On Polish groups admitting non-essentially countable actions (open access)

On Polish groups admitting non-essentially countable actions

Article addresses the question whether every Polish group that is not locally compact admits a Borel action on a standard Borel space whose associated orbit equivalence relation is not essentially countable. The authors e answer this question positively for the class of all Polish groups that embed in the isometry group of a locally compact metric space.

Comparative Proteomics Analysis Reveals Unique Early Signaling Response of Saccharomyces cerevisiae to Oxidants with Different Mechanism of Action (open access)

Comparative Proteomics Analysis Reveals Unique Early Signaling Response of Saccharomyces cerevisiae to Oxidants with Different Mechanism of Action

This article uses a discovery driven comparative proteomics analysis to reveal unique early signaling response of the yeast Saccharomyces cerevisiae on the proteome level to oxidants with a different mechanism of action as early as 3 min after treatment with four oxidants, namely H₂O₂, cumene hydroperoxide (CHP), and menadione and diamide, when protein abundances were compared using label-free quantification relying on a high-resolution mass analyzer (Orbitrap).

RNaseH-mediated simultaneous piggyback knockdown of multiple genes in adult zebrafish (open access)

RNaseH-mediated simultaneous piggyback knockdown of multiple genes in adult zebrafish

This article tests if it is possible to piggyback more than one antisense deoxyoligonucleotide (dO) with one vivo morpholino (VMO). The authors previously developed a piggyback knockdown method that was used to knockdown genes in adult zebrafish. In this article, the authors develop a method to knockdown three genes at one time, and by increasing the concentration of VMO by twofold, could knockdown six genes simultaneously. These multiple gene knockdowns will not only increase the efficiency of the method in whole genome-wide knockdowns but will also be useful to study multifactorial disorders.

Chemical and Genetic Studies on the Formation of Pyrrolones During the Biosynthesis of Cytochalasans (open access)

Chemical and Genetic Studies on the Formation of Pyrrolones During the Biosynthesis of Cytochalasans

This article investigates the role of the highly conserved α,β-hydrolase enzymes PyiE and ORFZ during the biosynthesis of pyrichalasin H and the ACE1 metabolite, respectively, using gene knockout and complementation techniques. Taken together the results suggest that the α,β-hydrolase enzymes are essential for first ring cyclisation, but the precise nature of the intermediates remains to be determined.

Effect of increased embryonic temperature during developmental windows on survival, morphology and oxygen consumption of rainbow trout (Oncorhynchus mykiss) (open access)

Effect of increased embryonic temperature during developmental windows on survival, morphology and oxygen consumption of rainbow trout (Oncorhynchus mykiss)

This article applies a developmental 3-dimensional critical window experimental design for a vertebrate, using time, temperature, and phenotypic response (i.e., variables measured). To assess thermal effects on fish development, the authors examined trout hatchling phenotypes following rearing in constant temperatures (5, 10, 15 and 17.5 °C) and following exposure to increased temperature above 5 °C during specific developmental windows.
