New mechanism explains how the body prevents formation of blood vessels
By Dross at 2009-11-11 21:40
 

Researchers at Uppsala University, in collaboration with colleagues in Sweden and abroad, have identified an entirely new mechanism by which a specific protein in the body inhibits formation of new blood vessels. Inhibiting the formation of new blood vessels is an important aspect of, for example, cancer treatment. The study is published in the November issue of the journal Molecular Cancer Research.

Intervals between lung cancer diagnosis and treatment displays a health care disparity
By Dross at 2009-11-02 21:49
 

Research published in the November 2009 issue of the Journal of Thoracic Oncology has found that intervals between lung cancer suspicion, diagnosis and treatment may be attributed to health care system discrepancies.

Hepatitis B does not increase risk for pancreatic cancer
By Dross at 2009-11-02 21:48
 

DETROIT – A Henry Ford Hospital study found that hepatitis B does not increase the risk for pancreatic cancer – and that only age is a contributing factor.

The results contradict a previous study in 2008 that suggested a link between pancreatic cancer and previous hepatitis B infection. Hepatitis B is an inflammation of the liver caused by a viral infection.

Study results will be presented at the American Association for the Study of Liver Diseases' Annual Meeting in Boston.

Duke develops nano-scale drug delivery for chemotherapy
By Dross at 2009-11-02 21:47
 

DURHAM, N.C. -- Going smaller could bring better results, especially when it comes to cancer-fighting drugs.

Duke University bioengineers have developed a simple and inexpensive method for loading cancer drug payloads into nano-scale delivery vehicles and demonstrated in animal models that this new nanoformulation can eliminate tumors after a single treatment. After delivering the drug to the tumor, the delivery vehicle breaks down into harmless byproducts, markedly decreasing the toxicity for the recipient.

Brain tumors in childhood leave a lasting mark on cognition, life status
By Dross at 2009-11-02 21:46
 

Survivors have less education, lower income relative to their siblings and survivors of other cancers

WASHINGTON — Brain tumors in childhood cast a long shadow on survivors. The first study of the lasting impact of these tumors -- the most common solid malignancies in childhood -- shows that survivors have ongoing cognitive problems. They also have lower levels of education, employment and income than their siblings and survivors of other types of cancer, according to a report published by the American Psychological Association.

Exercise is good medicine for lymphoma patients
By Dross at 2009-10-29 00:55
 

A healthy dose of exercise is good medicine, even for lymphomaterm patients receiving chemotherapyterm, University of Alberta researchers have found.

The Healthy Exercise for Lymphoma Patients (HELP) trial, a three-year study led by Kerry Courneya, Canada Research Chair in physical activity and cancer in the Faculty of Physical Education and Recreation, found that a regimen of aerobic exercise training produced significant improvements in physical functioning and overall quality of life benefits in patients with lymphoma.

Scientists Are First To Observe The Global Motions Of An Enzyme Copying DNA
By Dross at 2009-10-29 00:55
 

COLUMBUS, Ohio – Scientists here have identified how the motions of an enzyme are related to correctly copying genetic instructions, setting the stage for studies that can uncover what happens when DNA copying mistakes are made.

Perpetuation of DNA mistakes can cause mutations that lead to cancer and other diseases.

High-definition Colonoscopy Detects More Polyps, Mayo Clinic Researchers Say
By Dross at 2009-10-29 00:54
 

High-definition (HD) colonoscopy is much more sensitive than standard colonoscopy in finding polyps that could morph into cancer, say researchers at the Mayo Clinic campus in Florida.

Cholesterol lowering drugs may be useful in the fight against cancer
By Dross at 2009-10-27 22:01
 

Millions of people around the world use medicines based on statins to lower their blood cholesterol, but new research from the University of Gothenburg, published in the prestigious journal PNAS, shows that statins may also be effective in the treatment of cancer.

Statins lower cholesterol by blocking certain enzymes involved in our metabolism. However, they have also been shown to affect other important lipids in the body, such as the lipids that help proteins to attach to the cell membrane (known as lipid modification).

Adding Tool Against Breast Tumors
By Dross at 2009-10-27 22:00
 

At the end of a 10-year, coast-to-coast study of women with an unusual form of breast cancer, Richard J. Barth Jr., M.D., and three fellow researchers are making the case for a particular combination of treatments to stop the tumors in their tracks.

Alcohol activates cellular changes that make tumor cells spread

Researchers at Rush University Medical Center explain link between alcohol and cancer

Alcohol consumption has long been linked to cancer and its spread, but the underlying mechanism has never been clear.

Now, researchers at Rush University Medical Center have identified a cellular pathway that may explain the link.

New research suggests how low doses of radiation can cause heart disease and stroke
By Dross at 2009-10-23 10:05
 

A mathematical model constructed by researchers at Imperial College London predicts the risk of cardiovascular disease (heart attacks, stroke) associated with low background levels of radiation. The model shows that the risk would vary almost in proportion with dose. Results, published October 23 in the open-access journal PLoS Computational Biology, are consistent with risk levels reported in previous studies involving nuclear workers.

59-Year-Old Man with MDS

Study shows how normal cells influence tumor growth
By Dross at 2009-10-23 03:11
 

COLUMBUS, Ohio – It was once thought that the two communities of cells within a cancerous breast tumor – fast-growing malignant cells and the normal cells that surround them – existed independently, without interaction. Then evidence emerged indicating that the normal-looking cells encouraged cells within the tumor to become malignant, but how the one community influenced the other wasn't known.

Sensor biochips could aid in cancer diagnosis and treatment
By Dross at 2009-10-23 02:46
 

It is very difficult to predict whether a cancer drug will help an individual patient: only around one third of drugs will work directly in a given patient. Researchers at the Heinz Nixdorf Chair for Medical Electronics at the Technische Universitaet Muenchen (TUM) have developed a new test process for cancer drugs. With the help of microchips, they can establish in the laboratory whether a patient's tumor cells will react to a given drug. This chip could help in future with the rapid identification of the most effective medication for the individual patient.
