Consumption of dairy products decreases as teens reach their twenties

Calcium and dairy products play major roles in health maintenance and the prevention of chronic disease. Because peak bone mass is not achieved until the third decade of life, it is particularly important for young adults to consume adequate amounts of calcium, protein and vitamin D found in dairy products to support health and prevent osteoporosis later in life.

Single gene found to control growth of some cancers

Research led by Ashok Aiyar, PhD, Associate Professor of Microbiology at LSU Health Sciences Center New Orleans, showing that a single gene can control growth in cancers related to the Epstein-Barr virus and that existing therapeutics can inactivate it, will be published in the June 12, 2009 online issue of PLoS Pathogens.

Global Post articles examine Malaria worldwide

Global Post examines the quest for an effective vaccine to fight malaria. According to Global Post, "epidemiologists are pinning their hopes on a malaria vaccine" because "[k]illing mosquitoes, or avoiding bites, is an imprecise solution to malaria."

Scientists create simple chemical system that mimics DNA

A team of Scripps Research scientists has created a new analog to DNA that assembles and disassembles itself without the need for enzymes. Because the new system comprises components that might reasonably be expected in a primordial world, the new chemical system could answer questions about how life could emerge.

Waste disposal protein key to cancer tumor suppression in autophagy

"Taking out the trash" takes on a whole new meaning, as investigators at The Cancer Institute of New Jersey (CINJ) and Rutgers, The State University of New Jersey, have discovered that a waste disposal protein is the key to cancer tumor suppression in a process known as autophagy. CINJ is a Center of Excellence of UMDNJ-Robert Wood Johnson Medical School.

Structure of the HIV protein shell revealed

New research by scientists at The Scripps Research Institute and other institutions provides a close-up look at the cone-shaped shell that is the hallmark of human immunodeficiency virus (HIV), revealing how it is held together - and possible ways to break it apart.

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).

Study finds childhood obesity increases early signs of cardiovascular disease

At a press conference held today at The Endocrine Society's 91st Annual Meeting in Washington, D.C., Nelly Mauras, M.D., Division Chief of Endocrinology at Nemours Children's Clinic in Jacksonville, announced the results of a four year study with findings that show childhood obesity increases early signs of cardiovascular disease. Dr. Mauras' study was chosen for distinction among 5,000 abstracts that were submitted to the national conference.

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.

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.

Discovery of protein profile that may predict whether a cancer will be tamoxifen resistant.

Tamoxifen is a widely used and highly successful drug in the treatment of breast cancer, though resistance to tamoxifen is still a concern in recurrent disease (affecting 25-35% of patients), since therapy resistant metastatic tumor cells are a major cause of death.

New insights into causes of multiple sclerosis

Over 100,000 people suffer from multiple sclerosis in Germany alone. Despite intensive research, the factors that trigger the disease and influence its progress remain unclear.

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.
