Magnétisme et supraconductivité dans les pnictures de fer étudiés par diffusion Raman

La recente decouverte de supraconductivite dans les pnictures de fer ouvre un nouveau champ d'investigation du mecanisme d'appariement des electrons donnant lieu a des hautes temperatures critiques. Dans ces systemes, le magnetisme et la supraconductivite sont des phases en competition, ou le dopage x destabilise l'ordre magnetique au profit de l'ordre supraconducteur. Un regime de coexistence entre ces deux ordres est present pour une certaine gamme de dopage dans le compose Ba(Fe1-xCox)2As2, que nous avons etudie par diffusion inelastique de la lumiere. Nous nous sommes interesses a l'interaction entre les degres de liberte structuraux, magnetiques et electroniques. L'etude des excitations vibrationnelles du cristal montre le fort couplage spin-phonon, a travers le dedoublement d'un mode de phonon dans les plans fer-arsenic amplifie par l'anisotropie planaire des degres de spin, et le fort couplage electron-phonon, via l'asymetrie significative du mode de phonon de l'arsenic. L'evolution du continuum des excitations electroniques a travers la transition magnetique et supraconductrice traduit, d'une part, l'ouverture du gap d'onde de densite de spin, et d'autre part, que le gap supraconducteur est de symetrie s-anisotrope. Apres avoir identifie separement l'impact de chacune des transitions magnetique et supraconductrice sur nos spectres, nous nous sommes interesses au regime de coexistence entre les deux ordres. Nos resultats illustrent une competition pour les memes etats electroniques au niveau de Fermi entre ces deux ordres, qui s'etablissent sur differentes zones de la surface de Fermi.
Three New Species of Hydrobryum (Podostemaceae) from Laos

grow in rapids and waterfalls in the seasonal tropics and subtropics (van Steenis 1981). Members of the family adhere to rock surfaces by specialized roots and/or holdfasts and are submerged in the fast currents in the rainy season. They become exposed (emergent) and flower in the dry season (Cook & Rutishauser 2007). Subfamily Podostemoideae, the largest among the three subfamilies, comprises 47 genera with ca. 280 species, and is distributed on all three tropical continents (Koi et al. 2012). The morphology of the subfamily is also remarkably diverse in the presence/absence and form of the root, length of the shoot, form and complexity of the leaves, number of tepals and stamens, number of ribs on the capsule and number of ovules (Cook & Rutishauser 2007). Hydrobryum, the largest genus of the subfamily with 30 species in 13 genera in Asia, is widely distributed from Japan and China (Fujian, Yunnan) through northeastern India and Nepal. Thailand is the most species-rich country (16 species) (Kato 2018), followed by Laos (Koi & Kato 2012, 2015). Hydrobryum in Laos has drawn attention only recently. Koi & Kato (2012, 2015) recognized 11 species, of which seven were new, two were new combinations based on transfers from Diplobryum, and two were new records. The new species are characterized mainly by roots, holdfasts, bracts, stamens, ovary locules, and ovules. Koi & Kato (2018) described two new species of Hydrobryum from Laos. They were characterized by prominent holdfasts or ribbon-like roots. In 2016 we found three populations of Hydrobryum in central Laos that we were unable to identify. Like most other congeners, they shared crustose roots, which are present elsewhere in Hanseniella and Thawatchaia, allies of Hydrobryum, three species of Zeylanidium and several African genera and in some species in other genera, such as Djinga, Ledermanniella, and Saxicolella (Cook & Rutishauser 2007, Kato et al. 2015). However, the three unknown species differed from each other and from other congeners in characteristics of the bracts and flowers. Based on morphological data and phylogenetic relationships, we describe them as new species. Floristically, Laos is as rich in species of Hydrobryum (with 16 species; see key to species) as adjacent Three New Species of Hydrobryum (Podostemaceae) from Laos
Precedente horizontal de facto en el Tribunal Constitucional

