Infection mechanisms of grapevine powdery mildew (Oidium tuckeri): Comparative studies of the penetration process on artificial membranes and leaf epidermis
Creators: name: Heintz, Catherine
Publisher: name: VITIS - Journal of Grapevine Research
Year: 2015

description: In order to study host-pathogen interfaces and relationships between grapevine and powdery mildew, an infection mode! was established. The model consists of synthetic membranes(≥ 0.4 μm) floating on liquid substrates; the membrane representing the cuticle of the host plant. The preparation of membranes and methods to test their impermeability and elasticity are described. The best results are obtained with membranes consisting of methacrylate polymers. On membranes layered on various substrates germinating conidia and germtubes were observed with light and scanning electron microscope and compared to the natural infection process on leaf surfaces. On membranes germination and initial growth seem to be controlled by air humidity which depends on the osmotic value of the liquid substrate. As shown the infection pegs of Oidium tuckeri are able to perforate synthetic membranes which should be resistant to enzymes. This implies that under our experimental conditions penetration is a mechanical process. Participation of enzymes under natural conditions can, however, not be excluded.

description: Enrofloxacin, a widely used fluoroquinolone antibiotic, may be a cause of bacterial drug resistance and is forbidden in poultry. Consequently, a sensitive and rapid method is required for its determination. Aptamers, which are more stable and easily synthesized than antibodies, may serve as alternatives in the development of methods for rapid detection. Six single-strand DNA aptamers binding to enrofloxacin were selected by in vitro selection. Aptamer number 17 showed the highest affinity for enrofloxacin with a dissociation constant of 188 nM and the highest guanine concentration (35%), which was predicted to be crucial for strong affinity of the aptamer to enrofloxacin, and successfully distinguished enrofloxacin from its structure analogs. Using aptamer number 17, a novel chemiluminescent enzyme immunoassay associating with biotin-streptavidin was developed that allowed the determination of enrofloxacin to 2.26 ng/mL. Due to its capability to determine enrofloxacin in bovine milk, this newly selected aptamer may find broad application in food and environmental monitoring.

description: The traditional use of bamboo throughout South East Asia is very diverse: fences, scaffolding, kitchen equipment, furniture, mats, blinds, toothpicks, paper pulp… Some applications use bamboo cane as such, however the current tendency is also towards an unstructured use of bamboo in the form of fibers or chips or even ashes. From strips, a wide variety of boards and plywood are made. Panels from bamboo fibers compressed in the presence of an organic resin are also in development for earthquake-resistant structures of the building market. But in most cases, the bamboo is used for its structural properties, of bamboo cane itself or of particles or fibers from bamboo. Some works only focus on moisture absorption but they mainly concern the bamboo charcoal. Works on thermal insulation bamboo fibers are still rarer. This study focuses on the development and characterization of particle boards which will have the specificity to participate both in thermal insulation and control of humidity inside the building. The advantage is to obtain materials with low environmental impact and to reduce energy consumption due to the reduction of the moisture content. First of all, the conditions for producing fiberboards are studied to obtain panels without glue or using environmentally friendly adhesives. These panels are then characterized according to the criteria required for panels used in buildings (bending, swelling). Finally, their ability to absorb and desorb moisture and their thermal conductivity are investigated.

description: Bio-based insulation materials have been increasing in the construction market in Europe. However, there is a lack of reliable standardised test method to determine their resistance against moulds. Moreover, existing test methods do not take into account real hygrothermal conditions in use. This research project aimed to develop a laboratory test method to assess the resistance of bio-based insulation materials against moulds. The test method was applied to different bio-based insulation materials: wood fibre, loose fill cellulose, straw and hemp-flax. The materials were artificially contaminated with moulds. Based on a hygrothermal study on use classes, two different climatic conditions were tested: 26°C 95 % of relative humidity and 26°C 85 % of relative humidity. After four weeks of mould exposure, both a visual examination and a counting of cultivable fungal units were performed. It was clearly demonstrated that the quantitative analysis of mould growth was necessary to assess the resistance of bio-based insulation materials against moulds. Results from two different laboratories gave evidence that this test method was reliable whatever the tested bio-based material. It was shown that among 8 tested materials, 2 were resistant to moulds at 95% of relative humidity. In addition, 2 untreated bio-based insulation materials which were not resistant to moulds at 95 % of relative humidity were resistant to moulds at 85% of relative humidity, thus enhancing the suitability of bio-based materials for insulation. A proposal of a mould test taking into account realistic hygrothermal conditions was discussed.

