Ultrasound gels present low neurotoxicity risk

Experiments in an animal system indicate that there is low risk for neurotoxicity associated with the use of ultrasound gels containing propylene glycol and glycerol, despite the fact that these compounds are neurotoxic in high concentrations.

Amyloid imaging in clinical trials

Ossenkoppele and colleagues comment on the possibilities of amyloid imaging in clinical trials with disease-modifying agents, methodological considerations for reliable longitudinal amyloid imaging and alternative quantitative approaches.

Diagnosing LVH in Children with ESRD

Changes in diastolic wall thickness of less than 1.6 mm or left ventricle mass index of less than 17.7 g/m2 cannot be distinguished from measurement error when monitoring the appearance of left ventricular hypertrophy (LVH) by echocardiography in children with ESRD.

Curcumin for depression

The administration of curcumin to rats after exposure to  chronic unpredictable stress (CUS) stimuli reverses abnormalities in behavior and cerebral glucose metabolism associated with depression and anxiety.

Optimizing left ventricle segmentation in MRI

A conditional random features approach for automatic segmentation of left ventricles integrates shape and motion features to enhance calculations of function and mass which, due to papillary muscles, are often obscured in threshold-based segmentation.
