Summary: This study thoroughly explores the potential energy surfaces of DMSO clusters and analyzes the non-covalent interactions in these clusters using quantum theory. The strongest and weakest non-covalent interactions in DMSO clusters are found to be CH center dot center dot center dot O hydrogen bonding and H center dot center dot center dot H bonding, respectively. Additionally, the temperature-dependent isomer distribution of the investigated clusters is reported, and the performance of ten density functional theory functionals in calculating the binding energies of DMSO clusters is assessed.

Summary: Mesophyll conductance (g(m)) is negatively correlated with the age of wheat leaves but positively correlated with the surface area of chloroplasts exposed to intercellular airspaces (S-c). The decline in photosynthetic rate and g(m) is slower for water-stressed plants as leaves age compared to well-watered plants. The recovery from water stress upon rewatering depends on leaf age, with the strongest recovery for mature leaves.

Summary: This study integrated density functional theory with dispersion scheme (DFT-D) and various experimental methods to investigate the intercalation of dimethyl sulfoxide (DMSO) in kaolinite with and without hydration. It highlighted the kinetic, thermodynamic, and structural impacts of hydration, showing that water molecules significantly promote intercalation of DMSO into kaolinite due to favorable intercalation energy enabled by effective hydrogen bonding.

Summary: Hydrogen/deuterium (H/D) exchange combined with two-dimensional (2D) NMR spectroscopy is widely used for studying the structure, stability, and dynamics of proteins. This article introduces the dimethylsulfoxide (DMSO)-quenched H/D-exchange method and its applications in protein science. The method involves replacing the H/D-exchange buffer with an aprotic DMSO solution, which quenches the exchange reaction. The improved DMSO-quenched method allows for monitoring the H/D exchange of proteins at high concentrations of salts or denaturants.

Summary: This study compared the ultrasound-assisted extraction (UAE) process for chlorophylls and carotenoids at laboratory and pilot scale, and found that UAE can significantly improve extraction yield. While the effect was less prominent at pilot scale, the scale-up experiment revealed the required ultrasound power density for equal extraction yield at both scales.

Summary: Dielectric relaxation spectra were measured for mixtures of deep eutectic solvents (DESs) with dimethylsulfoxide (DMSO) to reveal the formation of contact ion pairs (CIPs) at moderate DES concentrations, causing pronounced maxima in the static permittivity of the mixtures. Solute-solvent interactions slowed down the rotational motion of solvating DMSO molecules, indicating micro-heterogeneity within the studied mixtures.

Summary: Leaf toughness is an important plant adaptation to herbivore pressure and environmental stress. This study measured leaf toughness, anatomy, and photosynthetic traits in 103 tree species from a tropical rainforest in Malaysia. The results showed that leaf toughness, leaf mass per area, thickness, and carbon and nitrogen contents increased with tree height. Heterobaric leaves had greater toughness compared to homobaric leaves.

Summary: This study evaluated changes in secondary metabolites in horse chestnut leaves and their response to invasion by the horse-chestnut leaf miner. The results showed variations in metabolite composition and sensitivity to invasion among leaves collected from different locations. The plant exhibited clear physiological and anatomical changes in response to the stress factor, with catechins playing a role in plant resistance. An enhanced accumulation of phenolic compounds and hypertrophy were observed in leaves affected by the pest.

Summary: The study investigated the influence of abiotic and biotic factors on DMSP and DMSO concentrations in the Belgian coastal zone during two annual cycles in 2016 and 2018. While significant differences in Chl-a concentrations were observed between the two years, the DMSP and DMSO patterns remained consistent. This suggests that despite fluctuations in Chl-a levels, the overall DMSP and DMSO dynamics were stable over the two years.

Summary: Hydrogen bonding is crucial in biological processes for stabilizing proteins, lipids, and controlling enzyme reactions. Hyper-Raman scattering was used to study molecular interactions in the DMSO-H2O system for the first time, revealing evidence of intermolecular bonds between water and DMSO. This demonstrates the potential of hyper-Raman spectroscopy in investigating model system bonding.

Summary: We report the first observation of phototriggered isomerization of dmso ligands on a bis sulfoxide complex, [Ru(bpy)(2)(dmso)(2)], in the crystalline solid state. The UV-vis spectrum of the crystal shows an increase in optical density around 550 nm after irradiation, consistent with solution isomerization results. Digital images of the crystal before and after irradiation exhibit a noticeable color change (pale orange to red) and cleavage occurs along planes (101) and (100) during irradiation. Single crystal X-ray diffraction data confirms isomerization throughout the lattice, with a structure containing a mix of S,S and O,O/S,O isomers obtained from a crystal irradiated ex situ. In situ irradiation XRD studies show an increase in the percentage of the O-bonded isomer with increasing 405 nm exposure time.

Summary: Alzheimer's disease is a major cause of senile dementia and is characterized by the aggregation of neurofibrillary tangles and amyloid plaques in the brain. The A beta 1-42 peptide is considered the primary cause of neurotoxicity due to its insolubility and subsequent aggregation. A beta 1-42 and A beta 1-40 have been identified as relevant biomarkers for AD diagnosis, and SurfaceAssisted Laser Desorption/Ionization Mass Spectrometry (SALDI-MS) was used to monitor the A beta 1-42/A beta 1-40 ratio without prior sample treatment.

Summary: We developed a CRISPR-empowered electrochemical biosensor, named PER-E-CRISPR, for amplification-free and sensitive detection of miR-21. The biosensor combines the advantages of CRISPR/Cas13a and primer exchange reaction (PER) for target amplification. Under optimized conditions, the PER-E-CRISPR assay exhibits a linear range from 10-13 to 10-7 M and a limit of detection of 30.2 fM. The biosensor shows excellent performance in actual plasma, indicating promising prospects for miRNA detection in molecular diagnosis.

Summary: Molecular docking (MD) analysis is widely used for studying the interaction between aptamers and small molecules. This study established steady-state aptamers of tertiary structures (SATS) using specific aptamers of tetracycline antibiotics as docking models. Molecular docking results revealed multiple binding sites in the SATS of aptamers, with significant variations in binding free energy (BFE) and docking score (DS). The study also proposed a method for MD analysis based on SATS, providing insights into binding mode and predicting binding sites.
