[Metabolism of nitric oxide (NO) and arginine: significance for male health]. / Stickstoffmonooxid(NO)- und Arginin-Stoffwechsel und deren Bedeutung in der Männergesundheit.

Since the first description of the "endothelium-derived relaxing factor" (EDRF) in 1980 the function of the endothelium has developed into a field of research of its own. The most important endothelial factor is nitric oxide (NO), which is formed from l-arginine with the help of NO synthase (NOS). Disturbances of the endothelial function play an important role in men's health such as atherogenesis and erectile dysfunction and are also followed by morphological vessel changes. Furthermore, NO seems to play an important role in LUTS (lower urinary tract symptoms) and male fertility.

[Nutrition, lifestyle, physical activity, and supportive care during chemotherapeutic treatment]. / Ernährung, Lebensweise, Aktivitäten und supportive Massnahmen unter chemotherapeutischer Behandlung.

With improvements in cancer survival rates, more patients with cancer are living longer and the influence of nutrition, lifestyle, physical activity as well as supportive care during and after chemotherapy is of increasing interest. In several malignancies smoking cessation increases cancer survival. Similar effects are expected by healthy nutrition. Regular physical activity of cancer patients reduces drug interactions of chemotherapy, decreases the number of comorbid conditions, and helps patients maintain independence as long as possible. For supportive care during chemotherapy the 5-HT3 receptor antagonists are more effective for the prevention of chemotherapy-induced nausea and vomiting. There are several colony-stimulating factors (e.g. GCSF, erythropoietin) for hematopoietic recovery post-chemotherapy. Altogether supportive care of chemotherapy reduces toxicity and increases efficacy.
