  • NEUROMECHANICAL CHARACTERIZATION of BRAIN DAMAGE in RESPONSE to HEAD IMPACT and PATHOLOGICAL CHANGES Zolochevsky O
    Series «Medicine». Issue 39 Fundamental researches UDC: 617.3:57.089.67:539.3 DOI: 10.26565/2313-6693-2020-39-01 NEUROMECHANICAL CHARACTERIZATION OF BRAIN DAMAGE IN RESPONSE TO HEAD IMPACT AND PATHOLOGICAL CHANGES Zolochevsky O. O., Martynenko O. V. Traumatic injuries to the central nervous system (brain and spinal cord) have received special attention because of their devastating socio-economical cost. Functional and morphological damage of brain is the most intricate phenomenon in the body. It is the major cause of disability and death. The paper involves constitutive modeling and computational investigations towards an understanding the mechanical and functional failure of brain due to the traumatic (head impact) and pathological (brain tumor) events within the framework of continuum damage mechanics of brain. Development of brain damage has been analyzed at the organ scale with the whole brain, tissue scale with white and gray tissue, and cellular scale with an individual neuron. The mechanisms of neurodamage growth have been specified in response to head impact and brain tumor. Swelling due to electrical activity of nervous cells under electrophysiological impairments, and elastoplastic deformation and creep under mechanical loading of the brain have been analyzed. The constitutive laws of neuromechanical behavior at large strains have been developed, and tension-compression asymmetry, as well as, initial anisotropy of brain tissue was taken into account. Implementation details of the integrated neuromechanical constitutive model including the Hodgkin-Huxley model for voltage into ABAQUS, ANSYS and in-house developed software have been considered in a form of the computer-based structural modeling tools for analyzing stress distributions over time in healthy and diseased brains, for neurodamage analysis and for lifetime predictions of diseased brains.

  • Squid Fishing: from Hook to Plate
    FROM HOOK TO PLATE ver the past few years, squid fishing has become less of an oddity and more of a summertime staple on New Hampshire’s coast. Their documented range extends up to Newfoundland, but until recently, the major concentrations of squid stayed south of Cape Cod. Anglers anticipate the arrival of squid in the Piscataqua River in early summer, and they are fished for as far north as mid-coast Maine. Squid jigs can be found in most seacoast New Hampshire tackle shops during the summer. These are as odd looking as the squid themselves, with upward-turned metal pins at the end of the jig in the place of hooks. Squid are fascinating creatures; let’s explore their unique traits and life history a bit before we go fishing. Camouflage, Communication and Courtship The longfin inshore squid (Doryteuthis pealeii) is a fast growing, short lived molluscan inverte- brate. It is a cephalopod (meaning “head foot”), closely related to the octopus and cuttlefish. These creatures all have their feeding and major sensory organs on the part of their bodies to which the tentacles attach. While this peculiar body structure may be the first thing you notice about a squid, the second is likely to be its dazzling ability to camouflage. Squid have “chromatophores,” which are cells dense in pigment. Nerves and muscles control the contraction or dilation of these pigmented sacs, resulting in a change in color or pattern on the creature. This can be done at a very high speed, resulting in what looks like flashing. This behavior serves several purposes, including camouflage, communica- tion and courtship.

LUCIA, Queensland, Australia, 4067. A THESI S SUBMITTED FOR THE DEGREE OF DOCTOR OF PHILOSOPHY WITHIN THE UNIVERSITY OF QUEENSLAND JULY, 1982 DECLARATION This thesis has been prepared in accordance with the rules set out in the Combined Higher Degree Handbook 1982, for the degree of Doctor of Philosophy at the University of Queensland. The work presented is this thesis is entirely my own except where otherwise acknowledged and no part of it has been submitted for any other degree at this or any other university R. A. Watson July 1982 ABSTRACT Two new lepocreadiid digeneans, Tetracerasta blepta, gen. nov., sp. nov. and Stegodexamene callista, sp. nov. are described from the intestines of the long-finned freshwater eel, Anguilla reinhardtii, from the Brisbane River, Queensland, and the Australian bass, Macquaria novemaculeata, from the Richmond River, New South Wales, Australia. Their life-cycles have been elucidated and completed in the laboratory. All developmental stages are described and illustrated. Eggs from adults of these lepocreadiid species were obtained from eels. These hatched and miracidia from them injected a precocious sporocyst into uninfected laboratory-reared prosobranch gastropods, Posticobia brazieri. Following two generations of rediae in the digestive gland of the snail, large ophthalmotrichocercous cercariae were produced. The cercariae of..!.:._ blepta penetrated uninfected tadpoles of Litoria lesueuri and the gudgeons, Hypseleotris compressus and ~ galii.

