Cellular and humoral immune responses against the Plasmodium vivax MSP-119 malaria vaccine candidate in individuals living in an endemic area in north-eastern Amazon region of Brazil

Abstract Background Plasmodium vivax merozoite surface protein-1 (MSP-1) is an antigen considered to be one of the leading malaria vaccine candidates. PvMSP-1 is highly immunogenic and evidences suggest that it is target for protective immunity against asexual blood stages of malaria parasites. Thus, this study aims to evaluate the acquired cellular and antibody immune responses against PvMSP-1 in individuals naturally exposed to malaria infections in a malaria-endemic area in the north-eastern Amazon region of Brazil. Methods The study was carried out in Paragominas, Pará State, in the Brazilian Amazon. Blood samples were collected from 35 individuals with uncomplicated malaria. Peripheral blood mononuclear cells were isolated and the cellular proliferation and activation was analysed in presence of 19 kDa fragment of MSP-1 (PvMSP-119) and Plasmodium falciparum PSS1 crude antigen. Antibodies IgE, IgM, IgG and IgG subclass and the levels of TNF, IFN-γ and IL-10 were measured by enzyme-linked immunosorbent assay. Results The prevalence of activated CD4+ was greater than CD8+ T cells, in both ex-vivo and in 96 h culture in presence of PvMSP-119 and PSS1 antigen. A low proliferative response against PvMSP-119 and PSS1 crude antigen after 96 h culture was observed. High plasmatic levels of IFN-γ and IL-10 as well as lower TNF levels were also detected in malaria patients. However, in the 96 h supernatant culture, the dynamics of cytokine responses differed from those depicted on plasma assays; in presence of PvMSP-119 stimulus, higher levels of TNF were noted in supernatant 96 h culture of malaria patient’s cells while low levels of IFN-γ and IL-10 were verified. High frequency of malaria patients presenting antibodies against PvMSP-119 was evidenced, regardless class or IgG subclass.PvMSP-119-induced antibodies were predominantly on non-cytophilic subclasses. Conclusions The results presented here shows that PvMSP-119 was able to induce a high cellular activation, leading to production of TNF and emphasizes the high immunogenicity of PvMSP-119 in naturally exposed individuals and, therefore, its potential as a malaria vaccine candidate.

Distribution of Rickettsia rickettsii in ovary cells of Rhipicephalus sanguineus (Latreille1806) (Acari: Ixodidae)

Abstract Background Considering the fact that the dog tick, Rhipicephalus sanguineus, has a great potential to become the vector of Brazilian Spotted Fever (BSF) for humans, the present study aimed to describe the distribution of the bacterium Rickettsia rickettsii, the etiological agent of BSF, in different regions of the ovaries of R. sanguineus using histological techniques. The ovaries were obtained from positive females confirmed by the hemolymph test and fed in the nymph stage on guinea pigs inoculated with R. rickettsii. Results The results showed a general distribution of R. rickettsii in the ovary cells, being found in oocytes in all stages of development (I, II, III, IV and V) most commonly in the periphery of the oocyte and also in the cytoplasm of pedicel cells. Conclusions The histological analysis of the ovaries of R. sanguineus infected females confirmed the presence of the bacterium, indicating that the infection can interfere negatively in the process of reproduction of the ticks, once alterations were detected both in the shape and cell structure of the oocytes which contained bacteria.

Oócitos aparentemente maduros injetados em telófase I apresentam piores resultados de reprodução assistida