description: Quinones are chemical compounds produced from the oxidation of phenols. Among the quinones, naphthoquinones stand out as potential antitumor agents. Bladder tumour is the tenth most diagnosed in the world. Based on this, using a urothelial carcinoma cell line (T24), two naphthoquinones had their cytotoxicity tested by the MTT colorimetric method and were submitted to assays of clonogenic survival, morphology, cell cycle, cell migration and species reactive oxygen. The results showed 8-methoxy-α-lapachone and lausone presented selectivity indexes (19.5 and 28.0, respectively) for T24 cells. Moreover, the two naphthoquinones reduced the cell viability, interfered with the process of cell migration, changed the cell cycle kinectics and induced the production of species reactive oxygen (ROS). Additionaly, 8-methoxy-α-lapachone altered the morphology of the cells. In conclusion, the studied naphthoquinones showed potential antiproliferative effects in bladder cancer cells, interfering in cellular processes, possibly through oxidative stress.

description: The renewable and less impacting materials are more and more involved with science research. The bio-based materials can replace the traditional ones in order to reduce greenhouse gases emission produced by the building sector. This article presents the moisture properties of new bio-based material called "straw lime concrete" and of “hemp lime concrete”, which is considered as the reference material. The tests are performed to establish the experimental measure of sorption isotherm, water vapor permeability and moisture buffer capacity, which is estimated from the moisture buffer value determined under equilibrium conditions. The results showed that hygric performance of the materials studied is particularly interesting and both exhibit an excellent moisture buffer capacity.

description: Construction is one of the most polluting sectors of industry, which is the reason why developing sustainable building materials is of world-wide interest. Earth is being increasingly studied as a building material because of its low environmental impact and its abilities to regulate indoor moisture and to improve building users’ comfort. However, very few studies deal with unfired earth bricks with plant aggregates incorporated into the earth matrix to lighten the material and improve some properties of the composite. In response to such issues, the Bioterra ANR project aims to develop and characterize bio-based earth composites. In this paper, the mechanical and thermal properties of earthen bricks with barley straw are investigated. The proportions of straw used in the present study were 3% and 6% by weight of the earth, which was made of fines from aggregate washing sludge (FWAS). The results showed that the addition of 3% and 6% of straw decreased the compressive strength by 20% and 5% respectively. Concerning thermal insulation, the thermal conductivity of the specimens with 6% of straw decreased by 75%.

description: NatuRALiMe (acronym standing for: “Naturally durable: Developing and testing the Resilience of innovative natural Additives for Lime-based conservation Mortars”) is a two-year project (2013- 2015) funded by the European Union's Seventh Framework Programme (FP7/2007-2013) and being developed at the University of Oxford (UK). The overall aim of this research project is to design suitable and durable mortars made with lime and natural additives (i.e. derivatives of the vegetable and animal world). Interest in studying and using these additives is clearly linked to the need to use sustainable building materials and adopt processes that entail reduced pollution, CO2 emissions and energy consumption. The first part of this project has been especially focused on the study of hemp-based mortars. Hemp is one of the 10 major primary plants grown as a source of bast fibres and hurds, used for various industrial purposes, such as: textiles, cordage, panelling, biofuel, paper, plastic composites and building materials. The use of hemp hurds in mortars involves important modifications to textural, physical-mechanical and hygrothermal properties compared to those of a typical mortar made with a limestone aggregate. This research project aims to investigate all these inter-related aspects to gain an exhaustive knowledge into this peculiar biomaterial. In particular, new durability tests that consider at the same time temperature and humidity changes, rainfall, salt attack and microbiological growth have been designed to study the resilience of hemp-based mortars under different climatic conditions. The research so far demonstrates the importance of bio-receptivity to hemp mortar durability, something that has not to our knowledge been taken adequately into consideration before. This paper introduces the research work undertaken so far on hemp-based mortars under the NatuRALiMe project, aiming to contribute to the knowledge and development of sustainable plant-based building materials.

