Lutz, Peter L., and Liscia Manuel. Maintenance of adenosine A1 receptor function during long-term anoxia in the turtle brain. Am. J. Physiol. 276 (Regulatory Integrative Comp. Physiol. 45): R633–R636, 1999.—It has been established that adenosine has a critical role in the extraordinary ability of the turtle brain to survive anoxia. To further investigate this phenomenon we compared rat and turt...

Whole cell recording techniques were employed to measure whole cell (Gw) and specific membrane (Gm) conductance in turtle and rat pyramidal neurons in slices. Results indicate that rat neurons are 4.2 times more conductive compared with turtle neurons at 25 degrees C, which is accentuated by temperature, so that rat neurons at 37 degrees C are 22 times more conductive than turtle neurons at 15 ...

Green turtle fibropapillomatosis is a neoplastic disease of increasingly significant threat to the survivability of this species. Degenerate PCR primers that target highly conserved regions of genes encoding herpesvirus DNA polymerases were used to amplify a DNA sequence from fibropapillomas and fibromas from Hawaiian and Florida green turtles. All of the tumors tested (n = 23) were found to ha...

To better understand the role of radial glial (RG) cells in the evolution of the mammalian cerebral cortex, we investigated the role of RG cells in the dorsal cortex and dorsal ventricular ridge of the turtle, Trachemys scripta elegans. Unlike mammals, the glial architecture of adult reptile consists mainly of ependymoradial glia, which share features with mammalian RG cells, and which may cont...

background & aim : although the literature provides evidence-based guidance for bathing infants, it is important to be aware of cultural differences what may arise when caring for infants with a diverse family background. the aim of this study was to examine the correlation between social support and state anxiety in mothers’ practices in newborn baby bathing. methods & materials : the descript...

Except for the brief period of egg-laying, five species of turtle are strictly marine: namely, the green turtle (Chelonia mydas), the loggerhead turtle (Caretta carettd), Ridley's turtle (Lepidochelys olivacea), the hawksbill turtle (L. imbricatd) and the leatherback turtle (Dermochelys coriacea). Reptiles in the sea, like marine fish and marine birds, have a high intake of electrolytes; yet, a...

Developing sea turtle embryos only successfully hatch within a relatively narrow temperature range, rendering this immobile life stage vulnerable to the vagaries of climate change. To accurately predict the potential impact of climate change on sea turtle egg mortality, we need to fully understand the thermal tolerance of developing embryos. We reviewed the literature on this topic, and found t...

We examined sea turtle consumption and illegal trade in Baja California Sur (BCS) using data from (1) bimonthly surveys at beaches, fishing camps and dumpsites and (2) semi-structured interviews with fishermen. From March 2006 to February 2008, we found the carcasses of 1014 sea turtles; the meat of 461 of these turtles (45.5%) had been consumed. The East Pacific green turtle Chelonia mydas was...

background & aim: one of the factors of affecting maternal anxiety is a history of fetal death or neonatal death. this anxiety affects fetal and maternal health. by consideration the impact of anxiety on fetal and maternal health and the lack of protective activities in this field, this study was done to determine the impact of adaptation with pregnancy educational package on anxiety and matern...

background: reptiles, especially turtles that inhabit both on land and water, have made some special adaptations. many people keep turtles as pets. therefore, the anatomical knowledge of turtles should be more carefully evaluated and used for therapeutic purposes. one of these turtles is european pond turtle (emys orbicularis). most of vital systems are enclosed by the carapace and the plastron...
