This is the question that experts in medicine and medical informatics at Friedrich-Alexander Universität Erlangen-Nürnberg (FAU) aim to find answers to in a new research project called ‘MelEVIR – Melanoma, Extracellular Vesicles and Immune Response’.
24/06/2016Researchers have discovered a simple, accurate new way to predict which women with gestational diabetes will develop type 2 diabetes after delivery. The discovery would allow health care providers to identify women at greatest risk and help motivate women to make early lifestyle changes and follow other strategies that could prevent them from developing the disease later in life.
24/06/2016The new stem cell-containing bio ink allows 3D printing of living tissue, known as bio-printing. The new bio-ink contains two different polymer components: a natural polymer extracted from seaweed, and a sacrificial synthetic polymer used in the medical industry, and both had a role to play.
22/06/2016Chronic myeloid leukemia (CML) develops through chromosomal alterations in blood-forming cells of the bone marrow and usually occurs in older persons. Around 20 percent of adults diagnosed with leukemia suffer from this type of blood cancer.
21/06/2016When we smoke cigarettes, dozens of genes important for immune defense are altered in the epithelial cells that line the respiratory tract. Several of these changes likely increase the risk of bacterial infections, viruses, and inflammation. Now, electronic cigarettes alters those same genes and hundreds more that are important for immune defense in the upper airway.
17/06/2016A tiny mirror could make a huge difference for scientists trying to understand what's happening in the micron-scale structures of living cells.
16/06/2016hen the body is fighting an invading pathogen, white blood cells including T-cells must respond. Now, Salk Institute researchers have imaged how vital receptors on the surface of T cells bundle together when activated.
14/06/2016In a randomized Phase III study of the drug inotuzumab ozogamicin, a statistically significant percentage of patients with acute lymphoblastic leukemia (ALL) whose disease had relapsed following standard therapies, qualified for stem cell transplants.
13/06/2016Scientists at the German Center for Neurodegenerative Diseases (DZNE), the Hertie Institute for Clinical Brain Research and the University of Tübingen have identified proteins in the blood and cerebrospinal fluid that reflect nerve cell damage.
02/06/2016Growing tissues and organs in the lab for transplantation into patients could become easier after scientists discovered an effective way to produce three-dimensional networks of blood vessels, vital for tissue survival yet a current stumbling block in regenerative medicine.
01/06/2016Two new optical devices could reduce the need to take tissue samples during medical examinations and operations and to then send them for testing – potentially speeding up diagnosis and treatment and cutting healthcare costs.
31/05/2016When it comes to measuring brain activity, scientists have tools that can take a precise look at a small slice of the brain (less than one cubic millimeter), or a blurred look at a larger area. Now, researchers at Rockefeller University have described a new technique that combines the best of both worlds - it captures a detailed snapshot of global activity in the mouse brain.
24/05/2016For cancer to spread, the cells that take off into the bloodstream must find a tissue that will permit them to thrive. They don't just go looking, though. Instead, they actively prepare the tissue, in one case by co-opting a protein that suppresses defenses the body would otherwise mount.
