Photostimulus-responsive Non-covalent Interactions in Polymers: A Review
No full textInternational audienceThis study reviews light-responsive polymers in various applications, including drug delivery, information storage, sensor, self-healing material, antibacterial or anti-fouling, and environmental applications. Light-responsive polymers are a new material type being developed for various medical, electronics, engineering, and environmental applications. The working principle of light-responsive materials is based on metal-ligand interactions or non-covalent interactions between polymer functional groups, metal ions, and other filler functional groups. Light irradiation causes physical and mechanical changes in drug delivery and antibacterial systems, which results in the materials releasing more drugs or antibacterial substances. When materials in information storage devices and sensors are exposed to light, they can change color or glow. This has been applied for data storage to reveal QR codes under UV light. Additionally, this review discusses the thermodynamic aspects and computer modeling of light-responsive materials to emphasize the importance and development of these materials. Finally, light-responsive polymer development for various applications is presented
Database establishment for the secondary fungal DNA barcode -Translational Elongation Factor 1α (TEF1α)
No full textWith new or emerging fungal infections, human/animal fungal pathogens are a growing threat worldwide. Current diagnostic tools are slow, non-specific at the species and subspecies levels, and require specific morphological expertise to accurately identify pathogens from pure cultures. DNA barcodes are easily amplified, universal, short species-specific DNA sequences, which enable rapid identification by comparison with a well-curated reference sequence collection. The primary fungal DNA barcode, ITS region, was introduced in 2012 and is now routinely used in diagnostic laboratories. However, the ITS region only accurately identifies around 75% of all medically relevant fungal species, which has prompted the development of a secondary barcode to increase the resolution power and suitability of DNA barcoding for fungal disease diagnostics. The translational elongation factor 1α (TEF1α) was selected in 2015 as a secondary fungal DNA barcode, but has not been implemented into practice, due to the absence of a reference database. Here, we have established a quality-controlled reference database for the secondary barcode which together with the ISHAM-ITS database, forms the “ISHAM BARCODE DATABASE”, available online at: http://its.mycologylab.org/. We encourage the mycology community for active contributions. The application of a dual DNA barcoding system enables accurate identification of all clinically important fungal pathogens.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

A synthesis of atmospheric mercury depletion event chemistry in the atmosphere and snow
No full textIt was discovered in 1995 that, during the spring time, unexpectedly low concentrations of gaseous elemental mercury (GEM) occurred in the Arctic air. This was surprising for a pollutant known to have a long residence time in the atmosphere; however conditions appeared to exist in the Arctic that promoted this depletion of mercury (Hg). This phenomenon is termed atmospheric mercury depletion events (AMDEs) and its discovery has revolutionized our understanding of the cycling of Hg in Polar Regions while stimulating a significant amount of research to understand its impact to this fragile ecosystem. Shortly after the discovery was made in Canada, AMDEs were confirmed to occur throughout the Arctic, sub-Artic and Antarctic coasts. It is now known that, through a series of photochemically initiated reactions involving halogens, GEM is converted to a more reactive species and is subsequently associated to particles in the air and/or deposited to the polar environment. AMDEs are a means by which Hg is transferred from the atmosphere to the environment that was previously unknown. In this article we review Hg research taken place in Polar Regions pertaining to AMDEs, the methods used to collect Hg in different environmental media, research results of the current understanding of AMDEs from field, laboratory and modeling work, how Hg cycles around the environment after AMDEs, gaps in our current knowledge and the future impacts that AMDEs may have on polar environments. The research presented has shown that while considerable improvements in methodology to measure Hg have been made but the main limitation remains knowing the speciation of Hg in the various media. The processes that drive AMDEs and how they occur are discussed. As well, the role that the snow pack and the sea ice play in the cycling of Hg is presented. It has been found that deposition of Hg from AMDEs occurs at marine coasts and not far inland and that a fraction of the deposited Hg does not remain in the same form in the snow. Kinetic studies undertaken have demonstrated that bromine is the major oxidant depleting Hg in the atmosphere. Modeling results demonstrate that there is a significant deposition of Hg to Polar Regions as a result of AMDEs. Models have also shown that Hg is readily transported to the Arctic from source regions, at times during springtime when this environment is actively transforming Hg from the atmosphere to the snow and ice surfaces. The presence of significant amounts of methyl Hg in snow in the Arctic surrounding AMDEs is important because this species is the link between the environment and impacts to wildlife and humans. Further, much work on methylation and demethylation processes has occurred but these processes are not yet fully understood. Recent changes in the climate and sea ice cover in Polar Regions are likely to have strong effects on the cycling of Hg in this environment; however more research is needed to understand Hg processes in order to formulate meaningful predictions of these changes.© Author(s) 2008.
