Artemia salina Toxicity Assay: Standardization in a 24‐Well Microplate
Environmental Toxicology, EarlyView.ABSTRACT Bioassays with Artemia sp. are widely used in aquatic, environmental, and human toxicology as an initial tool to investigate the toxicity of plant extracts, isolated compounds, drugs, and products of natural or synthetic origin. These assays allow for the estimation of the median lethal concentration (LC50) and guide subsequent studies in ...

Hyperlipidaemia in youth with type 1 diabetes: Are current guidelines clinically useful?
Diabetic Medicine, EarlyView.Abstract Aims Dyslipidaemia in youth with type 1 diabetes mellitus (T1D) is emerging as an important modifiable cardiovascular risk factor. International consensus guidelines to screen this entity have evolved over time. To further evaluate this in an Australian context, we investigated adherence to such guidelines over the course of patient care ...

Geostandards and Geoanalytical Research, EarlyView.Key Points Triple oxygen isotope ratios of two primary (VSMOW, SLAP) and twelve secondary water isotopic reference materials were precisely measured using BrF5 fluorination‐IRMS. The measured Δ'17OVSMOW value for SLAP (34 ± 6 per meg) demonstrates that VSMOW‐SLAP normalisation ensures interlaboratory comparability, but introduces systematic offsets for

Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology
Geostandards and Geoanalytical Research, EarlyView.Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference
