Risks from firearms actually come from both ends of the barrel, according to a new study. Individuals at firing ranges are exposed to very high amounts of lead from shooting firearms, and exposure is as high at outdoor firing ranges as it is at indoor ranges.
The characteristics of human skin are heavily dependent on the hydration of the tissue -- in simple terms, the water content. This also changes its interaction with textiles. Up to now, it has only been possible to determine the interaction between human skin and textiles by means of clinical trials on human subjects. Now, researchers have developed an artificial gelatine-based skin model that simulates human skin almost perfectly.
Scientists have identified the gene responsible for generating acylceramide, the key lipid in forming the skin barrier that protects us from pathogens, allergens and other harmful substances. This finding could prove crucial in developing medicines for treating atopic dermatitis and ichthyosis.
Alopecia areata, atopic dermatitis and vitiligo are highly visible dermatologic conditions that can have a negative effect on patients’ quality of life and overall health. An emerging treatment option, however, could provide effective therapy.
