Protezione dei dati personali e tutela della sicurezza pubblica: la prospettiva europea sul caso Apple vs FBI e la strage di San Bernardino

L’obiettivo di questa trattazione è quello di esporre il rapporto controverso fra il diritto alla privacy, garantito ad ogni cittadino, e la tutela della sicurezza nazionale. L’episodio protagonista che verrà analizzato riguarda il contenzioso che, nel dicembre del 2015, ha coinvolto la società Apple Inc. e l’Fbi. Nella prima parte dell’elaborato l’attenzione verrà focalizzata sul concetto di privacy, approfondendo la sua diversa impostazione nelle normative americana e europea. In particolare, si partirà dal right to be let alone del 1890 per giungere a quella che è la concezione attuale del diritto alla protezione dei dati personali secondo il GDPR e il Privacy Act per poi elaborarne un confronto. Successivamente, verrà analizzato il tema della tutela della sicurezza pubblica facendo ricorso ad alcuni esempi di leggi emanate a seguito degli attentati terroristici dell’11 settembre. Nella seconda parte, dunque, si entrerà nel vivo della Strage di San Bernardino, ripercorrendo passo dopo passo le indagini. Il focus sarà lo scontro legale tra Apple e Fbi e le trattative in merito al dispositivo rinvenuto durante la strage. Infine, si ipotizzerà di “trasportare” il caso nella normativa europea, ossia immaginando la sua risoluzione qualora la normativa adottata non fosse stata quella americana.

Melhoria da Atenção à Saúde da Pessoa Idosa na ESF Manoel Bernardino dos Santos, Torres/RS

TORRES, Yiliana Maria Castillo. Melhoria da Atenção à Saúde da Pessoa Idosa na ESF Manoel Bernardino dos Santos, Torres, RS. 2015. 112f. Trabalho de Conclusão de Curso (Curso de Especialização em Saúde da Família) - Departamento de Medicina Social, Faculdade de Medicina, Universidade Federal de Pelotas, Pelotas, 2015. O presente volume trata da intervenção realizada na Estratégia de Saúde da Família (ESF) Manoel Bernardino dos Santos com o foco na melhoria da atenção à saúde da pessoa Idosa. O cuidado com os idosos é fundamental na atenção básica, haja vista a fragilização da saúde que ocorre nesta fase da vida, o aumento da incidência de doenças crônicas e degenerativas, com aumento de risco de morbimortalidade, sendo importante o bom acompanhamento da saúde da pessoa idosa para que lhe seja proporcionado uma melhor qualidade de vida. A intervenção foi precedida de uma análise da situação de saúde da população, na qual foi definida o foco de intervenção. A área de abrangência da ESF é composta por 290 usuários idosos. O cadastro foi realizado de acordo com as informações obtidas na ficha de acompanhamento de hipertensos, diabéticos, ou alguma outra doença crônica que apresente os usuários maiores de 60 anos. Utilizamos o protocolo do Ministério da Saúde de Idosos para ser um referencial para as ações executadas. A intervenção apresentou bons resultados em um período de três meses de realização e, apesar de não alcançarmos a meta prevista de 80% da cobertura, foi possível cadastrar 140 usuários idosos (48,3%). Ao final da intervenção todas as metas de qualidade foram atingidas em 100% em todos os indicadores. É importante apontar os cadastrados no Programa passaram a ter um melhor acolhimento, um atendimento de qualidade com exame físico completo, avaliação nutricional, pedidos de exames complementares de acordo ao protocolo para identificar a gravidade das suas doenças e até outras doenças associadas. Todos receberam receitas de medicamentos da Farmácia Popular. Foram também avaliados quanto à necessidade de atendimento odontológico. Os usuários que estavam com atraso nas consultas foram visitados pelos ACS para que assistissem à consulta. A nossa intervenção melhorou o engajamento público entre a comunidade, gestores e profissionais da saúde, os usuários adquiriram muitos conhecimentos sobre estas doenças, além disso, foi muito importante para o serviço, pois o trabalho ficou mais organizado, oferecendo uma atenção de qualidade aos usuários incluindo a saúde bucal. Também foi muito relevante para a equipe, porque com ela fizemos várias capacitações sobre a atenção às pessoas com hipertensão arterial sistêmica e diabetes mellitus, doenças frequentes nos usuários maiores de 60 anos na atenção primária à saúde. Palavras-chave: atenção primária à saúde; saúde da família; saúde do idoso; assistência domiciliar; saúde bucal

