Le professeur Dennis Salahub a fait d'importantes contributions dans plusieurs domaines scientifiques. Vraisemblablement, la moins connue de ces contributions est celle sur l'étude de la cinétique de l'expression des gènes dans les procaryotes qui a conduit à un modèle stochastique différé ... more
Nature Protocols 8, 2098 (2013). doi:10.1038/nprot.2013.138 Authors: Takuya Sato, Kumiko Katagiri, Yoshinobu Kubota & Takehiko Ogawa The in vitro propagation of mouse spermatogonial stem cells (SSCs) became possible in 2003; these cultured SSCs were named germ-line stem ... more
Utilisant des approches divergentes, on a réalisé des synthèses de nouveaux mésogènes en forme étoilée à base d'acide trimésique et des portions centrales portant des chaînes latérales symétriques se terminant par des groupes alcoxy. Les portions centrales et les chaînes latérales sont liée ... more
Genes involved in normal developmental processes attract attention as mediators of tumour progression as they facilitate migration of tumour cells. EMT (epithelial-mesenchymal transition), an essential part of embryonic development, tissue remodelling and wound repair, is crucial for tumou ... more
There are very few luminescence studies for rare earth borates with hydroxyl or crystalline water molecules, which were supposed to have a low luminescent efficiency because the vibrations of -OH or H2O may lead to the emission quench. We were motivated to study the luminescent properties o ... more
Cell surface glycans are a class of sophisticated biomolecules related to cancer development and progression, and their analysis is of great significance for early cancer diagnosis and treatment. In this paper, we proposed a fluorescence assay to evaluate glycan expression on living cancer ... more
We report a microfluidic approach for lithographically photo-patterning compartmentalized microparticles with any 2D-extruded shape, down to the cellular length scale (~10 microns). The prepolymer solution consists of a UV crosslinkable perfluorodecalin-in-water nanoemulsion stabilized by P ... more
This paper describes the generation of genetically engineered bioluminescent magnetotactic bacteria (BL-MTB) and their integration into a microfluidic analytical device to obtain a portable toxicity detection system. Magnetospirillum gryphiswaldense strain MSR-1 was bioengineered to constit ... more
A novel pH probe based on hemi-cyanine was synthesized, which displays extremely large Stokes shift (122 nm) and good photostability. The probe responds to basic pH (pKa 8.32) with colorimetric and fluorescence turn-on signal. Interestingly, probe has good cell membrane permeability and cou ... more
A binary mixture of Tb3+ and pyrocatechol violet (PV) forms a 1:1 Tb3+/PV complex that can be used in a dye displacement assay. Addition of dipicolinate (DPA) to the Tb3+/DPA complex simultaneously produces a PV color change from blue to yellow and luminescence emission from the newly forme ... more

Frequency-modulation atomic force microscopy (FM-AFM) was employed to reveal the structural properties of a rubrene single crystal immersed in an ionic liquid. We found large vacancies formed by the anisotropic dissolution of rubrene molecules. Molecular resolution imaging revealed that str ... more
The inhibitory action of PDCD4 in lipopolysaccharide/D-galactosamine-induced acute liver injury Laboratory Investigation 93, 1164 (October 2013). doi:10.1038/labinvest.2013.75 Authors: Xiaoyan Wang, Lining Zhang, Zengtao Wei, Xia Zhang, Qi Gao, Yanyan Ma, Xingli Liu, ... more
Adenosine A2B receptor-mediated VEGF induction promotes diabetic glomerulopathy Laboratory Investigation 93, 1164 (October 2013). doi:10.1038/labinvest.2013.56 Authors: Angel Cárdenas, Camilo Toledo, Carlos Oyarzún, Angélica Sepúlveda, Claudia Quezada, Elena Guillén- ... more

Gene silencing of EREG mediated by DNA methylation and histone modification in human gastric cancers Laboratory Investigation 93, 1165 (October 2013). doi:10.1038/labinvest.2013.100 Authors: Jiyeon Yun, Sang-Hyun Song, Jinah Park, Hwang-Phill Kim, Young-Kwang Yoon, K ... more
Pathophysiologic mechanisms in septic shock Laboratory Investigation advance online publication, September 23 2013. doi:10.1038/labinvest.2013.110 Authors: Elizabeth G King, Gustavo J Bauzá, Juan R Mella & Daniel G Remick more
Abstract The production of petroleum coke (petcoke) in the refineries is progressively peaking up because of the trend of processing heavy crudes and in turn, a renewed interest in delayed coking process. Therefore, an efficient, economical, and environmentally safe utilisation of petc ... more
The sol–gel method is employed for producing high surface area silica nanoparticles from a cheap precursor, that is water glass (sodium silicate). To design the experiments systematically, the response surface method (RSM) combined with the central composite design (CCD) approach is used ... more
Previous measurements have shown that freshly made wood pellets continued to emit flammable gases such as CO, H2 and CH4 during storage and handling. The research reported in this paper examines whether the concentration of these emitted gases and the available oxygen within enclosed woo ... more
Abstract Reactivity analysis of pulverised coal in O2/N2/CO2 environments was carried out using thermo‐gravimetric method. At all temperature ranges, coal combustion in O2/CO2 and O2/N2 environments using equivalent oxygen concentrations was almost similar. However, when oxygen concent ... more
Abstract This paper examines the pumping mechanisms generated by the Maxblend impeller. Simulation results obtained with the lattice Boltzmann method (LBM) are presented for Newtonian fluids (Re = 2–140) and strongly shear‐thinning fluids (Reg = 0.1–50) obeying the Carreau–Yasuda model ... more
Current microbial desalination cell (MDCs) performances are evaluated with chemical catalysts such as ferricyanide, platinum catalyzed air-cathodes or aerated cathodes. All of these methods improve power generation potential in MDCs, however, they are not preferable for large scale applicat ... more
DNA hybridization is an important step for a number of bioassays such as fluorescence in-situ hybridization, microarrays, as well as the NanoGene assay. The denaturation and fragmentation of genomic DNA are two critical pretreatments for DNA hybridization. However, no thorough and systemati ... more
Although the intense biogeochemical gradients present in riparian zones have the potential to affect mercury (Hg) cycling, Hg dynamics in riparian zones has received relatively little attention in the literature. Our study investigated groundwater filtered total mercury (THg) and methylmerc ... more
Metal and metalloid mobilization processes within seepage water are of major concern in a range of water reservoir systems. The mobilization process of arsenic and heavy metals within a dam and sediments of a drinking water reservoir was investigated. Principle component analysis (PCA) on t ... more
