The first recorded observation of a cytolethal-distending toxin was in 1987 in a pathogenic strain in E. coli isolated from a young patient. [3] Later that year, scientists W.M. Johnson and H. Lior published the journal article "Production of Shiga toxin and a cytolethal distending toxin (CLDT) by serogroups of Shigella spp." in Microbiology Letters. [1]
Excitotoxicity can occur from substances produced within the body (endogenous excitotoxins).Glutamate is a prime example of an excitotoxin in the brain, and it is also the major excitatory neurotransmitter in the central nervous system of mammals. [14]
It causes toxic shock syndrome (TSS) by stimulating the release of large amounts of interleukin-1, interleukin-2 and tumor necrosis factor. In general, the toxin is not produced by bacteria growing in the blood; rather, it is produced at the local site of an infection, and then enters the blood stream.
Biological Toxins such as Diphtheria toxin [18]; Radiation Therapy is known to cause radiation-induced heart disease (RIHD) [19] These agents can lead to varying degrees of cardiotoxicity, and their effects may be dose-dependent and influenced by individual factors such as pre-existing cardiovascular disease and genetic predispositions that can foster greater sensitivity to any cardiac damage.
Weight fluctuations of five pounds are more are uncommon among men. Experts explain common sudden weight gain causes, what to do, and when to see a doctor. 12 Common Causes of Sudden Weight Gain
The term haemotoxin is to some degree a misnomer since toxins that damage the blood also damage other tissues. Injury from a haemotoxic agent is often very painful and can cause permanent damage and in severe cases death. Loss of an affected limb is possible even with prompt treatment.
Weight gain is an increase in body weight. This can involve an increase in muscle mass , fat deposits , excess fluids such as water or other factors. Weight gain can be a symptom of a serious medical condition.
Functional hyperaemia is an increase in blood flow to a tissue due to the presence of metabolites and a change in general conditions. When a tissue increases its activity, there is a well-characterized fall in the partial pressure of oxygen and pH, along with an increase in partial pressure of carbon dioxide, and a rise in temperature and the concentration of potassium ions.
