   Författare :Aleksandra Rybacka; Patrik Andersson; Christina Rudén; Anna Linusson; Uko Maran; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; QSAR; in silico; non-testing tools; risk assessment; exposure assessment; hazard assessment; carcinogenicity; mutagenicity; reproductive toxicity; endocrine disruption; estrogen; androgen; transthyretin; sorption; Environmental Science; miljövetenskap; Computer Science; datalogi; Toxicology; toxikologi; Statistics; statistik;

   Sammanfattning : According to the REACH regulation chemicals produced or imported to the European Union need to be assessed to manage the risk of potential hazard to human health and the environment. An increasing number of chemicals in commerce prompts the need for utilizing faster and cheaper alternative methods for this assessment, such as quantitative structure-activity or property relationships (QSARs or QSPRs).

3. 37. Testosterone, 17β-estradiol and pubertal growth

   Författare :Anna-Karin Albin; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; testosterone; estrogen; pubertal growth; growth hormone treatment;

   Sammanfattning : Background and aims: It is well established that the interaction of sex steroids with the growth hormone (GH)/ insulin-like growth factor 1 (IGF-1) axis is of major importance in children for normal pubertal growth. However, detailed understanding is still lacking. LÄS MER

4. 38. Hormone replacement therapy in rheumatoid arthritis

   Sammanfattning : It is known that some psychiatric disorders may deteriorate in relation to the menstrual cycle. However, in some conditions, such as premenstrual dysphoric disorder (PMDD), symptomatology is triggered mainly by the variations in ovarian steroid hormones. LÄS MER

7. 40. Effects of Endocrine Disrupting Chemicals on Human Endometrial Endothelial Cells In Vitro

   Författare :Malin Helmestam; Matts Olovsson; Anneli Stavreus-Evers; Yvonne Lundberg Giwercman; Uppsala universitet; []

   Sammanfattning : Evidence from an abundant number of studies suggests that human female reproductive functions have become impaired over the past half century and that there might be a relationship between endocrine disrupting chemicals (EDCs) and reduced fertility. It is, however, not known by what mechanisms EDCs affect different reproductive functions such as endometrial receptivity, embryo implantation and placentation. LÄS MER
