From child and parent needs to supportive interventions for proton therapy without anaesthesia: A qualitative study

Technical Innovations & Patient Support in Radiation Oncology
Introduction: Children must remain still during proton therapy (PT) to ensure precise treatment delivery. For some children, distress, separation from parents, or difficulties coping with the treatment situation necessitate treatment under anaesthesia ...

Chemotherapy for Spinal Cord Intramedullary Pediatric Low‐Grade Glioma—A Systematic Literature Review

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric intramedullary low‐grade gliomas (PIMLGGs) are rare neoplasms that present unique clinical and management challenges. Although surgery remains the primary tool for tissue diagnosis and decompression, complete gross‐total resection is frequently unfeasible due to the infiltrative nature of these lesions.

Hadron particle therapy

Proceedings Particle Accelerator Conference, 2002
Hadron therapy is a maturing field, with strengths and weaknesses that have been clearly identified. For certain tumour types, particles have become the treatment of choice, and hospital-based implementation of these techniques are coming on line. Focused RD effective control requires a wide arsenal of treatment techniques.

Tumour therapy with particle beams [PDF]

AIP Conference Proceedings, 2000
Photons are exponentially attenuated in matter producing high doses close to the surface. Therefore they are not well suited for the treatment of deep seated tumours. Charged particles, in contrast, exhibit a sharp increase of ionisation density close to the end of their range, the so-called Bragg-peak.

Organizing the interface—Plasma membrane architecture and receptor dynamics in virus‐cell interactions

FEBS Letters, EarlyView.
Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...