description: Bio-based concretes are mixes of vegetal aggregates with a mineral binder. These new materials are used for buildings as coating, wall or roofing. They provide good properties to the constructions in terms of hygrometry, acoustic, thermic and lightness. Bio-based aggregates used in these new materials are very different from classical mineral aggregates used in concrete. Their intrinsic characteristics have strong impacts on bio-based concrete properties. There are no official standard methods to describe bio-based aggregates and so it appears as an important issue to develop this field. This study is focused on hemp aggregates, which is a material commonly used in bio-based concrete. It is about how to evaluate the size of these nonmineral particles. Mineral aggregates size is defined with a single measurement because they are assimilated as a sphere, with eventually a shape coefficient to characterize flattening. Biosourced aggregates have a more parallelepiped shape. Two methods already exist to characterize them and are frequently used: sieving and image analysis. This study proposes a new method based on the use of a videogranulometer device. This device is based on shadowgraph principle and makes a continuous measurement on particles. It enables to obtain the width and length of each particle simultaneously, as image analysis method, with a better efficiency. This article details the elaboration of this method of evaluation of aggregate size properties: the choices of the parameters and the adaptation of the device. Compared results between the three methods, the two usual ones and the videogranulometer one, show a good correlation between the videogranulometer method and the classic ones. As a conclusion, the method developed here has the best amount of analyzed aggregates time necessary ratio and describes as well each particle, offering a great representativeness of a hemp stock.

description: This study aimed to prove the prostate cancer chemopreventive activity of compounds isolated from CA. We evaluated these compounds using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and evaluated their NF-κB inhibitory activity and apoptosis-inducing activity using western blot analysis and flow cytometry, respectively. Their DNA methylation activity was also evaluated via a methylation-specific polymerase chain reaction in androgen-dependent (LNCaP) and androgen-independent (PC-3) prostate cancer cell lines. Camptothin B (1), cornusiin B (2), and cornusiin A (3), which were isolated in our previous work, relatively reduced the protein expression levels in PCa cells. Among them, cornusiin B (2) exhibited excellent NF-κB inhibitory activity. Also, concentration-dependently increased the unmethylated DNA content and decreased the methylated DNA content in both PC-3 and LNCaP cells. Therefore, cornusiin B (2), which was isolated from CA, has the potential to act as a chemopreventive agent for prostate cancer.

description: Three new stilbenoids, namely two rare plant-derived phenanthrenes denominated Cajananthrenes A and B (1, 2) and one bibenzyl named Cajanbenzyl (3), together with a diphenyl ether derivative designated Cajanether (4), as well as five other known compounds (5-9) were isolated from the ethanolic extract of the leaves of Cajanus cajan. Their structures were determined through extensive spectroscopic analysis including UV, IR, NMR (1D and 2D) and HRESIMS as well. A plausible biogenesis pathway was proposed for the biosynthesis of compounds 1-3. Compounds 1 and 2 displayed moderate anti-inflammatory activity as evident from the inhibitory effect on NO production in LPS-stimulated RAW 264.7 macrophages with IC50 values of 73.6 and 44.6 μM respectively.

description: Hemp is used as an aggregate in hemp concrete, which is mainly constituted of hemp, cement, lime and water. As hemp is known to have a good affinity to water, it is important to understand its water uptake capacities. NMR relaxometry measurement allowed us to follow the kinetics of imbibition of water in hemp. Our results show that imbibition develops progressively over three days, which is far more than we can expect for porous media, even with nanopores. Then, water transfers between the different phases of hemp concrete were followed by NMR measurements. Due to the very different values of the NMR relaxation times of water in hemp and in the binder, we were able to observe the transfer of water from hemp to binder during the first week of setting.

