In four experiments on pig tissues, the robot excelled at suturing two ends of intestine – one of the most intricate and delicate tasks in abdominal surgery

A robot has performed laparoscopic surgery on the soft tissue of a pig without the guiding hand of a human – a significant step toward fully automated surgery on humans.

Designed by a team of Johns Hopkins University researchers, the Smart Tissue Autonomous Robot, or STAR, is described today in Science Robotics.

Senior author Axel Krieger, an assistant professor of mechanical engineering at Johns Hopkins’ Whiting School of Engineering, says: “Our findings show that we can automate one of the most intricate and delicate tasks in surgery: the reconnection of two ends of an intestine.

Meanwhile, fully…

Light therapy helps burn injuries heal faster by triggering growth protein

by

Light therapy may accelerate the healing of burns, according to a University at Buffalo-led study.

The research, published in Scientific Reports, found that photobiomodulation therapy – a form of low-dose light therapy capable of relieving pain and promoting healing and tissue regeneration – sped up recovery from burns and reduced inflammation in mice by activating endogenous TGF‐beta 1, a protein that controls cell growth and division.

The findings may impact therapeutic treatments for burn injuries, which affect more than 6 million people worldwide each year, says lead investigator Praveen Arany, DDS, PhD, assistant professor of oral biology in the UB School of Dental Medicine.

How the surfaces of silicone breast implants affect the immune system

by

Every year, about 400,000 people receive silicone breast implants in the United States. According to data from the U.S. Food and Drug Administration, a majority of those implants needs to be replaced within 10 years due to the buildup of scar tissue and other complications.

A team led by MIT researchers has now systematically analyzed how the varying surface architecture found in these implants influences the development of adverse effects, which in rare cases can include an unusual type of lymphoma.

“The surface topography of an implant can drastically affect how the immune response perceives it, and this has important ramifications for the [implants’] design,” says Omid Veiseh, a former MIT postdoc. “We hope this paper provides a foundation for plastic surgeons to evaluate and better understand how implant choice can affect the patient experience.” [Read more…] about How the surfaces of silicone breast implants affect the immune system

World’s first fiber-optic ultrasonic imaging probe for future nanoscale disease diagnostics

by

Scientists at the University of Nottingham have developed an ultrasonic imaging system, which can be deployed on the tip of a hair-thin optical fibre, and will be insertable into the human body to visualise cell abnormalities in 3D.

The new technology produces microscopic and nanoscopic resolution images that will one day help clinicians to examine cells inhabiting hard-to-reach parts of the body, such as the gastrointestinal tract, and offer more effective diagnoses for diseases ranging from gastric cancer to bacterial meningitis.

The high level of performance the technology delivers is currently only possible in state-of-the-art research labs with large, scientific instruments – whereas this compact system has the potential to bring it into clinical settings to improve patient care.

New technology ‘retrains’ cells to repair damaged brain tissue in mice after stroke

by

Most stroke victims don’t receive treatment fast enough to prevent brain damage. Scientists at the Ohio State University Wexner Medical Center, College of Engineering and College of Medicine have developed technology to “retrain” cells to help repair damaged brain tissue.

It’s an advancement that may someday help patients regain speech, cognition and motor function, even when administered days after an ischemic stroke.

Engineering and medical researchers use a process created by Ohio State called tissue nanotransfection (TNT) to introduce genetic material into cells. This allows them to reprogram skin cells to become something different – in this case vascular cells – to help fix damaged brain tissue.

Study findings published online today in the journal Science Advances. [Read more…] about New technology ‘retrains’ cells to repair damaged brain tissue in mice after stroke

New type of collagen could give cosmetics ‘highest biocompatibility’ with human skin

by

A completely new type of collagen developed by researchers could give cosmetics the “highest biocompatibility” with human skin, possibly leading to less dryness and slower ageing. 

The dream of eternal youth is as old as mankind. There actually is no remedy for the ageing process; that is proved with a simple look in the mirror. Skin ageing is the most visible sign of progressing ageing.

Now scientific findings seem to explain why human skin changes so noticeably. Skin ageing starts as early as in the 20s or 30s, although initially it is hardly visible. Elasticity and resilience decrease and first small wrinkles develop. [Read more…] about New type of collagen could give cosmetics ‘highest biocompatibility’ with human skin

A mathematical study describes how metastasis starts

by

A scientific study carried out by the Universidad Carlos III de Madrid (UC3M) and the Universidad Complutense de Madrid (UCM) has produced a mathematical description of the way in which a tumor invades the epithelial cells and automatically quantifies the progression of the tumor and the remaining cell islands after its progression.

The model developed by these researchers could be used to better understand the biophysical characteristics of the cells involved when developing new treatments for wound healing, organ regeneration, or cancer progression.

This research analyses the collective movement of cells in tissues, a process that, in addition to being essential in pathological developments, such as tumor invasion and metastasis, plays a central role in physiological processes, such as wound healing, embryonic development or tissue reconstruction, for example.
