Evidence links cellular iron deficiency to restless legs syndrome

Iron-deficient cells in the brain are mixing up central nervous system signals to the legs and arms causing the irresistible urges to move and creepy-crawly sensations that characterize restless legs syndrome (RLS), a Penn State College of Medicine study reports.

Scientists are testing the effectiveness of a new type of flu vaccine

The experimental vaccine instead relies on a cell line drawn from insects known as silk moths, which are better known for their role as pests attacking crops such as corn, cotton, barley and alfalfa.

Researchers have identified a protein in the brain that halts the progression of Alzheimer's

Researchers have identified a protein in the brain that halts the progression of Alzheimer's disease in human brain tissue. The protein, known as "transthyretin," protects brain cells from gradual deterioration by blocking another toxic protein that contributes to the disease process.

New oral vaccine treatment is effective in reducing Alzheimer's disease pathology

Alzheimer's disease is characterized by progressive loss of cognitive function due to amyloid-beta (Aß) deposits in the central nervous system. If these deposits could be stopped or slowed, Alzheimer's disease might become more manageable.

Potential new treatment strategy against metastatic cancer cells

A team of scientists at The Scripps Research Institute has identified a potential treatment strategy against metastatic cancer cells that has never been tried before.

Allopurinol, a common gout drug may also offer some protection against colorectal cancer

A commonly prescribed drug used to treat gout may also offer some protection against colorectal cancer, according to a new study from researchers at the University of Michigan and in Israel.

A single change in a person’s DNA can contribute to a range of life-shortening risk factors

A woman with hypertension, low magnesium levels, and a cooperative family allowed scientists to pinpoint the mutation, which affects the genes of the mitochondria — the energy-producing power plants of the cell that are passed from mother to offspring.

Breakthrough discovery in treating narrowed arteries

A breakthrough discovery by Heart and Stroke Foundation researcher Dr. Michael Kutryk that harnesses the body’s own natural defenses to fight narrowing of the arteries has been recognized as “a glimpse into the future” and “potentially one of the biggest advances in cardiology to date”.

As the 2004 Presidential election nears, the issue of human cloning and embryonic stem cell research is under intense debate

The United Nations, headed by Secretary General Kofi Annan is currently debating two proposals: one from Costa Rica and supported by the U.S. and sixty-two other countries that would ban all human cloning, and another from Belgium and twenty-one other countries that would allow cloning of human embryos but not their transfer to a womb.

Findings could lead to improvements in the next generation of implantable cardioverter defibrillators

For people who suffer from a rapid heartbeat condition called tachycardia, an implanted device can usually nudge the racing blood pump back into a normal rhythm by applying electrical pulses to the heart.

Australian platypus research has implications for understanding the evolution of human sex determination

The mystery surrounding sex determination of the unique Australian platypus has yielded a surprising secret: it has 10 sex chromosomes.

High levels of a protein called LRP6 can make cancer cells more aggressive

The protein's ability to enhance tumor development suggests that the gene that codes for LRP6 is an oncogene--a gene that contributes to tumor development when overactivated.

New understanding of how poxviruses jump from species to species

A Canadian study conducted at Robarts Research Institute sheds new light on how poxviruses can jump from species to species -- and will lead to further exploration of another potential candidate in the emerging field of “oncolytic viruses” to fight cancer.

Calorie restriction prevents certain aging-related changes in the brain

Severe calorie restriction prevents certain aging-related changes in the brain, including the accumulation of free radicals and impairments in coordination and strength, according to a mouse study at Washington University School of Medicine in St. Louis.

Potential new protein marker for prognosis of breast and ovarian cancer

The researchers matched tumor samples to outcomes in about 100 patients diagnosed with either breast or ovarian cancer and found that a low level of Rab25 protein on a patient's cancer sample was associated with a better clinical outcome in both cancer types.
