Si bien la investigación en Ciencias Sociales conlleva ciertas dificultades propias del mismo proceso de investigación, como la recopilación de entrevistas o el trabajo de campo, también hay dificultades dentro de la misma academia. Existen ciertas barreras para la plena participación de las mujeres tanto en la misma investigación como en puestos de dirección y como lideresas, lo cual a veces se supera con el reconocimiento a la trayectoria de las investigadoras. Al respecto, hay notables casos. Sin embargo, en la misma academia, a las mujeres todavía se les considera a través de perspectivas distintas con relación a los hombres: desde la forma de obtener su plaza o adscripción, sobre su desenvolvimiento en la docencia, hasta la crítica hacia sus ascensos o sus distintas producciones, no sólo por parte de los compañeros, sino también de las compañeras. El covid-19, en todo el tiempo de pandemia, ha exacerbado muchas de estas dificultades, sin mencionar lo que sucede en la vida de la investigadora en el ámbito privado. Por ello, en el artículo se presentan las múltiples dificultades a las que se enfrentan las mujeres investigadoras, pero también se proponen formas para que logren una mayor visibilidad e incorporación dentro de la investigación, tal como el acompañamiento a jóvenes investigadoras, para así lograr una mayor cantidad, pero también calidad, en torno a la investigación hecha por mujeres

The bildungsroman has dominated the Nigerian literary landscape since the 1990s with novels such as Chimamanda N. Adichie’s Purple Hibiscus (2004), Unoma Azuah’s Sky-High Flames (2005), Chika Unigwe’s Night Dancer (2012), and Chinelo Okparanta’s Under the Udala Trees (2015). These coming-of-age stories place a special emphasis on the national evolution of Nigeria. Thus, by delving into such interrelation of the national and personal domains, I propose to theorize Under the Udala Trees as a “bildungsromance,” or novel of affective and romantic development. I use the term “bildungsromance” to describe the growth of Okparanta’s protagonist, Ijeoma, as intrinsically associated with the experiences gathered from her affective attachments both in the public and the private spheres. I will analyze Ijeoma’s sentimental relationships as she discovers and naturalizes her queer identity. For this, I will delve into the negative affects − in the form of fear, shame and guilt (Braidotti 2009, 50) − that influence Ijeoma’s experience as a result of her non-conforming to the dictums of Nigerian customary laws. Ironically, such negative affects will be introduced as tightly associated with “the promise of happiness” (Ahmed 2010, 14). In turn, I shall underline the role of Ijeoma’s intimate and romantic relationships in prompting positive forms of affect such as self-love and pride. These affective experiences allow Ijeoma to acquire a critical perspective towards Nigerian customary laws and their impact on identity formation and on what has been referred to as the “democratisation of the private sphere” (Giddens 1992, 184). Ultimately, I will hinge upon Ijeoma’s awareness of her own affective advancements as a key element in her bildungsromance.

This study describes the life story of two female principals who carry out their work in particularly challenging schools in the Spanish educational context. This work is part of two larger international (ISSPP) and national research projects that aim to study the professional identity of school leaders. In this case, our objective was to analyse the construction of a leadership identity when faced with the challenges of working in a difficult school context, and to identify the main strategies adopted to achieve educational improvement in such adverse situations. The findings reveal that leading with others -- and not over others -- was key to achieving change. Our participating principals developed a style of leadership that is distributed and oriented towards values of social justice in an attempt to eradicate inequality and discrimination in their schools. Being a woman was also a determining factor in this professional performance. Learning from 'the flight of the geese' was the essence of these professional stories, facing challenges with professional values of empathy, active listening, companionship, and commitment. Finally, we discuss the implications of this work for future research and professional practice.

This article delves into the abuses stemming from the Nigerian state forces and their failure to protect Nigerian citizens as illustrated in Yejide Kilanko’s Daughters Who Walk this Path (2012). The novel narrates the struggles undergone by young Morayo as she is repeatedly abused as a child by an elder cousin, Bros T. Here, I seek to trace a parallelism between the instances of physical and affective violence against Morayo and the episodes of “intra-societal violence” (Hill 2012: 15) occurring in Nigeria from the 1980s to the mid-1990s, when the country’s sociopolitical sphere was marked by the social chaos resulting from armed robberies, military coups, rigged elections, and instances of police brutality towards women. I shall analyze such episodes as instances of ‘forced intimacy’ within the public and private spheres, which translates into the impositions of negative forms of affect upon personal and collective development. In this context, the physical and psychological abuses suffered by Morayo will be presented as shaping what Ahmed refers to as one’s “biographies of violence” (2017: 23). My ultimate aim is to trace Morayo’s development of what I will describe as ‘affective resilience’ against the affective forces of the state.

