Has Multiculturalism Failed in Europe? Migration Policies, State of Emergency, and Their Impact on Migrants’ Identities in Italy

2014

This chapter analyzes migration policies in Italy within the larger frame of the debate on multiculturalism and its failure in Europe. The first part focuses on the exceptional flow of migrants that after the recent conflicts in Northern Africa was directed toward Europe across the Italian coast. The emergency raised issues for the defense of territories, social security, and preservation of identity. The author demonstrates the inefficiency of the Italian migration and emergency policies that has been adopted at the arrival of undocumented migrants from Northern Africa in 2011. The chapter uses the case of Italy to show the weakness of Europe in developing effective forms of coexistence an…

Yearly quotas and country-reserved shares in Italian immigration policy

2008

Regular immigration to Italy is based on a quota system setting annual ceilings to legal entries. Reserved shares are granted to single countries or categories of countries. Reserved shares have been increased; they are used as an incentive to obtain the cooperation of countries of origin in stemming irregular migration flows. The total quota of regular immigration has gradually increased too. Still, it does not fully respond to the growing demand of foreign workers on the labour market, and quotas seem to be used as crypto-regularisations rather than as an instrument for regulating legal entries.

Transient focal cerebral ischemia significantly alters not only EAATs but also VGLUTs expression in rats: relevance of changes in reactive astroglia

2010

The involvement of plasma membrane glutamate transporters (EAATs - excitatory aminoacid transporters) in the pathophysiology of ischemia has been widely studied, but little is known about the role of vesicular glutamate transporters (VGLUTs) in the ischemic process. We analyzed the expression of VGLUT1-3 in the cortex and caudate-putamen of rats subjected to transient middle cerebral artery occlusion. Western blot and immunohistochemistry revealed an increase of VGLUT1 signal in cortex and caudate-putamen until 3 days of reperfusion followed by a reduction 7 days after the ischemic insult. By contrast, VGLUT2 and 3 were drastically reduced. Confocal microscopy revealed an increase in VGLUT2…

Immunology of dermatophytosis

1983

By causing experimental lesions of dermatophytosis in rabbits inoculated and reinoculated with T. mentagrophytes var. granulosum and T. rubrum a study was carried out of the state of cellular immunity response, during infection, and also of the antigens responsible for the sensitization. Cellular immunity response was detected using the leucocyte migration test (L.M.T.) in the presence of antigenic compounds of the 'Keratinase' of Eleuterio et al.

Retinoid X receptor agonists impair arterial mononuclear cell recruitment through peroxisome proliferator-activated receptor-γ activation.

2012

Abstract Mononuclear cell migration into the vascular subendothelium constitutes an early event of the atherogenic process. Because the effect of retinoid X receptor (RXR)α on arterial mononuclear leukocyte recruitment is poorly understood, this study investigated whether RXR agonists can affect this response and the underlying mechanisms involved. Decreased RXRα expression was detected after 4 h stimulation of human umbilical arterial endothelial cells with TNF-α. Interestingly, under physiological flow conditions, TNF-α–induced endothelial adhesion of human mononuclear cells was concentration-dependently inhibited by preincubation of the human umbilical arterial endothelial cells with RXR…

Studies on the mechanism of PMN activation III. by lymphokines.

1983

The influence of a guinea pig lymphokine preparation on the oxidative metabolism of human and guinea pig granulocytes of various sources was investigated. A dose-dependent increase of the oxidative burst following lymphokine challenge was observed. It occurred in unstimulated guinea pig peripheral polymorphonuclear leukocytes (PMN) and in prestimulated PMN obtained from the peritoneal cavity after glycogen injection as well. The lymphokine effect on the oxidative metabolism is not species-restricted because the guinea pig lymphokine preparation elicits an oxidative burst in human PMN, too. The increase caused by lymphokines is nearly of the same order of magnitude as that obtained with zymo…

Cytokine components and mucosal immunity in the oviduct of Xenopus laevis (amphibia, pipidae)

2011

Abstract Most studies on the mucosal immunity in female reproductive tissues have been performed in mammals. In all species, apart from their reproductive strategies, immunity in the genital mucosa is required to defend the host against luminal pathogens. In this study we investigated the role of the innate immunity of the oviductal mucosa of Xenopus laevis , an amphibian characterized by external fertilization. In particular we examined the expression and localization of Interleukin-1β (IL1B), Macrophage migration inhibitory factor (MIF) and Interleukin-1 receptor type 1 (IL1R1) in different oviductal portions including an upper glandular region, an intermediate and a lower aglandular regi…
