Uma festa de princesa para a Gata Borralheira

We analyze in this paper how the enunciator of two Brazilian magazines (Capricho and Atrevida) builds his enunciatee. Our analysis is based on French Semiotics and on woks by Eric Landowski (2002), whose studies about semiotization of social behavior point out the fact that the society excludes people who are not similar to those who belong to groups considered as a reference. In the textual construction, we noticed that the enunciator uses figures which allow us to visualize euphoric ways of life. However, we intend to verify if the figures show if these magazines are made for enunciatees from different social class or not. This verification is important as there is also a disphoric way of life, i.e., a segregated or excluded way of life.

Retratos da Espanha em Os fantasmas de Goya

1792, Madri. After years of inactivity, the Spanish Inquisition is born again with the mission of containing the laic winds that blow from the revolutionary France. Inês Bilbatúa, a rich merchant’s daugther, is victim of the inquisitorial machinery which tortures and violates her, through one of their abetters, the Dominican monk Lorenzo. Before being arrested, the young lady had served as model for the painter Francisco of Goya, who had also portrayed the monk Lorenzo. The Aragonese painter’s figure serves as narrative conductor of a history that narrates the young Inês’ via crucis and, at the same time, it recreates the historical scenery of the Napoleonic invasion (1808), through a basic element, the painting. Our work intends to analyze the relationships among movie, painting and history present in “Goya’s ghosts” (2006), of the Czech director Milos Forman (1932) - whose script was adapted to a homonymous book in 2007 -, a movie that is based on the artistic production of Francisco of Goya y Lucientes (1746 -1828), official painter of Carlos’ IV (1788 -1808) court and the most lucid columnist of his time, that knew how to capture in his works the religious fanaticism, the populist fervour, the governor’s hypocrisy and the horror and the violence of the war.

Phospho-mTOR in non-tumour and tumour bladder urothelium: Pattern of expression and impact on urothelial bladder cancer patients

Urothelial bladder carcinoma (UBC) is heterogeneous in its pathology and clinical behaviour. Evaluation of prognostic and predictive biomarkers is necessary, in order to produce personalised treatment options. The present study used immunohistochemistry to evaluate UBC sections containing tumour and non-tumour areas from 76 patients, for the detection of p-mTOR, CD31 and D2-40 (blood and lymphatic vessels identification, respectively). Of the non-tumour and tumour sections, 36 and 20% were scored positive for p-mTOR expression, respectively. Immunoexpression was observed in umbrella cells from non-tumour urothelium, in all cell layers from non-muscle-invasive (NMI) tumours (including expression in superficial cells), and in spots of cells from muscle-invasive (MI) tumours. Positive expression decreased from non-tumour to tumour urothelium, and from pTl/pTis to pT3/pT4 tumours; however, the few pT3/pT4 positive cases had worse survival rates, with 5-year disease-free survival being significantly lower. Angiogenesis occurrence was impaired in pT3/pT4 tumours that did not express p-mTOR. In conclusion, p-mTOR expression in non-tumour umbrella cells is likely a reflection of their metabolic plasticity, and extension to the inner layers of the urothelium in NMI tumours is consistent with an enhanced malignant potential. The expression in cell spots in a few MI tumours and absence of expression in the remaining tumours is intriguing and requires further research. Additional studies regarding the up- and downstream effectors of the mTOR pathway should be conducted.

O debate francês acerca da instrução pública e seus desdobramentos no Brasil

Este artigo tem por objetivo analisar aspectos históricos das questões políticas, ideológicas e conceituais que estiveram presentes nas discussões referentes à instrução nacional francesa no final do século XVIII, enfatizando as proposições de Condorcet, no Rapport de 1792, como sendo base desse tipo de debate durante o processo revolucionário na França. Privilegiamos, portanto, analisar as prerrogativas discursivas dessa proposta e o certame suscitado a partir dela, pois resultaram, até mesmo, em novas proposições, entre elas as de Romme, Robespierre, Lepelletier e Lakanal. Trata-se de uma abordagem que nos proporciona a compreensão da base moderna do debate sobre instrução pública que se configurou no século XIX. Essa concorrência de ideias entre os franceses se estabeleceu como o grande legado teórico para os sistemas modernos de ensino, inclusive o brasileiro. Depreendemos, ainda, que a instrução defendida na França estava permeada pelos ideais de razão, moral e cientificismo.

