A rapid thioacidolysis method for biomass lignin composition and tricin analysis (open access)

A rapid thioacidolysis method for biomass lignin composition and tricin analysis

This article developed a modified, rapid higher throughput thioacidolysis method to analyze both lignin monomeric composition and tricin content in the lignin polymer. The results demonstrate that the modified method can be used for rapid, high-throughput, and reliable lignin composition and tricin content analyses for screening transgenic plants for cell wall modifications or in large-scale genome-wide association studies (GWAS).

A gene-editing/complementation strategy for tissue-specific lignin reduction while preserving biomass yield (open access)

A gene-editing/complementation strategy for tissue-specific lignin reduction while preserving biomass yield

This article develops a method, using a single DNA construct that uses CRISPR–Cas9 gene editing to knock-out expression of an endogenous gene of lignin monomer biosynthesis while at the same time expressing a modified version of the gene’s open reading frame that escapes cutting by the Cas9 system and complements the introduced mutation in a tissue-specific manner. This method is applicable to any plant species in which transformation and gene editing are feasible and validated vessel-specific promoters are available.

The accessory role of the diaphragmaticus muscle in lung ventilation in the estuarine crocodile Crocodylus porosus (open access)

The accessory role of the diaphragmaticus muscle in lung ventilation in the estuarine crocodile Crocodylus porosus

This article explores lung ventilation in crocodilians through direct measurements of ventilation, metabolic rate, and arterial blood gases of juvenile estuarine crocodiles in varying conditions. The results suggest that, in C. porosus, costal ventilation alone is able to support metabolic demands at rest, and the diaphragmaticus is largely an accessory muscle used at times of elevated metabolic demand.

In situ cardiac performance of Atlantic cod (Gadus morhua) at cold temperatures: long-term acclimation, acute thermal challenge and the role of adrenaline (open access)

In situ cardiac performance of Atlantic cod (Gadus morhua) at cold temperatures: long-term acclimation, acute thermal challenge and the role of adrenaline

This article measures the cardiac performance of Newfoundland Atlantic cod (Gadus morhua). The results: (1) show that maximum performance of the isolated cod heart is not compromised by exposure to cold temperatures; and (2) support data from other studies, which show that, in contrast to salmonids, cod cardiac performance/myocardial contractility is not dependent upon humoral adrenergic stimulation.

Childhood Asthma and Smoking: Moderating Effect of Preterm Status and Birth Weight

Article exploring the association between second-hand smoke exposure, asthma, and asthma severity in children ages 6-17 as well as the effect of birth weight and prematurity (BWP) on parental smoking and asthma. Results indicate that focused asthma interventions in children should inquire about BWP status as well as parental smoking and household smoke exposure to reduce asthma morbidity and mortality.

Upper lethal temperatures of Northern Bobwhite embryos and the thermal properties of their eggs (open access)

Upper lethal temperatures of Northern Bobwhite embryos and the thermal properties of their eggs

This article explores the upper lethal temperature for Bobwhite eggs. Results find that thermal tolerances of Northern Bobwhite embryos are high, indicating an adaptation to the naturally occurring temperature extremes in the Bobwhite's environment. However, the results also indicate that high temperatures could have plausibly contributed to the population decline observed in the Bobwhite's semi-arid range.

Collaborative Research: A Systematic and Comprehensive Study of Black Hole-Driven Turbulence in Massive Galactic Systems

Data management plan for the grant, "Collaborative Research: A Systematic and Comprehensive Study of Black Hole-Driven Turbulence in Massive Galactic Systems." This research team has developed a technique to measure gas turbulence in systems hosting giant central black holes and will directly evaluate the viability of this mechanism using a large sample of galaxies. This project will deliver a more complete view of the “feedback” provided by accreting SMBHs, leading to a better understanding of the black hole-host galaxy relation. More specifically, it will directly probe the energetics of the intra-cluster, circum-galactic, and interstellar media of massive early-type galaxies.
