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.

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.

Mental Illness and Youth-Onset Homelessness: A Retrospective Study among Adults Experiencing Homelessness (open access)

Mental Illness and Youth-Onset Homelessness: A Retrospective Study among Adults Experiencing Homelessness

This article retrospectively evaluating the association between the timing of homelessness onset (youth versus adult) and mental illness as a reason for homelessness among homeless adults living in homeless shelters and/or receiving services from homeless-serving agencies in Texas and Oklahoma. A better understanding of these relationships could inform needs for early interventions and/or better prepare agencies that serve at-risk youth to address precursors to youth homelessness.

Charge stabilization via electron exchange: excited charge separation in symmetric, central triphenylamine derived, dimethylaminophenyl–tetracyanobutadiene donor–acceptor conjugates (open access)

Charge stabilization via electron exchange: excited charge separation in symmetric, central triphenylamine derived, dimethylaminophenyl–tetracyanobutadiene donor–acceptor conjugates

This article hypothesizes and demonstrates a new mechanism to stabilize the charge separated states via the process of electron exchange among the different acceptor entities in multimodular donor–acceptor conjugates. This work constitutes the first example of stabilizing charge-separated states via the process of electron exchange.

Bayesian Time-Series Models in Single Case Experimental Designs: A Tutorial for Trauma Researchers

Article discusses the utility of SCED data for trauma research, provides recommendations for addressing challenges specific to SCED approaches, and introduces a tutorial for two Bayesian models—the Bayesian interrupted time-series (BITS) model and the Bayesian unknown change-point (BUCP) model—that can be used to analyze the typically small sample, autocorrelated, SCED data.

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.