Relation of Uric Acid to Serum Levels of High-Sensitivity C-Reactive Protein, Triglycerides, and High-Density Lipoprotein Cholesterol and to Hepatic Steatosis

Increased uric acid (UA) is strongly linked to cardiovascular disease. However, the independent role of UA is still debated because it is associated with several cardiovascular risk factors including obesity and metabolic syndrome. This study assessed the association of UA with increased high-sensitivity C-reactive protein (hs-CRP), increased ratio of triglyceride to high-density lipoprotein cholesterol (TG/HDL), sonographically detected hepatic steatosis, and their clustering in the presence and absence of obesity and metabolic syndrome. We evaluated 3,518 employed subjects without clinical cardiovascular disease from November 2008 through July 2010. Prevalence of tis-CRP >= 3 mg/L was 19%, that of TG/HDL >= 3 was 44%, and that of hepatic steatosis was 43%. In multivariable logistic regression after adjusting for traditional cardiovascular risk factors and confounders, highest versus lowest UA quartile was associated with hs-CRP >= 3 mg/L (odds ratio [OR] 1.52, 95% confidence interval [CI] 1.01 to 2.28, p = 0.04), TG/HDL >= 3 (OR 3.29, 95% CI 2.36 to 4.60, p <0.001), and hepatic steatosis (OR 3.10, 95% CI 2.22 to 4.32, p <0.001) independently of obesity and metabolic syndrome. Association of UA with hs-CRP >= 3 mg/L became nonsignificant in analyses stratified by obesity. Ascending UA quartiles compared to the lowest UA quartile demonstrated a graded increase in the odds of having 2 or 3 of these risk conditions and a successive decrease in the odds of having none. In conclusion, high UA levels were associated with increased TG/HDL and hepatic steatosis independently of metabolic syndrome and obesity and with increased hs-CRP independently of metabolic syndrome.

Inter-rater reliability of the evaluation of muscular chains associated with posture alterations in scoliosis

Background: In the Global postural re-education (GPR) evaluation, posture alterations are associated with anterior or posterior muscular chain impairments. Our goal was to assess the reliability of the GPR muscular chain evaluation. Methods: Design: Inter-rater reliability study. Fifty physical therapists (PTs) and two experts trained in GPR assessed the standing posture from photographs of five youths with idiopathic scoliosis using a posture analysis grid with 23 posture indices (PI). The PTs and experts indicated the muscular chain associated with posture alterations. The PTs were also divided into three groups according to their experience in GPR. Experts' results (after consensus) were used to verify agreement between PTs and experts for muscular chain and posture assessments. We used Kappa coefficients (K) and the percentage of agreement (%A) to assess inter-rater reliability and intra-class coefficients (ICC) for determining agreement between PTs and experts. Results: For the muscular chain evaluation, reliability was moderate to substantial for 12 PI for the PTs (% A: 56 to 82; K: 0.42 to 0.76) and perfect for 19 PI for the experts. For posture assessment, reliability was moderate to substantial for 12 PI for the PTs (% A > 60%; K: 0.42 to 0.75) and moderate to perfect for 18 PI for the experts (% A: 80 to 100; K: 0.55 to 1.00). The agreement between PTs and experts was good for most muscular chain evaluations (18 PI; ICC: 0.82 to 0.99) and PI (19 PI; ICC: 0.78 to 1.00). Conclusions: The GPR muscular chain evaluation has good reliability for most posture indices. GPR evaluation should help guide physical therapists in targeting affected muscles for treatment of abnormal posture patterns.

On some species of Taeniotes Audinet-Serville, 1835 (Coleoptera: Cerambycidae: Lamiinae)

Taeniotes farinosus (Linnaeus, 1758) is a species that has been confused with other species during the past two centuries. In this work we demonstrate that Taeniotes farinosus sensu auctorum is not the species described by Linnaeus and designate a lectotype to establish its identity. Taeniotes pulverulentus (Olivier, 1790), currently synonymous with T. farinosus, is revalidated. Taeniotes guttullaris Schwarzer, 1929 and T parafarinosus Breuning, 1971 are junior synonyms of T. pulverulentus; Lamia subocellata Olivier, 1792 (= Taeniotes subocellatus) is a junior synonym of Cerambyx farinosus (= T farinosus). Additionally we monnei, a new species from Brazil and Argentina, is described and figured. Taeniotes peruanus provide annotated bibliographic references to T. farinosus and T pulverulentus. Taeniotes Breuning 1971 is figured for the first time.

