comment Is a raised baseline between T and QRS normal in any ECG lead?
@Raoul I fully agree with you (and don't think your previous comment was rude in any way). At the time of this question we already had a clear site guideline stating that no medical advice can be given or sought here.I understood the question so, that it is asked about usual finding on ECG, rather than "normal" in the meaning of "healthy". Hence is my answer.

@Raoul The answer is in no way medical consultation, especially for an acute medical problem, as stated in the site rules. The question asked is different from your answer.

comment Ultrasound during pregnancy
Ultrasound is just another techniques for medical imaging and it is very common to use radiation for imaging. Therefore the notice that this is not ionizing radiation might be important in this context. Besides, radiation is not limited to particles emission only and can also be emission of waves, that ultrasound actually is.

comment What is the concentration of ATP in an average cell?
The concentration of ATP depends strongly upon cell type, its current activity (for muscle, neuronal and secretorial cells). Besides, the local concentration of ATP in certain cell areas (mitochondria, near myosine heads, near membrane, in synaptic vesicles) might be orders of magnitude higher than that in other parts of cytozole.

Muscle cells generally need much more ATP than any other cell in order to to relax. The concentration in other cells (for example neurons) can differ significantly from these values.

comment Total amount of CO₂ / Oxygen in Bloodstream in Humans
This is little bit uncommon to use physical units for blood oxygen. Normally one just cares for the oxygen bound to haemoglobin, and doesn't consider the diluted oxygen. And trying to use your numbers I come to 0.8232 mole, that seems to be incorrect too...

comment Mechanism of syndesmophyte growth in AS
Not only symptomatoc, any inflammation (including the idiopatic one) would do. There are many reasons for hypoxie here: decreased blood flow rate, swelling etc.

You might find the following question helpful, but (replying to the duplicate flag) I don't think that these questions are exact duplicates...

Your English is not at all bad, I just wasn't sure what you mean and wanted to ask before I correct the title of your question. My native language is Russian, by the way, so don't take my English for "granted" :-)

comment What was the reason for some plant and animals to become giant in course of evolution?
The wording of your question is somewhat obscure. Do you mean "what was the reason for some plant and animals to become giant in course of evolution?" or probably "What are the advances and drawbacks of being a giant plant or animal organism?"

It would be nice if you could add some references to your question.

I am preparing an answer for your question, but it requires some literature research and takes time.

comment What effect does ambient temperature have on the cardiovascular system?
Your question mismatches your description: as long as you weren't jogging naked outside your body wasn't actually exposed to cold (and provided good warmth insulation by your clothes there wasn't need for excessive heat production). So, are you interested in considering your personal case or an abstract case of people running naked in cold environment? :)

comment Is there a correlation between muscle fibers and body types?
Body type is something about your constitution. I would probably formulate the question differently to ask for correlation between muscle types and physical strength/endurance, for there is some known correlations here (as @Amanda mentioned in her comment).

comment How exactly does long-term tension (over months) build up in the ligaments, tendons, muscles?
So, do I understand right that you mean massage by "tension"? Not static tension or something similar?

comment How do cockroaches resist the effects of ionizing radiation?
@MartaCz-C I use the words "humoral and cellular" in their direct meaning here, rather than referencing to the parts of adaptive immune system: this usage is acceptable and can be found in many research papers on insects (example). But thank for your suggestion, I will edit my answer.

comment Is it correct that the body only responds to the most painful stimulus?
@RoryM Not every input leads to the formation of a dominant center, the input has to fulfill certain criteria -- and if those are met then every input (cold, burn etc.) can do it. Pain is an example where it is true in most cases due to the nature of this input, but Ukhmomsky showed also other inputs in his experiments on dogs.

@RoryM I don't thinkg so, this is either our project or biostart.SE, rather the ours.

comment Is it correct that the body only responds to the most painful stimulus?
@yamad In Russian physiology this theory is considered to be proved. There is a classical book by Ukhtomsky (last edition was published in 2002) which describes his experiments with dogs which were used to prove the theory. There are numerous publications mentioning dominance principle in pubmed, but they are mostly in Russian.
