What is the largest ligament in the human body? It might surprise some people that it is the Achilles tendon. Even though it is also considered the toughest ligament, the Achilles tendon can rupture, with many such injuries involving sports enthusiasts in their 30s or 40s. Surgery might be required, and a prolonged period of rest, immobilization, and treatment can be difficult to endure.

Seeking to shorten the recovery time, a research team led by Osaka Metropolitan University Graduate School of Medicine’s Katsumasa Nakazawa, a graduate student in the Department of Orthopedic Surgery, Associate Professor Hiromitsu Toyoda, and Professor Hiroaki Nakamura, and Graduate School of Engineering Professor Jun-Seok Oh has focused on non-thermal atmospheric-pressure plasma as a treatment method.

This study is the first to show that such plasma irradiation can accelerate tendon repair. The team ruptured then sutured the Achilles tendon of lab rats. For one group of rats, the sutured area was irradiated with a helium plasma jet. The plasma-irradiated group exhibited faster tendon regeneration and increased strength at two, four, and six weeks after surgery compared to the untreated group.

“We have previously discovered that irradiation of non-thermal atmospheric-pressure plasma has the effect of promoting bone regeneration. In this study, we discovered that the technology also promotes tendon regeneration and healing, showing that it has applications for a wide range of fields,” Professor Toyoda declared. “Combined with current tendon treatments, it is expected to contribute to more reliable tendon regeneration and shorter treatment time.”

The results were published in PLOS ONE.

Screen time not the main factor making parent-child interactions worse, study finds

2024-05-21
Technology use is at an all-time high and understanding how this impacts daily life is crucial. When it comes to parent-child interactions, scientists have coined the term ‘technoference,’ meaning technology interference. It occurs when parent-child interaction and communication are disrupted by the use of digital devices. But is distraction caused by digital devices more detrimental to parent-child interaction than when parental distraction comes from different sources? Researchers in Switzerland have investigated. “In this study, we show that ...

Improving the effectiveness of earthquake early warning systems

Improving the effectiveness of earthquake early warning systems
2024-05-21
Mobile phones have become invaluable for receiving emergency alerts such as weather warnings, evacuation notices and notifications about missing persons. In Japan, where earthquakes are frequent, they are vital for delivering earthquake warnings and advising people to take protective actions beforehand. To deal with such situations promptly, the Earthquake Early Warning (EEW) system sends out notifications to areas expected to experience strong tremors by detecting primary seismic waves (P-waves) that arrive before the secondary waves (S-waves). However, the short time between receiving the notification and the arrival of S-waves ...

Addressing homelessness in older people

2024-05-21
Homelessness doesn’t only happen to young people but also affects older adults in growing numbers, write authors in an analysis in CMAJ (Canadian Medical Association Journal) that describes this emerging crisishttps://www.cmaj.ca/lookup/doi/10.1503/cmaj.231493. People experiencing homelessness are considered older adults at age 50, as visible aging is often evident at younger ages in individuals experiencing homelessness compared with individuals who have secure housing. Individuals experiencing homelessness often develop chronic ...

One in 5 adults in Canada without access to primary care

Researchers develop perovskite X-ray detector for medical imaging

Researchers develop perovskite X-ray detector for medical imaging
2024-05-21
Technology (SIAT) of the Chinese Academy of Sciences, in collaboration with researchers at Central China Normal University, have developed a high-performance perovskite X-ray complementary metal-oxide-semiconductor (CMOS) detector for medical imaging. The study was published in Nature Communications on Feb. 21. X-ray imaging is vital for the diagnosis and treatment of cardiovascular and cancer diseases. Direct-conversion X-ray detectors made of semiconductor materials exhibit superior spatial and temporal resolution at lower radiation doses compared to indirect-conversion detectors made of scintillator materials. However, the currently available semiconductor ...
