Proliferative effect of acetylcholine on rat trachea epithelial cells is mediated by nicotinic receptors and muscarinic receptors of the M1-subtype.
2003
Acetylcholine (ACh), synthesized in mammalian non-neuronal cells such as epithelial cells of the airways, digestive tract and skin, is involved in the regulation of basic cell functions (so-called non-neuronal cholinergic system). In the present experiments rat trachea epithelial cells have been cultured to study the proliferative effect of applied ACh by [3H]thymidine incorporation. ACh (exposure time 24 h) caused a concentration-dependent increase in cell proliferation with a doubling of the [3H]thymidine incorporation at a concentration of 0.1 microM. This effect was partly reduced by 30 microM tubocurarine and completely abolished by the additional application of 1 microM atropine. The …

Distinct Incidence of Takotsubo Syndrome Between Amyotrophic Lateral Sclerosis and Synucleinopathies : A Cohort Study
2018
Takotsubo syndrome (TTS) is an acute cardiac syndrome characterized by regional left ventricular dysfunction with a peculiar circumferential pattern, which typically results in apical ballooning. Evidence indicates a pivotal role of catecholamines in TTS, and researchers have discussed multiple hypotheses on the etiology, including multivessel coronary spasm, myocardial stunning, excessive transient ventricular afterload, and cardiac sympathetic overactivity with local noradrenaline spillover. Although central nervous system disorders, such as stroke and epilepsy, are known to trigger TTS, the incidence and clinical features of TTS in neurodegenerative disorders are poorly understood. Here,…
METHADONE VERSUS BUPRENORPHINE: DATA DETECTED FROM CALTANISSETTA SER.T
2018
In last years, heroin-addicted have exponentially increased: this has made it necessary to identify a pharmacological strategy as effective as possible. With this purpose, a statistical investigation was conducted in a sample of individuals, aged between 18 and 50. They were diagnosed and subjected to different treatments at Ser.T of Caltanissetta (Sicily-Italy) during the period 2013-2017. The analyzed patients were treated with three different pharmacological therapy: methadone 0.1%, methadone 0.5%, buprenorphine and suboxone. We obtained percentages of RESPONDERS, LOW RESPONDERS and NON RESPONDERS patients from data processing, based on used therapy. Considering pharmacological responses…
No phylogeographic structure in the circumpolar snowy owl (Bubo scandiacus)
2008
The snowy owl (Bubo scandiacus) is a nomadic species with a circumpolar distribution. It has recently declined in the western Palearctic and may thus be worthy of special consideration for conservation. We investigated genetic structure in three well separated geographic regions within the snowy owls’ breeding range. We sequenced two mitochondrial genes; the control region and cytochrome b, and two Z-chromosome introns; VLDLR-9 and BRM-15. We found no phylogeographic structure among the sampled regions, indicating high levels of gene flow in the recent past and possibly still today. Intra-population diversity did not vary between regions for the control region, but for Cyt b, North American…
Multifunctional hybrid nanocomposites based on carbon nanotubes and chemically modified graphene
2013
La Tesis trata del desarrollo de materiales híbridos multifuncionales basados en nanotubos de carbono y grafeno con interés en magnetismo molecular y electrónica molecular This Thesis deals with the chemistry and development of new hybrid multifunctional systems based on carbon nanotubes (CNTs) and graphene (G). To introduce both types of carbon nanoforms a brief historical overview of these systems has been briefly given at the Preface. Next and prior to the presentation of the results, two introductory chapters in which the principal aspects of the synthesis, properties and applications of carbon nanotubes (chapter 1) and graphene (chapter 2) are given. The results have been divided in th…
Potential of using data assimilation to support forest planning
2017
Uncertainty in forest information typically results in economic and ecological losses as a consequence of suboptimal management decisions. Several techniques have been proposed to handle such uncertainties. However, these techniques are often complex and costly. Data assimilation (DA) has recently been advocated as a tool that may reduce the uncertainty, thereby improving the quality of forest planning results. It offers an opportunity to make use of all new sources of information in a systematic way and thus provides more accurate and up-to-date information to forest planning. In this study, we refer to literature on handling uncertainties in forest planning, as well as related literature …
Transfery poselskie jako źródło nowych inicjatyw politycznych
2017
Partie polityczne – zgodnie z klasycznym ujęciem M. Duvergera – powstają według wewnętrznego i zewnętrznego trybu. Celem niniejszego artykułu jest analiza powstawania partii politycznych w Polsce zgodnie z pierwszym trybem (wewnętrznym), wykorzystując do tego koncept „transferu parlamentarnego”, tj. zmian przynależności klubowej posłów skutkujących powstaniem nowej partii politycznej.
Podporządkowanie technologiczne w zatrudnieniu
2022
The employee is not, as yet, separated from the working environment by their 'humanity'. The working environment becomes a kind of network, connected to other employees and the enterprise through invisible threads of dependencies and influences woven from personal data that can be algorithmically arranged and given new meaning and ownership. Authority and subordination are their physical representations. These interdependencies have one thing in common, regardless of the type of organised complexity. Each employee is equally subjected to informational authority, regardless of their profession, tion and industry. Everywhere, they are equally networked, subject to the same pressure and superv…
Desarrollo de metodologías sostenibles de análisis
2017
Uno de los retos actuales en la Química Analítica reside en el desarrollo de metodologías analíticas sostenibles que respeten los principios planteados por la Química Verde, de manera su impacto sobre el entorno sea mínimo. Para conseguir este objetivo se han establecido diferentes estrategias o líneas de investigación. En primer lugar, las técnicas de microextracción están aportando numerosas ventajas, aunque todavía presentan algunas limitaciones. Por consiguiente, resulta necesario desarrollar técnicas que automaticen la etapa relativa al pretratamiento de la muestra con el fin de disminuir tanto el tiempo de análisis como la manipulación de la muestra. En segundo lugar, y atendiendo a l…
