The term “Oro-facial pigmentation” refers to a wide range of lesions or conditions featuring a change of color of Oro-facial tissues. Pigmentation of the Orofacial tissues is seen in certain races or ethnic groups such as Indians, Africans and Europeans. Broadly classifying, Oro-facial pigmentation is divided into endogenous pigmentation and exogenous pigmentation. Endogenous pigmentation is du...
statement of problem: physiologic pigmentation of oral mucosa is considered as a prevalent entity among black people and those having relatively dark skin. gingival physiologic pigmentation may cause problems for some patients specially ladies as far as esthetics is concerned. to overcome the issue, the surgery might be suggested which can cause some problems due to its side effects. cryotherap...
This study evaluated the relation between rind colour and internal physicochemical sensory qualities of ‘Sanguinelli’ blood oranges, one main orange cultivars grown in Mediterranean region. To this end, 400 fruits were harvested three different orchards classified according to pigmentation intensity (slight, medium, intense, very intense). All individually by determining pulp colour, total solu...
The injection of an antagonistic anti-murine c-kit monoclonal antibody ACK2 during mouse embryonic development produced three distinctive pigmentation patterns on the coat of the offspring. Pattern 1 consisted of pigmentation in craniofacial and caudal regions and was induced by an ACK2 injection between 9.5 and 11.5 days post coitum (dpc). In pattern 2, the entire coat was unpigmented and was ...
To understand the mechanisms of morphological evolution and species divergence, it is essential to elucidate the genetic basis of variation in natural populations. Sexually dimorphic characters, which evolve rapidly both within and among species, present attractive models for addressing these questions. In this report, we map quantitative trait loci (QTL) responsible for variation in sexually d...
HIGHLIGHTS • Molecular analysis of aurofusarin biosynthesis in F. culmorum. Mycelial pigmentation depending on gene expression and accumulation. Pigmentation variations growth phase.
Phenotypic variability is the engine that drives future diversification with the expectation that polymorphic ancestors give rise to descendants harboring a subset of the ancestral variation. Here we examine evolutionary transitions from polymorphism to monomorphism in a visually striking New World radiation of fruit flies, the Drosophila cardini group. This group is distributed across the Amer...
BACKGROUND The negative pigment network (NPN) is seen as a negative of the pigmented network and it is purported to be a melanoma-specific structure. OBJECTIVES We sought to assess the frequency, sensitivity, specificity, and odds ratios (ORs) of NPN between melanoma cases and a group of control lesions. METHODS Digitalized images of skin lesions from 679 patients with histopathological dia...
