High oxygen concentration can be deleterious; it can induce oxidative damage. The systemic blood circulation would supply oxygen to the "oxygen-deprived" lung. Moreover, Mycobacteria can survive in anaerobic conditions. And what if both lungs are infected? There are many flaws in the proposed therapy. Adding this point from one of the comments below: ...

One of the most common toxins in mouldy food/bread is aflatoxin. The exposure to high amount of aflatoxin can lead to acute aflatoxicosis with fulminant hepatic failure and even death. While mild exposure to aflatoxin could be asymptomatic, it is better not to take a chance considering possible complications (cit. from the link above): Aflatoxins ...

The accepted answer is correct but I would like to point out a misunderstanding that has to underly the idea that this would work: In reality lungs aren't a magical one-way gate for the various gases. Lungs do not extract oxygen from the air, they permit oxygen exchange between the air and the blood. Since the air normally has a higher oxygen level than ...

Babies are bacteria-free at birth. The meconium (the first stool) contains no bacteria if secured early enough. Meconium is a sterile mucilaginous material that accumulates in the fetal intestine and is expelled soon after birth. It contains secretions of intestinal glands, gut constituents (proteins, bile acids, fatty acids, and steroids), and ...

Sugar (be it sucrose, glucose, fructose or honey) does not have emetic properties in any concentration, unless there is a personal (and highly individual) psychological adverse reaction to sweet substances. Sugar is not a local gastric irritant (like dishwashing detergent, or syrup of ipecac, copper sulphate, zinc sulphate; yellow mercuric sulphate, ...

What a great question! I'm sorry to add another blow to your theory... but... Even if oxygen depletion would be effective, treating the lungs alone is not good enough. True enough, Mycobacterium tuberculosis bacteria usually attack the lungs, but TB bacteria can also attack other parts of the body such as the kidney, spine, and brain (Fig. 1). If not treated ...

It is just a way of highlighting your search term. If you search M00115+C03722, you will see C03722 in red.

In germ cells telomerase enzyme is active and elongates telomeres, so youngsters are not born older than their parents due to telomeres. Still, they do receive mutations, accumulated by their parents' germ-line cells, i.e. eggs and sperm. Most of the mutations occur upon division of the cell. Egg cells don't undergo many divisions - they are created in the ...

The place where the cord was cut do not stay with us - it falls in a week +- after the birth, while the umbilicus is the only visible natural scar formed by natural processes, not by gynecologists: Multiple sources say the umbilicus has a scar tissue in it. After birth the umbilicus is the only naturally formed visible scar on the body. Br J Plast ...

Here's a bit of additional information (Although there's an answer from Ilan that satisfied you.) Is it the mould itself that makes us sick or is it something that the mould is releasing? What are the mechanisms that cause us to feel sick after eating mouldy food? The USDA says that there can also be bacteria along with the mould on the ...

The most evident problem I can see for this TB treatment is that mycobacteria can survive without oxygen. Latent TB (a person is infected but doesn't have active TB) is one of the major problem in the treatment of TB and one-third of the world's population has latent TB! (http://www.who.int/mediacentre/factsheets/fs104/en/). A new TB treatment can only be ...

Our Unique Microbial Identity (Gilbert 2015) suggests that the gut microbiome is shaped and stablized during infancy and tends to restore equilibrium if it is disturbed later in life. Antibiotics temporarily change the composition of the gut microbiome (by suppressing the growth of certain groups of bacteria more than others), but it tends to drift back to ...

Xenon. It is like an ideal anaesthetic. See here. Xenon is an interesting anesthetic as it appears to lack negative inotropicy and vasodilatation, giving great advantages to both patients with limited cardiovascular reserve or those who require hemodynamic stability. It has low toxicity and is not teratogenic. Xenon gives rapid induction and ...

The phenomenon you described as "my eyes seem to adjust" is a particular case of accommodation - adjustment of the dioptric power of the crystalline lens to the object's distance. When you place a lens before your eye, any object seen through this lens will initially appear at a different distance (and of different size of course) and will be blurred at ...

Bernoulli's principle can be a little tricky when applied to the cardiovascular system, but it still holds true across the entire system. You mention a good point that the relationship doesn't seem quite right at the aorta or arteries, because of the constant fluctuation of pressure between systolic and diastolic without a significant change in diameter of ...

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 ...

We can only observe correlations Let's just talk about statistics. You can see a correlation between two things only if there is variation for these two things. It therefore, make no sense to look at a single trait that has no variance and ask "is it genetically coded?". The only thing that makes sense is to understand what variables explain the observed ...

Short answer As far as I am aware, neurotoxic effects of chronic excitatory stimulation are not prevented by receptor trafficking. Background I think the question assumes that 1) neural damage related to continuous activation (excitotoxicity) is preventable by 2) the dynamic regulation of receptor numbers on the neuronal membrane. As far as I can see, ...

In principle, many neurotransmitter receptors work as ion channels and the actual mechanism of signalling involves allowing the influx/efflux of calcium, potassium, magnesium, etc. A good example of this is the acetylcholine receptor. Presumably, if the cell retained the same number of receptors even in the presence of abundant ligands, the cell would flood ...

My understanding is that these statistics show the coverage for each KEGG Module in the particular phylogenetic group. For example, M00001, is found in 275 of the eukaryotic organisms in KEGG (which represents 90.5% of the eukaryotes in KEGG). The same logic applies for other groups. An quick example demonstrating this hypothesis, done with the Protists ...

The quotes in the question provide incomplete information at best. Let's focus on the nitrogen (N) that comes from protein, ignoring for now how metabolism differs among amino acids. We'll assume for simplicity that liver function is OK so that the urea N production rate is a reasonable measure of protein N degradation rate (say in units like moles of N per ...

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) ...

Propofol: a widely used i.v. anesthetic with GABA agonistic properties. It has to be given continuously i.v. When stopped, effects wear off in minutes, and recovery is without serious side effects and little nausea. Induction is quick (minutes or less) since it is administered i.v. Aminophylline (theophylline ethylenediamine), an adenosine receptor ...

TL;DR : Food gives the human body much more than simply vitamins & minerals. A healthy diet is essential to overall healthiness, not just this one aspect of it. Micronutrients The component you're asking about - vitamins & minerals - are referred to as "micronutrients", and is only a quarter or so of what the body needs. Micronutrients are the ...
