Very High-Energy Electron Therapy Toward Clinical Implementation

Cancers
The use of very high energy electron (VHEE) beams, with energies between 50 and 400 MeV, has drawn considerable interest in radiotherapy due to their deep tissue penetration, sharp beam edges, and low sensitivity to tissue density. VHEE beams can be precisely steered with magnetic components, positioning VHEE therapy as a cost-effective option between ...

Very High Energy Electrons (50 – 250 MeV) and Radiation Therapy

Technology in Cancer Research & Treatment, 2002
High energy electron beams in the range 150–250 MeV are investigated to evaluate their feasibility for radiotherapy. Monte Carlo simulation results from PENELOPE code are used to determine lateral spread and penetration of these beams. It is shown that dose distribution of electron beams compare favorably with photon beams.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Additional acceleration of solar-wind particles in current sheets of the heliosphere [PDF]

, 2015
Particles of fast solar wind in the vicinity of the heliospheric current sheet (HCS) or in a front of interplanetary coronal mass ejections (ICMEs) often reveal very peculiar energy or velocity profiles, density distributions with double or triple peaks,

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

FEBS 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.
