Common antibiotic called minocycline may slow or prevent diabetic retinopathy

The team found that minocycline, often used to treat acne, limits by about 50 percent the retinal damage caused by microglia. Microglia are cells that act as the "cleanup crew" for the Central Nervous System (CNS).

Magnetic stimulation treatment for depression

Barbara Baas ran away from home and tried to kill herself as a teenager. As an adult, she has tried more than 15 varieties of antidepressants. But, thanks to a new weapon, she has finally reached a truce in a 45-year battle.

Discovery reveals how stem cells can be used to help repair acute spinal cord damage

A treatment derived from human embryonic stem cells improves mobility in rats with spinal cord injuries, providing the first physical evidence that the therapeutic use of these cells can help restore motor skills lost from acute spinal cord tissue damage.

"Anxiety Gene" linked to depression, makes the body out of tune

U.S. scientists in viewing the human body as a well-tuned orchestra, say that think they may have found a discordant note in the form of a gene which appears to increase the likelihood of some people developing anxiety and depression.

Suspect gene may increase susceptibility to anxiety and depression

People with the depression-linked gene variant showed less gray matter and weaker connections in the mood-regulating circuit. How well the circuit was connected accounted for nearly 30 percent of their anxious temperament

Mosaic Analysis with Double Markers (MADM) - A powerful new tool to study diseases and genetics

A powerful laboratory technique used by fruit fly geneticists for more than a decade is now available to scientists studying genes and diseases in mice.

Does clinical depression bring about chronic pain? Or does pain lead to depression?

Does clinical depression bring about chronic pain? Or does pain lead to depression? Because these two conditions frequently co-exist--30 to 54 percent of patients with major depressive disorder also suffer persistent physical pain--there has been much speculation about whether one causes the other or whether a common underlying factor provokes both. Results of studies into the precise nature of this relationship, however, have been inconsistent.

The humble snail is helping scientists explore ways of treating memory loss in humans

Drug manufacturers are looking at ways to create a "Viagra for the brain", which could alleviate memory loss, one of the distressing symptoms of diseases such as Alzheimer's. Work carried out by Dr George Kemenes, Senior Fellow in the Department of Biology and Environmental Science at the University of Sussex, will hopefully help to show how such drugs could work.

Glucose byproduct prevents brain damage after diabetic coma

A natural, non-toxic byproduct of glucose may prevent brain cell death and cognitive impairment in diabetics following an episode of severely low blood sugar, according to researchers at the San Francisco VA Medical Center (SFVAMC).

Potential for brain stem cells to be used to cure diabetes

Promising new research by US scientists has shown the potential for brain stem cells to be used to cure diabetes. The work by Stanford University researchers, though not yet ready to be tested on human patients, has shown promising results in animals.

Clues about the causes of dementia in Huntington's disease

Scientists at Melbourne's Howard Florey Institute have uncovered a clue about the causes of dementia in Huntington's disease, one of the disease's symptoms, by showing that mice susceptible to Huntington's disease have problems with learning and memory before the diseases' typical movement problems appear.

Researchers zero in on sleep gene

Zeroing in on the core cellular mechanisms of sleep, researchers at University of Wisconsin Medical School have identified for the first time a single gene mutation that has a powerful effect on the amount of time fruit flies sleep.

Moderate alcohol consumption enhances the formation of new nerve cells

Moderate alcohol consumption over a relatively long period of time can enhance the formation of new nerve cells in the adult brain. The new cells could prove important in the development of alcohol dependency and other long-term effects of alcohol on the brain. The findings are published by Karolinska Institutet.

Important new finding about the brain and its stem cells

A family's bravery and generosity in the face of their son's death three years ago has enabled researchers to make an important new finding about the brain and its stem cells.

Genetic variation linked to alcohol dependence

The same gene that accounts for part of a genetic risk for developing alcoholism in a U.S. population is found in a Russian population, according to a published study by a Yale School of Medicine researcher.

Gene may boost schizophrenia risk

Clues about how a suspect version of a gene may slightly increase risk for schizophrenia are emerging from a brain imaging study by the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH). The gene variant produced a telltale pattern of activity linked to production of a key brain messenger chemical.

Why people get drowsy and fall asleep, and how caffeine blocks that process

When cells in a certain part of the brain become overworked, a compound in the brain kicks in, telling them to shut down. This causes people to become drowsy and fall asleep. Alter that natural process by adding coffee or tea, and the brain compound – called adenosine – is blocked, and people stay awake.

Louder neurons drown out their quieter neighbors

As the brain develops, neurons reach out helter-skelter to form new connections, only a small number of which take hold. How the brain chooses which connections to keep and which to prune back appears to be governed by which branches have the most electrical activity-a finding that could help to explain how early experiences guide brain development.

Insights could yield new approaches to nerve regeneration

Nervous system development requires billions of neurons to migrate to the appropriate locations in the brain and grow nerve fibers (axons) that connect to other nerve cells in an intricate network.
