Abstract:
Background Two automatable in-house protocols for high-troughput RNA extraction from nasopharyngeal swabs for SARS-CoV-2 detection have been evaluated. Methods One hundred forty one SARS-CoV-2 positive samples were collected during a period of 10-days. In-house protocols were based on extraction with magnetic beads and designed to be used with either the Opentrons OT-2 (OT-2in-house) liquid handling robot or the MagMAXTM Express-96 system (MMin-house). Both protocols were tested in parallel with a commercial kit that uses the MagMAXTM system (MMkit). Nucleic acid extraction efficiencies were calculated from a SARS-CoV-2 DNA positive control. Results No significant differences were found between both in-house protocols and the commercial kit in their performance to detect positive samples. The MMkit was the most efficient although the MMin-house presented, in average, lower Cts than the other two. In-house protocols allowed to save between 350€ and 400€ for every 96 extracted samples compared to the commercial kit. Conclusion The protocols described harness the use of easily available reagents and an open-source liquid handling system and are suitable for SARS-CoV-2 detection in high throughput facilities.

Abstract:
Abstract Abstract 982 Mounting evidence on the role of tumour microenvironment in supporting the growth and survival of multiple myeloma (MM) and other tumour cells makes testing of potential drug treatments in vitro in this setting almost obligatory. It is becoming evident that effective therapeutic approaches against MM must target not only MM cell viability but also the pro-survival support of the tumour cellular and non-cellular stroma. Recently developed strategies recreate the myeloma tumour microenvironment in vitro allowing for detection of myeloma cell proliferation or distribution in bone marrow compartments using cell imaging. However, there is a need for high troughput self-contained co-culture technology to facilitate differentiation in the behaviour of myeloma plasma cells from the accessory cells in the tumour microenvironment. Herein, we validate a high throughput in vitro co-culture experimental platform to analyse and measure simultaneously the effect of therapeutic agents on MM cells and the tumour stroma in co-culture. We have generated eGFP-MM cell lines (eGFP-MM1.S, eGFP-MM1.R, eGFP-U266) by lentiviral infection and clonal selection by limiting dilution and validated that eGFP-expressing cells maintain the properties of the parental cell lines. The same methodology was used to generate eGFP-K562 (myeloid malignancies), eGFP- PC3, eGFP-DU145 (both prostate cancer cell lines) and eGFP-HT29 (colon cancer cell line). We show that growth of eGFP-expressing cells can be estimated using fluorimetry (lexcitation 395/475; l emission 509) or image-based analysis in the presence of other BM cells in co-culture. The use of eGFP-MM cells also allows flow cytometry analysis of cell cycle profile and apoptosis with no significant cellular contamination from co-cultured cells such as fibroblasts, osteoclasts or stromal cells derived from bone marrow aspirates of MM patients. Additionally, we have generated and validated mCherry-expressing HS5 fibroblast cell lines as HS5 cells are commonly used to study the support by fibroblasts of proliferation and viability of MM cells. Proliferation of mCherry-HS5 cells can be evaluated using fluorimetry (l excitation 584; l emission 607) or image-based analysis in the presence of various tumour cells of haematological origin and solid tumours. The disadvantage of the MTT assay is that it is impossible to distinguish the signal of specific cell types in co-culture whereas the use of fluorescent cell lines allows us to discriminate these signals. We found that proliferation of stromal cells is differentially stimulated by different tumour cells and drug treatments. Additionally, the spatial organisation of stromal cells is also specifically altered depending on the type of tumour. These results suggest that tumour cells generate distinct signals that can affect stromal cells specifically resulting in explicit therapeutic requirements to prevent the support of the tumour microenvironment. We also found that when MM cells were seeded at low densitiy, stromal cells promote MM cell proliferation and resistance to therapeutic agents. However, when MM cells were plated at high densities and can easily enter exponential growth, tumour cells can grow independently of the presence of the stroma. However both at high and low densities, stromal cells abrogated either partially or completely the pro-apoptotic effect of therapeutic drugs. The use of eGFP-MM and mCherry HS5 cells enables application of laboratory techniques to effectively distinguish and screen the effects of drugs on the biology of myeloma cells and stromal cells in a co-culture setting that reproduces more accurately some key aspects of the tumour microenvironment. We propose the use of this experimental platform to evaluate therapeutic drugs against MM as well as other malignancies. Disclosures: No relevant conflicts of interest to declare.

Abstract:
Abstract The Slender-billed Curlew (Numenius tenuirostris) is a worldwide endangered bird species on the brink of extintion. For the last time it nested in Siberia, Russia. It flew trought Europe regulary in the 19th century. Because its records are unrepeatable, each date has a high scientific value. This article describes the historical record probably of the Czech Republic, probably in north-eastern Moravia in the environment of Místek in Lachia, probably between the years 1884 and 1897. This record might come from the collection of J. Bednař from the school in Místek (now Frýdek-Místek). These indirect data are provable and it is not possible to agree with the conclusion of the Czech Faunistic Committee which considers the location and date as unknown.

