This article studies the solubility of meloxicam in dimethyl sulfoxide (DMSO)-aqueous solvent systems at several temperatures from 273.15 to 313.15 K to expand the solubility database about analgesic drugs in mixed solvents.

Article demonstrating a technique utilizing acoustic metasurfaces (AMSes) with high reflective characteristics using relatively lightweight materials for noise reduction without any change in mechanical strength or weight of the tire. The proposed design can significantly reduce the noise arising from tire–pavement interaction over a broadband of acoustic frequencies under 1000 Hz and over a wide range of vehicle speeds using a negative effective dynamic mass density approach.

This article is a commentary on the future of legume genetic data resources and summarizes the workshop held in March of 2019 by the Legume Genomic Data Working Group that addressed questions of data resources and priorities for legumes.

Article investigating the effect of hexadecyltrimethylammonium bromide (CTAB) concentration on the galvanostatic electrodeposition of Ni-B matrix nano hexagonal boron nitride (hBN) reinforced composite coatings.

Article detects the presence of a specific pancreatic cancer-derived miRNA (pre-miR-132) using the fluorescence properties of biocompatible nitrogen-doped graphene quantum dots (NGQDs) synthesized using a bottom-up approach from a single glucosamine precursor. This non-invasive approach allows cancer-specific miRNA detection to facilitate early diagnosis of various forms of cancer.

This article presents the calculation of the standard enthalpies of vaporization, sublimation and solvation of organic molecules using a common computer algorithm on the basis of a group-additivity method.

This article uses currently available software and techniques to describe a workflow to analyze ¹³C-labeled isotopologues of the membrane lipid and storage oil lipid intermediate—phosphatidylcholine (PC). Results demonstrated greater ¹³C-isotopic labeling in the cotyledons of developing embryos compared with the embryonic axis.

This article explores the ability of Arabidopsis thaliana to recover after exposure to freezing temperatures.

This article identifies discriminant metabolites between a resistant (R) and a susceptible (S) sugarcane variety at the early stages of pathogen colonization (30 and 120 days after inoculation—DAI) by untargeted and targeted metabolomics of leaves and xylem sap using gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-tandem mass spectrometry (LC-MS/MS). The data represent a valuable resource of potential biomarkers for metabolite-assisted selection of resistant varieties to RS.

Paper discusses metabolomics studies that link changes in primary or specialized metabolism to the defense responses of plants against bacterial, fungal, nematode, and viral pathogens.

This article considers an analogous problem in which the observed random variables are the steps of a symmetric random walk. Assuming continuously distributed step sizes, it describes the optimal stopping rules for the cases n = 2 and n = 3 in two versions of the problem: a "full information" version in which the actual steps of the random walk are disclosed to the decision maker; and a "partial information" version in which only the relative ranks of the positions taken by the random walk are observed. When n = 3, the optimal rule and expected rank depend on the distribution of the step sizes. The authors give sharp bounds for the optimal expected rank in the partial information version, and fairly sharp bounds in the full information version.

Article on new markers of tumor metastasis. The authors found that expression of DP103 was significantly upregulated in the metastatic basal subtype of breast cancers in 3 independent cohorts. This elevated DP103 expression correlated with metastatic breast cancer gene signatures and was strongly associated with patient survival. This study provides the first evidence that the RNA helicase DEAD-box protein DP103 is an NF-kB target that could form part of a positive feedback loop contributing to DP103- mediated regulation of TAK1 kinase activity on the major NF-kB kinase IKK2, thus implicating DP103 in the maintenance of this oncogenic signaling arm in human cancer.

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.

Article describes study in which researchers characterized the influence of temperature on arterial acid–base balance and intracellular pH (pHi) in the bimodal-breathing swamp eel, Monopterus albus.

This article communicates the results of a study conducted on red-winged blackbirds where brain phospholipid composition during development was measured and diet was manipulated. The dietary study confirmed that nestling brains are sensitive to fatty acid supply. The findings of this article suggest that Red-winged blackbirds may be able to advance cognitive development relative to other altricial species owing to their aquatic maternal diet.

This article describes a study investigating the maturation of convective oxygen transport in embryos of the snapping turtle (Chelydra serpentina). Measurements included: mass, oxygen consumption, heart rate, blood oxygen content and affinity and blood flow distribution at 50%, 70% and 90% of the incubation period.

This article posits that the frequently abrupt environmental changes accompanying much longer-term general climate change require consideration of the true nature of environmental change coupled with an expansion of focus to consider developmental phenotypic plasticity.

This article examining the correlation between pulmonary compliance, lung volume, and lymph flux rates in anurans. The findings of this article suggest that lymph mobilization capacity may explain some of the variation in pulmonary compliance and lung volume in anurans.

This column article discusses the impact of Robert Boutillier and Graham Shelton's 1986 Journal of Experimental Biology paper "Gas exchange, storage and transport in voluntarily diving Xenopus laevis."

Article explores the ‘membrane pacemaker’ hypothesis which proposes a biochemical explanation for among-species variation in resting metabolism, based on the positive correlation between membrane docosahexaenoic acid (DHA) and metabolic rate. The authors tested this hypothesis using a novel model, altricial red-winged blackbird nestlings, predicting that the proportion of DHA in muscle and liver membranes should increase with the increasing metabolic rate of the nestling as it develops endothermy. In support of the membrane pacemaker hypothesis, DHA proportions increased in membranes from pectoralis muscle, muscle mitochondria and liver during post-hatch development. By contrast, elevated dietary DHA had no effect on resting metabolic rate, despite causing significant changes to membrane lipid composition.

This article is a study using crude oil as an example of an environmental stressor in adult zebrafish. The offspring obtained were then assessed for transgenerational epigenetic transfer of oil-induced phenotypes. The authors conclude that epigenetic transgenerational inheritance can lead to an immediate and simultaneous inheritance of both beneficial and maladaptive traits in a large proportion of the F1 larvae. The adaptive responses may help fish populations survive when facing transient environmental stressors.

Article describes study which investigated the importance of atrial contraction in filling of the ventricle in American alligators (Alligator mississippiensis) by bypassing both atria (with the use of ligatures to prevent atrial filling) and measuring the resultant effects on cardiac output in anesthetized animals.

This article is a study investigating the blood flow patterns and heart rate in surfacing and during graded, submerged swimming activity in common snapping turtles. The effects of beta-adrenergic and cholinergic receptor blockade on blood flow and heart rate during these activities are also studied.
