The CD24hi smooth muscle subpopulation is the predominant fraction in uterine fibroids.

Uterine fibroids are the most common gynecological tumors affecting women in their reproductive age. Despite this high incidence the pathogenesis of fibroids is widely unsolved. Whereas formerly only imbalances in hormonal levels were considered to account for tumor development, the identification of genetic changes likely to affect myometrial stem cell reservoirs provided a novel approach to fibroid genesis.

Induction of overt menstruation in intact mice.

The complex tissue remodeling process of menstruation is experienced by humans and some primates, whereas most placental mammals, including mice, go through an estrous cycle. How menstruation and the underlying mechanisms evolved is still unknown. Here we demonstrate that the process of menstruation is not just species-specific but also depends on factors which can be induced experimentally.

Proteasome inhibition: a new anti-inflammatory strategy.

The ubiquitin-proteasome pathway has a central role in the selective degradation of intracellular proteins. Among the key proteins modulated by the proteasome are those involved in the control of inflammatory processes, cell cycle regulation, and gene expression. Consequently proteasome inhibition is a potential treatment option for cancer and inflammatory conditions.

Decorative cosmetics improve the quality of life in patients with disfiguring skin diseases.

Dermatoses may have a significant impact on a patient's quality of life, namely the relationship to others, self-image and self-esteem. We therefore asked whether the application of decorative cosmetics might increase their quality of life. Twenty female patients (16-69 y) with skin diseases affecting the patients' face (acne, n = 8; rosacea, n = 9; chronic discoid lupus erythematodes, n = 2; vitiligo, n = 1) were investigated.
