Three naturally occurring pyrrole acids were found in Sepia, human black hair, and bovine
choroid and iris melanosomes using high‐performance liquid chromatography and mass …

Uveal melanosomes from the iridal stroma contain both eumelanin and pheomelanin, the
ratio of which varies with iris color. Herein, we report the absorption coefficient at λ= 244 nm …

Disorders of cutaneous discoloration comprise a large group of skin conditions
characterized by an increase of chromophores of melanotic origin (hyperpigmentation) …

We developed a mathematical process to quantify the apparent darkness of solutions
containing melanin-like materials. The visible portion of their UV-Vis spectra is model using …

Melanin pigments are heterogeneous biopolymers and are widely distributed in nature.
They are produced by animals, plants, and microorganisms, such as pathogenic fungi and …

An evolutionary approach to the topic of melanins prompts some interesting considerations,
for it is clear that, if we adopt an inclusive definition of melanins (ie, pigments derived from …

A rapid, simple and highly sensitive flow-injection (FI) electrogenerated chemiluminescence
(ECL) method was developed for the determination of melanin, a biological pigment present …

Resumo O Mestrado Integrado em Ciências Farmacêuticas contém como última fase o
estágio curricular, nas áreas de farmácia comunitária e farmácia hospitalar. De facto, os …

The interplay between donor-specific anti-HLA antibodies (HLA-DSA), histology of active
antibody-mediated rejection (aABMRh), transplant glomerulopathy (cg), and graft failure in …

We have studied the formation of melanin-like pigments from catechol or pyrogallol and a
wide range of other phenolic compounds using Fe2+ and H2O2. Combining UV_Vis …
