Purification, Structural Characterization, and Anticancer Activity of the Polysaccharide From Sea Red Rice Bran

open access: yesFood Frontiers, EarlyView.
Sea red rice bran polysaccharides were separated and purified by DEAE‐52 column chromatography, yielding three components: SRBP‐I, II, and III. Moreover, all three are pentosan‐type polysaccharides predominantly composed of mannose. Among them, SRBP‐I demonstrated the most potent inhibitory effect on HeLa cells. Further investigation indicated that the

Synergy effect of alpha particles by using natural boron in proton therapy: Computational verification

open access: yesAIP Advances, 2019
The use of boron (11B) is recently being investigated to be applied in proton therapy as a proton boron fusion dose enhancement agent. Alpha particles are emitted from the p + 11B → 3α fusion (PBF) reaction analogous to the 10B(n,7Li)α capture (BNC ...

Nasopharyngeal Endoscopic Resection Extended to the Internal Carotid Artery (Type 4): Technical Notes, Indications, and Outcomes

open access: yesHead &Neck, EarlyView.
ABSTRACT Background Endoscopic surgical approaches for nasopharyngeal malignancies, including recurrent nasopharyngeal carcinoma (rNPC) and nasopharyngeal salivary gland tumors (NSGT), have seen significant development over the last decades. Our groups have expanded the classification of nasopharyngeal endoscopic resections (NER) from type 1 to 3 to ...

Proton pencil minibeam irradiation of an in-vivo mouse ear model spares healthy tissue dependent on beam size.

open access: yesPLoS ONE, 2019
Proton radiotherapy using minibeams of sub-millimeter dimensions reduces side effects in comparison to conventional proton therapy due to spatial fractionation.

Hypofractionated Spot Scanning Proton Therapy for Head and Neck Mucosal Melanoma: A Retrospective Analysis With Quality‐of‐Life Outcome

open access: yesHead &Neck, EarlyView.
ABSTRACT Objective To evaluate clinical outcomes and quality of life (QOL) following hypofractionated spot‐scanning proton therapy (SSPT) for head and neck malignant mucosal melanoma (HNMM). Methods This retrospective study included 39 patients treated with SSPT (60–64 Gy[RBE] in 15–16 fractions) between 2013 and 2023.

Disparities in Proton Radiation Utilization for HPV‐Associated Oropharyngeal Cancer Following TORS

open access: yesHead &Neck, EarlyView.
ABSTRACT Introduction Racial, socioeconomic, and geographic disparities in receipt of proton radiation have been reported. Whether disparities exist for oropharyngeal squamous cell carcinoma (OPSCC) is not well studied. Methods Patients with HPV‐associated OPSCC treated with transoral robotic surgery (TORS) and adjuvant radiation from 2016 to 2023 were

Measurement of the energy spectrum of secondary neutrons in a proton therapy environment

open access: yesCurrent Directions in Biomedical Engineering, 2017
Measurement of the energy spectrum of secondary neutrons were carried out at the OncoRay Proton Therapy facility in Dresden, following an approach originating in neutron metrology which is well suited for both the characterization of secondary neutron ...