OBJETIVO: Avaliar o estágio de maturação nuclear de oócitos com o primeiro corpúsculo polar (CP) visível de pacientes inférteis submetidas à estimulação ovariana para injeção intracitoplasmática de espermatozoide (ICSI) e comparar os resultados da injeção intracitoplasmática de espermatozoide entre os oócitos em telófase I (TI) e metáfase II (MII), e entre aqueles em metáfase II com e sem fuso celular visível. MÉTODOS: Estudo prospectivo que incluiu 106 pacientes inférteis submetidas à injeção intracitoplasmática de espermatozoide. Foram incluídas pacientes com idade menor ou igual a 38 anos, hormônio folículo estimulante (FSH) basal menor que 10 mIU/mL e índice de massa corpórea (IMC) menor que 30 kg/m². Foram excluídas pacientes com doenças sistêmicas, com qualquer infecção ativa, tabagistas ou que fizeram uso de medicações hormonais e anti-inflamatórias hormonais e não hormonais nos últimos dois meses, previamente à programação para o procedimento de reprodução assistida. Os oócitos com extrusão do primeiro corpúsculo polar foram avaliados pela microscopia de polarização, imediatamente antes da realização da injeção intracitoplasmática de espermatozoide, e caracterizados quanto ao estágio de maturação nuclear (telófase I ou metáfase II). Os oócitos em metáfase II foram avaliados de acordo com a presença ou não do fuso meiótico. Foram analisadas as taxas de fertilização, clivagem e o número de embriões de boa qualidade no segundo dia (D2) de desenvolvimento. Os dados foram analisados comparativamente através do teste exato de Fisher. Em todas as análises foi considerado o nível de significância de 5% (p<0,05). RESULTADOS: O fuso meiótico de 516 oócitos foi visualizado através da microscopia de polarização. Dezessete dos 516 oócitos avaliados estavam em telófase I (3,3%) e 499 (96,7%) em metáfase II. Os oócitos injetados em telófase I apresentaram taxas de fertilização significativamente menores do que os injetados em metáfase II (53 e 78%, respectivamente) e não produziram nenhum embrião de boa qualidade no segundo dia. Comparando-se os oócitos com e sem fuso celular visível, não foi observada diferença significativa nos resultados de injeção intracitoplasmática de espermatozoide. CONCLUSÕES: Oócitos injetados em telófase I apresentaram menores taxas de fertilização quando comparados aos em metáfase II. É possível que a análise do estágio de maturação nuclear oocitária, por meio da microscopia de polarização, possa ser utilizada como fator de predição das taxas de fertilização pós-injeção intracitoplasmática de espermatozoide.

Análise invasiva e não invasiva do fuso meiótico de oócitos humanos obtidos de ciclos estimulados: dados preliminares

OBJETIVOS: Avaliar a concordância entre as técnicas de microscopia de polarização e microscopia confocal na avaliação do fuso meiótico de oócitos humanos maturados in vivo. MÉTODOS: Estudo prospectivo que avaliou oócitos com o primeiro corpúsculo polar extruído obtidos de mulheres inférteis submetidas à estimulação ovariana para realização de injeção intracitoplasmática de espermatozoide. Os oócitos com o primeiro corpúsculo polar extruído foram avaliados por meio da microscopia de polarização e, imediatamente após, foram fixados e corados para avaliação dos microtúbulos e cromatina pela microscopia confocal de alto desempenho. Foram comparadas as técnicas de microscopia de polarização e confocal, de acordo com a visualização ou não do fuso meiótico pela microscopia de polarização e a presença ou não de anomalias meióticas à análise pela microscopia confocal. Foram calculados os intervalos de confiança, o índice de Kappa e a concordância entre as metodologias, considerando a análise da microscopia de imunofluorescência como padrão-ouro para avaliação de normalidade do fuso e distribuição cromossômica oocitária. RESULTADOS: Observou-se que 72,7% dos oócitos em metáfase II com fuso celular não visível à polarização apresentaram anormalidades meióticas à análise confocal e que 55,6% dos oócitos em metáfase II com fuso celular visível à polarização apresentaram-se como oócitos anormais à análise confocal. Somente 44,4% dos oócitos com fuso celular visível à polarização apresentaram-se como normais à análise confocal. A concordância entre os métodos foi de 51,1% (Kappa: 0,11; IC95% -0,0958 - 0,319). CONCLUSÕES: A baixa concordância entre a microscopia de polarização e a confocal na avaliação do fuso meiótico oocitário sugere que a visualização do fuso meiótico de oócitos humanos em metáfase II pela microscopia de polarização tem limitado o valor preditivo de normalidade meiótica oocitária.

