An efficient Escherichia coli expression system for the production of a functional N-terminal domain of the T1R3 taste receptor.
2012
http://www.landesbioscience.com/; International audience; Sweet taste is mediated by a dimeric receptor composed of two distinct subunits, T1R2 and T1R3, whereas the T1R1/T1R3 receptor is involved in umami taste perception. The T1R1, T1R2, and T1R3 subunits are members of the small family of class C G protein-coupled receptors (GPCRs). The members of this family are characterized by a large N-terminal domain (NTD), which is structurally similar to bacterial periplasmic-binding proteins and contains the primary ligand-binding site. In a recent study, we described a strategy to produce a functional dimeric human T1R3-NTD. Although the protein was expressed as inclusion bodies (IBs) using the …

Cáncer hereditario: Importancia y necesidad de su detección
2013
A pesar de que tan solo el 1% de los casos de cáncer se pueden considerar de tipo hereditario, en la actualidad se han descrito más de 200 síndromes caracterizados por la agregación familiar de distintos tipos de tumores. La identificación a lo largo del siglo XX de muchos de los genes responsables de estos síndromes ha permitido un gran avance en el manejo de estas familias, a la hora de identificar o descartar los individuos a riesgo y establecer unas medidas preventivas específicas. Sin embargo, existe todavía un alto porcentaje de los casos hereditarios en los que la causa de la susceptibilidad es desconocida, siendo la búsqueda de nuevos genes mediante las nuevas tecnologías una de la…
The effect of peracetic acid on microbial community, water quality, nitrification and rainbow trout (Oncorhynchus mykiss) performance in recirculatin…
2020
Microbial biofilters control water quality and enable the overall function of recirculation aquaculture systems (RAS). Changes in environmental conditions can affect the abundance and interactions of the diverse microbial populations of the biofilter, affecting nitrification of harmful ammonium and thus fish health. Here, we examined the effect of different application frequencies (0, 1, 2 and 4 times per week) of a common disinfectant, peracetic acid (PAA, applied 1.1 mg l−1 twice per day), on biofilter microbial communities, focusing especially on nitrifying microbial groups and using a high throughput sequencing of 16S rRNA gene and quantitative PCR (qPCR). In addition, we measured biofi…
Correlación radiopatológica del tamaño tumoral en el cáncer de mama. Implicaciones terapéuticas
2022
Antecedentes: Las técnicas de imagen utilizadas en el cáncer de mama para determinar inicialmente el tamaño tumoral (T) son la mamografía y la ecografía, aceptándose como valor T inicial el mayor tamaño tumoral determinado por las dos técnicas. Tras la estimación del tamaño mediante técnicas convencionales, se realiza la biopsia de la lesión y a continuación se completa la estadificación con resonancia magnética (RM) en las pacientes indicadas. En la actualidad, la RM mamaria tiene indicaciones limitadas. Ante el aumento de indicación de la RM prequirúrgica, diferentes estudios han evaluado el impacto de sus hallazgos sobre el manejo de las pacientes y apoyan su mayor precisión frente a las…
Dialogicality in teaching process drama : three narratives, three frameworks
2018
This case study explores dialogicality in teaching process drama through the narratives and practices of three experienced drama teachers of the Open University. Dialogue is understood here in the context of ‘I-Thou’ attitude and as the phenomenon of heteroglossia. The analyses of the videotaped reflective interviews with the teachers and process dramas revealed a polyphonic picture of dialogicality in the teaching process, in which juxtapositions of communion and alterity are favoured. These findings may help drama teachers to become more conscious about the challenges and possibilities of generating a fluid and energised dialogicality in process drama. peerReviewed
Direct Measurement of Mammographic X-Ray Spectra with a Digital CdTe Detection System
2012
In this work we present a detection system, based on a CdTe detector and an innovative digital pulse processing (DPP) system, for high-rate X-ray spectroscopy in mammography (1–30 keV). The DPP system performs a height and shape analysis of the detector pulses, sampled and digitized by a 14-bit, 100 MHz ADC. We show the results of the characterization of the detection system both at low and high photon counting rates by using monoenergetic X-ray sources and a nonclinical X-ray tube. The detection system exhibits excellent performance up to 830 kcps with an energy resolution of 4.5% FWHM at 22.1 keV. Direct measurements of clinical molybdenum X-ray spectra were carried out by using a pinhole…

Opozycja wewnątrzpartyjna w Socjaldemokrtaycznej Partii Niemiec w latach 1980-1982
2016
At the beginning of the 1980s a very serious internal conflict within the Social Democratic Party of Germany (SPD) appeared, which was played out on a few levels. The first one w as the personal level, the second one was the program and ideology level. Both levels, especially in 1981 and in 1982 started to penetrate the strengthening the conflict and the signs of intra - party breakup, and revealing the views and actions of SPD party members, being in open opposition to the official policy of the social liberal government and the social democratic chancellor. Having entered opposition, the party adjusted the party program from above to the expectations of its members and its electorat e, ta…
