Watertown, MA—Scientists at Boston Biomedical Research Institute (BBRI) and the University of Pennsylvania have found that combining two chemicals, one of which is the green tea component EGCG, can prevent and destroy a variety of protein structures known as amyloids. Amyloids are the primary culprits in fatal brain disorders such as Alzheimer's, Huntington's, and Parkinson's diseases. Their study, published in the current issue of Nature Chemical Biology (December 2009), may ultimately contribute to future therapies for these diseases. "These findings are significant because it is the first time a combination of specific chemicals has successfully destroyed diverse forms of amyloids...

ST. LOUIS -- While too much amyloid beta protein in the brain is linked to the development of Alzheimer's disease, not enough of the protein in healthy brains can cause learning problems and forgetfulness, Saint Louis University scientists have found. The finding could lead to better medications to treat Alzheimer's disease, said John Morley, M.D., director of the division of geriatrics at Saint Louis University and the lead researcher on the study. "This research is very exciting because it causes us to look at amyloid beta protein in a different way," Morley said. "After 20 years of research, what we...

Inhibitors of HMG-CoA reductase (statins) are widely used medications for reduction of cholesterol levels. Statin use significantly reduces risk of cardiovascular disease but has also been associated with lower risk of other diseases and conditions, including dementia. However, some reports suggest that statins also have detrimental effects on the brain......Our data suggest that simvastatin and pravastatin differentially affect expression of genes involved in neurodegeneration and that statin-dependent gene expression regulation is cell type specific (excerpted)

A diagnostic compound that allows researchers to look into the brains of Alzheimer's patients will be used for the first time to gauge the effects of an experimental therapy for the disease. Called florbetaben, the diagnostic could also provide important insights into the role of beta amyloid, a protein that accumulates into plaques in the brains of patients with Alzheimer's disease and has been shown to be toxic to nerve cells. The compound is an 18F-radiolabelled tracer that binds specifically to deposits of beta amyloid, and can be measured using positron emission tomography (PET), a nuclear imaging technique which produces a three-dimensional image of...

You shouldn't stay up all night worrying about it, but a new study has found a connection between a lack of sleep and a biomolecule thought to be important in the development of Alzheimer's disease. In both humans and mice, levels of a peptide called amyloid-β rise during waking hours and decline during sleep, researchers have found. They also report that sleep-deprived mice are more prone to developing deposits of amyloid-β, called plaques, like those found in the brains of Alzheimer's patients. Although far from proven, the finding suggests that sleep disorders could be a risk factor for Alzheimer's. On...

The standard explanation for what causes Alzheimer's is known as the amyloid hypothesis, which posits that the disease results from of an accumulation of the peptide amyloid beta, the toxic protein fragments that deposit in the brain and become the sticky plaques that have defined Alzheimer's for more than 100 years. Billions of dollars are spent yearly targeting this toxic peptide — but what if this is the wrong target? What if the disease begins much earlier, fueled by a natural process? Reporting in the current edition of the journal Neurobiology of Aging, UCLA professor of psychiatry George Bartzokis argues...

WASHINGTON (AP) - More than 35 million people around the world are living with Alzheimer's disease or other types of dementia, says the most in-depth attempt yet to assess the brain-destroying illness—and it's an ominous forecast as the population grays. The new count is about 10 percent higher than what scientists had predicted just a few years ago, because earlier research underestimated Alzheimer's growing impact in developing countries. Barring a medical breakthrough, the World Alzheimer Report projects dementia will nearly double every 20 years. By 2050, it will affect a staggering 115.4 million people, the report concludes.

Two potentially key genes linked to the development of Alzheimer's disease have been uncovered by UK researchers. It is the first gene clue to the condition in 16 years and has prompted scientists to rethink their theories on how the disease develops. The genes were pinpointed in a study of 16,000 DNA samples and are known to be implicated in inflammation and cholesterol breakdown. It is hoped the Nature Genetics study will open the way for new treatments.

