Assessment and Correction of Non‐Linearity Effects for In Situ Rb‐Sr Geochronology Applied to High 87Rb/86Sr Mica

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points Measurement of 86Sr at count rates < 1500 cps can result in statistical bias. Non‐linear signals in analogue detection mode (e.g., Rb) present a challenge for accurately dating high 87Rb/86Sr mica (> 1000). Accounting for these considerations, high 87Rb/86Sr mica are dated here with accuracies of ∼ 1%.

Resolving Micrometre‐Scale Zircon Growth in Silicic Systems by 7 μm LA‐MC‐ICP‐MS U‐Pb Dating: Linking Petrology and Geochronology in Silicic Volcanic and Granitic Rocks from Victoria, Australia

open access: yesGeostandards and Geoanalytical Research, EarlyView.
Key Points 7 μm spot‐diameter LA‐MC‐ICP‐MS analyses yield accurate zircon U‐Pb ages. 1013 Ω amplifier resistors improve low‐signal Pb measurements. Saturn correction protocols minimise down‐hole fractionation effects. We present a systematic evaluation of high spatial‐resolution zircon U‐Pb dating using a Thermo Scientific Neoma multi‐collector ICP‐MS ...

Dentine Regeneration With Calcium Strontium Silicate: In Vitro Odontogenic Differentiation, Antimicrobial Activity, Immunomodulation and In Vivo Pulpotomy in Rat Molars

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Aim This study examined the in vitro and in vivo performance of calcium strontium silicate (CSR) as a novel biomaterial for vital pulp therapy (VPT), assessing its odontogenic differentiation, antibacterial activity, immunomodulation, inflammatory response and dentine regeneration potential compared to calcium silicate (CS) and Mineral ...

Immunophenotypic, Genetic, and Clinical Features Associated With RUNX1 Mutation in Acute Leukemias and Chronic Myeloid Neoplasms

open access: yesInternational Journal of Laboratory Hematology, EarlyView.
ABSTRACT Introduction RUNX1 is a commonly mutated transcriptional regulator of hematopoiesis in acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS). Mutated RUNX1 (mRUNX1) may associate with cross‐lineage immunophenotypic aberrancy, presenting potential complications for blast lineage assignment at diagnosis. Methods Clinical and laboratory

Gender Justice in the Triple Planetary Crisis: A Scoping Review

open access: yesJournal of Advanced Nursing, EarlyView.
ABSTRACT Aim To identify and report how gender justice is conceptualised and discussed in contemporary health literature in relation to the Triple Planetary Crisis of climate change, pollution and biodiversity loss, with a particular focus on the experiences of women and gender‐diverse populations, and the representation of nurses and other healthcare ...
