It's very much an issue of individual susceptibility - and bad luck. Also, the meninges aren't _that_ well shielded from the environment as most ppl think. Especially in the olfactory tract, they're quite exposed, only a thin membrane separates them from the airways. So an infection acquired in...

Late but... Both. The pressure is omnidirectional. As mentioned above, the Riva-Rocci-BP-method doesn't measure pressure directly, but by compressing and thus occluding, later obstructing the upper arm arteries. This causes turbulent flow behind the narrowed part is auscultated, either using a...

Wikipedia will tell you the core facts, no use reinventing the wheel...

Up to there it's OK. But Bilirubin isn't hepatotoxic, it's neurotoxic. Death is a rather rare final effect of Rh-incompatibility reaction - blindness and brain damage, however are quite probable... ...unless there's good neonate care available (ICU and/or dialysis - the latter with knowledge...

[Emphasis mine] Still uncorrected (as of 20 Nov 2022) Where's that "No controversy"? That's the "Comparing-apples-with-oranges"-[insert preferred expletive] stuff that's being intentionally used and amplified by our anti-anything-meaningful movement over here*... ...getting gullible people...

Quoted from the unquotable Qoute in Berkeman's post above: “Every day, you need to make the decision that you want to quit using your drugs, whereas, with a vaccine, you only have to make that decision once in a while,” said Therese Kosten, professor of psychology at the Univerity of Houston."...

IMHO the question is imprecise... Above are plenty of answers for "Does a female cell have more DNA than a male cell?", where the answer is "Yes... ...generally it does." ---begin-qualified-nitpicking------------------------------------- - First caveat here: Not included are 45 X0 genotype...

It would be helpful to have something published in an open-access journal... Assuming that the handicap principle model is still in use (and the Grafen paper being cited 1750 times, one should presume so...) there should be some other publication available, or maybe a paper or three where the...

The muscles weren't known to me either... ...but I got my diploma in 1997, so... IMHO&Guesstimation they might rather - either have an iris-like effect (increasing photosensitivity, not by opening the shutter, but compressing and thereby deforming the photoreceptor cone) - or slightly...

...not based in reality. The mass of the forearm is 3kg-ish, and the length is 40cm-ish.

Depends on where exactly (i.e. at which organ) you look. Vessels in organs relevant to sympathicus-associated stuff - fight, flight, fright - will get dilated. Like e.g. heart and lung. Might be true for spinal motoneuron vessels, too... Intestinal perfusion, however, is reduced, as is the...

Is it from a specialty textbook? (like e.g. neurology?)

"...can be..."? Could you please continue the quote or elaborate? Certain vessels can get dilated by catecholamines - e.g. coronaries, pulmonary vessels (IIRC). Which does make sense, physiologically. Also I seem to remember that, while on the one hand the vessels are constricted, they get...

But the blood vessels are elastic... ...and do change their diameter passively as well as actively (that's what the lamina muscularis of the vessel wall does...) for regulation purposes. Hence I repeat as recommended above: Grab a textbook...

Ummm... Many - if not most - of those sepsis deaths (often ascending urosepsis) happen in the course of hospital treatment. Often in patients that are very sick to begin with, venerable, have an immune disorder, or are temporarily immunocompromised (like during oncologic chemotherapy or a...