Conclusiones: La interpretación serológica y la ecografía obstétrica permitieron identificar una población de gestantes con la infección a quien se le ofreció el tratamiento disponible, sin embargo, existieron casos de toxoplasmosis congénita en ocasiones fueron fatales o con compromiso neurológico grave en la población estudiada.

Un considerable aumento del monto de deuda pública en Latinoamérica se ha observado en los últimos años. Empleando la metodología de mínimos cuadrados generalizados factibles para datos de panel con efectos fijos, este artículo encuentra que el gasto público, el tipo de cambio real, el nivel de precios y las importaciones son los mayores contribuyentes a la acumulación de deuda. Si bien, se logra comprobar que el gasto público es el mayor detonante, también se demuestra que los periodos de elecciones presidenciales han sido un factor significativo en la constitución de la deuda pública en los países latinoamericanos

Salinity is one of the main factors causing soil deterioration, making it unsuitable for agriculture. It is well documented that the application of halotolerant and halophilic plant growth-promoting bacteria (PGPR: plant growth-promoting rhizobacteria) with biological control activities as an inoculant of cultivated plants offers a biological alternative to the use of agrochemicals, particularly when subjected to salt stress. From this perspective, 70 bacterial strains were isolated from saline soils (sebkha) in arid and semi-arid areas of Eastern Algeria. Three isolates were selected based on their ability to produce bioactive molecules allowing them to promote plant growth, such as hydrolytic enzymes, indole acetic acid (auxin-phytohormone), HCN, NH3, etc. Two of these isolates belonged to the genus Serratia and the third was a halophilic Halomonas bacteria. These bacteria were identified based on their 16S rDNA sequences. Antagonism tests against phytopathogenic fungi were carried out. The identification of the antifungal molecules produced by these bacteria was determined using high-performance liquid chromatography. These bacteria can inhibit mycelial development against phytopathogenic fungi with rates reaching 80.67% against Botrytis cinerea, 76.22% against Aspergillus niger, and 66.67% against Fusarium culmorum for Serratia sp. The strain Halomonas sp. inhibited mycelial growth through the production of volatile substances of Aspergillus niger at 71.29%, Aspergillus flavus at 75.49%, and Penicillium glabrum at a rate of 72.22%. The identification of the antifungal molecules produced by these three bacteria using HPLC revealed that they were polyphenols, which makes these strains the first rhizobacteria capable of producing phenolic compounds. Finally, pot tests to determine the effectiveness of these strains in promoting wheat growth under salinity stress (125 mM, 150 mM, and 200 mM) was carried out. The results revealed that a consortium of two isolates (Serratia sp. and Halomonas sp.) performed best at 125 mM. However, at higher concentrations, it was the halophilic bacteria Halomonas sp. that gave the best result. In all cases, there was a significant improvement in the growth of wheat seedlings inoculated with the bacteria compared to non-inoculated controls.

ABSTRACTConsidering the more frequent and longer drought events due to climate change, improving plant drought tolerance became a priority. The search for plant growth promoting rhizobacteria (PGPR) able to improve plant drought tolerance has been long addressed, but with inconsistent results. Here, we summarize the PGPR mechanisms that improve plant drought tolerance, identify the pitfalls in current PGPR isolation and selection routines, and discuss the key points to define new strategies to get optimal PGPR for plant drought tolerance. Drought and host genotype impact rhizo-communities, and host-mediated selection strategies may be used to obtain a drought-adapted rhizomicrobiome that can be a source for PGPR isolation. Alternatively, an integrated omics-level analysis can improve our knowledge on the mechanisms of rhizomicrobiome construction, and a targeted approach can be designed, which will be focused on key PGP traits. New strategies to build PGPR consortia for improvement of plant drought tolerance are also suggested.

The objective was to study the impacts of the implementation of fish farming projects (fish breeding), the quality of water effluents from these enterprises, in upland streams on properties in the municipalities of Manaus and Iranduba. We chose to monitor some physical-chemical attributes such as turbidity, dissolved oxygen, chlorophyll-a, ammonia, nitrite, nitrate and phosphorus because they are able to establish a relationship between fish farming and the loss of environmental quality of water. For this study, 16 sample units were analyzed, with two collection points each, upstream and downstream in the fish farming enterprises in uplands of continuous land (continuous flow), in two different periods in the year 2016 and 2017. The main variables studied in the analysis stage of an aquatic ecosystem, including fishing grounds, they can be: water temperature, pH, turbidity, concentration of nutrients (nitrite, nitrate and ammonia, total phosphorus), dissolved oxygen, chlorophyll. There was no significant difference in temperature, dissolved oxygen, ammonia and nitrate. There was a significant difference for the depth, turbidity and nitrite parameters. There was a significant difference for phosphorus and pH and no difference was observed for chlorophyll-a. The analyzed parameters were sufficient to demonstrate that the fish farming activity in Igarapé alters turbidity, nitrite and phosphorus and pH. Based on these parameters, better control of water quality in fish farming in Igarapé is suggested as water flow and better quality of the feed offered to fish.