description: This work is part of a project aimed at developing a new biocomposite material that can be used for building thermal insulation purposes. It deals with the mechanical characterization of this material, which is mainly made of sunflower stem chips and of biomatrix derived from chitosan, the latter being used as binder between the chips. Indeed, panels made of this material must exhibit minimum mechanical properties to be able to sustain various mechanical loads such as dead weight or local stress peaks due to mounting on walls. The goal is to investigate experimentally the link between the macroscopic response of the panels and phenomena that occur at the scale of the constituents, namely the bark and pith chips. The grid method, which is one of the full-field measurement systems employed in experimental mechanics to measure displacement and strain fields, is employed because of the very heterogeneous nature of this material. Heterogeneity is due to both the contrast in rigidity between bark and pith and to the presence of voids within the material. Because of the voids and the pith, a specific marking for the specimen surface under investigation has been developed. Compression tests performed on small briquettes made of this material provides useful information on the local response of the constituents. This also helps establishing a link with the global response of the tested briquettes. Typical experimental results will be shown and analysed during the presentation.

description: The durability of timber structures can be affected by the isolated or combined actions of loading, moisture content, temperature, biological activity, etc. This work focuses on the optimal design of new timber structures subjected to deterioration. Since the deterioration processes and the structural behavior of timber structures are complex, nowadays the deterioration models are not able to account for all influencing factors. Consequently, this study is based on an empirical model that was derived based in-lab experimental studies for the decay growth of brown rot in pine sapwood under variant climate conditions. Such a model is divided into two processes: (i) activation process and (ii) mass loss process. On the other hand, there are significant uncertainties involved in the problem. The uncertainties inherent to materials properties, models and climate are considered throughout a time-dependent reliability based-design optimization (TD-RBDO) approach. The TD-RBDO aims to ensure a target reliability level during the operational life. This approach is applied to design optimization of a new timber component subjected to different French climates. The performance of the optimized solution is compared with a traditional cross-section designed according to the Eurocode 5 in terms of safety. The overall results indicate that an optimized solution ensures a target reliability level during the whole structural lifetime.

The data from the National Health and Nutrition Examination Survey for 2003–2008 were analyzed by regression models. SHS at home for children was associated with statistically significantly higher unadjusted levels of 2-hydroxynapthalane, 2-, 3-, and 9-hydroxyfluorene, 1-, 2-, and 3-hydroxyphenanthrene, and 1-hydroxypyrene. Also, SHS at home for adolescents was associated with statistically significantly higher unadjusted levels of 2- and 9-hydroxyfluorene, 2- and 3-hydroxyphenanthrene, and 1-hydroxypyrene. Further, SHS exposure at home was associated with (1) higher adjusted levels of 9-hydroxyfluorene for 6–12 years old (p < 0.01) and (2) lower adjusted levels of 1-hydroxynaphthalene for 12–19 years old (p < 0.01).

