Psychotropic Effect of Combined Estrogen-Vit B6 Treatment in Endogenously Depressed Females

1985

Estrogens are among the most commonly prescribed substances in females. Also endogenous estrogen levels change dramatically throughout life and this biological variable has been associated with several psychological signs like premenstrual tension syndrome and depression in older age. Along with clinical practice there is increasing evidence from neuropharmacology suggesting a psychotropic action of estrogens (review: Holsboer, 1982). The most prominent findings are: 1. Reduction of monoamine-oxidase (MAO)-activity by estrogens (McEwen et al., 1978); 2. Competitive inhibition of catechol-o-methyltransferase by 2-hydroxyestrogens, which are major metabolites of estrogens in the CNS (Breuer e…

The Effects of Epinine on Arterial Blood Pressure and Regional Vascular Resistances in Anesthetized Rats

1998

1. We carried out experiments in anesthetized rats to study the hemodynamic effects of intravenous injections of epinine. 2. Epinine (1-320 micrograms/kg) produced a biphasic effect on mean arterial blood pressure (n = 30). At doses lower than 40 micrograms/kg, arterial blood pressure decreased (by as much as 21.5 +/- 3.4%), though at higher doses it increased dose dependently (by as much as 73.2 +/- 14.5%). Epinine also produced bradicardia in a dose-dependent manner (by as much as 26.4 +/- 4.9%). Sulpiride (100 micrograms/kg) suppressed the hypotensive effect of epinine but did not change the hypertensive effect. In the presence of prazosin (1,000 micrograms/kg), arterial blood pressure r…

<p>Clinical Evaluation of Everolimus in the Treatment of Neuroendocrine Tumors of the Lung: Patient Selection and Special Considerations. A Sys…

2020

Abstract Neuroendocrine tumors (NETs) of the lung are well-differentiated neuroendocrine neoplasms (NENs) with a heterogeneous clinical behaviour. Unlike gastroenteropancreatic NENs where therapeutic armamentarium clearly increased over the last decade, everolimus represented the only clinical practical innovation for lung NET patients over the last years. Therefore, for lung NETs, a multidisciplinary discussion within a dedicated team remains critical for an adequate decision-making. Although the main regulatory authorities considered the everolimus-related evidence is enough to approve the drug in advanced lung NETs, several clinical features deserve to be discussed. In this review, we sy…

Use of a three-factor interpretive optimisation strategy in the development of an isocratic chromatographic procedure for the screening of diuretics …

2000

Screening of diuretics in urine is feasible through direct injection of the samples into the chromatographic system and isocratic reversed-phase liquid chromatography (RPLC) with micellar-organic mobile phases of sodium dodecyl sulfate (SDS) and 1-propanol. The surfactant coverage of the chromatographic column makes the addition of organic competing amines less necessary than in conventional aqueous-organic RPLC to achieve well-shaped peaks. Also, the range of elution strengths of micellar mobile phases required to elute mixtures of hydrophobic and hydrophilic diuretics is smaller. This allows the isocratic separation of the diuretics within adequate analysis times. An interpretive methodol…

Neuroinflammatory and behavioral susceptibility profile of mice exposed to social stress towards cocaine effects.

2021

Using the social defeat (SD) model, numerous studies have shown that stressed mice display an enhanced response to the motivational effects of cocaine in the self-administration (SA) and conditioned-place preference (CPP) paradigms. However, not all subjects exposed to stress express its harmful effects. Some are particularly susceptible to the deleterious effects of repeated SD, while resilient mice successfully cope with stressful experiences and display adjusted psychological functioning after stress. Vulnerability to develop stress-related disorders, such as depression, has been linked to coping strategies and more recently to individual differences in the immune system. However, no stu…

Kinetic properties of catecholoxidase activity of tarantula hemocyanin

2008

Phenoloxidases occur in almost all organisms, being essentially involved in various processes such as the immune response, wound healing, pigmentation and sclerotization in arthropods. Many hemocyanins are also capable of phenoloxidase activity after activation. Notably, in chelicerates, a phenoloxidase has not been identified in the hemolymph, and thus hemocyanin is assumed to be the physiological phenoloxidase in these animals. Although phenoloxidase activity has been shown for hemocyanin from several chelicerate species, a characterization of the enzymatic properties is still lacking. In this article, the enzymatic properties of activated hemocyanin from the tarantula Eurypelma californi…

Sintesis de isoquinoleinas dopaminérgicas y de indenopiridinas melatoninérgicas

2014

El primer capítulo de la presente Tesis Doctoral versa sobre la síntesis de isoquinoleinas, concretamente Bencil-Isoquinoleinas halogenadas. Con dicha síntesis se pretende valorar la afinidad existente con el receptor dopaminérgico. En la presente tesis se describe tanto la síntesis detallada de este tipo de moléculas como los ensayos realizados de afinidad por los receptores dopaminérgicos o ensayos de binding. Por otra parte, se describe de forma más somera la síntesis de Butil-Isoquinoleinas quirales que han sido sintetizadas por el departamento de Quimica Organica de esta Universidad con el objetivo de posteriormente y realizando ensayos de binding dopaminérgico, ver la afinidad existen…

When Night Passes and When Day Breaks – Between the Past and the Present. Borderlines of Holocaust in Filip David’s Works

2017

Podstawowym celem tekstu jest analiza najnowszej tworczości Filipa Davida, autora nagrodzonej Nagrodą Tygodnika NIN („Nedeljne Informativne Novine") powieści Dom pamięci i zapomnienia (2014, Kuća sećanja i zabovrava). Z jednej strony twórczość serbskiego prozaika interesować nas będzie jako kontynuacja i reprezentacja współczesnego dyskursu na temat Holokaustu w Serbii. Z drugiej zaś – przyjrzymy się jego literackiej realizacji. Na przykładzie losów głównych bohaterów powieści (dzieci, które przeżyły Zagładę) pokażemy, gdzie przebiega rysowana przez autora granica istnienia Shoah w ich życiu. Na ile i w jaki sposób przeszłość wpływa na ich teraźniejszość, gdzie przebiega granica pamięci, ni…

Pierwszy prezydent. Kształtowanie obrazu Gabriela Narutowicza w pamięci i świadomości historycznej społeczeństwa polskiego. Kilka przykładów z tysiąca

2021

Celem artykułu jest przedstawienie działań podejmowanych na rzecz upamiętnienia postaci Gabriela Narutowicza, pierwszego prezydenta w historii Polski i związanego z tym procesu kształtowania jego wizerunku w pamięci i świadomości historycznej Polaków. Gabriel Narutowicz wybrany na urząd prezydenta w grudniu 1922 r. został zamordowany przez Eligiusza Niewiadomskiego, zaledwie tydzień po elekcji i drugim dniu urzędowania. Śmierć głowy państwa była kulminacją ostrej walki politycznej, która toczyła się na polskiej scenie politycznej w 1922 r. Bezpośrednio po zabójstwie, prezydent G. Narutowicz stał się dla części środowisk politycznych w Drugiej Rzeczypospolitej symboliczną ofiarą polskiego na…
