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.

Protocol for quantifying miRNA trafficking across the endosomal membrane

open access: yesFEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

Multiplicity and theremalization time in heavy-ions collisions

open access: yesEPJ Web of Conferences, 2016
We present a concise review of quark-gluon plasma formation in heavy-ions collisions within the holographic approach. In particular, we discuss how to get the total multiplicity in heavy ions collision to fit the recent experimental data. We also discuss

Heavy-Ion Dosimetry

open access: yes, 1980
A comprehensive and accurate definition of the physical characteristics of a radiation field is a necessary, but not sufficient, condition for understanding (and predicting) the probability of observing a biological effect. Part of the difficulty of doing this stems from the fact that very often the biological final state accessible to observation is ...

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

open access: yesAging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Heavy Ion Collisions

open access: yes, 2004
Lattice QCD predicts a phase transition between hadronic matter and a system of deconfined quarks and gluons (the Quark Gluon Plasma) at high energy densities. Recent results from the Brookhaven Relativistic Heavy Ion Collider (RHIC) dedicated to the study of QCD at extreme densities will be discussed and compared to measurements obtained at the CERN ...

Heavy-Ion Linear Accelerator [PDF]

open access: yesReview of Scientific Instruments, 1961
Two linear accelerators have been built for the acceleration of ions in the mass region from helium to argon. The linear accelerators consist of two 70-Mc cavity resonators of the Alvarez design. Ions with a charge to mass ratio e/m≥0.15 times the e/m of a proton are injected into the first cavity of the linear accelerator with a Cockcroft-Walton ...

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 ...

Behavior of Copper, Nickel, Cadmium and Mercury Ions in Anode Chamber of Microbial Fuel Cells

open access: yesInternational Journal of Electrochemical Science, 2018
Microbial fuel cell (MFC) technology is widely used in wastewater treatment, and heavy metal ions play a important role in MFCs. In this paper, we studied the effect of heavy metal ions (copper, nickel, cadmium and mercury) on anode, mainly in voltage ...
