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).

Instructional Models for Course-Based Research Experience (CRE) Teaching (open access)

Instructional Models for Course-Based Research Experience (CRE) Teaching

This article presents a study that was done over a period of 3 years to explicate the instructional processes involved in teaching an undergraduate course-based research experience (CRE). The study presented here delineated a set of specific instructional practices used by active CRE instructors and modeled the relations between the use of these practices and specified outcomes. The resultant educational models should provide clarification of the ways in which the aims of CRE can be effectively achieved by instructors.

The metabolic cost of turning right side up in the Mediterranean spur-thighed tortoise (Testudo graeca) (open access)

The metabolic cost of turning right side up in the Mediterranean spur-thighed tortoise (Testudo graeca)

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.

Magnetic plasma expulsion (open access)

Magnetic plasma expulsion

The article presents one scheme for what is referred to as magnetic plasma expulsion, which would prevent the plasma from entering a given region. Magnetic plasma expulsion techniques may allow instrumentation access to the interiors of plasmas. Magnetic plasma expulsion techniques may also make alternative approaches for magnetic plasma confinement possible. Particle-in-cell simulation with the Warp code is used to study magnetic plasma expulsion. Some conditions for achieving magnetic plasma expulsion are reported.

A novel benzimidazole derivative, MBIC inhibits tumor growth and promotes apoptosis via activation of ROS-dependent JNK signaling pathway in hepatocellular carcinoma (open access)

A novel benzimidazole derivative, MBIC inhibits tumor growth and promotes apoptosis via activation of ROS-dependent JNK signaling pathway in hepatocellular carcinoma

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.

Analysis of the Fe 2p XPS for hematite 𝛂 Fe2O3: Consequences of covalent bonding and orbital splittings on multiplet splittings

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.

Phosphorus deprivation affects composition and spatial distribution of membrane lipids in legume nodules

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.

Using CRISPR/Cas to enhance gene expression for crop trait improvement by editing miRNA targets (open access)

Using CRISPR/Cas to enhance gene expression for crop trait improvement by editing miRNA targets

Article states that gene editing tools such as CRISPR/Cas9 are often thought of as a means to prevent gene expression; however, a more subtle and yet powerful approach is the enhancement of gene expression by precise deletion of repressor sites within a gene of interest. Authors argue that gene editing of miRNA target sites is preferable over deletion of the miRNA genes themselves, given that it avoids the pitfalls of unspecific derepression of miRNA target(s) beyond the gene of interest.

Ignition delay times of NH3/DME blends at high pressure and low DME fraction: RCM experiments and simulations (open access)

Ignition delay times of NH3/DME blends at high pressure and low DME fraction: RCM experiments and simulations

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.
