Methanol is rapidly absorbed not only after oral ingestion but by inhalation or after cutaneous exposure and becomes oxidised in the liver to formaldehyde and to formic acid, metabolites which are more toxic than methanol itself and which inhibit mitochondrial ATP production. Histopathologically, circumscribed myelin damage behind the lamina ...

There are two different aspects to or drivers of thirst, osmolality and hypovolemia, with plasma osmolality elevation being the more potent stimulus of thirst. As stated by @arboviral (and supported by his link), not a lot is known about the mechanisms of immediate thirst satiety.

Satiety is divided into pre-absorption and post-absorption - the mechanism you're asking about is preabsorption satiety, which as you point out occurs long before the water can be absorbed into the bloodstream and appears to be remarkably accurate. The receptors and underlying mechanisms of pre-absorption satiety are not fully known but are thought likely to ...

After a lot of research, I've finally found an answer. In the case of humans, it is practically impossible. See this article from wikipedia: During gestation, the cells of the primordial gonad that lie along the urogenital ridge are in a bipotential state, meaning they possess the ability to become either male cells (Sertoli and Leydig cells) or female ...

Your question spans two activities of T-cells that are related to each other: migration and activation. T-cells that usually stay in lymphoid organs migrate to non-lymphoid organs with different mechanisms for each T-cell subtype. When migrated to non-lymphoid organ, the T-cells move through the organ looking for infected cells. Migration As you can see in ...

The calorie is a unit of energy. Our body uses the energy found in food to create ATP (a molecule that is handy to deal with energy) with the help of oxygen (that we breath in). ATP can then be used for plenty of tasks such as importing ions through a cellular membrane or more ultimately walking, talking, warming up your body, etc... Saying that some food ...

There are a lot of elements which can't be found, including Osmium. You can sort the table by other orders like name, symbol, mass, and others.

I took a 30 second look at the book you mentioned. The authors just made this up, just like 95% of the book. The authors are not wrong, they didn't want to write something useful and made a mistake, they're just bullshitting: They're making stuff up, letting it sound a tiny bit scientific and try to sell a lot of books. If you want to know more about ...
