Resistance of melanized yeast cells of Paracoccidioides brasiliensis to antimicrobial oxidants and inhibition of phagocytosis using carbohydrates and monoclonal antibody to CD18
(Instituto Oswaldo Cruz, Ministério da Saúde, 2009-07-01)
Paracoccidioides brasiliensis, a thermal dimorphic fungal pathogen, produces a melanin-like pigment in vitro and in vivo. We investigated the involvement of carbohydrates and monoclonal antibody to CD18, on phagocytosis ...
Recurrent Evolution of Melanism in South American Felids
(Elsevier, 2015)
Morphological variation in natural populations is a genomic test bed for studying the interface
between molecular evolution and population genetics, but some of the most interesting
questions involve non-model organisms ...
Exploring the genetic basis of melanic coloration in Diglossa flowerpiercers (Thraupidae)
(UniandesBiologíaFacultad de CienciasDepartamento de Ciencias Biológicas, 2020)
Comprender la base genética de la coloración ha sido de interés central en la biología evolutiva de los vertebrados. En el caso de las aves, el receptor de melanocortina-1 (MC1R) ha tenido un papel protagónico como uno de ...

Catecholamine-β-alanyl ligase in the medfly Ceratitis capitata
(Pergamon-Elsevier Science Ltd, 2002-06)
Dopamine (DA) and norepinephrine (NE) derivatives play an important role in the sclerotization and pigmentation of insect cuticles by serving as precursors for cuticular cross-linking. Protein preparations from prepupae ...
Morphological adaptation to coastal marshes in spite of limited genetic structure in the Neotropical passerine Spartonoica maluroides (Aves: Furnariidae)
(Wiley Blackwell Publishing, Inc, 2013-04)
Tidal marshes present profound adaptive challenges to terrestrial vertebrates. For example, North American sparrows have relatively longer and thinner bills and darker dorsal plumage in coastal saltmarshes than in interior ...
Use of a Melanin-Type Polymer to Improve the Selectivity of Glucose Biosensors
(Taylor, 2003-01-02)
This paper reports the advantages of using a melanin-type polymer to improve the selectivity of glucose biosensors based on carbon paste electrodes containing Pt and glucose oxidase (GOx). The resulting bioelectrodes combine ...
Challenges in the Therapy of Chromoblastomycosis
(Springer, 2013-06-01)
Chromoblastomycosis (CBM) is an implantation mycosis mainly occurring in tropical and subtropical zones worldwide. If not diagnosed at early stages, patients with CBM require long-term therapy with systemic antifungals ...
