Cardiovascular fitness not affected by cancer treatment

Washington, DC – The cardiovascular fitness level of cancer survivors is not affected by many standard cancer therapies, say researchers from Georgetown University Medical Cancer. That is the finding of a new observational study to be presented today at the American College of Sports Medicine in Seattle.

Immunologists identify biochemical signals that help immune cells remember how to fight infection

DALLAS – May 28, 2009 – Immunology researchers at UT Southwestern Medical Center have discovered how two biochemical signals play unique roles in promoting the development of a group of immune cells employed as tactical assassins.

In their initial response, these immune cells, known as cytotoxic T lymphocytes, or CTLs, kill cells infected with pathogens. They also provide long-term protection against pathogens by "remembering" which proteins the pathogen makes. Targeting the ability of these CTLs to remember the pathogen is one way vaccines protect against infection.

Breastfeeding duration and weaning diet may shape child's body composition

Chevy Chase, MD—Variations in both milk feeding and in the weaning diet are linked to differences in growth and development, and they have independent influences on body composition in early childhood, according to a new study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM).

Non-toxic hull coating resists barnacles, may save ship owners millions

North Carolina State University engineers have created a non-toxic "wrinkled" coating for use on ship hulls that resisted buildup of troublesome barnacles during 18 months of seawater tests, a finding that could ultimately save boat owners millions of dollars in cleaning and fuel costs.

Is cherry juice a new 'sports drink?'

SEATTLE, Wash., May 28, 2009, – Drinking cherry juice could help ease the pain for people who run, according to new research from Oregon Health & Science University presented at the American College of Sports Medicine Conference in Seattle, Wash. The study showed people who drank tart cherry juice while training for a long distance run reported significantly less pain after exercise than those who didn't. Post-exercise pain can often indicate muscle damage or debilitating injuries.

Blacks more likely to opt for life-sustaining measures at end of life

PITTSBURGH, May 28 – When faced with a terminal illness, African-American seniors were two times more likely than whites to say they would want life-prolonging treatments, according to a University of Pittsburgh study available online and published in the June issue of the Journal of General Internal Medicine.

Scientists develop a new HIV microbicide -- and a way to mass produce it in plants

In what could be a major pharmaceutical breakthrough, research published online in The FASEB Journal (http://www.fasebj.org) describes how scientists from St George's, University of London have devised a one-two punch to stop HIV. First the report describes a new protein that can kill the virus when used as a microbicide. Then the report shows how it might be possible to manufacture this protein in quantities large enough to make it affordable for people in developing countries.

Daily alcohol intake can lead to binge drinking

Montreal, May 28, 2009 — Sipping wine, beer or spirits three to four times per week increases the risk of binge drinking, particularly among young men, according to a new study published in the journal Addiction. Researchers from the Université de Montréal and the University of Western Ontario analyzed the drinking habits of Canadians and found that frequent alcohol consumption can lead to binge drinking among all gender and all age groups.

Adult bone marrow stem cells injected into skeletal muscle can repair heart tissue

BUFFALO, N.Y. -- University at Buffalo researchers have demonstrated for the first time that injecting adult bone marrow stem cells into skeletal muscle can repair cardiac tissue, reversing heart failure.

Using an animal model, the researchers showed that this non-invasive procedure increased myocytes, or heart cells, by two-fold and reduced cardiac tissue injury by 60 percent.

Partner status influences women's interest in men

A study by Indiana University neuroscientist Heather Rupp found that a woman's partner status influenced her interest in the opposite sex.

In the study, women both with and without sexual partners showed little difference in their subjective ratings of photos of men when considering such measures as masculinity and attractiveness. However, the women who did not have sexual partners spent more time evaluating photos of men, demonstrating a greater interest in the photos. No such difference was found between men who had sexual partners and those who did not.

Development of DNA drugs gives hope to lupus patients

A generation of DNA-like compounds, class R inhibitory oligonucleotides (INH-ODNs), have been shown to effectively inhibit cells responsible for the chronic autoimmune condition lupus. Researchers writing in BioMed Central's open access journal Arthritis Research & Therapy have demonstrated the anti-inflammatory effects of the INH-ODNs in both in vitro and mouse experiments.

Music played to premature babies may lessen pain and improve feeding habits

Music played to premature babies may help to reduce their pain and encourage better oral feeding, suggests research published ahead of print in the Archives of Disease in Childhood.

Increasing numbers of neonatal units are using music as a method to help improve behavioural and physiological outcomes or to manage pain during common procedures such as circumcision.

The benefits are said to be calmer infants and parents, a stable condition in the child's functions, higher oxygen saturation, faster weight gain and shorter hospital stays.

People with parents who fight are more likely to have mental health problems in later life

People with parents who were violent to each other are more likely to have mental health problems when they grow up, reveals research published in the Journal of Epidemiology and Community Health.

Researchers looked at what impact interparental violence had on people as children by observing their mental health outcomes in adulthood.

A child being exposed to interparental violence is a form of maltreatment with consequences for a child's development, but in some countries it is only seen as a risk factor for later problems with no specific outcomes.

Team develops DNA compounds that could help treat lupus

A research team led by a University of Iowa investigator has generated DNA-like compounds that effectively inhibit the cells responsible for systemic lupus erythematosus -- the most common and serious form of lupus. There currently is no cure for this chronic autoimmune condition that damages the skin, joints and internal organs and affects an estimated one million Americans.

Research suggests new cellular targets for HIV drug development

GAINESVILLE, Fla. — Focusing HIV drug development on immune cells called macrophages instead of traditionally targeted T cells could bring us closer to eradicating the disease, according to new research from University of Florida and five other institutions.

In the largest study of its kind, researchers found that in diseased cells — such as cancer cells — that are also infected with HIV, almost all the virus was packed into macrophages, whose job is to "eat" invading disease agents.
