Diverse projected climate change scenarios affect the physiology of broccoli plants to different extents.

Climate change caused by global warming involves crucial plant growth factors such as atmospheric CO2 concentration, ambient temperature or water availability. These stressors usually co-occur, causing intricate alterations in plant physiology and development. This work focuses on how elevated atmospheric CO2 levels, together with the concomitant high temperature, would affect the physiology of a relevant crop, such as broccoli. Particular attention has been paid to those defence mechanisms that contribute to plant fitness under abiotic stress. Results show that both photosynthesis and leaf transpiration were reduced in plants grown under climate change environments compared to those grown under current climate conditions. Furthermore, an induction of carbohydrate catabolism pointed to a redistribution from primary to secondary metabolism. This result could be related to a reinforcement of cell walls, as well as to an increase in the pool of antioxidants in the leaves. Broccoli plants, a C3 crop, grown under an intermediate condition showed activation of those adaptive mechanisms, which would contribute to coping with abiotic stress, as confirmed by reduced levels of lipid peroxidation relative to current climate conditions. On the contrary, the most severe climate change scenario exceeded the adaptive capacity of broccoli plants, as shown by the inhibition of growth and reduced vigour of plants. In conclusion, only a moderate increase in atmospheric CO2 concentration and temperature would not have a negative impact on broccoli crop yields.

Necrosis laminar cortical cerebral como manifestación de estatus epiléptico inducido por consumo crónico de alcohol / Cortical laminar necrosis as a manifestation of status epilepticus induced by chronic alcohol abuse

Introducción: la necrosis laminar cortical es un término radiológico que describe la presencia de lesiones hiperdensas de localización cerebral, las cuales siguen una distribución giriforme y se observan con mayor sensibilidad en los estudios de resonancia magnética cerebral (RM). Esta condición patológica, que afecta a la corteza del cerebro, suele ser secundaria a una depleción de sus fuentes energéticas como consecuencia de hipoxia cerebral, alteraciones metabólicas, hipoglicemia, falla renal o hepática, intoxicaciones o infecciones. Presentación del caso: se reporta el caso de un hombre de 23 años, con antecedente de consumo crónico de alcohol, quien ingresó al servicio de urgencias de nuestra institución con un estado epiléptico. El estudio de resonancia magnética cerebral demostró la presencia de una necrosis laminar cortical con posterior déficit neurocognitivo y funcional. Conclusión: si se consideran las secuelas neurológicas potenciales asociadas a un estado epiléptico, relacionadas con necrosis laminar cortical cerebral, es necesario hacer un diagnóstico etiológico precoz, así como una atención terapéutica temprana a los pacientes.

Introduction: Cortical laminar necrosis (CLN) is radiologically defined as high-intensity cortical lesions on T1-weighted MRI images that follow a gyral distribution in the brain. Histopathologically, this pathological condition is characterized by necrosis of the cortex involving neurons, glial cells, and blood vessels. It is usually triggered by hypoxia, metabolic alterations, drugs, intoxications, or infections. Case description: We report the case of a 23-year-old man with a history of chronic alcohol abuse who was admitted to our institution with status epilepticus. The brain magnetic resonance imaging performed on this patient showed cortical laminar necrosis associated with subsequent neurocognitive deficits. Conclusion: Due to the potential neurological sequelae secondary to status epilepticus in relation to cortical laminar necrosis as permanent brain damage, it is necessary to provide early diagnosis and treatment for these patients.

Assessment of Black Rot in Oilseed Rape Grown under Climate Change Conditions Using Biochemical Methods and Computer Vision.

Global warming is a challenge for plants and pathogens, involving profound changes in the physiology of both contenders to adapt to the new environmental conditions and to succeed in their interaction. Studies have been conducted on the behavior of oilseed rape plants and two races (1 and 4) of the bacterium Xanthomonas campestris pv. campestris (Xcc) and their interaction to anticipate our response in the possible future climate. Symptoms caused by both races of Xcc were very similar to each other under any climatic condition assayed, although the bacterial count from infected leaves differed for each race. Climate change caused an earlier onset of Xcc symptoms by at least 3 days, linked to oxidative stress and a change in pigment composition. Xcc infection aggravated the leaf senescence already induced by climate change. To identify Xcc-infected plants early under any climatic condition, four classifying algorithms were trained with parameters obtained from the images of green fluorescence, two vegetation indices and thermography recorded on Xcc-symptomless leaves. Classification accuracies were above 0.85 out of 1.0 in all cases, with k-nearest neighbor analysis and support vector machines performing best under the tested climatic conditions.

