Relationship Between Foveal Cone Specialization and Pit Morphology in Albinism [PDF]

, 2014
Purpose.Albinism is associated with disrupted foveal development, though intersubject variability is becoming appreciated. We sought to quantify this variability, and examine the relationship between foveal cone specialization and pit morphology in ...

SCD5 restored expression favors differentiation and epithelial-mesenchymal reversion in advanced melanoma [PDF]

, 2018
Our previous data supported a role for the Stearoyl-CoA desaturase (SCD5) in protection against malignancy, whereby it appears to functionally modify tumor stroma impairing tumor spread.

Neuroprotective effects of melanins and melanin derivatives from Calvatia Craniiformis and Xylaria plebeja against Parkinsonian toxins

Scientific Reports
Fungal melanins have remarkable bioactivities, but their practical applications are limited, partly due to their hydrophobic nature. Melanin modification with amino acids was reported to improve their water solubility. This research aimed to extract, and

Structural analysis and spectroscopic characterization of melanin-alginate films

Chemical Physics Impact
In this work, we present the spectroscopic and structural analysis of synthetic melanin incorporated within alginate films. We propose a synthesis methodology for alginate films with different concentrations of melanin.

Role of Melanin Chemiexcitation in Melanoma Progression and Drug Resistance

Frontiers in Oncology, 2020
Melanoma is the deadliest type of skin cancer. Human melanomas often show hyperactivity of nitric oxide synthase (NOS) and NADPH oxidase (NOX), which, respectively, generate nitric oxide (NO·) and superoxide (O2·−).

Magnetic Properties of Melanin Doped with Copper Oxide Nanoparticles

Engineering Proceedings
In this study, the analysis of XRD patterns reveals that both natural melanin and copper oxide-doped melanin exhibit amorphous structures. The absence of new peaks for Cu2O confirms that the copper oxide nanoparticles are effectively integrated into the ...

Microscale Thermophoresis as a Screening Tool to Predict Melanin Binding of Drugs

Pharmaceutics, 2020
Interactions between drugs and melanin pigment may have major impacts on pharmacokinetics. Therefore, melanin binding can modify the efficacy and toxicity of medications in ophthalmic and other disease of pigmented tissues, such as melanoma.
