Example Sentences:
(1) To test the hypothesis that reduced ATP production during anoxia was compensated partly by conserving energy through reduced ion leakage, the rate of K+ leakage was measured in normoxic and anoxic turtle brains in which Na(+)-K(+)-adenosinetriphosphatase was inhibited with ouabain.

(4) We have used these anatomical studies on Pseudemys and Mauremys retina to form a catalogue of neural types for the turtle retina in general.
(5) Na+-K+-ATPase activities are 2- to 2.5-fold higher in rat than in turtle brains.
(6) The male is intermediate between the female and the ancestral condition observed in other turtle species.
(7) Sequence identities of sea turtle GH to other species of GH are 89% with chicken GH, 79% with rat GH, 68% with blue shark GH, 58% with eel GH, 59% with human GH, and 40% with a teleostean GH such as chum salmon.
(8) Animals were permitted 3-8 days to come to a new steady-state body temperature (Tb) which ranged 5-32 degrees C. Least squares regression equation for pHi data are: frog blood, 8.184-0.0206 Tb; frog striated muscle, 7.275-0.0152 Tb; turtle blood, 8.092-0.0207Tb; turtle muscle, 7.421-0.0186 Tb; turtle heart, 7.452-0.0122 Tb; turtle liver, 7.753-0.0233 Tb; turtle esophageal smooth muscle, 7.513-0.0141 Tb.
(9) We replicated DNA fingerprints of snapping turtles (Chelydra serpentina) and hypervariable restriction fragments of red-winged blackbirds (Agelaius phoeniceus) to estimate the between-blot and between-lane components of variance in molecular weights of restriction fragments.
(10) With the onset of anoxia, the well-documented rapid increases in GABA found in mammalian brains were not observed in the turtle brain.
(11) Colonic tissue from the turtle (Pseudemys scripta) was exposed in a Ussing chamber to simultaneously applied static and time-varying magnetic fields.
(12) Responses to monochromatic flashes were recorded intracellularly from double cones in the retina of the turtle, Pseudemys scripta elegans.
(13) Applications to turtle (Pseudemys scripta) striated muscle are also explored.
(14) A preparation of turtle (Chrysemys picta and Pseudemys scripta) brain in which the integrity of the intracortical and geniculocortical pathways in visual cortex are maintained in vitro has been used to differentiate the excitatory amino acid (EAA) receptor subtypes involved in geniculocortical and intracortical synapses.
(15) Transducer currents were recorded in turtle cochlear hair cells during mechanical stimulation of the hair bundle.
(16) In this investigation the effects of aldosterone on H+ transport are examined in vitro in turtle bladder, a urinary membrane in which several of the factors controlling H+ transport have been defined.
(17) Particularly notable is the evidence of hemoglobin D: this hemoglobin (alpha D2 beta II2) is found only in birds, and in two cases in turtles.
(18) We conclude that there is homeostasis of K, Ca, and Mg in the extracellular fluids of normoxic turtle brain, as in other vertebrates, but that this homeostasis fails during long-term anoxia.
(19) In contrast, adult turtles had very low Cytox activity throughout the central nervous system.
(20) The general conclusions drawn from these studies is that renin secretion in this primitive vertebrate is similar to that in mammals with respect to renal tubular and electrolyte mechanisms, but unlike all mammals tested these turtles do not possess an intrarenal baroreceptor component in renin control.
