Tough and Fast Thermoresponsive Hydrogel Soft Actuators

open access: yesAdvanced Materials Technologies, EarlyView.
This work develops tough, fast‐responding thermoresponsive double‐network hydrogels that combine excellent mechanical strength with rapid actuation. Composed of PNIPAm and ether‐based polyurethane, the hydrogels achieve ≈8 MPa compressive stress and ≈30% contractile stroke within 2 min at 50 °C, enabling temperature‐responsive fluid flow switching for ...

To unwind the biological knots: The DNA/RNA G‐quadruplex resolvase RHAU (DHX36) in development and disease

open access: yesAnimal Models and Experimental Medicine, Volume 5, Issue 6, Page 542-549, December 2022., 2022
Schematic diagram showing RHAU can bind and unwind the G4 “knots” to modulate embryonic development and post‐natal organ function. Deficiency of RHAU gives rise to embryonic lethality, impaired organogenesis and organ dysfunction. RHAU modulates Nkx2‐5 mRNA and Yap1 mRNA at the post‐transcriptional level and facilitates the transcription of c‐Kit and ...

UVC-induced stress granules in mammalian cells. [PDF]

open access: yesPLoS ONE, 2014
Stress granules (SGs) are well characterized cytoplasmic RNA bodies that form under various stress conditions. We have observed that exposure of mammalian cells in culture to low doses of UVC induces the formation of discrete cytoplasmic RNA granules ...

Compacton solutions and (non)integrability for nonlinear evolutionary PDEs associated with a chain of prestressed granules [PDF]

open access: yesarXiv, 2017
We present the results of study of a nonlinear evolutionary PDE (more precisely, a one-parameter family of PDEs) associated with the chain of pre-stressed granules. The PDE in question supports solitary waves of compression and rarefaction (bright and dark compactons) and can be written in Hamiltonian form. We investigate {\em inter alia} integrability

Pulse Dynamics in a Chain of Granules With Friction [PDF]

open access: yes, 2003
We study the dynamics of a pulse in a chain of granules with friction. We present theories for chains of cylindrical granules (Hertz potential with exponent $n=2$) and of granules with other geometries ($n>2$). Our results are supported via numerical simulations for cylindrical and for spherical granules ($n=5/2$).

Comparative proteomics of the two T. brucei PABPs suggests that PABP2 controls bulk mRNA [PDF]

open access: yes, 2018
Poly(A)-binding proteins (PABPs) regulate mRNA fate by controlling stability and translation through interactions with both the poly(A) tail and eIF4F complex.

Deubiquitination and the regulation of stress granule assembly [PDF]

open access: yesCurrent Genetics, 2016
Stress granules (SGs) are evolutionarily conserved ribonucleoprotein (RNP) structures that form in response to a variety of environmental and cellular cues. The presence of these RNP granules has been linked to a number of human diseases, including neurodegenerative disorders like amyotrophic lateral sclerosis (ALS) and spinocerebellar ataxia type 2 ...

Enhanced Performance 3‐D Printed PLA Parts through a Photo‐Initiator Mediated UV‐Curing

open access: yesAdvanced Materials Technologies, EarlyView.
This solvent‐free method enhances 3‐D printed PLA parts by incorporating photo‐initiators during fabrication, followed by up to 3 min UV treatment. This process improves PLA's mechanical properties, including a 64% increase in tensile strength, while addressing weak interlayer bonding and outdoor sensitivity.

Excitation of stellar p-modes by turbulent convection : 2. The Sun [PDF]

open access: yes, 2001
Acoustic power and oscillation amplitudes of radial oscillations computed for a solar model are compared with solar seismic observations. The oscillations are assumed stochastically excited by turbulence. The numerical computations are based upon a theoretical formulation of the power going into solar like oscillation modes as proposed by Samadi et al.

P bodies promote stress granule assembly in Saccharomyces cerevisiae [PDF]

open access: yes
Recent results indicate that nontranslating mRNAs in eukaryotic cells exist in distinct biochemical states that accumulate in P bodies and stress granules, although the nature of interactions between these particles is unknown.