Iheringichthys syi (Siluriformes: Pimelodidae), a new pimelodid species from upper Paraná basin, Brazil

We describe a new species of pimelodid catfish of the genus Iheringichthys from the upper Paraná basin, Brazil. Iheringichthys syi n. sp. is distinguished by the comparatively fine serration along the anterior margin of the pectoral-fin spine, an adpressed dorsal-fin remote from the adipose-fin origin, a large eye (23.2-31.2% of head length), narrow interorbital (16.2-23.0% of head length), long snout (42.0-51.0% of head length), long postorbital length (30.6-34.0% of head length), low adipose fin (4.8-7.8% of standard length), eye diameter 97.0-140.0% of interorbital length, and body with numerous, small dots irregularly scattered on flanks, especially marked on anterior half of flank.

Relative CO2/NH3 permeabilities of human RhAG, RhBG and RhCG

Mammalian glycosylated rhesus (Rh) proteins include the erythroid RhAG and the nonerythroid RhBG and RhCG. RhBG and RhCG are expressed in multiple tissues, including hepatocytes and the collecting duct (CD) of the kidney. Here, we expressed human RhAG, RhBG and RhCG in Xenopus oocytes (vs. H2O-injected control oocytes) and used microelectrodes to monitor the maximum transient change in surface pH (ΔpHS) caused by exposing the same oocyte to 5 % CO2/33 mM HCO3 − (an increase) or 0.5 mM NH3/NH4 + (a decrease). Subtracting the respective values for day-matched, H2O-injected control oocytes yielded channel-specific values (*). (ΔpH∗S)CO2 and (−ΔpH∗S)NH3 were each significantly >0 for all channels, indicating that RhBG and RhCG—like RhAG—can carry CO2 and NH3. We also investigated the role of a conserved aspartate residue, which was reported to inhibit NH3 transport. However, surface biotinylation experiments indicate the mutants RhBGD178N and RhCGD177N have at most a very low abundance in the oocyte plasma membrane. We demonstrate for the first time that RhBG and RhCG—like RhAG—have significant CO2 permeability, and we confirm that RhAG, RhBG and RhCG all have significant NH3 permeability. However, as evidenced by (ΔpH∗S)CO2/(−ΔpH∗S)NH3 values, we could not distinguish among the CO2/NH3 permeability ratios for RhAG, RhBG and RhCG. Finally, we propose a mechanism whereby RhBG and RhCG contribute to acid secretion in the CD by enhancing the transport of not only NH3 but also CO2 across the membranes of CD cells.

Movement of NH3 through the human urea transporter B: a new gas channel

Aquaporins and Rh proteins can function as gas (CO2 and NH3) channels. The present study explores the urea, H2O, CO2, and NH3 permeability of the human urea transporter B (UT-B) (SLC14A1), expressed in Xenopus oocytes. We monitored urea uptake using [14C]urea and measured osmotic water permeability (Pf) using video microscopy. To obtain a semiquantitative measure of gas permeability, we used microelectrodes to record the maximum transient change in surface pH (∆pHS) caused by exposing oocytes to 5% CO2/33 mM HCO3- (pHS increase) or 0.5 mM NH3/NH4+ (pHS decrease). UT-B expression increased oocyte permeability to urea by >20-fold, and Pf by 8-fold vs. H2O-injected control oocytes. UT-B expression had no effect on the CO2-induced ∆pHS but doubled the NH3-induced ∆pHS. Phloretin reduced UT-B-dependent urea uptake (Jurea * ) by 45%, Pf * by 50%, and (- ∆pHS * )NH3 by 70%. p-Chloromercuribenzene sulfonate reduced Jurea * by 25%, Pf * by 30%, and (∆pHS * )NH3 by 100%. Molecular dynamics (MD) simulations of membrane-embedded models of UT-B identified the monomeric UT-B pores as the main conduction pathway for both H2O and NH3 and characterized the energetics associated with permeation of these species through the channel. Mutating each of two conserved threonines lining the monomeric urea pores reduced H2O and NH3 permeability. Our data confirm that UT-B has significant H2O permeability and for the first time demonstrate significant NH3 permeability. Thus the UTs become the third family of gas channels. Inhibitor and mutagenesis studies and results of MD simulations suggest that NH3 and H2O pass through the three monomeric urea channels in UT-B.

