A comprehensive RNA-Seq-based gene expression atlas of the summer squash (Cucurbita pepo) provides insights into fruit morphology and ripening mechan…
2021
[EN] Background Summer squash (Cucurbita pepo: Cucurbitaceae) are a popular horticultural crop for which there is insufficient genomic and transcriptomic information. Gene expression atlases are crucial for the identification of genes expressed in different tissues at various plant developmental stages. Here, we present the first comprehensive gene expression atlas for a summer squash cultivar, including transcripts obtained from seeds, shoots, leaf stem, young and developed leaves, male and female flowers, fruits of seven developmental stages, as well as primary and lateral roots. Results In total, 27,868 genes and 2352 novel transcripts were annotated from these 16 tissues, with over 18,0…
Influence of substrate and temperature on the biodegradation of polyester-based materials: Polylactide and poly(3-hydroxybutyrate-co-3-hydroxyhexanoa…
2020
[EN] The extended use of polymers from renewable resources such as aliphatic polyesters or polyhydroxyalkanoates boosted the necessity to understand their behaviour in an end-of-life scenario. Although they can be degraded in reasonable shorter times than traditional polymers, understanding the degradation mechanisms under dissimilar conditions will contribute to further developments in this field. This work aimed to study the effect of temperature and substrate in the degradation of polylactide (PLA) and poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBH) in a simulated laboratory scale to ascertain their contribution, separately or in combination. For this purpose, nine parallel degradat…
Poly (lactic acid)/D-limonene/ZnO bio-nanocomposites with antimicrobial properties
2022
[EN] Antimicrobial films of poly (lactic acid) (PLA)/D-limonene/zinc oxide (ZnO)-based bio-nanocomposites were prepared via melt compounding and subsequent thermocompression. D-limonene was incorporated at concentrations of 10 or 20 wt%, and ZnO pure nanoparticles and those organically modified with oleic acid (O-ZnO), with an average diameter of 13.5 nm, were included at concentrations of 3, 5, and 8 wt%. The plasticizing effect of D-Limonene was corroborated by a decrease in the glass transition temperature compared to pure PLA. The presence of ZnO and O-ZnO in the PLA matrix promoted a slight increase in the degree of crystallinity due to its nucleant performance. Although ZnO and O-ZnO …

RNA-seq transcriptome analysis provides candidate genes for resistance to Tomato leaf cur New Delhi virus in melon
2022
[EN] Tomato leaf curl New Delhi virus (ToLCNDV) emerged in the Mediterranean Basin in 2012 as the first DNA bipartite begomovirus (Geminiviridae family), causing severe yield and economic losses in cucurbit crops. A major resistance locus was identified in the wild melon accession WM-7 (Cucumis melo kachri group), but the mechanisms involved in the resistant response remained unknown. In this work, we used RNA-sequencing to identify disease-associated genes that are differentially expressed in the course of ToLCNDV infection and could contribute to resistance. Transcriptomes of the resistant WM-7 genotype and the susceptible cultivar Piñonet Piel de Sapo (PS)(C. melo ibericus group) in ToLC…
El consentimiento informado en los pacientes privados de libertad
2013
Fundamento y objetivo: El consentimiento informado (CI) médico constituye hoy el pilar fundamental sobre el que se asienta la asistencia sanitaria a la población. Cualquier persona competente y capaz para tomar decisiones puede dar o negar su permiso para cualquier intervención médica que le afecte, incluso una intervención que vaya a salvar su vida, siempre que esa decisión no amenace intereses de terceros. A pesar de este principio general hay un grupo de personas, que son los presos, que tienen restringida su aplicación y no pueden decidir libremente sobre aceptar o rechazar un tratamiento médico en casos extremos, cuando su salud o su vida corran peligro. El objetivo del trabajo es resp…
Los nombres del hambre. La construcción de las categorías médicas de la malnutrición
2012
Durant el període entre guerres, la fisiologia de la nutrició va incorporar un ampli coneixement experimental sobre calories, nutrients, vitamines i minerals. Les catàstrofes bèl·liques i les crisis econòmiques del període entre guerres varen estendre la fam en moltes zones del món. Les situacions extremes (refugiats, malalts, aturats, internats als camps de concentració) van propiciar les estratègies de racionament i també l’estudi dels símptomes de la fam, la seua dimensió clínica, els tipus de malalties i la malnutrició aguda. El present article analitza la construcció d’un saber mèdic sobre les conseqüències patològiques de la fam i la construcció mèdica del concepte de malnutrició.
Encapsulation of Vitamins A and E as Spray-Dried Additives for the Feed Industry
2020
Encapsulated fat-soluble powders containing vitamin A (VA) and E (VE) were prepared as a feasible additive for extruded feed products. The effect of the encapsulating agents (Capsul-CAP®