Systematic review and cladistic analysis of the Hernandariinae (Opiliones: Gonyleptidae)

The harvestmen subfamily Hernandariinae is reviewed and a new classification is proposed based on cladistic analysis using 67 morphological characters. The subfamily is composed of six genera and 23 species and occurs in south-southeastern Brazil, Paraguay, and northeastern Argentina. Fourteen new combinations are proposed: Hernandaria armatifrons (Roewer, 1917); H. una (Mello-Leitão, 1927); Acrogonyleptes granulatus (H. Soares, 1966); A. pectinifemur (Soares & Soares, 1947); Acanthogonyleptes alticola (Mello-Leitão, 1922); A. editus (Roewer, 1943); A. fallax (Mello-Leitão, 1932); A. fulvigranulatus (Mello-Leitão, 1922); A. marmoratus (Mello-Leitão, 1940); A. pictus (Piza, 1942); A. singularis (Mello-Leitão, 1935); A. soaresi (Mello-Leitão, 1944); A. variolosus (Mello-Leitão, 1944). Seven synonymies are proposed: Proweyhia Mello-Leitão, 1927 and Metaxundarava Mello-Leitão, 1927 = Hernandaria Sørensen, 1884; Apembolephaenus calcaratus Soares & Soares, 1945 = H. armatifrons (Roewer, 1917); Sphaerobunus Rower, 1917 and Paraproweyhia Soares & Soares, 1947 = Acrogonyleptes Roewer, 1917; Paraproweyhia curitibae Soares & Soares, 1947 = Acrogonyleptes exochus (Mello-Leitão, 1931); and Melloleitaniana curitibae B. Soares, 1943 = Acrogonyleptes spinifrons Roewer, 1917. Three species are revalidated: Acrogonyleptes granulatus (H. Soares, 1966), A. pectinifemur (Soares & Soares, 1947), and A. spinifrons Roewer, 1917. Seven new species are described: Hernandaria sundermannorum sp. nov. (São Paulo State, Brazil), Hernandaria anitagaribaldiae sp. nov. (Santa Catarina State, Brazil), Hernandaria zumbii sp. nov. (Santa Catarina State, Brazil), Hernandaria chicomendesi sp. nov. (Santa Catarina State, Brazil), Acrogonyleptes cheguevarai sp. nov. (Rio Grande do Sul State, Brazil), Pseudotrogulus pagu sp. nov. (São Paulo State, Brazil), Pseudotrogulus trotskyi sp. nov.

As relações entre construção da imagem corporal, função paterna e hiperatividade: reflexões a partir da Pesquisa IRDI

A partir da psicanálise, 31 indicadores clínicos de risco para o desenvolvimento infantil (IRDI) foram construídos e aplicados em 727 crianças entre 0 e 18 meses. Uma subamostra de 280 crianças foi avaliada com a idade de três anos. Uma primeira análise de resultados mostra uma relação entre imagem do corpo, dificuldade de separação, agitação motora e vínculos corporais estreitos com as mães. Esses resultados são discutidos criticamente à luz da noção atual de hiperatividade.

Promoção da saúde e a formação cidadã: a percepção do professor sobre cidadania

Vários movimentos internacionais, como o da Promoção da Saúde, têm colocado o exercício da cidadania como estratégia de melhoria das condições de vida e saúde da população de países em desenvolvimento. A educação tem papel importante no desenvolvimento deste exercício, merecendo atenção especial a escola e o professor, por estar mais próximo do aluno. Assim, o objetivo deste estudo foi conhecer as representações sociais do professor sobre cidadania, sobre o aluno ser cidadão, além de sua visão sobre o seu papel e o da escola no desenvolvimento dela. Foram entrevistados quarenta professores de escola pública da cidade de São Paulo, e seus discursos foram analisados pela metodologia do Discurso do Sujeito Coletivo (DSC). A maioria dos professores considera a escola como um espaço onde a cidadania deve ser desenvolvida e com o professor tendo grande responsabilidade nesse desenvolvimento; sabe da importância de suas atitudes e ensino na formação do aluno; reconhece o aluno como um futuro cidadão e percebe a cidadania como uma participação ativa na sociedade, além dos direitos e deveres. Os professores revelaram algumas atitudes favoráveis ao desenvolvimento do exercício da cidadania, apontando para o alcance de melhores condições de saúde e vida da população brasileira.

Does Training Laparoscopic Skills in a Virtual Reality Simulator Improve Surgical Performance?