Photobiological effect of low-level laser irradiation in bovine embryo production system

The objectives of this study were to evaluate the effect of low-level laser irradiation (LLLI) on bovine oocyte and granulosa cells metabolism during in vitro maturation (IVM) and further embryo development. Cumulus-oocytes complexes (COCs) were subjected (experimental group) or not (control group) to irradiation with LLLI in a 633-nm wavelength and 1 J/cm2 fluency. The COCs were evaluated after 30 min, 8, 16, and 24 h of IVM. Cumulus cells were evaluated for cell cycle status, mitochondrial activity, and viability (flow cytometry). Oocytes were assessed for meiotic progression status (nuclear staining), cell cycle genes content [real-time polymerase chain reaction (PCR)], and signal transduction status (western blot). The COCs were also in vitro fertilized, and the cleavage and blastocyst rates were assessed. Comparisons among groups were statistically performed with 5% significance level. For cumulus cells, a significant increase in mitochondrial membrane potential and the number of cells progressing through the cycle could be observed. Significant increases on cyclin B and cyclin-dependent kinase (CDK4) levels were also observed. Concerning the oocytes, a significantly higher amount of total mitogen-activated protein kinase was found after 8 h of irradiation, followed by a decrease in all cell cycle genes transcripts, exception made for the CDK4. However, no differences were observed in meiotic progression or embryo production. In conclusion, LLLI is an efficient tool to modulate the granulosa cells and oocyte metabolism

Chemical Bonding of Hydrocarbons to Metal Surfaces

Using x-ray absorption spectroscopy (XAS), x-ray emission spectroscopy (XES) and x-ray photoelectron spectroscopy (XPS) in combination with density functional theory (DFT) the changes in electronic and geometric structure of hydrocarbons upon adsorption are determined. The chemical bonding is analyzed and the results provide new insights in the mechanisms responsible for dehydrogenation in heterogeneous catalysis. In the case of alkanes, n-octane and methane are studied. XAS and XES show significant changes in the electronic structure upon adsorption. XES shows new adsorption induced occupied states and XAS shows quenching of CH*/Rydberg states in n-octane. In methane the symmetry forbidden gas phase lowest unoccupied molecular orbital becomes allowed due to broken symmetry. New adsorption induced unoccupied features with mainly metal character appear just above the Fermi level in XA spectra of both adsorbed methane and n-octane. These changes are not observed in DFT total energy geometry optimizations. Comparison between experimental and computed spectra for different adsorbate geometries reveals that the molecular structures are significantly changed in both molecules. The C-C bonds in n-octane are shortened upon adsorption and the C-H bonds are elongated in both n-octane and methane. In addition ethylene and acetylene are studied as model systems for unsaturated hydrocarbons. The validity of both the Dewar-Chatt-Duncanson chemisorption model and the alternative spin-uncoupling picture is confirmed, as well as C-C bond elongation and upward bending of the C-H bonds. The bonding of ethylene to Cu(110) and Ni(110) are compared and the results show that the main difference is the amount of back-donation into the molecular π* orbital, which allows the molecule to desorb molecularly from the Cu(110) surface, whereas it is dehydrogenated upon heating on the Ni(110) surface. Acetylene is found to adsorb in two different adsorption sites on the Cu(110) surface at liquid nitrogen temperature. Upon heating the molecules move into one of these sites due to attractive adsorbate-adsorbate interaction and only one adsorbed species is present at room temperature, at which point the molecules start reacting to form benzene. The bonding of the two species is very similar in both sites and the carbon atoms are rehybridized essentially to sp2.

