Smell as evidence of disease has been long used, dating back to Hippocrates around 400 years BCE. [1] It is still employed with a focus on volatile organic compounds (VOCs) found in body odor. [ 2 ] VOCs are carbon-based molecular groups having a low molecular weight, secreted during cells' metabolic processes. [ 3 ]
Similarly, humans have been seen to distinguish age-related information from body odor, particularly relating to odors of those of old age. In a study determining if there is a difference between the body odor of individuals of various ages, three groups were studied: those aged 20-30, aged 45-55, and aged 75-95, corresponding to young age ...
However, a 2007 study found schizophrenia patients to have reduced olfactory sensitivity to TMHA, possibly indicating sensory habituation; the decreased ability to smell the substance due to the presence of the substance as a constant component of subjects' own sweat and body odor. Furthermore, the researchers noted a positive association ...
Sweat and body odor are typically thought to go hand in hand, but experts say it's a little more complicated than that. Sweat alone doesn't have a smell, according to Harvard Health.
A fish-like body odor can result from extreme excess consumption of TMA precursors such as choline, carnitine and betaine (usually unobtainable via regular dietary intake, it requires high levels of supplement intake). 900mg of trimethylamine, [34] 8g-20g of choline, [35] 3g of carnitine [36] or 20g betatine [37] has been known to cause ...
Sickle cell disease is a group of inherited blood disorders, caused by a genetic abnormality in the oxygen-carrying protein haemoglobin found in red blood cells. [57] Under certain circumstances, this leads to the red blood cells adopting an abnormal sickle -like shape; with this shape, they are unable to deform as they pass through capillaries ...
The symptoms of blood agent poisoning depend on concentration and duration. Cyanide-based blood agents irritate the eyes and the respiratory tract, while arsine is nonirritating. [2] Hydrogen cyanide has a faint, bitter, almond odor that only about half of all people can smell. Arsine has a very faint garlic odor detectable only at greater than ...
According to Kukushkin, the memories stored in non-brain cells in other parts of the body are memories strictly related to the roles that those specific cells play in human health. Thus, he detailed:
