Transient absorption spectra.

open access: yes, 2012
Top: Steady-state absorption spectra of the CO complex of the Tf-trHb (red line) and the ferrous 5c-protein (black line). The protein concentration is 36 µM (2 mm path length cell).

Epigenetic silencing of the liver‐specific lncRNA LUNAR promotes liver cancer progression via NOTCH activation

open access: yesMolecular Oncology, EarlyView.
LUNAR is a liver‐specific long noncoding RNA (lncRNA) that is highly expressed in normal liver but becomes epigenetically silenced in hepatocellular carcinoma through promoter hypermethylation. Loss of LUNAR is associated with NOTCH activation, epithelial–mesenchymal transition, and metastasis, whereas restoring LUNAR restrains metastatic progression ...

Long-lived, pulse-induced transient absorption in ( ) solid solutions: the case of three intrinsic defect sites for electron localization with strong coupling

open access: yesNew Journal of Physics
Femto-/nanosecond pulse-induced, red and near-infrared absorption is studied in $\text{LiNb}_{1-x}\text{Ta}_x\text{O}_3$ ( $0\unicode{x2A7D} x \unicode{x2A7D}1$ , LNT) solid solutions with the aim of studying transient optical nonlinearities associated ...

Stability and Thermal Conductivity Characteristics of Nanofluids (H2O/CH3OH + NaCl + Al2O3 Nanoparticles) for CO2 Absorption Application [PDF]

open access: yes, 2012
In this study, the nanofluids are produced by dispersing Al2O3 nanoparticles in the H2O/CH3OH binary mixtures using an ultrasonic equipment. Solid Sodium Chlorides (NaCl) with a fixed mass fraction are dissolved in the binary mixture for CO2 absorption ...

Transient Vibrational Echo versus Transient Absorption Spectroscopy: A Direct Experimental and Theoretical Comparison

open access: yes, 2010
Transient dispersed vibrational echo (DVE) spectroscopy is a practical alternative to transient-absorption spectroscopy because it affords increased sensitivity as well as greater signal-to-noise ratio without the need to detect a reference spectrum ...

Luminescence and Transient Absorption of CdWO$\text{}_{4}$ Crystals [PDF]

open access: yes, 1999
Luminescence and transient absorption of the oxygen-deficient CdWO$\text{}_{4}$ crystal were studied. The electron transitions from the excited state of the luminescence center to some higher energy state are responsible for the transient absorption ...

A role for eIF5A in translational control of stress‐inducible proteins in multiple myeloma cell lines

open access: yesMolecular Oncology, EarlyView.
Loss of eIF5A rewires thapsigargin‐mediated endoplasmic reticulum stress responses in multiple myeloma cells by selective translation of mRNA transcripts, consequently dampening thapsigargin‐induced unfolded protein response (UPR) activation and shifting the balance from induction of apoptosis toward cell survival and proliferation.

USP7 inhibits FOXO1 activity in chronic lymphocytic leukaemia cells enhancing cell survival

open access: yesMolecular Oncology, EarlyView.
CLL cells rely on BCR‐mediated signalling for survival and proliferation in part through suppression of FOXO1. FOXO1 activity is regulated by a plethora of post‐translational modifications including phosphorylation and ubiquitination. We demonstrated that dual inhibition of BCR signalling and the deubiquitinase USP7 activates FOXO1, modulating its ...

Broadband single-shot transient absorption spectroscopy

open access: yesOptics Express, 2020
The duration of transient absorption spectroscopy measurements typically limits the types of systems for which the excited state dynamics can be measured. We present a single-shot transient absorption (SSTA) instrument with a spatially encoded 60 ps time delay range and a 100 nm spectral range that is capable of acquiring a transient spectrum in 20 s ...

Transient absorption of vibrationally excited ice Ih [PDF]

open access: yesThe Journal of Chemical Physics, 2008
The ultrafast dynamics of HDO:D2O ice Ih at 180K is studied by midinfrared ultrafast pump-probe spectroscopy. The vibrational relaxation of HDO:D2O ice is observed to proceed via an intermediate state, which has a blueshifted absorption spectrum.