Dose-dependent effect of a single GnRHa injection on the spawning of meagre ("Argyrosomus regius") broodstock reared in captivity

[EN]The present study aimed to determine the spawning efficacy, egg quality and quantity of captive breed meagre induced with a single gonadotrophin-releasing hormone agonist (GnRHa) injection of 0, 1, 5, 10, 15, 20, 25, 30, 40 or 50 μg kg–1 to determine a recommended optimum dose to induce spawning. The doses 10, 15 and 20 μg kg–1 gave eggs with the highest quality (measured as: percentage of viability, floating, fertilisation and hatch) and quantity (measured as: total number of eggs, number of viable eggs, number of floating eggs, number of hatched larvae and number of larvae that reabsorbed the yolk sac). All egg quantity parameters were described by Gaussian regression analysis with R2 = 0.89 or R2 = 0.88. The Gaussian regression analysis identified that the optimal dose used was 15 μg kg–1. The regression analysis highlighted that this comprehensive study examined doses that ranged from low doses insufficient to stimulate a high spawning response (significantly lower egg quantities, p < 0.05) compared to 15 μg kg–1 through to high doses that stimulated the spawning of significantly lower egg quantities and eggs with significantly lower quality (egg viability). In addition, the latency period (time from hormone application to spawning) decreased with increasing doses to give a regression (R2 = 0.93), which suggests that higher doses accelerated oocyte development that in turn reduced egg quality and quantity. The identification of an optimal dose for the spawning of meagre, which has high aquaculture potential, represents an important advance for the Mediterranean aquaculture industry.

Struktur und Funktion des Lipoproteins von Nereis virens (Annelida)

Ein discoidales Lipoprotein aus dem Polychaeten Nereis virens (Annelida) wurde eingehend charakterisiert. Im Vordergrund standen dabei die transportierten Lipide, sowie die Ultrastruktur des Partikels. Das Nereis-Lipoprotein besitzt eine für Invertebraten atypische Lipidzusammensetzung: Außer den Phospholipiden gibt es keine klar dominierende Lipidklasse. Die Charakterisierung der Apolipoproteine zeigt Gemeinsamkeiten mit den Apolipophorinen der Insekten: Wie diese besitzt das Nereis-Lipoprotein zwei Apolipoproteine, die in einer 1:1-Stöchiometrie angeordnet sind. Das größere Protein (ApoNvLp I) ist dabei stärker zum wässrigen Medium exponiert ist als das kleinere (ApoNvLp II). Beide Proteinuntereinheiten sind N-glycosyliert. ApoNvLp II ist zusätzlich noch O-glycosyliert. Bei den Sekundärstrukturen dominieren β-Strukturen (35%) gegenüber α-Helices (14%); 28% waren ungeordnete Strukturen. Die Masse wurde mit verschiedenen Methoden bestimmt: sie liegt zwischen ~800 kDa (Gelfiltration) und ~860 kDa (Analytische Ultrazentrifugation). Der Sedimentationskoeffizient beträgt 9,7 S. Der zelluläre Lipoproteinrezeptor wurde aus einer großen Anzahl von Zellen und Geweben isoliert. Die biochemische Charakterisierung des Rezeptormoleküls zeigte es als ein monomeres, integrales, N- und O-glycosyliertes Membranprotein mit einer Masse von ~114 kDa. Die Bindungscharakteristika (Abhängigkeit von Ca2+, Disulfidbrücken) weisen es als Mitglied der LDLR-Superfamilie aus. In vitro-Inkubationsversuche mit fluoreszenzmarkierten Lipoproteinen zeigten die Aufnahme sowohl in Oocyten als auch in freie Coelomzellen (Elaeocyten) sowie in Spermatogonien- und Tetradenstadien. Auffällig war, dass die Lipide zusammen mit den Apolipoproteinen in die Dottergranula der Eizellen eingelagert wurden und nicht direkt in die Lipidtropfen. Auch bei den Elaeocyten wurden die Lipide nicht direkt in den Lipidtropfen eingelagert. Intakte Lipoproteine konnten per Dichtegradienten-Ultrazentrifugation nur aus Spermatogonien isoliert werden. Die isolierten Lipoproteine hatten die gleiche ‚Morphologie’ wie die aus der Coelomflüssigkeit isolierten, zeigten jedoch sehr viele Peptidfragmente im SDS-Gel, was auf eine beginnende Degradation hinweist. Es wird ein Modell für den Lipidtransport in Nereis virens vorgeschlagen, bei dem den Elaeocyten eine entscheidende Rolle im Lipidstoffwechsel zufällt.

