Heat stress: A risk factor for skin carcinogenesis

Licking as a factor affecting dosage in skin carcinogenesis.

The dose of carcinogen applied to the skin is one of the most important factors determining the ultimate tumor incidence (9, 10). However, the experiment of Calcutt and Powell (3) demonstrated that the effective dose of the carcinogen may be considerably lower than that measured onto the skin. Using fluorimetric methods and a single application of 3 mg. of benzpyrene (0.05 ml. of a 6 per cent s...

Metabolic Syndrome as a Risk Factor for Osteoarthritis

  Metabolic syndrome refers to a set of conditions that include high blood pressure, increased insulin level in the blood, the accumulation of the excess fat around the abdomen, and increased blood lipids. In metabolic syndrome, the vast majority of these conditions are simultaneously present, and the risk of developing heart disease, stroke, and diabetes rises. Besides, osteoarthritis or degen...

Indoor Tanning: A Bio-Behavioral Risk Factor for Skin Cancer

A critical role for ras-mediated, epidermal growth factor receptor-dependent angiogenesis in mouse skin carcinogenesis.

Epidermal growth factor receptor (EGFR) plays a critical role in epidermal biology. Abnormal EGFR function has been described in epithelial tumors including those induced by two-stage chemical carcinogenesis in mouse skin. A large body of evidence indicates that in this model, activation of Ha-ras is the critical event in papilloma formation, a process that involves epidermal proliferation and ...