Novel Vegetation Indices to Identify Broccoli Plants Infected With Xanthomonas campestris pv. campestris.

A rapid diagnosis of black rot in brassicas, a devastating disease caused by Xanthomonas campestris pv. campestris (Xcc), would be desirable to avoid significant crop yield losses. The main aim of this work was to develop a method of detection of Xcc infection on broccoli leaves. Such method is based on the use of imaging sensors that capture information about the optical properties of leaves and provide data that can be implemented on machine learning algorithms capable of learning patterns. Based on this knowledge, the algorithms are able to classify plants into categories (healthy and infected). To ensure the robustness of the detection method upon future alterations in climate conditions, the response of broccoli plants to Xcc infection was analyzed under a range of growing environments, taking current climate conditions as reference. Two projections for years 2081-2100 were selected, according to the Assessment Report of Intergovernmental Panel on Climate Change. Thus, the response of broccoli plants to Xcc infection and climate conditions has been monitored using leaf temperature and five conventional vegetation indices (VIs) derived from hyperspectral reflectance. In addition, three novel VIs, named diseased broccoli indices (DBI1-DBI3), were defined based on the spectral reflectance signature of broccoli leaves upon Xcc infection. Finally, the nine parameters were implemented on several classifying algorithms. The detection method offering the best performance of classification was a multilayer perceptron-based artificial neural network. This model identified infected plants with accuracies of 88.1, 76.9, and 83.3%, depending on the growing conditions. In this model, the three Vis described in this work proved to be very informative parameters for the disease detection. To our best knowledge, this is the first time that future climate conditions have been taken into account to develop a robust detection model using classifying algorithms.

Creating our own Black Books: keeping a journal as a loom of life.

Jung's The Black Books are annotations of his inner world after his process of self-experimentation, which he called his 'confrontation with the unconscious'. They preceded The Red Book in which, as a scribe, he reworked his initial notes and drawings. This was the raw material for the work that Jung developed over the rest of his life. From his experimentation, he formulated the method of active imagination and the concept of the transcendent function, a psychological function that creates symbols and integrates the unconscious contents in consciousness. Jung invites us, with his experience, to write and paint our own Black Books and to explore our inner images. With this proposal to keep a journal as a loom of life, we welcome his invitation, which allows us to weave and integrate the visible and invisible substances of our lives. Our intention for the journalling is to provide a space for the unfolding of the individuation process. In Jung's invitation we see that a life that does not confront itself cannot be realized as such.

Les Livres Noirs de Jung sont des annotations sur son monde intérieur suite à son processus d'expérimentation sur lui-même, qu'il a appelé sa « confrontation avec l'inconscient ¼. Ils ont précédé le Livre Rouge dans lequel, comme un scribe, il retravailla ses notes et dessins initiaux. Ce fut le matériel brut pour le travail que Jung développa jusqu'à la fin de sa vie. A partir de son expérimentation, il formula la méthode d'imagination active et le concept de fonction transcendante, une fonction psychologique qui crée des symboles et intègre les contenus inconscients dans la conscience. Par son expérience Jung nous invite à écrire et à peindre nos propres Livres Noirs et à explorer nos images intérieures. Avec cette proposition de tenir un journal en tant que métier à tisser de la vie, nous accueillons son invitation, qui nous permet de tisser et d'intégrer les substances visibles et invisibles de nos vies. Notre intention dans cette expérience de tenir un journal est de fournir un espace pour le déploiement du processus d'individuation. Dans l'invitation de Jung nous voyons qu'une vie qui ne se confronte pas à elle-même ne peut pas se réaliser en tant que telle.

