  2. Keloid - Wikipedia

    en.wikipedia.org/wiki/Keloid

    Keloids tend to have a genetic component, which means one is more likely to have keloids if one or both of their parents has them. However, no single gene has yet been identified which is a causing factor in keloid scarring but several susceptibility loci have been discovered, most notably in Chromosome 15.

  3. List of particles - Wikipedia

    en.wikipedia.org/wiki/List_of_particles

    Elementary particles are particles with no measurable internal structure; that is, it is unknown whether they are composed of other particles. [1] They are the fundamental objects of quantum field theory. Many families and sub-families of elementary particles exist. Elementary particles are classified according to their spin.

  4. List of states of matter - Wikipedia

    en.wikipedia.org/wiki/List_of_states_of_matter

    The particles are held very close to each other. Amorphous solid: A solid in which there is no far-range order of the positions of the atoms. Crystalline solid: A solid in which atoms, molecules, or ions are packed in regular order. Quasicrystal: A solid in which the positions of the atoms have long-range order, but this is not in a repeating ...

  5. Hypertrophic scar - Wikipedia

    en.wikipedia.org/wiki/Hypertrophic_scar

    A hypertrophic scar is a cutaneous condition characterized by deposits of excessive amounts of collagen which gives rise to a raised scar, but not to the degree observed with keloids. [1] Like keloids, they form most often at the sites of pimples, body piercings, cuts and burns. They often contain nerves and blood vessels.

  6. List of quasiparticles - Wikipedia

    en.wikipedia.org/wiki/List_of_quasiparticles

    Underlying particles Anyon: A type of quasiparticle that occurs only in two-dimensional systems, with properties much less restricted than fermions and bosons. Biexciton: A bound state of two free excitons: Bion: A bound state of solitons, named for Born–Infeld model: soliton Cooper pair: A bound pair of two electrons electron Bipolaron

  7. Wound healing - Wikipedia

    en.wikipedia.org/wiki/Wound_healing

    Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.

  8. List of skin conditions - Wikipedia

    en.wikipedia.org/wiki/List_of_skin_conditions

    The skin weighs an average of four kilograms, covers an area of two square metres, and is made of three distinct layers: the epidermis, dermis, and subcutaneous tissue. [1] The two main types of human skin are: glabrous skin, the hairless skin on the palms and soles (also referred to as the "palmoplantar" surfaces), and hair-bearing skin. [3]

  9. Colloid - Wikipedia

    en.wikipedia.org/wiki/Colloid

    Various types of colloids are recognised: inorganic colloids (e.g. clay particles, silicates, iron oxy-hydroxides), organic colloids (humic and fulvic substances). When heavy metals or radionuclides form their own pure colloids, the term " eigencolloid " is used to designate pure phases, i.e., pure Tc(OH) 4 , U(OH) 4 , or Am(OH) 3 .
