After i had been studing for histology examp i tried to solved one nominclature dilema.Its about fibrocytes and fibroblast.  In my histology book is statment, that fibrocytes is special type of cell which can be differentiated to different cell types by specific occasion ( for example exposure to transcript factors).   Then fibroblast is cell of connective tissue. Its differentiated.  Why is differentiated cell named with blast (usually active type) istead fibrocyte (usually the differentiated one)?

The affix -blast means an immature cell, and -cyte indicates any cell. So how do we define if a cell is mature (-cyte) or immature (-blast)? How does this apply to odontoblasts and ameloblasts? Why are they not simply called odontocytes and amelocytes, respectively?  What are the criteria for using the affix -cyte versus -blast?

I've tried to search for this answer but found no proper explanation.  My previous ideas were...  1) It is not a point source, so the different points on a filament lamp may cancel out the light from other points on a filament lamp  2) It emits light rays at random (even though I've read this, I don't exactly understand what it means. Does it mean a single point on the filament may emit a photon one second and then the next second not emit anything?)  Are these reasons along the right lines? Could someone give a proper explanation as to why a filament lamp is an incoherent light source?

Wolverine has . He can .  Cut off Wolverine's finger. A new finger will be grown from his body, but the dismembered finger will not be grown back into a full body.  I want to know which types of cells are capable of regeneration to a full Wolverine and what decides it.  Something more: Blow up the body of Wolverine so that only his Adamantium skeleton is left.  Now, cut this skeleton into two equal parts using Antarctic Vibranium. Which part of the skeleton would regenerate to the full Wolverine?

I have a column of cells where each cell contains one of the following text values  Optimal Normal High-Normal Mild Moderate  Severe   I would like the cell colour to be a set depending on what the value in the cell is.  For Optimal I'd like a green and for Severe I'd like a red, and for the others I'd like a different colour in between.  How do I do that?

The occurrence of Heart cancer (similar, but not the same as Rhabdomyosarcoma) is extremely rare, about 1 per year according to . The reason for this rarity is explained to be the post-mitotic nature of cardiac muscles. Since they stop dividing early in the life cycle of humans and grow only by increasing in volume, they are very less prone to oncogenic activation events caused due to mutation as a result of an error in DNA replication (since they do not replicate their DNA as they do not divide).    Although I am not an expert in tumours and cancers, I think that malignant tumours in nervous tissue, i.e. brain tumours are fairly common, at least more common than heart cancer by several orders of magnitude. But neurons constituting these tissues are also permanently in interphase and hence do not divide.   Moreover, secondary malignancies in Brain and nervous tissue is also much more common than secondaries in heart (rare) though metastatic secondary tumours, I believe, do not require oncogenic transformations in the host tissue. A metastatic fragment of a primary malignancy transported by blood is enough to cause secondary tumours.  How then these tumours (primary and metastatic-secondary) are more common in nervous tissue than heart, though both are post mitotic, i.e. permanently in interphase?   and  are a few links which give some basics of cardiac malignancies, though they don't address the question quite directly.  provides possible explanation of lack of cancer due to high oxygen content.

I am finding an example to clearly differentiate and demonstrate the use of these two words. At the moment, I am relying more on my feelings to decide which word to use. Say I am writing an article that talks about a solution or framework, should I say:   It is a general solution to kill computer virus. It is a generic solution to kill computer virus.   I want to show that the framework is normal, does it job, nothing fancy and that's about it. If the two sentences above are correct, what are the perceived meaning of each sentence?

Why do we say there is an overall negative charge on the intracellular side of the plasma membrane at rest, and an overall positive charge on the extracellular side when both potassium and sodium are positively charged ions, and they are in relatively equal amounts on either side? It seems to me that both sides should be positively charged, and I can't get my head around it.

At school, we've been taught that human infants produce rennin/chymosin (which aids in the digestion of milk). More specifically, it is the peptic cells in the stomach which secrete prorennin, the inactive form of rennin (in addition to pepsinogen, the pepsin proenzyme).  User @another'homosapien's answer  also seems to concur with this (excellent answer by the way, I enjoyed reading it).  However  According to Mod. @AliceD's answer  (yet another excellent answer):     ...in humans there is only a chymosin pseudogene present...   Which (probably?) implies that humans (infant or otherwise) do not produce rennin.  I managed to get my hands on the Textbook of Medical Physiology (Guyton and Hall, South-Asian edition), and according to the book (Chapter Gastric secretions, page 406) peptic cells produce a large quantity of pepsinogen. There is, however, no mention of prorennin. I even flipped over to the Appendix at the back to look up "Rennin", but it turns out there is absolutely no mention of rennin in the book.    My questions,   Some sources claim that rennin is produced in human (infants). Is this true? Other sources claim that rennin is not produced in humans ( we have a pseudogene for it though). Is this correct (I mean the "rennin-is-not-produced" bit, not the "pseudogene" bit)? If rennin is produced in humans only during infancy, what stops it from being produced as we mature? (I'm asking this because every source I've seen that claims that rennin is produced in humans, explicitly states that is done so during infancy...which would suggest that rennin is not produced in adults)

