  2. 1. Respiratory activity in medulla oblongata and its modulation by adenosine and opioids

    Author : Eric Herlenius; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Adenosine; opioids; brainstem; perinatal rat; respiration; medulla oblongata;

    Abstract : From the moment of birth the complex neuronal networks generating breathing has to function continuously and adapt to the new postnatal environmental demands. This thesis aims at studying the perinatal development of respiratory control and its modulation by adenosine and opioids. READ MORE

    Abstract : Recent research demonstrated that besides a role in sex determination and male fertility, the Y chromosome is involved in additional functions including prostate cancer, sex-specific effects on the brain and behaviour, graft-versus-host disease, nociception, aggression and autoimmune diseases. The results presented in this thesis include an analysis of sex-biased genes encoded on the X and Y chromosomes of rodents. READ MORE

  5. 3. Cholinergic receptors in human prenetal brain : presence, distribution and influence of nicotine and ethanol

    Author : Lena Falk; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Events early in life, including exposure to various compounds, may cause disturbances in brain development. Both maternal smoking and alcohol drinking during pregnancy can induce preand postnatal death, cognitive and neurobehavioral disturbances. READ MORE

  6. 4. Ovarian steroids in rat and human brain : effects of different endocrine states

    Author : Marie Bixo; Bengt Winblad; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Progesterone; 5a-pregnane-3.20-dione; estradiol; testosterone; rat brain; human brain; PMSG-model; steroid anaesthesia;

    Abstract : 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. READ MORE

  7. 5. Expression of cathelicidin antimicrobial peptides in man and rat

    Author : Stefan Termén; Karolinska Institutet; Karolinska Institutet; []
    Keywords : LL-37; rCRAMP; butyrate; colonic epithelium; central nervous system; transcription;

    Abstract : Endogenous antimicrobial peptides are effectors of innate immunity. They kill microorganisms by disrupting their cell membranes, but are also believed to have signaling functions in the immune system. They are present in epithelia, secretions and phagocytic cells. READ MORE