description: This study aimed to isolate and identify three prenylflavonoids (cannflavin A, B, and C) from Cannabis sativa leaves using different chromatographic techniques. The potential of the isolated compounds against SARS-CoV-2 was suggested through several in silico analysis. Structural similarity studies against nine co-crystallized ligands of SARS-CoV-2’s proteins indicated the similarities of the isolated cannflavins with the SARS-CoV-2 Papain-Like Protease (PLP) ligand, Y95. Then, flexible allignment study confirmed this similarity. Docking experiments showed successful binding of all cannflavins within the active pocket of PLP, with energies comparable to Y95. Among them, cannflavin A demonstrated the most similar binding mode, while cannflavin C exhibited the best energy. Molecular dynamics (MD) simulations and MM-GPSA confirmed the accurate binding of cannflavin A to the PLP. In silico ADMET studies indicated favourable drug-like properties for all three compounds, suggesting their potential as anti-SARS-CoV-2 agents. Further In vitro and In vivo investigations are necessary to validate these findings and establish their efficacy and safety profiles.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: Hemp concrete is a bio-based material generally made of lime-based binder and hemp shiv currently used for building envelop. This lightweight material shows a thermal conductivity about 100 mW/(m.K). On hygric point of view, hemp concrete is strongly hygroscopic, with high moisture transfer and storage capacities. These properties allow hemp concrete to moderate ambient relative humidity variations. It is an excellent hygric regulator with moisture buffer values globally higher than 2 g/(m².%RH).On mechanical point of view, hemp concrete is a non-load bearing material. It gains mechanical resistance over the first few weeks after manufacturing. These mechanical performances depend, among other factors, on the properties of components and on the mix proportioning. In order to improve the mechanical resistance of hemp concrete at early stage, this study investigates new formulations starting from reference formulation. The binder composition varies by increasing the substitution rate of lime-based binder for selected calcium sulfate-based binder. This binder leads to interesting hardening at early stage. The effect on mechanical performances at long term appears effective, without large influences on thermal and hygric properties (maximal variation about 20% and 15%). Effective proportioning tool is then available.

description: Hemp-lime concrete (HLC) is a bio-based material which is currently undergoing a growing development. HLC is a low embodied energy material and an excellent hygrothermal regulator. Its thermal, hygric and mechanical properties are well known, and its capacity to reduce energy needs and to improve hygrothermal comfort was demonstrated across many laboratory and numerical studies. However, there are few works about its hygrothermal performance in real climatic conditions on the scale of a building. A French HLC individual dwelling-house was monitored during 2 years. Its envelope is made of 300mm thick sprayed HLC associated with a timber frame structure. Air temperature and relative humidity of each room were measured. Temperature and relative humidity of North and West facing walls were measured at their surfaces and inside the walls at two different depths. Besides heat flux is measured at the inside surface of the north wall. This paper presents the results collected in the framework of a field study to determine the transient hygrothermal behavior of HLC in real conditions. In-situ monitoring of walls temperatures shows the ability of HLC to almost completely dampen variations of external temperature with 11 hours time-shift. The evolution of indoor relative humidity confirms that HLC has an excellent moisture buffer performance. The analysis of the hygrothermal behavior of a wall is achieved by comparing measurements and numerical simulations results. In this study, two simulation tools are used and compared. The first tool is based on the well-known Wufi software and doesn’t take into account the hysteresis effect. In the second simulation tool, numerical simulations are performed with a hysteresis model implemented in a heat and moisture transfer model. Comparisons between numerical and experimental results highlight some influent parameters in the simulation of the hygrothermal response of a HLC wall in real climatic conditions.

description: This paper investigates the effect of testing variables including curing conditions (65% vs>95% RH), time of demoulding and specimen geometry (cylinder vs cube) on the compressive strength of hemp concrete. It studies hydration in the concrete’s microstructure and measures compressive strength development at intervals between 1 day and 1 month. Moulding time and curing conditions influence drying and therefore may impact binder hydration and consequently strength evolution. Specimen geometry may affect drying and can also determine how strain builds up in the concrete and thus when failure occurs. The paper concludes that curing hemplime concrete with hydraulic content (50%CL90: 50%CEMII) at high RH (>95%) lowers compressive strength (65.4% drop at 10 weeks). It is unclear why this happens, as the presence of water vapour during curing at high RH should enhance hydration and consequently increase strength. It was also found that delaying specimen demoulding increases compressive strength of the CL90:CEMII concrete (22.9% increase at 10 weeks), probably due to the presence of moisture for longer enhancing hydration. The NHL3.5 concrete shows the same trends although the results are not statistically significant probably due to lack of sensitivity of the measuring instrument at low strength values. The specimen geometry does not significantly impact the ultimate compressive strength of hemp-lime concrete however, it affects behaviour in compression. Initially, cylinders and cubes deform on load application up to a similar yield point. However, following this yield point, the cylinders fracture showing a more brittle behaviour while the cubes keep crushing to finally experience an additional stiffness produced by mechanical bridges being formed between opposing cell walls.

