  2. 1. Nitric oxide in central nervous structures associated with water balance and micturition

    Author : Anders Nylén; Lunds universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacological sciences; spinal projections; True Blue; cystometry; circumventricular organs; paraventricular nucleus; supraoptic nucleus; NADPH diaphorase; immunohistochemistry; oxytocin; 8-arginine-vasopressin; hypothalamus; rat; micturition; nitric oxide; water balance; neuronal nitric oxide synthase; pharmacognosy; pharmacy; toxicology; Farmakologi; farmakognosi; farmaci; toxikologi;

    Abstract : The role of nitric oxide (NO) in the central control of water balance and micturition has not yet been established. In the present thesis, where female rats were used, neuronal NO synthase (nNOS) distribution was studied in structures of the central nervous system known to be associated with the above mentioned control.

  4. 2. Peptidergic projections from the rat paraventricular hypothalamic nucleus to the spinal cord

    Author : Martin Hallbeck; Arthur Loewy; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The survival of the organism is dependent on keeping a balanced internal milieu in an ever-changing environment The process to achieve this balance is called homeostasis and it is accomplished by the consonant action of the endocrine system and the autonomic nervous system. Specific parts of the central nervous system (CNS) control these systems in response to various sensory inputs. READ MORE

  5. 3. Modulation of the HPA axis alters the sensitivity of the cochlea to acoustic trauma

    Author : Yeasmin Tahera; Karolinska Institutet; Karolinska Institutet; []
    Keywords : HPA axis; corticosterone; glucocorticoid receptor; NFêB; spiral ganglion neurons; cochlea; acoustic trauma; paraventricular nucleus;

    Abstract : The hypothalamic pituitary adrenal axis (HPA axis) regulates nearly all neuroendocrine responses of the body. An active HPA axis is crucial to maintaining homeostasis. An altered reactivity of the HPA axis can affect several physiological systems including the auditory system. READ MORE

  6. 4. Neuropeptide circuitries regulating food and water intake

    Author : Christian Broberger; Karolinska Institutet; Karolinska Institutet; []
    Keywords : agouti gene-related protein; anorexia mutation; arcuate nucleus; cholecystokinin; cocaine- and amphetamine-regulated transcript; coexistence; confocal microscopy; dorsal root ganglion; feeding; hypocretin; immunohistochemistry; in situ hybridization; melanin-concentrating hormone; nodose ganglion; nucleus tractus solitaxii; orexin; paraventricular nucleus; satiety; sensory neurones; pro-opiomelanocortin; vagus nerve;

    Abstract : An adequate supply of nutrients through food intake is critical for survival, as evidenced by disorders such as obesity and anorexia, which in the long run may be life-threatening. Feeding behaviour is ultimately controlled by interacting neuronal populations in the brain. READ MORE

  7. 5. Leptin targets in the brain regulating body weight : receptors and down-stream mediators of leptin in neurons of the hypothalamus and brainstem

    Author : Marie-Louise Håkansson Ovesjö; Karolinska Institutet; Karolinska Institutet; []

    Abstract : Obesity is a disease which has become a global epidemic that is beginning to replace undernutrition and infectious diseases as the most significant contributor to ill health in the world. In particular, obesity is associated with diabetes mellitus, hypertension and coronary heart disease. READ MORE
