description: A simple and environmentally friendly surfactant-assisted microextraction method combined with high-performance liquid chromatography fluorescence detection was developed for the determination of six fluoroquinolones in chicken livers. In the method, the analytes were transported into the hydrophobic extraction by ionic and nonionic surfactants. Three different surfactants were studied for this purpose, cationic Methyltrioctyl ammonium chloride (Aliquat 336), anionic sodium dodecyl sulfate (SDS), and nonionic trioctyl phosphine oxide (TOPO). Under optimum conditions, the limits of detection (LODs) and limits of quantification (LOQs) obtained using anionic surfactant ranged from 5 to 23 µg kg-1 and 15 to 78 µg kg-1 respectively. The LODs obtained from using cationic surfactant ranged from 9 to 21 µg kg-1 while the LOQs ranged from 31 to 71 µg kg-1. The LODs obtained from the method using nonionic surfactant ranged from 9 to 20 µg kg-1 and the LOQs ranged from 29 to 67 µg kg-1. Surfactant assisted-dispersive liquid liquid microextraction using SDS and Aliquat 336 were statistically compared and no significant statistical difference was observed between the two methods. The results obtained in this study indicate that the proposed method is cost-effective and environmentally friendly for the extraction and determination of fluoroquinolones in solid biological samples.

description: A flow-through biosensor has been developed and manufactured by 3D printing from poly(lactic acid). Uricase or tyrosinase were immobilized on the inner walls of the reactor cell and the concentrations of the reaction products, i.e., hydrogen peroxide in the case of uricase and quinone product of the tyrosine oxidation in the case of tyrosinase, were monitored in the amperometric mode. The screen-printed electrode modified with carbon black, pillar[5]arene and electropolymerized thionine and methylene blue was separated from the enzyme layer by 0.1 mm gap and used as a biosensor transducer. The components of the modifier layer exerted a synergetic effect and increased the cathodic current up to seven times compared to electrodes modified with individual components, increasing the sensitivity of the analysis. In the optimal conditions, biosensor allowed the determination of 1 × 10−7 to 1 × 10−5 M uric acid and 2 × 10−7 to 1 × 10−5 M tyrosine. The biosensors analyzed spiked samples of blood serum and urine and provided recoveries from 95 to 110%. Easy mounting of the flow-through cell and low cost of the replaceable parts make promising future application of the biosensor for routine clinical assays.

Where are you? A heideggerian analysis of the mobile phone
Creators: name: Ilharco, Fernando
Publisher: name: Comunicação & Cultura
Year: 2007

description: This paper is an attempt at clarifying the essential contours of the phenomenon that grounds the developments in contemporary mobile communication: the mobile phone. In so doing our investigation intends to answer the question of what a mobile phone is as such. The paper presents a description of the mobile phone and its contextualisation within some of the works of Martin Heidegger (1889-1976), seeking to uncover the essential mode in which a mobile phone is what it is. Grounding our analysis on the ontology of Heidegger’s Being and Time (Heidegger 1962), we claim that the mobile phone will only show itself as what it is in its being in-the-world where mobile phones are what they are. This analysis is complemented by an exploration of the relevance of another of Heidegger’s notions, that of Ge-stell (Heidegger 1977) as the essence of modern technology, for the understanding of human involvement with mobile phones. Against this ontological background, our analysis points out being-with, bringing together and timing as the essential contours of the mobile phone, all of these suggesting the deeper notions of actual situation and of disembodiment.

description: Exfoliation and preparation of large interlayer spacing and reactive graphene oxide (GO) powder are of crucial importance and neck technologies for their applications in polymer composites. Herein, we reported an innovative approach to prepare a large interlayer spacing reactive NCO-GO powder by covalent functionalization of GO with 4,4’-diphenylmethane diisocyanate (MDI). The morphology, microstructure, interlayer spacing, dispersion, and thermal stability of the NCO-GO powder were seriously investigated by FT-IR, XPS, XRD, TEM, TG, and Raman. Interlayer spacing of NCO-GO nanosheets was successfully expanded from 0.83 nm to 2.43 nm after modification, the NCO-GO powder showed better dispersion stability than GO in polar solvents and higher decomposition temperature. The fabricated novel NCO-GO powder showed a great prospect in the future to prepare graphene-based PU composites with significantly enhanced electrical conductivity and mechanical properties of PU elastomer. A novel and scalable method for preparing graphene oxide powder with large interlayer spacing and high reactivity is provided, which provides good application prospects for graphene composite polymer materials.

