Calcium consumption may cause prostate cancer in Chinese

PHILADELPHIA — Among Chinese men, calcium consumption — even at relatively low levels and from non-dairy food sources such as soy, grains and green vegetables — may increase prostate cancer risk, according to results published in Cancer Research, a journal of the American Association for Cancer Research.

PHILADELPHIA (June 1, 2010)—Lung cancer rates are increasing substantially in women, particularly in non-smoking women, with no known reason for the increase. Now researchers at Fox Chase Cancer Center may have uncovered a critical piece in the puzzle.

HOUSTON - (June 1, 2010) – Understanding how the tumor suppressor protein C/EBP alpha is eliminated in aging livers gives important clues to the mechanism by which cancer occurs in that organ and could point the way to new therapies and prevention, said Baylor College of Medicine (www.bcm.edu) researchers in a report that appears online today in the Journal of Clinical Investigation.

Scientists have learned how a gene widely known for precisely positioning and sculpting various organs also controls the speed of cell division, a finding that could be useful for understanding the explosive growth of cancer cells or why increasing numbers of children are being born with genital and urinary tract malformations.

CHICAGO – Cancer patients who've been told to rest and avoid exercise can – and should – find ways to be physically active both during and after treatment, according to new national guidelines.

Chicago — Aromatase inhibitor-associated arthralgia (AIAA) is a major side effect in breast cancer survivors, producing joint pain so severe that as many as ten percent of women discontinue their therapy prematurely while undergoing treatment with these lifesaving drugs. New research presented by investigators from the University of Pennsylvania's Abramson Cancer Center at the 2010 meeting of the American Society of Clinical Oncology reveals a possible genetic basis for why these side effects occur and shows promise for treating these symptoms without interfering with the drugs' efficacy.

Squirrels show softer side by adopting orphans

Those neighbourhood squirrels you often see fighting over food may not seem altruistic, but new University of Guelph research has found that the critters will actually take in orphaned relatives.

The study by Guelph Prof. Andrew McAdam, along with researchers from the University of Alberta and McGill University, revealed that red squirrels will adopt pups that have lost their mother.

COLD SPRING HARBOR, N.Y. (Tues., June 1, 2010) -- Gel electrophoresis is one of the most important and frequently used techniques in RNA analysis. Electrophoresis is used for RNA detection, quantification, purification by size and quality assessment. Gels are involved in a wide variety of methods including northern blotting, primer extension, footprinting and analyzing processing reactions. The two most common types of gels are polyacrylamide and agarose.

Each year The International Institute for Species Exploration at Arizona State University names the Top 10 new species described in the previous calendar year. The list for 2009 was published to coincide with the 303rd anniversary on May 23rd of the birth of Carl Linnaeus. It contains only two new plant species, one of which was first published in the Botanical Journal of the Linnean Society.

Blood-thinning copycat enters malaria fight

New treatments for malaria are possible after Walter and Eliza Hall Institute scientists found that molecules similar to the blood-thinning drug heparin can stop malaria from infecting red blood cells.

CAMBRIDGE, Mass. — Since the 1990s, a green fluorescent protein known simply as GFP has revolutionized cell biology. Originally found in a Pacific Northwest jellyfish, GFP allows scientists to visualize proteins inside of cells and track them as they go about their business. Two years ago, biologists who discovered and developed the protein as a laboratory tool won a Nobel Prize for their work.

WHAT:In a clinical trial involving HIV-negative volunteers with early-stage syphilis, researchers have found that antibiotic pills (azithromycin) are as effective as penicillin injections in curing early-stage syphilis. The study was supported by the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health.

The University of Navarra, together with the University of Oxford and three other European centres, are taking part in a project to discover the origin of myelodysplasia, an ailment with a predisposition to develop into leukaemia. In the work, patients from 19 hospitals in the north of Spain – including the University Hospital of Navarra - were analysed, as well as from England, Italy, Sweden and Germany.

Ohio scientists hope to counter the re-emerging threat of tuberculosis (TB) with help from proteins from our bodies. In a research report published in the June 2010 print issue of the Journal of Leukocyte Biology (http://www.jleukbio.org), scientists show how the protein CCL5 plays a protective role in helping the body ward off this contagious, airborne disease in the early stages of infection. CCL5 is a member of a large family of proteins responsible for immune cell migration toward infection sites.

COLUMBUS, Ohio – While some Latino immigrants to the United States may be accepted as "white" by the wider society, a new study finds that many of them face discrimination based on skin color.

In fact, the research showed that relatively darker-skinned Latinos earned less than their lighter-skinned counterparts.

The results suggest that the rapid influx of Latino immigrants will shift the boundaries of race in the United States, but will not end skin-color-based discrimination.