Los Libros Negros de Jung son anotaciones de su mundo interno tras su proceso de auto experimentación, al que denominó su "confrontación con lo inconsciente". Estos antecedieron al Libro Rojo, en el que como un escriba reelaboraba sus notas y dibujos iniciales. Esta fue la materia prima del trabajo que Jung desarrolló por el resto de su vida. A partir de su experimentación formuló el método de la imaginación activa y el concepto de la función transcendente, función psicológica creadora de símbolos e integradora de contenidos inconscientes en la conciencia. Jung nos invita con su experiencia a escribir nuestros propios Libros Negros y a explorar nuestras imágenes interiores. Con nuestra propuesta de llevar un diario como telar de la vida hemos acogido esta invitación, que nos permite, tejer e integrar la sustancia visible e invisible de nuestras vidas. Nuestra intención con el diario es facilitar un espacio para el desenvolvimiento del proceso de individuación. En la invitación de Jung vemos que una vida que no se confronte consigo misma, no se puede realizar como tal.

Os Livros Negros de Jung são anotações de seu mundo interior após seu processo de autoexperimentação, que ele chamou de seu "confronto com o inconsciente". Eles precederam o Livro Vermelho no qual, como escriba, ele reformulou suas notas e desenhos iniciais. Esta foi a matéria-prima para o trabalho que Jung desenvolveu pelo resto de sua vida. A partir de sua experimentação, ele formulou o método da imaginação ativa e o conceito de função transcendente, uma função psicológica que cria símbolos e integra os conteúdos inconscientes na consciência. Jung nos convida, com sua experiência, a escrever e pintar nossos próprios Livros Negros e explorar nossas imagens internas. Com esta proposta de manter um diário como um tear da vida, saudamos seu convite, que nos permite tecer e integrar as substâncias visíveis e invisíveis de nossas vidas. Nossa intenção para o diário é fornecer um espaço para o desdobramento do processo de individuação. No convite de Jung, vemos que uma vida que não se confronta não pode ser realizada como tal.

Phenotyping Plant Responses to Biotic Stress by Chlorophyll Fluorescence Imaging.

Photosynthesis is a pivotal process in plant physiology, and its regulation plays an important role in plant defense against biotic stress. Interactions with pathogens and pests often cause alterations in the metabolism of sugars and sink/source relationships. These changes can be part of the plant defense mechanisms to limit nutrient availability to the pathogens. In other cases, these alterations can be the result of pests manipulating the plant metabolism for their own benefit. The effects of biotic stress on plant physiology are typically heterogeneous, both spatially and temporarily. Chlorophyll fluorescence imaging is a powerful tool to mine the activity of photosynthesis at cellular, leaf, and whole-plant scale, allowing the phenotyping of plants. This review will recapitulate the responses of the photosynthetic machinery to biotic stress factors, from pathogens (viruses, bacteria, and fungi) to pests (herbivory) analyzed by chlorophyll fluorescence imaging both at the lab and field scale. Moreover, chlorophyll fluorescence imagers and alternative techniques to indirectly evaluate photosynthetic traits used at field scale are also revised.

RNA-seq analysis and fluorescence imaging of melon powdery mildew disease reveal an orchestrated reprogramming of host physiology.

The cucurbit powdery mildew elicited by Podosphaera xanthii is one of the most important limiting factors in cucurbit production. Our knowledge of the genetic and molecular bases underlying the physiological processes governing this disease is very limited. We used RNA-sequencing to identify differentially expressed genes in leaves of Cucumis melo upon inoculation with P. xanthii, using RNA samples obtained at different time points during the early stages of infection and their corresponding uninfected controls. In parallel, melon plants were phenotypically characterized using imaging techniques. We found a high number of differentially expressed genes (DEGs) in infected plants, which allowed for the identification of many plant processes that were dysregulated by the infection. Among those, genes involved in photosynthesis and related processes were found to be upregulated, whereas genes involved in secondary metabolism pathways, such as phenylpropanoid biosynthesis, were downregulated. These changes in gene expression could be functionally validated by chlorophyll fluorescence imaging and blue-green fluorescence imaging analyses, which corroborated the alterations in photosynthetic activity and the suppression of phenolic compound biosynthesis. The powdery mildew disease in melon is a consequence of a complex and multifaceted process that involves the dysregulation of many plant pathways such as primary and secondary metabolism.