description: The present study is the first effort to a comprehensive evaluation of antityrosinase activity and chemometric analysis of Bauhinia vahlii. The experimental results revealed that the methanol extract of Bauhinia vahlii (BVM) possesses higher polyphenolic compounds and total antioxidant activity than those reported elsewhere for other more conventionally and geographically different varieties. The BVM contain saturated fatty acids such as hexadecanoic acid (10.15%), octadecanoic acid (1.97%), oleic acid (0.61%) and cis-vaccenic acid (2.43%) along with vitamin E (12.71%), α-amyrin (9.84%), methyl salicylate (2.39%) and β-sitosterol (17.35%), which were mainly responsible for antioxidant as well as tyrosinase inhibitory activity. Tyrosinase inhibitory activity of this extract was comparable to that of Kojic acid. These findings suggested that the B. vahlii leaves could be exploited as potential source of natural antioxidant and tyrosinase inhibitory agent, as well.

description: Thallium (Tl) can be released as a byproduct of smelting, mining, and other industries, causing human exposure. There are knowledge gaps on the toxicity of thallium compounds, so the National Toxicology Program is investigating the toxicity of thallium (I) sulfate in rodents. We developed and validated a method to quantitate Tl in rodent plasma and secondary matrices. Primary matrix standards and validation samples were digested with nitric acid and analyzed for Tl by inductively-coupled plasma – mass spectrometry (ICP-MS). Method performance was validated for linearity, accuracy, precision, and other criteria. Calibration was linear from 1.25 to 500 ng Tl/mL plasma; accuracy (RE) was −5.9 to 2.6% for all calibration standards. The lower limit of quantitation (LLOQ) was 1.25 ng Tl/mL plasma, and the limit of detection was 0.0370 ng Tl/mL plasma. Intra- and interday RE and precision (RSD) were −5.6 to −1.7% and ≤0.8% (intraday) and −4.8 to −1.3% and ≤4.3% (interday), respectively, at three sample concentration levels. Standards up to 10.0 x 103 ng/mL could be analyzed by dilution with digested blank matrix, with −6.4% RE and 5.4% RSD. Method was also evaluated in post-natal day 4 (PND4) Hsd:Sprague Dawley SD (HSD) dam and pup plasma, gestation day 18 (GD 18) HSD rat fetal homogenate, HSD rat urine, female HSD rat brain homogenate, female B6C3F1 mouse plasma. Background Tl was detected in control fetal and brain homogenates and urine at < 30% of LLOQ response. Results demonstrate that the method is suitable for determination of Tl in rodent matrices for toxicology studies.

description: It is a common practice to analyze AIDS longitudinal data using nonlinear mixed-effects (NLME) models with normal distribution for HIV dynamics. Normality of model errors may unrealistically obscure important features of subject variations. To partially explain between- and within-subject variations, covariates are usually introduced in such models; some covariates, however, may be often measured with substantial errors. This article, motivated by an AIDS clinical study, discusses a Bayesian NLME joint modeling approach to viral dynamic models with skew-t distribution in the presence of covariate measurement error. In this model, we fully integrate viral load response, time-varying CD4 covariate with measurement error, and time-dependent drug efficacy, which is a function of multiple treatment factors, into the data analysis. Thus, the purpose of this article is to demonstrate our models and methods with application to an AIDS clinical trial study. The results suggest that modeling HIV dynamics and virologic responses with consideration of covariate measurement error and time-varying clinical factors may be important for HIV/AIDS studies in providing quantitative guidance to better understand the virologic responses to antiretroviral treatment and to help evaluation of clinical trial design in existing therapies.

description: Os modos de pensar e agir sobre a produção e transmissão da informação e do saber, historicamente ligados ao mundo do impresso, alteram-se com a informação a ser gerada e a circular cada vez mais em canais electrónicos, complexificando as relações entre processos de desenvolvimento tecnológico e práticas e instituições sociais e culturais. Das mesmas Tecnologias de Informação e Comunicação (TIC) que potenciam o desenvolvimento emergem novas desigualdades, por dificuldades várias na interacção com as tecnologias e, assim, no acesso a conteúdos e serviços de informação. Designadas como «fractura digital», tais desigualdades são em geral vistas de forma redutora, mais focada nas infra-estruturas, nos equipamentos ou na largura de banda, do que nas motivações, nas novas competências ou nos diferentes padrões sociais de uso do acesso. Estes são aspectos cruciais que confrontam a literacia tradicional com novas e mais complexas questões.

