Recent progress in field-directed assembly of colloids in an evaporating droplet

Materials Today Bio
Evaporation-driven self-assembly of colloidal particles in a sessile drop can construct simple structures in various scenarios. However, the non-equilibrium self-assembly process, dominated by internal capillary flow and solute- or thermal-induced ...

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

Molecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

Molecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

The investigation and characterisation of colourless glass from forensic and archaeological contexts using multiple interdisiplinary analytical techniques [PDF]

, 2011
The techniques used to analyse glass in forensics and archaeology differ: forensic analysis relies almost completely on Refractive Index, whereas archaeology uses compositional analyses.

Studying pigments on painted plaster in Minoan, Roman and Early Byzantine Crete. A multi-analytical technique approach [PDF]

, 2011
Wall paintings spanning two millennia of Cretan painting history and technology were analysed in an effort to determine similarities and evolutions of painting materials and technology. A multi-technique approach was employed that combined the use of (a)

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

Molecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated
