Researchers in the UK have achieved the first 3D printing of human corneas that can potentially be used in replacement surgeries. In doing so, they have paved the way for an unlimited and easy-to-fabricate supply of new corneas to patients that need them, they said. Key to the achievement by scientists at Newcastle University is a novel bio-ink—a gel comprised of alginate, a polysaccharide derived from seaweed, and collagen, the main structural protein in cornea. The ink met three key criteria necessary for the fabrication of corneas, Che Connon, professor of tissue engineering at the university, told Design News. In...

NEWCASTLE UPON TYNE, UK (CBS Local) – Researchers at Newcastle University in the United Kingdom have successfully created the first ever 3D-printed cornea, giving millions at risk of going blind new hope. British scientists combined human stem cells with a mixture of alginate and collagen to produce a “bio-ink” that can be used by a 3D printer. The durable yet flexible combination can reportedly be turned into the outer lens of the eye, which light passes through on its way to the retina in less than 10 minutes. “Our unique gel… keeps the stem cells alive whilst producing a materia...

The cornea is a good target for tissue engineering efforts in these early years of the field. It is small, easily accessible, comparatively simple in structure, and the processes for corneal transplantation are already well established. Many older people suffer from corneal damage or degeneration of one form or another, and these patients might benefit from the cost-effective availability of corneas generated from their own cells. Bioprinting is one approach to reducing the cost of building such patient-matched tissue sections, and as noted here, researchers have recently reported success in rapidly printing corneas in thi...

CHICAGO (AP) — They're the tech-age version of donor jars at the diner: crowdfunding websites that aim to link ailing people with strangers willing to help pay for medical treatment. But new research suggests duped patients sometimes crowdfund to pay for bogus stem cell treatments. A study published Tuesday in the Journal of the American Medical Association focused on for-profit clinics that use direct-to-consumer advertising for costly unproven stem-cell treatments for conditions including chronic lung disease, Parkinson's disease, multiple sclerosis and arthritis. Treatments are often marketed as cures or with a pr...

The objective here is a set of tests that (a) match up to the expected outcome based on human trials of mitochondrially targeted antioxidants, and (b) that anyone can run without the need to involve a physician, as that always adds significant time and expense. These tests are focused on the cardiovascular system, particularly measures influenced by vascular stiffness, and some consideration given to parameters relevant to oxidative stress and the development of atherosclerosis. A standard blood test, with inflammatory markers. An oxidized LDL cholesterol assessment. Resting heart rate and blood pressure. Heart r...
