    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Androgenic anabolics; male adolescents; appearance; intervention; attitudes; self-confidence; body image; gym; peer pressure; focus-groups;

    Sammanfattning : Background: Misuse of androgenic anabolic steroids in US is well known. Less is known about the situation in Sweden and Europe. If there does exist a problem of misuse, it is important to investigate prevalence, risk-factors and attitudes towards anabolics. This knowledge is vital in order to design intervention. LÄS MER

    Sammanfattning : Stem cells have the capacity for both self renewal, and to form all cell types in the body. Interestingly, so called neural stem cells (NSCs) are found in the adult human brain, which is of significance both out of a developmental perspective and from a clinical point of view. LÄS MER
