Discriminative detection of laser-accelerated multi-MeV carbon ions utilizing solid state nuclear track detectors

open access: yesScientific Reports, 2021
A new diagnosis method for the discriminative detection of laser-accelerated multi-MeV carbon ions from background oxygen ions utilizing solid-state nuclear track detectors (SSNTDs) is proposed. The idea is to combine two kinds of SSNTDs having different

Comment on "A Quantum-Mechanical Equivalent-Photon Spectrum for Heavy Ion Physics" [PDF]

open access: yes, 1996
We critically discuss the recently developed quantum-mechanical equivalent photon spectrum by Benesh et al. We point out that the key point, the strong absorption in heavy ion collisions, is not treated adequately.

Heavy Ion Physics at the LHC [PDF]

open access: yesNuclear Physics A, 2005
The ion-ion center of mass energies at the LHC will exceed that at RHIC by nearly a factor of 30, providing exciting opportunities for addressing unique physics issues in a completely new energy domain. Some highlights of this new physics domain are presented here. We briefly describe how these collisions will provide new insights into the high density,

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Heavy-Ion Accelerators

open access: yesAnnual Review of Nuclear Science, 1961
A review is presented of aspects of heavy-ion acceleration, including ion sources, electron stripping, types of accelerators (e,g., d-c high-voltage accelerators, cyclotrons, and linear accelerators), and possibilities for increasing currents and energies. A bibliography containing 68 references is included. (T.F.H.)

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer

open access: yesMolecular Oncology, EarlyView.
Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.

Evidence of medium response to hard probes using correlations of Z bosons with hadrons in heavy ion collisions

open access: yesPhysics Letters B
The first measurement of pseudorapidity and azimuthal angle distributions relative to the momentum vector of a Z boson for low transverse momentum (pT) charged hadrons in lead-lead (PbPb) collisions is presented.

QED Effects in Heavy Few-Electron Ions

open access: yes, 2005
Accurate calculations of the binding energies, the hyperfine splitting, the bound-electron g-factor, and the parity nonconservation effects in heavy few-electron ions are considered. The calculations include the relativistic, quantum electrodynamic (QED),

Neoplastic transformation of mouse C3H 10T1/2 and Syrian hamster embryo cells by heavy ions [PDF]

open access: yes, 1989
C3H 10T1/2 mouse-embryo fibroblasts were used for transformation experiments to study the effectiveness of various heavy ions with energies up to 20 MeV/u and LET values from 170 to 16.000 keV/μm.

Longitudinal circulating tumor DNA profiling in patients with advanced endometrial cancer using an off‐the‐shelf targeted NGS panel

open access: yesMolecular Oncology, EarlyView.
Intratumour heterogeneity complicates precision management of advanced endometrial cancer. Circulating tumor DNA (ctDNA) offers a minimally invasive strategy to capture tumor evolution and therapeutic resistance. Here, we compare tumor‐agnostic NGS with tumor‐informed ddPCR, outlining their relative sensitivity, concordance, and clinical implications ...
