Faces each have distinct pigmentation as well as shape, which suggests that both cues may play a role in the perception of faces. However, there is a common implicit assumption that pigmentation cues are relatively unimportant, and so the role pigmentation plays in face perception has gone largely unexplored. This thesis is a systematic investigation of the role of pigmentation in face recognit...

There have been few previous studies of the kinetics of pigmentation following ultraviolet B (UVB) exposure, and these have included only fair-skinned persons. The current study investigated pigmentation increase to steady state and fading in 12 Scandinavians and 12 Indians/Pakistanis. Over a period of 3 weeks the subjects were UV-irradiated 6 times on the right side of the back and 12 times on...

nonea medik. is a genus of the boraginaceae tribe boragineae, with approximately 35 species worldwide. examination of their palynological characters supported the separation of taxa, which is usually based on morphological and micromorphological reproductive features. pollen grains of 10 taxa representing three groups of taxa in iran, the n. caspica group, the n. persica group and the n. lutea ...

a research study was carried out on the indirect selection efforts amongst small scale holders of west african dwarf (wad) goats based on coat pigmentation and wattle types in ogbomoso, nigeria using personal interviews and structured questionnaires given using simple random on-farm techniques. the questionnaires were focused on the ownership distribution, preferred pigmentation and wattle type...

Skin pigmentation is a major feature of skin, and marker associated with beauty, health aging. Among the past genome-wide association studies on skin pigmentation, relatively small proportion have focused Chinese population. Large-scaled based measured phenotypes are particularly rare in other East Asian populations. In Jidong cohort study (N = 3,544), we low-exposed area colorimeter performed ...

Hyla versicolor, a tetraploid treefrog, is reported to have originated via multiple hybridization events involving three diploid ancestors. Its complex reticulate history provides insights into the roles that polyploidy and hybridization can play in the origin of species.

Recent studies demonstrated pigmented cells both in the murine heart, in pulmonary veins, and in brain arteries. Moreover, a role for melanocytes in the downregulation of inflammatory processes was suggested. As there is increasing evidence that inflammation is contributing significantly to the pathogenesis of intracranial aneurysms, melanocyte-like cells may be relevant in preventing age-relat...
