Per- and polyfluoroalkyl substances (PFAS) are a large class of chemicals of concern for both human and environmental health because of their ubiquitous presence in the environment, persistence, and potential toxicological effects. Despite this, ecological hazard data are limited to a small number of PFAS even though there are over 4000 identified PFAS. Traditional toxicity testing will likely be inadequate to generate necessary hazard information for risk assessment.

J Phys Chem Lett

January 2025

Hefei National Research Center for Physical Sciences at the Microscale, School of Chemistry and Materials Science, University of Science and Technology of China, Hefei, Anhui 230026, China.

Heterogenous single-atom catalysts (SACs) are reminiscent of homogeneous catalysts because of the similarity of structural motif of active sites, showing the potential of using the advantage of homogeneous catalysts to tackle challenges in hetereogenous catalysis. In heterogeneous oxygen electrocatalysis, the homogeneity of adsorption patterns of reaction intermediates leads to scaling relationships that limit their activities. In contrast, homogeneous catalysts can circumvent such limits by selectively altering the adsorption of intermediates through secondary coordination effects (SCEs).

Application of predictive modeling tools for the identification of Ocimum spp. herbal products.

Anal Bioanal Chem

January 2025

Intercollege Graduate Degree Program in Plant Biology, Pennsylvania State University, University Park, PA, USA.

Species identification of botanical products is a crucial aspect of research and regulatory compliance; however, botanical classification can be difficult, especially for morphologically similar species with overlapping genetic and metabolomic markers, like those in the genus Ocimum. Untargeted LC-MS metabolomics coupled with multivariate predictive modeling provides a potential avenue for improving herbal identity investigations, but the current dearth of reference materials for many botanicals limits the applicability of these approaches. This study investigated the potential of using greenhouse-grown authentic Ocimum to build predictive models for classifying commercially available Ocimum products.

Introduction: Pancreatoduodenectomy (PD) may occasionally be indicated for complete removal of periampullary (duodenal and ampullary) adenomas (PAs). As compared with malignant indications, PD for benign or pre-malignant disease is often associated with increased morbidity. While the Spigelman classification assesses malignancy risk for familial adenomatous polyposis (FAP)-related duodenal adenomas, no malignancy risk score (MRS) exists for non-FAP related PAs.

The synthesis of novel highly phosphorescent N^C^N tridentate platinum(II)-complex-peptide nucleic acid (PNA) bioconjugates was accomplished through the solid-phase approach. Melting temperature measurements and circular dichroism spectroscopy studies demonstrated that these conjugates maintain the PNA ability to recognize complementary ssDNA and ssRNA, though the length of the spacer between the metal center and the PNA sequence affects their hybridization properties. Noteworthy, the conjugation of PNA to this family of Pt(II) complexes significantly enhanced the luminescent features of the organometallic moiety, leading to increased quantum yields (82.
