El Pliensbachiense de la Rama Aragonesa de la Cordillera Ibérica: Análisis de facies y establecimiento de secuencias

The Pliensbachian of the Aragonese branch of the Iberian Chain is represented by Almonacid de la Cuba, Cerro del Pez and Barahona formations. These sediments are constituted by marls and limestone organized in shallowingupward sequences. All of them are represented in the lower part by marls and mudstone that change to wackestone and packstone. The top of the sequence is a ferruginous crust, generally bioturbated. This represents the decrease in the sedimentation velocity and a shallowing event. The sediments were deposited in a carbonate ramp, changing from middle to outer environments. The most shallowing facies were located in the south, where there is an evidence of the developing of reefal facies. The deeper facies were deposited in the north, corresponding to open environments. This work shows the correlation of six thirdorder shallowing upward sequences in the Pliensbachian sediments. The origin of these sequences is related to sea level oscillations and conditioned by autocyclic processes

Biochemical and genetic implications of the slow ripening phenotype in peach fruit

The peach [Prunus persica L. (Batsch)] slow ripening (SR) trait is a mutation preventing the normal fruit ripening process. It is determined by a single Mendelian gene (Sr/sr) located on linkage group 4, where only homozygous individuals for a recessive allele (sr) show the SR phenotype and are generally discarded from breeding programs. Ripening-related traits such as fruit weight, firmness loss, ethylene production, ACO activity, sugars and organic acids composition, malondialdehyde, antioxidant capacity and total phenolic content were evaluated in a segregating population for the SR trait during two consecutive harvest seasons and at different maturity stages. Although there is no commercial value for the slow ripening (srsr) individuals, our results demonstrate that a heterozygous combination involving sr and another allele at this locus (Sr2) showed interesting traits including a longer harvest window and improved postharvest behaviour if harvested at the appropriate maturity (IAD ≥ 2). All these traits seem to be linked to a delayed ripening behaviour mediated, in turn, by a lower ethylene production capacity and an altered sugar (mainly sucrose) and organic acid accumulation/utilisation on-tree. The selection of this allelic combination could be an easy and efficient strategy to obtain new peach cultivars with potentially improved shelf life.info:eu-repo/semantics/acceptedVersio

Complementary IT resources for enabling technological opportunism

This study examines the use of information technologies (ITs), IT human capital, the level of IT vendor support, and their joint effects on firm''s sensing and responding to IT changes (technological opportunism). Using data from the U.S. and Spain, the results suggest that IT use and the firm''s IT human capital are the main drivers of technological opportunism (TO). The effect of IT vendor support on TO is country dependent, with a U-shaped effect in the U.S. and no effect in Spain. IT vendor support can have positive effects on TO if the firm invests in IT human capital

Análisis del orden de entrada en el sistema de franquicia español

Desde las perspectivas de marketing, dirección estratégica y organización industrial se ha analizado la sostenibilidad de las ventajas competitivas (Barney, 1991; Hamel y Prahalad, 1994; Carpenter y Nakamoto, 1994; Kalyanaram et al., 1995; Covin et al., 1999). Así, la teoría del orden de entrada explica que aquellas empresas que entran antes en un mercado obtienen ventajas frente a las siguientes entrantes (Michael, 2003). Por tanto, esta investigación, centrada en el sector de la franquicia, analiza la influencia del momento de entrada en los resultados empresariales.From marketing, strategic management and industrial organization perspectives, it has been analyzed the sustainability of competitive advantages (Barney, 1991; Hamel and Prahalad, 1994; Carpenter and Nakamoto, 1994; Kalyanaram et al., 1995; Covin et al., 1999). The first-mover advantage explains that those firms that entry before in the market gain more advantages than the followers (Michael, 2003). Therefore, this research, focused on the franchised distribution system, analyzes the influence of the timing of entry on profitability

An insight into the hormonal interplay regulating pigment changes and colour development in the peel of ‘Granny Smith’,‘OPAL®’and ‘Royal Gala’ Apples