The addition of biostimulants to nutrient solutions of hydroponically grown crops to speed up plant growth and improve plant yield and quality has been attracting more and more attention. This study investigated the effects of wood distillate (WD) addition to hydroponically grown lettuce (Lactuca sativa L.) plants. Two concentrations of WD, 0.2% and 0.5%, were added to the nutrient solution, and biometric (i.e., leaf fresh weight, root fresh weight, root length and root surface area), photosynthetic (i.e., chlorophyll a, chlorophyll b, and carotenoid content) and biochemical (i.e., electrolyte leakage, total polyphenols, total flavonoids, and total antioxidant power content) parameters were evaluated. The effects of WD were hormetic, as the 0.2% concentration stimulated biometric and biochemical parameters, while the 0.5% concentration inhibited plant growth. Based on these results, it can be suggested that the addition of 0.2% WD to the nutrient solution has a stimulating effect on the growth of lettuce plants, and could be a successful strategy to boost the yield of crops grown hydroponically.

Biocides used in antifouling (AF) paints, such as 4,5-dichlorine-2-n-octyl-4-isothiazole-3-one (DCOIT), can gradually leach into the environment. Some AF compounds can persist in the marine environment and cause harmful effects to non-target organisms. Nanoengineered materials, such as mesoporous silica nanocapsules (SiNCs) containing AF compounds, have been developed to control their release rate and reduce their toxicity to aquatic organisms. This study aimed to evaluate the acute toxicity of new nanoengineered materials, SiNC-DCOIT and a silver-coated form (SiNC-DCOIT-Ag), as well as the free form of DCOIT and empty nanocapsules (SiNCs), on the sun coral Tubastraea coccinea. T. coccinea is an invasive species and can be an alternative test organism for evaluating the risks to native species, as most native corals are currently threatened. The colonies were collected from the Alcatrazes Archipelago, SP, Brazil, and acclimatized to laboratory conditions. They were exposed for 96 h to different concentrations of the tested substances: 3.33, 10, 33, and 100 µg L−1 of free DCOIT; 500, 1000, 2000, and 4000 µg L−1 of SiNC; and 74.1, 222.2, 666.7, and 2000 µg L−1 of SiNC-DCOIT and SiNC-DCOIT-Ag. The test chambers consisted of 500 mL flasks containing the test solutions, and the tests were maintained under constant aeration, a constant temperature of 23 ± 2 °C, and photoperiod of 12 h:12 h (light/dark). At the end of the experiments, no lethal effect was observed; however, some sublethal effects were noticeable, such as the exposure of the skeleton in most of the concentrations and replicates, except for the controls, and embrittlement at higher concentrations. Adults of T. coccinea were considered slightly sensitive to the tested substances. This resistance may indicate a greater capacity for proliferation in the species, which is favored in substrates containing antifouling paints, to the detriment of the native species.

Seed priming with synthetic chemicals may be harmful to the environment and human health. Their replacement with bio-based compounds may overcome these concerns. In this study, we assessed the effectiveness of wood distillate (WD) in enhancing in vitro germination of crop plants using basil, chickpea, and lettuce as case studies. Seeds of the three species were soaked for 24 h in 0.25% and 0.17% WD solutions and then left to germinate for 7 days at 20 °C in a dark germination chamber. Seed pre-treatment with 0.25% WD enhanced germination in all tested species, while 0.17% WD stimulated germination in lettuce and chickpea, but not in basil. For lettuce, 0.17% WD worked better than 0.25% WD. Radicle length of basil and chickpea increased following pre-treatment with 0.25% WD, while in lettuce, it increased after pre-treatment with 0.17% WD. Treating seeds with appropriate WD solutions is a potential strategy to improve germination of crop plants.

Lichens have long been considered as composite organisms composed of algae and/or cyanobacteria hosted by a fungus in a mutualistic relationship. Other organisms have been gradually discovered within the lichen thalli, such as multiple algal species, yeasts, or even viruses. Of pivotal relevance is the existence of the lichen microbiome, which is a community of microorganisms that can be found living together on the lichen surface. This community performs a growing number of functions. In this entry, we explore the journey of lichens being considered from a dual partnership to a multi-species symbiotic relationship.

