High serum creatinine concentration is associated with metabolic perturbations in dogs.

Background: The kidneys have many essential metabolic functions, and metabolic disturbances during decreased renal function have not been studied extensively.

Objectives: To identify metabolic changes in blood samples with increased serum creatinine concentration, indicating decreased glomerular filtration.

Animals: Clinical samples analyzed using a nuclear magnetic resonance (NMR) based metabolomics platform.

Activation of Blood Coagulation After Aneurysmal Subarachnoid Hemorrhage: A Prospective Observational Trial of Rotational Thromboelastometry.

Objective: Aneurysmal subarachnoid hemorrhage (aSAH) has been reported to actuate blood coagulation. Rotational thromboelastometry (ROTEM) is a dynamic hemostatic test that can differentiate various coagulation abnormalities. For example, increased coagulation activity can be detected as a wider amplitude of tracing (maximal clot firmness [MCF]).

Grey matter volume in early human visual cortex predicts proneness to the sound-induced flash illusion.

Visual perception can be modulated by sounds. A drastic example of this is the sound-induced flash illusion: when a single flash is accompanied by two bleeps, it is sometimes perceived in an illusory fashion as two consecutive flashes. However, there are strong individual differences in proneness to this illusion.

Electromagnetic responses to invisible face stimuli during binocular suppression.

When two incompatible monocular images compete for perceptual dominance, one can dominate awareness while the other is suppressed and invisible. It has been suggested that binocular suppression of this kind involves competitive neuronal interactions at multiple levels of the visual processing hierarchy. Here we asked whether in such situations, complex stimulus information is still preserved at advanced visual processing stages despite competitive interactions at early levels of the visual system.

Control of red fox (Vulpes vulpes) fertility with cabergoline: dose response and timing of intervention.

Cabergoline, a potent dopamine agonist and inhibitor of prolactin secretion, was investigated as a potential fertility control agent in the red fox ( Vulpes vulpes). Sixty silver fox vixens were selected randomly and artificially inseminated. Cabergoline was fed to groups of 12 vixens in a minced beef ration either as a single dose of 25, 50 or 100 microg kg(-1), or a dose of 50 microg kg(-1) that was repeated 2 days later (2 x 50 microg kg(-1)).
