Biological Invasions And Biocultural Diversity: Linking Ecological And Cultural Systems, Jeanine Pfeiffer, Robert Voeks
Biological Invasions And Biocultural Diversity: Linking Ecological And Cultural Systems, Jeanine Pfeiffer, Robert Voeks

Study of the ecological and economic effects of invasive species has paralleled their progressively pervasive influence worldwide, yet their cultural impacts remain largely unexamined and therefore unrecognized. Unlike biological systems, where the ecological consequences of biological invasions are primarily negative, from an ethnoscientific standpoint, invasive species' impacts on cultural systems span a range of effects. Biological invasions affect cultural groups in myriad, often unpredictable and at times contradictory ways. This review groups case studies into a conceptual matrix suggesting three categorically different cultural impacts of invasive species. Culturally impoverishing invasive species precipitate the loss or replacement of culturally important native …

Healthy People 2010 breastfeeding goals include 50% exclusive breastfeeding at 6 months. In California, US, Santa Clara County Women, Infants, and Children (SCCWIC) data indicated Asian participants had low (5.6%) 6-month breastfeeding rates. To examine infant-feeding practices, Vietnamese breastfeeding peer counselors surveyed 133 Vietnamese SCCWIC participants (≥ 18 years old, nonpregnant, < 28 months postpartum) using a structured questionnaire regarding intentions, attitudes, and subjective norms toward breastfeeding. Results indicated that 75% initiated breastfeeding in the hospital (33% exclusively, 42% partially), and 25% exclusively formula fed. At survey time, 49% had terminated breastfeeding (average duration 4.4 months). Feeding intentions during pregnancy predicted feeding method used (P < .001). Most prenatal advice was from SCCWIC employees, friends, and doctors who supported breastfeeding. Most postnatal advice was from nurses who supported breastfeeding and bottle-feeding equally. Stronger control beliefs, peer counseling, and education were correlated with breastfeeding (P < .001). Improved postdelivery hospital advice may further increase breastfeeding initiation and duration.
Assessing Osteoporosis Learning Needs And Preferences Of Exercise Physiologists, P D. Sollis, C J. Cisar

Research has revealed substantial knowledge deficits regarding osteoporosis among various healthcare professionals, such as physicians, nurses, and physical therapists. However, no previous studies have addressed the levels of knowledge regarding osteoporosis among exercise physiologists working in a cardiopulmonary rehabilitation setting. It is essential that exercise physiologists have a thorough understanding of osteoporosis so they can ensure client safety and provide accurate information to the client and support group. The purpose of this project was to evaluate the levels of knowledge about osteoporosis among exercise physiologists working with clients who are at high risk for fragility fractures. Ninety-six exercise physiologists (female …
The N-Terminus Of Apolipoprotein A-V Adopts A Helix-Bundle Molecular Architecture, Kasuen Wong, J. A. Beckstead, D. Lee, P. M.M. Weers, E. Guigard, C. M. Kay, R. O. Ryan

Previous studies of recombinant full-length human apolipoprotein A-V (apoA-V) provided evidence of the presence of two independently folded structural domains. Computer-assisted sequence analysis and limited proteolysis studies identified an N-terminal fragment as a candidate for one of the domains. C-Terminal truncation variants in this size range, apoA-V(1-146) and apoA-V(1-169), were expressed in Escherichia coli and isolated. Unlike full-length apoA-V or apoA-V(1-169), apoA-V(1-146) was soluble in neutral-pH buffer in the absence of lipid. Sedimentation equilibrium analysis yielded a weight-average molecular weight of 18811, indicating apoA-V(1-146) exists as a monomer in solution. Guanidine HCl denaturation experiments at pH 3.0 yielded a one-step …
