Innovating in emergencies: A novel technique for removing ceramic liners in hip revision surgery

By Lisa McDonald / May 23, 2023

Innovation in medicine can be slower than in other fields to prevent putting patient safety at risk. Emergencies, however, can necessitate the adoption of new technologies. In an open-access paper, medical professionals in England described the use of a novel technique to extract a ceramic liner during hip revision surgery when established strategies proved ineffective.

Copper-glazed ceramic tiles combat bacteria through hydrophobicity and ion dissolution

By Lisa McDonald / April 28, 2023

Antibacterial ceramic coatings that inactivate or destroy pathogens typically suffer from poor durability. Instead, antibacterial coatings based on hydrophobicity, which inhibits bacterial adhesion, may be more durable. Researchers in South Korea demonstrated the potential of copper-glazed ceramic tiles to maintain long-lasting antibacterial efficiency through a combination of hydrophobicity and bacterial killing via ion dissolution.

Self-sufficient glucose monitoring system successfully manages diabetes in mice

By Lisa McDonald / April 21, 2023

Continuous glucose monitoring systems can help alleviate the mental burden of diabetes management, but there are limitations to powering current systems. Researchers at ETH Zurich developed a self-sufficient glucose monitoring system that not only registers excess glucose but initiates the release of insulin into the blood. They successfully tested the device in mice.

Video: Small case study raises awareness of potential risk of bone stress injuries from carbon-fiber-plated footwear

By Lisa McDonald / March 8, 2023

Carbon-fiber-plated shoes have helped runners to set new world records, but little has been published about the potential injuries that can be sustained from using this technology. Researchers in the United States and Germany published an open-access paper to raise awareness of possible health concerns around the use of carbon-fiber-plated footwear.

Time for removal: A review of erbium laser-assisted ceramic debonding for dental restorations and appliances

By Lisa McDonald / November 18, 2022

Methods that conserve or semi-conserve a dental restoration during removal often risk harming the underlying tooth. Researchers in the U.S. and Poland reviewed the current literature on erbium laser-assisted ceramic debonding to identify the parameters needed for safe application of this method.

Monitoring mental stress: Nanosheet-type tin oxide gas sensors provide quantitative measurement of emotional tension

By Lisa McDonald / October 28, 2022

Determining when to seek help for mental stress can be difficult. However, the recent identification of discernible odor substances that emanate from the skin during emotional tension may offer a way to quantifiably measure mental stress. Two researchers in Japan propose nanosheet-type tin oxides could be used as gas sensors to detect these substances.

Behind the label—study shows diamond rotary instruments marketed for removing zirconia restorations do not perform better than conventional ones

By Lisa McDonald / September 30, 2022

Removal of zirconia dental restorations is challenging and time consuming due to their high strength. Manufacturers offer diamond rotary instruments marketed specifically for removing zirconia restorations, but a new study reaffirmed that these instruments do not perform better or generate less heat than conventional ones.