description: A hydrophobic deep eutectic solvent (DES) based vortex-assisted liquid-liquid microextraction (LLME) procedure was developed for the effective and rapid determination of thiophanate-methyl (TM) and carbendazim (CA) in lake water and tap water samples, with an excellence extraction efficiency (recovery: 87.2% to 97.4%, enrichment factor: 87.2 to 97.4). Twelve hydrophobic DESs based on terpenoids and fatty acids/alcohols were prepared, and those with the highest recovery for TM and CA were selected. The main parameters, including assisting methods, molar ratio of DES components, volume of DES, and NaCl content that may affect vortex-assisted LLME, were optimized. The intra-day and inter-day relative standard deviation (RSD) of this method were from 1.7% to 3.8% and 1.8% to 4.1%, showing excellent precision. The proposed method exhibited suitable limits of detection (TM: 0.053 µg/mL; CA: 0.007 µg/mL) and limits of quantification (TM: 0.177 µg/mL; CA: 0.024 µg/mL).

description: To identify the most active antimicrobial fraction of Folium Syringae, four common pathogens were used in an in vitro screening. The results indicated that the combination of the 30% and 60% ethanol fraction (FSC) obtained from the water extraction was the most active fraction with a minimal inhibitory concentration of 0.65 mg mL− 1. FSC was also found to be able to protect mice from a lethal infection of Staphylococcus aureus at clinical dosage (0.2 g kg− 1) with a survival rate of 83.3%. The antibacterial activity of FSC was then tested using the serum pharmacology method which revealed that FSC exhibits a more long-lasting activity than the positive control (levofloxacin hydrochloride). The main components were confirmed to be iridoid glycosides and flavones by HPLC–MS analysis.

description: O artigo discute os grandes ideais do jornalismo americano, articulando-os na dependência de formantes socioculturais particulares à realidade dos EUA. Traça a sua evolução desde a proximidade indiferenciada com o poder político, ao afastamento radical, chegando ao modelo actual, que se pauta por uma articulação cívica. Conclui-se que o modelo americano não pode ser implantado em nenhum outro sistema. Surgiu de uma história única e foi moldado por uma relação com instituições políticas distintas e uma cultura política única, podendo, contudo, servir como inspiração democrática ideal.

Sobre a economia da cultura

Publisher: name: Comunicação & Cultura

description: A expressão «economia da cultura» revela uma noção funcional da cultura associada a determinadas actividades económicas relacionadas com a criatividade e os seus respectivos produtos. As indústrias culturais podem definir-se como as actividades que permitem produzir, distribuir e colocar no mercado bens e serviços culturais. Nos últimos anos, assistiu-se à democratização e à industrialização da cultura, questionando-se, no entanto, se isto significa uma melhoria da qualidade de vida ou, pelo contrário, a diminuição do nível qualitativo das manifestações culturais. A questão do papel da cultura e das políticas culturais levanta a questão da sustentabilidade dos mercados de bens culturais. De acordo com a teoria clássica de Baumol e Bowen, o crescimento da produtividade permanece limitado, ou quase impossível, na produção de espectáculos (v.g. ópera, teatro). Assim se coloca a questão do papel do Estado, que, para além da responsabilidade que lhe cabe na defesa do património, surge como indispensável na sustentação de determinado tipo de espectáculos ou de indústrias (v.g. cinema) sem dimensão competitiva.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Portugal padece há, pelo menos, 150 anos de um défice estrutural em matéria de educação e de qualificações. Esse desequilíbrio face aos demais parceiros europeus resulta de um desinvestimento sistemático no capital humano dos portugueses verificado até há cerca de 30 anos. O artigo começa por evidenciar a importância estratégica da opção de investir duradouramente na superação deste atraso e na reversão deste “ciclo longo” de atávica desqualificação da maioria da população, evidenciando como noutros países foi possível realizar a “revolução educativa”. Defende-se, de seguida, a evolução para um novo paradigma de educação como serviço – de proximidade – e o abandono de um modelo fabril – industrial – de formação. A iniciativa Novas Oportunidades representa também uma grande oportunidade para reorganizar a oferta inclusiva de educação-formação segundo padrões mais flexíveis e próximos das verdadeiras necessidades da procura. Por último, elabora-se sobre a missão da educação naquilo que ela encerra de redescoberta do imenso tesouro que habita o “interior” de Portugal e a alma de cada português. Afinal, a educação visa tornar as pessoas mais felizes e ajudá-las a descobrir o tesouro que reside na profundidade do sentido da vida.

