Prone Breast Biopsy System Released

Hologic won FDA clearance and is releasing its Affirm prone biopsy guidance system, a product already approved in Europe. The system provides both 2D and 3D image guidance for performing breast biopsies. The system has a relatively wide field of view to more easily access suspect lesions found during 3D mammography exams. The system includes an integrated […]

MRI-Safe Pacemakers Approved

Boston Scientific landed FDA approval for its ImageReady pacing system that includes the ACCOLADE MRI AND ESSENTIO MRI pacemakers and the INGEVITY MRI leads. As the names imply, the devices are safe for use within an MRI scanner (up to 1.5 Tesla) as long as certain precautions are taken. The INGEVITY MRI leads are available in either […]

Intracellular Recordings with Electrodes

Electrophysiology is an invaluable technique for studying the electrical activity of neurons in the brain and has important clinical applications. The use of nanowire and nanotube intracellular electrode recording devices has improved the spatial resolution and sensitivity of electrophysiological techniques. However, intracellular recordings within thick tissues is limited by the length of the nanotube/nanowire electrode, […]

Death to Tumor Cells

  Researchers from the Karlsruhe Institute of Technology, Germany and University of Kiev, Ukraine have developed a new photodynamic substance that may be useful for attacking tumors. Photodynamic therapy typically involves using light to create free radicals out of oxygen. A special substance is delivered to the area of treatment and light is used to activate […]

Molecular Thermometers Made From DNA Strings

  At the University of Montreal scientists have created a DNA-based thermometer that is so tiny that it can be inserted into cells to read the temperature inside. The inspiration came from seeing naturally occurring molecules being used to sense the temperature in the biological world. Such molecules fold and unfold at specific temperatures and so […]

Yoga Reduces Asthma

A new Cochrane Review, published in the Cochrane Library today, suggests that yoga may have a beneficial effect on symptoms and quality of life in people with asthma, but effects on lung function and medication use are uncertain. Asthma still continues to be a is a common chronic disease that affects nearly 300 million people […]

Understanding Dopamine Neurons

Princeton University researchers have found that dopamine -- a brain chemical involved in learning, motivation and many other functions -- also has a direct role in representing or encoding movement. The finding could help researchers better understand dopamine's role in movement-related disorders such as Parkinson's disease. To get a better idea of how the dopamine […]

Prazosin Minimizes Brain Tumors

Researchers chose to study the most common malignant tumors that develop from brain cells, glioblastomas, which represent the fourth most frequent cause of cancer deaths among adults and the second in children. This is due to the inefficacy of current treatments. Indeed, a glioblastoma can resist treatment and reawaken from a very small number of […]

Tissue Imaging to Conquer Kidney Damages

University of Alabama at Birmingham researchers have made a microscopic snapshot of the early renal lipid changes in acute kidney injury, using the laser-scanning method called MALDI, otherwise known as“matrix-assisted laser desorption ionization”  for tissue imaging to localize the changes. Acute kidney injury is a leading cause of hospital illness or death in critically ill […]

New Type of MRI is Born

There is a new scanning technology on it's way which will give a much clearer picture of lung disease has taken a major step forward thanks to scientists at The University of Nottingham. Experts at the Sir Peter Mansfield Imaging Centre have developed a process using specially treated krypton gas as an inhalable contrast agent […]