Abstract:
This study investigates the effects of science learning model reconstruction based on student needs, in order to generate more operational standards and teaching materials. The conceptual understanding through virtual laboratory appears minimal, based on the analysis addressing the demands of junior high school students in several locations in Papua. Hence, there is a necessity to reform the learning structure through the utilization of physics education technology (PhET). Furthermore, the model was reconstructed by the Model Education of Reconstruction with fundamental principles, including an analysis of the education needs based on PhET-Problem solving, to compose context describing energy materials and its changes. Expert validation on the accuracy of illustrations, drawings, tasks, exercises, and questions, indicates the model is eligible. The participants are 60 students control and experiment group for junior high school public 11 Jayapura. The results showed the science learning model has demonstrated increased virtual experiment abilities and conceptual understanding trought pretest and postest based N-Gain. Analysis of data based normality test and independent test (T-test), meanwhile, there is a significant differences between experimental and control group. Outcome of students' responses for a separate learning model reflected positive.

Abstract:
Cocoa (Theobroma cacao L.) like most tropical trees is recalcitrant in tissue culture. Somatic embryogenesis is generally efficient micropropagation technique to multiply elite material. However, Somatic embryogenesis in cocoa is difficult and this species is considered as recalcitrant. One of the factors often considered as a component of in vitro recalsitrance is a high phenolic content and oxidation of these compounds. In cocoa tissue culture accumulate large amounts of poliphenolics compounds which probably impair further development. This study was conducted to investigate the composition of phenolic compounds in cocoa flower and leaves, and their changes troughout the somatic embryogenesis process. Calli were induced in cacao floral and leaves explants on a half-strenght Murashige and Skoog medium containing 30 g/L Glucose and combination of 2,4 dichlorophenoxyacetic acid (2,4 D) with kinetin (kin). Total polyphenol content was observed on Sulawesi 1 cocoa clone. Embryogenic and non-embryogenic callus were also compared. The percentage of callus production from flower tissue is 85%, percentage of embryogenic callus 40 %, although the percentage of somatic embryo production from embryogenic callus callus is 70%. The conservation of callus into somatic embryos followed by decline in phenol content and an increase in peroxidase. The synthesis kinetics for these compounds in calli, under different somatic embryogenesis conditions, revealed a higher concentration under non-embryogenic conditions. So that, phenolic compound can influence the production of calli and an absence the phenolic compound can enhance production of somatic embryo.Kata kunci: Theobroma cacao L., polifenol, embrio somatik, kalus, flavonoid, katekin, in vitro recalcitance

Abstract:
Error-correcting codes are strongly adopted in almost every modern digital communication and storage system, such as wireless communications, optical communications, Flash memories, computer hard drives, sensor networks, and deep-space probes. New and emerging applications demand codes with better error-correcting capability. On the other hand, the design and implementation of those high-gain error-correcting codes pose many challenges. They usually involve complex mathematical computations, and mapping them directly to hardware often leads to very high complexity. This work aims to focus on Polar codes, which are a recent class of channel codes with the proven ability to reduce decoding error probability arbitrarily small as the block-length is increased, provided that the code rate is less than the capacity of the channel. This property and the recursive code-construction of this algorithms attracted wide interest from the communications community. Hardware architectures with reduced complexity can efficiently implement a polar codes decoder using either successive cancellation approximation or belief propagation algorithms. The latter offers higher throughput at high signal-to-noise ratio thanks to the inherently parallel decision-making capability of such decoder type. A new analysis on belief propagation scheduling algorithms for polar codes and on interconnection structure of the decoding trellis not covered in literature is also presented. It allowed to achieve an hardware implementation that increase the maximum information throughput under belief propagation decoding while also minimizing the implementation complexity.