Dextro-transposition of the great arteries (D-TGA) is a congenital heart disease (CHD) classically palliated with atrial switch (ATR-S) and nowadays corrected with arterial switch (ART-S). Our aim was to observe a group of D-TGA patients followed in an adult CHD Outpatient Clinic. We analyzed a group of D-TGA patients born between 1974 and 2001. Adverse events were defined as a composite of death, stroke, myocardial infarction or coronary revascularization, arrhythmia, and ventricular, baffle or significative valvular dysfunction. A total of 79 patients were enrolled, 46% female, mean follow-up of 27±6 years after surgery. ATR-S was performed in 54% and ART-S in 46%; median age at procedure was 13 months and 10 days, respectively. During follow-up, almost all ART-S remained in sinus rhythm versus 64% of ATR-S (p=0.002). The latter group had a higher incidence of arrhythmias (41% versus 3%, p

Desde o início do século XXI que se percebe a necessidade de uma resposta única e singular à criança e à infância. Até então, o contexto sociocultural regia-se por uma lógica adultocentrada, não sendo reconhecido por parte do adulto a incapacidade de adotar a perspetiva da criança. Tal acentua-se com a Contemporaneidade, a sociedade do conhecimento e a vulgarização das TIC a enaltecerem o papel das crianças “nativo digitais”. O hiato geracional confonta pais/cuidadores, docentes, profissionais que atuam na infância e comunidade em geral com a criança competente e de direito. O desafio envolve educadores qualificados, orientações educativas específicas e contextos consagrados às crianças dos 0-3 anos, verdadeiros “lugares de infância”. Através da metodologia de position paper, pretende este artigo sustentar a posição de que esta é a conjuntura ideal para a “emergência” de um novo, revigorado e inclusivo “Sistema Educativo”, aquele que abraça, considera e destaca a CRECHE.

Abstract The state of the art of earthen architecture and vernacular built heritage comprises a complex set of issues that range from fundamental problematic recognition to anthropological and cultural studies and, more recently, to technological and experimental analyses. This paper addresses the development of the field, following the milestones of the international literature and pursuing a reflective-theory approach within a historical framework. It aims to explore the main contributions that have enhanced vernacular heritage and earthen architecture as specific domains, from pioneering public awareness essays to institutional expertise guidelines. Finally, in addition to the literature review process, this paper considers the recent corpus of recommendations from conservation management reference institutions, the updating of the operative problematic of earthen vernacular built heritage, and the relevance of local community involvement in facing increasing challenges.

High salt levels in soil can severely limit plant development and diminish the positive effect of plant-growth-promoting rhizobacteria (PGPR). However, extracts of organisms adapted to high salinity, such as Opuntia ficus-indica (OFI) and Enteromorpha intestinalis (EI), can restore the growth of PGPR. Therefore, we used OFI or EI extracts and their combination with the PGPR Achromobacter xylosoxidans BOA4 to evaluate salt stress relief in tomato (Solanum lycopersicum). The experimental setup consisted of a plant pot trial under greenhouse conditions with 12 treatments: control, irrigation with OFI extract; EI extract; BOA4-inoculated plus OFI extract and BOA4-inoculated plus EI extract under no salinity or salinity conditions (150 mM NaCl). The percentage of germination, and plant’s fresh and dry weight were registered 30 and 46 days after sowing. At 46 days, the ratio between proline and glutamic acid concentration (PR/GA) was determined, expecting high PR/GA ratios in plants more responsive to salt stress since proline is an osmolyte mainly synthesized from glutamate. The results showed that 52% of the control seeds under salt stress germinated, a figure that was increased to 92% in OFI-treated seeds. Tomato plants were shown to be very sensitive to salt stress since the dry weight was ca. one fourth that of the plants grown without salinity. However, EI or BOA4 plus EI stimulated plant biomass by ca. 3 times compared to the control with salt, restoring plant biomass to values comparable to those of control plants grown without salinity. The joint treatments with BOA4 and EI or OFI caused distinct PR/GA levels in plant tissues. An inverse relationship between the sum of relative shoot proline and glutamic acid contents and shoot biomass accumulation was observed, namely in treatments accumulating more biomass under no salinity and salinity conditions. This indicates that the proline/glutamate pathway represents a carbon sink that is needed to fight stress and is competing with the carbon flow used for growth.

Wild mushrooms and truffles (MT) are important resources, which can contribute to the socioeconomic sustainability of forestry ecosystems. However, not all wild MT are edible. Fast, cheap, and reliable methods that distinguish wild MT species (including the deadly ones) can contribute to valuing these important forest resources. Here, we tested if wild MT species, and their edibility, could be distinguished based on their aroma profiles (i.e., smellprints). For that, we combined the use of the electronic nose with classification models (linear discriminant analysis (LDA) and partial least squares discriminant analysis (PLS-DA)) to distinguish between 14 wild MT species (including edible and non-edible species) collected in Portugal. The 14 wild MT species could be accurately distinguished using LDA (93% accuracy), while the edible and non-edible species could be accurately distinguished using both LDA and PLS-DA (97% and 99% accuracy, respectively). Keeping in mind that our methodological design’s feasibility was verified using a small sample, the data show the potential of the combined use of the electronic nose with discriminant analysis to distinguish wild MT species and their edibility based on their aromatic profile. Although a larger dataset will be necessary to develop a quick and reliable identification method, it shows potential to be as accurate as the identification performed by mycologists and molecular biology, yet requiring less technical training, and the analyses are cheaper and faster.

