CTFFIND4: Fast and accurate defocus estimation from electron micrographs
bioRxiv, 2015 CTFFIND is a widely-used program for the estimation of objective lens defocus parameters from transmission electron micrographs. Defocus parameters are estimated by fitting a model of the microscope’s contrast transfer function (CTF) to an image’s ...

The scanning electron microscope in microbiology and diagnosis of infectious disease
Scientific Reports, 2016 Despite being an excellent tool for investigating ultrastructure, scanning electron microscopy (SEM) is less frequently used than transmission electron microscopy for microbes such as viruses or bacteria.

Chondrogenic potential of canine articular cartilage derived cells (cACCs)
Open Life Sciences, 2016 In the present paper, the potential of canine articular cartilage-derived cells (cACCs) for chondrogenic differentiation was evaluated. The effectiveness of cACCs’ lineage commitment was analyzed after 14 days of culture in chondorgenic and non ...

Scanning Electron Microscope: Advantages and Disadvantages in Imaging Components
, 2017 An account of the early history of SEM has been presented by McMullan (1988 and 2006) Although Max Knoll produced a photo with a 50 mm object-field-width showing channeling contrast by the use of an electron beam scanner, (Knoll, 1935) it was Manfred von

A Scanning Electron Microscope for Ultracold Atoms
, 2006 We propose a new technique for the detection of single atoms in ultracold quantum gases. The technique is based on scanning electron microscopy and employs the electron impact ionization of trapped atoms with a focussed electron probe.

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Cell wall target fragment discovery using a low‐cost, minimal fragment library
FEBS Letters, EarlyView.LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.
