1. 21. The evolution of sexual dimorphism and its genetic underpinnings

   Författare :Philipp Kaufmann; Elina Immonen; Tim Connallon; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sexual conflict; sex-specific dominance; maintenance of genetic variance; sexual antagonism; sex chromosomes; Y haplotypes; artificial selection; sexual dimorphism; Callosobruchus maculatus; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

   Sammanfattning : Sexual dimorphism often constitutes the largest phenotypic variance within species but it is puzzling how sexual dimorphisms evolve because most of the genome is shared between the sexes. Sexually antagonistic (SA) selection on a shared genome sets the stage for intralocus sexual conflict. LÄS MER

3. 22. Political conflicts - Dissent and antagonism among political parties in local government

   Författare :Louise Skoog; Göteborgs universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; democracy; political conflict; party conflict; political dissent; antagonistic behaviour; multi-methods; local government; local politics; political parties; causes of conflict; effects of conflicts;

   Sammanfattning : Political conflicts arise out of, or are at least nourished by, divisions and tensions in society over how resources are distributed between citizens and social groups. In the parliamentary arena, these conflicts are manifested by political parties representing the interests of their voters. LÄS MER

5. 24. OXYTOCIN AND VASOPRESSIN IN UTERINE ACTIVITY. Receptor-mediated agonism and antagonism with special regard to the aetiology and treatment of preterm labour and primary dysmenorrhoea

   Författare :Thomas Bossmar; Lund Obstetrik och gynekologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics; primary dysmenorrhoea.; preterm labour; vasopressin antagonist; receptors; oxytocin antagonist; vasopressin; Oxytocin; gynaecology; andrology; reproduction; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet;

   Sammanfattning : With a view to the aetiology and treatment of preterm labour and primary dysmenorrhoea we studied the influence of sexual steroids on the plasma levels of oxytocin and vasopressin, effect of these peptides on uterine contractility in vitro and in vivo, receptor concentrations and antagonists to oxytocin and vasopressin. In postmenopausal women oestrogen increased the concentrations in plasma of both peptides, whereas progesterone increased oxytocin but decreased vasopressin levels. LÄS MER

7. 25. The endothelin system and cardiopulmonary dysfunction in porcine endotoxin shock

   Författare :Michael Wanecek; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Endothelin; endothelin receptor antagonism; cyclooxygenase inhibition; endotoxin; sepsis; shock; pulmonary hypertension; cardiac dysfunction;

   Sammanfattning : The endothelium-derived peptide endothelin-1, acting via the endothelinA and endothelinB receptors, possesses strong vasoconstrictive properties shown to affect pulmonary and systemic circulation as well as cardiac function. During septic and endotoxin shock a marked increase in circulating plasma endothelin-1 levels is observed which is associated with morbidity, cardiac dysfunction and lung injury. LÄS MER
