Clinical Patterns of Facial Pigmentation
2021Introduction: Pigmentary disorders of the skin are a great concern to the patient, more so when it involves the face. It is one of the common clinical presentations to the dermatology OPD. Facial pigmentation may be multifactorial and in some etiology may be known by a detailed history.

Pattern dystrophies of the retinal pigment epithelium
Clinical and Experimental Optometry, 2000We describe a family that shows autosomal dominant pattern dystrophy of the retinal pigment epithelium. There were 10 affected family members encompassing three generations. The various manifestations of these dystrophies, their inheritance characteristics, affects on vision function and their pathogenesis are discussed.

Patterned dystrophy of the retinal pigment epithelium
Ophthalmic Paediatrics and Genetics, 1986The authors describe a family presenting with a patterned dystrophy of the retinal pigment epithelium. The aspect of the macular area is granular to reticular with a tendency to a butterfly shape. Visual functions are normal or near-normal. A review of the literature is given.

CHLOROPLAST PIGMENT PATTERNS IN DINOFLAGELLATES1
Journal of Phycology, 1975SUMMARYThe chlorophylls and carotenoids of 22 species of dinoflagellates were analysed by thin layer chromatography, using 2‐dimensional sucrose plates, and 1‐dimensional polyethylene plates for chlorophylls c1and c2. Peridinin was the major carotenoid in 19 of the species, while fucoxanthin was the major carotenoid in 3.

On the Development of Pigment Patterns in Amphibians
American Zoologist, 1978synopsis. Pigmentary mutants in amphibians provide important vehicles for studying basic problems in development. Some of these mutants exert influences on the tissue environ? ment in which the chromatophores differentiate and others involve the expression of pigment in specific types of pigment cells.

Pigment Cell Pattern Formation
2017In this chapter, an LGCA is introduced as model for pattern formation in salamander larvae. After providing the biological background the model is defined and tested by means of simulations. Model results demonstrate that the larval stripe pattern can arise solely as a consequence of direct cell interactions.

Genetic and Developmental Aspects of Pathological Pigmentation Patterns
1985This review attempts to relate current ideas about pattern formation in normal development to the anatomical patterns formed by the lesions of certain poorly understood pigmentary disorders of the human skin. Although there is as yet little direct experimental evidence linking the two topics, the principles derived from laboratory experiments on ...

Pattern Formation by Coupled Oscillations: The Pigmentation Patterns on the Shells of Molluscs
1987The diversity and beauty of the pigmentation patterns on the shells of snails and bivalved molluscs invites us to construct models to understand their formation. The similarity of patterns in unrelated species on the one hand and the diversity in closely related species on the other encourage the assumption that most of them are generated by a common ...
