Balancing wildlife and bioenergy values on private forestlands in the eastern Upper Peninsula of Michigan

There is interest in developing a reliable, sustainable, domestic U.S. biofuels industry. A domestic biofuels industry has the potential to provide economic, environmental, and national security benefits on a local, regional, national, and global level. The Mascoma Corporation plans to develop a cellulosic ethanol facility in Michigan’s eastern Upper Peninsula. The primary feedstock of the plant site would be trees sourced within a 150 mile supply radius. In the eastern Upper Peninsula, this radius encompasses Alger, Chippewa, Delta, Luce, Mackinac, and Schoolcraft counties. In these six counties there are 1,320,500 acres of NIPF (non-industrial private forestlands). These acres account for 40% of the total timberland in these six counties. Thus it is likely that in order for the successful implementation of a cellulosic ethanol facility the support of local NIPF owners will be necessary. This thesis presents research on how eastern Upper Peninsula forest landowners think about and manage their land. It is based on 48 in-depth interviews with these landowners. The goal was to determine how landowner values and beliefs, on a variety of issues including wildlife management, land management, biofuels development, and climate change, are expressed through both their current management decisions, and possibly their future land management decisions. Some of the values articulated by the landowners in this study included biodiversity protection, conservation of healthy game populations, and the production of high-value timber. Understanding the values and beliefs of landowners in the eastern Upper Peninsula of Michigan is critical for successfully developing a sustainable regional woody bioenergy.

The ins and outs of phosphatidylethanolamine synthesis in Trypanosoma brucei.

Phospholipids are not only major building blocks of biological membranes but fulfill a wide range of critical functions that are often widely unrecognized. In this review, we focus on phosphatidylethanolamine, a major glycerophospholipid class in eukaryotes and bacteria, which is involved in many unexpected biological processes. We describe (i) the ins, i.e. the substrate sources and biochemical reactions involved in phosphatidylethanolamine synthesis, and (ii) the outs, i.e. the different roles of phosphatidylethanolamine and its involvement in various cellular events. We discuss how the protozoan parasite, Trypanosoma brucei, has contributed and may contribute in the future as eukaryotic model organism to our understanding of phosphatidylethanolamine homeostasis. This article is part of a Special Issue entitled Phospholipids and Phospholipid Metabolism.

Nutrition knowledge and attitudes of physician assistants in Texas

Physician Assistants (PAs) are increasingly assuming more responsibilities as "front-line" health providers due to emphasis on primary care and cost-containment in the rapidly changing health care environment. Nutrition plays an important role in health promotion and disease prevention. Primary care providers, including PAs, have enormous potential as nutrition counselors and advocates. There have been no studies to date that address the PAs' adequacy of nutrition education or their attitudes toward the value of nutrition. Therefore, it was the purpose of the study to determine the nutrition knowledge and attitudes of PAs in Texas.^ All certified physician assistants in Texas were eligible for the study. A mailed survey was sent to 1,482 PAs in Texas with a response rate of 54.2%. The sample utilized for data analysis was 764 PAs.^ The study compared the nutrition knowledge mean scores for PAs who graduated from a PA program greater than 11 years ago with those who graduated less than 11 years ago. The study also examined Texas PAs' attitudes about their nutrition education training, the value of nutrition counseling, and their perceived ability to provide such nutrition counseling. Demographic and practice information was collected from the PAs. Demographically, PAs in Texas were found to be comparable to the national population of PAs surveyed in 1996.^ The overall mean level of nutrition knowledge was 70% correct. The mean level of nutrition knowledge was significantly related to the type of PA program that the PA graduated from (i.e., Certificate only or Master's degree level). No significant relationships were found between the mean nutrition knowledge score and age, year of graduation, length of practice, or the type of nutrition education provided in PA program.^ The majority of the PAs surveyed felt that diet and nutrition has an important role in disease prevention and felt that PA programs should place a greater emphasis on nutrition education. Many PAs surveyed were not satisfied with the amount of nutrition education they had received in their PA education programs and were not confident in their ability to provide nutrition counseling to patients.^ Suggestions are offered for improvement in PA nutrition education in the areas of both nutrition knowledge and patient counseling skills. In addition, this study recommends developing and strengthening partnerships between PAs and nutrition organizations. ^

Phosphatidylethanolamine and phosphatidylcholine biosynthesis by the Kennedy pathway occurs at different sites in Trypanosoma brucei

