Oxygenation Properties Of Hemoglobin From The Turtle Geochelone Carbonaria.

open access: yes, 2015
The oxygen-binding properties of hemoglobin (Hb) from the adult terrestrial turtle Geochelone carbonaria are described. Turtle hemoglobins have a low intrinsic oxygen affinity and a low sensitivity to an endogenous cofactor (ATP) usually present at high ...

Hemoglobin-sulfhydryls from tortoise (Geochelone carbonaria) can reduce oxidative damage induced by organic hydroperoxide in erythrocyte membrane

open access: yes, 2015
Sulfhydryl groups are important to avoid oxidative damage to the cell. In RBC, tert-butyl hydroperoxide (tert-BOOH) and hydrogen peroxide (H2O2) are capable of oxidizing heme and promoting lipid peroxidation.

Morphology and topography of the urinary system in tortoise (Geochelone carbonaria - Spix, 1824)

open access: yes, 2003
Trabalhamos com 8 jabutis, 4 fêmeas e 4 machos da espécie Geochelone carbonaria, para descrição da morfologia macroscópica e microscópica de luz e eletrônica de varredura do rim.

Water balance of the land tortoise Geochelone carbonaria after olfactory bulbectomy.

open access: yesBrazilian journal of medical and biological research = Revista brasileira de pesquisas medicas e biologica, 1995
We have previously shown that olfactory bulbectomy causes a decrease in some metabolic parameters of chelonians. In the present study we evaluate the capacity for water retention of normal land tortoises and of tortoises with long-standing olfactory bulbectomy.

Visual and response-based navigation in the tortoise (Geochelone carbonaria)

open access: yes, 2013
Much research has investigated spatial cognition in mammals and birds. Evidence suggests that the hippocampus plays a critical role in this; however, reptiles do not possess a hippocampus.

Radial-arm-maze behavior of the red-footed tortoise (Geochelone carbonaria)

open access: yes, 2013
The radial-arm maze is an established method for testing an animal's spatial win-shift behavior. Research on mammals, birds, and fish has shown that the mastery of this task is commonly mediated, to different degrees, by two types of strategy: those ...

Involvement Of Available Sh Groups In The Heterogeneity Of Hemoglobin From The Tortoise Geochelone Carbonaria.

open access: yes, 2015
Geochelone carbonaria hemoglobin (Hb) was analyzed by polyacrylamide gel electrophoresis (PAGE) and purified by ion exchange chromatography on CM-cellulose. Seven fractions were obtained using fresh Hb preparations.

Tránsito digestivo en Geochelone carbonaria (Morrocoy) bajo diferentes dietas experimentales

open access: yes, 2010
This study evaluates in captivity the time of digestive transit with different diets in Geochelone carbonaria (red-footed tortoise). A total of nine mature individuals of this species were used, divided at random in three groups.
