We revisited a classic study of morphological variation in the oldfield mouse (Peromyscus polionotus) to estimate the strength of selection acting on pigmentation patterns and to identify the underlying genes. We measured 215 specimens collected by Francis Sumner in the 1920s from eight populations across a 155-km, environmentally variable transect from the white sands of Florida's Gulf coast t...

Introduction It has been said that pigmentation of the skin is the most distinctive feature of Addison's disease (British Medical Journal, 1963) and that no other clinical feature is as useful diagnostically (Dunlop, 1963). Four cases are presented where no pigmentation was found. The difficulties in diagnosis are discussed and it is suggested that Addison's disease without pigmentation is comm...

The severity of inflammation in sympathetic ophthalmia is related to the degree of pigmentation, and the granulomatous response seems to be related to pigmentation. Eosinophilia is also associated with pigmentation, but this association appears to be fortuitous and is a result of the association of eosinophilia with severity of the inflammation.

Background: In todays world pigmentation of gingiva not just has an impact on esthetics but also creates psychological negativity.Esthetic awareness dental patients extended to include requests gingival color modification.Different treatment modalities which have been reported bur abrasion, scraping, partial thickness flap, cryotherapy, electrosurgery. However, pain and healing are the two draw...

this study was conducted to examine morphometric and meristic characteristics alongside pigmentation patterns of bream larvae, abramis brama orientalis, in four stages of larval development. morphological characters including total length (tl), standard length (sl), notochord length (nl), head length (hl), head depth (hd), eye diameter (ed) and mouth width (mw) were examined from hatching time ...

Near-infrared fluorescence imaging (NIRFI) and far-red fluorescence imaging (FRFI) were used to investigate effects of depilation-induced skin pigmentation and diet-induced background fluorescence on fluorescent signal amplitude and lymphatic contraction frequency in C57BL6 mice. Far-red fluorescent signal amplitude, but not frequency, was affected by diet-induced fluorescence, which was remove...
