Handheld 3D Skin Printer Demonstrates Accelerated Healing of Large, Severe Burns

Researchers develop a skin printer that works like a paint roller, depositing bio ink that speeds up wound healing. A new handheld 3D printer can deposit sheets of skin to cover large burn wounds – and its “bio ink” can accelerate the healing process.

The device, developed by a team of researchers from the University of Toronto Engineering and Sunnybrook Hospital, covers wounds with a uniform sheet of biomaterial, stripe by stripe.

The bio ink dispensed by the roller is composed of mesenchymal stroma cells (MSCs) — stem cell...

Unique new Antiviral Treatment made using Sugar

Virucide treatment before after

New antiviral materials m lade from sugar have been developed to destroy viruses on contact and may help in the fight against viral outbreaks.

This new development from a collaborative team of international scientists shows promise for the treatment of herpes simplex (cold sore virus), respiratory syncytial virus, hepatitis C, HIV, and Zika virus to name a few. The team have demonstrated success treating a range of viruses in the lab – including respiratory infections to genital herpes.

The research is a result of a collaboration between scientists from The University of Manchester, the University of Geneva (UNIGE) and the EPFL in Lausanne, Switzerland...

Novel Coronavirus Receptors show similarities to SARS-CoV, according to new analysis

Previous studies have shown how the SARS virus (SARS-CoV) interacts with animal and human hosts in order to infect them. The mechanics of infection by the Wuhan coronavirus appear to be similar.

The recent emergence of Wuhan coronavirus (2019-nCoV) has put the world on high alert for transcontinental transmission, reminiscent of the outbreak of SARS – also a coronavirus – in 2002-2003.

Decade-long structural studies by Fang Li of the University of Minnesota, et al. have shown how the SARS virus (SARS-CoV) interacts with animal and human hosts in order to infect them. The mechanics of infection by the Wuhan coronavirus appear to be similar...

Gut reaction: How Immunity ramps up against Incoming Threats

Image result for VIP directly regulates IL-22 production by ILC3s.
ILC2 and ILC3 activities oscillate during the active and resting phase at steady state in wild-type mice.

A new study has revealed how the gut’s protective mechanisms ramp up significantly with food intake, and at times of the day when mealtimes are anticipated based on regular eating habits.

Researchers from the Walter and Eliza Hall Institute found, in laboratory models, that eating sets off a hormonal ‘chain reaction’ in the gut.

Eating causes a hormone called VIP to kickstart the activity of immune cells in response to potentially incoming pathogens or ‘bad’ bacteria. The researchers also found that immunity increased at anticipated mealtimes indicating that maintaining regular eating patterns could be more important than previously thought.

With the rise in conditions a...
