pacificus sp. nov. is herein recognized, with specimens identified throughout California and from two localities in southern Idaho. This new taxon differs from the contemporaneous M. americanum in having narrower teeth, most prominently in M3/m3, as well as six sacral vertebrae, femur with a proportionally greater mid-shaft diameter, and no mandibular tusks at any growth stage. All known Pleistocene Mammut remains from California are consistent with our diagnosis of M. pacificus, which indicates that M. americanum was not present in California.

Abstract

The structure of the jatrophane diterpenoid (ES2), C46H56O15, has ortho­rhom­bic (P212121) symmetry. The absolute configuration in the crystal has been determined as 2R,3R,4S,5R,7S,8S,9S,13S,14S,15R [the Flack parameter is −0.06 (11)]. The mol­ecular structure features intra­molecular O—H⋯O and C—H⋯O hydrogen bonding. In the crystal, C—H⋯O hydrogen bonds link the mol­ecules into supra­molecular columns parallel to the a axis. One of the acet­oxy substituents is disordered over two orientations in a 0.826 (8):0.174 (8) ratio.

Abstract

Background: In 2011, the YMCA of the United States adopted physical activity standards for all their afterschool programs (ASPs), which call for children to accumulate 30 minutes of moderate-to-vigorous physical activity (MVPA) while attending YMCA ASPs. The extent to which youth attending YMCA ASPs achieve this standard is unknown.

Methods: Using a cluster-stratified design, 20 ASPs were sampled from all YMCA-operated ASPs across South Carolina (N = 102). ASPs were visited on four unannounced, nonconsecutive weekdays. Accelerometer-derived minutes spent in MVPA were dichotomized to ≥30 min/d of MVPA and <30 min/d of MVPA. Program characteristics were measured through document review and direct observation and compared to MVPA levels using random-effects quantile regression. Results: Boys (n = 607) and girls (n = 475) accumulated a median of 25.3 and 17.1 min/d of MVPA, respectively, which translated into 33% (range 6.2%-67.3%) and 17% (0%-42.6%) achieving the 30 min/d of MVPA standard, respectively. Increase in time scheduled for activity (10.7-11.7 min/d of MVPA), limited sedentary choices during activity time (6.9-8.9 min/d of MVPA), and staff activity-promotion training (4.8-7.9 min/d of MVPA) were associated with higher accumulated minutes of MVPA for boys and girls. Program revenue, percent activity structure that was for free play, and indoor/outdoor space were inconsistently related to meeting the MVPA standard. Conclusions: Modifiable programmatic structures were associated with higher amounts of MVPA. These findings suggest that simple programmatic changes could help ASPs to achieve the MVPA standard, regardless of infrastructure or finances.
