Passive Stiffness In Drosophila Indirect Flight Muscle Reduced By Disrupting Paramyosin Phosphorylation, But Not By Embryonic Myosin S2 Hinge Substitution, Yudong Hao, Mark S. Miller, Douglas M. Swank, Hongjun Liu, Sanford I. Bernstein, David W. Maughan, Gerald H. Pollack

High passive stiffness is one of the characteristic properties of the asynchronous indirect flight muscle (IFM) found in many insects like Drosophila. To evaluate the effects of two thick filament protein domains on passive sarcomeric stiffness, and to investigate their correlation with IFM function, we used microfabricated cantilevers and a high resolution imaging system to study the passive IFM myofibril stiffness of two groups of transgenic Drosophila lines. One group (hinge-switch mutants) had a portion of the endogenous S2 hinge region replaced by an embryonic version; the other group (paramyosin mutants) had one or more putative phosphorylation sites near the …

Postexercise Insulin Action In African-American Women, Rebecca E. Hasson, Patty S. Freedson, Barry Braun

African Americans are more insulin resistant than Caucasians. A single bout of moderate-intensity exercise reduces insulin resistance in sedentary Caucasian individuals. The impact of a single bout of exercise on insulin resistance has never been studied in African Americans. The purpose of this experiment was to evaluate the impact of a single bout of exercise on insulin resistance in African-American women. DESIGN: Insulin resistance was assessed in 10 sedentary, over-weight or obese African-American women during a sedentary and exercise condition over a two-day period. During the sedentary condition, participants fasted overnight and sat quietly in the laboratory for 75 minutes. …
Acsm's Metabolic Calculations Handbook, Stephen Glass, Greg Dwyer
Acsm's Metabolic Calculations Handbook, Stephen Glass, Greg Dwyer
Stephen C Glass
This handbook provides a step-by-step approach to using metabolic equations, from basic math principles to applying the equations to an exercise plan. Chapters focus separately on each equation, provide an easy-to-follow process of solving, and demonstrate the varied uses of the equation in clinical as well as fitness settings.
Each chapter includes a set of problems that focus on real-world applications of the equation. Step-by-step problem solution explanations are provided at the end of each chapter. A comprehensive exam at the end of the book tests the reader's skill in using the equations.
The Inclusion Of Women Cyclists In The Olympics, Shelley Lucas
The Inclusion Of Women Cyclists In The Olympics, Shelley Lucas
Shelley Lucas
This paper provides preliminary findings from my study of the International Olympic Committee's (IOC) decision to allow women cyclists to compete in the Olympic Games. Male cyclists had contested both road and track cycling events since the resumption of the modern games in 1896, but women were not allowed to compete until 1984—and initially, they were limited to participating in the road race only.

Pka-Mediated Erk1/2 Inactivation And Hsp70 Gene Expression Following Exercise, C.W. Melling, Matthew Krause, Earl Noble
Pka-Mediated Erk1/2 Inactivation And Hsp70 Gene Expression Following Exercise, C.W. Melling, Matthew Krause, Earl Noble

Exercise induces the expression of the cardioprotective protein, Hsp70, through the activation of its transcription factor HSF1. Recently, we reported that administration of a protein kinase A (PKA) inhibitor suppressed exercise-induced hsp70 gene expression, suggesting a role for PKA in the regulation of HSF1 activation in vivo. While the mechanism by which PKA regulates HSF1 is unclear, studies in vitro have reported that HSF1 is phosphorylated on two serine residues by mitogen activated protein kinases (MAPKs); ERK1/2 (ser307) and JNK/SAPK (ser363). As PKA is a regulator of these protein kinases, the current study examined the role of PKA in their …

We have developed a magnetic resonance imaging (MRI) technique for imaging Feridex (superparamagnetic iron oxide [SPIO])-labeled islets of Langerhans using a standard clinical 1.5-Tesla (T) scanner and employing steady-state acquisition imaging sequence (3DFIESTA). Both porcine and rat islets were labeled with SPIO by a transfection technique using a combination of poly-l-lysine and electroporation. Electron microscopy demonstrated presence of SPIO particles within the individual islet cells, including beta-cells and particles trapped between cell membranes. Our labeling method produced a transfection rate of 860 pg to 3.4 ng iron per islet, dependent on the size of the islet. The labeling procedure did …
