Introduction: Hyperpigmentation disorders (HPD) are a frequent reason for dermatology consultations as they can impair quality of life. The most HPD melasma, post-inflammatory hyperpigmentation and solar lentigos with increased melanin content on top other pathophysiologic features. development an efficient safe ingredient to manage facial skin tone heterogeneities is great importance. Objectiv...

HIGHLIGHTS • Molecular analysis of aurofusarin biosynthesis in F. culmorum. Mycelial pigmentation depending on gene expression and accumulation. Pigmentation variations growth phase.

Marine macroalgae have an interesting profile of bioactive compounds and gained tremendous attention in cosmeceuticals with negligible toxicity effects (cytotoxicity, reproductive toxicity, genotoxicity, mutagenicity, carcinogenicity, etc.) on humans exhibit strong benefits for the skin. Among diversified compounds, phenolic are group phytochemicals found high amounts great structural diversity...

Introduction Soles, as most of flatfishes, live in sandy bottoms in order to guarantee food availability and protection from predators (Kruuk, 1963). In commercial sole culture, the use of sand has been considered a serious obstacle to maintain hygienic conditions (Howell, 1997), but problems arise when they are kept on hard-bottomed tanks without sand. A higher occurrence of Black Patch Necros...

Birds show striking interspecific variation in their use of carotenoid-based coloration. Theory predicts that the use of carotenoids for coloration is closely associated with the availability of carotenoids in the diet but, although this prediction has been supported in single-species studies and those using small numbers of closely related species, there have been no broad-scale quantitative t...

INTRODUCTION Melanin pigmentation in the oral mucosa occurs as a result of several reasons one of which is smoking. Cigarette smoke induces numerous side effects in the people who do not smoke, but are in the same environment. The aim of this study was to evaluate the role of parental smoking on pigmentation of their children's oral mucosa. MATERIALS AND METHODS This study was carried out as ...

AIM Melanin pigmentation of the gingiva occurs in all ethnicities. Excessive pigmentation is an esthetic concern that has increased awareness about de pigmentation procedures. The purpose of the present study was to correlate skin color and gender with intensity and distribution of gingival melanin pigmentation in a group of South Indians. METHODS 200 male and female non smoking healthy subje...

A paralytic condition of farm stock in South West Africa, characterized by prominent neuronal and some mild extraneuronal pigmentation, is described. The distribution of the pigment, which was mainly located in the larger neurones of the brain and spinal cord, is given. Experimental evidence, obtained by feeding the plant, is presented that the condition is caused by Trachyandra laxa var. laxa....

Dermatological disorders related to pigmentation result in tenuous hyper or hypopigmentation Cosmetic and pharmaceutical products containing depigmenting substances are used in the treatment of patients who have high pigmentation disorders, such as melasma or chloasma, post-inflammatory hyperpigmentation, senile lentigo and ephelides. Skin lightening agents are not yet totally effective or safe...

Epidemiological studies have identified racial differences in susceptibility to numerous diseases, including several ocular and skin diseases characterized by increased vascular growth. In most cases, the specific mechanisms and genetic variants responsible for these differences have remained elusive. In this issue of the JCI, Adini et al. explore a direct connection between skin pigmentation a...
