Romiplostim more effective than standard care for immune thrombocytopenia

A new study finds that an FDA-approved drug to treat the rare autoimmune disorder immune thromobocytopenia (ITP) is more effective than earlier medical therapies in helping patients avoid surgical treatment and significantly improving their quality of life. The paper in the Nov. 11 New England Journal of Medicine reports that treatment with romiplostim, which mimics the effects of a growth factor that regulates platelet production, was more than three times more successful than standard therapy with steroids or immunosuppressive drugs.

Researchers discover key mutation in acute myeloid leukemia

Researchers have discovered mutations in a particular gene that affects the treatment prognosis for some patients with acute myeloid leukemia (AML), an aggressive blood cancer that kills 9,000 Americans annually. The scientists report their results in the Nov. 11, 2010, on-line issue of The New England Journal of Medicine.

Mid-life cholesterol levels not linked to Alzheimer's disease

ST. PAUL, Minn. – Contrary to earlier research, a new, long-term study suggests that cholesterol level in mid-life may not be linked to later development of Alzheimer's disease, according to a study published in the November 10, 2010, online issue of Neurology®, the medical journal of the American Academy of Neurology. However, the results suggest that large decreases in cholesterol levels in old age could be a better predictor of developing the memory-robbing disease.

Colorectal cancer risk increases in prostate cancer patients on androgen deprivation therapy

Men taking androgen deprivation therapy (ADT) for prostate cancer may have an increased risk of colorectal cancer, according to a study published online November 10 in The Journal of the National Cancer Institute.

Androgen deprivation therapy is a widely-prescribed treatment in men with prostate cancer, although its usage for low-risk disease remains controversial, given the adverse side effects, including osteoporosis, cardiovascular disease, diabetes and obesity; the last two are risk factors for colorectal cancer.

Putting the spotlight on membranous nephropathy

The Halpin Foundation and the American Society of Nephrology (ASN) proudly highlight the research advances in membranous nephropathy made possible by The Halpin Foundation-ASN Research Grant, created to help young faculty develop independent research careers. This award provides recipients transition funding toward successful application for an NIH RO1 grant.

Our normal genetics may influence cancer growth, too

COLUMBUS, Ohio – The genes we possess not only determine the color of our eyes and hair and how our bodies grow, they might also influence the changes that occur in tumors when we develop cancer.

A study by researchers at the Ohio State University Comprehensive Cancer Center-Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James) suggests that our normal genetic background – the genetic variations that we inherit – contributes to the kinds of DNA changes that occur in tumor cells as cancer develops.

Stem cell transplants in mice produce lifelong enhancement of muscle mass

A University of Colorado at Boulder-led study shows that specific types of stem cells transplanted into the leg muscles of mice prevented the loss of muscle function and mass that normally occurs with aging, a finding with potential uses in treating humans with chronic, degenerative muscle diseases.

New indicator found for rapidly progressing form of deadly lung disease

ANN ARBOR, Mich. —A diagnosis of idiopathic pulmonary fibrosis is not much better than a death sentence, given a survival rate averaging 4 to 6 years as the disease robs its victim of the ability to breathe.

But researchers at the University of Michigan have discovered a receptor in the immune system that may serve as a marker for a rapidly progressing form of the disease, which causes the body to produce excess fibrous tissue in the lungs.

Sharks and wolves: Predator, prey interactions similar on land and in oceans

CORVALLIS, Ore. – There may be many similarities between the importance of large predators in marine and terrestrial environments, researchers concluded in a recent study, which examined the interactions between wolves and elk in the United States, as well as sharks and dugongs in Australia.

Citywide smoking ban contributes to significant decrease in maternal smoking, pre-term births

AURORA, Colo. (Nov. 10, 2010) – New research released today takes a look at birth outcomes and maternal smoking, building urgency for more states and cities to join the nationwide smoke-free trend that has accelerated in recent years. According to the new data, strong smoke-free policies can improve fetal outcomes by significantly reducing the prevalence of maternal smoking.

DNA repair protein caught in act of molecular theft

DNA repair protein caught in act of molecular theft

Scientists have observed, for the first time, an intermediate stage in the chemical process that repairs DNA methylation damage and regulates many important biological functions that impact health conditions such as obesity, cancer and diabetes.

Research provides new leads in the case against drug-resistant biofilms

PROVIDENCE, R.I. [Brown University] — When a foreign object such as a catheter enters the body, bacteria may not only invade it but also organize into a slick coating — a biofilm — that is highly resistant to antibiotics. Like sophisticated organized crime rings, biofilms cannot be defeated by a basic approach of conventional means. Instead doctors and drug developers need sophisticated new intelligence that reveals the key players in the network and how they operate.

Researchers see ethical dilemmas of providing care in drug detention centers

(Garrison, NY) Organizations that seek to provide health care, food, and other services to people held in drug detention centers in developing countries often face ethical dilemmas: Are they doing more good than harm? Are they helping detainees or legitimizing a corrupt system and ultimately building its capacity to detain and abuse more people?

U of A researchers can predict heart transplant patient's health earlier

Michael Mengel, a pathology researcher with the Faculty of Medicine & Dentistry, has found a new way to analyze biopsies from heart transplant patients by looking at their genes. This allows him to make an early prediction whether the transplant is working.

This is extremely important in heart transplant patients because a successful outcome depends completely on doing a biopsy of the heart tissue and prescribing treatments if necessary. In other organs transplants, doctors can use other measurements.

Guardian angels for seeds

The seeds that you plant in your backyard garden next spring — and farmers sow in their fields — may have a guardian angel that helps them sprout, stay healthy, and grow to yield bountiful harvests. It's a thin coating of chemicals termed a "seed treatment" that can encourage seeds to germinate earlier in the season, resist insects and diseases, and convey other advantages. These new seed defenders are the topic of an article in the current issue of Chemical & Engineering News (C&EN), ACS' weekly newsmagazine.
