A team of University of California, Irvine researchers have published the first comprehensive overview of the major changes that occur in mammalian skin cells as they prepare to heal wounds. Results from the study provide a blueprint for future investigation into pathological conditions associated with poor wound healing, such as in diabetic patients.
Advances in treatment have led to the largest yearly declines in deaths due to melanoma ever recorded for this skin cancer, results of a new study suggest.
Russian researchers showed the possibility of blending two incompatible components -- a protein and a polymer -- in one electrospun fiber. The study also demonstrates that the resulting mat can gradually release the protein. Blended mats containing proteins are promising for biomedical applications as burn and wound dressings, matrices for drug delivery and release, and in tissue engineering.
Acne treatment including the highly effective acne medication isotretinoin should be made more readily available despite reports of its association with depression and teen suicide, a study recommends.
Scientists have identified the mechanism that allows skin cells to sense changes in their environment, and very quickly respond to reinforce the skin's outermost layer. The findings provide insight into how errors in this process might lead to skin conditions like psoriasis.
Scientists show light-activated molecular drills effectively kill cells in whole eukaryotic organisms. The drills developed at Rice University, designed to target drug-resistant bacteria, cancer and other disease-causing cells, can now be used to kill whole organisms and drill into skin for therapeutic treatment.
Psychological stress has been proposed as a risk factor for melanoma, but clinical evidence is limited. A recent British Journal of Dermatology study funded by the European Academy of Dermatology and Venereology looked for a potential link between the death of a partner, which is one of the most stressful life events, and melanoma.
Netherton syndrome is exacerbated by the presence of Staphylococcus aureus and Staphylococcus epidermidis living on human skin report University of California San Diego School of Medicine researchers.
Our skin protects us from physical injury, radiation and microbes, and at the same time produces hair and facilitates perspiration. Details of how skin cells manage such disparate tasks have so far remained elusive. Now, researchers at Karolinska Institutet in Sweden have systematically mapped skin cells and their genetic programs, creating a detailed molecular atlas of the skin in its complexity. The study is published today in the scientific journal Cell Stem Cell.
Studying eczema, researchers at Washington University School of Medicine in St. Louis have found that boosting the number of natural killer cells in the blood is a possible treatment strategy for the skin condition and also may help with related health problems, such as asthma.
