Though thyroid cancer is one of the most curable forms of cancer, side effects including hypothyroidism can be debilitating. In the September issue of The Journal of Nuclear Medicine, a team of researchers from the Netherlands and Belgium reported on a new technique that allows patients to maintain their normal course of thyroid medication prior to and during radioiodine therapy, thus eliminating the risk for most side effects.
Immunoglobulins which are already being used to treat multiple sclerosis may also be able to help patients with Alzheimer's. This, at least, is the finding of a pilot study on five patients at the University of Bonn. The results are set out in the forthcoming edition of the Journal of Neurology, Neurosurgery and Psychiatry (vol. 75, pp. 1472-1474), which also devotes its editorial to this discovery.
A group from the Salk institute illuminates the structural basis for tetraketide cyclization in stilbene synthase, the enzyme that produces resveratrol, the beneficial phytonutrient found in red wine.
With the goal of finding effective drug leads with which to combat SARS, researchers from the University of Hong Kong conducted a chemical genetic screen to isolate compounds with anti-SARS-CoV activity.
Scientists are a step closer to understanding the health benefits of drinking red wine. Researchers funded by the National Science Foundation (NSF) and affiliated with the Salk Institute in San Diego, Calif., have succeeded in converting chalcone synthase, a biosynthetic protein enzyme found in all higher plants, into an efficient resveratrol synthase.
A new study by researchers at Joslin Diabetes Center sheds light on the key mechanisms by which new pancreatic beta cells normally form in response to insulin resistance.
One of the simpler ways to curtail the obesity epidemic could be to cut the volume of sweetened soft drinks and fruit drinks Americans are increasingly consuming, authors of new study say.
Adults eat around twice the amount of fruit and vegetables and less fat and sugar than they did as children, a new study by UK researchers suggests, although many perceive there are still many barriers to healthy eating.
Cases of the Hib infection (haemophilus influenzae type b) among children and adults have risen in recent years, despite a vaccination programme which initially proved successful, say researchers in this week's BMJ.
The science of measuring drug levels in the blood after death is far from robust and based on flawed evidence- leading to likely miscarraiges of justice and conspiracy theories, say forensic scientists in this week's BMJ.
Three out of five Israeli clinicians report using placebos - inactive treatments or drugs - in treating patients, despite the medical profession's official disapproval of their use, say the authors of a BMJ Online First paper this week.
Poverty is not strongly linked to winter deaths in elderly British people, finds new research in this week's BMJ.
Starting in the mid-1850s, humans began living longer due, researchers believe, to improvements in living conditions, nutrition, income levels and medicine.But two USC gerontologists have found an invisible cause that could have important implications for modern-day health care.
Research links stroke damage to a rise in brain acidity following the oxygen depletion characteristic of the condition. The results may lead to new therapies designed to avert the often debilitating effects of stroke. A series of experiments implicated a recently described class of membrane ion channels to the influx of calcium in nerve cells starved of oxygen and subjected to acidic conditions. That calcium overload sets off a cascade of events toxic to cells.
A University of Alberta researcher has discovered a potential breakthrough for premature ejaculation--the most common sexual dysfunction in men--with a drug usually used to treat bi-polar or anxiety disorder.
Cancer researchers have long suggested that new targeted drugs may work best when paired with other therapies. In a new study published today in Cancer Research, scientists have taken some of the first steps to demonstrate this synergy in mouse and cell line models. The findings show that two different drugs may work better in a "one-two punch," targeting a cancer development process in two types of cells.
This issue of the Journal of Neuroscience includes: Spontaneous firing in clock neurons and the who's who signal in electric fish.
Counselors were more successful in motivating smokers to quit when they explored the smokers' personal values, discussed their knowledge of the health risks, and supported patients as they tried to solve their problem, a University of Rochester study has found.
The increased use of CT from 1992 to 2002 for the imaging of facial trauma has actually decreased imaging costs by 22% per patient, say researchers from Massachusetts General Hospital in Boston.
A genetically engineered 'mighty mouse' is helping Medical College of Georgia researchers find the best way for young people to build bone and avoid osteoporosis.
By combining stem cell science with orthopedic surgery, a team of researchers at the University of British Columbia and Vancouver Coastal Health Research Institute aims to reduce the 10 per cent failure rate in hip replacements and make repeat replacements and other joint repairs obsolete within 10-15 years.
A newly completed picture of how fruitflies control their blood sugar will inform researchers and clinicians about the basics of metabolism and how it relates to disease. Eric Rulifson, PhD, Assistant Professor of Cell and Developmental Biology at the University of Pennsylvania School of Medicine, and colleague Seung Kim, PhD, from Stanford University, discovered an interconnected network of cells that tell the fly to take up or release sugar, as needed.
The search-and-rescue dogs deployed following the Sept. 11, 2001, terrorist attacks have not suffered either immediate or short-term effects from exposure to the disaster sites. For the last three years, University of Pennsylvania School of Veterinary Medicine researchers tracked the health of 97 of 212 identified dogs deployed at the 9/11 disaster sites. Neither the death rate nor the cancer rate among the deployed dogs is different from that of the control group.
Donald M. O'Rourke, M.D., Associate Professor of Neurosurgery at the University of Pennsylvania School of Medicine, and Gurpreet S. Kapoor, PhD, Research Associate in O'Rourke's laboratory, have discovered that two proteins sitting on the surface of cells are the interconnected switches for turning uncontrolled cell growth on or off in the brain and other tissues. These coupled proteins are the Epidermal Growth Factor Receptor (EGFR) and the Signal Regulatory Protein.1 (SIRP.1).
The September 15, 2004 Journal of Clinical Investigation Press Release contains links to PDFs of all papers and commentaries, contact information for all authors, and summaries of the following papers: Venn Diagram Tactics to Vet Complex Disease, Picking Prostanoids to Provide Protection, New Veins of Thought for Retinal Degeneration, No Compensation Without PDX-1, Become One: Beat as One, Pathways to Immunity.
