Journal Highlight: In vivo diffusion MRI detects early spinal cord axonal pathology in a mouse model of ALS

Date: Nov 8, 2018

Author:

Diffusion magnetic resonance imaging (MRI) exhibits contrast that identifies macro‐ and microstructural changes in neurodegenerative diseases. Previous studies have shown that MR diffusion tensor imaging (DTI) can observe changes in spinal cord white matter in animals and humans affected with symptomatic amyotrophic lateral sclerosis (ALS).

Journal Highlight: Preparation of naturally active melanin nano‐platforms chelated with barium ions as a potential X‐ray‐computed tomography contrast agent

Date: Nov 5, 2018

Author: spectroscopyNOW

PEGylated melanin nanoparticles have been prepared and reacted with barium ions to prepare a CT imaging contrast agent with X‐ray attenuation slightly higher than the commercially available iodinated contrasting agent Iohexol.

Meat adulteration: Substitute meats and allergens

Date: Nov 2, 2018

Author: Steve Down

The adulteration of meat and meat products by other types of meat or allergenic foods such as egg white, soy and milk has been accomplished using a stable-isotope-labelled quantification strategy by scientists in Poland.

Insulin analysis: Dried blood spots

Date: Nov 2, 2018

Author: Steve Down

An LC/MS method has been developed for the analysis of insulin and its synthetic analogues from dried blood spots, which could be applied to doping control, forensic and pharmacological fields.

Flexible, stable: Against cancer

Date: Nov 1, 2018

Author: David Bradley

Various techniques have been used in studies that show how linking therapeutically active molecules to specific antibodies can help them target disease sites, specifically in cancer, and so minimize side effects.

Infrared telescope: Gets the asteroid blues

Date: Nov 1, 2018

Author: David Bradley

It takes an infrared telescope to study a blue asteroid and that is exactly what an international team led by the University of Arizona's Lunar and Planetary Laboratory has done using NASA's Infrared Telescope Facility on Mauna Kea in Hawaii and the Tillinghast telescope, operated by the Smithsonian Astrophysical Observatory on Mount Hopkins in Arizona.

Electrifying your gut: MRI monitors digestive aid

Date: Nov 1, 2018

Author: David Bradley

Electrical stimulation could solve many gastrointestinal problems for millions of people around the world. Now, magnetic resonance imaging (MRI) studies have taken a closer look at how such therapy affects the stomach when the vagus nerve is stimulated.

Feathered friends: X-raying the missing link

Date: Nov 1, 2018

Author: David Bradley

Modern birds evolved from theropod dinosaurs, of which the Tyrannosaurus rex is perhaps the most famous. They descended via creatures such as Archaeopteryx. Now, a new species of that grouping that more closely resembled the modern bird has been examined by UK scientists in a three-dimensional synchrotron X-ray study.
