1. 6. Early Environment and Adolescent Ethanol Consumption : Effects on Endogenous Opioids and Behaviour in Rats

   Författare :Loudin Daoura; Ingrid Nylander; Erika Roman; Bo Söderpalm; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alcohol; intermittent ethanol access; maternal separation; multivariate concentric square field™ test; maternal behavior; ultrasonic vocalization; adolescent; neonatal handling; Farmaceutisk farmakologi; Pharmaceutical Pharmacology;

   Sammanfattning : Excessive and compulsive ethanol drinking is one of the most serious public health issues. Therefore, it is vital to increase the knowledge about risks and protection for alcohol use disorders (AUD) to optimize prevention and treatment strategies. LÄS MER

3. 7. Maternal separation in the rat : long-term effects of early life events on emotionality, drug response and neurobiology

   Författare :Maarit Marmendal; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Early deprivation; Alcohol intake; Anxiety; Corticosterone; Maternal separation; HPA axis; Maternal care; Monoamines;

   Sammanfattning : Exposure to early stress and emotional trauma in humans are associated with an increased risk to develop psychiatric disorders, for example, anxiety, depression and drug abuse. Furthermore, disruptions in stress hormone and neurotransmitter levels as well as structural changes in the brain have been connected to early adversities. LÄS MER

4. 8. Evolutionary implications of acidification: a frog’s eye view

   Författare :Katja Räsänen; Andrew Hendry; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; acid stress; amphibians; local adaptation; maternal effects; maternal investment; Biologi; Biology; Biologi; populationsbiologi; Population Biology;

   Sammanfattning : Understanding the diversity of life is one of the main aims of evolutionary biology, and requires knowledge of the occurrence and causes of adaptive genetic differentiation among geographically distinct populations. Environmental stress caused by acidity may cause strong directional selection in natural populations, but is little explored from an evolutionary perspective. LÄS MER

5. 9. Polybrominated dibenzo-p-dioxins : Natural formation mechanisms and biota retention, maternal transfer, and effects

   Författare :Kristina Arnoldsson; Peter Haglund; Patrik Andersson; Walter Vetter; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polybrominated dibenzo-p-dioxins; PBDDs; Baltic Sea; uptake; retention; maternal transfer; metabolism; bioavailability; natural formation; precursor; bromoperoxidase; bromophenol; photochemical transformation; oxidative coupling; hydroxylated polybrominated diphenyl ethers; Chemistry; Kemi; analytisk kemi; Analytical Chemistry;

   Sammanfattning : Polybrominated dibenzo-p-dioxins (PBDD) and dibenzofurans (PBDF) are a group of compounds of emerging interest as potential environmental stressors. Their structures as well as toxic responses are similar to the highly characterized toxicants polychlorinated dibenzo-p-dioxins. LÄS MER