Detection of the Epstein-Barr virus in blood and bone marrow mononuclear cells of patients with aggressive B-cell non-Hodgkin's lymphoma is not associated with prognosis

The Epstein-Barr virus (EBV) is associated with a large spectrum of lymphoproliferative diseases. Traditional methods of EBV detection include the immunohistochemical identification of viral proteins and DNA probes to the viral genome in tumoral tissue. The present study explored the detection of the EBV genome, using the BALF5 gene, in the bone marrow or blood mononuclear cells of patients with diffuse large B-cell lymphomas (DLBCL) and related its presence to the clinical variables and risk factors. The results show that EBV detection in 21.5% of patients is not associated with age, gender, staging, B symptoms, international prognostic index scores or any analytical parameters, including lactate dehydrogenase (LDH) or beta-2 microglobulin (B2M). The majority of patients were treated with R-CHOP-like (rituximab. cyclophosphamide, doxorubicin, vincristine and prednisolone or an equivalent combination) and some with CHOP-like chemotherapy. Response rates [complete response (CR) + partial response (PR)] were not significantly different between EBV-negative and -positive cases, with 93.2 and 88.9%, respectively. The survival rate was also similar in the two groups, with 5-year overall survival (OS) rates of 64.3 and 76.7%, respectively. However, when analyzing the treatment groups separately there was a trend in EBV-positive patients for a worse prognosis in patients treated with CHOP-like regimens that was not identified in patients treated with R-CHOP-like regimens. We conclude that EBV detection in the bone marrow and blood mononuclear cells of DLBC patients has the same frequency of EBV detection on tumoral lymphoma tissue but is not associated with the risk factors, response rate and survival in patients treated mainly with immunochemotherapy plus rituximab. These results also suggest that the addition of rituximab to chemotherapy improves the prognosis associated with EBV detection in DLBCL.

Characterization of PAR1 and FGFR1 expression in invasive breast carcinomas: Prognostic significance

Breast cancer is the most common cause of cancer mortality among women worldwide. Among the several factors associated with breast cancer development, angiogenesis plays an essential role and has currently emerged as a potential diagnostic, prognostic and therapeutic target. Protease-activated receptor 1 (PAR1) and fibroblast growth factor receptor 1 (FGFR1) have important activities in tumor angiogenesis and progression. The aim of this study was to investigate the prognostic significance of these two receptors, hypothesising significant correlations between receptor expression in tumor angiogenesis and clinicopathological parameters customarily used in breast cancer prognosis and prediction. Formalin-fixed and paraffin-embedded samples of ductal invasive breast carcinomas were used to analyze the expression of PAR1 and FGFR1, in the tumor cells as well as in the tumor stroma, and further determine intratumoral microvessel density (iMVD) to quantify intratumoral angiogenesis. Correlations between PAR1 and FGFR1 expression in tumor cells and stroma, iMVD and several clinicopathological parameters and molecular markers used in breast cancer diagnosis have been addressed. The correlation between PAR1 and FGFR1 suggests an association of the two receptors with a more aggressive breast cancer phenotype and, consequently, a potential role during tumor progression. The results reported in the present study also emphasize the importance of microenvironmental factors in tumor progression, while precluding the positive association between iMVD and breast cancer aggressiveness.

L-Carnitine induces recovery of liver lipid metabolism in cancer cachexia

Cancer cachexia causes metabolic alterations with a marked effect on hepatic lipid metabolism. l-Carnitine modulates lipid metabolism and its supplementation has been proposed as a therapeutic strategy in many diseases. In the present study, the effects of l-carnitine supplementation on gene expression and on liver lipid metabolism-related proteins was investigated in cachectic tumour-bearing rats. Wistar rats were assigned to receive 1 g/kg of l-carnitine or saline. After 14 days, supplemented and control animals were assigned to a control (N), control supplemented with l-carnitine (CN), tumour-bearing Walker 256 carcinosarcoma (TB) and tumour-bearing supplemented with l-carnitine (CTB) group. The mRNA expression of carnitine palmitoyltransferase I and II (CPT I and II), microsomal triglyceride transfer protein (MTP), liver fatty acid-binding protein (L-FABP), fatty acid translocase (FAT/CD36), peroxisome proliferator-activated receptor-alpha (PPAR-alpha) and organic cation transporter 2 (OCTN2) was assessed, and the maximal activity of CPT I and II in the liver measured, along with plasma and liver triacylglycerol content. The gene expression of MTP, and CPT I catalytic activity were reduced in TB, who also showed increased liver (150%) and plasma (3.3-fold) triacylglycerol content. l-Carnitine supplementation was able to restore these parameters back to control values (p < 0.05). These data show that l-carnitine preserves hepatic lipid metabolism in tumour-bearing animals, suggesting its supplementation to be of potential interest in cachexia.

Engorde de pulpo (Octopus vulgaris) alimentado exclusivamente con boga (Boops boops) de descarte de la acuicultura

[EN] The use of low value fish (Bogue, Boops boops), accidentally reared in seabream culture cages, as a sole food in octopus farming was tested in two different experiments located in Canary Islands. In a first experiment two different initial sizes were compared: 1,5 kg & 2,3 kg, both at a density of 11 kg/m3. Initial density was increased in a second experiments to 16 kg/m3 testing two lower initial weights: 1,0 kg & 0,8 kg. Bogue as a single feed was found to be good enough to sustain a good growth in octopus cage rearing. Best growth in terms of specific growth rate and average daily growth was obtained with the lowest grow size, 0,8 kg.

