Meeting Abstract 42.1  Saturday, Jan. 5  The role of titin in force enhancement along the length-tension curve. PACE, CM*; MONROY, JA; NISHIKAWA, KC; Northern Arizona University; Northern Arizona University; Northern Arizona University Cinnamon.Pace@nau.edu Force enhancement is when steady state muscle forces are larger after stretch and can result in muscle forces that exceed isometric force at Lo, […]

Meeting Abstract 42.2  Saturday, Jan. 5  The effects of a titin mutation on tremor frequency during shivering thermogenesis TAYLOR, KR*; NISHIKAWA, KC; Northern Arizona University; Northern Arizona University kt375@nau.edu Muscular springs, such as titin, play an important role in determining muscle properties. The muscular dystrophy with myositis (mdm) mouse model is characterized by a deletion in the […]

Meeting Abstract 42.3  Saturday, Jan. 5  Residual force enhancement: evidence for Ca2+-activation of titin FUQUA, R.D.*; MONROY, J.A.; NISHIKAWA, K.C.; Northern Arizona University; Northern Arizona University; Northern Arizona University rene.fuqua@nau.edu When active muscles are stretched, tension increases and then settles to a steady state that is greater than the isometric force at the stretched length. The mechanism […]

Meeting Abstract 42.4  Saturday, Jan. 5  Comparative assessment of Smad expression in two models of muscle atrophy for the blackback land crab, Gecarcinus lateralis COVI, J.A.*; BADER, B.D.; CHANG, E.S.; MYKLES, D.L.; Univ. of North Carolina at Wilmington; Colorado State Univ.; Bodega Marine Laboratory; Colorado State Univ. covij@uncw.edu In decapod crustaceans, reversible atrophy of claw muscle is […]

Meeting Abstract 42.5  Saturday, Jan. 5  Cardiac, Slow and Fast Troponin-T Isoform Expression Patterns in Dog and Rat Extraocular Muscles REISER, PJ*; BICER, S; Ohio State University; Ohio State University reiser.17@osu.edu Mammalian extraocular muscles (EOMs) consist of two distinct layers. Global layer fibers insert directly onto the eyeball and orbital layer fibers insert onto an outer connective […]

Meeting Abstract 41.5  Saturday, Jan. 5  Simulating and Visualising Flapping-Wing Flight PARSLEW, B; The University of Manchester, UK ben.parslew-2@postgrad.manchester.ac.uk Predictive simulation methods have previously been used to model animals walking, running, galloping and hopping. These methods have been applied extensively to the prediction of kinematics of human terrestrial locomotion and, more recently, have been used to simulate […]

Meeting Abstract 41.4  Saturday, Jan. 5  Rorqual whale hydrodynamics and body drag during non-feeding transport, as revealed by Computational Fluid Dynamics (CFD) POTVIN, J*; REYES, P; MCQUILLING, M; GOLDBOGEN, J A; SHADWICK, R E; Saint Louis University; Saint Louis University; Saint Louis University; Cascadia Research Collective; Univ. of British Columbia potvinj@slu.edu Rorqual whales (Balaenopteridae) represent a group […]

Meeting Abstract 41.3  Saturday, Jan. 5  Performance of Thunniform Propulsion: A High Bio-fidelity Experimental Study DELEPINE, M.B.*; BARANNYK, O.L.; SHADWICK, R.E.; Univ. of British Columbia, Vancouver; Univ. of Victoria, BC; Univ. of British Columbia, Vancouver delepine@zoology.ubc.ca Tunas, lamnid sharks and whales are some of the fastest sustained swimming animals. These animals are part of the thunniform propulsion […]

Meeting Abstract 41.1  Saturday, Jan. 5  Locomotion on heterogeneous granular substrates QIAN, F*; GOLDMAN, D/I; Georgia Tech; Georgia Tech qianfeifei1114@gmail.com Natural particulate substrates like deserts are often composed of collections of multi-size particles: fine sand, pebble, and boulders. While much is known about locomotion on hard ground and increasingly on homogeneous granular media like fine sand, the […]