Detection of Bacterial Infection in Melon Plants by Classification Methods Based on Imaging Data.

The bacterium Dickeya dadantii is responsible of important economic losses in crop yield worldwide. In melon leaves, D. dadantii produced multiple necrotic spots surrounded by a chlorotic halo, followed by necrosis of the whole infiltrated area and chlorosis in the surrounding tissues. The extent of these symptoms, as well as the day of appearance, was dose-dependent. Several imaging techniques (variable chlorophyll fluorescence, multicolor fluorescence, and thermography) provided spatial and temporal information about alterations in the primary and secondary metabolism, as well as the stomatal activity in the infected leaves. Detection of diseased leaves was carried out by using machine learning on the numerical data provided by these imaging techniques. Mathematical algorithms based on data from infiltrated areas offered 96.5 to 99.1% accuracy when classifying them as mock vs. bacteria-infiltrated. These algorithms also showed a high performance of classification of whole leaves, providing accuracy values of up to 96%. Thus, the detection of disease on whole leaves by a model trained on infiltrated areas appears as a reliable method that could be scaled-up for use in plant breeding programs or precision agriculture.

Use of multicolour fluorescence imaging for diagnosis of bacterial and fungal infection on zucchini by implementing machine learning.

Zucchini (Cucurbita pepo L.) is a cucurbitaceous plant ranking high in economic importance among vegetable crops worldwide. Pathogen infections cause alterations in plants primary and secondary metabolism that lead to a significant decrease in crop quality and yield. Such changes can be monitored by remote and proximal sensing, providing spatial and temporal information about the infection process. Remote sensing can also provide specific signatures of disease that could be used in phenotyping and to detect a pest, forecast its evolution and predict crop yield. In this work, metabolic changes triggered by soft rot (caused by Dickeya dadantii) and powdery mildew (caused by Podosphaera fusca) on zucchini leaves have been studied by multicolour fluorescence imaging and by thermography. The fluorescence parameter F520/F680 showed statistically significant differences between infected (with D. dadantii or P. fusca) and mock-control leaves during the whole period of study. Artificial neural networks, logistic regression analyses and support vector machines trained with a set of features characterising the histograms of F520/F680 images could be used as classifiers, discriminating between healthy and infected leaves. These results show the applicability of multicolour fluorescence imaging on plant phenotyping.

Multicolor Fluorescence Imaging as a Candidate for Disease Detection in Plant Phenotyping.

The negative impact of conventional farming on environment and human health make improvements on farming management mandatory. Imaging techniques are implemented in remote sensing for monitoring crop fields and plant phenotyping programs. The increasingly large size and complexity of the data obtained by these techniques, makes the implementation of powerful mathematical tools necessary in order to identify informative parameters and to apply them in precision agriculture. Multicolor fluorescence imaging is a useful approach for the study of plant defense responses to stress factors at bench scale. However, it has not been fully applied to plant phenotyping. This work evaluates the possible application of multicolor fluorescence imaging in combination with thermography for the particular case of zucchini plants affected by soft-rot, caused by Dickeya dadantii. Several statistical models -based on logistic regression analysis (LRA) and artificial neural networks (ANN)- were obtained for the experimental system zucchini-D. dadantii, which classify new samples as "healthy" or "infected." The LRA worked best in identifying high dose-infiltrated leaves (in infiltrated and non-infiltrated areas) whereas ANN offered a higher accuracy at identifying low dose-infiltrated areas. To assess the applicability of these results to cucurbits in a more general way, these models were validated for melon infected by the same pathogen, achieving accurate predictions for the infiltrated areas. The values of accuracy achieved are comparable to those found in the literature for classifiers identifying other infections based on data obtained by different techniques. Thus, MCFI in combination with thermography prove useful at providing data at lab scale that can be analyzed by machine learning. This approach could be scaled up to be applied in plant phenotyping.

