Discovery provides additional key insights into the biology of Multiple Sclerosis

A Griffith University medical scientist is part of an international team which has made a key discovery in the effort to find the cause and cure of Multiple Sclerosis.

Understanding protein evolution

Highlighting an important but unexplored area of evolution, scientists at The Scripps Research Institute have found evidence that, over hundreds of millions of years, an essential protein has evolved chiefly by changing how it moves, rather than by changing its basic molecular structure. The work has implications not only for the understanding of protein evolution, but also for the design of antibiotics and other drugs that target the protein in question.

Biology of tumour more important than primary site, say researchers

Identifying the molecular profile of a tumour where the primary site is unknown is crucial to the choice of treatment, the 2013 European Cancer Congress, will hear on Monday.

Scientists discover two new compounds that could help treat CF patients having common mutation

Cystic fibrosis is a lethal genetic disorder that in France affects one child per 4,500 births. An international team led by scientists at the Institut Fédératif de Recherche Necker-Enfants Malades (CNRS/Inserm/Université Paris Descartes), led by Aleksander Edelman, has recently discovered two new compounds that could be used to treat patients carrying the most common mutation.

Study suggests relationship between smoking history, response to inhibiting PD-L1/PD-1 pathway

New results from a trial of an antibody that helps the immune system to recognise and attack cancer cells have shown particularly encouraging responses in patients who are smokers or former smokers.

Oxytocin helps humans accept others, study finds

Oxytocin - often referred to as the 'love hormone' because of its ability to promote mother-infant attachment and romantic bonding in adults - could also make us more accepting of other people, as found in new research, "Oxytocin Sharpens Self-other Perceptual Boundary," by Neuropsychoanalysis Foundation research grantee Valentina Colonnello Ph.D. published online today in Psychoneuroendocrinology.

Novel nuclear MRI technique delivers roughly 10-nanometer spatial resolution

A team from the University of Illinois at Urbana-Champaign and Northwestern University has devised a novel nuclear magnetic resonance imaging technique that delivers a roughly 10-nanometer spatial resolution.

Biochemists discover promising vitamin D-based treatment that can halt MS

A diagnosis of multiple sclerosis is a hard lot. Patients typically get the diagnosis around age 30 after experiencing a series of neurological problems such as blurry vision, wobbly gait or a numb foot. From there, this neurodegenerative disease follows an unforgiving course.

Study provides new insights into type 1 diabetes pathology

Joslin researchers have identified immune cells that promote growth of beta cells in type 1 diabetes. This study provides further evidence of a changed role for immune cells in type 1 diabetes pathology. The study appears online today and will also appear in the January issue of Diabetes.

Researchers discover severe health consequences of folic acid deficiency

Researchers from the universities of Calgary and Cambridge, UK, have discovered that a mutation in a gene necessary for the metabolism of folic acid not only impacts immediate offspring but can also have detrimental health effects, such as spina bifida and heart abnormalities, on subsequent generations.

Scientists identify 140 regions of genetic code believed to contain undiscovered cancer genes

Scanning the DNA of nearly 5,000 tumor samples, a team led by scientists at Dana-Farber Cancer Institute and the Broad Institute has identified 140 regions of scrambled genetic code believed to contain many undiscovered cancer genes.

c-Fos oncogene cab be important target for understanding and treatment of cancer

The c-Fos oncogene has traditionally been linked to cellular activities related to cancer, such as cell division, differentiation-conversion from one cell type to another-or survival. Any alteration of these activities can set off the development of tumours, which has made c-Fos an important target for the understanding and treatment of cancer.

Research opens up possibility for new treatment approaches for motor neurone disease

New research from the University of Sheffield could offer solutions into slowing down the progression of motor neurone disease.

Extensive Combinatorial Refinement process creates computerized molecular models more automatically

It's difficult and time-consuming to produce accurate computer models of molecules, primarily because traditional modeling methods are limited in their ability to handle alternative molecular shapes and, consequently, are subject to multiple errors.

Research findings could help improve treatment for patients with chronic dizziness

Scientists have discovered differences in the brain structure of ballet dancers that may help them avoid feeling dizzy when they perform pirouettes.

Sister stem cells display considerable differences despite having identical DNA

Scientists have used a brand new technique for examining individual stem cells to uncover dramatic differences in the gene expression levels - which genes are turned 'up' or 'down'- between apparently identical 'sister' pairs.

Dynamics of the mitochondria linked to obesity

Becoming obese or remaining lean can depend on the dynamics of the mitochondria, the body's energy-producing "battery," according to two new studies by Yale School of Medicine researchers featured as the cover story in the Sept. 26 issue of the journal Cell.

Length of telomere may help determine prostate cancer patient's prognosis

Like the plastic caps at the end of shoelaces, telomeres protect — in their case — the interior-gene containing parts of chromosomes that carry a cell's instructional material. Cancer cells are known to have short telomeres, but just how short they are from cancer cell to cancer cell may be a determining factor in a prostate cancer patient's prognosis, according to a study led by Johns Hopkins scientists.

Researchers make progress in understanding traits and processes that influence fertilization success

Female promiscuity-something that occurs in a majority of species, including humans-results in the ejaculates from two or more males overlapping within her reproductive tract. When this happens, sperm compete for fertilization of the female's eggs. In addition, the female has the opportunity to bias fertilization of her eggs in favor of one male's sperm over others.
