Direct observation of exciton–exciton interactions
Nature Communications, 2018 Some photo-physical processes in multichromophore systems might get triggered only if two excitations are present. Here, the authors introduce exciton–exciton-interaction 2D spectroscopy, which is a non-linear optical method that can selectively track ...

Systematic Direct Observation of Clinical Skills in the Clinical Year
MedEdPORTAL, 2014 Introduction Direct observation of clinical skills is vital to medical student development. However, direct observation of medical students by faculty is often sporadic, undocumented, and unstandardized.

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

The Potential of Computer-Assisted Direct Observation Apps [PDF]
, 2015 Direct behavior observation, i.e., without first creating a video recording, is a challenging, one-shot task. The behavior has to be coded accurately during the situation itself.

On the Contribution of Direct Child Observation to Psycho-Analysis [PDF]
, 2016 In this essay, Winnicott develops further the theme of his paper ‘The Observation of Infants in a Set Situation’ (1941) and re-emphasises the importance of direct observation to psychoanalysis.

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.
