Special coatings to reduce complications after implant surgery

01/07/2020

New coatings on implants could help make them more compatible. Researchers at the Martin Luther University Halle-Wittenberg (MLU) have developed a new method of applying anti-inflammatory substances to implants in order to inhibit undesirable inflammatory reactions in the body. Their study was recently published in the International Journal of Molecular Sciences.

New heart valve could transform open heart surgery

30/06/2020

A new polymeric heart valve with a life span potentially longer than current artificial valves that would also prevent the need for the millions of patients with diseased heart valves to require life-long blood thinning tablets has been developed by scientists at the universities of Bristol and Cambridge. The team’s latest in-vitro results suggest that the PoliValve could last for up to 25 years.

Nanotechnology: first liquid retina prosthesis

30/06/2020

Researchers at IIT-Istituto Italiano di Tecnologia has led to the revolutionary development of an artificial liquid retinal prosthesis to counteract the effects of diseases such as retinitis pigmentosa and age-related macular degeneration that cause the progressive degeneration of photoreceptors of the retina, resulting in blindness. The study has been published in Nature Nanotechnology.

Looking at deep red light improves eyesight

29/06/2020

Staring at a deep red light for three minutes a day can significantly improve declining eyesight, finds a new UCL-led study, the first of its kind in humans. Scientists believe the discovery, published in the Journals of Gerontology, could signal the dawn of new affordable home-based eye therapies, helping the millions of people globally with naturally declining vision.

Portable COVID-19 diagnostic system for rapid on-site testing

29/06/2020

COVID-19 screening can soon be conducted directly at various testing stations, and patients can get their test results in about an hour from the time they get a nasal swab. A team of researchers from the National University of Singapore (NUS) has developed a portable COVID-19 micro-PCR diagnostic system that enables rapid and accurate on-site screening of infectious diseases.

Non-invasive fetal oxygen monitor could make for safer deliveries

26/06/2020

A device to directly measure blood oxygen saturation in a fetus during labor has been developed by researchers at the University of California, Davis. By providing better information about the health of a fetus right before birth, the device could both reduce the rate of Cesarean sections and improve outcomes in difficult deliveries.

Microscopy technique for noninvasive evaluation of wound healing

26/06/2020

Researchers at the GSK Center for Optical Molecular Imaging have developed a new microscope that looks at the different parameters that change during wound healing. They hope to use this technique to understand how skin disorders, such as foot ulcers in diabetic patients and psoriasis, can be treated.

Tiny decoy sponges attract coronavirus away from lung cells

25/06/2020

Imagine if scientists could stop the coronavirus infection in its tracks simply by diverting its attention away from living lung cells? A new therapeutic countermeasure, announced in a Nano Letters study by researchers from Boston University's National Emerging Infectious Diseases Laboratories (NEIDL) and the University of California San Diego, appears to do just that in experiments.

Adhesive film turns smartwatch into biochemical health monitoring system

25/06/2020

UCLA engineers have designed a thin adhesive film that could upgrade a consumer smartwatch into a powerful health-monitoring system. The system looks for chemical indicators found in sweat to give a real-time snapshot of what is happening inside the body. A study detailing the technology was published in the journal of Science Advances.

Intelligent ultrasonic sensors for postoperative bladder monitoring

24/06/2020

After surgeries on the bladder, prostate or kidneys, a permanent irrigation of the bladder is often decisive for a successful healing process. An intelligent system called "VisIMon" was designed to support this. The Fraunhofer Institute for Biomedical Engineering IBMT is developing the miniaturized ultrasound system for automated monitoring of bladder irrigation.
