  2. Perceptual control theory - Wikipedia

    en.wikipedia.org/wiki/Perceptual_control_theory

    Perceptual control theory (PCT) is a model of behavior based on the properties of negative feedback control loops. A control loop maintains a sensed variable at or near a reference value by means of the effects of its outputs upon that variable, as mediated by physical properties of the environment.

  5. Proximal tubule - Wikipedia

    en.wikipedia.org/wiki/Proximal_tubule

    The proximal tubule is the segment of the nephron in kidneys which begins from the renal pole of the Bowman's capsule to the beginning of loop of Henle.At this location, the glomerular parietal epithelial cells (PECs) lining bowman’s capsule abruptly transition to proximal tubule epithelial cells (PTECs).

  6. Distal convoluted tubule - Wikipedia

    en.wikipedia.org/wiki/Distal_convoluted_tubule

    The DCT is lined with simple cuboidal cells, the distal convoluted tubule cells, that are shorter than those of the proximal convoluted tubule (PCT). The lumen appears larger in the PCT than the DCT lumen because the PCT has a brush border (microvilli).

  7. Progenitor cell - Wikipedia

    en.wikipedia.org/wiki/Progenitor_cell

    Research on cancer biology focuses on the impact of progenitor cells on cancer responses, and the way that these cells tie into the immune response. [ 6 ] The natural aging of cells, called their cellular senescence, is one of the main contributors to aging on an organismal level. [ 7 ]

  8. Master mix (PCR) - Wikipedia

    en.wikipedia.org/wiki/Master_mix_(PCR)

    A master mix is a mixture containing precursors and enzymes used as an ingredient in polymerase chain reaction techniques in molecular biology. Such mixtures contain a mixture dNTPs (required as a substrate for the building of new DNA strands), MgCl 2, Taq polymerase (an enzyme required to building new DNA strands), a pH buffer and come mixed in nuclease-free water.

  9. Population genetics - Wikipedia

    en.wikipedia.org/wiki/Population_genetics

    Population genetics is a subfield of genetics that deals with genetic differences within and among populations, and is a part of evolutionary biology.Studies in this branch of biology examine such phenomena as adaptation, speciation, and population structure.
