Growing a population of Cynara cardunculus L. for further selection as a reference energy crop

A population of cultivated cardoon (Cynara cardunculus var. altilis DC) was grown in Madrid (Spain) as a reference crop to select outstanding individuals for energy applications. The work was carried out within the frame of the Spanish funded projects PROBIOCOM (INIA) and FP13-ENER. Seeds for this work were produced by one of the partners of PROBIOCOM - the Agro-Energy Group of UPM - and came from a clonal crop (in vitro propagated plants) previously grown in Madrid. IMIDRA, as Head of that Project, established the reference crop according to the protocol for cardoon energy crop and was responsible for the crop. Seeds were sown in seed trays and once the plants had true leaves they were transplanted into the field. Collection of field data involved 449 individuals at the rosette stage and the dataset comprised the measurement of plant height, rosette diameter and leaf length; leaf type was determined as well. Individuals exhibiting larger leaf size were selected and categorized into two categories: undivided-like leaf blade (16 individuals) and pinnately lobed leaf blade (12 individuals). For these individuals, leaf fresh weight, number of leaves and leaf length of previously selected leaves were determined. Furthermore, three measurements were performed with a SPAD chlorophyll meter and the Munsell color chart. Morphological features were taken according CPVO-OCVV and UPOV protocols. Most plants exhibited pinnately leaves which generally resulted in larger sizes than the undivided-like leaf plants. Results suggested that the morphological plant type could be used as a preliminary selection criterion of C. cardunculus for biomass production; however, further studies are needed at harvest time to confirm this trend

Nanostructured Sensors for Determination of 3-(3,4-Dichlorophenyl)-1,1-Dimethylurea Based in Molecularly Imprinted Polymers (MIPs) Deposited in Screen Printed Carbon Nanotubes

A sensor based on molecularly imprinted polymers (MIP) was developed for determination of 3-(3,4-Dichlorophenyl)-1,1- dimethylurea (diuron). The MIP were synthesized by free radical polymerization in wich diuron acted as template, methacrylic acid (MAA) acted as functional monomer and ethylene glycol dimethacrylate (EGDMA) acted as crosslinker. For construction of the sensor, glassy carbon electrode was modified with Nafion® and MIP/NIP (non imprinted polymer) to see the contribution of MIP, as a film, in the diuron recognition. Differential Pulse Voltammetry was used to the quantification of diuron in a range of response 0.4 - 1.2 V in a PBS (pH=8). All parameters affecting the sensor were optimized. The sensor showed a linear response from 1.00x10-5 to 9.616x10-5 M in PBS 0.1 M (pH=8). The limit of detection was 0.58x10-5 mol L-1. The nanostructured sensor was prepared using carbon nanotubes and showed a 4 times greater response than the glassy carbon, showing promising results

Genetic diversity of HLA system in four populations from Baja California, Mexico: Mexicali, La Paz, Tijuana and rural Baja California

We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 250 Mexicans from the states of Baja California Norte and Baja California Sur living in Mexicali (N = 100), La Paz (N = 75), Tijuana (N = 25) and rural communities (N = 50) to obtain information regarding allelic and haplotypic frequencies. The most frequent haplotypes for the Baja California region include nine Native American and five European haplotypes. Admixture estimates revealed that the main genetic components are European (50.45 ± 1.84% by ML; 42.03% of European haplotypes) and Native American (43.72 ± 2.36% by ML; 40.24% of Native American haplotypes), while the African genetic component was less apparent (5.83 ± 0.98% by ML; 9.36% of African haplotypes)

El Comité Científico Nacional de Arte Rupestre de ICOMOS-España

En enero de 2021 se constituyó el Comité Científico Nacional de Arte Rupestre de ICOMOS-España (CCNAR ICOMOS-España) como un grupo de miembros expertos en estas manifestaciones culturales con el objeto de dinamizar una reflexión rigurosa sobre la gestión de estos bienes culturales   desde los principios emanados de las cartas y convenios internacionales para la gestión del patrimonio cultural. La creación de este Comité Científico Nacional de Arte Rupestre deriva de los objetivos del plan estratégico 2018-2021 del Comité Nacional de ICOMOS-España, que pretende agrupar a sus expertos en grupos de trabajo temáticos para profundizar en los fines de la institución: la identificación, el conocimiento, la documentación, la conservación, la protección, la gestión y la difusión del patrimonio cultural, en este caso en el ámbito español. Ello no supone una restricción local de la institución internacional, bien al contrario, busca reproducir un organigrama reflejo de los Comités Científicos Internacionales con los que se pretende interactuar y establecer una acción coordinada

