Gel that repairs heart attack damage could improve health of millions

https://www.theguardian.com/society/202 … h-millions

The study is being presented at the British Cardiovascular Society conference in Manchester.

British researchers have developed a biodegradable gel to repair damage caused by a heart attack in a breakthrough that could improve the health of millions of survivors worldwide.

Until now, when cells have been injected into the heart to reduce the risk of heart failure, only 1% have stayed in place and survived. But the gel can hold them in place as they graft on to the heart.

Re: Medical Science Potpourri

man-made messenger ribonucleic acid (mRNA) ph wait that is the covid recipe...

so what is "Stemin and YAP5SA"

Stemin was found to activate stem cell-like qualities in the cardiomyocytes in trials conducted in tissue culture dishes and on live mice, whereas YAP5SA enhanced organ development and replication. The club has referred to the procedure as a "game-changer."

Scientists develop greener, more efficient method for producing next-generation antibiotics

https://www.eurekalert.org/news-releases/960062

An international team of researchers has developed a method for altering one class of antibiotics, using microscopic organisms that produce these compounds naturally.

Published  in Nature Chemistry, could lead to more efficient production of antibiotics that are effective against drug-resistant bacteria.

Cold Plasma

Nonthermal plasma is the mercury-vapor gas within a fluorescent lamp, where the "electron gas" reaches a temperature of 20,000 K (19,700 °C; 35,500 °F) while the rest of the gas, ions and neutral atoms, stays barely above room temperature, so the bulb can even be touched with hands while operating.

Re: Medical Science Potpourri

Well, I like this.  It really is useful if other places do some different flavor of space research:

The science of moon hopping

This has caused me to wonder about the difference between arms and other parts of the body such as spine and legs.

We apparently need to stress many bones with static mass and also inertia reversals to keep them strong.

But I am not so sure this is true in the same way for arms.

What is the mechanism for arms?

Does the body just do a guesstimate for arms based on other bones such as perhaps legs experiences?

If one arm as stressed for a period of time more than the other, does the arm greater stressed show bone differences from the lesser stressed arm?

So, what is the signal and the source of the signal that tells the body what to do with bones?

Done.

New Zealand was considered rabies free until now

Person dies of rabies in Auckland in first known New Zealand case.

A person has died of rabies in Auckland in what health authorities say is the first known case of the disease in New Zealand.
https://www.rnz.co.nz/news/national/487 … aland-case

https://pubmed.ncbi.nlm.nih.gov/32089431/
"Currently, Pacific Oceania is free of rabies"

How long does rabies last on a dead animal?

https://catsndogs-answers.com/how-long- … ead-animal
Live rabies virus will not survive for more than 24 hours in dead animals when temperatures reach 70oF. However, the virus will sur- vive for extended periods at low or freezing temperatures.
