At the OSA Biophotonics Congress: Biomedical Optics meeting, held 3-6 April in Hollywood, Florida, USA, researchers from Milan, Italy, will report an advance in instrument development that increases the sensitivity of OM by as much as 1000-fold.
A multi-institutional study supports the value of a biomarker to accurately diagnose or rule out acute heart failure in patients seen for shortness of breath at hospital emergency departments.
Neurology researchers investigating a rare but devastating neurological regression in infants have discovered the cause: gene mutations that severely disrupt crucial functions in mitochondria, the energy-producing structures within cells. The specific disease mechanism, in which mutations disrupt a critical mitochondrial enzyme, has not previously been implicated in a human disease.
In an outbreak of Legionnaires' disease, finding the exact source as quickly as possible is essential to preventing further infections. To date, a standard analysis takes days. Researchers at the Technical University of Munich have now developed a rapid test that achieves the same result in about 35 minutes.
Patients who survive a brief cardiac arrest and who appear neurologically intact should nonetheless receive a detailed neuropsychological assessment before being discharged, suggests a joint study by researchers at Baycrest's Rotman Research Institute (RRI) and Israel's Rambam Medical Center.
The average size of breast cancers at diagnosis decreased dramatically in the 1980s and 1990s following the introduction of screening, according to research presented at the 11th European Breast Cancer Conference.
An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Professor Michael N. Hall from the Biozentrum, University of Basel, report in Nature that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
A new study has identified two genes associated with hyperemesis gravidarum, whose cause has not been determined in previous studies. The genes, known as GDF15 and IGFBP7, are both involved in the development of the placenta and play important roles in early pregnancy and appetite regulation.
By converting brain waves into sound, even non-specialists can detect 'silent seizures' -- epileptic seizures without the convulsions most of us expect.
Tiny floating robots could be useful in all kinds of ways, for example, to probe the human gut for disease or to search the environment for pollutants. In a step toward such devices, researchers describe a new marriage of materials, combining ultrathin 2-D electronics with miniature particles to create microscopic machines. The researchers will present their results today at the 255th National Meeting & Exposition of the American Chemical Society.