Phosphatidylethanolamine (PE) and phosphatidylcholine (PC) are among the most abundant phospholipids in biological membranes. In many eukaryotes, the CDP-ethanolamine and CDP-choline branches of the Kennedy pathway represent major and often essential routes for the production of PE and PC, with ethanolamine and choline/ethanolamine phosphotransferases (EPT and CEPT, respectively) catalysing the last reactions in the respective pathways. Although the site of PE and PC synthesis is commonly known to be the endoplasmic reticulum (ER), detailed information on the localization of the different phosphotransferases is lacking. In the unicellular parasite, Trypanosoma brucei, both branches of the Kennedy pathway are essential for cell growth in culture. We have previously reported that T. brucei EPT (TbEPT) catalyses the production of ether-type PE molecular species while T. brucei CEPT (TbCEPT) synthesizes diacyl-type PE and PC molecular species. We now show that the two enzymes localize to different sub-compartments of the ER. By expressing a series of tagged forms of the two enzymes in T. brucei parasites, in combination with sub-cellular fractionation and enzyme activity measurements, TbEPT was found exclusively in the perinuclear ER, a distinct area located close to but distinct from the nuclear membrane. In contrast, TbCEPT was detected in the bulk ER.

Lipid topogenesis - 35years on

Glycerophospholipids are the principal fabric of cellular membranes. The pathways by which these lipids are synthesized were elucidated mainly through the work of Kennedy and colleagues in the late 1950s and early 1960s. Subsequently, attention turned to cell biological aspects of lipids: Where in the cell are lipids synthesized? How are lipids integrated into membranes to form a bilayer? How are they sorted and transported from their site of synthesis to other cellular destinations? These topics, collectively termed 'lipid topogenesis', were the subject of a review article in 1981 by Bell, Ballas and Coleman. We now assess what has been learned about early events of lipid topogenesis, i.e. "lipid synthesis, the integration of lipids into membranes, and lipid translocation across membranes", in the 35years since the publication of this important review. We highlight the recent elucidation of the X-ray structures of key membrane enzymes of glycerophospholipid synthesis, progress on identifying lipid scramblase proteins needed to equilibrate lipids across membranes, and new complexities in the subcellular location and membrane topology of phosphatidylinositol synthesis revealed through a comparison of two unicellular model eukaryotes.

Halting Childhood Obesity in Connecticut

The Practicum Project is a supervised service-learning experience that integrates curriculum with hands-on experience in a public health setting. All 2nd year students are expected to work collaboratively in assessing the extent, causes and public health responses to a selected public health problem confronting citizens of Connecticut. The focal topic for the 2005 Project was Control of Childhood Obesity in Connecticut. During this past spring, 25 students of our program, working alongside and in partnership with more than 130 community-based stakeholders across Connecticut, completed 2,083 hours of service-learning in pursuit of answers to 3 questions: Can the present and future burden of childhood obesity be estimated for Connecticut? What is the current capacity of Connecticut’s health and social service system to address the crisis we confront today? Can new policy and regulatory strategies be put forth to reduce the severity and scope of the problem? This occasion and the accompanying report mark the completion of their project and acknowledges the considerable contributions that many have made to the success of this educational experience. Through those combined efforts, students gained experience and skill addressing one of the most significant public health issues of our time; also, they gained insight into the breadth and capacity of our public health system and established invaluable relationships with public health practitioners, agencies and institutions around the state. Their report documents a rich campus-community partnership to advance public health goals.

Health information exchange: Using metrics to address quality of care and return on investment

Health Information Exchange (HIE) will play a key part in our nation’s effort to improve healthcare. The evidence of HIEs transformational role in healthcare delivery systems is quite limited. The lack of such evidence led us to explore what exists in the healthcare industry that may provide evidence of effectiveness and efficiency of HIEs. The objective of the study was to find out how many fully functional HIEs are using any measurements or metrics to gauge impact of HIE on quality improvement (QI) and on return on investment (ROI).^ A web-based survey was used to determine the number of operational HIEs using metrics for QI and ROI. Our study highlights the fact that only 50 percent of the HIEs who responded use or plan to use metrics. However, 95 percent of the respondents believed HIEs improve quality of care while only 56 percent believed HIE showed positive ROI. Although operational HIEs present numerous opportunities to demonstrate the business model for improving health care quality, evidence to document the impact of HIEs is lacking. ^

El entrenamiento de fuerza en la natación

Existen numerosos estudios que demuestran la importancia del entrenamiento de fuerza en la mejora del rendimiento en la natación. El objetivo del entrenamiento de fuerza en natación es por tanto buscar la transferencia en rendimiento de la natación de competición. Sin embargo, aunque los estudios hayan mostrado mejoras significativas con el entrenamiento de fuerza, no se ha demostrado que exista una transferencia específica. No obstante, su introducción en el programa de entrenamiento de un nadador se torna fundamental si se quiere llevar a cabo la máxima optimización posible del rendimiento. Por tanto, el objetivo de este trabajo será mostrar los fundamentos básicos del entrenamiento de fuerza, así como mostrar los métodos para su aplicación en el entrenamiento de la natación.
