THE RADIAL MOTIONS OF CHARGED PARTICLES IN THE FIELD OF THE CHARGED OBJECT IN GENERAL RELATIVITY AND THEIR CLASSIFICATION

open access: yesOdessa Astronomical Publications, 2007
The radial motions of the charged test particles in the field of a spherically symmetric charged object in general relativity are considered and their classification is built.

Molecular dynamics simulations of positively selected codons in FcγRI reveal novel biochemical binding properties

open access: yesFEBS Open Bio, EarlyView.
Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Forest fires in Europe from July 22-25, 2009 [PDF]

open access: yesArchives of Biological Sciences, 2010
According to the official data of the FAO, in 43% of cases it is unknown how forest fires come about. By analyzing the available data, a hypothesis has been tested according to which such situations are a result of the connection between the burning of ...

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

open access: yesFEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Malformin A1–mediated cytotoxicity in ovarian cancer cells occurs through pyroptosis and autophagy

open access: yesFEBS Open Bio, EarlyView.
This study investigated the effects of the natural compound Malformin A1 (MA1) on the cytoskeleton that regulates cell proliferation and migration. Disruption of the cytoskeleton can impair these processes and promote cancer cell death. MA1 disrupted cytoskeletal organization, induced DNA damage, inflammation, activated autophagy, and pyroptosis ...

Structural studies and functional engineering of NanX: an anhydro‐sialic acid transporter from Escherichia coli

open access: yesFEBS Open Bio, EarlyView.
Biophysical characterisation shows that NanX, a membrane transport protein from the major facilitator superfamily (MFS), forms both monomers and dimers after purification. AlphaFold modelling and substrate docking provide information on residues likely involved in substrate recognition for NanX and another MFS member, NanT.

Frictional cooling of positively charged particles

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2012
One of the focuses of research and development towards the construction of a muon collider is muon beam preparation. Simulation of frictional cooling shows that it can achieve the desired emittance reduction to produce high-luminosity muon beams. We show

On fast charged particles scattering in a thin crystalline undulator

open access: yesPhysics Letters B, 2019
The scattering of fast charged particles in a thin silicon crystalline undulator is considered under conditions when all the particles of the beam undergo above-barrier motion with respect to the bent crystalline atomic planes. The consideration is based

Control of Electrostatic Charge on Particles by Impact Charging [PDF]

open access: yesJournal of the Society of Powder Technology, Japan, 2006
The control of electrostatic charge on particles in gas-solids pipe flow has been studied experimentally and theoretically. Alumina particles of 3.3μm in mass median diameter were dispersed in airflow and pneumatically transported in dilute phase. Five different materials were used for the transport pipes, and the relationships between the particle ...

Purification and preparation of Marchantia polymorpha Auxin Response Factor 2 for phase separation studies

open access: yesFEBS Open Bio, EarlyView.
We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...
