  Terrestrial locomotion does not constrain venous return in the American alligator

  Alligator mississippiensis

  The effects of treadmill exercise on components of the cardiovascular (heart rate

  mean arterial blood pressure

  central venous pressure

  venous return) and respiratory (minute ventilation

  tidal volume

  breathing frequency

  rate of oxygen consumption

  rate of carbon dioxide production) systems and on intra-abdominal pressure were measured in the American alligator

  Alligator\nmississippiensis

  at 30°C. Alligators show speed-dependent increases in tidal volume and minute ventilation

  demonstrating that the inhibition of ventilation during locomotion that is present in some varanid and iguanid lizards was not present in alligators. Exercise significantly\nincreases intra-abdominal pressure; however

  concomitant elevations in central venous pressure acted to increase the transmural pressure of the post caval vein and thus increased venous return. Therefore

  despite elevated intraabdominal pressure

  venous return was not limited during exercise in alligators

  as was the case in Varanus exanthematicus and Iguana iguana. Respiratory cycle\nvariations in intra-abdominal pressure

  central venous pressure and venous return indicate that

  at high tidal volumes

  inspiration causes a net reduction in venous return during active ventilation and thus may act to limit venous return during exercise. These results suggest that

  while tonically elevated intra-abdominal pressure induced by exercise does not inhibit venous return

  phasic\nfluctuations during each breath cycle may contribute to venous flow limitation during exercise.

  Over a decade has passed since Powell et al. (Respir Physiol 112:123–134

  1998) described and defined the time domains of the hypoxic ventilatory response (HVR) in adult mammals. These time domains

  however

  have yet to receive much attention in other vertebrate groups. The initial

  acute HVR of fish

  amphibians and reptiles serves to minimize the imbalance between oxygen supply and demand. If the hypoxia is sustained

  a suite of secondary adjustments occur giving rise to a more long-term balance (acclimatization) that allows the behaviors of normal life. These secondary responses can change over time as a function of the nature of the stimulus (the pattern and intensity of the hypoxic exposure). To add to the complexity of this process

  hypoxia can also lead to metabolic suppression (the hypoxic metabolic response) and the magnitude of this is also time dependent. Unlike the original review of Powell et al. (Respir Physiol 112:123–134

  1998) that only considered the HVR in adult animals

  we also consider relevant developmental time points where information is available. Finally

  in amphibians and reptiles with incompletely divided hearts the magnitude of the ventilatory response will be modulated by hypoxia-induced changes in intra-cardiac shunting that also improve the match between O2 supply and demand

  and these too change in a time-dependent fashion. While the current literature on this topic is reviewed here

  it is noted that this area has received little attention. We attempt to redefine time domains in a more ‘holistic’ fashion that better accommodates research on ectotherms. If we are to distinguish between the genetic

  developmental and environmental influences underlying the various ventilatory responses to hypoxia

  however

  we must design future experiments with time domains in mind.

  Most sports have a certain degree of danger associated with them

  due to flying objects and bodies colliding at high speeds. Soccer and water polo are particularly dangerous for one of the most important parts of the human body; the head. Head injury in these sports may stem from contact with the goal posts

  other players

  the side walls (in water polo) or the ground (in soccer). However

  these sports bear a unique danger to the head when compared with other competitive sports due to the nature of ball interaction. Soccer is the only competitive sport that involves and condones purposeful head contact with the ball

  and water polo is one of the only sports that involves ball flight almost exclusively in a plane parallel with head altitude. As a consequence of engaging in these sports

  risk of head injury

  especially concussions due to such ball interactions

  is dramatically increased. In 2009 alone

  hospitals reported 24

  184 cases of soccer head injury

  and 28

  716 cases of water polo head injury (American Association of Neurological Surgeons - AANS). Furthermore

  head trauma in these cases can cause a plethora of disabilities. These can range from loss of motor function to complete paralysis to death in the most severe cases. \n\nThe existence of these serious injuries make it critical to reduce the amount of risk taken when participating in these sports. Specifically

  our team is searching for methods of minimizing the amount of impact force experienced by the head by ball contact. Interestingly

  there is little to no precedent for tests on ball specifications and their implications on impact forces in these two sports.\n\nhttps://lnkd.in/b3KTvEc

  I believe that it is important to articulate the power of comparative and evolutionary physiology and to point out that these approaches are not mutually exclusive to biomedical sciences. Comparative physiology

  at its most basic level

  seeks to discover how animals work

  and

  most importantly

  why animals work the way they do. These two seemingly straightforward questions have far-reaching implications and require a variety of investigative approaches. The comparative physiologist is challenged to determine the details of physiological mechanisms while simultaneously gaining insights into ultimate causation

  i.e. the evolutionary or adaptive significance of a physiological process or trait. This manifold focus on proximal mechanism and ultimate causality requires that comparative and evolutionary physiologists bring to their investigations a diversity of analytical approaches and to effectively integrate molecular

  ecological and evolutionary information.

  who

  at some point in their careers

  have made outstanding contributions of service to the University of California. An outstanding contribution is not defined simply as having served on a large number of Senate Committees

  although such may be one of the factors. It is defined as service which leads to the betterment of the academic and/or personal lives of large segments of the University community.

  Professor James W. Hicks is a highly significant researcher within the field of comparative physiology. During his career he has worked broadly with respiration and circulatory physiology

  and in particular he has contributed new knowledge regarding physiological responses to increased metabolism and the influence of gravity on the circulatory system. Professor James W. Hicks has made a fundamental contribution to our understanding of the function of the heart in reptiles

  and his scientific work is a shining example of the way in which integrative studies at many levels of biological organisation generate understanding of how and why animals function as they do.\n\nJames W. Hicks has published almost 100 articles

  a number of which have been printed in high-profile journals such as Science

  Nature and PNAS. He has played a leading role in a great number of academic forums and been particularly active in the work involved in strengthening cross-disciplinary

  rewarding interaction between comparative physiology and the more clinical physiology practised by medical science.\n\nIn addition to being an excellent researcher

  James W. Hicks is a brilliant lecturer and a fantastic communicator who is capable of providing simple but accurate explanations of complicated issues. He is an extremely active communicator

  and has made lengthy contributions to a variety of programmes produced by the BBC

  Discovery Channel and National Geographic.\n\nIn 1985 James W. Hicks visited Aarhus University for the first time

  since when he has enjoyed close contact with the zoo-physiology group at the university. This has resulted in a great number of joint scientific publications as well as exchanges of students and postdocs.
