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

Methionine Regulates Antitumour Function of CD8+ T Cells Through Polyamine Synthesis

Immunology, EarlyView.
Methionine restriction in vitro enhances CD8+ T cell effector function by suppressing polyamine synthesis and progressively induces the co‐expression of PD‐1 and TIM‐3. Consistently, sustained dietary methionine restriction diminishes the efficacy of adoptive T cell therapy (ACT) and promotes the expression of terminal exhaustion‐associated markers ...

Marine migration influences mercury accumulation in anadromous Arctic char (Salvelinus alpinus)

Journal of Fish Biology, EarlyView.
Abstract Mercury (Hg) is a globally distributed toxic metal present in northern natural environments that biomagnifies in food webs and bioaccumulates in apex predator fish, such as Arctic char (Salvelinus alpinus)—an iteroparous species with a circumpolar distribution. Arctic char exhibit a variety of life history types, with the migrating, anadromous

(Ultra)high‐Pressure Metamorphism in Sedimentary Versus Basaltic Rocks: Insights From a Variscan Mélange in the South Carpathians

Journal of Metamorphic Geology, EarlyView.
ABSTRACT Reconstructing the pressure–temperature–time (P–T–t) evolution of (ultra)high‐pressure rocks is essential for constraining subduction and collisional dynamics. Subduction zones are often investigated using basic eclogites, whereas nonbasic high‐pressure rocks remain comparatively understudied, potentially hindering a comprehensive ...

Selective glomerular hypofiltration is associated with glucometabolic disturbances in the general population

Journal of Internal Medicine, EarlyView.
Abstract Background Discordance between cystatin C‐ and creatinine‐based estimated glomerular filtration rate (eGFR) has been linked to adverse outcomes. A low eGFRcys/eGFRcr‐ratio, conceptualized as selective glomerular hypofiltration syndrome (SGHS), has been hypothesized to reflect early metabolic kidney vulnerability, although non‐glomerular ...
