New technique can detect small secondary brain tumours

Cancer Research UK scientists have developed a technique they believe could be used to detect tiny secondary tumours in the brain, a process that is currently impossible, according to research published in PNAS.

Defects in schizophrenia-risk genes and environmental stress lead to abnormal brain development

Working with genetically engineered mice and the genomes of thousands of people with schizophrenia, researchers at Johns Hopkins say they now better understand how both nature and nurture can affect one's risks for schizophrenia and abnormal brain development in general.

Intravenous immune globulin effective treatment for GBS, CIDP

Intravenous immune globulin (IVIg) is an effective treatment for certain disorders of the nerve and muscles, including Guillain-Barré syndrome (GBS) and a form of neuropathy called chronic inflammatory demyelinating polyneuropathy (CIDP), according to a guideline issued by the American Academy of Neurology.

Scientists create first full 3-D images of vitamin B12

In a paper published recently in the journal Nature, scientists from the University of Michigan Health System and the Massachusetts Institute of Technology report they have created the first full 3-D images of B12 and its partner molecules twisting and contorting as part of a crucial reaction called methyltransfer.

Nanoscale sensor can conduct individual DNA sequencing

Researchers have devised a nanoscale sensor to electronically read the sequence of a single DNA molecule, a technique that is fast and inexpensive and could make DNA sequencing widely available.

Study reveals how HSV-1 virus overcomes intrinsic host defenses

New biological research reveals how an invading virus hijacks a cell's workings by imitating a signaling marker to defeat the body's defenses. By manipulating cell signals, the virus destroys a defensive protein designed to inhibit it. This finding, from studies in human cell cultures, may represent a broader targeting strategy used by other viruses, and may lay the scientific groundwork for developing more effective treatments for infectious diseases.

Repeated stress triggers tau protein aggregates inside brain cells

Repeated stress triggers the production and accumulation of insoluble tau protein aggregates inside the brain cells of mice, say researchers at the University of California, San Diego School of Medicine in a new study published in the March 26 Online Early Edition of the Proceedings of the National Academy of Sciences.

Gene fault linked to flu risk for hospitalization: Study finds

Researchers have found a genetic flaw that may explain why some people get more ill with flu than others. The study was reported in the journal Nature this Sunday, where researchers said the variant of the IFITM3 gene was much more common in people hospitalized for flu than in the general population. It controls a malformed protein, which makes cells more susceptible to viral infection. Experts said those with the flaw could be given the flu jab, like other at-risk groups.

Study reveals mechanism by which AD may cause memory loss

Alzheimer's disease (AD) steals memory and ruins lives. Despite near-daily reports of promising new therapies, AD remains unchecked. Now a new study reveals the mechanism by which AD may cause memory loss, suggesting new therapies.

Synthetic pasta-like objects are major chemistry advances for regenerative medicine

Medicine's recipe for keeping older people active and functioning in their homes and workplaces - and healing younger people injured in catastrophic accidents - may include "noodle gels" and other lab-made invisible filaments that resemble uncooked spaghetti with nanoscale dimensions, a scientist said here today at the 243rd National Meeting & Exposition of the American Chemical Society (ACS).

Population-wide community and clinical prevention program reduces cardiovascular risk profile

A population-wide community and clinical prevention program involving 10,000 adults meaningfully reduced the cardiovascular (CV) risk profile among a substantial portion of the population as indicated by those participating in screenings. Findings also indicate the level of improvements differ by gender for specific cardiovascular risk factors.

Commensal bacteria may play an important role in influencing and controlling allergic inflammation

When poet Walt Whitman wrote that we "contain multitudes," he was speaking metaphorically, but he was correct in the literal sense. Every human being carries over 100 trillion individual bacterial cells within the intestine -- ten times more cells than comprise the body itself.

Previously unknown mechanism helps intestinal bacteria to affect formation of blood vessels

Researchers at the Sahlgrenska Academy at the University of Gothenburg, Sweden, have discovered a previously unknown mechanism which helps intestinal bacteria to affect the formation of blood vessels. The results, which are presented in Nature, may provide future treatments of intestinal diseases and obesity.

Breast implant materials may deter cancer cells from dwelling and thriving

One in eight women in the United States will develop breast cancer. Of those, many will undergo surgery to remove the tumor and will require some kind of breast reconstruction afterward, often involving implants. Cancer is an elusive target, though, and malignant cells return for as many as one-fifth of women originally diagnosed, according to the American Cancer Society.

New advance in ability to target and destroy certain cancer cells

An international team of scientists has announced a new advance in the ability to target and destroy certain cancer cells. A group led by the University of Leicester has shown that particular cancer cells are especially sensitive to a protein called p21. This protein usually forces normal and cancer cells to stop dividing but it was recently shown that in some cases it can also kill cancer cells.

Study reveals central role played by DBIRD protein complex in gene transcription

In a study published this week in the journal Nature, researchers at the University of Liège's GIGA Unit, together with English and German teams, reveal the central role played by a protein complex, unknown up to now, in gene transcription.

Strong link between telomere shortening and heart disease risk

No one really wants the short end of the stick, in this case the short end of a chromosome. Telomeres, which are DNA-protein complexes at the ends of chromosomes, can be thought of as protein "caps" that protect chromosomes from deteriorating and fusing with neighboring chromosomes.

Study validates Mitofusin 2 as possible target for treatment of diabetes mellitus

Researchers at the Institute for Research in Biomedicine (IRB Barcelona) have discovered that deficiency of a single protein, Mitofusin 2, in muscle and hepatic cells of mice is sufficient to cause tissues to become insensitive to insulin, thus producing an increase in blood glucose concentrations. These are the two most common conditions prior to development of diabetes type 2.

Cathepsin Z protein regulates metastasis of pancreatic cancer

Researchers at Queen Mary, University of London have identified a new protein that makes pancreatic cancer cells less 'sticky' and therefore less able to attach to and invade other tissue.

Insulin resistance occurs in the brains of people with Alzheimer's

Insulin resistance in the brain precedes and contributes to cognitive decline above and beyond other known causes of Alzheimer's disease, according to a new study by researchers from the Perelman School of Medicine at the University of Pennsylvania. Insulin is an important hormone in many bodily functions, including the health of brain cells.
