Early stage primary bone lymphoma : a retrospective, multicenter rare cancer network (RCN) study

IntroductionLe lymphome primaire de l'os (LPO) représente moins de 1% de tous les lymphomes malins. Dans cette étude, nous avons évalué le profil de la maladie, les résultats thérapeutiques, et les facteurs pronostiques d'une série consécutive de patients atteints de LPO de stade I et II. Matériel et méthodeDans treize institutions du Réseau des Cancers Rares (Rare Cancer Network), 116 patients ont été traités pour un LPO entre 1987 et 2008, et sont l'objet de cette étude rétrospective. Quatre-vingt-sept patients ont subi une chimioradiothérapie (CXRT) sans (78), ou avec (9) une chirurgie, 15 ont bénéficié de radiothérapie (RT) sans (13), ou avec (2) chirurgie, 14 d'une chimiothérapie (CXT) sans (9), ou avec (5) chirurgie. La dose médiane de RT était de 40 Gy (4-60). Le nombre médian de cycles de CXT était de 6 (2-8). Le suivi médian était de 41 mois (6-242). RésultatsLe taux de réponse global à la fin du traitement était de 91% (74% de réponses complètes et 17% de réponses partielles). Une récidive locale ou une progression ont été observées chez 12 (10%) patients et une récidive systémique chez 17 (15%) patients. La survie globale, la survie spécifique, et le contrôle local à 5 ans ont été de 76%, 78% et 92%, respectivement. En analyse univariée (log-rank test), les facteurs pronostiques favorables pour la survie globale et la survie spécifique étaient: un indice pronostique international (IPI) inférieur ou égale à 1 (P = 0.009), un grade histologique élevé (P = 0.04), une CXRT (P = 0.05), une CXT (P = 0.0004), une réponse complète (P <0.0001), et une dose de supérieure à 40 Gy (p = 0.005). Concernant le contrôle local, seules la rémission complète et stade I ont été des facteurs favorables. En analyse multivariée, le score IPI, la dose de RT, la rémission complète, et la CXT ont influencé le résultat de façon indépendante en ce qui concerne la survie globale et la survie spécifique. La rémission complète a été le seul facteur prédictif pour le contrôle local. ConclusionCette étude multicentrique rétrospective confirme le bon pronostic du LPO de stade précoce traité par une combinaison de chimio-radiothérapie. Une dose de suffisant de radiothérapie et un nombre adéquat de cycles de chimiothérapie ont été suivis des résultats les plus favorables.

Development and evaluation of neural network models to estimate daily solar radiation at Córdoba, Argentina

The objective of this work was to develop neural network models of backpropagation type to estimate solar radiation based on extraterrestrial radiation data, daily temperature range, precipitation, cloudiness and relative sunshine duration. Data from Córdoba, Argentina, were used for development and validation. The behaviour and adjustment between values observed and estimates obtained by neural networks for different combinations of input were assessed. These estimations showed root mean square error between 3.15 and 3.88 MJ m-2 d-1 . The latter corresponds to the model that calculates radiation using only precipitation and daily temperature range. In all models, results show good adjustment to seasonal solar radiation. These results allow inferring the adequate performance and pertinence of this methodology to estimate complex phenomena, such as solar radiation.

Family history of cancer and the risk of cancer: a network of case-control studies.

BACKGROUND: The risk of many cancers is higher in subjects with a family history (FH) of cancer at a concordant site. However, few studies investigated FH of cancer at discordant sites. PATIENTS AND METHODS: This study is based on a network of Italian and Swiss case-control studies on 13 cancer sites conducted between 1991 and 2009, and including more than 12 000 cases and 11 000 controls. We collected information on history of any cancer in first degree relatives, and age at diagnosis. Odds ratios (ORs) for FH were calculated by multiple logistic regression models, adjusted for major confounding factors. RESULTS: All sites showed an excess risk in relation to FH of cancer at the same site. Increased risks were also found for oral and pharyngeal cancer and FH of laryngeal cancer (OR = 3.3), esophageal cancer and FH of oral and pharyngeal cancer (OR = 4.1), breast cancer and FH of colorectal cancer (OR = 1.5) and of hemolymphopoietic cancers (OR = 1.7), ovarian cancer and FH of breast cancer (OR = 2.3), and prostate cancer and FH of bladder cancer (OR = 3.4). For most cancer sites, the association with FH was stronger when the proband was affected at age <60 years. CONCLUSIONS: Our results point to several potential cancer syndromes that appear among close relatives and may indicate the presence of genetic factors influencing multiple cancer sites.

Differences of Functional Connectivity Brain Network in Emotional Judgment

Using combined emotional stimuli, combining photos of faces and recording of voices, we investigated the neural dynamics of emotional judgment using scalp EEG recordings. Stimuli could be either combioned in a congruent, or a non-congruent way.. As many evidences show the major role of alpha in emotional processing, the alpha band was subjected to be analyzed. Analysis was performed by computing the synchronization of the EEGs and the conditions congruent vs. non-congruent were compared using statistical tools. The obtained results demonstrate that scalp EEG ccould be used as a tool to investigate the neural dynamics of emotional valence and discriminate various emotions (angry, happy and neutral stimuli).

