Gross alpha & beta measurement is a widely used technique for rapid screening of radionuclide content. The study evaluated the influence of geometry, alpha & beta energy and presence of natural decay chain nuclides on the observed gross alpha & beta response. Measured calibration data were validated using Monte Carlo-based modelling. Total and calculated gross activities were compared for a range of nuclear waste fingerprints, with significant deviation observed for many of the fingerprints evaluated. For operationally-exposed materials, systematic beta biases were observed dependent on the dominant nuclide present.

Therapeutic Potential and Mechanistic Insights of a Novel Synthetic α-Lactalbumin-Derived Peptide for the Treatment of Liver Fibrosis.
J Clin Exp Hepatol
December 2024
Biochemistry and Molecular Biology Department, Theodor Bilharz Research Institute, Giza, Egypt.
Background: Liver fibrosis is a serious global health issue, but current treatment options are limited due to a lack of approved therapies capable of preventing or reversing established fibrosis.
Aim: This study investigated the antifibrotic effects of a synthetic peptide derived from α-lactalbumin in a mouse model of thioacetamide (TAA)-induced liver fibrosis.
Methods: analyses were conducted to assess the physicochemical properties, pharmacophore features, and docking interactions of the peptide.
Hydrodynamic cavitation induced fabrication of soy protein isolate-polyphenol complexes: Structural and functional properties.

The combination of polyphenols and protein can improve the functional characteristics of protein. How to effectively promote the binding of polyphenols to protein is still a difficult topic. In this study, hydrodynamic cavitation (HC) was used to induce the fabrication of complexes between soy protein isolate (SPI) and different polyphenols (tannic acid (TA), chlorogenic acid (CGA), ferulic acid (FA), caffeic acid (CA), and gallic acid (GA)).

Objective: Although pegylated interferon α-2b (PEG-IFN α-2b) therapy for chronic hepatitis B has received increasing attention, determining the optimal treatment course remains challenging. This research aimed to develop an efficient model for predicting interferon (IFN) treatment course.
Methods: Patients with chronic hepatitis B, undergoing PEG-IFN α-2b monotherapy or combined with NAs (Nucleoside Analogs), were recruited from January 2018 to December 2023 at Tianjin Third Central Hospital.
Bioinformatic and biochemical analysis uncovers novel activity in the 2-ER subfamily of OYEs.
RSC Chem Biol
January 2025
Department of Chemistry, Emory University Atlanta GA 30322 USA
Members of the old yellow enzyme (OYE) family utilize a flavin mononucleotide cofactor to catalyze the asymmetric reduction of activated alkenes. The 2-enoate reductase (2-ER) subfamily are of particular industrial relevance as they can reduce α/β alkenes near electron-withdrawing groups. While the broader OYE family is being extensively explored for biocatalytic applications, oxygen sensitivity and poor expression yields associated with the presence of an Fe/S cluster in 2-ERs have hampered their characterization.
