Selective Cell‐Repellent 3D Scaffold Platform for Proton Radiobiology

open access: yesAdvanced NanoBiomed Research, EarlyView.
A selective cell‐repellent 3D scaffold platform is developed to minimize unwanted 2D cell populations surrounding engineered cell microenvironments. The approach is based on the combination of Lipidure coatings with two‐photon polymerized scaffolds and enables specific characterization of glioblastoma cells’ response to proton irradiation.

Relative affinity constants by electrospray ionization and Fourier transform ion cyclotron resonance mass spectrometry: calmodulin binding to peptide analogs of myosin light chain kinase [PDF]

open access: yes, 2003
Synthetic RS20 peptide and a set of its point-mutated peptide analogs have been used to analyze the interactions between calmodulin (CaM) and the CaM-binding sequence of smooth-muscle myosin light chain kinase both in the presence and the absence of Ca2+.

Advantages of Pulsed Laser Ion Source (LIS) at an Intensity of About 1010 W/cm2 for Heavy‐Ion Injection Into High‐Energy Accelerators

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT At the Laser Plasma Physics laboratories of the University of Messina, an experimental platform for generating and accelerating low‐energy ions (keV) using pulsed lasers and for their potential applications has been put into operation. A Q‐switched Nd:YAG laser produces the beam for the system, operating at 1064 nm.
