At the synapse: Gene may shed light on neurological disorders
In our brains, where millions of signals move across a network of neurons like runners in a relay race, all the critical baton passes take place at synapses.   view more (2008-05-23)

HIV in the nervous system - still a cause for concern?
HIV infection can be controlled with antiretroviral drugs, but it cannot be wiped out. New evidence suggests that low levels of HIV may still lead to long-term brain damage and dementia, scientists heard today (Tuesday 09 April 2002) at the spring meeting of the Society for General Microbiology at... view more (2002-04-02)

Unravelling new complexity in the genome
A major surprise emerging from genome sequencing projects is that humans have a comparable number of protein-coding genes as significantly less complex organisms such as the minute nematode worm Caenorhabditis elegans.   view more (2007-08-14)

UCSF study finds nerve regeneration is possible in spinal cord injuries
A team of scientists at UCSF has made a critical discovery that may help in the development of techniques to promote functional recovery after a spinal cord injury.   view more (2005-12-02)

Multiple organ failure and malignant tumors main causes of death in ICU and hospital
Multiple organ failure is the main cause of death in intensive care units. A study published today in the journal Critical Care shows that the main risk factors for death in the intensive care unit are central nervous system failure and cardiovascular failure, and the most frequent cause of death... view more (2006-11-03)

Chemotherapy can be more toxic to brain cells than to cancer cells and may cause brain damage
Drugs used to treat cancer may damage normal, healthy brain cells more than the cancer cells they are meant to target.   view more (2006-11-30)

In the war against diseases, nerve cells need their armor
In a new study, researchers at the Montreal Neurological Institute (MNI), McGill University, and the Université de Montréal have discovered an essential mechanism for the maintenance of the normal structure of myelin, the protective covering that insulates and supports nerve cells... view more (2008-11-13)

Over-the-Counter Arthritis Drug Glucosamine Might Also Help Against MS
Glucosamine, the over-the counter natural product that has been touted to help with joint and cartilage problems associated with arthritis, may also provide some relief to individuals with multiple sclerosis (MS), a degenerative, nervous system disease with no known cure.   view more (2005-11-29)

Striking the right balance between excitation and inhibition
Neurons in the brain and spinal cord come in two flavors, excitatory neurons that transmit and amplify signals, and inhibitory neurons that inhibit and refine those signals.   view more (2006-05-31)

MS patients have higher spinal fluid levels of suspicious immune molecule
A protein that helps keep immune cells quiet is more abundant in the spinal fluid of patients with multiple sclerosis (MS), further boosting suspicion that the protein, TREM-2, may be an important contributor to the disease.   view more (2008-09-30)

Cooling analgesia harnessed to relieve chronic pain
By experimentally activating a special protein involved in mediating sensations of coolness, researchers have made a breakthrough in understanding how the body's nervous system can be stimulated to relieve chronic pain.   view more (2006-08-22)

Bees go 'off-color' when they are sickly
Bumble-bees go 'off colour' and can't remember which flowers have the most nectar when they are feeling under the weather, a new study from the University of Leicester reveals.   view more (2008-07-16)

RNA splicing occurs in nerve-cell dendrites
Researchers at the University of Pennsylvania School of Medicine have discovered that nerve-cell dendrites have the capacity to splice messenger RNA (pre-mRNA), a process once believed to only take place in the nucleus of cells.   view more (2005-11-08)

Powerful new tool for studying brain development
Scientists at St. Jude Children's Research Hospital have given investigators around the world free access to a powerful tool for studying brain development.   view more (2006-03-28)

Dangerous Interaction Between The Antidepressant Fluvoxamine (Fevarin, Faverin, Luvox) And The Muscle Relaxant Tizanidine (Sirdalud, Zanaflex)
Researchers from Finland have found that the antidepressant drug fluvoxamine (brand names Fevarin, Faverin, Luvox etc.) drastically increases the concentrations of tizanidine (Sirdalud, Zanaflex) in blood. Concomitant use of fluvoxamine and tizanidine results in severe and prolonged decrease in... view more (2004-04-06)

Adult crime linked to childhood anxiety
Being nervous, socially isolated, anxious or neurotic during childhood protects young men from becoming criminal offenders until they enter adulthood, but the protective effect seems to wear off after the age of 21.   view more (2008-11-04)

Study connects obesity with nervous system
A discovery by Queen's biologists and their students sheds new light on the genetic roots of obesity - a condition that is increasing dramatically in North America and has been linked to heart disease, diabetes and some forms of cancer.   view more (2008-01-24)

Can moths or butterflies remember what they learned as caterpillars?
Butterflies and moths are well known for their striking metamorphosis from crawling caterpillars to winged adults. In light of this radical change, not just in body form, but also in lifestyle, diet and dependence on particular sensory cues, it would seem unlikely that learned associations or... view more (2008-03-05)

Women recover muscle strength more slowly than men
Women's muscles may require longer, more intensive rehabilitation after bed rest and cast immobilization, as reported today by the Institute for Neuromusculoskeletal Research at the Ohio University College of Osteopathic Medicine (OU-COM).   view more (2008-09-26)

New research shows how chronic stress worsens neurodegenerative disease course
The evidence is accumulating on how bad stress is for health. Chronic stress can intensify inflammation and increase a person's risk for developing central nervous system infections, neurodegenerative diseases, like multiple sclerosis (MS), and other inflammatory diseases.   view more (2007-08-20)

Researchers discover gene essencial to cerebellum formation
A study published this week in the scientific journal PNAS provides new information on the origin of different cells in the cerebellum, an important component of the central nervous system found in all vertebrates, including humans, and the part of the brain that controls movement.   view more (2007-03-07)

New targeted treatment for brain tumors shows promise in pre-clinical models
Monoclonal antibody targets key tumor growth factor; Successfully causes brain tumor regression and improves animal survival.   view more (2006-02-15)

Childhood cancer survivors treated with radiation face increased risk of tumors later in life
University of Minnesota cancer researchers found that children who received radiation treatment for cancer face an increased risk for brain and spinal column tumors later in life.   view more (2006-11-02)

Further legitimization of fibromyalgia as a true medical condition
Fibromyalgia, a chronic, widespread pain in muscles and soft tissues accompanied by fatigue, is a fairly common condition that does not manifest any structural damage in an organ.   view more (2007-06-26)

Pregnancy hormone increases nerve cells' insulation, restores damage
A hormone produced during pregnancy spontaneously increases myelin, which enhances signaling within the nervous system, and helps repair damage in the brain and spinal cord.   view more (2007-02-21)
