Fiber association and network formation in PLA/lignocellulosic fiber composites. [PDF]

, 2013
PLA composites were prepared in an internal mixer with a lignocellulosic fiber having relatively large aspect ratio. Fiber content changed between 0 and 60 vol% and the homogenized material was compression molded to 1 mm thick plates.

Hyperosmotic stress‐induced redistribution of pre‐mRNA cleavage factor I subunits is associated with shifts in alternative polyadenylation

FEBS Open Bio, EarlyView.
Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

Experimental investigation of thickness effects in the manufacture of thick-section composite structures using liquid thermoplastic resin

Advanced Manufacturing: Polymer & Composites Science
Thick-section composites (10–100 mm) are increasingly used in structurally demanding applications. Growing interest in sustainable alternatives has driven the development of recyclable, room-temperature-processable liquid thermoplastic resins to replace ...

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

The Tribological and Sealing Properties of PFA Composites

International Journal of Polymer Science, 2018
The polytetrafluoroethylene (PTFE) and perfluoroalkoxyperfluoropropyl vinyl ether (PFA) composites were prepared using carbon fiber (CF) and glass fiber (GF) as fillers.

Roughness profile and surface roughness after toothbrushing and degree of conversion of bulk-fill resins [PDF]

Brazilian Oral Research
The aim of this study was to assess roughness profile and surface roughness after simulated toothbrushing cycles, as well as the degree of conversion (DC) of bulk-fill resin composites at different depths.

Treatment with KCL‐286, a first‐in‐class retinoic acid receptor‐β (RARβ) agonist, ameliorates neuronal DNA damage and inflammation in a mouse model of Alzheimer's disease

FEBS Open Bio, EarlyView.
Repair of neuronal DNA damage in Alzheimer's disease by KCL‐286. (A) Amyloid‐β oligomers and plaques impair neuronal DNA repair pathways, leading to DNA double‐strand breaks and glial activation. (B) KCL‐286 activates RARβ/RXR signalling via retinoic acid response elements (RAREs), associated with increased BRCA1 expression, enhanced DNA repair and ...

Achieving superior mechanical performance in one-part geopolymer composites through innovative hybrid fiber systems of recycled steel and PVA fibers

Journal of Materials Research and Technology
Fiber-Reinforced Geopolymer Composites (FRGCs) typically use mono-fiber reinforcement, often overlooking the potential benefits of hybrid fibers. This article examines the effects of different PVA fibers (thick and thin) and steel fibers (straight ...