Effetto dell'erbicida Terbutilazina sulla crescita di flagellate marine in coltura

Il fitoplancton è costituito da organismi molto importanti per l'ambiente marino e molto diversificati sia dal punto di vista morfologico che fisiologico.Questi organismi sono normalmente soggetti ai cambiamenti stagionali e alle variazioni dell'ambiente dovute sia a fenomeni naturali che all'impatto antropico, sempre più rilevante. Con questa tesi si è voluto approfondire l'effetto di erbicidi comunemente usati dall'uomo in agricoltura su delle microalghe flagellate rappresentative del Mar Adriatico. L'inquinante scelto è la Terbutilazina, sostanza utilizzata per il diserbo del mais e diffusa in tutta l'area padano-venera, come dimostrano i dati dei campionamenti ARPA, che riportano la presenza di Terbutilazina e del suo prodotto di degradazione Desetil-Terbutilazina a concentrazioni superiori al limite fissato sia nelle acque superficiali che in quelle sotterranee. Anche in mare come riportato in letteratura (Carafa et. al 2009)è stato riscontrato a concentrazioni superiori al limite previsto dalla normativa vigente in Italia. In particolare il meccanismo d'azione di questo erbicida interferisce con la fotosintesi, agendo sulle proteine di membrana dei cloroplasti, rimpiazzando il chinone accettore di elettroni QB della proteina D1 del fotosistema II. Più specie di microalghe fatte crescere in colture 'batch' sono state testate a diverse concentrazioni di erbicida in condizione di luce nutrienti costanti. Questi esperimenti sono stati inoltre condotti a due diverse temperature (20 e 25°C) per studiare l'effetto di questo inquinante in correlazione con l'attuale aumento di temperatura in atto nel pianeta. In una prima fase di screening è stato valutato l'effetto della Terbutilazina su 9 specie di flagellate rappresentative dell'Adriatico, tramite misure dell'efficienza fotosintetica. Grazie a questa prima fase sono state individuate le microalghe e le relative concentrazioni di Terbutilazina da utilizzare negli esperimenti. Per gli esperimenti, sono state scelte le due specie algali Gonyaulax spinifera e Prorocentrum minimum sulle quali si è approfondito lo studio dell'effetto dell'inquinante alle due temperature, attraverso una serie di analisi volte ad individuare le risposte in termini di crescita e di fisiologia delle alghe quali: conteggio delle cellule, torbidità, efficienza fotosintetica, consumo di nutrienti, quantità di clorofilla e di polisaccaridi extracellulari prodotti. La scelta di queste microalghe è stata dettata dal fatto che Gonyaulax spinifera si è rivelata la microalga più sensibile a concentrazioni di erbicida più vicine a quelle ambientali fra tutte le alghe valutate, mentre Prorocentrum minimum è fra le dinoflagellate più frequenti e rappresentative del Mar Adriatico (Aubry et al. 2004), anche se non particolarmente sensibile; infatti P. minimum è stato testato ad una concentrazione di erbicida maggiore rispetto a quelle normalmente ritrovate in ambiente marino. Dai risultati riportati nella tesi si è visto come l'erbicida Terbutilazina sia in grado di influenzare la crescita e la fotosintesi di microalghe flagellate dell'Adriatico anche a concentrazioni pari a quelle rilevate in ambiente, e si è evidenziato che gli effetti sono maggiori alle temperature in cui le microalghe hanno una crescita meno efficiente. Questi studi hanno messo in evidenza anche l'utilità delle misure di fotosintesi tramite fluorimetro PAM nel valutare le risposte delle microalghe agli erbicidi triazinici. Inoltre la diversa risposta delle microalghe osservata, potrebbe avere conseguenze rilevanti sulle fioriture estive di fitoplancton in caso di presenza in mare di Terbutilazina, anche a concentrazioni non particolarmente elevate. Questo lavoro si inserisce in un contesto più ampio di ricerca volto alla modellizzazione della crescita algale in presenza di inquinanti ed in concomitanza con le variazioni di temperatura. Infatti i dati ottenuti insieme a misure di carbonio cellulare, non ancora effettuate, saranno utili per la messa a punto di nuove parametrizzazioni che si avvicinino maggiormente ai dati reali, per poi simulare i possibili scenari futuri variando le condizioni ambientali e le concentrazioni dell'inquinante studiato.
