Biofilm discovery suggests way to prevent infections

02/06/2017

Microbial biofilms - dense, sticky mats of bacteria that are hard to treat and can lead to dangerous infections - often form in medical equipment, such as flexible plastic tubing used in catheters or in tubes used to help patients breathe. By some estimates, more than 1 million people contract infections from medical devices in U.S. hospitals each year, many of which are due to biofilms.

Metamaterial-enhanced MRI technique tested on humans

01/06/2017

Scientists from the Netherlands and Russia designed and tested a new metasurface-based technology for enhancing the local sensitivity of MRI scanners on humans for the first time. The metasurface consists of thin resonant strips arranged periodically. Placed under a patient's head, it provided much higher signals from the local brain region.

Zapping bacteria with sanitizers made of paper

03/05/2017

Imagine wearing clothes with layers of paper that protect you from dangerous bacteria. A Rutgers-led team has invented an inexpensive, effective way to kill bacteria and sanitize surfaces with devices made of paper.

Control of molecular motion by metal-plated 3-D printed plastic pieces

01/05/2017

Many measurement techniques, such as spectroscopy, benefit from the ability to split a single beam of light into two in order to measure changes in one of them. The crucial device that separates the beam is the beam-splitter. These have been mostly limited to light beams, where one uses simply a partially reflective glass.

Rapid screening machine can read and separate protein sequences

27/04/2017

The structural properties of proteins that could eventually become important materials for manufacturing and medicine are revealed by a novel optical technique that works rapidly to sort through amino acid sequences even inside living bacteria, according to a team of engineers.

Hip joint: sleeve versus endoprosthesis

10/04/2017

People with hip osteoarthritis often suffer from severe pain and only an endoprosthesis implantation can provide relief. This involves a major intervention and long-term rehabilitation because the implant requires the removal of a section of the thigh bone. The "MioHIP" research project looks for an elastic alternative.

RealSpine: realistic surgical simulation

22/02/2017

Surgeons need a great sense of touch. They first have to acquire this skill in simulation training before they can perform surgery on actual patients. Having said that, simulators are not just meant to teach the right movements; ideally, they should also provide a true-to-life experience of the surgical field – as is the case in RealSpine surgical training.

A new broom sweeps clean? The new EU Medical Device Regulation

10/10/2016

The year 2016 brings about the new, eagerly anticipated Medical Device Regulation (MDR). The revision needs to now be implemented by all EU member states in the coming years after there have been ongoing deliberations and negotiations since October 2012.

Textiles used in hospitals and medical offices – germs don’t stand a chance

01/06/2016

Some hospitals have long banned the status symbol of physicians – the white coat. Research has shown that especially the sleeves were contaminated with various types of bacteria. But it’s not just lab coats that can spread germs in healthcare settings. This field uses a variety of different textiles. Wouldn’t it, therefore, make sense to apply antimicrobial finishes?

Safe or Not Safe? "The AB-DES has not gained market access in countries like Japan or the U.S."

01/05/2016

Antibody-coated, drug-eluting stents (AB-DES) feature an exterior coated with immunosuppressant drugs and an interior that is coated with antibodies to accelerate the adhesion of endothelial cells. In theory, this makes it possible to shorten the duration of therapy with blood thinners, which can mean relief for patients from an already difficult situation.

Melt electrospinning writing: polymer fibers for tissue engineering

01/02/2016

Sometimes, soft tissue in our body needs to be replaced after surgery or an injury. But surgeons are not always able to take tissue from other body parts as a replacement. Then, they need to use implants. The production of soft implants that can constantly endure load and stress like our own tissue is a big challenge for research. Melt electrospinning writing can be a solution.

Theranostics: Complex particles for tomorrow's medicine

01/10/2015

It is a portmanteau, a mixture of two words. This way it saves us time and trouble while speaking because the human speech apparatus is lazy. And it describes a mixture of procedures: the combination of two procedures that would normally be separate in medicine. We are talking about theranostics.

Gently administering drugs with a membrane containing active ingredients

09/02/2015

Injections are not popular with either children or adults. For years, researchers have therefore been looking for a way to administer drugs in a gentler manner. Swiss scientists now developed a membrane that releases active ingredients under ultraviolet light. It could revolutionize how drugs and vaccines are being administered.
