Targeting hydroxycinnamoyl CoA: shikimate hydroxycinnamoyl transferase for lignin modification in Brachypodium distachyon (open access)

Targeting hydroxycinnamoyl CoA: shikimate hydroxycinnamoyl transferase for lignin modification in Brachypodium distachyon

This article conducts a study to evaluate the utility of Hydroxycinnamoyl CoA: shikimate hydroxycinnamoyl transferase (HCT) as a target for lignin modification in a species with an “incomplete” shikimate shunt. Results imply that this gene is a preferred target for biotechnological improvement of grasses for bioprocessing.

Anion-enhanced excited state charge separation in a spiro-locked N-heterocycle-fused push-pull zinc porphyrin (open access)

Anion-enhanced excited state charge separation in a spiro-locked N-heterocycle-fused push-pull zinc porphyrin

This article presents a new type of push–pull charge transfer complex, viz., a spiro-locked N-heterocycle-fused zinc porphyrin, ZnP-SQ, that is shown to undergo excited state charge separation, which is enhanced by axial F⁻ binding to the Zn center. Spectroelectrochemical studies are used to identify the spectra of charge separated states and charge separation upon photoexcitation of ZnP is established.

West Nile Virus risk and susceptibility in central California modeling dataset

The dataset was developed to support research intended to develop a spatially explicit model that explores environmental data related to the risk of exposure to West Nile Virus (WNV), and the susceptibility to WNV disease based on demographic data of the potentially affected population. The model was developed and then tested on census tracts in an identified hot spot of WNV in central California. The dataset contains (1) U.S. Census Bureau 2010 demographic data for 1,133 census tracks in the hotspot, and (2) and average mosquito habitat risk data for each of those census tracks.

Prioritizing riparian corridors for ecosystem restoration in urbanizing watersheds (open access)

Prioritizing riparian corridors for ecosystem restoration in urbanizing watersheds

This article explores restoration, rather than protection, being the basis for developing a watershed level strategy for improving water quality in urbanizing watersheds.This study uses a geographical information system (GIS) approach that utilizes riparian characteristics extracted from 40-meter wide corridors centered on streams and rivers. The model was applied to 90 sub-watersheds in the watershed of an important drinking water reservoir in north central Texas, USA.

Functional Porous Organic Polymers as Advanced Decontamination Materials for Water Purification (open access)

Functional Porous Organic Polymers as Advanced Decontamination Materials for Water Purification

Data management plan for the grant "Functional Porous Organic Polymers as Advanced Decontamination Materials for Water Purification." This project seeks to develop and deploy a new class of porous organic polymers which have high capacity and selectivity to rapidly remove heavy metal contaminants well below parts per million level standards set by the Environmental Protection Agency. The project will engineer porosity and surface chemistry of porous organic polymers to clean inorganic heavy metal contaminants from both surface water and wastewater. Porous organic polymers are robust, chemically and thermally stable, scalable, and modular, with very high surface area. The modularity of these polymers allows for a molecular-level tuning of the pore structure and surface chemistry that allows for engineered site-specificity of binding sites that target the heavy metal contaminants. Recent data shows these new materials offer a significant increase in capacity relative to benchmark materials, with a rapid removal of mercury and other heavy metal ions. This project will advance the concept by exploring rational design of these porous polymers with different topologies by customizing the monomer with various binding groups. The objectives of the project include design, synthesis, and characterization, followed by assessment of these materials to remove inorganic contaminants …

Caputo Fractional Derivative and Quantum-Like Coherence (open access)

Caputo Fractional Derivative and Quantum-Like Coherence

This article studies two forms of anomalous diffusions and discusses the joint use of these prescriptions, with a phenomenological method and a theoretical projection method, leading to two apparently different diffusion equations. The authors prove that the two diffusion equations are equivalent and design a time series that corresponds to the anomalous diffusion equation proposed.

Survival, Growth, and Development in the Early Stages of the Tropical Gar Atractosteus tropicus: Developmental Critical Windows and the Influence of Temperature, Salinity, and Oxygen Availability

This article uses embryos and larvae of Atractosteus tropicus as a model to study fish survival, growth, and development as a function of temperature, salinity, and air saturation during developmental periods. Results suggest identifiable critical windows of development in the early ontogeny of A. tropicus and contribute to the knowledge of fish larval ecology and the interactions of individuals × stressors × time of exposure.

Reduced reflectance and altered color: The potential cost of external particulate matter accumulation on urban Rock Pigeon (Columba livia) feathers

Authors of the article state that airborne particulate matter (PM) can accumulate on feather surfaces and alter feather appearance, so they quantified PM accumulation on Rock Pigeon feathers and analyzed the spectral properties of extracted particulates. Their findings suggest that wild birds could incur an urban pollution penalty as PM accumulation has the potential to alter feather properties.

Evolutionary models of lateralization: Steps toward stigmergy?

Article discusses an interesting approach to accounting for brain and behavioral asymmetry based on competition and cooperation in phenotypically asymmetric individuals. The model in question shows, in an almost fully analytical way, that under proper conditions, there exists an unequal number of equilibrium of left-and right-lateralized individuals.

Inhaled diesel exhaust particles result in microbiome‑related systemic inflammation and altered cardiovascular disease biomarkers in C57Bl/6 male mice

Article discusses the authors' investigation the hypothesis that exposure to inhaled diesel exhaust particles alters the gut microbiome and promotes microbial-related inflammation and cardiovascular disease biomarkers. To determine whether probiotics could prevent diet or DEP exposure mediated alterations in the gut microbiome or systemic outcomes, a subset of animals on the HF diet were treated orally with 0.3 g/day (~ 7.5 × 108 CFU/day) of Winclove Ecologic® Barrier probiotics throughout the study.

Effectiveness of a Single Prolonged Aerobic Exercise Session on Executive Function Task Performance in Physically Active Adults (21–70 Years of Age) (open access)

Effectiveness of a Single Prolonged Aerobic Exercise Session on Executive Function Task Performance in Physically Active Adults (21–70 Years of Age)

Authors of the article sought to examine the effectiveness of an acute prolonged exercise session on post-exercise executive function in physically active adults and to assess if age or pre-exercise cognitive performance was predictive of the magnitude of change in executive task performance. Their results support the effectiveness of a single prolonged exercise bout to augment executive function in physically active adults, irrespective of age.