description: Wave energy devices are novel structures in the marine environment and, as such, provide a unique habitat for biofouling organisms. In this study, destructive scrape samples and photoquadrats were used to characterise the temperate epibenthic community present on prototypes of the Pelamis wave energy converter. The biofouling observed was extensive and diverse with 115 taxa recorded including four non-native species. Vertical zonation was identified on the sides of the device, with an algae-dominated shallow subtidal area and a deeper area characterised by a high proportion of suspension-feeding invertebrates. Differences in species composition and biomass were also observed between devices, along the length of the device and between sampling dates. This research provides an insight into the variation of biofouling assemblages on a wave energy device as well as the potential technical and ecological implications associated with biofouling on marine renewable energy structures.

description: The effect of different dilution series on the obtained concentration uncertainty was investigated in order to identify the optimal dilution sequence which produces the smallest confidence interval on the sought concentration. A theoretical model was developed to describe this uncertainty, and a simple rule was obtained which was used to further reduce the inherent uncertainty caused by dilution procedures. The experimental analytical technique used to validate the theoretical model was total reflection x-ray fluorescence (TXRF) due to its simplicity and its simultaneous multielemental evaluations. To carry out the study two steps were made (1) model the theoretical uncertainties in the final concentration after a given dilution sequence through the developed mathematical formulation and (2) validate the results predicted by the obtained formulation by performing numerical evaluations on TXRF experimental spectra. Two sets of ad hoc samples were generated according to two different dilution series in order to experimentally assess the influence of the dilution sequences on the measured concentration uncertainties. In order to avoid systematic errors, the procedures and measurements were repeated in three independent laboratories. The proposed method identifies the optimal dilution sequence that minimizes the computed uncertainty of the final concentration which is particularly useful in techniques with high sensitivity (10−7 g/g or less). Since the formulation allows to reduce the inherent uncertainty component of the dilution procedure, our conclusions provide useful guidance for dilution procedures, regardless of the analytical technique used and the analytes.

description: Background and Objective: Tattoo ink stock products often contain potential carcinogens, which on large-scale population exposure may be clinically relevant. The aim of this autopsy study in mice was to screen major organs for clinical and subclinical cancers. Methods: Mice were tattooed on their backs. In total, 48 mice were included and divided into 4 groups; 11 mice tattooed black, 10 tattooed red, and 5 mice serving as untreated controls. A group of 22 mice with black tattoos and exposed to ultraviolet radiation (UVR) were also studied. The black and red inks were both stock products banned on the Danish market due to the measured contents of potential carcinogens; benzo(a)pyrene and 2-anisidine, respectively. The mice were housed for 1 year after tattooing, and autopsy study on internal organs was performed. Tissue samples were systematically taken from major organs for screening of subclinical changes, not detected by visual examination. Any observed deviation from normal structure was subject to biopsy and light microscopy. Results: All mice survived the 1-year observation period. Autopsy revealed no macroscopic signs of cancer. Microscopic search of internal organs showed no subclinical or clinical cancer. Conclusion: Despite extensive tattoos with 2 banned inks, the long-term observation in mice showed no internal cancers nor was the combination of carcinogen and UVR associated with cancer. Lack of observed malignancy might be explained by the fact that tattooing is only a single dose exposure. Registered data on carcinogens relies on repeated or chronic exposures. The study does not support the hypothesis that tattooing causes cancer.

description: Exfoliation and preparation of large interlayer spacing and reactive graphene oxide (GO) powder are of crucial importance and neck technologies for their applications in polymer composites. Herein, we reported an innovative approach to prepare a large interlayer spacing reactive NCO-GO powder by covalent functionalization of GO with 4,4’-diphenylmethane diisocyanate (MDI). The morphology, microstructure, interlayer spacing, dispersion, and thermal stability of the NCO-GO powder were seriously investigated by FT-IR, XPS, XRD, TEM, TG, and Raman. Interlayer spacing of NCO-GO nanosheets was successfully expanded from 0.83 nm to 2.43 nm after modification, the NCO-GO powder showed better dispersion stability than GO in polar solvents and higher decomposition temperature. The fabricated novel NCO-GO powder showed a great prospect in the future to prepare graphene-based PU composites with significantly enhanced electrical conductivity and mechanical properties of PU elastomer. A novel and scalable method for preparing graphene oxide powder with large interlayer spacing and high reactivity is provided, which provides good application prospects for graphene composite polymer materials.

