Sulfasalazine Enhances Copper Toxicity in Danio rerio Larvae: Divergent Protective Roles of Deferoxamine and Ferrostatin‐1

Environmental Toxicology, EarlyView.
ABSTRACT Copper is an environmental contaminant capable of disrupting redox homeostasis and impairing antioxidant defenses in aquatic organisms, thereby increasing susceptibility to oxidative stress. The cystine/glutamate antiporter (system xc−) plays a central role in maintaining intracellular glutathione (GSH) levels, a major antioxidant defense ...

New applications of molybdenum (VI) catalyzed oxygen atom transfer reactions

, 2022
The chemistry of dioxomolybdenum coordination complexes has been deeply investigated as a model for molybdoenzyme structure and activity, as well as for non-biological chemical applications. In this work, we present investigation into new applications of

Exposure to Structurally Related Organophosphate Esters Elicits Distinct Metabolomic Perturbations in Daphnia magna

Environmental Toxicology, EarlyView.
ABSTRACT Organophosphate esters (OPEs) are found ubiquitously in the environment and exposure to these chemicals has induced behavioral, developmental, and morphological impairments in several model organisms. Yet there is still a lack of understanding of how sub‐lethal exposure disrupts organism function at the molecular‐level, especially for Daphnia ...

Increased anergic B cells and decreased antibody‐secreting cells during romiplostim treatment in patients with immune thrombocytopenia

British Journal of Haematology, EarlyView.
Summary Patients with immune thrombocytopenia (ITP) exhibit substantial heterogeneity in treatment responses. Approximately 30%–50% of patients maintain remission after discontinuation of thrombopoietin receptor agonists (TPO‐RA), suggesting immunomodulatory effects beyond enhanced thrombopoiesis.

Predicted microbiome‐associated metabolic pathways are linked to immune checkpoint modulation in chronic lymphocytic leukaemia

British Journal of Haematology, EarlyView.
Summary Microbial metabolites are key regulators of host immunity, yet their functional impact in chronic lymphocytic leukaemia (CLL) remains unclear. Following up on our earlier observations of microbiome dysbiosis in CLL, we performed predictive metabolic profiling based on 16S ribosomal RNA (rRNA) sequencing of oral and stool samples collected from ...

Creep and dynamic abnormal grain growth of commercial-purity molybdenum

, 2005
textIn this experimental investigation, the tensile creep behavior of commercial-purity molybdenum sheet at temperatures between 1300°C and 1700°C is critically evaluated, based upon experimental creep testing and microstructural characterizations.

S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea

The FEBS Journal, EarlyView.
S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.

ALOX15 mediates thrombin‐induced myristoylation, trafficking, and interaction of protease‐activated receptors, leading to platelet activation and hemostasis

The FEBS Journal, EarlyView.
The role of PARs in platelet function is fairly known; however, the underlying mechanisms are not fully understood. We report that thrombin myristoylates PAR4 in mouse platelets and PAR1 and PAR4 in human platelets, facilitating their membrane transport and interaction, leading to PAR3/4 heterodimers in mice and PAR1/4 heterodimers in humans.

Molybdenum-Catalyzed Asymmetric Hydrogenation of Fused Arenes and Heteroarenes

The synthesis of enantioenriched molybdenum precatalysts for the asymmetric hydrogenation of substituted quinolines and naphthalenes is described. Three classes of pincer ligands with chiral substituents were evaluated as supporting ligands in the ...
