I'm a researcher in neuroendocrinology

I'm interested in all that regards pattern recognition, time series analysis, rhythms etc.

My current research focuses in the exploration and modulation of the neuro-endocrine patterns that contribute to the generation of hormone pulsatility.

comment diameter = dia?
@WYSIWYG: it is about well defined scientific jargon, it is not a matter of personal preference.

comment Reference for writing an International journal in micro-biology/micro-organism field
Agree with the other comment. Choose a journal and then check their guidelines, they can vary a lot even in the same field. And this should maybe be migrated to Academia.SE

comment When can a virus modify DNA in every cell of a living organism?
Note that in the type of experiments you are referring to (for instance look for "in vivo optogenetics") you generally do NOT want to infect all of the neurons in the brain, but rather a very specific subpopulation. This is achieved by using various strategies, which essentially depend on the presence of specific DNA sequences in the virus or in the target neurons. Also, if you do this in adult animals, the virus will only infect cells around the site at which it has been injected.

comment Why doesn't human consumption of plants cause infectious diseases the way consumption of animals can?
The classical example of fungal toxins are aflatoxins, which are very nasty.

There is no scientific basis for blood-type diet. See skeptics.stackexchange.com/questions/189/… and skepdic.com/bloodtypediet.html

comment Why do I always close my eyes when someone takes a photo of me using a flash?
@kmm: it is definitely a good question. I am not sure how does the opthalmic branch of the trigeminal sense light... What is always reported is that the trigeminal is the afferent pathway and the facial nerve is the efferent pathway (which moves the eyelid), with some brainstem processing in the middle. Interestingly, the photic sneeze reflex (i.e. sneezing when looking at the Sun) is derived by activation of the same pathway. I am a bit busy at the moment, but I'll try to expand the answer later if I find a better explanation.

comment What happens if we continuously stimulate a mimosa plant?
Could you expand on the specific stimulus you are talking about? I am not familiar with the behaviour of mimosa plants...

comment Is there a realtime molecular clock within the genome to co-ordinate the developmental sequences in an embryo?
Ok, now I understand what you mean. In general when speaking about "molecular clock" one refers to a set of genes and their derived proteins that govern circadian rhythms and that indeed act as a "24h timer". See also my explanation here: biology.stackexchange.com/questions/2299/… . Now, although these genes are involved in circadian (~24h) rhythms, they possibly also have a role in shorter (<24h, ultradian) and longer (>24h infradian) rhythms, although this is still very much an unresolved question.

comment Is there a realtime molecular clock within the genome to co-ordinate the developmental sequences in an embryo?
You think it is difficult to believe that development is only timed by molecular events, but you are asking whether there is a molecular clock? Seems a bit contradicting... Anyway it has been shown that disruption of clock genes leads to developmental defects: for instance (these are just two random papers I found, but there is surely more) ncbi.nlm.nih.gov/pubmed/22884368 ncbi.nlm.nih.gov/pubmed/17963275

Does 23andme sequence the whole DNA? I thought they were only looking for specific SNPs. Anyway, maybe this can answer part of your questions customercare.23andme.com/forums/20881310-Maternal-Paternal-Line

comment Randomness in living systems
@Remi.b: don't get me wrong, I find the question very interesting. I think at the end it all comes down to the definition of "randomness" which one wants to use. Is a random event something that is too complex to predict? Or is it something even with infinite computing power we could never predict?

comment Randomness in living systems
I find your computer example inconsistent with the rest of the question. If you are not interested in randomness at the molecular/sub-mulecular level, then you can say that, as PRNG in computers, also biological processes are deterministic. You make a "random" choice between A and B because (as an extremely simplistic example) your neuron "A" fired more than your neuron "B"...

comment Is Diabetes sex linked disease
@Oreotrephes: sex-linked just means that it depends on some gene present on the sexual chromosomes (chromosomes X and Y), so that it is not passed equally in the progeny (e.g. a gene on the Y chromosome will not influence females, who are XX). I would also like to add that epigenetics plays a very important role in the development of diabetes.

comment Can rats pass on memories of a maze to their offspring?
Very interesting! I have not had the time to read through the article yet, so I do not know whether they address this, but I wonder what happens if then you expose those 4th generation birds to birds that sing normally. Who would they choose? A screeching one or a singing one?

comment Do body lotions enter into bloodstream of people? And how do they do it?
To complete, I would add that the issue here is that the skin is composed by a mix of hydrophilic (="water-loving") and hydrofobic (="fat-loving") layers, so a water-based lotion will pass easily through the former and much less easily through the latter, and the opposite is true for a fat-based lotion. PS: just a little note on your first sentence: lotions are not drugs, they are formulations, like a pill or a spray. You can use lotions as a formulation for drugs.

Surely they go in, that is the principle by which topically applied drugs work!

comment Botulinum Toxin
Denaturation is a naturally occuring process and it works pretty much like radioactive decay.... hmmmm.... no it is not. Radioactive decay is irreversible, denaturation is not, as renaturation can occurr.

comment What triggers DNA to produce proteins?
@Alan Boyd: I think the question is asking what environmental signals act to recruit TF to start transcription. For instance activation of membrane receptors and so on.