I'm having a problem with LaTeX not hyphenating $\beta$-galactosidase, and the word as a result running off the page.  I have narrowed down the problem to a particular package, as a bare minumum LaTeX preamble with no packages avoids this problem.  Please help me to identify the offending package by process of elimination, and suggest a solution that retains the use of the package where possible.  \documentclass[a4paper,12pt]{article}  \usepackage[a4paper]{geometry}  \begin{document} Finally, all of the three antibiotics examined had a negative effect on $\beta$-galactosidase activity from the time they were introduced to the assay.  It is to be noted that chloramphenicol interferes with the 50S ribosomal subunit which negatively implicates peptide bond formation~\cite{chloram1962}, streptomycin interrupts the initiation stage of protein synthesis~\cite{strepto1968}, while rifampicin is an RNA-polymerase inhibitor~\cite{rifam1983}.  These results verify that both transcription and translation are needed for the gene product $\beta$-galactosidase to arise, which is probably not much more than a validation of the flow of genetic information in accordance with central dogma.  An interruption at the transcription or translational stage would prematurely or directly halt the production of $\beta$-galactosidase, in the two respective cases. \end{document}   Sample output:

I'm a huge fan of mathematical physics and I know what the formal definitions of those  two areas are, I've seen them. But I still get completely baffled when someone asks me to explain it simply. The difference is obvious to me, but I just can't seem to put it into words in a satisfying enough manner. So I'm asking you to help me...  What is the essential difference between  and ?  or if you prefer the rephrased version...  What was the motivation for introducing the name "mathematical physics" as a separate entity?  (It doesn't matter if you're one of those people who don't like labels, the thing is that we do have these two separated very often in academia.)

I would be very happy if someone can help me to find the answers for the following related questions.   Can one exon have many stop codons? Can protein synthesis happen, if the stop codon is at the beginning of the exon?

Third grade teacher here. I plan to teach students to distinguish between simple, compound and complex sentences — but only if I can demonstrate a clear and meaningful difference between the latter two!  Complex or Compound? Each sentence in the following pairs is similar to its partner.   All dogs are mammals, so huskies are mammals. All dogs are mammals, therefore huskies are mammals. I come bearing soup, for Kate is sick. I come bearing soup, because Kate is sick.   Are the sentences above complex or compound?   First, we need to decide whether each italicized clause is independent or dependent. To me, they all look dependent. If that is the case, there's not much need to teach about compound sentences. Is there a meaningful difference between the sentences in each pair that I am missing? (Are the FANBOYS as special as they'd like to think?)

Could you please clear up the meaning of these two words for me?  I don't understand this sentence:      Attributes introduced by RDFA have names. For example, property is one such attribute.

This question has haunted me for two years.    mentions :      A nerve is an enclosed, cable-like bundle of axons (the long, slender projections of neurons) in the peripheral nervous system. A nerve provides a common pathway for the electrochemical nerve impulses that are transmitted along each of the axons to peripheral organs.   Okay, my book also defines like that. But if the nerve runs only with bundles of axons, where then are their soma located?   They say nerves are formed of many axons bundled together. Now, if there are axons, there must be soma, but they do not form nerve &amp; hence are not present in nerve. So, where are they? Are they present at the beginning of the nerve?   Also, nerves communicate with each other. Books picture this as two neurons one above other; the above one sends impulse through its terminals to the dendrites of the neuron below it. So, how do these two neurons constitute a nerve?? After all, they now contain the cyton?? So, how do neurons one above other form nerve as they now contain the soma??   PLz explain.

I haven't been writing C for very long, and so I'm not sure about how I should go about doing these sorts of recursive things... I would like each cell to contain another cell, but I get an error along the lines of "field 'child' has incomplete type". What's up?  typedef struct Cell {   int isParent;   Cell child; } Cell;