The overuse of chemical pesticides and fertilizers in crop farming has led to a decrease in crop quality and negative impacts on soil and the environment. It is crucial to adopt alternative strategies to maintain soil and environmental quality while enhancing crop growth and yield. To explore this, a study was conducted under greenhouse conditions to investigate the effect of Rhizobium tropici CIAT 899 alone, as well as in association with mycorrhizae (Rhizophagus irregularis) and endophytic fungus (Serendipita indica), on the growth, yield, and nutrient status of snap bean plants. At harvest, the rhizobial strain CIAT 899 demonstrated the highest effectiveness. It significantly increased the number of nodules in both Contender and Garrafal Enana varieties by 6.97% and 14.81%, respectively, compared with the control without inoculation. Furthermore, the results indicated that co-inoculation of Rhizobium and symbiotic fungi had positive effects on nitrogen content, phosphorus availability, and overall plant growth. Regardless of the variety, plants inoculated with R. tropici CIAT 899 and Serendipita indica exhibited the highest values for plant growth parameters. This combination resulted in 168% and 135% increases in root dry biomass, as well as 140% and 225% increases in the number of pods for Contender and Garrafal Enana, respectively, compared with the control at harvest. Additionally, this study highlights the potential benefits of combining R. tropici with either Serendipita indica or Rhizophagus irregularis in terms of nitrogen and phosphorus uptake. These symbiotic microorganisms demonstrated synergistic interactions with snap bean plants, leading to improved mineral nutrition and enhanced growth. Overall, these findings suggest that utilizing these symbiotic microorganisms can effectively enhance the mineral nutrition and growth of snap bean plants.

Este artículo tiene como objetivo central determinar el impacto del endurecimiento de la frontera México-Estados Unidos, particularmente por el cierre parcial de la frontera por el Covid-19 –la conglomeración de migrantes en la ciudad y la limitación de movilidad transfronteriza– en la recepción de remesas en Ciudad Juárez. Para ello se empleó el método de mínimos cuadrados ordinarios y el análisis de correlación de Pearson y Spearman para determinar la relación que guardan las remesas con el número de cruces entre la frontera y el número de inmigrantes en la ciudad. Los resultados encontrados evidencian que la única variable estadísticamente significativa fue el cierre parcial de la frontera, a través de la disminución de los cruces, la cual tiene relación negativa con la recepción de remesas en la localidad, es decir, a menor número de cruces mayor es la recepción de remesas.

BackgroundCoastal areas in Guinea-Bissau and elsewhere in West Africa are bordered by mangrove forests. In several of these places, swaths of mangrove forest have been removed and the landscape has been technologically adapted for the production of mangrove rice-a regionally important staple. However, the effects of global warming, in particular sea-level rise, pose challenges to these socioecological environments. In this context, knowledge appears as an important resource and knowing what knowledge has been produced and which perspectives have guided that production may inform future responses to climate change. We have developed a systematic literature review protocol focusing on the main question: "How have mangrove forest and mangrove rice spaces been represented in the literature on Guinea-Bissau?" The main hypothesis is that although they occupy contiguous, interrelated and interactant spaces in coastal environments, mangrove forests and mangrove rice have been studied and analyzed independently in the literature.MethodsThis is a protocol for conducting a systematic review that will include academic and non-academic literature in Portuguese, English and French. The academic literature will be retrieved from both Web of Science and Scopus using Boolean expressions. The non-academic literature will be accessed from relevant institutions, specialized libraries, and reference lists of previously selected items. Data extraction will follow a standard procedure based on an information sheet. Our analysis will be both qualitative (inductive and deductive coding, content analysis) and quantitative (word clouds, descriptive statistics and statistical testing).DiscussionThis systematic review will provide information about the conceptual framework that has been produced through research, policymaking, and conservation and development programs in the management of coastal areas. This study will identify the limitations of previous approaches and contribute to both future research and strategies for planning adaptation to climate change. Finally, the outputs will add to broader debates about people-nature coexistence and climate change adaptation and mitigation.

