Gene find sheds light on motor neuron diseases like amyotrophic lateral sclerosis

Scientists have identified a gene in mice that plays a central role in the proper development of one of the nerve cells that goes bad in amyotrophic lateral sclerosis, or Lou Gehrig's disease, and some other diseases that affect our motor neurons.

Genes that control cell death may play role in age-related hearing loss

Several genes that play a role in how our body's cells normally auto-destruct may play a role in age-related hearing loss, according to research published online in the journal Apoptosis - a journal devoted to the topic of cell suicide, or programmed cell death.

Discovery of earliest known cases of human tuberculosis in Neolithic village

The discovery of the earliest known cases of human tuberculosis (TB) in bones found submerged off the coast of Israel shows that the disease is 3000 years older than previously thought. Direct examination of this ancient DNA confirms the latest theory that bovine TB evolved later than human TB.

Testicles may be a source of stem cells

A team of researchers from Britain and Germany have found that a man's testicles may be a source of stem cells.

Injections of N-acetyl cysteine may help 'chemobrain'

Cancer patients have complained for years about the mental fog known as chemobrain. Now in animal studies at West Virginia University, researchers have discovered that injections of N-acetyl cysteine (NAC), an antioxidant, can prevent the memory loss that breast cancer chemotherapy drugs sometimes induce.

Vitamin B deficiency may cause vascular cognitive impairment

A deficiency of B-vitamins may cause vascular cognitive impairment, according to a new study. Researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University used an experimental model to examine the metabolic, cognitive, and microvascular effects of dietary B-vitamin deficiency.

Computed tomography provides anatomy - we need ischemia!

Cardiac computed tomography has revolutionized cardiac imaging in recent years by providing exquisitely detailed cardiac anatomy, including, but not limited to, coronary anatomy.

Childhood pets may make adults snorers

New research into why people snore has found that the roots of the problem possibly go back to a person's childhood.

New technique offers hope for stroke sufferers

If a stroke patient doesn't get treatment within approximately the first three hours of symptoms, there's not much doctors can do to limit damage to the brain.

Novel imaging reagents and technology that non-invasively locates, quantifies specific cells in the body

Magnetic resonance imaging (MRI) isn't just for capturing detailed images of the body's anatomy. Thanks to novel imaging reagents and technology developed by Carnegie Mellon University scientist Eric Ahrens, MRI can be used to visualize - with "exquisite" specificity - cell populations of interest in the living body. The ability to non-invasively locate and track cells, such as immune cells, will greatly aid the study and treatment of cancer, inflammation, and autoimmune diseases, as well as provide a tool for advancing clinical translation of the emerging field of cellular regenerative medicine, by tracking stem cells for example.

Scientists stop age-related decline in an entire organ

As people age, their cells become less efficient at getting rid of damaged protein - resulting in a buildup of toxic material that is especially pronounced in Alzheimer's, Parkinson's disease, and other neurodegenerative disorders.

Bristol academic takes viewers on a second tour of the human body

Dr Alice Roberts, Senior Teaching Fellow at Bristol University's Department of Anatomy, returns to television tonight for the second series of Don't Die Young, in which, through her presentation of the workings of the human body, she demonstrates how we can all be happier, healthier and live longer. To show how this is possible, she puts her own body through a series of tests and scans - including dropping it from the ceiling of the Birmingham Symphony Hall.

The brain under pressure: Bristol Neuroscience attracts BBSRC grant

The Biotechnology and Biological Sciences Research Council (BBSRC) has awarded a grant of over £0.5 million to groups in the Laboratories for Integrative Neuroscience and Endocrinology and the MRC Centre for Synaptic Plasticity (project leader, Professor Kei Cho). The funding will support research into how brain cells maintain their performance, and create memories, during periods of acute stress.

PET-CT scanners detect secondary head and neck cancers

For patients with head and neck cancer, accurately determining how advanced the cancer is and detecting secondary cancers usually means undergoing numerous tests - until now.

Scientists map anatomy of a membrane protein

In an Australian first, scientists at Sydney's Centenary Institute have mapped the anatomy of a membrane protein. This exciting discovery has the potential to turn the way we discover new drugs on its head and reduce the development time for new treatments.

The good and bad side of dopamine

The chemical dopamine induces both desire and dread, according to new animal research in the July 9 issue of The Journal of Neuroscience. Although dopamine is well known to motivate animals and people to seek positive rewards, the study indicates that it also can promote negative feelings like fear.

93-year old man with life threatening aneurysm treated using new fenestrated endograft stent

In a New York City metro-area first, a 93-year-old Bronx man underwent implantation of a new stent graft at NewYork-Presbyterian Hospital, the only center on the Eastern Seaboard with access to this investigational device. The new stent graft was implanted under an FDA-approved clinical trial protocol.

New comprehensive map of brain connections

An international team of researchers has created the first complete high-resolution map of how millions of neural fibers in the human cerebral cortex -- the outer layer of the brain responsible for higher level thinking -- connect and communicate. Their groundbreaking work identified a single network core, or hub, that may be key to the workings of both hemispheres of the brain.

Tongue-operated assistive technology lets persons with disabilities operate powered wheelchairs

A new assistive technology developed by engineers at the Georgia Institute of Technology could help individuals with severe disabilities lead more independent lives.