Factor structure and measurement invariance across various demographic groups and over time for the phq-9 in primary care patients in spain

The Patient Health Questionnaire (PHQ-9) is a widely-used screening tool for depression in primary care settings. The purpose of the present study is to identify the factor structure of the PHQ-9 and to examine the measurement invariance of this instrument across different sociodemographic groups and over time in a sample of primary care patients in Spain. Data came from 836 primary care patients enrolled in a randomized controlled trial (PsicAP study) and a subsample of 218 patients who participated in a follow-up assessment at 3 months. Confirmatory factor analysis (CFA) was used to test one- and two-factor structures identified in previous studies. Analyses of multiple-group invariance were conducted to determine the extent to which the factor structure is comparable across various demo- graphic groups (i.e., gender, age, marital status, level of education, and employment situa- tion) and over time. Both one-factor and two-factor re-specified models met all the pre- established fit criteria. However, because the factors identified in the two-factor model were highly correlated (r = .86), the one-factor model was preferred for its parsimony. Multi-group CFA indicated measurement invariance across different demographic groups and across time. The present findings suggest that physicians in Spain can use the PHQ-9 to obtain a global score for depression severity in different demographic groups and to reliably monitor changes over time in the primary care setting

Normothermic regional perfusion vs. super-rapid recovery in controlled donation after circulatory death liver transplantation

[Background & Aims] Although there is increasing interest in its use, definitive evidence demonstrating a benefit for postmortem normothermic regional perfusion (NRP) in controlled donation after circulatory death (cDCD) liver transplantation is lacking. The aim of this study was to compare results of cDCD liver transplants performed with postmortem NRP vs. super-rapid recovery (SRR), the current standard for cDCD.[Methods] This was an observational cohort study including all cDCD liver transplants performed in Spain between June 2012 and December 2016, with follow-up ending in December 2017. Each donor hospital determined whether organ recovery was performed using NRP or SRR. The propensity scores technique based on the inverse probability of treatment weighting (IPTW) was used to balance covariates across study groups; logistic and Cox regression models were used for binary and time-to-event outcomes.[Results] During the study period, there were 95 cDCD liver transplants performed with postmortem NRP and 117 with SRR. The median donor age was 56 years (interquartile range 45–65 years). After IPTW analysis, baseline covariates were balanced, with all absolute standardised differences <0.15. IPTW-adjusted risks were significantly improved among NRP livers for overall biliary complications (odds ratio 0.14; 95% CI 0.06–0.35, p <0.001), ischaemic type biliary lesions (odds ratio 0.11; 95% CI 0.02–0.57; p = 0.008), and graft loss (hazard ratio 0.39; 95% CI 0.20–0.78; p = 0.008).[Conclusions] The use of postmortem NRP in cDCD liver transplantation appears to reduce postoperative biliary complications, ischaemic type biliary lesions and graft loss, and allows for the transplantation of livers even from cDCD donors of advanced age.[Lay summary] This is a propensity-matched nationwide observational cohort study performed using livers recovered from donors undergoing cardiac arrest provoked by the intentional withdrawal of life support (controlled donation after circulatory death, cDCD). Approximately half of the livers were recovered after a period of postmortem in situ normothermic regional perfusion, which restored warm oxygenated blood to the abdominal organs, whereas the remainder were recovered after rapid preservation with a cold solution. The study results suggest that the use of postmortem normothermic regional perfusion helps reduce rates of post-transplant biliary complications and graft loss and allows for the successful transplantation of livers from older cDCD donors.Peer reviewe

Iron metallurgy via concentrated solar energy

Environmental protection is deeply rooted in current societies. In this context, searching for new environmentally friendly energy sources is one of the objectives of industrial policies in general, and of the metallurgical industries in particular. One of these energy sources is solar energy, which offers a great potential in high temperature applications, such as those required in metallurgy processes, when properly concentrated. In this paper, we propose the utilization of concentrated solar energy in ironmaking. We have studied the utilization of concentrated solar thermal in the agglomeration of iron ore mixtures and in the obtaining of iron via reduction with carbon (and coke breeze). The results from the experiments show the typical phases of the iron ore sinters and the presence of iron through smelting reduction