COVID-19 pandemic has unquestionably influenced care of acute myocardial infarction (AMI). Still, its impact on patients (pts) characteristics, presentation, treatment, and outcomes remains not well established in late pandemic times. To address this issue, we performed a prospective study of type-1 AMI pts admitted in a tertiary care hospital. Pts were enrolled during 6-months in 2019 (n=122; pre-COVID-19 (PC) group) and in 2021 (n=196; late-COVID-19 (C) group). Data was based on pts interview and review of medical records. Age and gender distribution, as well as ST/Non-ST-Elevation Myocardial Infarction (STEMI/NSTEMI) proportion and access to coronariography and revascularization were similar between groups. C pts presented more pre-existing established cardiovascular disease (CVD) (43% vs 30%; p=0,03); more frequent description of typical chest pain (94% vs 84%; p=0,002); higher levels of pain intensity, in a 0-10 scale (8±2 vs 7±2; p=0,02); higher frequencies of AMI complications (27% vs 15%; p=0,01) and worse Killip (K) class evolution (K≥2 in 22% C vs 13% PC pts; p=0,05). In conclusion, late pandemic AMI pts presented worse in-hospital outcomes in our study, though pre-hospital and hospital care were comparable to pre-pandemic times. Covid pts had a higher burden of pre-existing established CVD and a more typical and intense symptom presentation. Therefore, it can be hypothesized that "sicker" pts continued to look for help when presenting AMI symptoms, while "less sick" pts and the ones with less typical and intense symptoms possibly avoided contact with health care services during late pandemic period.

In recent decades, Higher Education has undergone a gradual but progressive transformation worldwide. Globalisation has promoted convergence mechanisms between states to achieve common standards in Higher Education; among them, those who seek to guarantee the quality of university teaching. The aim of this research is to analyse the most recent studies carried out on the impact that new teaching evaluation systems have on academics. For this purpose, a systematic review of the literature has been developed in which three different databases have been used (Wos, Scopus and ERIC). After searching and applying the inclusion / exclusion criteria, a total of 15 documents were selected. The articles were subjected to a thematic analysis and also of their characteristics. Among the most outstanding results, the development of fragmented academic identities that have an impact on the work and the wellbeing of the academics is detected. Also, the presence of contradictory opinions on teaching evaluation. Likewise, possible alternatives on teaching evaluation systems are mentioned. To conclude, a series of future lines of research are outlined, such as the consideration of more varied samples that allow more detailed comparisons between various variables, the development of longitudinal studies, and the promotion of alternatives to the current systems of evaluation.

Terfezia arenaria is a desert truffle native to the Mediterranean Basin region, highly appreciated for its nutritional and aromatic properties. Despite the increasing interest in this desert truffle, T. arenaria is not listed as an edible truffle authorized for trade in the European Union. Therefore, our objective was to showcase T. arenaria’s nutritional and chemical composition and volatile profile. The nutritional analysis showed that T. arenaria is a good source of carbohydrates (67%), proteins (14%), and dietary fibre (10%), resulting in a Nutri-Score A. The truffle’s volatile profile was dominated by eight-carbon volatile compounds, with 1-octen-3-ol being the most abundant (64%), and 29 compounds were reported for the first time for T. arenaria. T. arenaria’s nutritional and chemical compositions were similar to those of four commercial mushroom and truffle species, while the aromatic profile was not. An electronic nose corroborated that T. arenaria‘s aromatic profile differs from that of the other four tested mushroom and truffle species. Our data showed that T. arenaria is a valuable food resource with a unique aroma and an analogous composition to meat, which makes it an ideal source for plant-based meat products. Our findings could help promote a sustainable future exploitation of T. arenaria and ensure the quality and authenticity of this delicacy.

Abstract The tumor suppressor FANCD1/BRCA2 is crucial for DNA homologous recombination repair (HRR). BRCA2 biallelic pathogenic variants result in a severe form of Fanconi anemia (FA) syndrome, whereas monoallelic pathogenic variants cause mainly hereditary breast and ovarian cancer predisposition. For decades, the co-occurrence in trans with a clearly pathogenic variant led to assume that the other allele was benign. However, here we show a patient with biallelic BRCA2 (c.1813dup and c.7796 A > G) diagnosed at age 33 with FA after a hypertoxic reaction to chemotherapy during breast cancer treatment. After DNA damage, patient cells displayed intermediate chromosome fragility, reduced survival, cell cycle defects, and significantly decreased RAD51 foci formation. With a newly developed cell-based flow cytometric assay, we measured single BRCA2 allele contributions to HRR, and found that expression of the missense allele in a BRCA2 KO cellular background partially recovered HRR activity. Our data suggest that a hypomorphic BRCA2 allele retaining 37–54% of normal HRR function can prevent FA clinical phenotype, but not the early onset of breast cancer and severe hypersensitivity to chemotherapy.