Un caso de deleción parcial 1p36. 1 y trisomía parcial 6p diagnosticadas por cariotipo / A case of partial 1p36. 1 deletion and partial trisomy 6p diagnosed by karyotype

La deleción de la región cromosómica 1p36 es una de las anomalías subteloméricas más frecuentes y causa rasgos dismórficos distintivos. Por otro lado, la trisomía distal del brazo corto del cromosoma 6 es una anormalidad cromosómica poco frecuente de fenotipo variable. Objetivo: Presentar el caso de un paciente con ambas alteraciones cromosómicas, y resaltar la vigencia e importancia del cariotipo como herramienta diagnóstica en dismorfología. Caso clínico: Lactante de 2 meses de edad con múltiples anomalías craneofaciales, hemangioma en la nuca, fosita sacra, acortamiento rizomélico, pies y manos pequeños, criptorquidia unilateral izquierda e hipotonía. Además, antecedente de restricción del crecimiento intrauterino. Producto del octavo embarazo de una mujer G8A7C1 de 28 años. Con estos hallazgos inespecíficos en el fenotipo se solicitó cariotipo que mostró una deleción parcial de 1p36.1 y una trisomía parcial de cromosoma 6p. Conclusión: El cariotipo convencional sigue siendo una herramienta importante para el etiológico en pacientes con anomalías congénitas (múltiples), mostrando en este caso una deleción parcial de 1p36.1 y una trisomía parcial de cromosoma 6p, alteraciones cromosómicas estructurales.

The deletion of chromosomal region 1p36 is one of the most common sub-telomeric microdeletion syndromes and has distinctive dysmorphic features. On the other hand, partial trisomy of the short arm of chromosome 6 is a rare chromosomal abnormality with a variable phenotype. Objective: To report a case with both chromosome abnormalities, and to highlight the importance of the karyotype as a diagnostic tool in dysmorphology. Clinical case: The case of is presented of a two month-old infant with several craniofacial anomalies, neck haemangioma, sacral pit, rhizomelic shortening, small hands and feet, left unilateral cryptorchidism, and hypotonia. The infant also suffered intrauterine growth restriction and is the product of the eighth pregnancy of a 28 years old woman. Due to the unspecific findings in phenotype, a karyotype was requested, which showed a partial deletion of 1p36.1 and a partial trisomy of chromosome 6. Conclusion: The development of new techniques in molecular biology has improved diagnostic possibilities in medical genetics. However, the traditional karyotype remains as an important diagnostic tool in patients with multiple congenital anomalies.

Picturing pathogen infection in plants.

Several imaging techniques have provided valuable tools to evaluate the impact of biotic stress on host plants. The use of these techniques enables the study of plant-pathogen interactions by analysing the spatial and temporal heterogeneity of foliar metabolism during pathogenesis. In this work we review the use of imaging techniques based on chlorophyll fluorescence, multicolour fluorescence and thermography for the study of virus, bacteria and fungi-infected plants. These studies have revealed the impact of pathogen challenge on photosynthetic performance, secondary metabolism, as well as leaf transpiration as a promising tool for field and greenhouse management of diseases. Images of standard chlorophyll fluorescence (Chl-F) parameters obtained during Chl-F induction kinetics related to photochemical processes and those involved in energy dissipation, could be good stress indicators to monitor pathogenesis. Changes on UV-induced blue (F440) and green fluorescence (F520) measured by multicolour fluorescence imaging in pathogen-challenged plants seem to be related with the up-regulation of the plant secondary metabolism and with an increase in phenolic compounds involved in plant defence, such as scopoletin, chlorogenic or ferulic acids. Thermal imaging visualizes the leaf transpiration map during pathogenesis and emphasizes the key role of stomata on innate plant immunity. Using several imaging techniques in parallel could allow obtaining disease signatures for a specific pathogen. These techniques have also turned out to be very useful for presymptomatic pathogen detection, and powerful non-destructive tools for precision agriculture. Their applicability at lab-scale, in the field by remote sensing, and in high-throughput plant phenotyping, makes them particularly useful. Thermal sensors are widely used in crop fields to detect early changes in leaf transpiration induced by both air-borne and soil-borne pathogens. The limitations of measuring photosynthesis by Chl-F at the canopy level are being solved, while the use of multispectral fluorescence imaging is very challenging due to the type of light excitation that is used.

