Turkish Journal of Medical Sciences

It is known that renin-angiotensin system, inflammation, signaling pathways, and genetic predisposition play a major role in the pathogenesis of heart valve disease. Scarring and collagen deposition in the valves and destruction of myocytes may result from the combined effects of rheumatic and degenerative process in heart valve diseases. Prolidase plays an important role in collagen metabolism, matrix remodeling and cell growth. The aim of the study was to comparatively assess the serum prolidase activity in rheumatic and degenerative heart valve diseases. Materials and methods: The study included 26 patients who had undergone valve replacement due to rheumatic etiology (Group …

Restricted Universal Guidelines For Rop Screening: A Possible Misguidance For Middle Income Countries, Ömer Erdeve, Begüm Atasay, Saadet Arsan, Fi̇gen Batuoğlu, Huban Ati̇lla, Tomri̇s Türmen

Turkish Journal of Medical Sciences

The objective of all studies evaluating retinopathy of prematurity (ROP) screening criteria has been to minimize the number of infants screened while missing no patients with ROP who required treatment. Studies supporting the recommendation that screening for ROP could be restricted to infants born at less than 30 weeks of gestation with birth weights of less than 1250 g have been reported recently, especially from Western countries. However, with the lack of local outcome data, application of the new restricted screening guidelines to infants in middle income countries may lead to misguidance. We aimed to investigate ROP screening requirements in …

Trends In Body Fat, Body Mass Index And Physical Fitness Among Male And Female College Students, Peter Pribis, Carol A. Burtnack, Sonya O. Mckenzie, Jerome Thayer

Faculty Publications

There have been many publications in recent years reporting on the quantity of physical activity among college students using indirect indicators such as steps walked per day or time spent on physical activities. The purpose of this study was to describe the trends of physical fitness related to BMI and body fat among university students between 1996 and 2008. The results showed a significant decline in the average fitness levels measured as an estimation of VO2max for male and female students (p < 0.001 for both sexes). The linear trend for BMI by years was not significant for both sexes (p for males = 0.772, p for females = 0.253). On average, in the last 13 years, % body fat was increasing 0.513%/year for males and 0.654%/year for females. There is a significant indirect correlation between the student's VO2max levels and % body fat, r = -0.489; p < 0.001 for males; and r = -0.416, p < 0.001 for females. Approximately 23.9% of the variance in the VO2max levels in males and 17.3% in females can be explained by the variance in % body fat. The results support recent findings that physical fitness among college students is declining and body fatness is increasing. © 2010 by the authors.

Beliefs And Attitudes Toward Vegetarian Lifestyle Across Generations, Peter Pribis, Rose C. Pencak, Tevni Grajales

Faculty Publications

The objective of the study was to examine whether reasons to adopt vegetarian lifestyle differ significantly among generations. Using a Food Frequency Questionnaire (FFQ), we identified that 4% of the participants were vegans, 25% lacto-ovo-vegetarians, 4% pesco-vegetarians and 67% non-vegetarian. Younger people significantly agreed more with the moral reason and with the environmental reason. People ages 41-60 significantly agreed more with the health reason. There are significant differences across generations as to why people choose to live a vegetarian lifestyle. © 2010 by the authors; licensee MDPI, Basel, Switzerland.

The Constitutionalization Of Labour Rights: What Bliss In This Dawn To Be Alive, Harry W. Arthurs

All Papers

In these remarks to an audience of union-side labour lawyers, I caution against excessive optimism concerning the potential of rights-based constitutional litigation to improve the lot of workers. Despite recent pro-labour Charter decisions of the Supreme Court of Canada, litigation will not fundamentally alter the underlying conditions which have disempowered workers and unions. This is not to say that the constitution is irrelevant, but rather that its most significant features are economic and political, rather than juridical.