Introducción: El diagnóstico de cáncer genera una inestabilidad emocional y en muchos casos esto imposibilita un afrontamiento adecuado. El afrontamiento es el esfuerzo cognitivo y conductual constantemente cambiantes que se desarrollan para manejar las demandas específicas como el diangóstico oncológico. El objetivo de la presente investigación fue identificar las estrategias de afrontamiento en un grupo de pacientes con cáncer, en un Hospital de referencia nacional. Metodología: Este estudio transversal, se realizó en el Hospital Eugenio Espejo de Quito, Ecuador, período enero a junio del 2018, con una muestra no probabilística, de pacientes con neoplasias, se registraron variables demográficas, clínicas, y el test de afrontamiento de 40 preguntas CSI “El inventario de estrategias de afrontamiento (CSI). Se utiliza estadística descriptiva univariada.y bivariada. Resultados: Se analizan 47 casos, 74% mujeres, de edad promedio 55 años. De instrucción secundaria completa en el 38 % de los casos. Las Estrategias de Afrontamiento que se presentaron en el 70% de los pacientes fueron: Reestructuración Cognitiva (REC) y Evitación de problemas (EVP), en el 15% se presentó "Resolución de problemas" (REP). Las Estrategias de Afrontamiento en hombres fueron REP con el 57%, mientras que la Expresión Emocional (EEM) se presentó en mujeres en el 86%. En los primeros 6 meses el 77% usa la EEM; de 7 a 12 meses el 19% a la estrategia de Autocrítica (AUC); de 1 a 2 años con un 17% estrategia de Pensamiento Desiderativo (PSD); de 3 o más años con un 14% corresponde a Resolución de Problemas (REP). Conclusión: Las estrategias de afrontamiento se utilizan en gran proporción en los primeros 6 meses del diagnóstico del cáncer, luego de lo cual las estrategias disminuyen por debajo del 20%.

Summary: Background: Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide. Methods: A multimethods analysis was performed as part of the GlobalSurg 3 study—a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital. Findings: Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3·85 [95% CI 2·58–5·75]; p

(1) Background: Increasing salinity, further potentiated by climate change and soil degradation, will jeopardize food security even more. Therefore, there is an urgent need for sustainable agricultural practices capable of maintaining high crop yields despite adverse conditions. Here, we tested if wheat, a salt-sensitive crop, could be a good reservoir for halotolerant bacteria with plant growth-promoting (PGP) capabilities. (2) Methods: We used two agricultural soils from Algeria, which differ in salinity but are both used to grow wheat. Soil halotolerant bacterial strains were isolated and screened for 12 PGP traits related to phytohormone production, improved nitrogen and phosphorus availability, nutrient cycling, and plant defence. The four ‘most promising’ halotolerant PGPB strains were tested hydroponically on wheat by measuring their effect on germination, survival, and biomass along a salinity gradient. (3) Results: Two halotolerant bacterial strains with PGP traits were isolated from the non-saline soil and were identified as Bacillus subtilis and Pseudomonas fluorescens, and another two halotolerant bacterial strains with PGP traits were isolated from the saline soil and identified as B. megaterium. When grown under 250 mM of NaCl, only the inoculated wheat seedlings survived. The halotolerant bacterial strain that displayed all 12 PGP traits and promoted seed germination and plant growth the most was one of the B. megaterium strains isolated from the saline soil. Although they both belonged to the B. megaterium clade and displayed a remarkable halotolerance, the two bacterial strains isolated from the saline soil differed in two PGP traits and had different effects on plant performance, which clearly shows that PGP potential is not phylogenetically determined. (4) Conclusions: Our data highlight that salt-sensitive plants and non-saline soils can be reservoirs for halotolerant microbes with the potential to become effective and sustainable strategies to improve plant tolerance to salinity. However, these strains need to be tested under field conditions and with more crops before being considered biofertilizer candidates.

Eimeriid coccidians represent one of the largest groups of parasitic unicellular organisms and comprise many species of veterinary and medical importance. The aim of this work is to provide information, as complete as possible, concerning the oocyst phase of the species of coccidians (Apicomplexa: Eimeriorina) with four sporocysts, which were reported in marine fish. For each species, the accepted scientific name and respective authorities, its synonyms, reported hosts, site of infection (organ), and geographic distribution have been assembled. Available information on morphology (oocyst, sporocyst, and sporozoite) and GenBank accession numbers were also compiled. A total of 100 species of coccidians were described and reported from 60 families of marine fishes. Most species have been described from marine teleosts, with only 14 of the species described from marine elasmobranchs. Most of the species reported in marine fish belong to the genera Eimeria and Goussia, and only a handful belong to the genera Epieimeria, Calyptospora, and Crystallospora. Although marine coccidians have began to be described for more than one century, the collection of genetic data on marine fish coccidians only started in the 2010s and remains largely disconnected from the morphological analysis of specimens, which is available for only six formally described species.

