Molecule that starts DNA repairs also halts them

Repairing DNA breaks can save a cell's life - but shutting off the repair machinery can be just as critical. How cells accomplish this feat was unknown. However, new research by Johns Hopkins scientists, published in the Feb. 22 issue of Nature, suggests that shutting down the repair machinery relies heavily on the same molecule used to start repair in the first place.

Psychopaths’ brains differ from healthy non-offenders: Study confirms

Approximately half of male prisoners in England and Wales will meet diagnostic criteria for ASPD. The majority of such men are not true psychopaths (ASPD-P). They are characterized by emotional instability, impulsivity and high levels of mood and anxiety disorders. They typically use aggression in a reactive way in response to a perceived threat or sense of frustration.

Chemically altered proteins may be key to understanding memories

Having a fat head may not be a bad thing, according to new findings at The Johns Hopkins University. As reported in the February 9 issue of Neuron, researchers have made a significant discovery as to how adding fat molecules to proteins can influence the brain circuitry controlling cognitive function, including learning and memory.

'Good' cholesterol may not protect against coronary heart disease

A new study by Harvard School of Public Health (HSPH) researchers has found that a subclass of high-density lipoprotein (HDL) cholesterol, the so-called "good" cholesterol, may not protect against coronary heart disease (CHD) and in fact may be harmful.

People can take themselves from good to great

The sayings "variety is the spice of life" and "happiness isn't getting what you want, but wanting what you get" seem to have a psychological basis, according to a new study by an MU psychologist who identified two keys to becoming happier and staying that way.

Cellular-level images of the living eye

The same technology used by astronomers to obtain clear views of distant stars is now being used by optometrists to perform incredibly detailed examinations of the living eye.

Amakem presents key preclinical data on AMA0076 at ARVO meeting

Amakem NV, a kinase platform company focusing on ophthalmology, presented key preclinical data on its potent, locally active Rho Kinase (ROCK) inhibitor AMA0076 at the 2012 Association for Research in Vision and Ophthalmology (ARVO) Annual Meeting being held at Fort Lauderdale, US from 6 - 10 May. The ARVO meeting is the world's largest gathering of international eye and vision researchers.

Researchers discover potential way to develop universal flu vaccines

University of British Columbia researchers have found a potential way to develop universal flu vaccines and eliminate the need for seasonal flu vaccinations.

Metformin blocks uveitis in laboratory rats

University of Texas Medical Branch at Galveston researchers have discovered that a drug already prescribed to millions of people with diabetes could also have another important use: treating one of the world's leading causes of blindness.

Repeating trinucleotide a strong predictor of Fuchs' dystrophy

Mayo Clinic and University of Oregon researchers have confirmed that a genetic factor called a repeating trinucleotide is a strong predictor of an individual's risk of developing the eye condition Fuchs' dystrophy. The findings were being presented today at the annual conference of the Association for Research in Vision and Ophthalmology in Orlando, Fla.

Scientists make important discovery about internal programming of B cells

Scientists at The Scripps Research Institute have made an important discovery about the internal programming of B cells, the immune cells that make antibodies against infections. The finding opens the way for the development of vaccines that can work more efficiently and hints at therapies for conditions in which B cells cause harm—such as the autoimmune disease lupus erythymatosus, severe allergies, and B-cell lymphomas.

Research reveals possible strategy to reverse fibrosis in liver and other organs

An international team of scientists, led by researchers at the University of California, San Diego School of Medicine, report that significant numbers of myofibroblasts - cells that produce the fibrous scarring in chronic liver injury - revert to an inactive phenotype as the liver heals. The discovery in mouse models could ultimately help lead to new human therapies for reversing fibrosis in the liver, and in other organs like the lungs and kidneys.

T2M cells play a crucial role in treatment-resistant asthma

For most people with asthma, a couple of puffs from an inhaler filled with steroids makes breathing easy. But if their lungs become resistant to the calming effect of that medicine, they live in fear of severe asthma attacks that could send them to the hospital - or worse. Now, new research from the University of Michigan Health System may help explain what's going on in the lungs of these steroid-resistant individuals. The findings could aid the development of new treatment options, and of better ways to identify people at risk of becoming steroid-resistant.

Researchers discover CD19 pathway that leads to lymphoma

Researchers studying the molecular signals that drive a specific type of lymphoma have discovered a key biological pathway leading to this type of cancer. Cancerous cells have been described as being "addicted" to certain oncogenes (cancer-causing genes), and the new research may lay the groundwork for breaking that addiction and effectively treating aggressive types of B cell lymphoma.

Zinc oxide could increase risk of skin cancer

As vacationers prepare to spend time outdoors this summer, many of them will pack plenty of sunscreen in hopes it will protect their bodies from overexposure, and possibly from skin cancer. But researchers at Missouri University of Science and Technology are discovering that sunscreen may not be so safe after all.

Specific proteins can help identify patients with IBS

Irritable bowel syndrome (IBS) is hard to diagnose as well as treat, but researchers at the Sahlgrenska Academy, at the University of Gothenburg, Sweden, have discovered a way of confirming the disorder using stool samples.

Various combinations of biomarkers are required to unequivocally diagnose specific disease

With a range of diseases, doctors need unique features which they can use to unequivocally identify a patient's illness for an appropriate diagnosis. Scientists therefore search for the biomarkers for an illness or a combination of biomarkers, known as biosignatures, which are as easy as possible to measure.

Healthy newborns should not be over-protected against natural exposure of gut flora

Infants whose gut is colonised by E. coli bacteria early in life have a higher number of memory B cells in their blood, reveals a study of infants carried out at the Sahlgrenska Academy at the University of Gothenburg, Sweden.
