1. 6. Reciprocal interactions of neuropeptide y and angiotensin II receptors with a2-adrenoceptors in the nucleus tractus solitarii of the rat

   Sammanfattning : Neuropeptide Y (NPY), angiotensin II (Ang II) and adrenergic transmission lines in the nucleus tractus solitarii (NTS), the major relay nucleus involved in the cardiovascular reflex, play an important role in central cardiovascular control. The present work explored reciprocal interactions of NPY and Ang II receptor subtypes with a2-adrenoceptors in the NTS of the normotensive Sprague-Dawley rat (SD), the normotensive Wistar Kyoto rat (WKY) and the spontaneously hypertensive rat (SHR) by using a cardiovascular analysis, quantitative receptor autoradiography, immunocytochemistry and in situ hybridization techniques.

3. 7. Adrenoceptors and nerve growth factor. Effects of electro-acupuncture and physical exercise in rats with steroid-induced polycystic ovaries

   Författare :Luigi Manni; Göteborgs universitet; []
   Nyckelord :;

   Sammanfattning : Polycystic ovary syndrome (PCOS) is complex endocrine and metabolic disorder associated with ovulatory dysfunction, follicular cyst and hyperandrogenism. The abnormalities detected in PCOS have been attributed to primary defects in the hypothalamic-pituitary unit, the ovarian microenvironment, the adrenal gland, and the insulin/insulin-like growth factor (IGF)-1 metabolic regulatory system.

4. 8. Characterization of ß3-adrenoceptor function in human fat cells

   Författare :Johan Hoffstedt; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :adipocyte; ß3-adrenoceptors; FFA; lipolysis; noradrenaline; polymorphism;

   Sammanfattning : Human white adipocytes have, besides ß1- and ß2-adrenoceptors, also been found to express a third ß-adrenergic receptor, termed the ß3-adrenoceptor. The functional role and clinical implications of the ß3-adrenoceptor is however poorly elucidated. LÄS MER

5. 9. Polycystic ovary syndrome : a study of adipocyte lipolysis in relation to endocrine and metabolic status

   Författare :Ingvar Ek; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Adipocyte; beta-adrenoceptors; FFA; hyperandrogenism; HSL; insulin resistance; lipolysis; PCOS; PKA;

   Sammanfattning : The aim of the present thesis was to obtain insight into possible regulatory effects of androgens on the regulation of lipolysis in subcutaneous as well as visceral adipose tissue in women with the polycystic ovary syndrome (PCOS). In non-obese women with PCOS, adrenergic lipolysis was investigated in both subcutaneous abdominal and visceral adipose tissue and several, novel disturbances were found. LÄS MER

7. 10. Studies on production and function of pulmonary nitric oxide

   Författare :Christofer Adding; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :adrenaline; adrenoceptors; beta-adrenoceptors; calcium; carbon dioxide; catecholamines; chemiluminescence; exhaled; gadolinium chloride; high frequency oscillatory ventilation; nitric oxide; pulmonary; pulmonary circulation; stretch; sympathoadrenal; veratrine;

   Sammanfattning : Nitric oxide is involved in pulmonary vascular and bronchial regulation and appears to be of paramount importance in the adaptation of the pulmonary circulation at birth. Nitric oxide is present in exhaled gas. LÄS MER