description: During the past decade, many reforms were proposed and implemented for improving primary care in the US. This study assessed improvements in quality of primary care, using a nationally representative database. We conducted a retrospective trend analysis of National Inpatient Sample data (2007-2016). The quality of primary care was assessed using Prevention Quality Indicators (PQIs), which consist of 13 sets of preventable hospitalization conditions. PQI hospitalization decreased from 154,565 to 151,168 per million hospitalizations during the study period (relative decrease, 2.2%; P = 0.041). Age-adjusted hospitalization rate increased for diabetes short-term complications (relative increase, 46.9%; P < 0.001) and lower-extremity amputations (relative increase, 15.1%; P = 0.035). Age stratified trends showed that hospitalization rates decreased significantly in all age-groups for diabetes short-term complications. For lower-extremity amputations, hospitalization rates increased significantly in younger age groups and decreased significantly in the older age groups. All other PQIs showed either decreasing or no change in trends. Adults aged 18-64 years should be the focus for future prevention attempts for diabetes complications. Identifying and acting on the factors responsible for these changes could help in reversing the concerning trends observed in this study. Existing strategies should focus on improving access to diabetes care and self-management.

description: Background Itch sensitization has been reported in patients with chronic allergic skin diseases and observed in a mouse model of allergic contact dermatitis (ACD). There is evidence suggesting that neuroimmune interactions may contribute to itch sensitization, as an increase in dendritic cells (DCs) within ganglia has been observed during allergic conditions. However, how DCs interact with sensory neurons in ganglia during allergic conditions is still not known. This study aims to investigate the role of DCs in dorsal root ganglion (DRG) under ACD conditions, specifically focusing on itch sensitization within the DRG. The tolylene-2,4-diisocyanate (TDI) mouse model for ACD and the co-culture model of DCs and DRG neurons was employed in this study. Results We successfully induced ACD by TDI, as evidenced by the development of edema, elevated total serum IgE levels, and an observed itch reaction in TDI-sensitized mice. Calcium imaging and RT-qPCR analysis revealed that TDI-sensitized mice exhibited signs of peripheral sensitization, including a higher percentage of neurons responding to pruritogens and increased activation and expression of itch receptors in excised DRG of TDI-sensitized mice. Immunofluorescence and flow cytometric analysis displayed an increase of MHCII+ cells, which serves as a marker for DCs, within DRG during ACD. The co-culture study revealed that when DRG neurons were cultured with DCs, there was an increase in the number of neurons responsive to pruritogens and activation of itch receptors such as TRPA1, TRPV1, H1R, and TRPV4. In addition, the immunofluorescence and RT-qPCR study confirmed an upregulation of TRPV4. Conclusions Our findings indicate that there is an increase of MHCII+ cells and itch peripheral sensitization in DRG under TDI-induced ACD condition. It has been found that MHCII+ cells in DRG might contribute to the itch peripheral sensitization by activating itch receptors, as shown through co-culture studies between DRG neurons and DCs. Further studies are required to identify the specific mediator(s) responsible for peripheral sensitization induced by activated DCs.

description: Osteosarcoma (OS) is the most common type of primary malignant bone tumor. The high-throughput sequencing technology has shown potential abilities to illuminate the pathogenic genes in OS. This study was designed to find a powerful gene signature that can predict clinical outcomes. We selected OS cases with gene expression and survival data in the TARGET-OS dataset and GSE21257 datasets as training cohort and validation cohort, respectively. The univariate Cox regression and Kaplan-Meier analysis were conducted to determine potential prognostic genes from the training cohort. These potential prognostic genes underwent a LASSO regression, which then generated a gene signature. The harvested signature's predictive ability was further examined by the Kaplan-Meier analysis, Cox analysis, and receiver operating characteristic (ROC curve). More importantly, we listed similar studies in the most recent year and compared theirs with ours. Finally, we performed functional annotation, immune relevant signature correlation identification, and immune infiltrating analysis to better study he functional mechanism of the signature and the immune cells' roles in the gene signature's prognosis ability. A seventeen-gene signature (UBE2L3, PLD3, SLC45A4, CLTC, CTNNBIP1, FBXL5, MKL2, SELPLG, C3orf14, WDR53, ZFP90, UHRF2, ARX, CORT, DDX26B, MYC, and SLC16A3) was generated from the LASSO regression. The signature was then confirmed having strong and stable prognostic capacity in all studied cohorts by several statistical methods. We revealed the superiority of our signature after comparing it to our predecessors, and the GO and KEGG annotations uncovered the specifically mechanism of action related to the gene signature. Six immune signatures, including PRF1, CD8A, HAVCR2, LAG3, CD274, and GZMA were identified associating with our signature. The immune-infiltrating analysis recognized the vital roles of T cells CD8 and Mast cells activated, which potentially support the seventeen-gene signature's prognosis ability. We identified a robust seventeen-gene signature that can accurately predict OS prognosis. We identified potential immunotherapy targets to the gene signature. The T cells CD8 and Mast cells activated were identified linked with the seventeen-gene signature predictive power.
