UA-led study grapples with health effects of low-intensity warfare

For nearly two decades, Ivy Pike, an associate professor of anthropology at the University of Arizona, has been studying ethnic groups in rural northern Kenya to understand how violence shapes the health of those eking out a living there.

Disease-free, overall survival inferior for black women with HR-positive breast cancer

SAN ANTONIO – Black women with hormone receptor (HR)-positive breast cancer had worse disease-free and overall survival, according to data presented at the CTRC-AACR Annual San Antonio Breast Cancer Symposium, held Dec. 9-13, 2009.

"Black women had a higher risk for disease recurrence and inferior survival compared with women of other races," said Joseph A. Sparano, M.D., professor of medicine and women's health at Albert Einstein Medical College of Medicine and associate chairman of the Department of Oncology at Montefiore Medical Center in Bronx, N.Y.

Scientists identify natural anti-cancer defenses

Montreal, December 11, 2009 – Canadian researchers have discovered a novel molecular mechanism that prevents cancer. In the December 11 edition of the prestigious journal Molecular Cell, scientists from the Université de Montréal and the Université de Sherbrooke explain how they found that the SOCS1 molecule prevents the cancer-causing activity of cytokines, hormones that are culprits in cancer-prone chronic inflammation diseases such as Crohns, in smokers and people exposed to asbestos.

MDC researchers identify a scaffold regulating protein disposal

How does a cell manage to identify and degrade the diverse types of defective proteins and thus protect the body against serious diseases? The researchers Sabine C. Horn, Professor Thomas Sommer, Professor Udo Heinemann and Dr. Ernst Jarosch of the Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch, Germany, have now found a crucial piece in this puzzle. In an enzyme complex that plays a critical role in the quality control of proteins, they discovered a scaffold regulating the identification and disposal of various defectively produced proteins.

Anti-estrogens may offer protection against lung cancer mortality

SAN ANTONIO – Anti-estrogens as therapy for breast cancer may also reduce the risk of death from lung cancer, according to study results presented at the CTRC-AACR San Antonio Breast Cancer Symposium, held here Dec. 9-13, 2009.

"We found a reduction in lung cancer mortality among women treated with anti-estrogens for breast cancer. This work builds on previous studies that had suggested estrogens have a role in lung cancer development and progression," said Elisabetta Rapiti, M.D., M.P.H., medical researcher with the Geneva Cancer Registry, University of Geneva, Switzerland.

NICE guidelines ration affordable osteoporosis drugs

Los Angeles, London, New Delhi, Singapore and Washington DC (December 11, 2009) – Low cost osteoporosis drugs are strictly rationed for the under 75s, and UK physicians hampered by restrictive guidelines, according to findings which appear today in the journal Therapeutic Advances in Musculoskeletal Disease, published by SAGE. A leading Cambridge University bone health expert has outlined flaws in NICE osteoporosis treatment guidance, which limits options for many postmenopausal women in the under-75 age bracket.

New inherited eye disease discovered

University of Iowa researchers have found the existence of a new, rare inherited retinal disease. Now the search is on to find the genetic cause, which investigators hope will increase understanding of more common retinal diseases.

The findings appeared in the Nov. 9 issue of the Archives of Ophthalmology.

The macula, located within the retina, is an area of high-resolution central vision that is needed to read or drive, for example. This area is damaged in more common retinal conditions such as macular degeneration and can be damaged by diabetes.

Europe's flora is becoming impoverished

Halle/Saale. With increasing species richness, due to more plant introductions than extinctions, plant communities of many European regions are becoming more homogeneous. The same species are occurring more frequently, whereas rare species are becoming extinct. It is not only the biological communities that are becoming increasingly similar, but also the phylogenetic relations between regions.

New management methods extend blackberry season

CORVALIS, OR—Fruit growers' profits have traditionally been limited by the seasons, particularly in colder climates where growing seasons can be short. Thanks to researchers and fruit breeders, newly developed varieties are being introduced that offer growers the ability to produce fruit during the offseason—resulting in economic bonuses for both producers and consumers. Fresh examples are the new varieties of blackberry called "primocane-fruiting", which bear fruit on current-season canes, or primocanes.

Moderate weight loss in obese people improves heart function

Obese patients who lost a moderate amount of weight by eating less and exercising more improved their cardiovascular health, says a study at Washington University School of Medicine in St. Louis.

New research identifies modifiable risk factors for heart disease

Emerging research on cardiovascular risk factors and treatment effects are helping clinicians gain a better understanding of which patients are most likely to benefit from close monitoring, lifestyle changes and/or additional therapeutic interventions.

Blood stem-cell transplant regimen reverses sickle cell disease in adults

A modified blood adult stem-cell transplant regimen has effectively reversed sickle cell disease in 9 of 10 adults who had been severely affected by the disease, according to results of a National Institutes of Health study in the Dec. 10 issue of the New England Journal of Medicine. The trial was conducted at the NIH Clinical Center in Bethesda, Md., by NIH researchers at the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), the National Heart, Lung and Blood Institute (NHLBI), and the National Institute of Allergy and Infectious Diseases.

Understanding apples' ancestors

FORT COLLINS, CO—Wild Malus orientalis—species of wild apples that could be an ancestor of today's domesticated apples—are native to the Middle East and Central Asia. A new study comparing the diversity of recently acquired M. orientalis varieties from Georgia and Armenia with previously collected varieties originating in Russia and Turkey narrows the large population and establishes a core collection that will make M. orientalis more accessible to the breeding and research communities.

The future of organic ornamental plants

ORONO, ME—Whether plants are grown for food or ornamental use, conventional agricultural production methods have the same environmental impact. Pesticides, herbicides, and chemical fertilizers can find their way into the air and groundwater, ultimately affecting the environment, wildlife, and communities.
