2. 1. Anabolic Androgenic Steroids : Neurobiological Effects of Nandrolone, Testosterone, Trenbolone, and Stanozolol

   Author : Sofia Zelleroth; Mathias Hallberg; Astrid Bjørnebekk; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anabolic androgenic steroids; testosterone; nandrolone; trenbolone; stanozolol; central nervous system; primary cortical cell cultures; rats; multivariate concentric square field; novel object recognition.; Farmaceutisk vetenskap; Pharmaceutical Science;

   Abstract : The use of anabolic androgenic steroids (AAS) for recreational purposes is a health concern, as long-term AAS-use in supraphysiological doses is associated with severe physical and psychological adverse effects. Several behavioral and cognitive problems are reported after long-term AAS-use, and alterations in brain morphology as well as neurotransmitter systems have been reported. READ MORE

4. 2. Growth Hormone and Anabolic Androgenic Steroids : Effects on Neurochemistry and Cognition

   Author : Alfhild Grönbladh; Mathias Hallberg; Jörgen Isgaard; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Growth hormone; anabolic androgenic steroids; nandrolone decanoate; insulin-like growth factor; GABAB; opioids; memory; water maze; autoradiography; central nervous system; rats; Biological Research on Drug Dependence; Biologisk beroendeforskning;

   Abstract : Growth hormone (GH) stimulates growth and metabolism but also displays profound effects on the central nervous system (CNS). GH affects neurogenesis and neuroprotection, and has been shown to counteract drug-induced apoptosis in the brain. READ MORE

5. 3. Progestagenic Aquatic Contaminants Act as Potent Androgens in Fish : Experimental Studies in Three-spined Stickleback and Zebrafish

   Author : Johan Svensson; Björn Brunström; Ingvar Brandt; Ian Mayer; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pharmaceuticals as contaminants; Progestins; Androgenic properties; Fish; Biologi med inriktning mot ekotoxikologi; Biology with specialization in Environmental Toxicology;

   Abstract : The extensive use of pharmaceuticals and their poor removal by wastewater treatment plants has led to the emergence of pharmaceutical compounds as global aquatic contaminants. Progestins, the synthetic analogues to progesterone (P4), are receiving increasing attention as contaminants and have been shown to impair reproduction in fish and amphibians at low ng L-1 concentrations.

7. 5. Hormone therapy and the breast : aspects on proliferation, apoptosis and mammographic density

   Author : Peter Conner; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Breast cell proliferation; fine needle aspiration cytology; menopause; hormone replacement therapy; tibolone; mammographic breast density; continuous combined hormone therapy; p53; apoptosis; cynomolgus macaques.;

   Abstract : Breast cancer is the major malignancy among women in the western world. The breast is clearly a target organ for sex steroid hormones and hormonal treatments have been associated with an increased risk of breast cancer. Still, basic knowledge as to how sex steroids influence the normal breast is remarkably poor. READ MORE
