Advances and perspectives in animal models of human hepatitis A virus

Animal Models and Experimental Medicine, EarlyView.
Following HAV infection, humans, non‐human primates, and Ifnar1−/− mice develop characteristic manifestations of hepatitis A, including fecal viral shedding, elevated serum ALT levels, and inflammatory cell infiltration in the liver. In contrast, HAV‐infected human liver chimeric mice exhibit fecal viral shedding but do not develop clinical features of

Stereoselective Biotransformation: Transfer of Learning to Advance Drug Metabolism and Biocatalysis

Angewandte Chemie, EarlyView.
Understanding stereoselective biotransformations has implications for predicting drug disposition and response and may also inspire novel biocatalytic and biomimetic strategies to address challenges in metabolite and API synthesis. ABSTRACT Chirality is an important determinant of drug action, as enantiomers can exhibit markedly different ...

Natural Aging of Biomaterials in Ambient and Physiological Environments

Advanced NanoBiomed Research, EarlyView.
Biomaterials used in biomedical applications can change their physical properties over time, even under ambient and physiological conditions. This review highlights key studies on the natural aging of materials ranging from soft hydrogels to metals and ceramics, emphasizing how time‐dependent changes influence function and performance.

Spatial Detection of Microsphere Polystyrene Plastics and Molecular Remodeling within a Full‐Body Mouse with MALDI Trapped Ion Mobility Mass Spectrometry Imaging

Angewandte Chemie, EarlyView.
Orally administered polystyrene microplastics accumulate in murine tissues and are detected using MALDI‐MSI with TIMS. Lipid profiling reveals decreases in hexosylceramides, sphingomyelins, and ether‐linked phospholipids, indicating altered metabolism.

Beyond PEGylation: Archaeal Lipids for Long‐Circulating Liposomes

Advanced NanoBiomed Research, EarlyView.
Archaeal lipid‐based liposomes, particularly those containing caldarchaeol (GDGT), were found to significantly prolong the circulation time of vancomycin in rats, matching the pharmacokinetic properties of PEGylated systems. These findings suggest archaeal lipids as promising non‐PEG excipients for parenteral applications to minimize drug clearance ...

A Revised Model for Muscarine Biosynthesis Involving Lysine Trimethylation

Angewandte Chemie, EarlyView.
The fatal mushroom toxin l‐(+)‐muscarine is one of the most prominent natural products. We elucidated its biosynthetic origin in the sweating mushroom Collybia rivulosa based on incorporation of stable isotope‐labeled compounds and extensive mass spectrometric analyses.