Full text
Abstract:
Les zéolithes sont largement utilisées en catalyse. Un enjeu majeur est d'obtenir des cristaux nanométriques qui offrent des perspectives prometteuses dans la conception de catalyseurs acides plus actifs et plus sélectifs, notamment pour les procédés de conversion des coupes lourdes pétrolières. L'obtention de ces nano-cristaux peut résulter de l'utilisation d'inhibiteurs de croissance. Cette thèse s'est attachée à identifier deux familles de composés organiques limitant la croissance des cristaux. Pour la première, l'inhibition est envisagée par adsorption de composés organiques (polycations, acides aminés...) sur la surface des cristaux en formation. Cette étude a été réalisée en suivant une méthodologie d'expérimentation à haut-débit et a conduit à des cristaux de zéolithe Y (FAU) de 300 nm par l'ajout de L-lysine. La seconde famille est dérivée de l’approche de l’équipe de Ryoo et consiste en l’utilisation de composés bifonctionnels comportant une fonction structurante et une fonction inhibitrice de croissance. Cette étude a démarré par la synthèse de zéolithe MFI. La modélisation moléculaire a permis d'identifier un mono-ammonium alkylé favorisant la formation de nanofeuillets de zéolithe ZSM-5 d'épaisseur voisine de 2 nm. L'étude cinétique a révélé par ailleurs que cette zéolithe est synthétisée à partir d’un polysilicate lamellaire formé in situ. Cette stratégie d'identification, couplée à une méthodologie d'expérimentation à haut débit, a alors été appliquée à la synthèse des zéolithes EMC-1 (FAU) et EMC-2 (EMT), et a conduit à l'élaboration de nouveaux agents structurants et composés bi-fonctionnels
Zeolites are widely used in catalysis. One of today’s major challenges is to obtain nanometer-sized crystals, offering promising prospects for the design of more active and more selective acid catalysts, in particular for heavy oil conversion processes. Zeolite nanocrystals can be obtained by using growth inhibitors. This thesis focused on the identification of two families of organic compounds limiting the crystals growth. For the first one, the growth inhibition is favored by the adsorption of organic compounds (polycations, amino acids…) on the surface of growing crystals. This study was conducted using a high-throughput experiment methodology and led to zeolite Y (FAU) crystals of 300 nm by the addition of L-lysine. The second family is derived from Ryoo’s team approach and consists of the use of bifunctional compounds including one structure-directing function and one growth-inhibiting function. This study started with the synthesis of MFI zeolite. The molecular modelling allowed identifying an alkyl mono-ammonium directing the formation of 2 nm-thick nanosheets of zeolite ZSM-5. The kinetic study revealed that this zeolite is synthesized from a lamellar polysilicate formed in situ. This identification strategy, coupled to a high-troughput experiment methodology, was applied to the synthesis of zeolites EMC-1 (FAU) and EMC-2 (EMT) and conducted to the elaboration of new structure-directing agents and their bifunctional counterparts

Full text
Abstract:
Le poisson Astyanax mexicanus est un modèle particulièrement intéressant pour l'étude de l'évolution. En effet, dans cette espèce de poissons d'eau douce, il existe des populations vivant de façon pérenne dans des grottes. Dans cet environnement, l'obscurité est totale et permanente et les ressources en nourriture souvent faibles. Les poissons cavernicoles se sont adaptés à la vie souterraine et ils présentent de nombreuses modifications phénotypiques comme la dépigmentation, la perte des yeux, l’augmentation du nombre et de la taille d’organes sensoriels non-visuels et plusieurs changements du comportement. Un des problèmes majeurs est de savoir si ces modifications phénotypiques sont dues à des mutations préexistantes à la colonisation de l'environnement cavernicole ou si elles sont apparues après. Pour répondre à cette question, connaître l'âge des populations est un facteur important car dans une population récente, il n'y aura probablement pas eu suffisamment de temps pour l'apparition de beaucoup de mutations et leur fixation. L'objet de cette thèse est donc l'estimation de l'âge d'une population, celle de la grotte Pachón qui est souvent considérée comme étant une des plus anciennes et une des plus isolées. Au cours de ces travaux de thèse, nous avons développé une nouvelle méthode de datation qui repose d’une part sur la caractérisation du polymorphisme nucléotidique à l’intérieur de chaque population et entre populations, et d’autre part la comparaison de ces données avec des simulations de l’évolution du polymorphisme. Les résultats obtenus, ainsi que la réanalyse de données sur le polymorphisme d’haplotypes mitochondriaux et de loci microsatellites précédemment publiées, suggèrent que les populations cavernicoles seraient bien plus récentes qu’habituellement indiqué dans la littérature (quelques milliers d’années, et non plusieurs centaines de milliers d’années). Les conséquences d’un tempo rapide d’évolution sur le mode d’évolution de ces poissons cavernicoles ont aussi été présentées
The fish Astyanax mexicanus is a particularly suitable model for evolutionary biology studies. Indeed, in this species there are several subterranean populations which live in the total and permanent darkness of cave. These cavefish are well adapted to the life in this inhospitable environment and they show several differences with their surface conspecific such as depigmentation, eye loss and behavioral changes. A major unresolved issue is about the relative role of surface fish standing genetic variation and de novo mutations appeared in cavefish populations after their settlement in caves in their phenotypic evolution. In order to examine this issue, accurate estimations of population ages are very important because many new mutations cannot appear and fix in a recent population. In this thesis we aimed to estimate the age of the Pachón cave population which is considered as one of the oldest and most isolated populations. We developed a new method which is based on measures of the distribution of single nucleotide polymorphism within each population and between populations. Our results, as well as reanalyses of published data about mitochondrial haplotypes and microsatellite loci polymorphism suggest that cavefish populations are much more recent than previously thought (several thousand years and not several hundred thousand years). The consequences of a fast tempo of evolution on the mode of evolution of cavefish are also discussed
