Plastic device aids robot-assisted heart surgery

Surgical field expansion plate allows surgeons more independence

Robot-assisted heart surgery usually requires an assistant at the operating table to help the surgeon insert the robot arm through a small incision. The assistant has to constantly make sure the surgeon has enough room to operate via the robot arm. For greater independence on the surgeon’s side, an Osaka Metropolitan University-led group has developed a device that can secure the surgical field.

Graduate School of Medicine Professor Toshihiko Shibata and Associate Professor Yosuke Takahashi worked with colleagues and small and medium-sized enterprises to develop the surgical field expansion plate made from a type of plastic used for medical implants and the aerospace industry. They tested the device during actual heart surgery.

When the polyether ether ketone plate is fastened into a circular shape, it expands to a certain size and retains its shape, securing the surgical field. The plate is 0.4 millimeters thick with varying widths and lengths available depending on the requirements of the surgery.

“This flexible yet rigid medical-grade device is simple to use and reusable,” Professor Takahashi stated. “This plate is expected to make it possible to perform robot-assisted heart surgery that is not dependent on the skill of the assistant, with further applications expected in fields such as oral surgery and otolaryngology.”

The findings were published in Innovations.

UVM scientists find space-for-time substitutions exaggerate urban bird–habitat ecological relationships
2024-11-07
As bird populations dwindle across the globe, a new study from University of Vermont researchers suggests some species may be more flexible to habitat changes than previously understood, creating new opportunities for supporting populations through city planting efforts. The team’s findings were published in the Journal of Animal Ecology today. While studies have found bird populations are on the decline—Canada and the United States have lost nearly three billion birds over the last half century—measuring ...

Scientists reveal strigolactone perception mechanism and role in tillering responses to nitrogen

Scientists reveal strigolactone perception mechanism and role in tillering responses to nitrogen
2024-11-07
“How is plant growth controlled?” and “What is the basis of variation in stress tolerance in plants?” were among the 125 most challenging scientific questions, according to the journal Science in 2016. Strigolactone (SL) is an important plant hormone that plays essential roles in regulating branch number, a key growth and development trait for plants. Recently, scientists from the Chinese Academy of Sciences (CAS) have uncovered the mechanism behind SL perception and its key role in the tillering response to nitrogen. The “gas and brake” mechanism of SL perception allows “smart and flexible” regulation of the duration ...

Increasing trend of overweight and obesity among Japanese patients with incident end-stage kidney disease

Increasing trend of overweight and obesity among Japanese patients with incident end-stage kidney disease
2024-11-07
Niigata, Japan - A new nationwide study from Japan spanning a 14 year study period has revealed an increasing trend of overweight and obesity in patients with the incident end-stage kidney disease (ESKD). Although, underweight individuals remain prevalent in this patient population, the study highlights that excessive weight and obesity in patients with the incident ESKD is a shared global challenge. Consequently, the study suggests the need for public health strategies to address the global obesity epidemic as well as underweight individuals in incident ESKD populations. “The global ...

An extra five minutes of exercise per day could help to lower blood pressure

2024-11-07
Adding small amounts of exercise into daily routine, such as climbing stairs or cycling to the shops, could help to reduce blood pressure, with just five additional minutes a day estimated to yield improvements, finds a new study from researchers at UCL and the University of Sydney. The study, supported by the British Heart Foundation (BHF) and published in Circulation, analysed health data from 14,761 volunteers who wore activity trackers to explore the relationship between daily movement and blood pressure. The researchers split daily activity into six behaviours1: Sleep Sedentary behaviour (such as sitting) Slow walking (cadence ...

Five minutes of exercise a day could lower blood pressure

2024-11-07
New research suggests that adding a small amount of physical activity – such as uphill walking or stair-climbing – into your day may help to lower blood pressure.   The study, published in Circulation, was carried out by experts from the ProPASS (Prospective Physical Activity, Sitting and Sleep) Consortium, an international academic collaboration led by the University of Sydney and University College London (UCL).   Just five minutes of activity a day was estimated to potentially reduce blood pressure, while replacing ...

Social media likes and comments linked to young men’s obsession with perfect pecs and a six-pack

2024-11-06
Social media platforms like TikTok and Instagram are fuelling unrealistic, unhealthy obsessions with a lean and muscular physique among many young men, according to a new Australian study. Men who place higher importance on receiving likes and positive comments on their posts are significantly more likely to experience symptoms of what is termed “muscle dysmorphia” (MD) – a belief that their bodies are small and weak, even though many of them have a good physique. In an online survey of almost 100 men, aged between 18-34, all admitted to viewing celebrity, fashion, and fitness content on social media sites, but the link with MD was only significant when it came to ...

$2.1M aids researchers in building chemical sensors to safeguard troops

$2.1M aids researchers in building chemical sensors to safeguard troops
2024-11-06
The U.S. Army has awarded a team of researchers led by Judith Su, University of Arizona associate professor of biomedical engineering and optical sciences, $2.1 million to build a handheld version of her record-breaking FLOWER sensing device for active military personnel. The device picks up target compounds at zeptomolar (10 to the power of negative 21) concentrations, an astonishingly minuscule amount of 600 particles per liter. FLOWER is useful for drug testing and a wide variety of other applications, such as health diagnostics.  The military ...

Climate change parching the American West even without rainfall deficits

2024-11-06
Key takeaways Higher temperatures caused by anthropogenic climate change turned an ordinary drought into an exceptional one that parched the American West from 2020–2022.  A study by UCLA and NOAA scientists has found that evaporation accounted for 61% of the drought’s severity, while reduced precipitation accounted for 39%.  The research found that since 2000, evaporative demand has played a bigger role than reduced precipitation in droughts, which may become more severe ...

Power grids supplied largely by renewable sources experience lower intensity blackouts

Power grids supplied largely by renewable sources experience lower intensity blackouts
2024-11-06
New research into the vulnerability of power grids served by weather-dependent renewable energy sources (WD-RESs) such as solar and wind paints a hopeful picture as various countries around the globe attempt to meet their climate emissions targets – with the research showing grids with high penetration of WD-RESs tend to have reduced blackout intensities in the US. This research – just published in leading international journal Nature Energy – was conducted with US blackout data from 2001 to 2020, but the results are of great interest from the perspective of any country transitioning to power grids primarily ...