Das neue digitale ‚Shakespeare-Bildarchiv Oppel-Hammerschmidt‘ an der Universitätsbibliothek Mainz : Reden und Beiträge anlässlich seiner öffentlichen Vorstellung am 17. November 2008 an der Johannes Gutenberg-Universität Mainz

On the basis of illustrations of Shakespeare's Hamlet, the new digital 'Oppel-Hammerschmidt Shakespeare Illustration Archive' at the Mainz University Library - together with a lavishly-constructed and multiply-linked Web interface version - was presented to the public on 17 November 2008. This e-book, edited by Andreas Anderhub and Hildegard Hammerschmidt-Hummel, contains the speeches and presentations given on the occasion of the opening ceremony of the electronic archive. The collection of the new archive, published here for the first time, holds about 3,500 images and is part of the only Shakespeare illustration archive in the world. The Shakespeare Illustration Archive was founded in 1946 by the internationally acclaimed Shakespeare and Goethe scholar, Prof. Horst Oppel. This part of the archive was donated to the Mainz University Library on condition that its holdings be digitalised and made available to the public. The collection has been named 'The Oppel-Hammerschmidt Shakespeare Illustration Archive' in accordance with the terms of the Agreement of Donation of 9, 15, and 16 September 2005, and honouring the 16 March 1988 Delegation of Authority and Declaration of Intent by Frau Ingeborg Oppel, Prof. Oppel's widow and legal assignee. Vice-President Prof. Jürgen Oldenstein opened the proceedings by noting that 2008 had been a good year for international Shakespeare scholarship. For, in London, the site of the 'Theatre' in Shoreditch, where Shakespeare's company performed, had been unearthed, and in Mainz the Shakespeare Archive had gone online with thousands of illustrations. The Dean of the Faculty of Philosophy and Philology, Prof. Mechthild Dreyer, who mentioned that she herself had long been successfully employing interdisciplinary research methods, took particular pleasure in the transdisciplinary approach to research resolutely pursued by Prof. Hammerschmidt-Hummel. Prof. Clemens Zintzen (Cologne), former President of the Mainz Academy of Literature and Sciences, recalled highlights from the more than sixty-year-long history of the Shakespeare Illustration Archive. Prof. Kurt Otten (Heidelberg and Cambridge) drew an impressive portrait of Horst Oppel's personality as an academic and praised his influential books on Goethe and Shakespeare. He pointed out that Oppel's Shakespeare Illustration Archive, the basis for many a dissertation, had enjoyed great popularity around the world. Prof. Otten also delineated the academic career of Prof. Hammerschmidt-Hummel and her new findings regarding Shakespeare's time, life and work. Prof. Rüdiger Ahrens OBE (Würzburg) drew attention to Prof. Hammerschmidt-Hummel's research results, directly or indirectly arising out of her work on the Shakespeare Illustration Archive. This research had centred on proving the authenticity of four visual representations of Shakespeare (the Chandos and Flower portraits, the Davenant bust and the Darmstadt Shakespeare death mask); solving the mystery around Shakespeare's 'Dark Lady'; and establishing the dramatist's Catholic religion. Prof. Hammerschmidt-Hummel reported on her 'Shakespeare Illustration' project, describing the nature, dimensions and significance of the Archive's pictorial material, which relates to all of Shakespeare's plays and stretches over five centuries. She explained that the digital 'Oppel-Hammerschmidt Illustration Archive' was an addition to the three-volume edition she had compiled, authored and edited for publication in 2003. Unlike the print version, however, the digital collection had only been partly editorially prepared. It represented source material and a basis for further work. Hammerschmidt-Hummel expressed her thanks to the Head of the Central University Library, Dr Andreas Anderhub, for his untiring commitment. After the initial donation had been made, he had entered enthusiastically into setting up the necessary contacts, getting all the work underway, and clearing the legal hurdles. Hammerschmidt-Hummel was especially grateful to University of Mainz librarian Heike Geisel, who had worked for nearly five years to carry out the large-scale digitalization of a total of 8,800 items. Frau Geisel was also extremely resourceful in devising ways of making the collection yield even more, e.g. by classifying and cross-linking the data, assembling clusters of individual topics that lend themselves to research, and (in collaboration with the art historian Dr Klaus Weber) making the archive's index of artists compatible with the data-bank of artists held by the University of Mainz Institute of Art History. In addition, she compiled an extremely helpful 'users' guide' to the new digital collection. Frau Geisel had enjoyed invaluable support from Dr Annette Holzapfel-Pschorn, the leading academic in the Central IT Department at the University, who set up an intelligent, most impressive Web interface using the latest application technologies. Frau Geisel and Dr Holzapfel-Pschorn were highly praised for their convincing demonstration, using illustrations to Hamlet, of how to access this well-devised and exceptionally user-friendly Web version. For legal reasons, Prof. Hammerschmidt-Hummel pointed out, the collection could not be released for open access on the internet. The media - as Dr Anderhub stressed in his foreword - had shown great interest in the new digital collection of thousands of Shakespearean illustrations (cf. Benjamin Cor's TV feature in "Tagesthemen", 17 November 2008, presented by Tom Buhrow). The ‘Oppel-Hammerschmidt Shakespeare Illustration Archive’ should also meet with particular interest not only among academic specialists, but also among the performers of the arts and persons active in the cultural realm in general, as well as theatre and film directors, literary managers, teachers, and countless Shakespeare enthusiasts.

