Bioactive near-infrared II clusters for 3D imaging and acute inflammation inhibition

Posted by in categories: biotech/medical, engineering, neuroscience

The bioactivity of most near-infrared II (NIRII) fluorophores are limited, thereby conflicting the achievement of strong fluorescence and high catalytic activities, due to a lack of free electrons in the method.

To overcome this challenge, Huizhen Ma and a research team in translational medicine, , physics, and materials at the Tianjin University China developed atomically precise gold clusters with strong near-infrared II fluorescence to show potent enzyme-mimetic activities by using atomic engineering, to form active copper single-atom sites.

These gold-copper clusters (Au21 Cu1) showed higher antioxidant nature with a 90-fold catalase-like and 3-fold higher superoxide dismutase-like activity compared to gold clusters alone. These clusters can be cleared through the to monitor cisplatin-induced within a 20–120-minute window to visualize the process in 3D via near-infrared light-sheet microscopy.

New Breakthrough Paves the Way for Extending Human Lifespan — Scientists Successfully Transfer Longevity Gene

Posted by in categories: biotech/medical, life extension

The successful transfer of a gene that produces HMW-HA paves the way for improving the health and lifespan of humans, too. In a groundbreaking endeavor, scientists at the University of Rochester have successfully transferred a longevity gene from naked mole rats to mice, leading to enhanced health and increased lifespan. Naked mole rats, noted for their resistance to age-related diseases, have a gene that produces high molecular weight hyaluronic acid (HMW-HA), which when introduced to mice, demonstrated potential anti-aging benefits.

Smart contact lens battery charged by human tears

Posted by in categories: biotech/medical, mobile phones

The battery can be charged for up to 200 cycles and does not contain wires or toxic heavy metals.

Researchers at the Nanyang Technological University (NTU) in Singapore have devised a micrometer-thin battery that can power smart contact lenses and be charged with tears, a university press release said.

Mitochondria pore emerges as potential key to managing muscular dystrophies

Posted by in category: biotech/medical

Ever since the Jerry Lewis telethons began in the 1960s, millions of people have become familiar with an otherwise rare disease called muscular dystrophy (MD).

The medical world has learned much over the ensuing years, including that more than 30 closely related disorders exist that can produce the gradual muscle degeneration that steals a child’s ability to walk and eventually disrupts other organ functions. An estimated 250,000 people in the U.S. are living with a muscular dystrophy. While many are living longer lives thanks to improved treatments, no cure has been found.

Now an eye-opening study led by scientists at Cincinnati Children’s—published Aug. 25, 2023, in Science Advances —reports an entirely new approach to preventing the muscle-wasting symptoms of MD. The research focuses on the role played by mitochondria, the tiny organelle within our cells that processes nutrients into the energy cells need to survive.

Gilded mysteries unveiled: Ancient art meets nanotechnology in nanoscale goldbeating

Posted by in categories: biotech/medical, nanotechnology

Goldbeating, an age-old craft pioneered by ancient Egyptian artisans more than five millennia ago, involves the meticulous thinning of bulk gold into gossamer-like leaves. Throughout history, this intricate process has adorned various masterpieces, such as the tombs of Thebes and Saqqara, and has cemented its place in art and adornments across cultures. Today, nanoscale gold is used not only for decorating fancy desserts, but is indispensable for modern applications ranging from microelectronics to nanomedicine.

Hospital Computers Offline for Weeks Due to Cyberattack

Posted by in categories: biotech/medical, cybercrime/malcode

This post is also available in: he עברית (Hebrew)

Important computer systems at hospitals and clinics have been offline for over two weeks after a cyberattack forced emergency room shutdowns and ambulance diversions. According to Prospect Medical Holdings, progress is being made “to recover critical systems and restore their integrity,” but the company, which runs 16 hospitals and dozens of other medical facilities in various states could not say when operations will return to normal.

The recovery process for this situation can often take weeks, and in the meantime, hospitals are reverting to paper systems and people to monitor equipment, run records between departments, and do other tasks that are usually electronic.
