Plasma noradrenaline and the pressor action of exogenous noradrenaline in normotensive subjects and patients with essential hypertension.

1978

1. An inverse relationship was found between plasma noradrenaline and reactivity to exogenous noradrenaline in normotensive subjects. 2. The relationship between plasma noradrenaline and reactivity was disturbed in age-matched patients with essential hypertension. 3. A multiple-regression analysis showed a highly significant correlation between adrenergic activity and reactivity to noradrenaline and the mean arterial blood pressure level (r = 0·91). The results suggest that adrenergic activity and pressor response to noradrenaline combined are important determinants of arterial blood pressure. 4. An inverse relationship could also be demonstrated between plasma renin activity and reactivity…

Tiesneša objektivitātes un neitralitātes kritērijs, vērtējot tiesneša saites ar kādu no pusēm

2018

Atbilstoši tiesneša ētikas normām tiesnesim jāpilda tiesu varas uzliktie pienākumi objektīvi un taisnīgi, līdz ar to nozīmīga ir tiesas un tiesnešu neatkarība no procesa dalībniekiem jeb personiskā neatkarība. Tiesneša objektivitāte un neitralitāte neaprobežojas tikai ar likumā uzskaitītajiem apstākļiem, kas ir pamats tiesneša atstatīšanai vai noraidīšanai, bet, izvērtējot objektivitāti, var ietvert arī jebkurus citus apstākļus, kas pamatoti var novest pie tiesneša objektivitātes un neitralitātes trūkuma. Darba mērķis ir analizēt tiesneša ētikas regulējumu un normatīvos aktus par tiesneša atstatīšanos un noraidījumu civillietās, kā arī apskatīt gadījumus, ko normatīvie akti neregulē, bet pē…

From the Golgi-Cajal mapping to the transmitter-based characterization of the neuronal networks leading to two modes of brain communication: Wiring a…

2007

After Golgi-Cajal mapped neural circuits, the discovery and mapping of the central monoamine neurons opened up for a new understanding of interneuronal communication by indicating that another form of communication exists. For instance, it was found that dopamine may be released as a prolactin inhibitory factor from the median eminence, indicating an alternative mode of dopamine communication in the brain. Subsequently, the analysis of the locus coeruleus noradrenaline neurons demonstrated a novel type of lower brainstem neuron that monosynaptically and globally innervated the entire CNS. Furthermore, the ascending raphe serotonin neuron systems were found to globally innervate the forebrai…

Effects of different levels of nitrogen on production and quality of strawberries from fresh "plug plants"

2012

Nitrogen is an essential element, not only for its influence on the vegetativeproductive activity of the plants but also on fruit quality (color, shelf life, etc.). To achieve high production and quality standards, reducing environment impact, the S.Ag.A Department of Palermo carried out some researches to identify the most suitable fertilization to maximize the productive potential of fresh plug plants of two cultivars of strawberry widespread in the Sicilian area, 'Sabrosa®Candonga' and 'Nora', reducing Nitrogen inputs. The experimental design adopted was a splitplot, in which the main plot was the different doses of nitrogen, 120, 170, 220, 270, 320 kg/ha and the secondary one the cultiv…

Nicotine receptors do not modulate the 3H-noradrenaline release from the isolated rat heart evoked by sympathetic nerve stimulation.

1982

Isolated rat hearts with the right sympathetic nerves attached were perfused at a constant flow rate of 7 ml/min with Tyrode's solution. (-)-3H-Noradrenaline (final concentration 10–13.9 nM) was infused for 10 min to label the noradrenaline stores. After wash-out the sympathetic nerves were stimulated electrically (3 Hz, 180 impulses, 1 ms, 20–30 mA) three times (S1–S3) at intervals of 15 min. 3H-Noradrenaline and its metabolites were determined by liquid scintillation counting according to Graefe et al. (1973). Both, nicotine 50 μM and p-aminophenethyltrimethylammonium (PAPETA) 30 μM, enhanced the 3H-noradrenaline overflow in the absence of nerve stimulation. The effect of PAPETA was bipha…

Evaluación del efecto de duloxetina y pregabalina en un modelo de fibromialgia inducida por reserpina en rata

2017

INTRODUCCIÓN El síndrome de fibromialgia (FMS) es una enfermedad que se caracteriza principalmente por dolor muscular crónico generalizado o multifocal de origen desconocido, y la co-existencia de otras manifestaciones clínicas, como las alteraciones del estado de ánimo, los trastornos del sueño, la fatiga, la rigidez matutina, las disfunciones cognitivas, la ansiedad, los dolores de cabeza recurrentes, los mareos, el síndrome de colon irritable y/o el dolor urogenital. La alta prevalencia de este síndrome en la población general plantea un problema social y económico, además, la complejidad de su diagnóstico y la falta de eficacia y efectividad de los tratamientos farmacológicos evidencia …

Sympathetic nervous activity and the pressor effect of noradrenaline under chronic?-?-adrenoceptor blockade with labetalol in hypertension

1983

In 14 patients with essential hypertension, the influence of the alpha- and beta-adrenoceptor blocking drug labetalol on blood pressure, heart rate, plasma renin, plasma noradrenaline and pressor effect of exogenous noradrenaline was investigated during long-term treatment. During the initial four weeks of treatment, labetalol at a dose of 400 mg/day showed a slight effect only on supine blood pressure, whereas upright blood pressure was already lowered effectively after the second week of treatment (p less than 0.01). An increase in the mean dose to 850 mg/day had an additional blood pressure-lowering effect (p less than 0.001), whereby a preferential decrease of the orthostatic blood pres…

Role of calcineurin in Ca2+-induced release of catecholamines and neuropeptides

1998

Neurotransmission requires rapid docking, fusion, and recycling of neurotransmitter vesicles. Several of the proteins involved in this complex Ca2+-regulated mechanism have been identified as substrates for protein kinases and phosphatases, e.g., the synapsins, synaptotagmin, rabphilin3A, synaptobrevin, munc18, MARCKS, dynamin I, and B-50/GAP-43. So far most attention has focused on the role of kinases in the release processes, but recent evidence indicates that phosphatases may be as important. Therefore, we investigated the role of the Ca2+/calmodulin-dependent protein phosphatase calcineurin in exocytosis and subsequent vesicle recycling. Calcineurin-neutralizing antibodies, which blocke…
