Reply to comment by gerundive in A new biomaterial that can be injected intravenously, reduces inflammation in tissue and promotes cell and tissue repair. The biomaterial was tested and proven effective in treating tissue damage caused by heart attacks in both rodent and large animal models by giuliomagnifico
Interesting. Amazing. Fucked. Damned useful.

Reply to Study shows that regular coffee drinking (2 to 3 cups per day) is associated with lower systolic blood pressure (SBP), peripheral pulse pressure (PP), aortic BP and aortic PP, but with similar arterial stiffness by giuliomagnifico
Why is everyone reading this as coffee=good. It says lower blood pressure but similar arterial stiffness. It's the arterial stiffness that kills you, not the blood pressure. Blood pressure is normally a symptom of arteriosclerosis. This says coffee hides that symptom, but that only mask the underlying condition.

People in the future will look at us as barbarians for what we do to animals, and maybe we are, but it’s true to that without these methods, we may never gain this knowledge.

I was curious how animals such as rats, dogs, monkeys etc might be given heart attacks, and found the following, which may be of interest to others who are similarly curious.
"Myocardial infarctions (MIs) in rats were originally induced by the sequential administration of subcutaneous isoproterenol causing diffuse myocardial necrosis. Subsequent investigators used an electrocautery technique applied to the epicardial surface to induce small, focal infarctions. Soon thereafter, Pfeffer et al developed the rat coronary ligation model that became perhaps the most widely used heart failure and MI model in the decades to follow."
Apparently transgenic animals can also be used, bred to carry mutated genes so that they develop hypertension, hypertrophy and subsequent heart failure.

Stopped any caffeine two weeks ago for the first time in a long time. Anxiety has improved big time. Its crazy

Oooh! I loved Mrs Frisby and the Rats from NIMH! Is this a sequel?

I don't fear clowns, but generally I find them creepy.

How do we know this isn’t just the effect of people who were told not to drink coffee because of high blood pressure?

So the people doing this research have no ethical concerns? This is Dr. Moreau level "science."

Sounds like the sooner we plant native trees the better imo.

Italian study, so 100% it's espresso cups.

those are such obvious reasons
why did we have to waste money on a study?

Nothing says legit like getting published in Nature.
