  1. 1. Neuropeptide Y - aspects of vasomotorresponses and receptor characterization

    University dissertation from Medicinska Institutionen Lunds Universitets sjukhus 22185 Lund

    Author : Torun Nilsson-Bergdahl; [2000]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; vasoconstriction; RT-PCR; receptor characterization; potentiation; NPY Y1 receptor; NPY; mitogenesis; hypertension; human arteries; forearm blood flow; cell culture; antisense oligodeoxynucleotides; BIBP3226; vasodilatation.; Physiology; Fysiologi; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi;

    Abstract : Abstract The aims of the present thesis were to examine neuropeptide Y (NPY) responses in different human and guinea pig vascular beds and in cultured human vascular smooth muscle cells (VSMC) and to characterize, with different NPY agonists and the specific NPY Y1 receptor antagonist (BIBP3226), the NPY receptors involved. NPY-induced strong and potent contractions in human cerebral and subcutaneous arteries and in guinea pig basilar arteries. READ MORE

  2. 2. Direct and endothelium-linked serotonergic control of vascular tone in human uterine and umbilical arteries

    University dissertation from Department of Pediatrics, Lund University

    Author : Caroline Karlsson; [1998]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; andrology; gynaecology; Obstetrics; vascular smooth muscle; uterine artery human ; umbilical artery human ; serotonergic receptor; 5-HT; noradrenaline; endothelium; NPY; reproduction; sexuality; Obstetrik; gynekologi; andrologi; reproduktion; sexualitet;

    Abstract : The serotonergic vascular control was investigated by in vitro pharmacology in the human uterine and umbilical arteries. The localisation of immunoreactive (IR) neuropeptide Y (NPY) and the influence of NPY on the adrenergic vascular effects in the human uterine artery were also studied. READ MORE

  3. 3. Innervation and Functional Aspects of Neuropeptides in the Coronary Circulation

    University dissertation from Department of Internal Medcine, University Hospital of Lund

    Author : Ole Saetrum Opgaard; [1996]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; immunohistochemistry.; mRNA; receptors; ET-B; ET-A; endothelin; substance P; calcitonin gene-related peptide; vasoactive intestinal peptide; acetylcholine; NPY; ATP; noradrenaline; nerves; sensory; parasympathetic; sympathetic; veins; Coronary; arteries; Endocrinology; secreting systems; diabetology; Endokrinologi; sekretion; diabetologi; Cardiovascular system; Kardiovaskulära systemet;

    Abstract : A network of perivascular nerve fibres was demonstrated in coronary arteries and veins from guinea-pig and man. Nerve fibres displaying immunoreactivity to neuropeptide Y (NPY) had a distribution pattern similar to those containing immunoreactivity to tyrosine hydroxylase. READ MORE

  4. 4. Winter Depression: Clinical, Psychosocial and Biochemical Characteristics

    University dissertation from Baba Pendse; [email protected]

    Author : Baba Pendse; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NPY.; Psychiatry; clinical psychology; psychosomatics; Psykiatri; klinisk psykologi; psykosomatik; CRH; Social characteristics; Psychopathology; Temperament; Nonseasonal major depression; Suicide attempt; Winter depression; SAD;

    Abstract : Seasonal Affective Disorder with depressive episodes during the autumn/winter seasons (winter depression) is common. Outpatients with winter depression were studied regarding temperament, psychopathology, social characteristics, psychosocial functioning and the neuropeptides corticotropin - releasing hormone (CRH) and neuropeptide Y (NPY), which are known to be involved in stress-regulation.

  5. 5. Studies of the Neuropeptide Y Receptor Y2 in Human and Zebrafish

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Helena Fällmar; Uppsala universitet.; [2011]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Y2-receptor; NPY; PYY; G-protein-coupled receptor; mutagenesis; receptor binding; zebrafish; evolution; MEDICINE Physiology and pharmacology Pharmacological research Pharmacology; MEDICIN Fysiologi och farmakologi Farmakologisk forskning Farmakologi; Farmakologi; Pharmacology;

    Abstract : The G-protein coupled receptors (GPCRs) comprise the largest family of receptors in humans and other vertebrates. They are embedded in the cell membrane and are activated by many different signaling molecules. Activation modulates cellular signal transduction pathways and influences many physiological processes.
