Thermosensitive Nanostructured Coacervates Developed by Mixing ABA‐ and AB‐Block Copolymers and Their Unique Sustained Release of Nano‐Micelles in a Regulated Manner

open access: yesSmall, EarlyView.
Polyion complex micelles composed of blends of ABA and AB block copolymers can form coacervates with a hexagonally packed cylinder nanostructure after heating. The resulting coacervates can release the micelles under physiological conditions in a zero‐order kinetics, possessing cargo proteins.

Advances in deep‐tissue fluorescence imaging through optical clearing: A review

open access: yesVIEW, EarlyView.
Optical clearing refers to techniques that are used to improve the optical transparency of biological tissues. Optical clearing enables imaging of deeper lying tissues as well as 3D volumetric imaging of whole organs. This review examines reports on the integration of optical clearing with advanced fluorescence imaging techniques, with particular ...

Correlative X‐ray imaging and fluorescence microscopy in hydrated environments

open access: yesJournal of Synchrotron Radiation, EarlyView.
We present a combined imaging platform that integrates beamline‐compatible fluorescence microscopy with scanning small‐angle X‐ray scattering to enable sequential multimodal investigations of hydrated cells under near‐native conditions. We apply our method to ordered cytoskeletal structures in different cell types and demonstrate the direct correlation

Mellem det gode sted og intet-sted. Utopi, erindring og migration i det revolutionære Cuba

open access: yes, 2014
Artiklen tager udgangspunkt i utopiens dobbelthed som det gode sted og som det sted, der ikke findes, og bruger denne i en forståelse af diskursive og kulturelle mekanismer der har påvirket den officielle revolutionsdiskurs i Cuba og som tvinger det ...

Multicolor Stimulated Emission Depletion (STED) Microscopy to Generate High-resolution Images of Respiratory Syncytial Virus Particles and Infected Cells

open access: yesBio-Protocol, 2017
Human respiratory syncytial virus (RSV) infection in human lung epithelial A549 cells induces filopodia, cellular protrusions consisting of F-actin, that extend to neighboring uninfected cells (Mehedi et al., 2016). High-resolution imaging via stimulated

Arsenite methyltransferase 3 is required for mitochondrial function and hepatic lipid metabolism

open access: yesThe FEBS Journal, EarlyView.
AS3MT is a protein that helps the body process arsenic, a naturally occurring toxin found in water and soil. We discovered it also helps cells make and use energy properly. Without AS3MT, cells' mitochondria do not work well, leading to fatty liver and reduced activity. Increasing AS3MT in liver cells restores energy and protects against arsenic damage,

GSK3α‐mediated regulation of the RNA demethylase fat mass and obesity‐associated protein (FTO) during murine spermatogenesis

open access: yesThe FEBS Journal, EarlyView.
FTO regulates mRNA stability and translational efficiency through its m6A‐demethylation activity. GSK3 functions as an upstream regulator of FTO, leading to its inhibition via phosphorylation. In male germ cells, FTO activity is kept in check by GSK3α.

Limits to Resolution of CW STED Microscopy

open access: yes, 2013
We report a systematic theoretical and experimental study of the limits to spatial resolution for stimulated emission depletion (STED) superresolution fluorescence microscopy using continuous wave (CW) laser beams.