Unione Europea e sanità

La tesi di dottorato "Unione Europea e Sanità" è uno studio sistematico del diritto alla salute e della protezione della sanità pubblica nell'ordinamento giuridico dell'Unione Europea. Il primo capitolo analizza le competenze sanitarie dell'Unione Europea, introdotte per la prima volta dal Trattato di Maastricht e definitivamente sistemate all'art. 168 TFUE. La norma identifica alcuni settori specifici nei quali l'Unione può agire e altri, quali l'organizzazione dei sistemi sanitari e la fornitura di cure mediche, che rimangono in capo agli Stati membri. Il secondo capitolo esamina le deroghe e le esigenze imperative connesse alla salvaguardia della salute nel mercato interno ed è suddiviso in tre sezioni dedicate alla libera circolazione delle merci, al diritto di stabilimento e alla libera prestazione dei servizi. Nella prima ci si è occupati dello sviluppo della legislazione farmaceutica. Nella seconda si sono analizzati il mutuo riconoscimento delle qualifiche professionali e le legislazioni statali che restringono il diritto di stabilimento degli operatori sanitari transfrontalieri. Nella terza si è rivolta l'attenzione alla mobilità dei pazienti che, attraverso la giurisprudenza della Corte di Giustizia, è stata trasfusa in un atto di diritto derivato. Il terzo capitolo si concentra sul ruolo del diritto alla salute nell'ordinamento giuridico dell'Unione Europea in considerazione del valore vincolante della Carta dei diritti fondamentali. Coerentemente, si è scelto di mantenere una struttura tripartita. Nella prima sezione, ci si interroga sull'esistenza di tale diritto alla luce dei pochi casi presenti. Nella seconda, lo si analizza per il tramite delle obbligazioni di proteggere, rispettare ed adempiere, enucleate attraverso alcuni strumenti internazionali e si verifica il ruolo del principio di non discriminazione in relazione all'accesso alle cure. Nella terza, infine, si verifica il ruolo del consenso informato rispetto alla sperimentazione clinica ed alla donazione di materiale biologico.
