Moisture-induced elastic constants of poplar

open access: yesMaderas: Ciencia y Tecnología
Twelve elastic constants of Populus × canadensis, previously unavailable in the literature, were determined using ultrasonic testing.Samples were conditioned at a temperature of 20 °C ± 1 °C and 45 %, 65 %, and 85 % relative humidity.

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

open access: yesFEBS 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 ...

Effects of IGFBP4 deficiency on human preadipocyte proliferation and differentiation through the IGF1R/AKT pathway

open access: yesFEBS Open Bio, EarlyView.
IGFBP4 knockdown (KD) impairs preadipocyte proliferation and is associated with IGF1R protein downregulation and attenuated AKT phosphorylation. The mechanisms by which IGFBP4 KD influences the IGF1R/AKT signaling pathway involve newly synthesized proteins and lysosomal degradation pathways. Created in BioRender.

SEMANTIC CONSTANTS AND VERIABLES OF HUMAN MIND IN IDEOGRAPHIC DICTIONARIES

open access: yes, 2017
Dictionaries which systematize lexis into certain thematic or semantic classes are widely used in teaching Russian as a foreign language. In Russian schools, such dictionaries can be used to build and expand learners’ vocabulary and to enable them to ...

Effect of terahertz irradiation on DNA damage repair in living cells

open access: yesFEBS Open Bio, EarlyView.
We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.

Entropic constraint on cosmic variation of Planck mass and the Boltzmann constant

open access: yesResults in Physics
In cosmology, cosmic variations of fundamental constraints are constrained by the arrow of time of astrophysical black holes, given the Bekenstein–Hawking entropy S∼kBM/mp2 of their event horizon parameterized by black hole mass M and the Planck mass mp ...

KDAC6 alters cell morphology and motility through positive and negative modulation of F‐actin distribution

open access: yesFEBS Open Bio, EarlyView.
KDAC6 has been associated with cell motility and actin structures, but specific domain contributions are not established. The two catalytic domains have differential effects on motility and F‐actin regulation, affecting cortical F‐actin density, motility, stress fibers, and cell spreading.

Numerical and experimental validation of variation of power transformers' thermal time constants with load factor

open access: yes, 2017
Thermal time constants (TTC) of a thermal dynamic model reflect the change rate of temperature, which are affected by many factors such as load current, oil temperature, etc.
