Natural light and UV radiation (UVR) from artificial sources has always been recognized for and endowed with health-giving powers as well as for its tonic value of generating a feeling that it is good for our psyche and contributes to the synthesis of vitamin D essential for maintaining ...
The explanation about the function of melanin in the substantia nigra at mesencephalon has been elicited diverse theories, being considered its presence in midbrain only as a by-product of dopamine metabolism. Our discovery of the intrinsic property of melanin to split and re-form the water ...
In addition, the cell wall of living or heat-killed melanized, but never unmelanized, appressoria collapsed during plasmolysis due to cytorrhysis. Melanin, having a differential permeability to water and solute, allowed sealed appressoria to establish and maintain a high internal solute ...
Retinal response to the acute hypoxia and reoxygenation were shown to be independent of melanin presence in the eye pigmental epithelium (PE), i.e. in the retinas of both pigmented animals and albinos hypoxia survived an increase in the content of hydroperoxidases and malonyl dialdehyde; subsequ...
A possible mechanism by which pigment production might cause induction of the ToxR regulon due to generation of hydrogen peroxide was supported by results from tests showing that externally supplied H(2)O(2) led to higher TcpA levels. Taken together, our findings suggest that melanin pigment ...
We previously developed a quantitative autoradiographic technique with special forceps for measuring unscheduled DNA synthesis (UDS) in mouse skin after treatment with ultraviolet light in vivo. By this method, we investigated the relationship between the protective role of melanin and UV-induced DNA re...

Melanin concentrating hormone (MCH) and neuropeptide EI (NEI) are two peptides produced from the same precursor in mammals, by cleavage at the Arg145-Arg146 site and the Lys129-Arg130 site, respectively. We performed co-localization studies to reveal simultaneously the expression of MCH mRNA an...