The purpose of this paper is to describe the practice of the Constitutional Court to invoke and / or follow, de facto, its own precedents. To describe this phenomenon, we distinguish simple and complex variants of this practice. Among the first, we examine judgments where tests, standards, parameters or judgments of constitutionality are invoked or enunciated; judgments that make own concepts or doctrinal categories developed in previous sentences of said Judiciary; and judgments that give account of the jurisprudential framework existing in a certain subject. From the perspective of complex variants, the work accounts for at least four modalities: judgments that explain the existence of a binding precedent; those that explain that there is an applicable precedent, but that it must be replaced; judgments in which the minority vote directly or indirectly questions the majority to deviate from the precedent that is considered binding and where we observe the more dense developments and justifications on the part of the TC; and cases in which a precedent seeks to update an earlier one, without substantively modifying it.

EFFECTS OF HIGH DIETARY COPPER SUPPLEMENTATION ON THE COPPER ACCUMULATION AND TOTAL COPPER CONTENT IN FATTENING PIGS

2018) Abstract. The objective of this current study was to investigate the effects of high dietary copper supplementation on the tissue copper deposition, distribution, and total copper concentration in fattening pigs. A total of 24 (Landrace × Large white × Duroc) pigs with an average initial body weight (BW) of 30 ± 1.05 kg were selected for the current experiment. At the beginning of the experiment, the pigs were randomly divided into four treatment groups with three replicate pens per treatment and two pigs per replicate and arranged in accordance to a completely randomized design based on the BW. The four treatment administered were as follows: 10 mg/kg, 45 mg/kg, 135 mg/kg, and 225 mg/kg of copper. The result indicates that the copper content in the liver, kidney, and heart increased with the increase in dietary copper composition. There was no significant difference in the copper content of the different visceral tissues in the 10 mg/kg treatment group. However, when the copper levels increased to 45 mg/kg and 135 mg/kg, the copper content in the liver was significantly higher than that in the other visceral tissues ( P < 0.05). At 225 mg/kg dietary copper, there was a significant increase in the copper content of the foreleg muscle. There was no significant difference in copper content of the rib bones, tibia bones, and femur bone marrow copper accumulation between the 10 mg/kg copper and the 45 mg/kg copper fed pigs. In addition, there was no significant difference in the brain, blood, cerebellum, and skin copper content within all the treatment groups. Therefore, dietary copper levels increased with the increase in total copper accumulation in pigs. Hence, higher dietary copper supplementation increased liver, kidney, heart, fur, bones, bone marrow copper accumulation and total copper levels in fattening
EarthLife Consortium: Supporting digital paleobiology

Paleobiology is a classic example of a ‘longtail’ discipline, with the large majority of paleobiological data collected by individuals organized into tight guilds of specialists. Most paleobiologists have a domain of expertise centered on a particular set of organisms (or even on particular fossilized body parts within organisms), a geographic region, and a time period or timescale. For example, one paleobiologist might be an expert on leaves and seeds from the Paleogene of North America (leaving the fossil pollen and other microfossils to other specialists) (e.g. Wing et al. 2009), another might specialize in stable isotope measurements from bones and teeth (e.g. DeSantis et al. 2009), while a third might be a specialist in marine foraminifera, working with oceansediment cores collected from across the world (e.g. barker et al. 2005). These scientists also pursue varied research agendas, both as individuals and research teams.

