03/04/2019From birth through to death, cells lead an eventful existence. Thanks to single-cell genomics, their destiny can be analyzed. But this method destroys the cell. In order to address this problem, researchers at the Helmholtz Zentrum München and the University of Massachusetts use pseudodynamics, a mathematical model that estimates developmental processes from single-cell time series observations.
02/04/2019An essential part of breast intervention is the process of assessing concordance between imaging findings and core biopsy results. When pathology results are considered benign discordant, current standard of care is surgical excision, even though many of these lesions will ultimately be found benign.

22/03/2019The heart exerts muscular force by contracting numerous contractile units of the heart muscle. Biologists at Münster University have found out that a specific motor protein is responsible for the assembly and mechanical stability of these contractile units in the heart. The study has been published in “The Journal of Biological Chemistry”.
22/03/2019Over six million people in Germany have diabetes. It is estimated that almost 400 million people are affected by this disease worldwide. Diabetes sufferers must prick their fingers several times a day to monitor their blood sugar.
22/03/2019A one-off operation that targets the nerves connected to the kidney has been found to maintain reduced blood pressure in hypertension patients for at least six months, according to the results of a clinical trial led in the UK by Queen Mary University of London and Barts Health NHS Trust, and supported by the National Institute for Health Research (NIHR).
21/03/2019A computed tomography (CT) scan of the head is routinely performed as a check after operating a subdural haematoma. However, this may prompt additional, unnecessary surgeries and result in higher costs as well as an increased rate of complications, without recognizable benefits for the patients.
08/03/2019Brown University researchers have developed a new antibacterial coating for intravascular catheters that could one day help to prevent catheter-related bloodstream infections, the most common type of hospital-acquired infection.
05/03/2019A new ultrasensitive diagnostic device invented by researchers at the University of Kansas, The University of Kansas Cancer Center and KU Medical Center could allow doctors to detect cancer quickly from a droplet of blood or plasma, leading to timelier interventions and better outcomes for patients.
26/02/2019The technology, developed by researchers at Imperial College London and The University of Hong Kong, can be used to measure hormones that affect fertility, sexual development and menstruation more quickly and cheaply than current methods.
08/02/2019Researchers at Rensselaer Polytechnic Institute who developed a blood test to help diagnose autism spectrum disorder have now successfully applied their distinctive big data-based approach to evaluating possible treatments.
04/02/2019To provide sufficient oxygen to tissues and organs within the body, blood vessels need to sprout new offshoots to form a widespread blood supply network, much like the trunk, branches, and twigs of a tree. However, the mechanisms by which this sprouting occurs, in both normal healthy conditions and in conditions like cancer, have remained unclear.
29/01/2019Researchers have developed a simple blood test that can detect when a newly transplanted lung is being rejected by a patient, even when no outward signs of the rejection are evident.
28/01/2019Some people use fidget spinners - flat, multi-lobed toys with a ball bearing at the center - to diffuse nervous energy or whirl away stress. Now, researchers have found a surprising use for the toys: separating blood plasma for diagnostic tests.
24/01/2019Small infections can be fatal: Millions of people die each year from sepsis, an overreaction of the immune system. A new immune signaling molecule, designed by a research team from the Technical University of Munich (TUM), now provides the basis for potential new approaches in sepsis therapy.
23/01/2019Years before symptoms of Alzheimer’s disease manifest, the brain starts changing and neurons are slowly degraded.
23/01/2019A previously unknown network of fine capillaries directly connecting the bone marrow with the circulation of the periosteum has been discovered.
22/01/2019Researchers from the Department of Biomedical Research of the University of Bern and the University Clinic of Visceral Surgery and Medicine of the Inselspital Bern, Switzerland, have discovered that changes in the composition of the intestinal bacteria in patients with chronic inflammatory bowel disease affect the severity of the disease and the success of therapy.
21/01/2019In the largest study to date of rapid TB tests used by the NHS, a team led by researchers at Imperial College London found that available tests are not sensitive enough to rule out a diagnosis of TB in suspected cases, and so have limited clinical use.
21/01/2019Pilot study by Brigham investigators finds that an innovative care-delivery program helped 81 percent of participants achieve blood pressure control in seven weeks.
21/11/2018Our blood reveals a lot about our physical health. The shape of our blood cells sheds light on several hereditary diseases for example. For a diagnosis, the cells must first be examined under the microscope and categorized into a specific cell class. We met with Dr. Stephan Quint and Alexander Kihm of the Institute of Physics at the Saarland University, who explained how this classification works.
02/11/2018This is what diagnostic investigation normally looks like: a patient sample is collected, sent to the laboratory and analyzed. Once that's completed, the patient is told of the lab test result. But if the patient is a high-performance athlete and has to follow and stick to a rigid training schedule, he or she needs these results immediately. What makes this possible? Point-of-care testing!
22/06/2018A drop of blood provides a lot of valuable information. However, it takes several hours to analyze the blood of a patient and make a diagnosis. This takes away a lot of time that's crucial for treatment. A new method intends to considerably speed up this process by testing the cells in the blood in terms of their deformability and immune response.
20/12/2017Sixty percent of newborns are affected by jaundice during their first days of life. In most cases, the condition is harmless. The ailment is more pronounced in premature babies, whose treatment involves irradiation with blue light in a special incubator – naked and alone.
01/08/2017Advances in technology and analysis techniques, as well as the increasing miniaturization of laboratory equipment and processes, make it possible: patient-side laboratory testing, better known as point-of-care testing or POCT. There are many POCT projects and all of them promise a rapid diagnosis as well as economic advantages. But are these tests also suited for everyday medical testing?
01/08/2017Many therapeutic drugs are very powerful, but they are also very toxic at the same time. Thus, they have to be measured regularly, again and again, so that an adjustment of the individual drug dosage can be made. Until now, the "normal" way was to take the blood sample, send it to a central laboratory and get the results after some days. A new point-of-care test can measure it in 15 minutes.
24/07/2017A new analysis method that uses fetal DNA extracted from the mother’s blood is designed to non-invasively reach a prenatal diagnosis of genetic disorders in a child. A task force of the Hahn Schickard Society for Applied Research is an active part of the "ANGELab" project and co-developed this diagnostic procedure.
