Using Polymerization-Induced Self-Assembly in Orthogonally-Reactive Dispersants to Design Tough Nanostructured Materials: Application to Epoxy Networks. [PDF]

Angew Chem Int Ed Engl
Polymerization‐induced self‐assembly (PISA) can be efficiently performed in orthogonally reactive dispersants such as epoxides (DGEBA or ECC) to generate a range of reactive block copolymer dispersions displaying different morphologies. Subsequent polymerization of the epoxide dispersant (through epoxy‐amine reaction or cationic photopolymerization ...

An arbuscular mycorrhiza from the 407-million-year-old Windyfield Chert identified through advanced fluorescence and Raman imaging. [PDF]

New Phytol
Summary Mycorrhizal associations between fungi and plants are a fundamental aspect of terrestrial ecosystems. Mycorrhizas occur in c. 85% of extant plants, yet their geological record remains sparse. Rare fossil evidence from early terrestrial environments offers crucial insights into these ancient symbioses, but visualizing fossil fungi at the ...

Correlated X-Ray and Electron Microscopies of a Single Biphasic GaAs Nanowire. [PDF]

Small Methods
Nano‐focused scanning X‐ray diffraction microscopy at a synchrotron light source, combined with transmission electron microscopy, reveals a clear correlation between the nanoscale distribution of cubic and hexagonal segments in a GaAs nanowire with subtle variations in inter‐reticular spacing, bending, and twisting.

LINC01116, a hypoxia-lncRNA marker of pathological lymphangiogenesis and poor prognosis in lung adenocarcinoma. [PDF]

Mol Oncol
The LINC01116 long noncoding RNA is induced by hypoxia and associated with poor prognosis and high recurrence rates in two cohorts of lung adenocarcinoma patients. Here, we demonstrate that besides its expression in cancer cells, LINC01116 is markedly expressed in lymphatic endothelial cells of the tumor stroma in which it participates in hypoxia ...

Oligodendroglial primary cilium heterogeneity during development and demyelination/remyelination

Frontiers in Cellular Neuroscience, 2022
The primary cilium (PC) has emerged as an indispensable cellular antenna essential for signal transduction of important cell signaling pathways. The rapid acquisition of knowledge about PC biology has raised attention to PC as a therapeutic target in ...

Ultrastructural study of sperm cells in Acanthocolpidae: the case of Stephanostomum murielae and Stephanostomoides tenuis (Digenea) [PDF]

PeerJ, 2015
The mature spermatozoa of Stephanostomum murielae and Stephanostomoides tenuis are described by transmission electron microscopy. They present several ultrastructural features previously reported in other digeneans. Their spermatozoa possess two axonemes
