    This aggressive behavior is sometimes marked by the acoustic sounds they produce. [16] The red-bellied piranha is not a migratory species [17]: 288 but does search for conditions conducive to reproduction during seasons of increased rainfall. [citation needed] Red-bellied piranhas are omnivores and primarily foragers.

  3. Piranha - Wikipedia

    en.wikipedia.org/wiki/Piranha

    [3] [29] Swimming near fishermen may increase the risk of attacks due to the commotion caused by struggling fish and the presence of bait in the water. [30] [31] Splashing attracts piranhas and for this reason children are more often attacked than adults. [29] Being in the water when already injured or otherwise incapacitated also increases the ...

    The authors additionally note that the fact that the measurements were taken on live animals may lead to underestimates caused by fatigue and stress. Furthermore, the measurements were restricted to the anterior bite-force, not including the potential of doubled bite-force along the lower jaw. This may result in forces between 2480 and 9498 Newton.

  5. Effects of parasitic worms on the immune system - Wikipedia

    All these fight a hyperactive immune response, reduce the inflammation throughout the body, and thus lead to less severe autoimmune diseases. [ 12 ] Osada et al. state that because parasitic worms may and often do consist of allergens themselves, the degree to which they pacify or agitate the immune response against allergens is a balance of ...

    Inflammatory demyelinating diseases (IDDs), sometimes called Idiopathic (IIDDs) due to the unknown etiology of some of them, are a heterogenous group of demyelinating diseases - conditions that cause damage to myelin, the protective sheath of nerve fibers - that occur against the background of an acute or chronic inflammatory process.

  7. Neurogenic inflammation - Wikipedia

    en.wikipedia.org/wiki/Neurogenic_inflammation

    Magnesium deficiency causes neurogenic inflammation in a rat model. Researchers have theorized that since substance P which appears at day five of induced magnesium deficiency, is known to stimulate in turn the production of other inflammatory cytokines including IL-1, Interleukin 6 (IL-6), and TNF-alpha (TNFα), which begin a sharp rise at day 12, substance P is a key in the path from ...

  8. Systemic inflammation - Wikipedia

    en.wikipedia.org/wiki/Systemic_inflammation

    Chronic systemic inflammation (SI) is the result of release of pro-inflammatory cytokines from immune-related cells and the chronic activation of the innate immune system.It can contribute to the development or progression of certain conditions such as cardiovascular disease, cancer, diabetes mellitus, chronic kidney disease, non-alcoholic fatty liver disease, autoimmune and neurodegenerative ...

  9. Chronic stress - Wikipedia

    en.wikipedia.org/wiki/Chronic_stress

    Prolonged stress can disturb the immune, digestive, cardiovascular, sleep, and reproductive systems. [17] For example, it was found that: Chronic stress reduces resistance of infection and inflammation, and might even cause the immune system to attack itself. [27] Stress responses can cause atrophy of muscles and increases in blood pressure. [28]
