New findings show that eating a high-fat diet beginning at puberty speeds up the development of breast cancer and may actually increase the risk of cancer similar to a type often found in younger adult women.
The research comes from the Breast Cancer and the Environment Research Program at Michigan State University and is published in the current online issue of Breast Cancer Research. (more…)
Sometimes the cure can be worse than the disease. Pharmaceutical drugs are known for their potential side effects, and an important aspect of personalized medicine is to tailor therapies to individuals to reduce the chances of adverse events. Now researchers from North Carolina State University have updated an extensive toxicology database so that it can be used to track information about therapeutic drugs and their unintentional toxic effects.
“Environmental science actually shares a common goal with drug makers: to improve the prediction of chemical toxicity,” says Dr. Allan Peter Davis, lead author of a paper on the work and the biocuration project manager of the Comparative Toxicogenomics Database (CTD) in NC State’s Department of Biological Sciences.

ANN ARBOR — A tiny, transparent fish embryo and a string of surprises led scientists to a deeper understanding of the perplexing link between low calcium and colon cancer.
By studying zebrafish embryo skin, University of Michigan researchers decoded cell messages underlying abnormal colonic cell growth of the kind that can lead to tumors and colon cancer in calcium deficient individuals. They have also tested this new mechanism in human colon cancer cells. (more…)
For youth dealing with obesity who need extra help losing weight, experts suggest a multidisciplinary approach in which care is provided by several health specialists. However, the logistics of traveling to multiple appointments, even if just across town, can be a barrier to receiving care, especially for low-income families.
UCLA researchers who work with this patient population set up a pilot program using telehealth technology — a secure system that allowed patients to see and speak with their health care providers at UCLA over a computer from their local health clinic — to evaluate if such a system could be an effective strategy to help overcome these issues.

Abnehmen klingt so leicht und ist in der Realität für viele doch ein lebensbeherrschendes Thema. Der aus dem Fernsehen bekannte Choreograph Detlef D Soost hat nun ein Diätprogramm gestartet, welches auf Bewegung, Ernährung und Motivation setzt. Wie speziell die Ernährung bei der “10 Weeks Body Change” – Diät (kurz: 10wbc) aussieht, finden sie hier. (more…)
Human papillomavirus, or HPV, which can cause cervical cancer in women, is also known to cause anal cancer in both women and men. Now, a study led by researchers at the UCLA School of Nursing has found that older HIV-positive men who have sex with men are at higher risk of becoming infected with the HPVs that most often cause anal cancer.
The researchers also report that smoking increases the risk of infection with specific types of HPV among both HIV-infected and uninfected older men by up to 20 percent. This is the first large U.S. study of a group of HIV-infected and uninfected men between the ages of 40 and 69 who have sex with men. Study participants were examined twice a year for up to 25 years.

Ob China, Arktis oder Südafrika – und vermutlich auch bei Ihnen zu Hause: PFC-Chemikalien lassen sich weltweit nachweisen. Sie gelangen in Hausstaub, Trinkwasser und Blut, weil sie in großen Mengen in der Textilproduktion eingesetzt werden. Greenpeace wollte wissen, wie viel davon in unserer Outdoor-Kleidung steckt und hat Jacken und Handschuhe ins Labor geschickt.
In allen 17 Produkten wiesen zwei unabhängige Labore per- und polyfluorierte Chemikalien (PFC) und andere Schadstoffe nach. An neun der 17 Proben hat Greenpeace erstmals testen lassen, ob die Giftstoffe aus den Textilien auch an die Luft abgegeben werden. Auch das ist der Fall. (more…)
‘Deformability cytometry’ can closely analyze more than 1,000 cells per second
A team of researchers from UCLA and Harvard University have demonstrated a technique that, by measuring the physical properties of individual cells in body fluids, can diagnose cancer with a high degree of accuracy. (more…)
