Investigation and development of potato parentage analysis methods using multiplexed SSR fingerprinting
25 décembre 2014, HE CondorcetCARAHArticle scientifiqueParentage assessment in the potato (Solanum tuberosum L.), based on a reliable characterization of DNA varieties, can be a useful tool in validating pedigree information as well as for assigning potential parents to orphan varieties. The approach suggested in this study was to use the genetic profiles obtained on 577 cultivars using a set of 17 polymorphic simple sequence repeats (SSR) markers in ... -
Measurement of translesion synthesis by fluorescent capillary electrophoresis : 7,8-Dihydro-8-oxodeoxyguanosine bypass modulation by natural products
24 mai 2013, HE CondorcetArticle scientifiqueTranslesion synthesis (TLS) relies on a series of specialized DNA polymerases able to insert a base either correctly or incorrectly opposite a lesion on a DNA template strand during replication or post-repair synthesis. To measure the correct or mutagenic outcome of 7,8-dihydro-8-oxodeoxyguanosine (8-oxodG) bypass by TLS DNA polymerases, a capillary electrophoresis (CE) method with fluorescent label ... -
Use of self-organizing map to analyze images of fungi colonies grown from Triticum aestivum seeds disinfected by ozone treatment
16 octobre 2012, HE CondorcetCARAHArticle scientifiqueWe submitted to ozone treatment Triticum aestivum (common wheat) seeds severely contaminated by fungi. Fungi colonies developed when seeds were placed over malt agar medium in Petri dishes; Fusarium sp. and Alternaria sp. were identified. However, conventional colonies counting did not allow a clear assessment of the effect of ozone disinfection. We thus used self-organizing maps (SOMs) to perform ... -

Construction of a Novel Chimeric Dextransucrase Fused to the Carbohydrate-Binding Module CBM2a
28 septembre 2021, HE CondorcetArticle scientifiqueLactic acid bacteria (LAB) have the potential to produce homoexopolysaccharides (HoPS). Their health benefits and physicochemical properties have been the subject of extensive research. The HoPS functional properties are determined by molecular weight, the type of glycosidic link ages, degrees of branching and chemical composition. The dextransucrases (DSases) produce a kind of HoPS (dextrans), ... -
Cardiorespiratory responses during running and sport-specific exercises in handball players
mai 2009, HE CondorcetArticle scientifiqueTo determine whether a 4-a-side handball (HB) game is an appropriate aerobic stimulus to reach and potentially enhance maximal oxygen uptake (V˙O2max), and whether heart rate (HR) is a valid index of V˙O2 during a handball game. Nine skilled players (21.0 ± 2.9 yr) underwent a graded maximal aerobic test (GT) where V˙O2max and HR−V˙O2 relationship were determined. V˙O2, HR and blood lactate ([La]b) ... -
Accuracy of Medical Oxygen Flowmeters: A Multicentric Field Study
août 2014, HE CondorcetArticle scientifiqueThe accuracy of 476 oxygen flowmeters was investigated using a thermal mass flowmeter in eight hospitals in France and Belgium. Different oxygen flow rates (2 to 15 l/min) were evaluated at the patient’s bed. When the sample was considered as a whole, the accuracy of delivered flow was acceptable but precision was poor. The variability of the delivered flow between devices was greater when a low ... -
Effect of dietary nitrate supplementation on tolerance to supramaximal intensity intermittent exercise
29 mai 2015, HE CondorcetArticle scientifiqueDietary nitrate (NO3−) supplementation has been shown to increase exercise tolerance and improve oxidative efficiency during aerobic exercise in healthy subjects. We tested the hypothesis that a 3-day supplementation in beetroot juice (BJ) rich in NO3− would improve the tolerance to supramaximal intensity intermittent exercise consisting of 15-s exercise periods at 170% of the maximal aerobic power ... -
Effect of dietary nitrate supplementation on metabolic rate during rest and exercise in human: A systematic review and a meta-analysis
16 janvier 2016, HE CondorcetArticle scientifiqueBackground Recent randomized controlled trials have suggested that dietary nitrate (NO3-), found in beetroot and other vegetables, and inorganic NO3− salts decrease metabolic rate under resting and exercise conditions. Objective Our aim was therefore to determine from a systematic review and meta-analysis whether dietary NO3− supplementation significantly reduces metabolic rate, expressed as ... -
Bilateral Strength Deficit Is Not Neural in Origin; Rather Due to Dynamometer Mechanical Configuration
18 décembre 2015, HE CondorcetArticle scientifiqueDuring maximal contractions, the sum of forces exerted by homonymous muscles unilaterally is typically higher than the sum of forces exerted by the same muscles bilaterally. However, the underlying mechanism(s) of this phenomenon, which is known as the bilateral strength deficit, remain equivocal. One potential factor that has received minimal attention is the contribution of body adjustments to ... -

EEG dynamics and neural generators of psychological flow during one tightrope performance
24 juillet 2020, HE CondorcetArticle scientifiquePsychological “flow” emerges from a goal requiring action, and a match between skills and challenge. Using high-density electroencephalographic (EEG) recording, we quantified the neural generators characterizing psychological “flow” compared to a mindful “stress” state during a professional tightrope performance. Applying swLORETA based on self-reported mental states revealed the right superior ... -
EEG-based brain-computer interface for alpha speed control of a small robot using the MUSE headband
28 septembre 2020, HE CondorcetActe de conférence ou de colloqueNon-invasive BMI applications are increasingly used in different contexts ranging from industrial, clinical and gaming. After having tested the difference between a classical EEG recorder with electroconductive gel (ANT system) and the MUSE EEG headband, we studied the BCI performances of the later during the control of a small robot. We demonstrated that the participants were able to successfully ... -
Neural generators involved in visual cue processing in children with attention-deficit/hyperactivity disorder (ADHD)
10 novembre 2020, HE CondorcetArticle scientifiqueEvent-related potentials (ERP) studies report alterations in the ongoing visuo-attentional processes in children with attention deficit/hyperactivity disorder (ADHD). We hypothesized that the neural generators progressively recruited after a cue stimulus imply executive-related areas well before engagement in executive processing in children with ADHD compared to typically developed children (TDC) -

Plasma asymmetric dimethylarginine concentrations are not related to differences in maximal oxygen uptake in endurance trained and untrained men
22 novembre 2018, HE CondorcetArticle scientifiqueAsymmetric dimethylarginine (ADMA) is an endogenous inhibitor of nitric oxide (NO) synthesis that could limit oxygen (O2) delivery in the working skeletal muscles by altering endothelium‐dependent vasodilatation. Exercise capacity is associated with plasma ADMA concentrations in patients with cardiovascular diseases, but this issue has still not been investigated in healthy subjects. We aimed to ... -
A new formula for predicting the fraction of delivered oxygen during low-flow oxygen therapy
décembre 2018, HE CondorcetArticle scientifiqueDuring O2 therapy at low flow in patients who breathe spontaneously, the fraction of delivered O2 (FDO2) is unknown. In recent years, FDO2 prediction formulas have been proposed. However, they do not take into account the effect of inspiratory flow (V̇I) on the FDO2. The aim of this study was to validate a new FDO2 prediction formula, which takes into account the V̇I and compares it with other FDO2 ...