Three apple cultivars with different peel colour and known ripening dynamics were examined throughout development and on-tree ripening to unravel how the hormonal crosstalk may influence colour changes. Our results indicate that the colour of ripe apples in ‘Granny Smith’ and ‘Opal®’ cultivars was primarily influenced by chlorophyll levels masking the contribution of other pigments, whilst the development of red colour in the ‘Royal Gala’ was not only due to an important loss of chlorophyll during ripening but also to anthocyanins accumulation. The interplay amongst indole-3-acetic acid (IAA), ethylene and abscisic acid (ABA) seemed to control pigment content during the later stages of development, indicating that variations in the hormonal profile contribute to colour differences in ripe apples. In ‘Granny Smith’ apples, basal levels of IAA, ethylene and ABA were associated with the inhibition of chlorophyll loss, which was responsible for its green colour, despite the presence of high carotenoid levels. In contrast, the peel of ‘Opal®’ and ‘Royal Gala’ apples underwent a degreening process facilitated by the IAA-mediated activation of ethylene metabolism, in a crosstalk facilitated by MdARF5. The accumulation of anthocyanins in the peel of ‘Royal Gala’ apples seemed to be regulated in an ethylene-dependent manner, with MdMYB1 acting as the mediator between ethylene signalling and the anthocyanins biosynthesis and vacuolar transport pathways. On the other hand, the decline in carotenoid content during fruit development in the three cultivars appeared to be regulated at the catabolic level through ABA and its derivatives and possibly also facilitated by ethylene-mediated mechanisms. Notably, chlorophyll levels, crucial for the observed colour changes, were likely controlled by MdGLK1, a transcription factor involved in chloroplast biogenesis, working in coordination with ethylene-dependent catabolic enzymes. Overall, understanding the cultivar-specific hormonal regulation of apple colour provides valuable insights for developing preharvest and postharvest strategies to ensure an optimal fruit colour aligned with consumer preferences.European Regional Development Fund (ERDF) through the national project PID2020-117607RR-I00 (ENVIRONAPPLE)

Ocular related emergencies in Spain during the COVID-19 pandemic, a multicenter study

Purpose: To evaluate ophthalmological emergencies (OE) during the COVID-19 pandemic comparing them with the same period of the previous year. Methods: Retrospective observational study of all OE visits in four tertiary hospitals in Spain comparing data from March 16th to April 30th, 2020 (COVID-19 period) and the same period of 2019 (pre-COVID-19 period). Severity of the conditions was assessed following Channa et al. publication. Data on demographics, diagnosis and treatments were collected from Electronic Medical Records. Results: During lockdown, OE significantly declined by 75.18%, from 7, 730 registered in the pre-COVID-19 period to 1, 928 attended during the COVID-19 period (p < 0.001). In 2019, 23.86% of visits were classified as emergent, 59.50% as non-emergent, and 16.65% could not be determined. In 2020, the percentage of emergent visits increased up to 29.77%, non-emergent visits significantly decreased to 52.92% (p < 0.001), and 17.31% of the visits were classified as “could not determine”. During the pandemic, people aged between 45 and 65 years old represented the largest attending group (37.89%), compared to 2019, where patients over 65 years were the majority (39.80%). In 2019, most frequent diagnosis was unspecified acute conjunctivitis (11.59%), followed by vitreous degeneration (6.47%), and punctate keratitis (5.86%). During the COVID-19 period, vitreous degeneration was the first cause for consultation (9.28%), followed by unspecified acute conjunctivitis (5.63%) and punctate keratitis (5.85%). Conclusions: OE visits dropped significantly during the pandemic in Spain (75.18%), although more than half were classified as non-urgent conditions, indicating a lack of understanding of the really emergent ocular pathologies among population. © 2021, The Author(s)

Primary care utilisation patterns among an urban immigrant population in the Spanish National Health System

<p>Abstract</p> <p>Background</p> <p>There is evidence suggesting that the use of health services is lower among immigrants after adjusting for age and sex. This study takes a step forward to compare primary care (PC) utilisation patterns between immigrants and the native population with regard to their morbidity burden.</p> <p>Methods</p> <p>This retrospective, observational study looked at 69,067 individuals representing the entire population assigned to three urban PC centres in the city of Zaragoza (Aragon, Spain). Poisson models were applied to determine the number of annual PC consultations per individual based on immigration status. All models were first adjusted for age and sex and then for age, sex and case mix (ACG System^®).</p> <p>Results</p> <p>The age and sex adjusted mean number of total annual consultations was lower among the immigrant population (children: IRR = 0.79, p < 0.05; adults: IRR = 0.73, p < 0.05). After adjusting for morbidity burden, this difference decreased among children (IRR = 0.94, p < 0.05) and disappeared among adults (IRR = 1.00). Further analysis considering the PC health service and type of visit revealed higher usage of routine diagnostic tests among immigrant children (IRR = 1.77, p < 0.05) and a higher usage of emergency services among the immigrant adult population (IRR = 1.2, p < 0.05) after adjusting for age, sex and case mix.</p> <p>Conclusions</p> <p>Although immigrants make lower use of PC services than the native population after adjusting the consultation rate for age and sex, these differences decrease significantly when considering their morbidity burden. These results reinforce the 'healthy migration effect' and discount the existence of differences in PC utilisation patterns between the immigrant and native populations in Spain.</p
