FA imaging, invented at U-M, measures metabolic stress in retina - serves as early warning of diabetes

A new vision screening device, already shown to give an early warning of eye disease, could give doctors and patients a head start on treating diabetes and its vision complications, a new study shows.

Does sleep help us change or clarify our mind?

When we have to make a difficult decision, or work through an idea, it's often best to 'sleep on it' and come back to it fresh the next day. Swiss scientists have discovered that sleep can have lasting consequences on brain function by stimulating new brain connections that strengthen the learning processes and directly influence our actions.

Brain switch provides clues to drug addiction

In the quest to find the biological route of drug addiction, research at Cambridge University, UK, is revealing what makes some people more vulnerable than others. Speaking at Europe's major neuroscience conference in Geneva, Professor Barry Everitt described what they now believe causes the switch from occasional, 'recreational' use to a compulsive habit.

Optimism is good for heart health, at least among men, a new study shows

University of Rochester Medical Center researcher Robert Gramling, M.D., D.Sc., found that men who believed they were at lower-than-average risk for cardiovascular disease actually experienced a three times lower incidence of death from heart attacks and strokes.

Researchers locate and image prostate cancer as it spreads to lymph nodes

Using an engineered common cold virus, UCLA researchers delivered a genetic payload to prostate cancer cells that allowed them, using Positron Emission Tomography (PET), to locate the diseased cells as they spread to the lymph nodes, the first place prostate cancer goes before invading other organs.

Researchers identify brain cells related to fear - paves way for more effective PTSD treatments

The National Institute of Mental Health estimates that in any given year, about 40 million adults (18 or older) will suffer from some form of anxiety disorder, including debilitating conditions such as phobias, panic disorders and post-traumatic stress disorder (PTSD). It is estimated that nearly 15 percent of U.S. soldiers returning from Iraq and Afghanistan develop PTSD, underscoring the urgency to develop better treatment strategies for anxiety disorders.

Advances in RNA research

RNA, the transporter of genetic information within the cell, has emerged from the shadow of DNA to become one of the hottest research areas of molecular biology, with implications for many diseases as well as understanding of evolution. But the field is complex, requiring access to the latest equipment and techniques of imaging, gene expression analysis and bioinformatics, as well as cross-pollination between multiple scientific disciplines.

Gene silencer and quantum dots reduce protein production to a whisper

More than 15 years ago, scientists discovered a way to stop a particular gene in its tracks. The Nobel Prize-winning finding holds tantalizing promise for medical science, but so far it has been difficult to apply the technique, known as RNA interference, in living cells.

Holey nanoparticles create new tumor imaging and therapeutic agent

Using a polymer that has both water-soluble and water-insoluble regions, a team of investigators from the Siteman Center of Cancer Nanotechnology Excellence has created a nanoparticle shaped like a bialy, a close relative of the bagel. Combining this nanoparticle with manganese, a metal that boosts magnetic resonance imaging signals, and an antibody that targets blood vessels, the investigators then created a new type of imaging agent that also has the potential to deliver drugs to tumors.

Nanocantilevers image nanoparticles in cells

Borrowing from a Nobel Prize-winning technique credited with starting the nanotechnology revolution, a team of researchers from Oak Ridge National Laboratory (ORNL) and Northwestern University's Nanomaterials for Cancer Diagnostics and Therapeutics has developed a method for imaging nanoparticles inside of cells.

Small portable MRI scanners developed

The term "MRI scan" brings to mind the gigantic, expensive machines that are installed in hospitals. But research scientists have now developed small portable MRI scanners that perform their services in the field: for instance to examine ice cores.

New 3-D object recognition and image processing technology to detect cancer

Technology which will make it possible to semi-automate the process for detecting cancerous tumours more precisely is being developed by academics at the University of Hertfordshire.

Researchers detail types of genes necessary for brain

Researchers from Harvard Medical School and Brandeis University have successfully completed a full-genome RNAi screen in neurons, showing what types of genes are necessary for brain development. Details of the screen and its novel methodology are published July 4th in the open-access journal PLoS Genetics.

U-M study to look at effects of chemotherapy on brain function of breast cancer survivors

While Maria Lyzen was being treated for breast cancer, she found she couldn't concentrate or decipher information, and just functioning day-to-day at home was difficult.

A noisy brain is a healthy brain

Canadian scientists have shown that a noisy brain is a healthy brain. "Brain noise" is a term that has been used by neuroscientists to describe random brain activity that is not important to mental function.

Report says cancer clinicians should understand and consider the economic impact of new interventions

Cancer clinicians should understand and consider the economic impact of new interventions, which often have substantial costs, according to a report appearing in the July/August issue of CA: A Cancer Journal for Clinicians, a peer-reviewed journal of the American Cancer Society.
