Metabolic Impact Of Protein Feeding Prior To Moderate-Intensity Treadmill Exercise In A Fasted State: A Pilot Study, Bradley T. Gieske, Richard A. Stecker, Charles R. Smith, Kyle E. Witherbee, Patrick S. Harty, Robert Wildman, Chad M. Kerksick

Faculty Scholarship

Background

Augmenting fat oxidation is a primary goal of fitness enthusiasts and individuals desiring to improve their body composition. Performing aerobic exercise while fasted continues to be a popular strategy to achieve this outcome, yet little research has examined how nutritional manipulations influence energy expenditure and/or fat oxidation during and after exercise. Initial research has indicated that pre-exercise protein feeding may facilitate fat oxidation while minimizing protein degradation during exercise, but more research is needed to determine if the source of protein further influences such outcomes.

Methods

Eleven healthy, college-aged males (23.5 ± 2.1 years, 86.0 ± 15.6 kg, 184 …

The Evolution Of Molecular Compatibility Between Bacteriophage Φx174 And Its Host, Alexander Kula, Joseph Saelens, Jennifer Cox, Alyxandria M. Schubert, Michael Travisano, Catherine Putonti

Biology: Faculty Publications and Other Works

Viruses rely upon their hosts for biosynthesis of viral RNA, DNA and protein. This dependency frequently engenders strong selection for virus genome compatibility with potential hosts, appropriate gene regulation and expression necessary for a successful infection. While bioinformatic studies have shown strong correlations between codon usage in viral and host genomes, the selective factors by which this compatibility evolves remain a matter of conjecture. Engineered to include codons with a lesser usage and/or tRNA abundance within the host, three different attenuated strains of the bacterial virus ФX174 were created and propagated via serial transfers. Molecular sequence data indicate that biosynthetic …

Animal Agriculture And American Health: The Search For Sustainable Protein, Britta Brinkmann

Biology: Student Scholarship & Creative Works

This study examines the impact large-scale animal agriculture has on the environment. It links the environment and health. The goal is to find protein sources that are sustainable and nutritious in order to replace typical meat and dairy products. A study is proposed to measure the impact of the typical American diet, a vegan diet, an insect-supplemented diet and a diet heavy in seafood.

Neuromuscular Adaptations Following Training And Protein Supplementation In A Group Of Trained Weightlifters, Christopher B. Taber, Kevin Carroll, Brad H. Deweese, Kimitake Sato, Charles Stuart, Mary Howell, Kenton Hall, Caleb D. Bazyler, Michael H. Stone

ETSU Faculty Works

The purpose of this study was to examine the effects of a recovery supplement compared with a placebo on muscle morphology in trained weightlifters. Vastus lateralis and muscle fiber cross sectional area of type I and type II fibers were compared between groups using a series of 2 × 2 (group × time) repeated measure ANOVAs. Both groups on average improved cross-sectional area of the vastus lateralis, type I and type II muscle fibers from pre-to-post but individual response varied within both groups. Greater magnitude of changes in type I and type II muscle fibers were observed for the placebo …

Mobilization And Role Of Starch, Protein, And Fat Reserves During Seed Germination Of Six Wild Grassland Species, Ming Zhao, Hongxiang Zhang, Hong Yan, Lu Qiu, Carol C. Baskin

Biology Faculty Publications

Since seed reserves can influence seed germination, the quantitative and qualitative differences in seed reserves may relate to the germination characteristics of species. The purpose of our study was to evaluate the correlation between germination and seed reserves, as well as their mobilization during germination of six grassland species (Chloris virgata, Kochia scoparia, Lespedeza hedysaroides, Astragalus adsurgens, Leonurus artemisia, and Dracocephalum moldavica) and compare the results with domesticated species. We measured starch, protein, and fat content in dry seeds and the initial absorption of water during imbibition. Starch, soluble protein, fat, and soluble …

Hard-Sphere-Like Dynamics In Highly Concentrated Alpha-Crystallin Suspensions, Preeti Vodnala, Laurence Lurio, Michael C. Vega, Elizabeth Gaillard

Faculty Peer-Reviewed Publications

The dynamics of concentrated suspensions of the eye-lens protein alpha crystallin have been measured using x-ray photon correlation spectroscopy. Measurements were made at wave vectors corresponding to the first peak in the hard-sphere structure factor and volume fractions close to the critical volume fraction for the glass transition. Langevin dynamics simulations were also performed in parallel to the experiments. The intermediate scattering function f(q,τ) could be fit using a stretched exponential decay for both experiments and numerical simulations. The measured relaxation times show good agreement with simulations for polydisperse hard-sphere colloids.

The Candida Albicans Stress Response Gene Stomatin-Like Protein 3 Is Implicated In Ros-Induced Apoptotic-Like Death Of Yeast Phase Cells, Karen A. Conrad, Ronald Rodriguez, Eugenia C. Salcedo, Jason M. Rauceo

Publications and Research

The ubiquitous presence of SPFH (Stomatin, Prohibitin, Flotillin, HflK/HflC) proteins in all domains of life suggests that their function would be conserved. However, SPFH functions are diverse with organism-specific attributes. SPFH proteins play critical roles in physiological processes such as mechanosensation and respiration. Here, we characterize the stomatin ORF19.7296/SLP3 in the opportunistic human pathogen Candida albicans. Consistent with the localization of stomatin proteins, a Slp3p-Yfp fusion protein formed visible puncta along the plasma membrane. We also visualized Slp3p within the vacuolar lumen. Slp3p primary sequence analyses identified four putative S-palmitoylation sites, which may facilitate membrane localization and are conserved features …

An Investigation Of Atomic Structures Derived From X-Ray Crystallography And Cryo-Electron Microscopy Using Distal Blocks Of Side-Chains, Lin Chen, Jing He, Salim Sazzed, Rayshawn Walker

Computer Science Faculty Publications

Cryo-electron microscopy (cryo-EM) is a structure determination method for large molecular complexes. As more and more atomic structures are determined using this technique, it is becoming possible to perform statistical characterization of side-chain conformations. Two data sets were involved to characterize block lengths for each of the 18 types of amino acids. One set contains 9131 structures resolved using X-ray crystallography from density maps with better than or equal to 1.5 Å resolutions, and the other contains 237 protein structures derived from cryo-EM density maps with 2-4 Å resolutions. The results show that the normalized probability density function of block …
