QCD resummation effects in forward $J/\psi$ and very backward jet inclusive production at the LHC
2017
We propose and study the inclusive production of a forward $J/\psi$ and a very backward jet at the LHC as an observable to reveal high-energy resummation effects \`a la BFKL. Our different predictions are based on the various existing mechanisms to describe the production of the $J/\psi$, namely, NRQCD singlet and octet contributions, and the color evaporation model.
Role of epdr1 and the znf518b factor in the development of colorectal cancer
2019
La principal causa de muerte por cáncer colorrectal (CCR), uno de los más comunes, es la metástasis. Así, encontrar marcadores de invasividad del tumor constituye un desafío importante. En este trabajo se muestra, primero con un array comercial de cDNA de CRC, que la expresión de ZNF518B y EPDR1 y de sus dos isoformas principales de ayuste, aumenta significativamente en los tumores. Después, con muestras pareadas de una cohorte prospectiva de 101 pacientes del Hospital Clínico de Valencia (HCV), se observó que la expresión de ambos genes está elevada en el tumor. EPDR1 codifica una proteína relacionada con las ependiminas, implicadas en contactos intercelulares y ZNF518B, codifica un putati…
Biedermeierowskie świadectwo zarazy - "Granit" Adalberta Stiftera
2021
The following article is an introduction to the Adalbert Stifter’s short story entitled Granite in Polish translation. The article explains the political and cultural origin of the work, its poetical form, its ethical and philosophical meaning. The Granite, included in the short story collection (Colorful Stones, 1853) is considered to be an important declaration of Biedermeier movement in Austria, its aesthetic as well as its ethic tradition, manifest of which was so-called „Gentle Law” (das sanfte Gesetz), i.e. an ordered existence harmony and an unspectacular, daily practising the humanism in the personal, country and social life. In Stifter’s piece it concerns also an extraordinary case…
Urban Services to Ecosystems: An Introduction
2021
Green infrastructure is a structural system of naturally developed human societies, capable of preserving and ensuring as much space as possible to the local biodiversity. For this reason, green infrastructure shall be planned and designed so that the urban built environment is in harmony with the surrounding biotic communities. The challenge is to sustain nature-based solutions in order to improve citizens’ awareness towards natural and semi-natural ecosystems while providing our society with a more liveable, healthier, safer and fairer environment. This book puts an emphasis on the services the city can offer to nature, thanks to a multidisciplinary approach involving scientists and pract…
Microstructure and characteristic properties of dogfish skin gelatin gels prepared by freeze/spray-drying methods
2020
International audience; The effects of two pretreatments (microwaves or oven-drying) on the dogfish (Squalus acanthias) skin as well as two drying processes (freeze-drying or spray-drying) on the extracted gelatins were studied. Thus six types of gelatins were obtained, three of which were freeze-dried (FG) and the others were spray-dried (SG), from the untreated skin (US), microwaves-pretreated skin (MS) and oven-pretreated skin (OS). The highest yield (8.67%) was obtained for the OSFG, while the lowest one (3.06%) was measured for the OSSG. Interestingly, all gelatins exhibited relatively high protein (84.02-89.53%), and low lipid (0.50-1.71%) and ash (3.05-7.17%) contents. In addition, g…
Involvement of an Alkane Hydroxylase System of Gordonia sp. Strain SoCg in Degradation of Solid n-Alkanes▿
2010
ABSTRACT Enzymes involved in oxidation of long-chain n -alkanes are still not well known, especially those in Gram-positive bacteria. This work describes the alkane degradation system of the n -alkane degrader actinobacterium Gordonia sp. strain SoCg, which is able to grow on n -alkanes from dodecane (C 12 ) to hexatriacontane (C 36 ) as the sole C source. SoCg harbors in its chromosome a single alk locus carrying six open reading frames (ORFs), which shows 78 to 79% identity with the alkane hydroxylase (AH)-encoding systems of other alkane-degrading actinobacteria. Quantitative reverse transcription-PCR showed that the genes encoding AlkB (alkane 1-monooxygenase), RubA3 (rubredoxin), RubA4…
Transfers of small analytes in a multiphasic stirred fruit yoghurt model
2007
International audience; The transfer of small analytes in a multiphasic stirred fruit yoghurt model, made of a pectin gel aimed to mimic fruit pieces and of a dairy gel done with milk acidified by glucono-δ-lactone hydrolysis, have been studied. The concentration gradients between the pectin gel and the dairy gel were the driving force for the migration of small analytes (i.e. water, protons and colorants). Water migrated from the dairy to the pectin gel, causing modifications in the water content of both gels and an equilibration of their water activity at 0.938±0.003. Inversely, protons migrated from the pectin to the dairy gel. These changes in composition of both gels being likely to ha…
Agar-based phantoms for skin diagnostic imaging
2020
Agar-based skin phantoms with different thicknesses and hemoglobin concentration were evaluated for diagnostics of skin lesions by RGB imaging. Scattering properties of the phantoms were simulated using intralipid, absorption properties – using lyophilized powder of human hemoglobin. RGB images of phantoms were captured by self-developed laboratory made devices. The algorithm for calculation of chromophore concentrations are based on Beer-Lambert law and includes the photon path length evaluated from the measured photon-time-of-flight signals. Optical properties and chromophore concentration maps of phantoms obtained from RGB images were analyzed. The influence of chromophore concentration …
La proteína C-reactiva y la procalcitonina como marcadores precoces de la fuga anastomótica en cirugía colorrectal
2019
Introducción La fuga anastomótica (FA) sigue siendo la complicación más temida después de la resección colorrectal con una incidencia descrita del 2-16% y una tasa de mortalidad del 12-30%. El diagnóstico precoz es fundamental para disminuir sus consecuencias clínicas. Hasta ahora se han propuesto muchos biomarcadores y algunos de ellos se han implementado en protocolos clínicos. Sin embargo, su precisión y utilidad aún se debaten. El objetivo de este estudio es determinar la fiabilidad de la proteína C reactiva (PCR), procalcitonina y neutrófilos en la detección precoz de la FA después de la cirugía colorrectal. Diseño estudio: Estudio prospectivo, observacional y multicéntrico (34 centros…
