Variations in Cell Surfaces of Estrogen Treated Breast Cancer Cells Detected by A Combined Instrument for Far-Field and Near-Field Microscopy

open access: yesAnalytical Cellular Pathology, 2002
The response of single breast cancer cells (cell line T‐47D) to 17β‐estradiol (E2) under different concentrations was studied by using an instrument that allows to combine far‐field light microscopy with high resolution scanning near‐field (AFM/SNOM ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Hierarchical mechanism of amino acid sensing by the T-box riboswitch

open access: yesNature Communications, 2018
Riboswitches on 5′ ends of mRNAs are important for bacterial gene regulation. Here the authors probe the mechanism of a tRNA aminoacylation sensing T-box riboswitch using single-molecule fluorescence microscopy to characterize dynamic solution ...

Automatic classification and segmentation of single-molecule fluorescence time traces with deep learning

open access: yesNature Communications, 2020
Traces from single-molecule fluorescence microscopy (SMFM) experiments exhibit photophysical artifacts that typically make analysis time-consuming. Here, the authors have developed an easily accessible software, AutoSiM, for two distinct applications of ...
