Organic osmolytes as compatible, metabolic and counteracting cytoprotectants in high osmolarity and other stresses
Tập 208 Số 15 - Trang 2819-2830 - 2005
Paul H. Yancey
SUMMARYOrganic osmolytes are small solutes used by cells of numerous water-stressed organisms and tissues to maintain cell volume. Similar compounds are accumulated by some organisms in anhydrobiotic, thermal and possibly pressure stresses. These solutes are amino acids and derivatives,polyols and sugars, methylamines, methylsulfonium compounds and urea. Except for...... hiện toàn bộ
The physiology of climate change: how potentials for acclimatization and genetic adaptation will determine ‘winners’ and ‘losers’
Tập 213 Số 6 - Trang 912-920 - 2010
George N. Somero
SUMMARYPhysiological studies can help predict effects of climate change through determining which species currently live closest to their upper thermal tolerance limits, which physiological systems set these limits, and how species differ in acclimatization capacities for modifying their thermal tolerances. Reductionist studies at the molecular level can contribute...... hiện toàn bộ
Oxygen- and capacity-limitation of thermal tolerance: a matrix for integrating climate-related stressor effects in marine ecosystems
Tập 213 Số 6 - Trang 881-893 - 2010
Hans‐Otto Pörtner
SUMMARYThe concept of oxygen- and capacity-dependent thermal tolerance in aquatic ectotherms has successfully explained climate-induced effects of rising temperatures on species abundance in the field. Oxygen supply to tissues and the resulting aerobic performance characters thus form a primary link between organismal fitness and its role and functioning at the eco...... hiện toàn bộ
The Propulsion of Sea-Urchin Spermatozoa
Tập 32 Số 4 - Trang 802-814 - 1955
J. Gray, Gregory J. Hancock
ABSTRACT The movement of any short length of the tail of a spermatozoon of Psammechinus miliaris and the characteristic changes which it undergoes during each cycle of its displacement through the water can be described in terms of the form and speed of propagation of the bending waves which travel along the tail (Gray, 1953, 1955); the form of the w...... hiện toàn bộ
Isozymes of mammalian hexokinase: structure, subcellular localization and metabolic function
Tập 206 Số 12 - Trang 2049-2057 - 2003
John E. Wilson
SUMMARY The first step in metabolism of glucose (Glc) is usually phosphorylation,catalyzed by hexokinase. However, the Glc-6-P produced can then enter one or more of several alternative pathways. Selective expression of isozymic forms of hexokinase, differing in catalytic and regulatory properties as well as subcellular localization, is likely to be ...... hiện toàn bộ
The role of gibberellin signalling in plant responses to abiotic stress
Tập 217 Số 1 - Trang 67-75 - 2014
Ellen Colebrook, Stephen G. Thomas, Andrew L. Phillips, Peter Hedden
Plant hormones are small molecules that regulate plant growth and development, as well as responses to changing environmental conditions. By modifying the production, distribution or signal transduction of these hormones, plants are able to regulate and coordinate both growth and/or stress tolerance to promote survival or escape from environmental stress. A central role for the gibberellin...... hiện toàn bộ
The origin of allometric scaling laws in biology from genomes to ecosystems: towards a quantitative unifying theory of biological structure and organization
Tập 208 Số 9 - Trang 1575-1592 - 2005
Geoffrey B. West, James H. Brown
SUMMARYLife is the most complex physical phenomenon in the Universe, manifesting an extraordinary diversity of form and function over an enormous scale from the largest animals and plants to the smallest microbes and subcellular units. Despite this many of its most fundamental and complex phenomena scale with size in a surprisingly simple fashion. For example, meta...... hiện toàn bộ
The Technique of Free Skin Grafting in Mammals
Tập 28 Số 3 - Trang 385-402 - 1951
R. E. Billingham, P. B. Medawar
ABSTRACT Methods are described for the execution of free skin grafts in rabbits, guinea-pigs and mice. Much of the work in which use has been made of the techniques described above has been generously supported over a period of years by the Department of Plastic Surgery, University of Oxford (Prof. T. Pomfret Kilner, F...
The aerodynamic effects of wing rotation and a revised quasi-steady model of flapping flight
Tập 205 Số 8 - Trang 1087-1096 - 2002
Sanjay P. Sane, Michael H. Dickinson
SUMMARY We used a dynamically scaled model insect to measure the rotational forces produced by a flapping insect wing. A steadily translating wing was rotated at a range of constant angular velocities, and the resulting aerodynamic forces were measured using a sensor attached to the base of the wing. These instantaneous forces were compared with quas...... hiện toàn bộ
The control of flight force by a flapping wing: lift and drag production
Tập 204 Số 15 - Trang 2607-2626 - 2001
Sanjay P. Sane, Michael H. Dickinson
SUMMARYWe used a dynamically scaled mechanical model of the fruit fly Drosophila melanogaster to study how changes in wing kinematics influence the production of unsteady aerodynamic forces in insect flight. We examined 191 separate sets of kinematic patterns that differed with respect to stroke amplitude, angle of attack, flip timing, flip duration and the shape a...... hiện toàn bộ
