Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

open access: yesFEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.

Spectroscopic constants and potential-energy derivatives for diatomic molecules of alkali halides [PDF]

open access: yes, 1989
The potential-energy derivatives are derived directly from the experimental values of the spectroscopic constants for diatomic alkali halides. It is found that these derivatives are useful in predicting more accurately the values of the higher order ...

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 ...

Spectroscopic Determination of Acidity Constants of Some Monoazo Resorcinol Derivatives [PDF]

open access: yes, 2008
WOS: 000255655900001The acidity constants, as pK(a) values, of six monoazo resorcinol derivatives were determined by the UV-visible spectroscopic technique at 25 degrees C (+/- 0.1 degrees C).

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Spectroscopic Constants and Line Positions for TiO Singlet States [PDF]

open access: yes, 2018
consistent set of spectroscopic constants for the a1Δ,d1Σ+,b1Π,c1Φ, and f1Δ states of 48Ti16O has been determined from analysis of the b1Π–a1Δ,b1Π–d1Σ+,c1Φ–a1Δ, and f1Δ–a1Δ systems. Three Fourier transform emission spectra have been used for the analysis.

Binding of cadmium to soil humic acid as a function of carboxyl group content

open access: yesMacedonian Journal of Chemistry and Chemical Engineering, 2010
The binding of Cd(II) to soil humic acid (HA) at pH 6.5 and in 0.1 mol/L KNO3 ionic medium, was studied by potentiometric titration with a cadmium ion selective electrode.
