Creating an acute energy deficit without stimulating compensatory increases in appetite: is there an optimal exercise protocol?

Recent years have witnessed significant interest from both the scientific community and the media regarding the influence of exercise on subsequent appetite and energy intake responses. This review demonstrates a consensus among the majority of scientific investigations that an acute bout of land-based endurance exercise does not stimulate any compensatory increases in appetite and energy intake on the day of exercise. Alternatively, preliminary evidence suggests that low volume, supramaximal exercise may stimulate an increase in appetite perceptions during the subsequent hours. In accordance with the apparent insensitivity of energy intake to exercise in the short term, the daily energy balance response to exercise appears to be primarily determined by the energy cost of exercise. This finding supports the conclusions of recent training studies that the energy expenditure of exercise is the strongest predictor of fat loss during an exercise programme

Tilapia for Biological Control of Giant Salvinia

In August 1999, giant salvinia ( Salvinia molesta Mitchell) was found along the lower Colorado River in irrigation drainages. To investigate the slow spread and apparent control of giant salvinia in this region, the herbivorous fish, tilapia (Oreochromis niloticus Trewavas), was examined as a biological control agent. The study was conducted in a 5,000-L recirculating system. (PDF contains 4 pages.

Designing and Assessing a Teaching Laboratory for an Integrated Land Use and Transportation Course

The intersection of land use and transportation policy is becoming an increasingly important focus for all urban planners. This focus, however, challenges the academic community to design effective courses that teach the concepts and professional skills required for professional experience. Integrated land use and transportation courses should engage students to develop interdisciplinary skills while becoming familiar with, for example, travel behavior and zoning policies. Laboratory courses (or segments of courses) as part of graduate curricula provide platforms to further emphasize skills. A common pedagogy problem is devising laboratory assignments that are integrative, cumulative, practical, and interesting for students. Furthermore, laboratory projects should introduce students to real-world problems and techniques while exploring broad planning themes. This paper presents uses four years of laboratory segments from a land use-transportation course (LUTC) at the University of Minnesota to evaluate the needs and results of practitioner-oriented land use and transportation planning education. The laboratory used group projects where students proposed integrated developments using air rights above existing (and sunken) urban freeways in the Twin Cities. The projects provided a practitioner-oriented project through a collaborative and reflexive learning process. This article describes the completed projects, as well as the technical skills, integrated approach and visionary planning necessary for successful execution. The students addressed complicated problems associated with large-scale development by researching neighborhood demographics, characteristics, and pertinent regulations. They used their research to analyze traffic impacts, propose zoning regulations, and outline costs and benefits from their proposal using Geographic Information Systems (GIS), statistical analyses, assessor data and traffic engineering manuals. Using the completed student projects and comparisons with other land use-transportation course and laboratory projects the authors demonstrate how these laboratory components serve multiple pedagogy goals.

Social Determinants of Health Associated with HBV Testing and Access to Care among Foreign-born Persons Residing in the United States: 2009 - 2012

Objectives: To describe how select Social Determinants of Health (SDH) are associated with the burden of hepatitis B virus (HBV) infection among foreign-born persons residing in the United States. Methods: Multivariate logistic regression was used to examine the Racial and Ethnic Approaches to Community Health (REACH) 2010 Risk Factor Survey data to investigate the independent relationship between SDH and HBV testing and access to care. Results: HBV infected persons with insurance were more likely to see a physician than those without. Respondents worried about money to pay rent or mortgage were more likely to report HBV infection than individuals who reported they never worry. Compared to English speakers, Spanish-speakers were less likely to report HBV infection, Vietnamese-speakers were more likely to see a physician for HBV infection, and Khmer-speakers were less likely to be tested. Conclusions: Health insurance coverage, worries about paying rent, and language of interview all differentially affect HBV testing and linkages to care among foreign–born persons. Multi-sectorial stakeholder collaborative efforts should integrate resources to provide culturally sensitive health promotion campaigns which may improve HBV related outcomes

Geolocation and Federalism on the Internet: Cutting Internet Gambling's Gordian Knot

Conventional wisdom dictates that the Internet is a medium in which federalism is destined to fail. By virtue of its decentralized design, the Internet naturally resists regulation by a diverse set of government actors. Indeed, courts have reasoned that federalism on the Internet is either technologically impossible or constitutionally prohibited. The emergence of geolocation technologies, which make it possible to quickly, cheaply, and accurately identify an Internet user's location, challenges this dominant understanding and opens the door to new approaches that could radically alter the way electronic commerce is governed. To illustrate this point, this Article explores the ways that such technologies could be used to make Internet gambling regulation more responsive to longstanding federalism principles. As demonstrated below, geolocation technologies have the potential to make Internet gambling law both more effective and more efficient by enabling each state to enforce its own substantive regulations

Prevalence of Asthma Severities in Children and Adolescents in a Wilmington, DE Hospital

Asthma affects over 24 million individuals in the US and the prevalence of the condition is increasing in the US and worldwide. The prevalence of severe persistent asthma, which incurs a significant health and economic burden, is still poorly understood in children and adolescents. We aimed to define the prevalence of asthma severities in children and adolescents in an urban hospital setting as a function of age, sex, race, and ethnicity by assessing prescribed medications as a proxy for asthma severity according to NIH guidelines for care. We found that a plurality of patients across all age groups, sexes, races, and ethnicities were severe persistent asthmatics. We also found that younger individuals as well as those who are African American have higher odds of being moderate to severe asthmatics. This information can be used to generate hypotheses for future studies and can be used to better address patient needs. In addition, these results suggest that a health disparity among African Americans exists that is consistent with other aspects of the condition. To reduce the prevalence of asthma in all populations, future research should place a greater emphasis on identifying more indicative risk factors for prevention, finding strategies to identify asthma at an earlier age, and developing more effective and personalized therapeutics

Effects of an In-season Resistance Training Program on Lower Extremity Power Output in Collegiate Basketball Players

The purpose of this study was to evaluate changes in muscle power performance in a horizontal (forward movement), vertical, and lateral directions in collegiate basketball players due to the presence of an in-season resistance training program (ISRTP). Four basketball teams were recruited for this study. Two women\u27s basketball teams and two men\u27s basketball teams participated with one team in each gender participating in an ISRTP and one team not participating in an ISRTP. Fifty-three collegiate basketball players (Females= 29, Males= 24) were successfully recruited for this project. Subjects were assessed for lower extremity muscle power and muscle strength at pre-season, mid-season and post-season in order to evaluate any changes that occur over the course of a collegiate varsity basketball season. Margaria-Kalaman, single leg horizontal leap, single leg vertical leap, single leg lateral leap, 5-10-5 shuttle run, estimated RM leg press performance data were collected. Statistical analysis was performed with a multivariate analysis of variance with repeated measures. Results show that an in-season resistance training program significantly impacted the changes over the course of the season (p\u3c .001) as well as a significant interaction with ISRTP and gender (p\u3c.001). All six performance measurements showed significant differences between genders, and the presence of an ISRTP had a significant interaction with gender with the 5-10-5 shuttle run, single leg horizontal leap, and the estimated 1RM leg press. The results of this study support implementation of an ISRTP for male basketball players. This study did not reveal benefits of female basketball players participating in an ISRTP during a collegiate varsity basketball season. The difference in gender responses of an ISRTP on collegiate basketball players may be due to a decrease in muscular strength that was observed in male non-ISRTP basketball players, but not male ISRTP, female ISRTP, or female non-ISRTP basketball players
