A new study has revealed a technology how to cover biodegradable implants with a human skeleton similar mineral. Bone tissue regeneration, one of the issues of tissue engineering, is a research area for Dmitry Gorin and his international colleagues, a leading research fellow at the RASA Center in Tomsk Polytechnic University. The scientists have developed a new vaterite-based coating for nanofiber scaffold to grow bone tissue cells in a shorter time.

The process of porous calcium carbonate (CaCO3) covering on electrospun poly(ε-caprolactone) (PCL) fibers was ...

New Graphene-based system could help us see Electrical Signaling in Heart and Nerve cells

Image - This diagram shows the setup for an imaging method that mapped electrical signals using a sheet of graphene and an infrared laser. The laser was fired through a prism (lower left) onto a sheet of graphene. An electrode was used to send tiny electrical signals into a liquid solution (in cylinder atop the graphene), and a camera (lower right) was used to capture images mapping out these electrical signals.

A cutting edge, non-invasive brain stimulation technique could improve cognitive control for people with conditions such as schizophrenia and autism, ADHD. Researchers at The University of Queensland’s Centre for Clinical Research have found the technique – which applies high-definition transcranial direct current stimulation to a particular area of the brain – improves cognitive and conflict control.

PhD candidate Oyetunde Gbadeyan said the study provides th...

Turning therapeutic Antibodies inside-out to fight Cancer

Turning therapeutic antibodies inside-out to fight cancer

A schematic showing how a human monoclonal antibody containing a loop structure (CDR-H3) inspired by antibodies found naturally in camels can bind to matrix metalloproteinase 14, which has been shown to play a significant role in several types of cancer.

Researchers at the University of California, Riverside have camels and llamas to thank for their development of a new cancer treatment that is highly selective in blocking the action of faulty matrix metalloproteinases (MMPs). MMPs are a group of 26 closely related proteinases (enzymes that break down other proteins) that are essential in tissue regeneration and other normal cellular processes. However, when a tumor grows, certain MMPs are over-produced, allowing cancer cells to spread to other parts of the body.

Assistant professor Xin Ge...
