Research data of an article: "Application of high resolution melting assay (HMR) to study temperature dependent infraspecific competition in an patho…
2017
Studies on species’ responses to climate change have focused largely on the direct effect of abiotic factors and in particular temperature, neglecting the effects of biotic interactions in determining the outcome of climate change projections. Many microbes rely on strong interference competition; hence the fitness of many pathogenic bacteria could be a function of both their growth properties and intraspecific competition. However, due to technical challenges in distinguishing and tracking individual strains, experimental evidence on intraspecific competition has been limited so far. Here, we developed a robust application of the high-resolution melting (HRM) assay to study head-to-head co…

Effet du statut organique des sols pollués sur la dynamique et l'impact du cuivre sur les communautés microbiennes
2009
National audience; L’effet du statut organique des sols (SOS) sur l’impact du cuivre a été évalué par une approche en microcosmes et lysimètres d’un sol de vigne amendé en diverses matières organiques lors d’une expérience de terrain de long terme. Des microcosmes et des lysimètres du sol de vigne ont été contaminés à 240 mg Cu kg-1 et incubés à 23°C pendant 12 mois. La distribution et la dynamique du cuivre ont été caractérisées par fractionnement granulométrique et spéciation solide en extraction séquentielles et par spéciation liquide par mesure de concentration de cuivre échangeable total (ICP-AES), libre (électrode sélective) et biodisponible (biosensor). L’impact du cuivre sur les com…

Caractérisation moléculaire de l’évolution des communautés microbiennes de sols du dispositif EFELE sur la période 2012-2021 : impact de l'apport de …
2022
It is becoming increasingly difficult to feed the growing population and it is therefore important to doeverything possible to improve our agriculture. To do this, a device called "EFELE" was created in 2012 toobserve how the soil reacts over a period of 20 years. This is essential for cultivation and allows us to obtainvarious information, including bio-indicators. The years 2012 and 2021 will be treated in order to define theamount of DNA in the soil, the microbial balance, the richness and diversity of the soil. In order to study howagriculture could be improved, different trials have been established. One of them studies the effects of theinput of organic waste products (OWPs) from live…
Development of economic MeV-ion microbeam technology at Chiang Mai University
2017
Developing high technologies but in economic manners is necessary and also feasible for developing countries. At Chiang Mai University, Thailand, we have developed MeV-ion microbeam technology based on a 1.7-MV Tandetron tandem accelerator with our limited resources in a cost-effective manner. Instead of using expensive and technically complex electrostatic or magnetic quadrupole focusing lens systems, we have developed cheap MeV-ion microbeams using programmed L-shaped blade aperture and capillary techniques for MeV ion beam lithography or writing and mapping. The programmed L-shaped blade micro-aperture system consists of a pair of L-shaped movable aperture pieces which are controlled by …
Depletion of
2020
Child obesity constitutes a risk factor for developing insulin resistance which, if sustained, could lead to more severe conditions like type 2 diabetes (T2D) in adulthood. Our study identified previously unknown species whose depletion (Blautia luti and Blautia wexlerae) is associated with insulin resistance in obese individuals. Our results also indicate that these bacterial species might help to reduce inflammation causally linked to obesity-related complications. Childhood is considered a window of opportunity to tackle obesity. These new findings provide, therefore, valuable information for the future design of microbiota-based strategies for the early prevention of obesity-related com…
