Certain pesticides double the risk of blood disorder

A study involving 678 individuals who apply pesticides, culled from a U.S. Agricultural Health Study of over 50,000 farmers, recently found that exposure to certain pesticides doubles one's risk of developing an abnormal blood condition called MGUS (monoclonal gammopathy of undetermined significance) compared with individuals in the general population.

Estrogen receptor status may modify how a protein that spurs leukemia behaves in the breast

A protein known to play a role in growth of some types of leukemia appears to have a mixed function in breast cancer development, say researchers from the Lombardi Comprehensive Cancer Center at Georgetown University Medical Center (GUMC).

90 per cent of the world's population won't have access to antivirals in pandemic - generic drugs may help though

Almost 90 per cent of the world's population will not have timely access to affordable supplies of vaccines and antiviral agents in the current influenza pandemic, but it is possible that inexpensive generic drugs that are readily available, even in developing countries, could save millions of lives.

Resveratrol shows potential for significant health benefits

The benefits of alcohol are all about moderation. Low to moderate drinking - especially of red wine - appears to reduce all causes of mortality, while too much drinking causes multiple organ damage. A mini-review of recent findings on red wine's polyphenols, particularly one called resveratrol, will be published in the September issue of Alcoholism: Clinical & Experimental Research; the review is also available at Early View.

Study shows promise for new cancer-stopping therapy

Researchers at Nationwide Children's Hospital and Johns Hopkins University have discovered that delivering a small molecule that is highly expressed in normal tissues but lost in diseased cells can result in tumor suppression.

Genotoxic stress makes your hair go gray

Those pesky graying hairs that tend to crop up with age really are signs of stress, reveals a new report in the June 12 issue of Cell, a Cell Press publication.

Bioprocess increases vaccine yield

Empa researchers have managed to adapt a process for manufacturing certain vaccines - in particular that against Haemophilus influenzæ bacteria - for use in bioreactors, with the result that the yield is enhanced enormously.

Yeast 'DNA damage sensor' provides chemotherapy resistance clue

Cancer Research UK scientists have been part of an international collaboration that has revealed the structure of a protein found in simple yeast cells and shown how it flags up damaged DNA for repair. The results of their study are published in Nature*. The finding may provide clues as to how some cancer cells become resistant to certain chemotherapy drugs.

Researchers discover how prion protein damages brain cells

Scientists at the National Institutes of Health have gained a major insight into how the rogue protein responsible for mad cow disease and related neurological illnesses destroys healthy brain tissue.

Discovery of four new breast cancer targets

Four suspects often found at the scene of the crime in cancer are guilty of the initiation and progression of breast cancer in mice that are resistant to the disease, a team led by scientists at The University of Texas M. D. Anderson Cancer Center reports in the June edition of Cancer Cell.

The 'hijacking mechanism' of HIV-1 pinpointed

Researchers at McGill University and the affiliated Lady Davis Institute for Medical Research at Montreal's Jewish General Hospital - along with colleagues at the University of Manitoba and the University of British Columbia - may have found a chink in the armour of the human immunodeficiency virus type 1 (HIV-1), the microorganism which causes AIDS. They have pinpointed the key cellular machinery co-opted by HIV-1 to hijack the human cell for its own benefit.

Bisphenol A may cause heart disease in women

New research by a team of scientists at the University of Cincinnati (UC) shows that bisphenol A (BPA) may be harmful for the heart, particularly in women.

Potential new way to treat childhood epilepsy

Rutgers researchers have discovered a potential new way to treat childhood epilepsy using a widely available therapeutic drug.

Neuroscientists watch memories form in real time

Our ability to form long-term memories depends on cells in the brain making strong connections with each other. Yet while it's not well understood how those connections are made, lost or changed, the process is known to involve the movement of the AMPA receptor protein to and from those neuronal connections.

51 genes predict breast cancer survival

It may be possible in the future to use a specimen from the tumour to determine which patients with breast cancer have a good chance of overcoming the disease, and which patients should be given more intensive treatments.

Hormone therapy may confer more aggressive properties to prostate tumours

Hormone therapy is often given to patients with advanced prostate cancer. While it is true that the treatment prevents growth of the tumour, it also changes its properties. Some of these changes may result in the tumour becoming more aggressive and more liable to form metastases. This is one of the conclusion of a thesis presented at the Sahlgrenska Academy, University of Gothenburg, Sweden.

A new method for breast cancer biomarker discovery

Three researchers from the Virginia Bioinformatics Institute (VBI) at Virginia Tech have developed and evaluated a new one-step bioanalytical approach that allows them to profile in detail complex cellular extracts of proteins. The method has allowed the scientists to look at how the levels of proteins change in breast cancer cells when they are treated with hormones or cancer drugs like tamoxifen.

Stopping type 1 diabetes damage with vitamin C

Researchers at the Harold Hamm Oklahoma Diabetes Center have found a way to stop the damage caused by Type 1 diabetes with the combination of insulin and a common vitamin found in most medicine cabinets.

Antiretroviral therapy earlier yields better clinical outcomes

A clinical trial has demonstrated that HIV-infected adults in a resource-limited setting are more likely to survive if they start antiretroviral therapy (ART) before their immune systems are severely compromised.

Gene variation associated with resistance to chemotherapy drug in women with breast cancer

Researchers have found links between an individual's genetics and their response to treatment with chemotherapy. The findings, by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, and colleagues, show how a genetic variant, located in the SOD2 gene, may affect how a person responds to the chemotherapy drug cyclophosphamide. Cyclophosphamide is used in the treatment of breast and other cancers.