Sistema de community cloud aplicat a la preservació digital personal (personal archiving) PYRAMID

La preservació digital (PD) s'ha convertit en un problema persistent per a tots els que vulguin conservar la seva informació digital, garantir el seu estat i consultar aquest informació en el transcurs del temps. Fins ara només grans institucions amb coneixement expert i eines especialitzades han pogut fer front a aquest problema, però la preservació digital no pot ser abordada per una sola institució o nació. Les biblioteques, arxius i altres institucions de conservació de la memòria comparteixen aquest repte de la mateixa manera que els col•leccionistes i creadors, que ho fan a títol individual.L’objectiu del projecte és crear l'aplicació Pyramid que està concebuda com una eina de suport orientada a l'usuari domèstic (sense coneixements tècnics ni de preservació) per a la preservació a mig i llarg termini de col•leccions digitals, texts i vídeos, tal que funcioni com un antivirus (en BackGround) i preservi la informació sense requerir un cost addicional a l'ordinador i que l'usuari no noti cap molèstia a l'hora de fer les seves tasques diàries

Use of active personal dosemeters in interventional radiology and cardiology: Tests in laboratory conditions and recommendations - ORAMED project

Active personal dosemeters (APD) have been found to be very efficient tools to reduce occupational doses in many applications of ionizing radiation. In order to be used in interventional radiology and cardiology (IR/IC), APDs should be able to measure low energy photons and pulsed radiation with relatively high instantaneous personal dose equivalent rates. A study concerning the optimization of the use of APDs in IR/IC was performed in the framework of the ORAMED project, a Collaborative Project (2008-2011) supported by the European Commission within its 7th Framework Program. In particular, eight commercial APDs were tested in continuous and pulsed X-ray fields delivered by calibration laboratories in order to evaluate their performances. Most of APDs provide a response in pulsed mode more or less affected by the personal dose equivalent rate, which means they could be used in routine monitoring provided that correction factors are introduced. These results emphasize the importance of adding tests in pulsed mode in type-test procedures for APDs. Some general recommendations are proposed in the end of this paper for the selection and use of APDs at IR/IC workplaces.

Leverage and beliefs: Personal experience and risk taking in margin lending

What determines risk-bearing capacity and the amount of leverage in financial markets? Thispaper uses unique micro-data on collateralized lending contracts during a period of financialdistress to address this question. An investor syndicate speculating in English stocks wentbankrupt in 1772. Using hand-collected information from Dutch notarial archives, we examinechanges in lenders' behavior following exposure to potential (but not actual) losses. Before thedistress episode, financiers that lent to the ill-fated syndicate were indistinguishable from therest. Afterwards, they behaved differently: they lent with much higher haircuts. Only lendersexposed to the failed syndicate altered their behavior. The differential change is remarkable sincethe distress was public knowledge, and because none of the lenders suffered actual losses ? allfinanciers were repaid in full. Interest rates were also unaffected; the market balanced solelythrough changes in collateral requirements. Our findings are consistent with a heterogeneousbeliefs-interpretation of leverage. They also suggest that individual experience can modify thelevel of leverage in a market quickly.

Functional expression of PHO1 to the Golgi and trans-Golgi network and its role in export of inorganic phosphate.

Arabidopsis thaliana PHO1 is primarily expressed in the root vascular cylinder and is involved in the transfer of inorganic phosphate (Pi) from roots to shoots. To analyze the role of PHO1 in transport of Pi, we have generated transgenic plants expressing PHO1 in ectopic A. thaliana tissues using an estradiol-inducible promoter. Leaves treated with estradiol showed strong PHO1 expression, leading to detectable accumulation of PHO1 protein. Estradiol-mediated induction of PHO1 in leaves from soil-grown plants, in leaves and roots of plants grown in liquid culture, or in leaf mesophyll protoplasts, was all accompanied by the specific release of Pi to the extracellular medium as early as 2-3 h after addition of estradiol. Net Pi export triggered by PHO1 induction was enhanced by high extracellular Pi and weakly inhibited by the proton-ionophore carbonyl cyanide m-chlorophenylhydrazone. Expression of a PHO1-GFP construct complementing the pho1 mutant revealed GFP expression in punctate structures in the pericycle cells but no fluorescence at the plasma membrane. When expressed in onion epidermal cells or in tobacco mesophyll cells, PHO1-GFP was associated with similar punctate structures that co-localized with the Golgi/trans-Golgi network and uncharacterized vesicles. However, PHO1-GFP could be partially relocated to the plasma membrane in leaves infiltrated with a high-phosphate solution. Together, these results show that PHO1 can trigger Pi export in ectopic plant cells, strongly indicating that PHO1 is itself a Pi exporter. Interestingly, PHO1-mediated Pi export was associated with its localization to the Golgi and trans-Golgi networks, revealing a role for these organelles in Pi transport.

Writing for the contemporany naturalistic stage: a personal process of creation

El objetivo principal de este proyecto es desarrollar más a fondo y consolidar los objetivos formativos y competencias del grado en Estudios Ingleses a través de un trabajo de escritura creativa, en concreto, la creación de una obra teatral original.

Programa de atención a pacientes con Esclerosis Lateral Amiotrófica (ELA): Información para el personal sanitario de los Centros de Atención Primaria

Etimológicamente, esclerosis significa endurecimiento (skerós es "endurecmiento patológico" y osis, "enfermedad") y hace referencia al estado de la médula espinal en las fases avanzadas de la enfermedad. Lateral significa "al lado" y pone de manifiesto la ubicación del daño en la médula espinal. Por último, el término amiotrófica significa "sin nutrición muscular" y se refiere a la pérdida de señales que los nervios envían normalmente a los músculos. La Esclerosis Lateral Amiotrófica (ELA) es la enfermedad más grave de un grupo de dolencias que tienen síntomas similares y son conocidas como "enfermedades de motoneuronas": la Atrofia Muscular Juvenil o Enfermedad de Kugelberg Welander, la Atrofia Muscular Infantil o Enfermedad de Werdnig Hoffmann, la parálisis bulbar progresiva, la amiotrofia focal benigna, la esclerosis lateral primaria y la atrofia muscular espinobulbar o Enfermedad de Kennedy.