Background and Purpose: Several different methods of teaching laparoscopic skills have been advocated, with virtual reality surgical simulation (VRSS) being the most popular. Its effectiveness in improving surgical performance is not a consensus yet, however. The purpose of this study was to determine whether practicing surgical skills in a virtual reality simulator results in improved surgical performance. Materials and Methods: Fifteen medical students recruited for the study were divided into three groups. Group I (control) did not receive any VRSS training. For 10 weeks, group II trained basic laparoscopic skills (camera handling, cutting skill, peg transfer skill, and clipping skill) in a VRSS laparoscopic skills simulator. Group III practiced the same skills and, in addition, performed a simulated cholecystectomy. All students then performed a cholecystectomy in a swine model. Their performance was reviewed by two experienced surgeons. The following parameters were evaluated: Gallbladder pedicle dissection time, clipping time, time for cutting the pedicle, gallbladder removal time, total procedure time, and blood loss. Results: With practice, there was improvement in most of the evaluated parameters by each of the individuals. There were no statistical differences in any of evaluated parameters between those who did and did not undergo VRSS training, however. Conclusion: VRSS training is assumed to be an effective tool for learning and practicing laparoscopic skills. In this study, we could not demonstrate that VRSS training resulted in improved surgical performance. It may be useful, however, in familiarizing surgeons with laparoscopic surgery. More effective methods of teaching laparoscopic skills should be evaluated to help in improving surgical performance.

Phylogenetic position of the acariform mites: sensitivity to homology assessment under total evidence

Background: Mites (Acari) have traditionally been treated as monophyletic, albeit composed of two major lineages: Acariformes and Parasitiformes. Yet recent studies based on morphology, molecular data, or combinations thereof, have increasingly drawn their monophyly into question. Furthermore, the usually basal (molecular) position of one or both mite lineages among the chelicerates is in conflict to their morphology, and to the widely accepted view that mites are close relatives of Ricinulei. Results: The phylogenetic position of the acariform mites is examined through employing SSU, partial LSU sequences, and morphology from 91 chelicerate extant terminals (forty Acariformes). In a static homology framework, molecular sequences were aligned using their secondary structure as guide, whereby regions of ambiguous alignment were discarded, and pre-aligned sequences analyzed under parsimony and different mixed models in a Bayesian inference. Parsimony and Bayesian analyses led to trees largely congruent concerning infraordinal, well-supported branches, but with low support for inter-ordinal relationships. An exception is Solifugae + Acariformes (P. P = 100%, J. = 0.91). In a dynamic homology framework, two analyses were run: a standard POY analysis and an analysis constrained by secondary structure. Both analyses led to largely congruent trees; supporting a (Palpigradi (Solifugae Acariformes)) clade and Ricinulei as sister group of Tetrapulmonata with the topology (Ricinulei (Amblypygi (Uropygi Araneae))). Combined analysis with two different morphological data matrices were run in order to evaluate the impact of constraining the analysis on the recovered topology when employing secondary structure as a guide for homology establishment. The constrained combined analysis yielded two topologies similar to the exclusively molecular analysis for both morphological matrices, except for the recovery of Pedipalpi instead of the (Uropygi Araneae) clade. The standard (direct optimization) POY analysis, however, led to the recovery of trees differing in the absence of the otherwise well-supported group Solifugae + Acariformes. Conclusions: Previous studies combining ribosomal sequences and morphology often recovered topologies similar to purely morphological analyses of Chelicerata. The apparent stability of certain clades not recovered here, like Haplocnemata and Acari, is regarded as a byproduct of the way the molecular homology was previously established using the instrumentalist approach implemented in POY. Constraining the analysis by a priori homology assessment is defended here as a way of maintaining the severity of the test when adding new data to the analysis. Although the strength of the method advocated here is keeping phylogenetic information from regions usually discarded in an exclusively static homology framework; it still has the inconvenience of being uninformative on the effect of alignment ambiguity on resampling methods of clade support estimation. Finally, putative morphological apomorphies of Solifugae + Acariformes are the reduction of the proximal cheliceral podomere, medial abutting of the leg coxae, loss of sperm nuclear membrane, and presence of differentiated germinative and secretory regions in the testis delivering their products into a common lumen.

Probing neutrino oscillations in supersymmetric models at the Large Hadron Collider

The lightest supersymmetric particle may decay with branching ratios that correlate with neutrino oscillation parameters. In this case the CERN Large Hadron Collider (LHC) has the potential to probe the atmospheric neutrino mixing angle with sensitivity competitive to its low-energy determination by underground experiments. Under realistic detection assumptions, we identify the necessary conditions for the experiments at CERN's LHC to probe the simplest scenario for neutrino masses induced by minimal supergravity with bilinear R parity violation.

