Aproximaciones al estudio de la interacción individuo-paisaje a modo de evocacion comunicativa intrapersonal (2a. parte)

El análisis de la interacción individuo-paisaje presenta numerosas perspectivas de estudio vinculadas a la generación e interpretación de simbolismos e imaginarios. La capacidad significante y/o de evocación comunicativa del paisaje encuentra, en la comunicación intrapersonal, una argumentación relevante en el proceso de construcción de un aparato teórico que permita estudiar el proceso de apropiación y vivencia del paisaje en términos de manifestación comunicativa. El despliegue de un aparato teórico que permita interpretar el mensaje del paisaje así como descodificar su discurso intangible, representa el objetivo principal de la investigación que se presenta a continuación.

Manual de CATMARC, 2a edició: una primera lectura

Comentari crític a la segona edició del Manual del CATMARC. Es comenta la nova estructura adoptada i els criteris que sembla que s'han seguit. Si a la primera edició (1987) el format estava recolzat en l'Instltut Cátala de Bibliografía, la segona no presenta cap institució que l'avali. Al format originari s'afegeixen, sense aparent justificado, nous camps, alguns adaptáis d'USMARC. Camps d'ús local del SICAB que trenquen el caràcter de norma acceptadaque tenia CATMARC. El format d'autoritats modifica el d'USMARC, en el qual es basa. Un apéndix llista els canvis introduïts a la nova edició del format, tot indicant lurs fonts.

Front propagation in the A+B->2A reaction under subdiffusion

We consider an irreversible autocatalytic conversion reaction A+B->2A under subdiffusion described by continuous-time random walks. The reactants transformations take place independently of their motion and are described by constant rates. The analog of this reaction in the case of normal diffusion is described by the Fisher-Kolmogorov-Petrovskii-Piskunov equation leading to the existence of a nonzero minimal front propagation velocity, which is really attained by the front in its stable motion. We show that for subdiffusion, this minimal propagation velocity is zero, which suggests propagation failure.

Reticulocyte dynamic and hemoglobin variability in hemodialysis patients treated with Darbepoetin alfa and C.E.R.A.: a randomized controlled trial.

BACKGROUND: In a simulation based on a pharmacokinetic model we demonstrated that increasing the erythropoiesis stimulating agents (ESAs) half-life or shortening their administration interval decreases hemoglobin variability. The benefit of reducing the administration interval was however lessened by the variability induced by more frequent dosage adjustments. The purpose of this study was to analyze the reticulocyte and hemoglobin kinetics and variability under different ESAs and administration intervals in a collective of chronic hemodialysis patients. METHODS: The study was designed as an open-label, randomized, four-period cross-over investigation, including 30 patients under chronic hemodialysis at the regional hospital of Locarno (Switzerland) in February 2010 and lasting 2 years. Four subcutaneous treatment strategies (C.E.R.A. every 4 weeks Q4W and every 2 weeks Q2W, Darbepoetin alfa Q4W and Q2W) were compared with each other. The mean square successive difference of hemoglobin, reticulocyte count and ESAs dose was used to quantify variability. We distinguished a short- and a long-term variability based respectively on the weekly and monthly successive difference. RESULTS: No difference was found in the mean values of biological parameters (hemoglobin, reticulocytes, and ferritin) between the 4 strategies. ESAs type did not affect hemoglobin and reticulocyte variability, but C.E.R.A induced a more sustained reticulocytes response over time and increased the risk of hemoglobin overshooting (OR 2.7, p = 0.01). Shortening the administration interval lessened the amplitude of reticulocyte count fluctuations but resulted in more frequent ESAs dose adjustments and in amplified reticulocyte and hemoglobin variability. Q2W administration interval was however more favorable in terms of ESAs dose, allowing a 38% C.E.R.A. dose reduction, and no increase of Darbepoetin alfa. CONCLUSIONS: The reticulocyte dynamic was a more sensitive marker of time instability of the hemoglobin response under ESAs therapy. The ESAs administration interval had a greater impact on hemoglobin variability than the ESAs type. The more protracted reticulocyte response induced by C.E.R.A. could explain both, the observed higher risk of overshoot and the significant increase in efficacy when shortening its administration interval.Trial registrationClinicalTrials.gov NCT01666301.

Comportamiento de glicinina, beta-conglicinina y alfa-amilasa en semillas de soja deterioradas y no deterioradas

El objetivo del trabajo fue estudiar el comportamiento de glicinina y beta-conglicinina y la actividad de alfa-amilasa en semillas deterioradas y no deterioradas de 10 cultivares de soja [Glycine max (L.) Merr.]. Las semillas se sometieron a dos tratamientos: deterioradas por envejecimiento acelerado y no deterioradas. Se determinó la presencia de las proteínas de reserva a partir de semillas con 0, 3 y 8 días de germinadas por electroforesis en geles de poliacrilamida (SDS-PAGE). La actividad de la alfa-amilasa se determinó bioquímicamente en semillas con 0, 3, 8 y 12 días de germinadas. No hubo diferencias en la presencia de bandas de glicinina y beta-conglicinina en semillas no deterioradas hasta los 8 días de germinadas. Las semillas deterioradas se comportaron en forma similar a las no deterioradas. La actividad de la alfa-amilasa aumentó en semillas germinadas hasta 8 días y disminuyó a los 12 días. En semillas deterioradas la actividad enzimática disminuyó con respecto a las no deterioradas. El deterioro artificial no afectó la presencia de glicinina y beta-conglicinina pero alteró la actividad de la alfa-amilasa hasta los 12 días de germinación. Los cultivares estudiados mostraron comportamiento diferencial frente a la actividad de esta enzima.

Vitamin D deficiency and a CYP27B1-1260 promoter polymorphism are associated with chronic hepatitis C and poor response to interferon-alfa based therapy.

BACKGROUND & AIMS: Vitamin D is an important immune modulator and preliminary data indicated an association between vitamin D deficiency and sustained virologic response (SVR) rates in hepatitis C virus (HCV) genotype 1 patients. We, therefore, performed a comprehensive analysis on the impact of vitamin D serum levels and of genetic polymorphisms with functional relevance within the vitamin D cascade on chronic hepatitis C and its treatment. METHODS: Vitamin D serum levels, genetic polymorphisms within the vitamin D receptor and 1α-hydroxylase were determined in a cohort of 468 HCV genotype 1, 2, and 3 infected patients who were treated with interferon-alfa based regimens. RESULTS: Chronic hepatitis C was associated with a high incidence of severe vitamin D deficiency compared to controls (25(OH)D(3)<10 ng/ml in 25% versus 12%, p<0.00001). 25(OH)D(3) deficiency correlated with SVR in HCV genotype 2 and 3 patients (50% and 81% SVR for patients with and without severe vitamin D deficiency, respectively, p<0.0001). In addition, the CYP27B1-1260 promoter polymorphism rs10877012 had substantial impact on 1,25-dihydroxyvitamin D serum levels (72, 61, and 60 pmol/ml for rs10877012 AA, AC, and CC, respectively, p=0.04) and on SVR rates in HCV genotype 1, 2, and 3 infected patients (77% and 65% versus 42% for rs10877012 AA, AC, and CC, respectively, p=0.02). CONCLUSIONS: Chronic hepatitis C virus infection is associated with vitamin D deficiency. Reduced 25-hydroxyvitamin D levels and CYP27B1-1260 promoter polymorphism leading to reduced 1,25-dihydroxyvitamin D levels are associated with failure to achieve SVR in HCV genotype 1, 2, and 3 infected patients.
