Context‐Dependent Effects of Apolipoprotein A2 on Lipid Metabolism and Atherogenesis

The FASEB Journal, Volume 40, Issue 12, 30 June 2026.
Proposed model of the pro‐atherogenic role of APOA2 in dyslipidemia. Under conditions of dyslipidemia (ldlr−/− and apoe−/− mice), APOA2 promotes a reduction in VLDL through its conversion to LDL via an LDLR‐independent pathway. LDL is then deposited to the aorta and aortic root. In the ldlr−/− mice, the presence of APOE may mitigate the rate of VLDL to

Direct Competitive Kinetic Isotope Effect Measurement Using Quantitative Whole Molecule Matrix‐Assisted Laser Desorption Ionization Time‐of‐Flight Mass Spectrometry

ChemBioChem, Volume 27, Issue 12, 26 June 2026.
Kinetic Isotope effect (KIE) measurements are a powerful tool to interrogate enzyme mechanisms and transition state structures. In this study, we develop a simple quantitative MALDI‐TOF mass spectrometry approach to measure competitive heavy atom KIEs.

Tracking of [14C]Polystyrene Nanoplastics in Pregnant Mice

Advanced Science, Volume 13, Issue 32, 9 June 2026.
This study investigates [14C]polystyrene nanoplastic ([14C]PS) translocation in late‐stage pregnant mice after intranasal (0.5 mg of [14C]PS on GD12, GD14, and GD16, n = 6) and intravenous administration (1.5 mg of [14C]PS on GD16, n = 6). 14C‐radiolabel allows quantitative tracking of unmodified polystyrene nanoplastics.

Net mineralizable soil phosphorus cannot be measured by non‐isotopic approaches

Agricultural &Environmental Letters, Volume 11, Issue 1, June 2026.
Abstract While radioisotopic pool dilution is widely regarded as the most reliable method for estimating soil phosphorus mineralization (Pmin), high costs, low throughput, and safety requirements limit its use. We evaluated the potential of non‐radioisotopic approaches to estimating net Pmin by difference before and after aerobic incubation, analogous ...

Cross‐stressor resilience of soil microbial growth and carbon metabolism under climate change

Ecology, Volume 107, Issue 6, June 2026.
Abstract The microbial ability to recover metabolism after perturbation events ensures ecosystem functional stability in a changing climate, where multiple climatic stressors increasingly occur in sequential and seasonally cyclic patterns. While prior exposure to a specific stress can enhance microbial resilience to that stress, whether this resilience
