Isospin dependence of nucleon emission and radial flow in heavy-ion collisions induced by high energy radioactive beams

open access: yes, 2004
Using an isospin- and momentum-dependent transport model we study the emission of free nucleons and the nuclear radial flow in central heavy-ion collisions induced by high energy radioactive beams.

Berberine–cinnamic acid co‐crystal effect in ameliorating hyperlipidemia might be regulated through the PI3K/AKT/mTOR/SREBP‐1 signaling pathway

open access: yesFEBS Open Bio, EarlyView.
Berberine–cinnamic acid co‐crystal (BBR‐CA) inhibits the phosphorylation of the phosphatidylinositol 3‐kinase (PI3K)/AKT/mammalian target of rapamycin (mTOR) pathway, suppressing the transfer of pre‐sterol regulatory element‐binding proteins‐1 (SREBP‐1) from the endoplasmic reticulum to the nucleus. This results in a decrease in the expression level of

Spin-Isospin Excitations and Muon Capture by Nuclei

open access: yes, 2005
By analyzing the energy-weighted moments of the strength function calculated in RPA and beyond it is shown that the explanation of the effect of missing strength of Gamow-Teller transitions requires that residual interaction produce high-excited $1 ...

Structural and functional analysis of Bacillus sarcosine oxidase and its activity toward cyclic imino acids

open access: yesFEBS Open Bio, EarlyView.
Sarcosine oxidase from Bacillus sp. (SoxB) recognizes l‐proline (l‐Pro), d‐proline (d‐Pro), and l‐thioproline (l‐Tpr) as minor substrates. In this study, we measured their absorption spectra, determined the crystal structures of their enzyme complexes, and performed site‐directed mutagenesis of key residues.

Anion-adaptive crystalline cationic material for 99TcO4 − trapping

open access: yesNature Communications, 2019
Efficient anion recognition and trapping is of great significance for anion-specific separation processes but the design of an anion-adaptive sorbents remains a challenge. Here the authors use a cucurbit[8]uril based soft cationic supramolecular material

Use of 2-color flow cytometry to assess radiation-induced genotoxic damage on CHO-KI cells

open access: yesBrazilian Journal of Radiation Sciences, 2019
The micronucleus assay is an important technique used to evaluate genotoxic damage of chemical or physical agents (as ionizing radiations) on cells, based on quantification of cells bearing micronuclei, which are fragments derived from damage (breakage ...

Understanding Supernova Neutrino Physics using Low-Energy Beta-Beams

open access: yes, 2005
We show that fitting linear combinations of low-energy beta-beam spectra to supernova-neutrino energy-distributions reconstructs the response of a nuclear target to a supernova flux in a very accurate way. This allows one to make direct predictions about

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

open access: yesFEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...
