I think there are several things that keep Bernoulli's principle from being straightforwardly applied. First, Bernoulli's principle would help us calculate the pressure exerted by the blood on the walls of the vessels, but that's not what blood pressure measures. Blood pressure measures the amount of force that has to be applied to stop the blood from ...

I don't think that there is a one-size-fits-all answer to this question. There are different types of arrest and there might be different triggers depending on the epithelial cell type. Even in the cited Hammond et al paper, note that the effect of serum is not an immediate arrest. Human mammary epithelial cells (HMEC) could already go through 3 to 4 ...

The key thing is this: yes, the thymus involutes at puberty but that doesn't halt thymopoiesis. The thymus continues to produce naive T lymphocytes throughout our lives (even up to 70 years of age-see references) albeit at a very reduced rate. This mechanism is very important for example in HIV-infected individuals who are still able to repopulate their ...

This study in 1984 suggests it's a bad idea and other sites have said eating ants is for weight loss. The abstract says that it goes into detail about the problems associated with eating ants as well as their low nutritional value. So I believe the answer is no. You could not survive long term on a diet of only ants.

A few points, I'll expand on this later and add references if I have time: The thymus starts degenerating at puberty but continues to function in thymocyte maturation for decades, albeit at a lower level Many mature T cells can live for years Through homeostatic proliferation, peripheral T cells maintain their population size Immune surveillance generally ...

@Remi.b I think we can do better than 1962. Let's fast-forward here to 2014, in the post-genomic era. I think this paper provides some data relevant to your query: Possible mechanisms for Chromothripsis .

The "proper" term to use in a case of growth retardation in children is "failure to thrive", abbreviated as FTT. Celiac disease is one of the most common Organic endogenous (genetically based) FTT syndromes. The main cause of FTT in pediatric celiac patients is malabsorption. In a case of insufficient vitamins and nutrients absorption the child will (have) ...

During embryogenesis at the level of an atrioventricular canal there is so called endocardial "cushion" tissue. This tissue bulges to the left side more than it does to the right and contribute to the fusion of the valvular ring to a one leaflet, while from the remaining part of the ring develops the second leaflet: AVEC = atrioventricular endocardial ...

Short answer One way to distinguish between the olfactory and gustatory system in fish is by their anatomical differences. For example, olfactory receptors are clustered in the nasal region, while gustatory receptors are scattered in the head region and beyond. In turn, olfactory information is sent via a single cranial nerve to the brain, while the ...