Crook, it can prove difficult to specify the differences of response of particular neuron types San Francisco State University, given the multiplicity of neurons in the CNS. However, gastropod molluscs such as United States Tibor Kiss, Aplysia, Lymnaea, or Helix, with their large uniquely identifiable nerve cells, make studies Institute of Ecology Research Center on the cellular, subcellular, network and behavioral actions of anesthetics much more (MTA), Hungary feasible, particularly as identified cells may also be studied in culture, isolated from *Correspondence: the rest of the nervous system.

  • Squid Dissection
    SQUID DISSECTION FOR THE TEACHER Discipline Biological Science Theme Scale and Structure Key Concept The investigation of the structure and function of an open ocean animal like the squid can be used to study adaptations for a completely pelagic existence. Synopsis Students work in pairs to dissect a squid and investigate its structure and how all the parts function together to allow the squid to survive and thrive in its open ocean environment. The squid is then honored as the students participate in a Squid Feast. Science Process Skills observing, communicating, comparing, classifying, relating Social Skill Checking for Understanding Vocabulary benthic, cephalopod, invertebrate, mollusc, pelagic, planktonic MATERIALS For INTO the Activities: Monterey Bay Aquarium Video Collection, "Seasons of the Squid" segment (Available for check-out from the MARE library or for purchase from Monterey Bay Aquarium) Squid Dissection 82 ©2001 The Regents of the University of California Anticipatory Chart #1 and #2 (see charts below) copied on large flip chart paper or on the board: Squid Dissection 83 ©2001 The Regents of the University of California For THROUGH the Activities: For each pair of students and one for yourself: One Squid. Available in grocery stores frozen in 3 lb. boxes for about $1 - $1.50/lb. There are about 32-35 squid per box or enough for two classes. Squid are also available fresh in fish markets. Frozen squid are the number one choice, but if only fresh are available, choose the largest and freshest ones and make sure they haven't been cleaned. Keep them in the freezer until the morning you are going to use them.

  • Action Potentials from Tropical and Temperate Squid Axons: Different Durations and Conduction Velocities Correlate with Ionic Conductance Levels Joshua J
    The Journal of Experimental Biology 205, 1819–1830 (2002) 1819 Printed in Great Britain © The Company of Biologists Limited JEB4001 A comparison of propagated action potentials from tropical and temperate squid axons: different durations and conduction velocities correlate with ionic conductance levels Joshua J. C. Rosenthal and Francisco Bezanilla* Departments of Physiology and Anesthesiology, UCLA School of Medicine, Los Angeles, CA 90095, USA *Author for correspondence (e-mail: [email protected]) Accepted 5 April 2002 Summary To determine which physiological properties between the activation kinetics or voltage-dependence of contribute to temperature adaptation in the squid Na+ and K+ currents. Conductance levels, however, did + giant axon, action potentials were recorded from four vary. Maximum Na conductance (gNa) in S. sepiodea was species of squid whose habitats span a temperature range significantly less than in the Loligo species. K+ of 20 °C. The environments of these species can be conductance (gK) was highest in L. pealei, intermediate in ranked from coldest to warmest as follows: Loligo L. plei and smallest in S. sepiodea. The time course and opalescens>Loligo pealei>Loligo plei>Sepioteuthis magnitude of gK and gNa were measured directly during sepioidea. Action potential conduction velocities and rise membrane action potentials. These data reveal clear times, recorded at many temperatures, were equivalent species-dependent differences in the amount of gK and for all Loligo species, but significantly slower in S. gNa recruited during an action potential. sepioidea. By contrast, the action potential’s fall time differed among species and correlated well with the Key words: squid, giant axon, Loligo pealei, Loligo opalescens, thermal environment of the species (‘warmer’ species Loligo plei, Sepioteuthis sepioidea, temperature adaptation, action had slower decay times).
