Together with the company Tissuegnostics, the pathologist Lukas Kenner and his colleagues have developed a software that is able to identify cancer cells in tissue sections and demonstrate the presence of specific biomarkers on cells. The overall information provides a precise picture of the disease and leads to the most suitable treatment.
According to the results of the study, "Two independent pathologists concur with each other only in regard of every third diagnosis."
The public perception that No Child Left Behind has increased burnout and lowered job satisfaction among teachers is unfounded, according to a recent study co-authored by UT Dallas researcher Dr. James R. Harrington.
The study, which was published online in Educational Evaluation and Policy Analysis, a peer-reviewed journal of the American Educational Research Association, found that, overall, the accountability pressures of No Child Left Behind (NCLB) did not have much of an impact on teachers' job satisfaction or commitment to the profession.
CLEVELAND, Ohio (July 14, 2014)—In the 2,500+ years that have passed since acupuncture was first used by the ancient Chinese, it has been used to treat a number of physical, mental and emotional conditions including nausea and vomiting, stroke rehabilitation, headaches, menstrual cramps, asthma, carpal tunnel, fibromyalgia and osteoarthritis, to name just a few.
Antibiotic resistance is depleting our arsenal against deadly diseases and infections, such as tuberculosis and Staph infections, but recent research shows promise to speed up the drug discovery process.
In a study reported in ACS Chemical Biology, University of Illinois researchers developed a new technique to quickly uncover novel, medically relevant products produced by bacteria.
For the Spanish Royal Academy, senescent is he who "begins to age". But laboratory biology results are contradicting the dictionary: not only is senescence not a synonym of ageing, it is also not intrinsically negative for the organism. Cellular senescence is such a badly named physiological process that those who do research in this area think it needs another name. That is the case of Manuel Serrano, from the Spanish National Cancer Research Centre (CNIO), one of the world's leading experts on senescence, who has just published a review on this topic.
Superconductors are futuristic materials that will hopefully have a broad range of technological applications at some time in the future (medical imaging, transport…). Today's use is limited by the extremely low temperatures (close to absolute zero) required for superconductivity to manifest. However, some families of these materials work at "relatively" high temperatures (about - 200° C), and it's on these that scientists are focusing their attention. Among them are copper-based superconductors, which have very unique characteristics.
Is cancer an inevitable consequence of aging?
Although it is widely thought that cancer is an inevitable consequence of aging, the risk of developing several common cancers decreases with age.
Researchers have long been puzzled by the apparent decrease with age in the risk of developing certain adult cancers.
A possible solution to this puzzle was presented in a recent paper published in Biophysical Reviews and Letters by Professor James P. Brody of the Department of Biomedical Engineering at the University of California, Irvine.
Serendipity leads University of Kansas scientists to the discovery and description of Rhipidocyrtus muiri - a 107 year old, lost in collections specimen, which turned out to represent a new genus and species. The long and tortuous history of the enigmatic ripidiine wedge beetle from Borneo is discussed in a recent paper published in the open access journal ZooKeys.
Honey bees with roots in the local environment manage much better in the struggle for survival than imported honey bees from foreign environments.
A world without bees would be a whole lot poorer – literally. In Denmark alone an additional 600 million to 1 billion Danish kroner are earned annually due to the work done by bees making honey and pollinating a wide range of crops from apples to cherries and clover.
The Roquin protein, discovered in 2005, controls T-cell activation and differentiation by regulating the expression of certain mRNAs. In doing so, it helps to guarantee immunological tolerance and prevents immune responses against the body's own structures that can lead to autoimmune disease. Roquin is thus an immune regulator. Autoimmune diseases affect between five and ten per cent of the population. They usually occur as a result of complex environmental influences when a genetic predisposition exists.
In close collaboration with Jürg Schönenberger and Yannick Städler from the Department of Botany and Biodiversity Research of the Faculty of Life Sciences, University of Vienna, 14 developmental stages of the flower of Arabidopsis thaliana from very early meristematic floral initiation to fully developed seeds were monitored with micro-computed tomography in 3D. From the same set of developmental stages a full metabolic profile using mass spectrometry was measured covering hundreds of biochemical pathways.
Early maize farmers selected for genes that improved the harvesting of sunlight, a new detailed study of how plants use 'doubles' of their genomes reveals. The findings could help current efforts to improve existing crop varieties.
A new theory of how cancer works could lead to the next generation of treatments of the disease.
The theory suggests that cancer forms when recently evolved genes are damaged, and cells have to revert to using older, inappropriate genetic pathways.
Astrobiologists Dr Charley Lineweaver from The Australian National University and Professor Paul Davies from Arizona State University teamed up with oncologist Dr Mark Vincent from the University of Western Ontario to develop the new model.
ATLANTA – July 14, 2014 –Physical fitness may buffer some of the adverse health effects of too much sitting, according to a new study by researchers from the American Cancer Society, The Cooper Institute, and the University of Texas. The study appears in the journal Mayo Clinic Proceedings, and finds the association between prolonged sedentary time and obesity and blood markers associated with cardiovascular disease is markedly less pronounced when taking fitness into account.
