Videssa Breast Blood Diagnostic Test for Breast Cancer

Provista Diagnostics, a company based in New York City, has developed the Videssa Breast blood-based proteomic test to detect breast cancer. At present, after an abnormal mammogram doctors are faced with a difficult decision: whether to carry out an invasive biopsy or not. “When a mammogram yields an abnormal result, the challenge for ev (Read more...)

Breast Cancer Detection Using Ultrasound: Interview with Dr. Georgia Giakoumis Spear, NorthShore University Health System

Detecting breast cancer is of vital importance in terms of treating it early and effectively. Mammography is the gold standard in routinely screening women for breast cancer. However, in a subset of women with dense breast tissue, mammography doesn’t work as well as one would hope. In fact, it can miss up to a third […]

Robots Powered by Clinical MRI Machine to Work Inside Body

At the University of Houston researchers are working to develop diagnostic and therapeutic devices that can be steered and powered using the magnetic field of an MRI scanner. So far the researchers have been able to get blocks about two centimeters on a side to move in predetermined ways inside a specially-built box. They hope […]

Individual Control of Magnetic Micromachines Within The Body

Magnetic micromachines can be delivered into the body and then controlled externally using a magnetic field. Such micromachines could be used to deliver a therapeutic agent to a specific location in a minimally invasive manner or control adaptive implants. However, in many cases multiple micromachines may be required. For example, a ‘swarm&rs (Read more...)

DNA Computer Can Sense Multiple Antibody Inputs, With Potential for Smart Drug Delivery

Researchers at the University of Eindhoven in the Netherlands have developed a DNA computer that can respond to the presence of specific antibodies and make calculations, with the potential for intelligent drug delivery in the future. DNA computing involves using DNA molecules and other molecular biological components as molecular circuitry, instea (Read more...)

Magnet-Powered Implant Releases Drugs in Controlled Fashion

Researchers at the University of British Columbia have developed an implantable device designed to release a drug when triggered by an external magnet. The amount of the drug that’s the implant ejects into the body can be controlled by using different strength magnets. Such technology may be of particular use in treating localized conditions (Read more...)

PerkinElmer’s New Vectra Polaris Automated Quantitative Pathology System for Studying Cancer Immunotherapies

PerkinElmer is releasing a new automated quantitative pathology system, the Vectra Polaris. It was developed to help study how cancer immunotherapies are affecting their targets and nearby tissues. The machine is able to detect multiple immunohistochemical stains simultaneously thanks to multispectral imaging using seven colors, allowing for m (Read more...)
