On March 9, 2012, the New York Academy of Sciences brought together experts representing a variety of perspectives--including academic, industrial, regulatory, as well as those from physicians and consumers--to discuss considerations for the non-biological complex drug (NBCD) regulatory approval pathway, given the emerging regulatory guidelines for biosimilars (follow-on biological complex drugs). Some of the organizers of the conference expressed their belief that NBCDs share a number of characteristic features with biologicals: the structure cannot be fully defined by the available (physicochemical) analytical tests, and quality assurance is based on in-depth knowledge, consistency, and control of the production process. However, their view on NBCDs was not universally accepted among the experts who participated in the conference. Plenary sessions addressed the most recent regulatory developments, experimental design, interchangeability, and immunogenicity issues for follow-on versions of complex drugs from the perspective of key audiences, including industry, regulatory agencies, physicians, and consumers. This report summarizes these various perspectives on NBCDs and the scientific and regulatory considerations associated with complex drug categories.

Illicit drug abuse poses a significant global threat to public health and social security, highlighting the urgent need for rapid, sensitive, and versatile detection technologies. To address the limitations of traditional chromatographic techniques-such as high costs and slow response times-and the drawbacks of conventional immunochromatographic sensors (ICS), including low sensitivity and non-intuitive signal outputs, a fluorescence-quenching ICS (FQICS) was developed. This sensor leverages fluorescence resonance energy transfer (FRET) between aggregation-induced emission fluorescent microspheres (AIEFMs) and gold nanoparticles (AuNPs).

In this study, a novel carbon dots-based system was developed for the sequential quantification of Au and L-cysteine (L-Cys). The system comprises N,F-doped carbon dots (N,F-CDs), a custom-designed miniaturized fluorimeter, and test strips. The N,F-CDs exhibit outstanding optical properties, including a large Stokes shift (127 nm) and high fluorescence intensity.

This review describes new strategies in the use of multifunctional organic alkalizers (OA) for the fabrication of advanced functional materials. OA facilitate solubilization and delivery of poorly solubilized drugs through the formation of drug-OA complexes and supramolecular gels. OA are applied for the synthesis of materials for biomedical, energy storage, catalytic, photovoltaic, sensor, and electronic applications.

Background And Objectives: Older adults living with dementia are a heterogeneous group, which can make studying optimal medication management challenging. Unsupervised machine learning is a group of computing methods that rely on unlabeled data-that is, where the algorithm itself is discovering patterns without the need for researchers to label the data with a known outcome. These methods may help us to better understand complex prescribing patterns in this population.

Background: The dysregulation of long-chain noncoding RNAs (lncRNAs) causes several complex human diseases including neurodegenerative disorders across the globe.
Methods And Results: This study aimed to investigate lncRNA expression profiles of Withania somnifera (WS)-treated human neuroblastoma SK-N-SH cells at different timepoints (3 & 9 h) and concentrations (50 & 100 µg/mL) using RNA sequencing. Differential gene expression analysis showed a total of 4772 differentially expressed lncRNAs, out of which 3971 were upregulated and 801 were downregulated compared to controls.