NHS Worcestershire ruled that Judith Roe, 74, did not qualify for NHS funding because her condition was a "social" rather than "health" problem, even though she was so ill she could not make a cup of tea and regularly left the stove on. She was forced to sell her £200,000 home to pay her £600-a-week nursing home fees, which would have been funded if she had been categorised correctly. Her son, Richard, 40, urged other families in a similar situation to fight for the care they are entitled to. He said: "The way the health trust behaved was scandalous. It...

U.S. life expectancy has risen to a new high, now standing at nearly 78 years, the government reported Wednesday. The increase is due mainly to falling death rates in almost all the leading causes of death. The average life expectancy for babies born in 2007 is nearly three months greater than for children born in 2006. The new U.S. data is a preliminary report based on about 90 percent of the death certificates collected in 2007. It comes from the National Center for Health Statistics, part of the Centers for Disease Control and Prevention. Life expectancy is the period a...

We previously compared Obamacare to the German Aktion T4, in which "life unworthy of living" was to be eliminated through denial of medical care or even palliatives such as Zyklon B. In fairness to the health care bill HR 3200, of which we downloaded a complete copy, the section on end of life counseling does not mandate or even encourage euthanasia. ...However, Ezekiel Emanuel (Rahm Emanuel's brother, with close ties to Barack Obama) is on written record as advocating denial of "discretionary" medical care to patients with dementia such as Alzheimer's Disease: a position entirely consistent with Germany's Aktion T4...

In experiments with lab mice especially bred to develop symptoms of Alzheimer's disease, University of South Florida (USF) researchers at the Florida Alzheimer's Disease Research Center ADRC gave the aged animals the equivalent of the caffeine in five cups of coffee a day. The results? Their severe memory impairment was reversed. This study, along with other AD research by the same group of scientists, was just published in the Journal of Alzheimer's Disease. Both studies show that caffeine significantly decreased abnormal levels of beta amyloid (the protein linked to AD) in both the brains and blood of lab rodents who...

Early research findings may lead to new treatments for the diseaseUCLA scientists and colleagues from UC Riverside and the Human BioMolecular Research Institute have found that a form of vitamin D, together with a chemical found in turmeric spice called curcumin, may help stimulate the immune system to clear the brain of amyloid beta, which forms the plaques considered the hallmark of Alzheimer's disease. The early research findings, which appear in the July issue of the Journal of Alzheimer's Disease, may lead to new approaches in preventing and treating Alzheimer's by utilizing the property of vitamin D3 — a form...

The Republican chief judge of the Richmond-based federal appeals court has retired suddenly because of illness, giving President Obama another opening to fill on what was once considered the nation's most conservative appellate court. Karen Williams of South Carolina, the first female chief judge on the U.S. Court of Appeals for the 4th Circuit, stepped down this week shortly after learning that she was in the early stages of Alzheimer's disease, according to her family. Alzheimer's, for which there is no cure, can cause mental deterioration and memory loss. Williams is 57 years old. The 4th Circuit, an influential voice...

ScienceDaily (Aug. 18, 2008) — A new study conducted by researchers at Children's Hospital & Research Center Oakland shows that a century-old drug, methylene blue, may be able to slow or even cure Alzheimer's and Parkinson's disease. Used at a very low concentration – about the equivalent of a few raindrops in four Olympic-sized swimming pools of water – the drug slows cellular aging and enhances mitochondrial function, potentially allowing those with the diseases to live longer, healthier lives. A paper on the methylene blue study, conducted by Hani Atamna, PhD, and a his team at Children's, was published in...

Scientists have uncovered powerful evidence that caffeine not only helps to stave off the disease but can treat it. They hope soon to follow up the initial results from animal experiments with human patient trials. US neuroscientist Dr Gary Arendash, who led the research, said: "The new findings provide evidence that caffeine could be a viable 'treatment' for established Alzheimer's disease, and not simply a protective strategy. "That's important because caffeine is a safe drug for most people. It easily enters the brain, and it appears to directly affect the disease process." A key aspect of Alzheimer's is sticky clumps...

Drinking five cups of coffee a day could reverse memory problems seen in Alzheimer's disease, US scientists say. The Florida research, carried out on mice, also suggested caffeine hampered the production of the protein plaques which are the hallmark of the disease. Previous research has also suggested a protective effect from caffeine.

