Proton accelerators

, 2012
Until the 1990s proton therapy was performed in nuclear physics laboratories that were equipped with a particle accelerator. Typically an (isochronous) cyclotron or a synchrocyclotron was available, and in most cases the medical program had to compete ...

Hypervision Proton Surgery: The Future Direction of Proton Therapy

iNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

Predictive Value of Nutrition Indices in Advanced Hepatocellular Carcinoma Patients Treated With Lenvatinib

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT The prognostic nutritional index (PNI) and geriatric nutritional risk index (GNRI) are simple markers that reflect immune and nutritional status. This retrospective study evaluated their prognostic significance in 276 patients with advanced hepatocellular carcinoma (HCC) who received first‐line lenvatinib. PNI and GNRI were calculated based on

Is Proton Therapy Superior to Gamma Knife Radiosurgery for Sporadic Vestibular Schwannoma?

The Laryngoscope, EarlyView.
With changing practice patterns, radiation therapy for vestibular schwannomas has become an increasingly utilized treatment modality with high tumor control rates. Gamma‐Knife radiosurgery remains a well‐established and readily accessible option with good rates for tumor control, cranial nerve preservation, and hearing outcomes.

Ion Activation Methods for Top‐Down Proteomics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)