Once considered the most speciose mostly azooxanthellate scleractinian group, the family Caryophylliidae is found to be highly polyphyletic based on molecular data and is undergoing a process of systematic revision. High‐throughput sequencing methods coupled with morphological analyses have facilitated revision of several scleractinian lineages, including the aforementioned family. In previous studies that relied on few mitochondrial and nuclear markers, the caryophylliid genera Stephanocyathus and Vaughanella were phylogenetically recovered in separate clades from the lineage that includes the type genus of the family, Caryophyllia, which is considered the 'true' Caryophylliidae. To help untangle the relationship among taxa of this family, here a new deep‐sea scleractinian family (Stephanocyathidae Vaga, Cairns & Kitahara fam. nov.) is proposed based on phylogenomic reconstructions coupled with molecular features, specifically gene order, of the complete mitochondrial genome. Evolutionary reconstructions were based on both mitochondrial and nuclear ultraconserved elements (UCEs) and exon loci data sets and confirmed the divergent position of the genera Stephanocyathus and Vaughanella. The new family shows a specific gene transposition in the mitochondrial genome, not present in the 'true' caryophylliid lineage, but instead already observed for the species Paraconotrochus antarcticus, recovered as sister taxon of the here proposed new family. Although its phylogenetic position is unknown, the genus Ericiocyathus is also added to the new family, based on macromorphological similarities. This study represents a step forward in our understanding of deep‐sea corals relationships and provide further information (e.g., mitochondrial gene order) that will aid in future efforts of assessing the systematic of caryophylliid lineages.

Food safety is a significant challenge worldwide, from plantation to cultivation, especially for perishable products such as tomatoes. New eco-friendly strategies are needed, and beneficial microorganisms might be a sustainable solution. This study demonstrates bacteria activity in the tomato plant rhizosphere. Further, it investigates the rhizobacteria’s structure, function, and diversity in soil. Rhizobacteria that promote the growth and development of tomato plants are referred to as plant growth-promoting bacteria (PGPR). They form a series of associations with plants and other organisms in the soil through a mutualistic relationship where both parties benefit from living together. It implies the antagonistic activities of the rhizobacteria to deter pathogens from invading tomato plants through their roots. Some PGPR are regarded as biological control agents that hinder the development of spoilage organisms and can act as an alternative for agricultural chemicals that may be detrimental to the health of humans, animals, and some of the beneficial microbes in the rhizosphere soil. These bacteria also help tomato plants acquire essential nutrients like potassium (K), magnesium (Mg), phosphorus (P), and nitrogen (N). Some rhizobacteria may offer a solution to low tomato production and help tackle food insecurity and farming problems. In this review, an overview of soil-inhabiting rhizobacteria focused on improving the sustainable production of Solanum lycopersicum.

Abstract Few studies have tested how plant quality and the presence of competitors interact in determining how herbivores choose between different leaves within a plant. We investigated this in two herbivorous spider mites sharing tomato plants: Tetranychus urticae, which generally induces plant defenses, and Tetranychus evansi, which suppresses them, creating asymmetrical effects on coinfesting competitors. On uninfested plants, both herbivore species preferred young leaves, coinciding with increased mite performance. On plants with heterospecifics, the mites did not prefer leaves on which they had a better performance. In particular, T. urticae avoided leaves infested with T. evansi, which is in agreement with T. urticae being outcompeted by T. evansi. In contrast, T. evansi did not avoid leaves with the other species, but distributed itself evenly over plants infested with heterospecifics. We hypothesize that this behavior of T. evansi may prevent further spread of T. urticae over the shared plant. Our results indicate that leaf age determines within‐plant distribution of herbivores only in absence of competitors. Moreover, they show that this distribution depends on the order of arrival of competitors and on their effects on each other, with herbivores showing differences in behavior within the plant as a possible response to the outcome of those interactions.

Abstract Background Commonly known as sun-coral, Tubastraea tagusensis is an azooxanthellate scleractinian coral that successfully invaded the Southwestern Atlantic causing significant seascape changes. Today it is reported to over 3500 km along the Brazilian coast, with several rocky shores displaying high substrate coverage. Apart from its singular invasiveness capacity, the documentation and, therefore, understanding of the role of symbiotic microorganisms in the sun-coral invasion is still scarce. However, in general, the broad and constant relationship between corals and microorganisms led to the development of co-evolution hypotheses. As such, it has been shown that the microbial community responds to environmental factors, adjustment of the holobiont, adapting its microbiome, and improving the hosts’ fitness in a short space of time. Here we describe the microbial community (i.e. Bacteria) associated with sun-coral larvae and adult colonies from a locality displaying a high invasion development. Results The usage of high throughput sequencing indicates a great diversity of Bacteria associated with T. tagusensis, with Cyanobacteria, Proteobacteria, Bacteroidetes, Actinobacteria, Planctomycetes, and Firmicutes corresponding to the majority of the microbiome in all samples. However, T. tagusensis’ microbial core consists of only eight genera for colonies, and, within them, three are also present in the sequenced larvae. Overall, the microbiome from colonies sampled at different depths did not show significant differences. The microbiome of the larvae suggests a partial vertical transfer of the microbial core in this species. Conclusion Although diverse, the microbiome core of adult Tubastraea tagusensis is composed of only eight genera, of which three are transferred from the mother colony to their larvae. The remaining bacteria genera are acquired from the seawater, indicating that they might play a role in the host fitness and, therefore, facilitate the sun-coral invasion in the Southwestern Atlantic.
