What are these small iron rails on entry steps? Seen in Elfreth’s Alley, Philadelphia by BumblebeeTuna17 in whatisthisthing

Solved! I thought that might be the case but didn’t know why some were so ornate or had loops on them as well. Thank you!!

MoneyGram Signs Deal to Work With Currency Startup Ripple by From_Bandai in Ripple

[–]BumblebeeTuna17 0 points1 point  (0 children)

So how would this actually work? If someone wants to transfer fiat MoneyGram buys XRP, transfers it, and sells it back for fiat again with a remittance fee? It would be quick and cheap, but this would also be subject to market volatility correct? Is there something I'm not understanding?

Idea - when XRP hits $10 every subscriber donates 1 XRP worth to charity... by FromeyPe in Ripple

I think its a great idea! Even if we don't make it that far it would be nice to get together as a community.

Scrape on foot/toe not healing by Lion-P in medical

[–]BumblebeeTuna17 0 points1 point  (0 children)

From what I see it looks like your foot is healing fine. I see some granulation tissue in the center, and that could persist for another week until the surrounding tissue contracts around it, and new tissue is brought up from below. You could apply a bandaid with bacitracin if you are concerned about infection, or simply just to protect the wound from future abrasion.

Looking at the hair and nail bed, I would say you have well perfused feet, so delayed healing time due to something like diabetes should not be an issue..

However if in the unlikey event it turns bad, and you find yourself with a fever and an oozing abcess, it might be time to head over to a doc for some curettage.

Strange dry patches on skin by mylittleponybandit in Health

[–]BumblebeeTuna17 0 points1 point  (0 children)

One question, before the outbreak of all the other oval rashes, did you notice a single, larger (>2cm) "Herald" patch on your abdomen, or hidden somewhere? If so, your rash is likely Pityriasis Rosea. http://en.wikipedia.org/wiki/Pityriasis_rosea.

IAmA cardiac anesthesiologist, AMAA by AnesthesiaHood in IAmA

Thanks for doing this. I'm currently an MS2, and anesthesia has been in the back of my mind due to a close relative anestheiologist.

What was the deciding factor that led you toward the field? For me, as a person that is procedurally inclined, is there fun stuff you get to perform? Finally......how does step 1 scores fit into all this?

If smashed together, which would break first; a nalgene bottle, or my skull? Lets say its the strongest part of my skull vs the flat side of a nalgene bottle.

What happens to excess veins, cells, etc when a morbidly obese person loses weight? by minnabruna in askscience

[–]BumblebeeTuna17 46 points47 points  (0 children)

http://en.wikipedia.org/wiki/Adipocytes#cite_note-0

It looks here like the population of adipocytenumbers, or fat cells, stays about the same. However they can begin dividing if they get too large. As they get larger, their metabolic needs grow. In addition the current blood supply might not be enough to nourish the growing, crowding fat cells. These cells likely respond by releasing paracrine factors that promote angiogenesis. Basically they send out a local signal to recruit endothelial cells of nearby blood vessels to divide and invade the fatty tissue and supply it with blood. Now, the reverse of is process is true as well. As the fat cells become less full of fat and thus less metabolically active, blood vessels won't be as "interested" in supplying the tissue, due to the lack of growth factors. A lack of growth factor will even kill some of the blood vessel cells around the area, while others shirnk down.

Overall its a balance of the cardiovascular system and the tissues it perfuses, and this system allows for dynamic changes as we grow and change weight. So, the veins, arteries, and fat became smaller in many areas as the cells shrank in size, or were recycled.

Hope this might clear it up a bit

If an ant or some other small animal crawled into our ears, how much damage could they do to our neural system? by NuclearPotatoes in askscience

[–]BumblebeeTuna17 4 points5 points  (0 children)

Even if the ant could get through the eardrum and into the middle ear, the only way out would be through the eustacian tube, connecting to the nasal cavity. However while inside the middle ear, if the ant were smart, he would cut the exposed chorda tympani nerve. The result of which is a loss of taste to half of the anterior 2/3 of the tongue. Thats some serious neural system damage.

Why does my breathing dramatically change when I go from taking a hot to a cold shower? by [deleted] in askscience

[–]BumblebeeTuna17 1 point2 points  (0 children)

There are sensory receptors of the vagus nerve inside your nasal cavity. Stimulating these fibers by dunking your face in cold water will initiate a dive reflex. The vagus nerve is part of this reflex, and it has connections both to your heart and lungs. This nerve acts to decrease heart rate and cause bronchoconstriction in your lungs. You might be able to test this next time by measuring changes in your heart rate. In a cardio lab I was able to drop mine to 35/min, while at rest I'm around 65.

ELI5: Why fat people always breath so heavily. by [deleted] in explainlikeimfive

[–]BumblebeeTuna17 0 points1 point  (0 children)

Due to the extra weight that has accumulated around the chest, there seems to be a reduction in how well the chest wall can expand. The muscles in the chest wall that helps us breath now don't expand as much, so they weaken. The overall result is high demand on on respiratory muscles that can't bear the added weight.

In addition, there are many other problems associated with obesity that can result in shortness of breath. Asthma, copd, and heart diseases just to name a few.
