Summary: Experimental investigation on piezoresistive strain sensing of multiwalled carbon nanotube (CNT)-reinforced polymer nanocomposites reveals that the electrical resistance decreases nonlinearly when CNT is added up to 1.5 wt%, while agglomeration of CNT causes a decrease in electrical properties and mechanical properties of the nanocomposite at higher filler content. Additionally, it is shown that CNT agglomeration decreases strain sensing in the nanocomposite, and different piezoresistive behaviors are explained based on piezoresistivity mechanisms.

Summary: By doping multiwalled carbon nanotubes (MWCNTs) and single-stranded-DNA-wrapped MWCNTs into a nematic liquid crystal (NLC) mixture, composites were prepared to improve display performance. The uniformity of the composite was confirmed by polarized optical microscopy images, and an interaction between MWCNTs and the NLC was observed through infrared absorption spectra. The incorporation of MWCNTs and DNA-wrapped MWCNTs reduced threshold voltage and response time, improved stability, enhanced dielectric anisotropy and broadened frequency range, and demonstrated cooperative orientation and high conductivity.

Summary: The cholecystokinin-2 receptor (CCK2R), a target for drug development, is expressed in peripheral tissues and the central nervous system. In this study, cyclotide-containing plant extracts from Oldenlandia affinis, Viola tricolor, and Carapichea ipecacuanha were found to activate CCK2R. One representative cyclotide, caripe 11 from C. ipecacuanha, was identified as a partial agonist of CCK2R and exhibited a modulatory effect on the potency of CCK-8. These findings suggest that cyclotides like caripe 11 could be explored for the design and development of ligands or imaging probes targeting CCK2R and related peptide GPCRs.

Summary: By analyzing mRNA and protein data, we identified several key genes, functional processes, and pathways that play critical roles in PDAC. We found an interesting module associated with clinical traits, enriched in ribosome, hematopoietic cell lineage, and cell adhesion molecules-related pathways. We also identified hub genes in important modules associated with immune system processes. Additionally, survival analysis led to the identification of five genes as potential biomarkers or therapeutic targets for PDAC. Our findings may contribute to a better understanding of the molecular mechanisms and provide potential prognostic and therapeutic targets for PDAC.

Summary: This study aimed to investigate the impact of low nitrogen (LN), low phosphorus (LP), and their combined deficiency (LNP) on soybean. The findings showed that these conditions triggered changes in gene expression related to processes such as cell wall organization, defense response, oxidative stress response, and photosynthesis. The response, however, differed for each condition. Soybean exhibited enhanced uptake of nitrogen and phosphorus in response to LN and LP, respectively. The regulation of genes involved in cell wall organization also showed distinct patterns, with LP promoting the production of casparian strip and LN promoting secondary wall biosynthesis. Flavonoid biosynthesis was also affected differently, with LP promoting anthocyanin production and LN and LNP promoting isoflavonoid production. Interestingly, nutrient deficiencies reduced the expression of genes involved in defense response, indicating a role of nitrogen and phosphorus in plant disease resistance. Overall, this study provides detailed insights into the molecular and physiological effects of LN, LP, and LNP on soybean roots.

Summary: Using meta-analysis and machine learning methods, this study identified water stress-responsive genes in Populus and discovered important gene networks. The analysis revealed significant transcriptional variations occurring during drought stress, particularly in genes related to stress response, cellular catabolic process, metabolic pathways, and hormone-related genes. The study highlighted the importance of acetyltransferase NATA1-like and putative cytochrome P450 genes in response to drought stress, as well as the prominent roles of MYBs and MAPKs in drought stress response that could enhance drought tolerance in Populus. ARF2-like and PYL4-like genes were also suggested as potential markers for breeding programs. This study provides valuable insights into how Populus responds to drought and can be useful in improving stress tolerance in Populus.

The enthalpies of dissolution of azeotropes in different mediums were determined, and the impact of the structure of the azeotropes on their properties in solution was discussed. A correlation between enthalpies of solvation and molar refraction was used to determine the vaporization enthalpies of azeotropes for the first time. The results were found to be consistent with literature data, obtained using direct and calculated methods.

Summary: In this study, the interactions between doped and pristine coronenes and adenine nucleobases were investigated using Density Functional Theory. The optimal configurations, adsorption energies, charge transfer, and electrical properties of each complex were calculated. It was found that doped coronene had stronger adsorption strength and charge transfer compared to pristine coronene. The stability of the complexes was attributed to non-covalent interactions in the interactive region. The change in electrical conductivity of coronenes after adsorption suggested their sensitivity towards DNA bases. The predicted energy gap and prolonged recovery time for adenine-coronene configurations indicated the potential application of pristine/doped coronene in DNA detection.

Summary: This study evaluated the adsorption of zolpidem on magnetic graphene oxide and synthesized magnetic graphene oxide adsorbents for zolpidem removal. The best magnetic nanoadsorbent was found to have a removal percentage of 87.07% at specific pH and temperature conditions. The results suggest that the removal of zolpidem is related to the surface chemistry of the adsorbent rather than the surface area of graphene oxide. The adsorbent showed excellent adsorption efficiency and magnetic behavior, making it a promising material for removing zolpidem from aqueous solutions.
