Tocopherols are plant secondary metabolites that are known collectively as
vitamin E. Tocopherol compounds act as potent antioxidants by quenching free
radicals and protecting fatty acids from oxidative damage. In humans (in vivo)
tocopherols protect membrane lipids from breaking down, while in oils (in vitro)
tocopherols protect fatty acids from...
This exploratory study described the protected living environments of segregated Alzheimer/Dementia Units (ADUs) and compared them to selected physical aspects of the larger institutions in which they were housed. A nonrandom, purposive sample used in this study included 99 nursing homes with ADUs in 34 states. Data were collected using...
This study explored the influence of motivations on the volunteer experience. The relationship among motivations. volunteer satisfaction, acceptance and support of the organizational goals, and outcomes of success in the volunteer role (pattern of participation and ombudsman effectiveness) were explored using Multiple Linear Regression analyses. Motivational Systems Theory (Ford, 1992)...
Identifying habitat and spatial requirements of wildlife species across multiple spatial scales is a challenging, yet crucial component of wildlife management. Habitat use of bats is particularly difficult to study, and managing habitat to conserve bats is especially challenging because bats are highly vagile organisms that exploit several different types...
Dedicated to the preservation and promotion of many of the nation’s most threatened and endangered species, the W.L. Finley National Wildlife Refuge is highly invested in the management of some of the last remaining upland prairies once prevalent throughout Oregon's Willamette Valley. More than a century of land fragmentation, fire...

The relative enrichment of skin sebaceous gland lipids with deuterium-labeled α-tocopherol was compared with plasma enrichment to evaluate the delivery of vitamin E to skin. For the first week of this study, each subject consumed a daily dose of deuterated vitamin E (150 mg of an equimolar mixture of RRR-α-[5-(C²H₃)]-(d₃)...
The Long House explores belonging and commitment. Jennifer Hawley, an American graduate student in linguistic anthropology, arrives in the early 1990s in Long Awan, a Dayak village in the remote highlands of Borneo. Her research concerns oral history among Punan families, traditionally nomadic, which have recently decided to settle in...
To determine whether extreme endurance exercise induces lipid peroxidation, we studied 14 athletes (5 females: 9 males) during a 50 km ultramarathon (trial 1) and during a sedentary protocol (trial 2) one month later. At dinner the evening before the race (or sedentary trial), subjects consumed vitamin E labeled with...
Two experiments were conducted to determine the effect of various levels of vitamin E on egg yolk. A diet of corn-flax-soybean meal was fed to layers and α-tocopherol content in eggs, egg production, and egg quality were evaluated. In experiment 2, vitamin E toxicity was also determined. In experiment 1,...