Plastome Phylogenetics of Tribe Eriachneae and Evolution of C4 Photosynthesis in Subfamily Micrairoideae (Poaceae)

Abstract Tribe Eriachneae in subfamily Micrairoideae is one of the least explored of the ca. 22 C4 lineages in the grass family (Poaceae). Whereas many C4 lineages are more species-rich, more morphologically disparate, and wider ranging than their C3 sisters, Eriachneae has fewer species, less disparity, and covers a far smaller geographical area than its C3 sister tribe Isachneae. Tribe Micraireae, which is C3 and sister to Eriachneae and Isachneae, occupies habitats more similar to C4 Eriachneae than C3 Isachneae. Evolutionary analyses within the subfamily are hindered by the lack of a phylogenetic framework for any substantial sample of species. Additionally, only a handful of members of Micrairoideae have been tested for photosynthetic pathway. This study presents the first well-resolved phylogeny of Eriachneae based on full plastome sequences from almost half of the species in the tribe. Photosynthetic pathway is tested for 47 species representing all three tribes of Micrairoideae using carbon isotopes to test the assumption that C4 is restricted to Eriachneae. Habitat preferences among the tribes are estimated using bioclimatic data, with multivariate analyses showing that habitats of Micraireae and Eriachneae are more similar to each other than either is to Isachneae, and the range of environments is greater in Isachneae than in Eriachneae. All measured Eriachneae are confirmed to be C4, and all Isachneae are C3. Evolutionary interpretation of these results is necessarily preliminary, and greater phylogenetic sampling in Isachneae is needed to estimate diversification rates and ancestral habitats, but subfamily Micrairoideae appears to be an interesting exception to general patterns of C4 evolution in grasses.
Comparative Investigations on Tomato Leaf Disease Detection and Classification Using CNN, R-CNN, Fast R-CNN and Faster R-CNN

This composition bargains with the Tomato leaf infection discovery and classification utilizing different strategies like Convolutional Neural Network (CNN), Regions with CNN (R-CNN), Fast R-CNN and Faster R-CNN. The main issue in the agricultural sector is leaf diseases, which have an impact on crop yield and financial gain. Early detection of leaf diseases in plants is essential to prevent losses to the agricultural sector. There are several tomato leaf diseases that affect the crop’s leaves, including the Mosaic virus, Early Blight, Healthy, Septoria leaf, and Bacterial spot. Using deep learning algorithms and image processing methods, we can identify the diseases in tomato leaves using developing deep learning approaches. The implementation procedures in our proposed work involves data collection, pre-processing, training, feature extraction, testing, and classification utilising the Visual Geometry Group (VGG 16) to identify damaged or healthy leaves. VGG 16 is incorporated to categorise the leaves as healthy or diseased based on the data and Regression’s boundary box method is adopted. Therefore, using Faster RCNN, a model is created to identify and categorise diseases from every image of a tomato leaf that is used as an input, providing a forecast with a considerably greater degree of accuracy. We obtain an accuracy of approximately 98% after fitting the collected features into the neural network over 20 iterations.
First detection and molecular identification of the zoonotic Anaplasma capra in deer in France

Cervids are known to be reservoir of zoonotic tick-transmitted bacteria. The aim of this study was to perform a survey in a wild fauna reserve to characterize Anaplasma species carried by captive red deer and swamp deer. Blood from 59 red deer and 7 swamp deer was collected and analyzed over a period of two years. A semi-nested PCR that targets the 23S rRNA was performed to detect and characterise Anaplasma spp. and determine zoonotic species presence. Anaplasma phagocytophilum was identified in 14/59 deer (23.7%) but not in swamp deer. Few sequences could not be assigned to any particular species based on the 23S rRNA sequences. Nested PCR targeting 16S rRNA, gltA and groEL genes and sequencing analysis detected a recently reported zoonotic species, Anaplasma capra in red deer as well as in swamp deer. This is the first reporting of the tick-borne zoonotic bacterium A. capra in France, a species otherwise described only in China and Japan, in goats, sheep, deer and japanese serows. Even if this bacterium may have been introduced in the Park with infected imported animals, its local epidemiological cycle through tick transmission seems possible as locally born deer were found infected. Diagnostic methods, especially molecular ones, should take into account the potential infection of animals and humans with this species.

