Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Separation and hydrogenation of nitrate ions by micro-scale capacitive-faradaic fuel cells (CFFCs)

open access: yesElectrochemistry Communications, 2020
A new electrochemical process is proposed for a zero-discharge removal of nitrate ions from water. The process utilizes micro-scale capacitive-faradaic fuel cells (CFFC) made of activated carbon particles loaded with a Pt-Cu catalyst capable of oxygen ...

Disposable electrochemical sensor for the detection of lead(II) ions in the natural water

open access: yesInternational Journal of Electrochemical Science, 2021
The leaching of metal ions from the mines may result in pollution of the surrounding waters. In this work, we propose a composite material that combines porous carbon and graphene (G-C), which shows a very high sensitivity to lead ions.

The pyruvate generator is a common phenomenon in mitochondria from different rat and mouse brain regions

open access: yesFEBS Letters, EarlyView.
The pyruvate generator, which causes activation of respiration by extra‐mitochondrial Ca2+, is also present and functional in rat brainstem mitochondria, as it is in other brain regions. This finding is confirmed by experiments with a fully reconstituted malate–aspartate shuttle (MAS).

Deciphering the Acute Cellular Phosphoproteome Response to Irradiation with X-rays, Protons and Carbon Ions*

open access: yesMolecular & Cellular Proteomics, 2017
Radiotherapy is a cornerstone of cancer therapy. The recently established particle therapy with raster-scanning protons and carbon ions landmarks a new era in the field of high-precision cancer medicine.

Influence of the Inert Gas Pressure on Intrinsic Stress in Diamond-Like Coating Deposited From Vacuum Arc Carbon Plasma

open access: yesEast European Journal of Physics, 2022
Within the framework of the model of the nonlocal thermoelastic peak of low-energy ion, the formation of intrinsic stress in a carbon coating deposited from the vacuum arc plasma in the argon atmosphere is theoretically studied.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Ion Beam Analyses of Carbon Nanotubes [PDF]

open access: yesThe Journal of Physical Chemistry B, 2005
The utility of ion beam analysis (IBA) techniques to quantitatively determine impurities in carbon nanotubes (CNTs) over a wide range of atomic numbers is demonstrated. Such techniques have not previously been used to monitor impurities and their effects in this unique material. Despite the difficulty in mounting the samples (which generally are formed

Mini-TEPC Microdosimetric Study of Carbon Ion Therapeutic Beams at CNAO

open access: yesEPJ Web of Conferences, 2017
Mono-energetic carbon ion scanning beams of 195.2 MeV/u at the Italian National Centre for Oncological Hadrontherapy (CNAO) have been used to study the microdosimetric features of an “active” carbon ion beam used in hadrontherapy.

Heterozygous loss‐of‐function alleles associate the conserved 3′‐5′ exoribonuclease EXOSC10 with hypersensitivity to the anticancer drug 5‐fluorouracil

open access: yesMolecular Oncology, EarlyView.
EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.
