The aim of this study was to investigate the influence of the duration of frozen storage (12 and 24 weeks) and the storage temperature (-18 °C or - 80 °C) on the shelf life of pork in MAP for up to 14 days after thawing. Frozen meat was compared to unfrozen meat in different physicochemical and microbiological parameters. The parameters a*, b*, pH value, cooking loss, shear force and antioxidant activity showed no significant changes depending on the freezing process. The total moisture loss was significantly higher for frozen/thawed pork compared to unfrozen pork. The storage loss of all frozen samples showed higher values than the unfrozen samples on all examination days. The level of TBARS reached comparable values for all experimental groups. On examination days 7 and 14, significantly lower values of total plate count (TPC) and Pseudomonas spp. were measured for frozen pork compared to unfrozen pork. The temperature of frozen storage had no significant influence on the quality of pork.

This study evaluates the impact of various processing steps in the human milk (HM) donation chain on nutritional composition and oxidative biomarkers, specifically focusing on triacylglycerols, glucose, polyphenols, and lipid peroxides. A total of 68 HM samples were collected from the Human Milk Bank of Córdoba (Argentina) between 2022 and 2023. The effects of storage and pasteurization using the Holder method were assessed.

Introduction: High-dose systemic prednisolone is the cornerstone treatment of many autoimmune- and inflammatory diseases. Since prednisolone shows non-linear protein binding at higher serum concentrations, quantification of the unbound prednisolone concentration is important to understand prednisolone pharmacokinetics. We developed a liquid chromatography-tandem mass spectrometry (LC-MS/MS) assay to quantify protein-unbound prednisolone in serum.

The critical challenges in developing ultralow-temperature proton-based energy storage systems are enhancing the diffusion kinetics of charge carriers and inhibiting water-triggered interfacial side reactions between electrolytes and electrodes. Here an acid-salt hybrid electrolyte with a stable anion-cation-HO solvation structure that realizes unconventional proton transport at ultralow temperature is shown, which is crucial for electrodes and devices to achieve high rate-capacity and stable interface compatibility with electrodes. Through multiscale simulations and experimental investigations in the electrolyte employing ZnCl introduced into 0.
