IP3 receptor isoforms differently regulate ER-mitochondrial contacts and local calcium transfer [PDF]

open access: yes, 2019
Contact sites of endoplasmic reticulum (ER) and mitochondria locally convey calcium signals between the IP3 receptors (IP3R) and the mitochondrial calcium uniporter, and are central to cell survival.

Sted, landskab, rum

open access: yesSlagmark - Tidsskrift for idéhistorie, 2018
The article discusses matters concerning place by way of three prose poems byDanish writer Louis Jensen. The readings understand place by way of the neighbouring concepts of landscape and space. They set out from a phenomenological understanding of place, presenting basic insights of this approach (especially using the works of Edward S.

Click Chemistry with Cell-Permeable Fluorophores Expands the Choice of Bioorthogonal Markers for Two-Color Live-Cell STED Nanoscopy

open access: yesCells
STED nanoscopy allows for the direct observation of dynamic processes in living cells and tissues with diffraction-unlimited resolution. Although fluorescent proteins can be used for STED imaging, these labels are often outperformed in photostability by ...

Reactivatable stimulated emission depletion microscopy using fluorescence-recoverable nanographene

open access: yesNature Communications
Stimulated emission depletion (STED) microscopy, a key optical super-resolution imaging method, has extended our ability to view details to resolution levels of tens of nanometers.

Simpler STED setups

open access: yes, 2010
This work discusses rugged technical simplifications for STED nanoscopy and methods related to it (RESOLFT). STED is a type of laser scanning microscopy that uses stimulated emission in order to inhibit spontaneous fluorescence from outer parts of the focal spot.

Optical determination and magnetic manipulation of single nitrogen-vacancy color center in diamond nanocrystal

open access: yes, 2010
The controlled and coherent manipulation of individual quantum systems is a fundamental key for the development of quantum information processing. The nitrogen-vacancy (NV) color center in diamond is a promising system since its photoluminescence is ...
