Post-radiolabeling thioether oxidation to enhance the bioorthogonal reactivity of ¹⁸F-tetrazines

open access: yes, 2023
Radiolabeled 1,2,4,5-tetrazines are powerful heterocyclic agents for bioorthogonal PET imaging due to their fast cycloaddition with trans-cyclooctenes. However, fluorine-18 radiolabeling of highly reactive tetrazines is often not feasible due to limited ...

Essential lipid autacoids rewire mitochondrial energy efficiency in metabolic dysfunction‐associated fatty liver disease

open access: yesHepatology, EarlyView., 2022
Increased liver content of DHA‐derived small lipid autacoids (i.e resolvin D1 and maresin 1) associates with enhanced mitochondrial oxidative phosphorylation, fatty acid β‐oxidation and bioenergetic metabolic flux. These features provide hepatic protection from steatotic, pro‐inflammatory and fibrogenic insults.

Mitochondrial stress in advanced fibrosis and cirrhosis associated with chronic hepatitis B, chronic hepatitis C, or nonalcoholic steatohepatitis

open access: yesHepatology, EarlyView., 2022
Adaptive mitochondrial mechanisms allow mitochondrial resilience and prevent the worsening of fibrosis, while deregulation of these mechanisms promotes the progression from no/minimal‐mild (F0‐F2) fibrosis to advanced fibrosis and cirrhosis (F3‐F4). Abstract Background and Aims Hepatitis B virus (HBV) infection causes oxidative stress (OS) and alters ...

A Proof-of-Concept Study on the Therapeutic Potential of Au Nanoparticles Radiolabeled with the Alpha-Emitter Actinium-225

open access: yesPharmaceutics, 2020
Actinium-225 (225Ac) is receiving increased attention for its application in targeted radionuclide therapy, due to the short range of its emitted alpha particles in conjunction with their high linear energy transfer, which lead to the eradication of ...

Radiolabeling Method for Lyophilizate for Dry Powder Inhalation Formulations

open access: yes, 2022
Human lung deposition data is non-mandatory for drug approval but very useful for the development of orally inhaled drug products. Lung deposition of inhaled drugs can be quantified by radionuclide imaging, for which one of the first considerations is ...

From Host to Phage Metabolism: Hot Tales of Phage T4’s Takeover of E. coli

open access: yesViruses, 2018
The mechanisms by which bacteriophage T4 converts the metabolism of its E. coli host to one dedicated to progeny phage production was the subject of decades of intense research in many labs from the 1950s through the 1980s.
