Effects of antioxidants and haemoglobin status on the t‐butyl hydroperoxide‐induced oxygen uptake by red blood cells
(1986)
Oxygen uptake by erythrocytes exposed to t‐butyl hydroperoxide (t‐BHP) exhibited an induction period. The rate of oxygen consumption can be reduced by antioxidants and blood plasma. The induction time was not appreciably ...
Effects of the Kupffer cell inactivator gadolinium chloride on rat liver oxygen uptake and content of mitochondrial cytochromes
(1998)
The effect of gadolinium chloride (GdCl3) on the content of rat liver mitochondrial cytochromes was investigated in relation to the basal rate of O2 uptake and Kupffer cell functioning, assessed in liver perfusion studies. ...
Nitro aryl 1,4-dihydropyridine derivatives: Effects of Trypanosoma cruzi
(1997)
A series of nitro aryl 1,4-dihydropyridine derivatives produced inhibition of both cell growth and oxygen consumption on Tulahuen and LQ strains, and clone Dm 28c of epimastigotes of Trypanosoma cruzi. Nicardipine was found ...
Simulation of hypoxia PET-tracer uptake in tumours: Dependence of clinical uptake-values on transport parameters and arterial input function
(Elsevier, 2020)
Poor radiotherapy outcome is in many cases related to hypoxia, due to the increased radioresistance of hypoxic tumour cells. Positron emission tomography may be used to non-invasively assess the oxygenation status of the ...
Influence of glycogen content on the effect of 2,4-dinitrophenol on the oxygen uptake by rat liver slices
(1955)
When liver glycogen was reduced by fasting of the rats or by glyco-genolysis in vitro, 10-4 M DNP had an inhibitory effect on basal oxygen consumption which was proportional to the glycogen content. With initial glycogen ...
Liver and biliary levels of glutathione and thiobarbituric acid reactants after acute lindane intoxication
(1988)
The i.p. administration of 60 mg kg−1 body weight of lindane, the γ‐isomer of hexachlorocyclohexane, to fed rats led to an enhancement of hepatic lipid peroxidation after 24 h of treatment. This was evidenced by significant ...
Effect of phenanthroline substituents on the rate of oxygen uptake by copper(I) complexes
(1976)
The values of the rate constant for the oxidation reaction are reported for a series of substituted bis(phenanthroline)copper(I) complexes. The rate constant increases along the series: 2,9-diCH3 phen < 5-Cl phen < ...
Behavior of indirect maximal oxygen uptake on users of the prosa Program at Universidad de Antioquia, Medellín, Colombia.
(2011-10-20)
Objective: This research work sought to describe the behavior of maximal oxygen uptake (VO2max) in a population of
adults who performed regular physical activity and classify the level of cardio-respiratory fitness.
Methods: ...
Oxygen diffusion in soils: Understanding the factors and processes needed for modeling
(Inst Investigaciones Agropecuarias, 2015)
Oxygen is an important element for plant growth. Reducing its concentration in the soil affects plant physiological processes such as nutrient and water uptake as well as respiration, the redox potential of soil elements ...
