Scientists at The University of Manchester and medical institutes in Italy have identified a gene variant that predisposes people to a special type of heart attack. Their research, published in the International Journal of Cardiology could lead to the development of new drugs to treat the problem. Dr Paolo Tammaro, who led the team, said: "Heart attacks happen when the blood supply to the heart is reduced by the narrowing or blocking of the coronary artery – the vessel that supplies the heart with oxygen and nutrients. Often this is due to fatty deposits which narrow ...

Monday, September 9, 2013, Cleveland: Most patients who report statin intolerance, including muscle aches and other side effects from the cholesterol-lowering drugs, can actually tolerate drugs from this class on subsequent trials, according to research from Cleveland Clinic recently released online and forthcoming in the September issue of the American Heart Journal. The study is the largest ever to examine the effects of re-challenging statin-intolerant patients. Statins are among the most prescribed drugs in the world and are a first-line, highly effective therapy ...

A wide range of biologically inspired materials may now be possible by combining protein studies, materials science and RNA sequencing, according to an international team of researchers. "Biological methods of synthesizing materials are not new," said Melik C. Demirel, professor of engineering science and mechanics, Penn State. "What is new is the application of these principles to produce unique materials." The researchers looked at proteins because they are the building blocks of biological materials and also often control sequencing, growth and self-assembly. RNA ...

Public announcements in noisy places – such as railway stations, airports, or sports venues – could become quieter and clearer in future, thanks to new research. Scientists have developed software that can alter speech before it is broadcast over speakers, making it more audible amid background noise. In a bid to improve current synthetic voice technology, researchers studied how speech was perceived by listeners. They carried out tests to pinpoint the components of speech that are most easily heard by people in a noisy place. Experts at the University of Edinburgh, ...

PITTSBURGH—A wearable, picture-taking health monitor created by University of Pittsburgh researchers has received a recent facelift. Now, in addition to documenting what a person eats, the eButton prototype can accurately match those images against a geometric-shape library, providing a much easier method for counting calories. Published in Measurement Science and Technology, the Pitt study demonstrates a new computational tool that has been added to the eButton—a device that fastens to the shirt like a pin. Using its newly built comprehensive food-shape library, the ...

A nanoparticle shaped like a spiky ball, with magnetic properties, has been uncovered in a new method of synthesising carbon nanotubes by physicists at Queen Mary University of London and the University of Kent. Carbon nanotubes are hollow, cylindrical molecules that can be manipulated to give them useful properties. The nanoparticles were discovered accidentally on the rough surfaces of a reactor designed to grow carbon nanotubes. Described as sea urchins because of their characteristic spiny appearance, the particles consist of nanotubes filled with iron, with ...

WHAT: National Institutes of Health (NIH) scientists report that a combination of two licensed antiviral drugs reduces virus replication and improves clinical outcome in a recently developed monkey model of Middle East respiratory syndrome coronavirus (MERS-CoV) infection. Their study, which appears as a letter in the Sept. 8 edition of Nature Medicine, expands on work published in April showing that a combination of ribavirin and interferon-alpha 2b stops MERS-CoV from replicating in cell culture. Both antivirals are routinely used together to treat viral diseases such ...

New research from the University of East Anglia shows that rising ocean temperatures will upset natural cycles of carbon dioxide, nitrogen and phosphorous. Plankton plays an important role in the ocean's carbon cycle by removing half of all CO2 from the atmosphere during photosynthesis and storing it deep under the sea – isolated from the atmosphere for centuries. Findings published today in the journal Nature Climate Change reveal that water temperature has a direct impact on maintaining the delicate plankton ecosystem of our oceans. The new research means that ocean ...

SAN ANTONIO (Sept. 8, 2013) — Biologists reported today in Nature that they have identified two pathways through which chromosomes are rearranged in mammalian cells. These types of changes are associated with some cancers and inherited disorders in people. "Our finding provides a target to prevent these rearrangements, so we could conceivably prevent cancer in some high-risk people," said senior author Edward P. (Paul) Hasty, D.V.M., of the School of Medicine at The University of Texas Health Science Center at San Antonio. Partial funding came from the Cancer Therapy ...
