1. Ovarian steroids in rat and human brain : effects of different endocrine states
Sammanfattning : Ovarian steroid hormones are known to produce several different effects in the brain. In addition to their role in gonadotropin release, ovulation and sexual behaviour they also seem to affect mood and emotions, as shown in women with the premenstrual tension syndrome. Some steroids have the ability to affect brain excitability. LÄS MER
2. Effects of Mobile Phone Radiation upon the Mammalian Brain
Sammanfattning : oday about half of the world's population owns the microwave producing mobile phones. The blood-brain barrier (BBB) protects the mammalian brain from potentially harmful substances circulating in the blood. LÄS MER
3. Stereoselective Transport of Drugs Across the Blood-Brain Barrier (BBB) In Vivo and In Vitro : Pharmacokinetic and Pharmacodynamic Studies of the (S)- and (R)-Enantiomers of Different 5-HT1A Receptor Agonists and Antagonists
Sammanfattning : Delivery of drugs to the brain requires passage across the blood-brain barrier (BBB). Both for drugs already on the market and for new drugs under development, it is important to know to what extent a drug enters the CNS. Many drugs used clinically are racemic mixtures, i.e. LÄS MER
4. Brain Regeneration - in vitro and in vivo studies of exercise-related effects on brain plasticity
Sammanfattning : Neural stem and progenitor cells in the germinal regions of the adult brain, such as the hippocampus, are of great interest, because they provide the possibility for enhanced brain plasticity or can contribute to endogenous cell replacement after injury or disease. Voluntary exercise was recently shown to robustly induce cellular and structural plasticity, thereby contributing to overall brain health. LÄS MER
5. Signal transduction in the brain : modulation of receptor-mediated inositol phospholipid breakdown by potassium and fluoride ions
Sammanfattning : Neurotransmitter receptor types mediating the generation of intracellular signals are of two types; ligand-gated ion channels and G protein coupled receptors. The effector enzyme phosphoinositide-specific phospholipase C (PLC) is modulated by stimulation of G protein coupled receptors, leading to an increased breakdown of inositol phospholipids ("Ptdlns breakdown").