Finding the Higgs boson through supersymmetry

The study of displaced vertices containing two b-jets may provide a double discovery at the Large Hadron Collider (LHC): we show how it may not only reveal evidence for supersymmetry, but also provide a way to uncover the Higgs boson necessary in the formulation of the electroweak theory in a large region of the parameter space. We quantify this explicitly using the simplest minimal supergravity model with bilinear breaking of R-parity, which accounts for the observed pattern of neutrino masses and mixings seen in neutrino oscillation experiments.

Dispersion of electron g-factor with optical transition energy in (In,Ga)As/GaAs self-assembled quantum dots

The electron spin precession about an external magnetic field was studied by Faraday rotation on an inhomogeneous ensemble of singly charged, self-assembled (In,Ga)As/GaAs quantum dots. From the data the dependence of electron g-factor on optical transition energy was derived. A comparison with literature reports shows that the electron g-factors are quite similar for quantum dots with very different geometrical parameters, and their change with transition energy is almost identical.

Heparin affects the interaction of kininogen on endothelial cells

In the plasma kallikrein-kinin system, it has been shown that when plasma prekallikrein (PM) and high molecular weight kininogen (HK) assemble on endothelial cells, plasma kallikrein (huPK) becomes available to cleave HK, releasing bradykinin, a potent mediator of the inflammatory response. Because the formation of soluble glycosaminoglycans occurs concomitantly during the inflammatory processes, the effect of these polysaccharides on the interaction of HK on the cell surface or extracellular matrix (ECM) of two endothelial cell lines (ECV304 and RAEC) was investigated. In the presence of Zn(+2), HK binding to the surface or ECM of RAEC was abolished by heparin; reduced by heparan sulfate, keratan sulfate, chondroitin 4-sulfate or dermatan sulfate; and not affected by chondroitin 6-sulfate. By contrast, only heparin reduced HK binding to the ECV304 cell surface or ECM. Using heparin-correlated molecules such as low molecular weight dextran sulfate, low molecular weight heparin and N-desulfated heparin, we suggest that these effects were mainly dependent on the charge density and on the N-sulfated glucosamine present in heparin. Surprisingly, PM binding to cell- or ECM-bound-HK and PM activation was not modified by heparin. However, the hydrolysis of HK by huPK, releasing BK in the fluid phase, was augmented by this glycosaminoglycan in the presence of Zn(2+). Thus, a functional dichotomy exists in which soluble glycosaminoglycans may possibly either increase or decrease the formation of BK. In conclusion, glycosaminoglycans that accumulated in inflammatory fluids or used as a therapeutic drug (e.g., heparin) could act as pro- or anti-inflammatory mediators depending on different factors within the cell environment.

The Penicillium chrysogenum aclA gene encodes a broad-substrate-specificity acyl-coenzyme A ligase involved in activation of adipic acid, a side-chain precursor for cephem antibiotics

Activation of the cephalosporin side-chain precursor to the corresponding CoA-thioester is an essential step for its incorporation into the P-lactam backbone. To identify an acyl-CoA ligase involved in activation of adipate, we searched in the genome database of Penicillium chrysogenum for putative structural genes encoding acyl-CoA ligases. Chemostat-based transcriptome analysis was used to identify the one presenting the highest expression level when cells were grown in the presence of adipate. Deletion of the gene renamed aclA, led to a 32% decreased specific rate of adipate consumption and a threefold reduction of adipoyl-6-aminopenicillanic acid levels, but did not affect penicillin V production. After overexpression in Escherichia coli, the purified protein was shown to have a broad substrate range including adipate. Finally, protein-fusion with cyan-fluorescent protein showed co-localization with microbody-borne acyl-transferase. Identification and functional characterization of aclA may aid in developing future metabolic engineering strategies for improving the production of different cephalosporins. (C) 2009 Elsevier Inc.

