Skin Cancer and Uv Protection

The incidence of skin cancer is increasing by epidemic proportions. Basal cell cancer remains the most common skin neoplasm, and simple excision is generally curative. On the other hand, aggressive local growth and metastasis are common features of malignant melanoma, which accounts for 75 percent of all deaths associated with skin cancer. The primary cause of skin cancer is long exposure to so...

Radical Skin/Sun Protection Factor RSF – Protection against UV-induced Free Radicals in Skin

N atural ageing of the skin is enhanced by environmental factors. Solar UV exposure is one of the main exogenous factors that is participating in that process and that can lead to photoageing, immunosuppression, and photocarcinogenesis. Using a new RSF method to determine UVinduced free radical injuries in the skin, it is possible to quantify the protective effect of sunscreens and UV-filters. ...

Skin Barrier Protection

The largest organ of the human body is the skin with its ∼2 m 2 surface area that envelopes the whole organism defining its physical border and which most importantly provides a barrier against internal organ dehydration and external penetration of noxious substances. The critical importance of the skin barrier is appreciated when it is lost such as in skin burns or compromised such as in atopi...

Ghrelin and Stress Protection

D cells Endocrine cells belonging to the amine precursor uptake and decarboxylation (APUD) system known to release the hormone, somatostatin. Endocrine cells (EC) Release the hormone motilin and the neurotransmitter serotonin. Enterochromatoffin-like cells (ECL) Known to release histamine, a potent stimulant of gastric acid secretion in the stomach. They are the predominant endocrine cell-type ...
