Summary: This study examines several analytical techniques, including Near Infrared (NIR) and Mid-Infrared (MIR) spectroscopy, Hyper Spectral Imaging (HSI), Gas Chromatography coupled to Mass Spectrometry (GC-MS) and Proton-transfer Reaction Time -of-Flight Mass spectrometry (PTR-TOF-MS), combined with chemometrics, to evaluate their potential in solving food authenticity questions, using rice as a case. The results show that GC-MS is the most accurate method for origin assessment, with prediction rates ranging from 86% to 94%, and data fusion experiments combining GC-MS with NIR or HSI resulted in prediction rates of more than 90%. For variety assessment, HSI achieved prediction values above 90% for all classes, and data fusion experiments combining GC-MS with NIR or HSI resulted in prediction values of 98%.

Summary: The study reveals that stormwater runoff has an impact on the concentration of dissolved organic matter (DOM) in Shili River, Jiujiang, China, particularly in the middle reaches. Critical pollutants and DOM concentrations increased due to the runoff. Three humic-like and two protein-like components of DOM were identified using 3DEEM-PARAFAC and UV-Vis spectroscopy. DOM mainly originates from autochthonous sources and is minimally affected by runoff.

Summary: Data envelopment analysis (DEA) is a popular method for evaluating the efficiency of decision-making units (DMUs). However, it has limitations when there is a lack of DMUs or too many variables. This article proposes CI-DEA as a solution, which aggregates data by replacing variables, making the results easy to interpret and understand.

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.
