Mapping Hsp104 interactions using cross‐linking mass spectrometry

open access: yesFEBS Open Bio, EarlyView.
This study examines how cross‐linking mass spectrometry can be utilized to analyze ATP‐induced conformational changes in Hsp104 and its interactions with substrates. We developed an analytical pipeline to distinguish between intra‐ and inter‐subunit contacts within the hexameric homo‐oligomer and discovered contacts between Hsp104 and a selected ...

Studying the Process of the Internal Combustion Engine Exhaust Gas Purification by an Electric Pulse

open access: yesCommunications, 2022
The article deals with method of purifying the exhaust gases in an automobile muffler or other transport equipment using electrical pulses. Electrical pulses are formed between the two ring electrodes (anode and cathode) installed in series along the gas

Ionization in Atmospheres of Brown Dwarfs and Extrasolar Planets V: Alfvén Ionization [PDF]

open access: yes, 2013
Observations of continuous radio and sporadic X-ray emission from low-mass objects suggest they harbour localized plasmas in their atmospheric environments. For low-mass objects, the degree of thermal ionization is insufficient to qualify the ionized component as a plasma, posing the question: what ionization processes can efficiently produce the ...

Establishment and biological characterization of radioresistant colorectal cancer cell lines

open access: yesFEBS Open Bio, EarlyView.
Under ionizing radiation exposure, radiation‐sensitive cancer cells exhibit oxidative stress and DNA damage, while radiation‐resistant cancer cells exhibit strong antioxidant properties and DNA damage repair. Radiotherapy resistance is a major cause of recurrence and metastasis in colorectal cancer (CRC).

Electron-Impact Ionization of Heavy Atoms Using the Time-Dependent Close-Coupling Method

open access: yesAtoms, 2021
The time-dependent close-coupling method has been recently applied to calculate electron-impact direct ionization cross sections for the Kr, W, and Pb atoms. An overview is presented for these three heavy neutral atom systems.

Shining A Light On Galactic Outflows: Photo-Ionized Outflows [PDF]

open access: yes, 2016
We study the ionization structure of galactic outflows in 37 nearby, star forming galaxies with the Cosmic Origins Spectrograph on the Hubble Space Telescope. We use the O I, Si II, Si III, and Si IV ultraviolet absorption lines to characterize the different ionization states of outflowing gas. We measure the equivalent widths, line widths, and outflow

Modeling of Ionization in a Spherical Surface Ionizer

open access: yesActa Physica Polonica A, 2011
A Monte Carlo method-based model of a hot cavity surface ion source with a spherically shaped ionizer is presented. A numerical code enables studies of ion source efficiency as a function of an extraction voltage, geometry of the ionizer and its temperature, the size of extraction aperture and many other factors.

Possible role of human ribonuclease dicer in the regulation of R loops

open access: yesFEBS Open Bio, EarlyView.
R loops play an important role in regulating key cellular processes such as replication, transcription, centromere stabilization, or control of telomere length. However, the unscheduled accumulation of R loops can cause many diseases, including cancer, and neurodegenerative or inflammatory disorders. Interestingly, accumulating data indicate a possible

Predicting Protein Binding of Drugs Using Abraham Parameters: Effect of Ionization

open access: yesJournal of Mazandaran University of Medical Sciences, 2019
Background and purpose: Protein binding (PB) is an important pharmacokinetic parameter in drug discovery and development. In past years Abraham parameters were used to predict some physicochemical and pharmacokinetic properties of drugs.
