BACKGROUND: Development of eukaryotic organisms is controlled by transcription factors that trigger specific and global changes in gene expression programs. In plants, MADS-domain transcription factors act as master regulators...
Uncovering correlated variability in epigenomic datasets using the Karhunen-Loeve transform.
BACKGROUND: Larger variation exists in epigenomes than in genomes, as a single genome shapes the identity of multiple cell types. With the advent of next-generation sequencing, one of the key problems in computational...
Robust and reusable supported palladium catalysts for cross-coupling reactions in flow
Two novel polymer encapsulated silica supported palladium catalysts have been prepared and shown to be highly active, robust and recyclable catalysts for Heck and Suzuki–Miyaura cross coupling reactions under continuous flow...
Multifunctional Role of Magnetic Nanoparticles in Efficient Microalgae Separation and Catalytic Hydrothermal Liquefaction
In this work, the efficiency of extracting algae from culture medium using magnetic nanoparticles (MNPs), converting the algal/particle slurry to biocrude using hydrothermal liquefaction (HTL), and successfully recycling the...
Kinetics of CO<sub>2</sub> Hydrogenation to Hydrocarbons over Iron-Silica Catalysts
The conversion of CO2 to hydrocarbons is increasingly seen as a potential alternative source of fuel and chemicals, while at the same time contributing to addressing global warming effects. An understanding of...
Ruthenium-catalyzed <i>O</i>- to S-alkyl migration
A practical ruthenium-catalyzed O- to S-alkyl migration affords structurally diverse thiooxazolidinones in excellent yields. Our studies suggest this catalytic transformation proceeds through a pseudoreversible radical...

Efficiency of Environmental Protection Expenditures in EU Countries
Environmental protection policy is a widely discussed issue in scientific works. However, special attention should be also paid to the effectiveness of expenditures on environmental protection, and this is the main goal...

Rhodri E. Owen, Pawel Plucinski, Davide Mattia, Laura Torrente-Murciano, Valeska P. Ting, Matthew Jones
Dec 01, 2016
This study of the effect of support of Co-Na-Mo based catalysts on the direct hydrogenation of CO2 into hydrocarbons (HC) provides guidelines for the design of catalysts for CO2 conversion. We...

Phloem development
Phloem, as a major tissue mediating long-distance communication, has been an object of extensive research ever since its structure was first reported in 1837. Functional phloem consists of sieve elements (SEs) and companion...

High CO<sub>2 </sub>and CO conversion to hydrocarbons using bridged Fe nanoparticles on carbon nanotubes
Justin O'Byrne, Rhodri Owen, Daniel Minett, Sofia I Pascu, Pawel K Plucinski, Matthew D Jones, Davide Mattia
May 01, 2013
An aerosol assisted chemical vapour deposition method has been used to generate a carbon nanotube (CNT) based iron catalyst for the conversion of CO and CO2 to longer chain hydrocarbons. The same formed iron nanoparticles (NPs)...
Divergence of regulatory networks governed by the orthologous transcription factors FLC and PEP1 in Brassicaceae species.
Julieta L Mateos, Vicky Tilmes, Pedro Madrigal, Edouard Severing, René Richter, Colin WM Rijkenberg, Paweł Krajewski, George Coupland
Jun 19, 2020
Genome-wide landscapes of transcription factor (TF) binding sites (BSs) diverge during evolution, conferring species-specific transcriptional patterns. The rate of divergence varies in different metazoan lineages but has not...

Maternal overnutrition has been associated with increased susceptibility to develop obesity and neurological disorders later in life. Most epidemiological as well as experimental studies have focused on the metabolic...
The self-organization of plant microtubules inside the cell volume yields their cortical localization, stable alignment, and sensitivity to external cues.
Vincent Mirabet, Pawel Krupinski, Olivier Hamant, Elliot M Meyerowitz, Henrik Jönsson, Arezki Boudaoud
Apr 27, 2018
Many cell functions rely on the ability of microtubules to self-organize as complex networks. In plants, cortical microtubules are essential to determine cell shape as they guide the deposition of cellulose microfibrils, and...