description: Emissions of building materials might have negative impact on human health and well-being. In the EU-funded research project H-House more than 30 natural materials (earthen dry boards and plasters, bio-based insulation materials made of wood, flax, reed, straw, etc.) used for renovation and refurbishment were tested regarding emissions of VOC, formaldehyde and radon. Different to ordinary emission tests on single materials this study focuses on the emissions from complete wall assemblies. Therefore, specially designed test chambers were used allowing the compounds to release only from the surface of the material facing indoors. The testing parameters were chosen in order to simulate model room conditions. The emission results were finally evaluated using the AgBB evaluation scheme, a procedure currently applied for the approval of flooring materials in Germany.

description: Σκοπός του βιβλίου δεν είναι να διδάξει μία γλώσσα προγραμματισμού, αλλά να απευθυνθεί στον πρωτοετή φοιτητή ή σε οποιονδήποτε αναγνώστη κάνει τα πρώτα του βήματα στον προγραμματισμό, χωρίς να απαιτείται να έχει την παραμικρή εμπειρία ή γνώση στο θέμα. Έτσι επιχειρεί να εισάγει τον αναγνώστη στη φιλοσοφία του διαδικασιακού προγραμματισμού και να του δείξει τον τρόπο με τον οποίο πρέπει να σκεφτεί ξεκινώντας από ένα συγκεκριμένο πρόβλημα που έχει να λύσει μέχρι να το κάνει κώδικα που μπορεί να μεταφραστεί και να εκτελεστεί από έναν υπολογιστή.

Για να μπορέσει να χρησιμοποιήσει στην πράξη ο αναγνώστης αυτά που μαθαίνει στη θεωρία, αλλά και για να μπορέσει να αποκτήσει εμπειρία και να εξασκηθεί στον προγραμματισμό, χρησιμοποιείται η γλώσσα προγραμματισμού Python σαν θεμέλιο πάνω στο οποίο κτίζουμε. Η Python είναι απλή και κατανοητή γλώσσα προγραμματισμού μα με αυξημένη δυναμική και προσφέρεται για κάτι τέτοιο. Περιγράφεται στο βιβλίο στο βαθμό που αυτό είναι αναγκαίο ώστε να μπορέσει να γίνει μία γλώσσα έκφρασης για τον συγγραφέα και στη συνέχεια και για τον αναγνώστη και να μπορέσει να του προσφέρει ένα εργαλείο για την εξάσκησή του μέσα από το οποίο θα εμπεδώσει την λογική του προγραμματισμού.

Η γλώσσα Python είναι σήμερα πολύ δημοφιλής και κερδίζει καθημερινά νέους φίλους. Επιτρέπει την ανάπτυξη προγραμμάτων γράφοντας πολύ λίγες γραμμές κώδικα. Χρησιμοποιείται για την ανάπτυξη εφαρμογών τόσο για ερευνητικούς όσο και για εμπορικούς σκοπούς, ενώ υποστηρίζεται από μεγάλο αριθμό πλούσιων βιβλιοθηκών. Υποστηρίζει επίσης αντικειμενοστρεφή προγραμματισμό, κάτι που επιτρέπει να αφιερώσει κανείς ένα εισαγωγικό κεφάλαιο σε αυτό το βιβλίο ώστε να έχει ο αναγνώστης μία πρώτη επαφή και με τη φιλοσοφία αυτή.

Το βιβλίο ξεκινάει από εύκολα προβλήματα και σιγά σιγά αυξάνεται η δυσκολία τους. Έτσι, σε προχωρημένα κεφάλαια, ο αναγνώστης αντιμετωπίζει θέματα αναζήτησης, ταξινόμησης, μαθηματικά προβλήματα ή ακόμα και κατασκευάζει απλά παιχνίδια όπως η κρεμάλα και ο ναρκαλιευτής.
