Early signs that adult bone-marrow stem cells could regenerate brain tissue (p 1432)
Findings of a preliminary study in this week's issue of THE LANCET suggest that transplanted adult bone-marrow cells could regenerate nerve cells in the brains of human stem-cell recipients. These early findings, if confirmed in future research, have implications for the treatment of neurodegenerative disorders such as Parkinson's disease. Ethical... view more... (2004-04-28)
Elasticity imaging identifies cancers and reduces breast biopsies
A new ultrasound technique allows radiologists to accurately distinguish benign from malignant breast lesions. Using elasticity imaging, researchers correctly identified both cancerous and harmless lesions in nearly all of the cases studied. view more (2006-11-28)
High-resolution imaging with contrast agent shows promise in osteoarthritis research
An innovative combination of existing technologies shows promise for noninvasive, high-resolution imaging of cartilage in research on the progression and treatment of the common degenerative disease osteoarthritis. view more (2006-12-05)
Not all fat is created equal
A Temple University study finds fat in obese patients is "sick" when compared to fat in lean patients. view more (2008-08-28)
CU-Boulder research team identifies stem cells that repair injured muscles
A University of Colorado at Boulder research team has identified a type of skeletal muscle stem cell that contributes to the repair of damaged muscles in mice, which could have important implications in the treatment of injured, diseased or aging muscle tissue in humans, including the ravages of muscular dystrophy. view more (2009-03-06)
Factor stimulates cartilage growth from stem cells
A novel growth factor significantly improves the ability of specialized stem cells derived from human fat to be transformed into cartilage cells, according to Duke University Medical Center and Pratt School of Engineering researchers. view more (2006-04-05)
Watching tumors melt away
All standard methods of removing tumors have side effects. Surgical excision under anesthetic leaves a wound - usually extending into adjacent healthy tissue. It also raises the risk of cancerous cells spreading via blood and lymph vessels. The X- or gamma-rays used in radiation therapy have to pass through healthy tissue to reach deeper-lying... view more... (2003-12-01)
Cryopreservation techniques bring hopes for women cancer victims and endangered species
Emerging cryopreservation techniques are increasing hope of restoring fertility for women after diseases such as ovarian cancer that lead to destruction of reproductive tissue. view more (2008-09-10)
Embryonic heart exhibits impressive regenerative capacity
A new study demonstrates that the embryonic mouse heart has an astounding capacity to regenerate, a phenomenon previously observed only in non-mammalian species. view more (2008-10-14)
A gene for metastasis
Colorectal cancer is one of the most prevalent cancers in the Western world. The tumor starts off as a polyp but then turns into an invasive and violent cancer, which often spreads to the liver. view more (2007-08-28)
Paradigm shift: Switch for programmed cell death promotes spread of glioblastoma
Malignant tumors have usually lost their ability to destroy themselves by programmed cell death, or apoptosis. Therefore, tumors are often resistant to chemotherapy or radiation therapy, whose effect is based on forcing tumor cells to commit suicide. view more (2008-03-12)
Moving X-rays to revolutionise the diagnosis of back pain
A new image processing system devised by engineers at the University of Southampton could change the way that back problems are diagnosed and provide a solution to one of the most common causes of work loss in the UK. Low back pain is a significant problem and its cost to society is enormous. However, diagnosis of the underlying causes remains... view more... (2003-03-21)
Cigarette smoking nearly doubles risk for root canal treatment
According to a new study appearing in the April issue of the Journal of Dental Research, cigarette smoking can lead to not only tooth discoloration and gum disease, but also a common dental procedure that helps to heal a diseased tooth-the root canal. view more (2006-02-24)
Fructose metabolism by the brain increases food intake and obesity
The journal Biochemical and Biophysical Research Communications (http://www.elsevier.com/locate/ybbrc) (BBRC), published by Elsevier, will publish an important review this week online, by M. Daniel Lane and colleagues at Johns Hopkins, building on the suggested link between the consumption of fructose and increased food intake, which may... view more... (2009-03-25)
K-State professors discover enzyme responsible for creation of a beetle's hard shell
Kansas State University researchers think their discovery of the enzyme involved in the hardening of a beetle's exoskeleton or cuticle could lead not only to better pest control, but also help create similar strong, lightweight materials for use in aircraft and armor. view more (2005-08-03)
New link found between osteoporosis and coeliac disease
People with coeliac disease may develop osteoporosis because their immune system attacks their bone tissue, a new study has shown. view more (2009-10-08)
Alternatively spliced tissue factor identified as promising new biomarker for aggressive cancers
A recently discovered form of the protein that triggers blood clotting may play a key role in the molecular mechanisms leading to the growth of certain metastatic cancers, according to new research reported by an international team of scientists. view more (2009-10-27)
How embryonic stem cells develop into tissue-specific cells demonstrated
While it has long been known that embryonic stem cells have the ability to develop into any kind of tissue-specific cells, the exact mechanism as to how this occurs has heretofore not been demonstrated. view more (2008-05-13)
New acoustic absorber to improve physiotherapy ultrasound machines
Physiotherapy ultrasound machines are commonplace in medicine and sports injury treatment but limitations with current calibration equipment mean they may be producing inaccurate doses that could lead to further injury. view more (2007-09-25)
Discovery of follicles offers hope of babies for Turner's syndrome girls
Lausanne, Switzerland: Swedish researchers have found that teenage girls with Turner's syndrome still have follicles in their ovaries which may be capable of producing eggs. This discovery offers hope that Turner's syndrome girls may be able to have babies in the future. Mr Julius Hreinsson, an embryologist in the Fertility Unit at Huddinge... view more... (2001-07-03)
