Propagation of measurement uncertainty in measuring remanent flux

, 2020
U ovom radu opisana je Monte Carlo metoda za proračun mjerne nesigurnosti pri mjerenju remanentnog toka. Mjerni rezultati remanentnog toka dobiveni su na dva načina: kao negativna srednja vrijednost magnetskog toka u ustaljenom stanju i kao vrijednost ...

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

Molecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Research on the impact of transformer switching-off on core residual magnetism

Zhejiang dianli
Magnetizing inrush current caused by transformer no-load switching can lead to various issues in power grid operations. Techniques such as phase-controlled switching are effective in mitigating these effects， with the key factor being the measurement of ...

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

Molecular 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 ...

Reduction of residual charge in surface-neutralization-based neutral beams [PDF]

, 1997
Hyperthermal-neutral beams have been proposed as a charge-free alternative to plasmas in select processing steps. Existing prototype sources include three generic types: gas-dynamic, ion-neutral-charge-exchange and ion-surface-neutralization beam sources.

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Electromagnetic zonal flow residual responses

, 2017
The collisionless axisymmetric zonal flow residual calculation for a tokamak plasma is generalized to include electromagnetic perturbations. We formulate and solve the complete initial value zonal flow problem by retaining the fully self-consistent ...

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

Molecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.
