  • In rare instances -- most often an XXY sterile male -- male cats will have both dark and light fur and skin. (thenest.com)
  • melanocytes
  • Excessive skin pigmentation is a result of abnormal production and deposition of melanin by the melanocytes. (thevictoriancosmeticinstitute.com.au)
  • The number of melanocytes present in our skin will determine our skin colour. (thevictoriancosmeticinstitute.com.au)
  • Specialized cells called melanocytes produce the melanin, which is then transported to other epidermal cells (called keratinocytes) that make up the majority of the skin. (emaxhealth.com)
  • Melanoma, a cancer of melanocytes, is the most deadly of the skin cancers, and its incidence is rising in the United States. (emaxhealth.com)
  • After showing that melanocytes in normal human skin express SOX9 under normal conditions, the investigators exposed normal human melanocytes to UV radiation, and compared the levels of SOX9 between radiated and non-radiated cells. (emaxhealth.com)
  • The researchers exposed normal human melanocytes and reconstructed skin samples to a chemical called forskolin, which stimulates the cAMP pathway. (emaxhealth.com)
  • Our reaction-diffusion system was developed based on biological data regarding human skin, pigmentary system and melanocytes life cycle. (ufrgs.br)
  • biological
  • While the biological cause of the selective event merits further investigation, we have demonstrated an unusual rapid case of selection for lighter skin pigmentation based on a recently introduced allele less that 2,000 years ago, the first case of pigmentation adaptation from migration in humans," the paper concludes. (phys.org)
  • CLSM images the skin by exploiting microscopic biological variations in refractive indexes. (spiedigitallibrary.org)
  • diseases
  • This skin problem can develop from overexposure to sun but also can be caused by numerous diseases. (livestrong.com)
  • Over the last decade, noninvasive optical in vivo spectroscopy through linear absorption, Raman, and fluorescence has shown potential in the diagnosis and characterization of human skin diseases. (spiedigitallibrary.org)
  • Finally, it can also be related to skin cancer or other diseases. (thenest.com)
  • humans
  • This is a "rare example of intense, ongoing adaptation in recent human history and is the first known example of adaptive gene flow at a pigmentation locus in humans," according to the paper published online in the Proceedings of the National Academy of Sciences on Dec. 10. (phys.org)
  • Skin colour is one of the most visible and variable traits among humans and scientists have always been curious about how this variation evolved. (medicalxpress.com)
  • It can be age-related, akin to the lightening of skin and graying of hair in humans. (thenest.com)

  • hemoglobin
  • The primary light absorbers in skin are hemoglobin and melanin. (spiedigitallibrary.org)
  • Traditionally skin redness is considered to arise due to locally elevated concentrations of hemoglobin, whereas skin pigmentation is attributed to melanin. (spiedigitallibrary.org)
  • Thus, deoxy-hemoglobin correlated moderately with the clinical erythema scoring on day 1 only, while it contributes significantly to what is clinically perceived as skin tanning on days 7 and 14. (spiedigitallibrary.org)
  • Application of pressure below the diastolic level increased deoxy-hemoglobin concentration as measured by DRS. This increase corresponded to a decrease of a "pigmentation" parameter (based on the L*a*b* scale) in a similar fashion that has been documented for increases in melanin concentration. (spiedigitallibrary.org)
  • Topical H 2 O 2 application reduced deoxy-hemoglobin levels as measured by DRS. This reduction coincided kinetically with a visible skin blanching. (spiedigitallibrary.org)
  • In this report we present compelling evidence that deoxy-hemoglobin significantly contributes to the skin color appearance. (spiedigitallibrary.org)
  • Blood pooling, expressed as increased deoxy-hemoglobin, can contribute to what is visually perceived as pigmentation. (spiedigitallibrary.org)
  • Deoxygenated hemoglobin (in the veins) - blue skin color is the combination of these four. (healthtap.com)
  • Individuals
  • Individuals who carry two copies of the lighter pigmentation gene are 14 percent lighter-skinned than the population average, the researchers said. (phys.org)