The...

Scientists have discovered how Alzheimer's spreads from one area of the brain to another, paving the way for possible new treatments. Using mice, research found that healthy rodents injected with brain tissue from affected animals went on to develop the same defect themselves. Tau tangles, one of two protein abnormalities found in Alzheimer's patients, were seen to spread through the brains of the injected mice. In Alzheimer's tau tangles form inside nerve cells, first destroying cells critical to memory, before then going on to damage other parts of the brain. Reporting in the journal Nature Cell Biology, the scientists from...

Canadian scientists have been inspired by analytical chemistry to attack Alzheimer's disease from all sides. Chris Orvig from the University of British Columbia, Vancouver, and colleagues made multifunctional compounds to target amyloid plaque formation, a possible cause of Alzheimer's disease. Amyloid plaques are protein clusters with metal ions that accumulate between neurons in Alzheimer's patients' brains. Orvig designed his compounds to combat the protein misfolding and metal-peptide interactions involved in amyloid plaque production as well as the oxidative stress that occurs (a condition that damages cells, caused by excess free radicals). 'We aren't 100 per cent sure about the order...

UK and Dutch scientists have mimicked an ancient Chinese culinary technique of preserving eggs to study how proteins cause disease. Erika Eiser from the University of Cambridge and colleagues looked at how proteins in egg whites altered during this preservation process. The Chinese method involves wrapping raw eggs in an alkaline paste of lime, clay, salt, ash and tea and storing these so-called century eggs for several months. Eiser modified the method by incubating a boiled egg in a strong alkaline sodium hydroxide-salt solution for up to 26 days. Hard boiled egg whites become a transparent gel in an alkaline...

Keeping the brain active by working later in life may be an effective way to ward off Alzheimer's disease, research suggests. Researchers analysed data from 1,320 dementia patients, including 382 men. They found that for the men, continuing to work late in life helped keep the brain sharp enough to delay dementia taking hold. The study was carried out by the Institute of Psychiatry at King's College London. It features in the International Journal of Geriatric Psychiatry. Around 700,000 people in the UK currently have dementia and experts have estimated that by 2051, the number could stand at 1.7m. It...

Researchers at the University of California, San Francisco (UCSF), and the University of Pittsburgh have developed the first screening tool that can help predict whether elderly patients are at low, moderate or high risk of developing dementia.

A new test can accurately detect Alzheimer's disease in its earliest stages, before dementia symptoms surface and widespread damage occurs, U.S. researchers said on Monday. The test, which measures proteins in spinal fluid that can point to Alzheimer's, was 87 percent accurate at predicting which patients with early memory problems and other symptoms of cognitive impairment would eventually be diagnosed with Alzheimer's, they said. "With this test, we can reliably detect and track the progression of Alzheimer's disease," said Leslie Shaw of the University of Pennsylvania School of Medicine, whose study appears in the Annals of Neurology. Such tests, which...

Non-infectious form of prion protein could cause brain degeneration. Prion proteins may react with amyloid-(beta) peptides inside the brain cells of Alzheimer's patients.Thomas Deerinck NCMIR/Science Photo Library Non-infectious prion proteins found in the brain may contribute to Alzheimer's disease, researchers have found. The surprising new results, reported this week in Nature1, show that normal prion proteins produced naturally in the brain interact with the amyloid-(beta) peptides that are hallmarks of Alzheimer's disease. Blocking this interaction in preparations made from mouse brains halted some neurological defects caused by the accumulation of amyloid-(beta) peptide. It was previously thought that only infectious prion...

... We present a novel computational approach for describing the formation of oligomeric assemblies at experimental concentrations and timescales. We propose an extension to the Markovian state model approach, where one includes low concentration oligomeric states analytically. This allows simulation on long timescales (seconds timescale) and at arbitrarily low concentrations (e.g., the micromolar concentrations found in experiments), while still using an all-atom model for protein and solvent. As a proof of concept, we apply this methodology to the oligomerization of an Abeta peptide fragment (Abeta 21–43). Abeta oligomers are now widely recognized as the primary neurotoxic structures leading to Alzheimer's...