Temporal and Spatial Resolution of Activated Plant Defense Responses in Leaves of Nicotiana benthamiana Infected with Dickeya dadantii.

The necrotrophic bacteria Dickeya dadantii is the causal agent of soft-rot disease in a broad range of hosts. The model plant Nicotiana benthamiana, commonly used as experimental host for a very broad range of plant pathogens, is susceptible to infection by D. dadantii. The inoculation with D. dadantii at high dose seems to overcome the plant defense capacity, inducing maceration and death of the tissue, although restricted to the infiltrated area. By contrast, the output of the defense response to low dose inoculation is inhibition of maceration and limitation in the growth, or even eradication, of bacteria. Responses of tissue invaded by bacteria (neighboring the infiltrated areas after 2-3 days post-inoculation) included: (i) inhibition of photosynthesis in terms of photosystem II efficiency; (ii) activation of energy dissipation as non-photochemical quenching in photosystem II, which is related to the activation of plant defense mechanisms; and (iii) accumulation of secondary metabolites in cell walls of the epidermis (lignins) and the apoplast of the mesophyll (phytoalexins). Infiltrated tissues showed an increase in the content of the main hormones regulating stress responses, including abscisic acid, jasmonic acid, and salicylic acid. We propose a mechanism involving the three hormones by which N. benthamiana could activate an efficient defense response against D. dadantii.

Spatial and temporal dynamics of primary and secondary metabolism in Phaseolus vulgaris challenged by Pseudomonas syringae.

Many defense mechanisms contribute to the plant immune system against pathogens, involving the regulation of different processes of the primary and secondary metabolism. At the same time, pathogens have evolved mechanisms to hijack the plant defense in order to establish the infection and proliferate. Localization and timing of the host response are essential to understand defense mechanisms and resistance to pathogens (Rico et al. 2011). Imaging techniques, such as fluorescence imaging and thermography, are a very valuable tool providing spatial and temporal information about a series of plant processes. In this study, bean plants challenged with two pathovars of Pseudomonas syringae have been investigated. Pseudomonas syringae pv. phaseolicola 1448A and P. syringae pv. tomato DC3000 elicit a compatible and incompatible interaction in bean, respectively. Both types of host-pathogen interaction triggered different changes in the activity of photosynthesis and the secondary metabolism. We conclude that the combined analysis of leaf temperature, chlorophyll fluorescence and green fluorescence emitted by phenolics allows to discriminate compatible from incompatible P. syringae-Phaseolus vulgaris interactions in very early times of the infection, prior to the development of symptoms. These can constitute disease signatures that would allow an early identification of emerging plagues in crops.

Recovery of fingerprints and identification of a dismembered body: A crime of passion / Recuperación de huellas digitales e identificación de cadáver desmembrado: crimen pasional

The body of a young woman was dismembered and placed in several plastic bags and left on a public road. Her death was the result of a crime of passion. Upon medico-legal examination, no skin was found on the palmar side of the distal and medial phalanges of all finger pads on both hands (which were also dismembered). Through the process of finger pad recovery, it was possible to find tissues that had adhered to the body and reposition the exactly on each finger to recover fingerprints. Finally, the victim was identified using the conventional fingerprinting process.

El cadáver de una mujer joven fue fragmentado y envuelto en varias bolsas plásticas para luego ser abandonado en la vía pública; su muerte está relacionada con un crimen pasional. Al momento del abordaje médico legal se encontró que los dedos de las dos manos ­estas últimas también desmembradas del cuerpo­ presentaban ausencia de piel en la cara palmar de las falanges distal y media (pulpejos). Mediante el proceso de recuperación de pulpejos se logró la restauración de los tejidos que fueron encontrados adheridos al cuerpo y su reubicación exacta en cada dedo para la posterior recuperación de huellas digitales; finalmente, mediante el proceso convencional dactiloscópico, se logró la identificación de la persona.
