The utility of green fluorescent protein in transgenic plants

Abstract: The green fluorescent protein (GFP) from the jellyfish Aequorea victoria has proven to be a powerful tool in plant genetic transformation studies. This paper reviews the history and the progression of the expression of GFP variants in transgenic plants. The distinguishing features of the most useful GFPs, such as those including the S65T chromophore mutation and those with dual excitation peaks, are discussed. The review also focuses on the utility of GFP as a visual selectable marker in aiding the plant transformation process; GFP has been more important in monocot transformation compared with dicot transformation. Finally, the potential utility of new fluorescent proteins is speculated upon.

Eccentric exercise effect on blood oxidative-stress markers and delayed onset of muscle soreness.

Abstract: LEE, J., A. H. GOLDFARB, M. H. RESCINO, S. HEGDE, S. PATRICK, and K. APPERSON. Eccentric exercise effect on blood oxidative-stress markers and delayed onset of muscle soreness. Med. Sci. Sports Exerc., Vol. 34, No. 3, pp. 443– 448, 2002. Purpose: This study examined the effects of a single bout of high-intensity eccentric exercise (EE) on blood protein carbonyls, glutathione status, and muscle damage indicators to ascertain whether blood markers of oxidative stress are elevated at the time delayed onset of muscle soreness (DOMS) occurs. Methods: Eight healthy men (26.5 1.5 yr) performed 60 eccentric contractions at ~135-150% dominant arm maximum isometric force (MIF) using their nondominant arm elbow flexors. DOMS, range of motion (ROM), MIF, and blood were obtained before, immediately after, and 24, 48, 72, and 96 h after the EE. Blood samples were analyzed for plasma creatine kinase (CK) activity, and protein carbonyls (PC), and erythrocyte glutathione status. Results: A significant decrease in MIF occurred at all times after the EE. ROM decreased from 24 to 96 h, and DOMS increased 24 to 72 h in the nondominant arm as indicated by a repeated measure ANOVA. Plasma CK activity peaked at 72 h (1620 500 IU·L 1 ) compared with baseline (154 27 IU·L 1 ). Erythrocyte-reduced glutathione (GSH) concentration was not significantly affected by the EE but tended to decrease 23% by 24 h and continued at this level for 96 h. Oxidized glutathione (GSSG) and total glutathione were unchanged over time. A significant increase in plasma PC occurred at 24 and 48 h after eccentric exercise. Conclusions: The results suggest that 60 EE at 135–150% MIF can result in DOMS, with decreased muscle function and increases in plasma PC at 24 and 48 h without alterations in blood glutathione status.

Generating science-based growth: an econometric analysis of the impact of organizational incentives on university–industry technology transfer

Abstract: In recent years, there has been a rapid rise in commercial knowledge transfers from universities to practitioners or university/industry technology transfer (UITT), via licensing agreements, research joint ventures, and startups. In a previous study in 1999, the authors outlined a production function model to assess the relative efficiency of UITT and conducted field research to identify several organizational factors that could enhance the effectiveness of university management of intellectual property portfolios. This paper extends this framework and evaluates the impact of organizational incentives on the effectiveness of UITT. It is found that universities having more attractive incentive structures for UITT, i.e. those that allocate a higher %age of royalty payments to faculty members, tend to be more efficient in technology transfer activities. University administrators who wish to foster UITT should be mindful of the importance of financial incentives.

Adjustment to College in Students With ADHD

Abstract: Objective: To examine college adjustment in students reporting an ADHD diagnosis and the effect of medication treatment on students' adjustment. Method: 1,648 first-semester freshmen attending a public and a private university completed a Web-based survey to examine their adjustment to college. Results: Compared with 200 randomly selected control students, 68 students with ADHD reported more academic concerns and depressive symptoms. This was explained by higher rates of inattentive symptoms among students with ADHD and was unrelated to hyperactive-impulsive symptoms. Among students with ADHD, medication treatment was not related to better adjustment or diminished ADHD symptoms. The contribution of inattention to academic concerns and depressive symptoms remained significant when controlling for personality traits. Conclusion: Students with ADHD experience greater academic performance concerns and depressive symptoms during the transition to college. Medication treatment did not appear to diminish ADHD sy...
