Keloids were described by Egyptian surgeons around 1700 BCE, recorded in the Smith papyrus, regarding surgical techniques. [citation needed] Baron Jean-Louis Alibert (1768–1837) identified the keloid as an entity in 1806. [citation needed] He called them cancroïde, later changing the name to chéloïde to avoid
Minor genetic variations are found consistently in different geographic areas; thus, genetic analysis of Human polyomavirus 2 samples has been useful in tracing the history of human migration. [25] 14 subtypes or genotypes are recognised each associated with a specific geographical region. Three are found in Europe (a, b and c).
A colloid is a mixture in which one substance consisting of microscopically dispersed insoluble particles is suspended throughout another substance. Some definitions specify that the particles must be dispersed in a liquid, [1] while others extend the definition to include substances like aerosols and gels.
Hexatic state, a state of matter that is between the solid and the isotropic liquid phases in two dimensional systems of particles. Ferroics; Ferroelastic state, a phenomenon in which a material may exhibit a spontaneous strain. Photon molecule: Photons which are connected with each other, attracted by apparent mass while mediating energy transfer.
Intake of drugs that depress neurologic function may also lead to aspiration. The resultant granulomas are typically found around the airways (bronchioles), and are often accompanied by foreign body-type, multinucleated giant cells, acute inflammation, or organizing pneumonia. The finding of food particles in lung biopsies is diagnostic. [17]
Skin tags are thought to occur from skin rubbing against skin, since they are often found in skin creases and folds. [2] Studies have shown existence of low-risk human papillomaviruses 6 and 11 in skin tags, hinting at a possible role in their pathogenesis , [ 3 ] although a 2012 study found no association between skin tags and either low- or ...
The total number of distinct Egyptian hieroglyphs increased over time from several hundred in the Middle Kingdom to several thousand during the Ptolemaic Kingdom.. In 1928/1929 Alan Gardiner published an overview of hieroglyphs, Gardiner's sign list, the basic modern standard.
Poliomyelitis (/ ˌ p oʊ l i oʊ ˌ m aɪ ə ˈ l aɪ t ɪ s / POH-lee-oh-MY-ə-LY-tiss), commonly shortened to polio, is an infectious disease caused by the poliovirus. [1] Approximately 75% of cases are asymptomatic; [5] mild symptoms which can occur include sore throat and fever; in a proportion of cases more severe symptoms develop such as headache, neck stiffness, and paresthesia.
