Determination of 23 Elements in Biological Samples by Wavelength Dispersion X-ray Fluorescence Spectrometry with High Pressure Pressed Powder Pellet Preparation

open access: yesYankuang ceshi, 2014
In the determination of biological samples by X-ray Fluorescence Spectrometry, sample powder pellets pressed by traditional sample preparation technique at 220-440 MPa are not compact and smooth, so the sample room of X-ray Fluorescence Spectrometry ...

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

open access: yesFEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

APPLICATION OF MONTE-CARLO INTEGRATION TO 3-DIMENSIONAL FLUORESCENCE SPECTROMETRY

open access: yes, 1995
In this paper, the sensitivity of three-dimensional fluorescence spectrometry (TDFS) is studied by using the total fluorescence intensity, calculated by Monte Carlo integration, instead of conventional single-point intensity.

Evaluating the effect of γ‐oryzanol on MASLD pathology using a medaka fish model

open access: yesFEBS Open Bio, EarlyView.
This study explores a liver disease called MASLD, which is increasing worldwide and can lead to serious damage. Researchers used medaka fish instead of rodents to test a food compound, γ‐oryzanol. Fish fed this compound had less liver fat and healthier gut bacteria.

Three-dimensional derivative - Fluorescence spectrometry and its application to simultaneous determination of polyaromatic hydrocarbons by detecting total fluorescence intensity

open access: yes, 1996
Three-dimensional derivative - fluorescence spectrometry is first developed and applied to the simultaneous determination of polyaromatic hydrocarbons, naphthalene, pyrene and perylene, by measuring total fluorescence intensity.

Fluorescence Quenching of Alpha-Fetoprotein by Gold Nanoparticles: Effect of Dielectric Shell on Non-Radiative Decay

open access: yesNanoscale Research Letters, 2010
Fluorescence quenching spectrometry was applied to study the interactions between gold colloidal nanoparticles and alpha-fetoprotein (AFP). Experimental results show that the gold nanoparticles can quench the fluorescence emission of adsorbed AFP ...

Adenosine triphosphate as a modulator of protein interactions and stability

open access: yesFEBS Open Bio, EarlyView.
ATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

open access: yesFEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...
