Low-cost jaundice detector passes first test in Africa
The first clinical study of a low-cost, hand-held jaundice detector invented by Rice University students couldn’t have come at a better time for NEST360°, an international team of scientists, doctors and global health experts preparing for a competition for $100 million from the MacArthur Foundation. The money would allow the team to carry out its visionary plan to halve the number of newborn deaths in African hospitals within 10 years.
Building virus-sized structures through mass production
It is the double strands of our genes that make them so strong. Using a technique known as DNA origami, biophysicist Hendrik Dietz has been building nanometer-scale objects for several years at the Technical University of Munich (TUM). Now Dietz and his team have not only broken out of the nanometer realm to build larger objects, but have also cut the production costs a thousand-fold. These innovations open a whole new frontier for the ...
Orthopaedic product has the potential to improve bone apposition
Omnia Medical VBR has been granted the first US FDA 510(k) clearance for a vertebral body replacement (VBR) system manufactured from PEEK-OPTIMA HA Enhanced polymer, from Invibio Biomaterial Solutions, for use in the thoracolumbar spine to replace a collapsed, damaged, or unstable vertebral body.
Breast imaging could reduce false positive examinations
Seno Medical Instruments, Inc. has announced positive data from PIONEER, a Phase III pivotal trial of its Imagio breast imaging system. The study found that OA/US was more specific than device gray-scale ultrasound alone (US) in differentiating malignant from benign breast lesions and was non-inferior to US with respect to sensitivity. This means that OA/US detected a similar number of malignant lesions as US but had a lower rate of false po...
Forming a bioactive spider silk for medical use
With recent advances, technology can be used to synthesise silk with similar mechanical properties as an actual spider’s. But applying this material to promising medical therapies for illnesses such as cancer requires that humans develop a capability that only arachnids or silkworms possess – the ability to control the formation of silk.
Biocompatible ink for 3D printing makes use of living bacteria
A group of ETH researchers led by Professor André Studart, Head of the Laboratory for Complex Materials, has now introduced a 3D printing platform that works using living matter. The researchers developed a bacteria-containing ink that makes it possible to print mini biochemical factories with certain properties, depending on which species of bacteria the scientists put in the ink.
Study examines the interaction of human cancer inhibitors
Medications which block enzymes belonging to the kinase family, are among the most effective pharmaceuticals for targeted cancer therapies. Scientists at the German Cancer Consortium (DKTK) at the Technical University of Munich (TUM) have examined 243 kinase inhibitors which are either approved drugs or have been tested in clinical trials. According to results published in Science, some of these may have more applications than previously thought.
'Getting in sync' with your baby
Making eye contact with an infant makes adults’ and babies’ brainwaves ‘get in sync’ with each other – which is likely to support communication and learning – according to researchers at the University of Cambridge. When a parent and infant interact, various aspects of their behaviour can synchronise, including their gaze, emotions and heartrate, but little is known about whether their brain activity also ...
Method could be used in targeted cancer therapeutics
Inspired by white blood cells rolling on endovascular walls before transmigrating to the disease site, scientists at ETH Zurich have succeeded in getting particles to move along the walls of microscopic, three-dimensional vessels. This method could be used in targeted cancer therapeutics. When white blood cells are summoned to combat invasive bacteria, they move along blood vessels in a specific fashion, i.e., like a ball propelled by t...
Brain stimulation improves cognition in Parkinson's disease
A multidisciplinary neuroscience study using rare, intraoperative brain recordings suggests that low frequency stimulation of a deep brain region may be able to improve cognitive function in patients with Parkinson's disease (PD). The study findings, published in the journal Brain, also hint at the broader potential of brain stimulation for treating other cognitive diseases.
