Osteopenia and cancer in children and adolescents

Physicians caring for children with cancer should be on the lookout for signs of bone fragility caused by disease and treatment, according to a new report.

Clarient receives patent for "automated detection of objects in a biological sample"

Clarient, Inc. has announced that it has been granted a new U.S. patent related to the detection and quantification of rare tumor cells in blood and bone marrow.

Survivors of childhood cancers have a ninefold increased risk of developing a secondary sarcoma

Treatments for childhood cancer have resulted in a current overall cure rate of over 70 percent. However, long-term survivors of childhood cancer are at a higher risk of developing a secondary cancer than the general population.

Chemotherapy drug bortezomib packs a one-two punch

Cancer can be wily, and those who treat the disease have amassed a wide array of weapons with which to fight it and kill tumors.

Cell-based bone tissue engineering

In an article in PLoS Medicine, Gert Meijer (University Medical Centre Utrecht, The Netherlands) and colleagues discuss what kind of progress there has been in restoring the function of diseased or damaged bone by bone tissue regeneration.

Aging bones may benefit from whole body vibration device

While running and jumping are some of the best ways to maintain or improve bone strength and help prevent fractures, they aren't the safest activities for the frail, elderly or physically impaired.

Plant-based omega-3 polyunsaturated fatty acids may have a protective effect on bone health

Normally, most of the omega-3 fatty acids in the diet are plant-derived and come mainly from soybean and canola oil. Other sources are flaxseed, flaxseed oil, walnuts and walnut oil.

Researchers replace organ in mice using 'single-parent' stem cells

Researchers at the University of Pennsylvania School of Veterinary Medicine have derived uniparental embryonic stem cells - created from a single donor's eggs or two sperm - and, for the first time, successfully used them to repopulate a damaged organ with healthy cells in adult mice.

Shortening chromosomes cause for earlier cancer onset in families with Li-Fraumeni syndrome

In families with a high incidence of Li-Fraumeni syndrome, the ends of individuals' chromosomes act somewhat like a lit fuse, according to researchers at The Hospital for Sick Children in Toronto. Their findings detail how telomeres, the ends of the chromosomes, shorten with every successive generation, leading to more severe cancers at an earlier age.

Rate of stem cell transplants among African-Americans lower

Lower transplant rates in ethnic communities may be explained somewhat by a lack of suitable anonymous donors, a problem the medical community has long known and been working to address. Surprisingly, the study found the discrepancy in treatment held true even when the transplant was autologous (e.g. self-donated stem cells were used) or when the cells were donated by a relative, typically a sibling.

Smart technology cuts physiotherapy waiting times

Technology with the potential to help cut physiotherapy waiting times has been unveiled by the University of Abertay Dundee.

Scientists discover master switches for adult blood stem cells

Johns Hopkins Kimmel Cancer Center scientists have found a set of "master switches" that keep adult blood-forming stem cells in their primitive state.

Research helps explain origin of self-reactive B cells

Doctors have long wondered why, in some people, the immune system turns against parts of the body it is designed to protect, leading to autoimmune disease.

ViroPharma receives orphan drug designation for Maribavir

ViroPharma Incorporated today announced that the U.S. Food and Drug Administration (FDA) has granted orphan drug designation for maribavir for prevention of cytomegalovirus (CMV) viremia and disease in the populations at-risk.

Effect of physical activities on knee osteoarthritis in older adults

Regular exercise is recommended for middle-aged and older people, but the effect of exercise on the development of osteoarthritis (OA) in older people is unclear, especially if they are overweight.

Scientists test technique for identifying newly recognized DNA variations that may influence disease risk

Rather than focus on errors and alterations in DNA sequence, the new technique highlights variations in the number of copies of a particular gene.

Osteoporosis and men

A McMaster University researcher is alerting men and their doctors that osteoporosis isn't just a woman's problem but that the bone-wasting disease can severely afflict them, too.

Statins slow the progression of aortic valve stenosis

The trial provides the first prospective clinical evidence that aortic valves have an active biology that can be targeted with medical therapy and contradicts research published in 2005 in the New England Journal of Medicine, which concluded statins did not halt the progression of aortic stenosis.

Aromatase inhibitors for treatment of advanced breast cancer in postmenopausal women

Aromatase inhibitors, a type of hormone therapy used to treat advanced breast cancer in postmenopausal women, result in a small but significant increase in overall survival when compared to other hormone treatments, according to a new systematic review of studies.
