Novel Approach for Efficient Separation of Primary Amines Using Supercritical Fluid Chromatography.
Chirality

State Key Laboratory of Food Science and Resources, Jiangnan University, Wuxi, Jiangsu, China.
Efficient enantioselective separation is a critical process in pharmaceutical and chemical industries for the production of chiral compounds. Herein, we developed a novel approach for the efficient enantioselective separation of primary amines using supercritical fluid chromatography (SFC) with a commercially available SFC column, Cel1. The key factors of separation, including cosolvent ratios, total cosolvent percentages, and temperature, were systematically assessed in this study.

Food Laboratory of Zhongyuan, Luohe, 462000, Henan Province, PR China.
Background: Edible oils are susceptible to contamination with polycyclic aromatic hydrocarbons (PAHs) throughout production, storage, and transportation processes due to their lipophilic nature. The necessity of quantifying PAHs present in complex oil matrices at trace levels, which bind strongly to impurities in oil matrices, poses a major challenge to the accurate quantification of these contaminants. Therefore, the development of straightforward and effective methods for the separation and enrichment of PAHs in oil samples prior to instrumental analysis is paramount to guaranteeing food safety.

Alzheimer's Therapeutic Research Institute, University of Southern California, San Diego, CA, United States.
Background: Investigators conducting clinical trials have an ethical, scientific, and regulatory obligation to protect the safety of trial participants. Traditionally, safety monitoring includes manual review and coding of adverse event data by expert clinicians.
Objectives: Our study explores the use of natural language processing (NLP) and artificial intelligence (AI) methods to streamline and standardize clinician coding of adverse event data in Alzheimer's disease (AD) clinical trials.

Recent advancements in fluorescence-based biosensor technologies have enabled more precise and accurate Förster Resonance Energy Transfer (FRET) imaging within Agrobacterium-mediated plant transformation systems. However, the application of FRET imaging in plant tissues remains hindered by significant challenges, particularly the time-intensive process of generating transgenic lines and the complications arising from tissue autofluorescence. In contrast, protoplast-based FRET imaging offers a rapid and efficient platform for functional screening and analysis, making it an essential tool for plant research.

Jt Comm J Qual Patient Saf
November 2024
Conceptual Framework: The Surgical Pause is a rapid, scalable strategy for health care systems to optimize perioperative outcomes for high-risk, frail patients considering elective surgery. The first and most important step is to screen for frailty, thereby identifying the 5% to 10% of patients at most risk for postoperative complications, loss of independence, institutionalization, and mortality. The second step is to take action to improve outcomes.
