“We found that the microbiome in epidermis is unique. It is very different depending on age and gender. On the other hand, the microbiome in dermis is the same—regardless of age and gender. This has not been shown before,” said co-author Lene Bay, in a press release. Bay is a postdoctoral researcher at the department of immunology and microbiology at the University of Copenhagen.
Rates of skin cancer were 8.1% among homosexual men and 8.4% among bisexual men, statistically higher than the rate of 6.7% among heterosexual men. Skin cancer rates were 5.9% among homosexual women and 6.6% among heterosexual women, which was not a statistically significant difference. However, the rate of 4.7% among bisexual women was statistically significantly lower than heterosexual women.
“This study represents an important milestone for the field of plasma medicine,” said co-senior author Richard Wirz, PhD, professor of mechanical and aerospace engineering at UCLA Samueli. “It demonstrates that the microneedle patch can realize the plasma delivery while also working with the drug to improve the effectiveness of cancer therapy.”
“The novelty is that [the new lipid vesicles] enable the absorption of a drug of greater size than usual through the skin and opens a route of administration of other substances for therapeutic, diagnostic or even vaccination purposes through the intact skin, without having to be injected," said lead author Ana Melero, PhD.