Nickel Conductive yarn was used, which embroidered in straight and zigzag stitch types with different length of stitch and 1,2 and 3 lines of threads. the obtained resulted, showed that the lowest value of R(Ω) was 1.24 Ω. with straight stitch types with 3 lines of threads with 5mm of stitch length, the number of stitches lines of thread influences on resistance mean values as 2. 721Ω, 2. 54Ω and 2.31 Ωfor the 1, 2 and 3 lines of threads respectively. Means of R (Ω) were 1.83 , 2.03 and 2.80 Ω of the length of stitches 3 mm, 5mm and 7 mm significant respectively The nickel conductive yarn could be embroidered on a prototype T-shirt to be a connector between the temperature sensor and screen. This embedded system based on conductive thread could find possible application in medical applications.
General characterization of regeneration in Aeolosoma viride

Regeneration has long attracted scientists for its potential to restore lost, damaged or aged tissues and organs. A wide range of studies have conducted on different model organisms on both cellular and molecular levels. Current evidences suggest that a variety of regenerative strategies are developed and used by different species, and their regenerative strategies are highly correlated to their reproductive methods. Our present work focused on the freshwater annelid Aeolosoma viride, which reproduces by paratonic fission and is capable of complete regeneration. We found out that A. viride can regenerate both anterior and posterior end, even with only 3 segments remained. This process is characterized by epimorphosis that involves large amount of cell proliferation which drives the formation of blastema. Cell proliferation and regeneration successful ratio were significantly decreased when treated with microtubule inhibitor taxol or Avi-tubulin dsRNA, which confirmed that cell proliferation served as a key event during regeneration. Together, our data described the regenerative processes of A. viride, which includes high level of cell proliferation and the formation of blastema. Furthermore, our findings demonstrated A. viride as a potential model for the study of regeneration.
Genetically Encoded Neural Activity Indicators

Recent years have witnessed the fascinating development of imaging approaches to studying neural activities; this progress has been based on an influx of ideas and methods from molecular biology and optical engineering. Here we review the design and application of genetically encoded indicators for calcium ions, membrane potential and neurotransmitters. We also summarize common strategies for the design and optimization of genetically encoded neural activity indicators.
Role of Adipokines in Development of Metabolic Syndrome

Visceral adipose tissue releases a variety of adipokines which together determine a comprehensive cardiometabolic risk profile. Estrogen deficiency leads to central fat deposition in postmenopausal women. However, premenopausal women are also running high risk of central obesity owing to unhealthy lifestyles, making them prone to development of metabolic syndrome which leads to infertility, polycystic ovary syndrome (PCOS), insulin resistance, and type 2 diabetes (T2D). Premenopausal women with (n=30) and without (n=30) central obesity were studied. Metabolic risk factors and circulatory adipokines were measured. Insulin resistance was calculated by homeostasis model assessment (HOMA-IR). Adipokines' gene polymorphisms were studied by polymerase chain reaction and mRNA expression of leptin, adiponectin, resistin, and interleukin-6 (IL-6). Tumour necrosis factor-α (TNF-α), acylation stimulating protein (ASP) receptor gene (C5L2) were done by real time-polymerase chain reaction in visceral (VAT) and subcutaneous (SAT) adipose tissues was also obtained.Significant high circulating leptin, IL-6, TNF-α, resistin and their VAT mRNA expression and significant low circulating adiponectin and VAT mRNA expression were found in women with metabolic syndrome, irrespective of their menopausal status. Carriers of mutant genotype of TNF-α 308 AA, IL-6 174 CC, resistin 420 GG, leptin 2549 AA, adiponectin 276 TT and C5L2 698 CT had significant association with metabolic syndrome. Conclusively changes in fat distribution modulate the secretion profile of adipokines, therefore elevated circulating leptin, IL-6, TNF-α, ASP, resistin, and low adiponectin may serve as surrogate markers for metabolic syndrome and related morbidities in women with central obesity.
Effects of Dietary Conjugated Linoleic Acid and Selected Vegetable Oils or Vitamin E on Fatty Acid Composition of Hen Egg Yolks

