Medical assessment in the blink of an eye

By on Tuesday, June 18th, 2013 | No Comments

Have you ever thought that you knew something about the world in the blink of an eye? It turns out that radiologists can do this with mammograms, the x-ray images used for breast cancer screening. Cytologists, who screen micrographic images of cervical cells to detect cervical cancer, have a similar ability. A new study takes a closer look at the skill these specialists have.

Boosting body’s natural flu killers as way to offset virus mutation problem

By on Thursday, May 23rd, 2013 | No Comments

The known difficulty in fighting influenza (flu) is the ability of the flu viruses to mutate and thus evade various medications that were previously found to be effective. Researchers at the Hebrew University of Jerusalem have shown recently that another, more promising, approach is to focus on improving drugs that boost the body’s natural flu killer system.

Nanoparticles In Action

By on Monday, April 29th, 2013 | No Comments

The macroscopic effects of certain nanoparticles on human health have long been clear to the naked eye. What scientists have lacked is the ability to see the detailed movements of individual particles that give rise to those effects…

Hundreds of alterations and potential drug targets to starve tumors identified

By on Tuesday, April 23rd, 2013 | No Comments

A massive study analyzing gene expression data from 22 tumor types has identified multiple metabolic expression changes associated with cancer. The analysis, conducted by researchers at Columbia University Medical Center (home of the Herbert Irving Comprehensive Cancer Center), also identified hundreds of potential drug targets that could cut off a tumor’s fuel supply or interfere with its ability to synthesize essential building blocks. The study was published in the online edition of Nature Biotechnology.

New drug combination therapy developed to treat leukemia

By on Thursday, April 18th, 2013 | No Comments

A new, pre-clinical study suggests that a novel drug combination could lead to profound leukemia cell death by disrupting the function of two major pro-survival proteins. The effectiveness of the therapy lies in its ability to target a pro-survival cell signaling pathway known as PI3K/AKT/mTOR, upon which the leukemia cells have become dependent.

Cold winters freezing out breast cancer treatment

By on Thursday, April 18th, 2013 | No Comments

For women diagnosed with estrogen receptor positive breast cancer, tamoxifen is an essential drug used in treatment and prevention. Currently, tamoxifen is used in a one-size-fits-all approach where the same dose is prescribed for every patient. New research has found that in addition to patient-specific genetic factors, lack of exposure to vitamin D during the long winter months affects the body’s ability to metabolize the drug.
