Formation and release of acetylpyrrolidinecholine (N-methyl, N-acetoxyethylpyrrolidinium) as a false cholinergic transmitter in the myenteric plexus …
1977
1. Longitudinal muscle strips of the guineapig small intestine were incubated with Tyrode solution containing the choline analogue pyrrolidinecholine. At the end of the incubation the concentrations of acetylcholine and its analogue acetylpyrrolidinecholine were determined in the strips by gas chromatography. 2. After 120 min of incubation with 1 mM pyrrolidinecholine, acetylpyrrolidinecholine comprised about 15% of the total amount of acetylcholine plus acetylpyrrolidinecholine. Electrical stimulation (1 Hz) of the strips during the incubation slightly increased the proportion of acetylpyrrolidinecholine to 21%. 3. The acetylcholine content of control strips increased significantly during …
The effects of methacholine and calcium deprivation on the release of the false transmitter, ?-methyladrenaline, from the isolated rabbit heart
1976
1. Anaesthetized rabbits were infused for 20 min with 85 μg · kg−1 · min−1 (±)-α-methyladrenaline. The hearts dissected 15 min after the infusion contained 1.49 μg/g α-methyladrenaline; the endogenous noradrenaline content was correspondingly decreased. 2. Hearts from α-methyladrenaline-infused animals were isolated with the right sympathetic nerves intact and perfused. Ventricular rate, right atrial and right ventricular tensions were recorded using the transverse method. 3. Electrical stimulation (10 Hz, 1 ms, 1 min) of sympathetic nerves, perfusion with the nicotinic drug, p-aminophenethyltrimethylammonium (PAPETA) or perfusion with 54 mM KCl (high K+) solution evoked an output of both α…
6-Hydroxydopamine lesioning differentially affects α-synuclein mRNA expression in the nucleus accumbens, striatum and substantia nigra of adult rats
2002
The effect of a unilateral 6-hydroxydopamine (6-OHDA) lesion and/or repeated administration of levodopa (L-DOPA) to normal and 6-OHDA-lesioned rats on alpha-synuclein mRNA expression was investigated by in situ hybridization histochemistry. A 6-OHDA lesion of the nigro-striatal pathway alone, confirmed by the loss of nigral tyrosine hydroxylase mRNA expression, markedly decreased alpha-synuclein mRNA in the lesioned substantia nigra (SN). In contrast, the levels of alpha-synuclein mRNA in the denervated striatum and nucleus accumbens were not altered. Chronic administration of L-DOPA to normal or 6-OHDA-lesioned rats had no effect on alpha-synuclein mRNA expression in the SN, striatum or nu…
L’altare di Maria Santissima del Lume nella chiesa delle Anime Sante a Valletta.
2015
Il contributo si occupa di ricostruire, attraversi documenti finora mai pubblicati, le vicende realizzative relative all'inedito altare maggiore della chiesa delle Anime Sante a Valletta (Malta), opera dei maestri marmorari messinesi Antonino e Francesco Amato e aiuti degli anni 1743-1747. The essay, through documents never before published, speaks of the events related to the construction of the main altar of the church of the Holy Souls in Valletta (Malta). It is a work of the marble workers Antonino and Francesco Amato and aid from Messina made in the years 1743-1747.
Questions de sainteté : vicissitudes des reliques dans le diocèse d'Autun au Moyen Âge
2006
The recent purchase of an authentic manuscript from Flavigny abbey referring to the translation of saints bodies gives an opportunity to assess significiance of relics into the cult of saints in the diocese of Autun (Burgundy) during the Middle Ages. Several data source of piety esspecially dedications, religious references in diplomatic acts, and calendars, gives an evidence of the evolution of devotion and even the recession of some cults among several clerics groups. Besides, those informations show the incidence of the cult of regional saints in construction of Autun diocese, wich is one of the larger dioceses in Burgundy.
Die Hemmbarkeit der inhibitorischen Adrenalinbzw. Noradrenalinwirkung durch Adrenolytika
1958
Dibenamine, dihydroergotamine, regitin and priscol were found to antagonize specifically the inhibitory action of adrenaline and noradrenaline on the electrically stimulated isolated ileum of the guinea-pig. The antagonistic action of dibenamine was irreversible.
Der Antagonismus verschiedener Sympatholytica gegen�ber dem inhibitorischen Adrenalin- oder Noradrenalineffekt am elektrisch gereizten Meerschweinche…
1958
Adrenaline and noradrenaline were found to depress the contractions of the electrically stimulated isolated ileum of the guinea-pig; this action was related to the dose. In these experiments smaller amounts of adrenaline were required than those necessary for the depression of the spontaneous movements of the isolated rabbit duodenum.
Functional consequences of prejunctional receptor activation or blockade in the iris.
1994
The iris is innervated by nerves of the sympathetic, parasympathetic, and sensory nervous systems. The terminal nerve fibres are endowed with prejunctional receptors which modulate neurotransmitter release. Activation or blockade of prejunctional receptors by drugs may have an influence on iris smooth muscle tone. Several findings are in favour of the hypothesis that prejunctional receptors may be involved in regulation of iris smooth muscle tone and/or pathophysiological events. (i). Release of acetylcholine from parasympathetic nerves of guinea-pig iris sphincter evoked by electrical stimulation is subject to autoinhibition via prejunctional M2 muscarinic receptors, and the release can be…
Production and physicochemical characterization of a new amine derivative of gellan gum and rheological study of derived hydrogels
2020
The production of an amine derivative of gellan gum, named GG-EDA, was here obtained by functionalizing the polysaccharide backbone with pendant ethylenediamine moieties. The obtained derivative was characterized by spectroscopic, colorimetric, chromatographic and rheological analyses to study the effect of the free amino groups on the physicochemical properties of the macromolecule. A titration experiment was conducted to study the acid-base dissociation constants in aqueous media for the carboxylic and amino groups in the GG-EDA and to shed light on the possibility that the derivative shows a polyampholyte structure under physiological conditions. The rheological analysis conducted on bot…
