Functional Analysis of Histidine‐Dependent Self‐Cleaving RNAs Obtained by In Vitro Selection

open access: yesChemBioChem, EarlyView.
Ribozymes can be nucleic acid medicines given their catalytic activity. We attempted to obtain functional RNAs that mimic ribonuclease A catalytic mechanisms. Functional RNAs with high histidine specificity were obtained, suggesting that histidine acts in active structure formation.

EEG–fMRI mapping of asymmetrical delta activity in a patient with refractory epilepsy is concordant with the epileptogenic region determined by intracranial EEG [PDF]

open access: yes, 2006
We studied a patient with refractory focal epilepsy using continuous EEG-correlated fMRI. Seizures were characterized by head turning to the left and clonic jerking of the left arm, suggesting a right frontal epileptogenic region.

Interactions of Neurodegenerative Disease Positron Emission Tomography Imaging Probe Candidates with the C‐Terminus of α‐Synuclein Fibrils

open access: yesChemBioChem, EarlyView.
Binding studies of α‐synuclein (αS) fibril ligands using photo‐crosslinking mass spectrometry and Förster resonance energy transfer show that the multiple system atrophy (MSA)‐selective lead, HY‐215, interacts with the αS C‐terminus, unlike Parkinson's disease (PD)‐selective lead, M503. Thus, often‐ignored interactions with the disordered regions of αS

Kinematics and physical conditions of HI in nearby radio sources. The last survey of the old Westerbork Synthesis Radio Telescope [PDF]

open access: yes, 2017
We present an analysis of the properties of neutral hydrogen (HI) in 248 nearby (0.0230$ mJy and for which optical spectroscopy is available. The observations were carried out with the Westerbork Synthesis Radio Telescope as the last large project before
