Age- and sex-related differences in muscle phosphocreatine and oxygenation kinetics during high-intensity exercise in adolescents and adults
Date: Jul 26, 2010
Author:
The aim of this investigation was to examine the adaptation of the muscle phosphates implicated in regulating oxidative phosphorylation, and oxygenation at the onset of high intensity exercise in children and adults.

It is brain surgery
Date: Jul 1, 2010
Author: David Bradley
MRI allows surgeons to safely and effectively operate inside the human brain through small incisions in the natural creases of the eyelid rather than drilling through skull to get to the grey matter at the front of the brain.

NMR metabolic profile of human follicular fluid
Date: Jun 28, 2010
Author:
The metabolic profiles of human follicular fluid samples that were obtained using NMR spectroscopy are analysed in this work. High correlations were found between important intermediaries of the energetic metabolic pathways of the follicle which can indicate the importance of these pathways in oocyte development. Some of these identified metabolites might be useful as biomarkers of the follicle maturation state, allowing the selection of oocytes in order to increase the pregnancy rates in women after in...

Thinking about a good night's sleep
Date: Jun 1, 2010
Author: David Bradley
Even a single night where a person suffers partial sleep deprivation (PSD) is enough to have a negative impact on thinking. A functional magnetic resonance imaging (fMRI) study suggests that as cognition and affective processing are disrupted, sleep pressure must represent a basic physiological constraint of brain function.

Magnetic resonance histology of the adult zebrafish brain: optimization of fixation and gadolinium contrast enhancement
Date: May 24, 2010
Author:
In this study, the authors created the first protocol for optimal imaging of the adult zebrafish brain. This protocol has enabled the team to achieve the highest isotropic resolution for any vertebrate brain and is similar in thickness to traditional histological slices.

Reporting on contrasting MRI enzyme
Date: May 1, 2010
Author: David Bradley
Researchers have developed an extracellular enzymatic gene-reporter system for magnetic resonance imaging (MRI). The system yields strong, reversible contrast changes in response to the expression of secreted alkaline phosphatise. The products of SEAP activity can then be detected using an iron oxide based sensor.

Reliability and precision of pseudo-continuous arterial spin labeling perfusion MRI on 3.0 T and comparison with 15O-water PET in elderly subjects at risk for Alzheimer's disease
Date: Apr 27, 2010
Author:
Pseudo-continuous ASL provides a reliable whole brain CBF measurement in young and elderly adults whose results converge with those obtained with the traditional 15O-water PET perfusion imaging method. It is an alternative method for non-invasive in vivo examination of early pathophysiological changes in AD.

A sound approach to fibroids
Date: Apr 1, 2010
Author: David Bradley
A new interventional radiology tool based on using MRI to guide focused high-energy ultrasound could be used to thermally ablate uterine fibroid tissue and relieve symptoms of this condition without major invasive surgery.

Fat and water magnetic resonance imaging
Date: Mar 23, 2010
Author:
A wide variety of fat suppression and water-fat separation methods are used to suppress fat signal and improve visualization of abnormalities. This article reviews the most commonly used techniques for fat suppression and fat-water imaging.