Functional characterization of the oxaloacetase encoding gene and elimination of oxalate formation in the beta-lactam producer Penicillium chrysogenum

Penicillium chrysogenum is widely used as an industrial antibiotic producer, in particular in the synthesis of g-lactam antibiotics such as penicillins and cephalosporins. In industrial processes, oxalic acid formation leads to reduced product yields. Moreover, precipitation of calcium oxalate complicates product recovery. We observed oxalate production in glucose-limited chemostat cultures of P. chrysogenum grown with or without addition of adipic acid, side-chain of the cephalosporin precursor adipoyl-6-aminopenicillinic acid (ad-6-APA). Oxalate accounted for up to 5% of the consumed carbon source. In filamentous fungi, oxaloacetate hydrolase (OAH; EC3.7.1.1) is generally responsible for oxalate production. The P. chrysogenum genome harbours four orthologs of the A. niger oahA gene. Chemostat-based transcriptome analyses revealed a significant correlation between extracellular oxalate titers and expression level of the genes Pc18g05100 and Pc22g24830. To assess their possible involvement in oxalate production, both genes were cloned in Saccharomyces cerevisiae, yeast that does not produce oxalate. Only the expression of Pc22g24830 led to production of oxalic acid in S. cerevisiae. Subsequent deletion of Pc22g28430 in P. chrysogenum led to complete elimination of oxalate production, whilst improving yields of the cephalosporin precursor ad-6-APA. (C) 2011 Elsevier Inc.

Evaluation of carcass characteristics of Bos indicus and tropically adapted Bos taurus breeds selected for postweaning weight

Data from 9 studies were compiled to evaluate the effects of 20 yr of selection for postweaning weight (PWW) on carcass characteristics and meat quality in experimental herds of control Nellore (NeC) and selected Nellore (NeS), Caracu (CaS), Guzerah (GuS), and Gir (GiS) breeds. These studies were conducted with animals from a genetic selection program at the Experimental Station of Sertaozinho, Sao Paulo State, Brazil. After the performance test (168 d postweaning), bulls (n = 490) from the calf crops born between 1992 and 2000 were finished and slaughtered to evaluate carcass traits and meat quality. Treatments were different across studies. A meta-analysis was conducted with a random coefficients model in which herd was considered a fixed effect and treatments within year and year were considered as random effects. Either calculated maturity degree or initial BW was used interchangeably as the covariate, and least squares means were used in the multiple-comparison analysis. The CaS and NeS had heavier (P = 0.002) carcasses than the NeC and GiS; GuS were intermediate. The CaS had the longest carcass (P < 0.001) and heaviest spare ribs (P < 0.001), striploin (P < 0.001), and beef plate (P = 0.013). Although the body, carcass, and quarter weights of NeS were similar to those of CaS, NeS had more edible meat in the leg region than did CaS bulls. Selection for PWW increased rib-eye area in Nellore bulls. Selected Caracu had the lowest (most favorable) shear force values compared with the NeS (P = 0.003), NeC (P = 0.005), GuS (P = 0.003), and GiS (P = 0.008). Selection for PWW increased body, carcass, and meat retail weights in the Nellore without altering dressing percentage and body fat percentage.

Requirement for PLC gamma 2 in IL-3 and GM-CSF-Stimulated MEK/ERK Phosphorylation in Murine and Human Hematopoietic Stem/Progenitor Cells

Even though the involvement of intracellular Ca(2+) (Ca(i)(2+)) in hematopoiesis has been previously demonstrated, the relationship between Ca(i)(2+) signaling and cytokine-induced intracellular pathways remains poorly understood. Herein, the molecular mechanisms integrating Ca(2+) signaling with the extracellular signal-regulated kinase 1/2 (ERK1/2) pathway in primary murine and human hematopoietic stem/progenitor cells stimulated by IL-3 and GM-CSF were studied. Our results demonstrated that IL-3 and GM-CSF stimulation induced increased inositol 1,4,5-trisphosphate (IP(3)) levels and Ca(i)(2+) release in murine and human hematopoietic stem/ progenitor cells. In addition, Ca(i)(2+) signaling inhibitors, such as inositol 1,4,5-trisphosphate receptor antagonist (2-APB), PKC inhibitor (GF109203), and CaMKII inhibitor (KN-62), blocked phosphorylation of MEK activated by IL-3 and GM-CSF, suggesting the participation of Ca(2+)-dependent kinases in MEK activation. In addition, we identify phospholipase C gamma 2 (PLC gamma 2) as a PLC gamma responsible for the induction of Ca(2+) release by IL-3 and GM-CSF in hematopoietic stem/progenitor cells. Furthermore, the PLCg inhibitor U73122 significantly reduced the numbers of granulocyte-macrophage colony-forming units after cytokine stimulation. Similar results were obtained in both murine and human hematopoietic stem/progenitor cells. Taken together, these data indicate a role for PLC gamma 2 and Ca(2+) signaling through the modulation of MEK in both murine and human hematopoietic stem/ progenitor cells. J. Cell.
