Time to get the toothbrush out and brush for longevity!

For decades, research has suggested a link between oral health and inflammatory diseases affecting the entire body — in particular, heart attacks and strokes.

The results released today from a randomized trial of a novel plaque identifying toothpaste, (Plaque HD®), show statistically significant reductions in dental plaque and inflammation throughout the body. Inflammation throughout the body is accurately measured by high sensitivity C-reactive protein (hs-CRP), a sensitive marker for future heart attacks and strokes. These results, published today online ahead of print in the American Journal of Medicine, with an accompanying editorial by the editor-in-chief, show that Plaque HD®, produced statistically significant reductions in dental plaque and inflammation throughout the body as measured by hs-CRP.

Humanized organs in gene-edited animals is one potential way medicine can deal with the demand for transplant organs.

One potential avenue for research and to help solve the organ shortage is to modify animals to be closer matched to humans in order to have organs capable of being used for transplant. This short paper is an interesting primer into the subject and touches upon the technical and ethical concerns involved here.

It is one possible solution to the problem, however, 3D bioprinting increases in sophistication and other methods are also being developed that would render this approach needless. Still this is an interesting insight into regenerative medicine and one possible path research might take.

A recent newspaper article under the headline “High street eye test can provide early indication of dementia” highlighted yet another complex connection between the eye and the brain.

This important eye-brain interface is still being researched and many disciplines are now working together to make fresh findings. But while most of us know that regular physical activity and eating healthily can help maintain or improve our well-being, few are aware of the importance of feeding our eyes with the right kind of light. Indeed, not experiencing the right quality and quantity of light could have adverse effects on hormonal changes, sleep patterns and may even be linked to obesity.

Novel treatments for neurological diseases might be possible with a flexible mesh that can prod individual brain cells.

Could we see this technology offered via subscription as the a new home screening method to check for cancerous polyps or cells in the stomach, colon, or esophagus?

The human intestine is a nearly 8-m-long cache of bacteria, both good and bad. When disease-carrying microbes colonize different sections of the gut, they can cause problems like inflammation and diarrhea. Researchers have now developed tiny, self-propelling, biocompatible robots that could deliver drugs or imaging agents to a targeted section of the intestine (ACS Nano 2016, DOI: 10.1021/acsnano.6b04795). When swallowed, the devices pass through the stomach, travel a preset distance, and embed themselves in the intestinal lining.

A team led by Liangfang Zhang and Joseph Wang of the University of California, San Diego, created 15-µm-long, 5-µm-wide hollow cylinders made of gold and poly(3,4-ethylenedioxythiophene). They filled the tubes with magnesium particles and a fluorescent dye as cargo and then coated them with a pH-sensitive methacrylate-based polymer. The methacrylate coating protects the tubes from the acidic gastric fluid in the stomach, but starts to dissolve in the neutral pH intestinal fluid. By tuning the coating’s thickness, the researchers can control how far the devices travel via natural gut movement before the coating dissolves completely; thicker coatings last longer.

Spark Therapeutics is within striking distance of a landmark green light from the FDA for its treatment for certain forms of blindness.

In Brief:

• Scientists have found a way of reactivating genes in mice to continue neuron growth.
• The development could be key to helping patients with paralysis and neurodegenerative diseases.

NAD+ therapy can supposedly increase your energy, focus, and metabolism, improve your cardiovascular health, and help you detox from alcohol and drugs. All this, of course, sounds incredibly unlikely—so I thought I’d see for myself.
