The blood–brain barrier (BBB) is one critical example of protection which prevents toxins and other adverse compounds from reaching the brain. [22] As the brain requires nutrient entry and waste removal, it is perfused by blood flow. Blood can carry a number of ingested toxins, however, which would induce significant neuron death if they ...
In some cases the level or exposure-time may be critical, with some substances only becoming neurotoxic in certain doses or time periods. Some of the most common naturally occurring brain toxins that lead to neurotoxicity as a result of long term drug use are amyloid beta (Aβ), glutamate, dopamine, and oxygen radicals.
Brain trauma or stroke can cause ischemia, in which blood flow is reduced to inadequate levels. Ischemia is followed by accumulation of glutamate and aspartate in the extracellular fluid, causing cell death, which is aggravated by lack of oxygen and glucose.
Known for their gut health and bone benefits, prunes are also great for your brain. Prunes are high in potassium and a source of vitamin B6 and copper, all micronutrients that contribute to normal ...
Toxic encephalopathy is a neurologic disorder caused by exposure to neurotoxic organic solvents such as toluene, following exposure to heavy metals such as manganese, as a side effect of melarsoprol treatment for African trypanosomiasis, adverse effects to prescription drugs, or exposure to extreme concentrations of any natural toxin such as cyanotoxins found in shellfish or freshwater ...
It has no known function for clostridia in the soil environment where they are normally encountered. It is also called spasmogenic toxin , tentoxilysin , tetanospasmin , or tetanus neurotoxin . The LD 50 of this toxin has been measured to be approximately 2.5–3 ng/kg, [ 2 ] [ 3 ] making it second only to the related botulinum toxin (LD 50 2 ...

Oxidative stress mechanisms in tissue injury. Free radical toxicity induced by xenobiotics and the subsequent detoxification by cellular enzymes (termination).. Oxidative stress reflects an imbalance between the systemic manifestation of reactive oxygen species and a biological system's ability to readily detoxify the reactive intermediates or to repair the resulting damage.