Abstract The objective of this study was to produce eggs enriched with conjugated linoleic acid (CLA) and ameliorate their fatty acid profile using the appropriate combination of dietary CLA with or without vegetable oils (olive oil or rapeseed oil) and vitamin E. In Experiment 1, 25-week-old laying hens were randomly distributed into eight groups of nine. Birds were fed with a standard diet with four different levels of CLA (0.0, 0.5, 0.75, 1.0%) and vegetable oils (olive oil or rapeseed oil, both in the amount of 1.46%). In Experiment 2, hens were randomly distributed into 12 groups of nine. The same four levels of CLA with three doses of vitamin E (0, 150, 300 mg/kg of diet) were applied. In both experiments, eggs were collected twice (at 4 and 8 weeks) for fatty acid profiling using GCMS. The differences between treatment means were considered significant at P<0.05. CLA treatments significantly increased the content of CLA, saturated fatty acids (SFA), and significantly decreased the content of monounsaturated fatty acids (MUFA) in the egg yolk, whereas levels of polyunsaturated fatty acids (PUFA) were unaffected. The vegetable oils used did not prevent the negative effects of CLA effectively. Only after eight weeks of experiment 1 SFA levels were significantly lower, but MUFA levels were significantly higher in groups fed with rapeseed oil compared to groups fed with olive oil. In experiment 2, the addition of vitamin E to the hen diet did not have an essential influence on the lipid profile of egg yolks.
The role of Runx1 in genetic models of breast cancer

Given the recent discovery of RUNX1 somatic mutations in biopsies of breast cancer patients, the overall purpose of the present thesis consists of using different in vivo and ex vivo experimental systems in the attempt to answer two main questions: firstly, if the Runx1 gene plays any causative role in the context of breast cancer; and secondly, if its putative function is symptomatic of a tumour suppressor gene and/or of a pro-oncogene. By characterizing the effects of Runx1 deletion in two different breast cancer mouse models (i.e. the MMTV-PyMT and the Wnt/β-catenin-driven models of mammary tumourigenesis), this thesis provides the first in vivo evidence of a dualistic role played by the gene in the context of breast cancer. Runx1 would in fact appear to act as a tumour suppressor at early stages of the disease, whilst as a pro-oncogene at later stages of mammary tumourigenesis. To fully comprehend the significance of these major findings, the introduction will first provide a brief description on the RUNX family of genes, as well as on the state-of-the-art knowledge of RUNX1’s role in both mammary gland and breast cancer biology. As such, particular attention will then be given not only to the ontogeny, endocrine regulation and composition of the murine mammary gland, yet also to the high degree of heterogeneity, the putative “cell-of-origin(s)” and the different experimental models commonly used to study breast cancer. Through the aforementioned rationale, it is hoped that the introduction will serve as a platform which may hold the key for unveiling the controversial role played by RUNX1 in the context of breast cancer.
Single-Neuron Representations of Spatial Targets in Humans

The hippocampus and surrounding medial-temporal-lobe (MTL) structures are critical for both memory and spatial navigation, but we do not fully understand the neuronal representations used to support these behaviors. Much research has examined how the MTL neurally represents spatial information, such as with “place cells” that represent the current location or “head-direction cells” that code for the current heading. In addition to behaviors that require an animal to attend to the current spatial location, navigating to remote destinations is a common part of daily life. To examine the neural basis of these behaviors we recorded single-neuron activity from neurosurgical patients playing Treasure Hunt, a virtual-reality spatial-memory task. By analyzing how the activity of these neurons related to behavior in Treasure Hunt, we found that the firing rates of many MTL neurons during navigation significantly changed depending on the position of the current spatial target. In addition, we observed neurons whose firing rates during navigation were tuned to specific heading directions in the environment, and others whose activity changed depending on the timing within the trial. By showing that neurons in our task represent remote locations rather than the subject’s own position, our results suggest that the human MTL can represent remote spatial information according to task demands.
