Abstract: Errors are found in the mathematical correlation based on the combined Jouyban-Acree and Modified Apelblat model for describing the variation in the mole fraction solubility of cefpiramide with temperature and solvent composition for the binary aqueous-ethanol solvent system. The equation coefficents given by Tang and coworkers, when substituted into the model equation, do not yield the authors' calculated mole fraction solubilities of cefpiramide.

This article presents research where various kudzu accessions were analyzed through barcoding and comparative transcriptomics, generating tools for identification and molecular pathway analysis.

Article describes study which assesses the relative accuracy of volunteer water quality data collected by the Texas Stream Team (TST) citizen science program from 1992–2016 across the State of Texas by comparing it to professional data from corresponding stations during the same time period.

Article discusses the determination of the spectrum of two interesting stochastic matrices appearing in an engineering paper.

Article examining the population mobility and air quality before and after the lockdown (mandated restriction of activity) during the public health response to COVID-19. This article is part of the Special Issue on COVID-19.

Article analyzes the origins of the complex Fe 2p X-Ray Photoelectron Spectra (XPS) of hematite (α-Fe₂O₃) and is related to the character of the bonding in this compound. This analysis provides a new and novel view of the reasons for XPS binding energies (BEs) and BE shifts, which deepens the current understanding and interpretation of the physical and chemical significance of the XPS. This article is part of the JCP Special Topic on Oxide Chemistry and Catalysis.

Article describes the devastating effects of nuclear radiation and its long-lasting consequences on Earth’s ecosystems. The authors call upon all scientists to communicate the importance of the environmental impacts of such an event to all life forms on Earth, including humankind.

Article synthesizing and testing the synthetic peptide AKRRRLSSLRASTSKSESSQK (56-21) which corresponds to the carboxyl-terminal 21 amino acids of human ribosomal protein S6 as a substrate for S6/H4 kinase purified from human placenta. The data suggests that multiple S6 kinases may be required to phosphorylate S6 at all five sites which are modified in vivo.

Article theoretically demonstrates a single low frequency gas detector that can be used for sensing of gas mixtures with high selectivity, accuracy, and sensitivity.

Article explores the question of whether animals with switched phenotypes during early development are unable to return to a normal range of adult phenotypes, or whether they do not experience the specific environmental conditions necessary for them to switch back to the normal range of adult phenotypes.

This article develops a theory of electromagnetic transmission through dielectric-metal superlattices with ultra-thin metal films, in which electron motion in the direction perpendicular to the metal surfaces is quantized.

Article describes how products of plant secondary metabolism, such as phenolic compounds, flavonoids, alkaloids, and hormones, play an important role in plant growth, development, stress resistance. The authors state that the overall goal of this study was to develop a high-throughput workflow to identify and quantify plant polyphenols.

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.

Article studying an underappreciated complexity in pathways for synthesis and accumulation of Triacylglycerols from plants, familiar to most people as vegetable oils.

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).

This article describes a new methodology for monitoring sucrose labeling using liquid chromatography tandem mass spectrometry (LC-MS/MS). To date, the most commonly used method to monitor sucrose labeling is by nuclear magnetic resonance, which requires substantial amounts of biological sample.

Article presents research on how temperature affects fish populations. The study shows how changes in temperature may induce craniofacial and morphological alterations in fish during early stages and contribute to understanding the possible effects of global warming in early development of fish and its ecological implications.

Authors of the article describe how autoignition delay times of ammonia/dimethyl ether (NH3/DME) mixtures were measured in a rapid compression machine with DME fractions of 0, 2 and 5 and 100% in the fuel. Analysis of the mechanism indicates that this 'early DME oxidation' generates reactive species that initiate the oxidation of ammonia, which in turn begins heat release that raises the temperature and accelerates the oxidation process towards ignition. This is the accepted manuscript version of the published article.

This study further explores a prior screening program carried out using MTT assay that identified a series of novel benzimidazole derivatives, among which Methyl 2-(5-fluoro-2-hydroxyphenyl)-1H-benzo[d]imidazole-5-carboxylate (MBIC) showed highest anticancer efficacy compared to that of chemotherapeutic agent, cisplatin. In this article, the authors find that MBIC inhibited cell viability in different hepatocellular carcinoma (HCC) cell lines without exerting significant cytotoxic effects on normal liver cells. The results of this study demonstrate that MBIC may inhibit cell proliferation via ROS-mediated activation of the JNK signaling cascade in HCC cells.

Article investigating if the exposure to diesel exhaust particles (DEP) can alter commensal lung microbiota, thereby promoting alterations in the lung’s immune and inflammatory responses. This article also explores if diet contributes to the alteration of the commensal lung microbiome.

Article assessing membrane lipids in M. truncatula tissues using electrospray ionization–mass spectrometry. The results suggest that specific PC species may be differentially important in diverse nodule zones and cell types, and that membrane lipid remodeling during P stress is not uniform across the nodule.

This article describes the use of a gold nanoantenna array to enhance both the nonlinear refractive index and two-photon absorption (2PA) of the organic dye 4,4'-bis(diphenylamino)stilbene (BDPAS), which is known as a dye with relatively large 2PA.

Article examining the the metabolic cost of self-righting in the terrestrial Mediterranean spur-thighed tortoise using respirometry and kinematic video analysis and comparing this to the metabolic cost of locomotion at a moderate, easily sustainable speed. The results found that self-righting is, relatively, metabolically expensive and costs around two times the mass-specific power required to walk.
