d13C and d15N of Pacific halibut skeletal muscle tissue from the Gulf of Alaska, 2018
<p>In 2018, white muscle samples were collected from the lateral musculature of a random sample of up to 4 fish from each survey station of the International Pacific Halibut Commission's Fishery Independent Setline Survey (total n = 1653). Muscle samples were stored at -20°C, thawed, oven-dried to a constant mass at 42°C, and ground to a fine powder. Approximately 0.5 to 1.0 mg of each powdered sample was loaded into a tin capsule for stable isotope analysis. d<sup>13</sup>C and d<sup>15</sup>N values were determined using a Carlo Erba 1110 Elemental Analyzer (Carlo Erba Reagents, CE Instruments, ThermoQuest Italia S.p.A. Milan, Italy) coupled to a Thermo Delta Plus XP IRMS (Thermo Finnigan, Bremen, German) at the University of Wyoming's Stable Isotope Facility (Laramie, Wyoming, USA). Long-term analyses of quality control standards have yielded precisions of 0.3‰ for d<sup>13</sup>C and 0.4‰ for d<sup>15</sup>N. Stable isotope data are presented in ‰ relative to Pee Dee Belemnite for <sup>13</sup>C and atmospheric nitrogen for <sup>15</sup>N.</p>

Dataset and analyses for: Force-field perturbations and muscle vibration strengthen stability-related foot placement responses during steady-state gait in healthy adults
<p>We have collected kinematic data (heel and pelvis markers) from healthy adults during treadmill walking, whilst force-field perturbations and timed muscle vibrations were applied. We assessed the (after-)effects of these two interventions by evaluating foot placement control through outcome measures derived from a regression model which predicts foot placement based on the center-of-mass kinematic state. The data and analyses provided belong to the scientific publication: "Force-field perturbations and muscle vibration strengthen stability-related foot placement responses during steady-state gait in healthy adults". In the manuscript we place these analyses in the context of stability control and speculate on how these trainining interventions may improve stability control in patient populations.</p>

Training of aerobic fitness (VO2max) and muscle strength – a cost/benefit analysis
<p>A systematic literature search in the Ovid Medline, Web of Science and SportDiscus databases was performed, limited to randomized studies of aerobic fitness and strength training, respectively. Studies with at least three "doses" of frequency, duration or intensity of training were examined in order to find out what effect could be expected from the next highest “dose”.</p>
Optimization of an ex vivo gene transfer to the hamstrings tendons muscle remnants: potential for genetic enhancement of bone healing
<p>Human muscle tissue samples obtained from 31 patients was used in this in vitro analytical and experimental study. To optimize transduction protocol, samples from 28 patients were transduced with the adenoviral vector carrying firefly luciferase cDNA (Ad.luc) using different doses, times of transduction and addition of positive ions for transduction enhancement. The optimized protocol was further tested on muscle samples from 3 new patients, which were transduced with Ad.BMP-2. Released bone morphogenetic protein 2 (BMP-2) levels in osteogenic medium were measured every 3 days during the period of 21 days. Expression of osteogenic markers was at day 14 and 21. After 21 days of cultivation, muscle tissue was prepared for immunohistochemical staining for collagen type I (COL-I). </p>
