Anti-inflammatory Function of High-Density Lipoproteins via Autophagy of IκB Kinase
2015
Background & Aims: Plasma levels of high-density lipoprotein (HDL) cholesterol are frequently found decreased in patients with inflammatory bowel disease (IBD). Therefore, and because HDL exerts anti-inflammatory activities, we investigated whether HDL and its major protein component apolipoprotein A-I (apoA-I) modulate mucosal inflammatory responses in vitro and in vivo. Methods: The human intestinal epithelial cell line T84 was used as the in vitro model for measuring the effects of HDL on the expression and secretion of tumor necrosis factor (TNF), interleukin-8 (IL-8), and intracellular adhesion molecule (ICAM). Nuclear factor-κB (NF-κB)-responsive promoter activity was studied by …
Theoretics and Methodology
2016
Since 2000 in Europe an integrated management framework has been developed to innovate exploitation and safeguard of water resources. In this context the EU Water Framework Directive has identified the hydrographic basin as the optimal territorial unit for promoting new participatory policies, based both on the interaction of stakeholders and the coordination of sectorial instruments. In this scenario, river contracts assumed a strategic role both in addressing these purposes and supporting the dialogue and integration between interests of public and private stakeholders. This chapter illustrates the theoretical and methodological framework, and the comparative approach on which the researc…
Air monitoring of selected volatile organic compounds in wineries using passive sampling and headspace-gas chromatography–mass spectrometry
2014
Abstract Volatile compounds released during the production of wine at different steps of the winemaking process were evaluated using semipermeable membranes based passive samplers. Preliminary data on the differences between five wine varieties were provided together with the indoor quality of air to which winery workers are exposed during their professional activity. A simple, green and fast analytical methodology was employed for the direct analysis of deployed samplers by using head space (HS) gas chromatography–mass spectrometry (GC–MS) without any sample pre-treatment and avoiding the use of solvents. Terpenes as styrene, pinene, p-cymene and limonene were found at concentration levels…
Work, power and learning in a risk filled occupation
2011
In this article we describe various ways in which power is exercised between personnel in a hospital operating theatre. We aim to investigate how the forms of discursive power and workplace learning are intertwined with each other by utilizing an ethnographic approach in the fieldwork. Our data were collected mainly through observations and interviews with surgical residents, physicians and nurses. In the article we describe the delicate ways in which power is exercised and resisted in everyday practices. We argue that there is a close relationship between learning and manifestations of power, together with the various forms of these manifestations and the restrictions that may be placed o…
Zabezpieczenie na nieruchomości w postępowaniu karnym jako wyraz równorzędności reguł interpretacji w praktyce orzeczniczej sądu karnego
2021
Artykuł poddaje analizie instytucję zabezpieczenia na nieruchomości w postępowaniu karnym w kontekście połączenia w niej działania organów postępowania karnego w dwóch różnych procedurach i w dwóch różnych pozycjach procesowych. Zabezpieczenie następuje w zakresie tytułu wykonawczego w postaci stosownego postanowienia i wynika z postępowania karnego w fazie in personam. Tytuł wykonawczy uzyskany w procedurze karnej stanowi podstawę wpisu hipoteki przymusowej według regulacji procedury cywilnej do księgi wieczystej. Artykuł ma na celu przedstawienie powyższej problematyki w kontekście rozkładu ciężaru argumentacyjnego poszczególnych uczestników dyskursu wskazanej sytuacji procesowej, a także…
Optical diagnostic method for benzene detection in air
2014
In this paper we show our first results of research for creation a detector for benzene vapor and possibly other volatile organic compounds detection in air based on Zeeman atomic absorption technique. First the detailed study of benzene absorption spectra with high resolution spectrometer Jobin-Yvon 1000M was done. The absorption spectra of benzene were registered in the spectral range from 200-900 nm. More detailed analysis was done for the 240 – 260 nm spectral range to test a possibility to detect benzene by means of emission line of 254 nm of mercury.
Lo ZEN e l'arte della narrazione dei luoghi
2011
This paper aims at analysing a very well-known Italian neighbourhood, which is located in Palermo and called Zen. This neighbourhood has often been described as a clear example of the worst and most disgraced urban landscapes in Italy, as mass media and local stakeholders shaped its image for their own uses. Through a series of interviews, on-the-spot inspections and the use of other qualitative methodologies, the final goal of this paper is to subvert traditional representations of this place and enforce a plural way of describing it, using research techniques that might position the researcher and his or her own description inside a larger framework. Would geographers, social scientists a…
Sex roles during conspecific territorial defence in the Zenaida dove, Zenaida aurita
2012
Social monogamy in vertebrates often involves the joint defence of an all-purpose territory by pair members. Although both sexes presumably benefit from holding a territory, sex-related variation is often observed in territory defence at the interspecific level, particularly in birds. Most studies of territorial defence in monogamous birds, however, have been conducted on songbirds or on bird species living in temperate areas. In contrast, data on nonoscine tropical bird species remain scarce. We experimentally studied territorial defence in 20 pairs of Zenaida doves, a tropical and territorial monogamous bird species that maintains year-round pair bonds. Overall, males responded to intrusi…
Vigilance and food intake rate in paired and solitary Zenaida DovesZenaida aurita
2011
We quantified vigilance during feeding in the Zenaida Dove Zenaida aurita, a tropical species with stable pair-bonds and year-round territoriality. Both males and females decreased the proportion of time spent vigilant by 30% when feeding with their partner compared with when feeding alone. This reduction was achieved through increasing the length of inter-scan duration, while scan duration remained constant. No evidence was found for coordination of vigilance between pair members. The equal investment in vigilance by male and female Zenaida Doves might be related to the mutual benefits of long-term pair-bonding.

Research in avian behavioral ecology is affected by a known bias in favour of temperate species despite the greatest diversity of tropical species and the radically remote natural conditions which make knowledge of temperate species hardly relevant to tropical species.We propose to reduce the lack of information about tropical birds through the study of a socially monogamous species, reproducing and defending an all-purpose territory all year round, the Zenaida dove, Zenaida aurita. We used monitoring data from a population of ringed birds in Barbados for six years. First, we focused on plumage coloration both to ascertain their sexually mono- or dichromatic nature and whether plumage colou…
