Modelling of Nanoparticle Distribution in a Spherical Tumour during and Following Local Injection
Pharmaceutics, 2022 Radio-sensitizing nanoparticles are a potential method to increase the damage caused to cancerous cells during the course of radiotherapy. The distribution of these particles in a given targeted tumour is a relevant factor in determining the efficacy of ...

FEBS Letters, EarlyView.Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Numerical simulation of the radiation field parameters of different composite anode targets
Fushe yanjiu yu fushe gongyi xuebao, 2023 Bremsstrahlung radiation can produce pulsed X-ray, and the energy spectra and conversion efficiencies of X-ray produced by such radiation are related to the electron beam energy, target material, and structure of this material.

Viscophoretic particle transport
, 2022 Viscosity is a fundamental property of liquids and determines the diffusivity of suspended particles. A gradient in viscosity leads to a gradient in diffusivity, yet it is unknown whether such a gradient can lead to directed transport of particles. In this work, we generate a steep, stable viscosity gradient in a microfluidic channel and image the ...

Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein
FEBS Letters, EarlyView.Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

Einstein's formula for the mass of a moving body assumes the existence of four types of bodies: two types with real values of mass at a speed less than the speed of light and two with different signs and an imaginary value of mass (the speed is greater than the speed of light).

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma
FEBS Letters, EarlyView.Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.

Geophysical Research Letters, 2023 The transport of energetic electrons immersed in Alfvénic turbulence in Earth's outer radiation belt is explored. It is shown how electrons subject to the action of an empirically derived 3‐D spectrum of Alfvénic field fluctuations experience rapid ...
