Inflammation induced by snake venoms optimizes envenomation

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic illustrating mechanisms underlying direct vascular absorption and subsequent movement of venom toxins into the tissues consequent to snakebite. A, snakebite into prey deposits venom toxins into the tissue interstitium, with the venom then causing acute inflammation primarily in venules.

Feasibility and Safety of High‐Dose Proton Re‐Irradiation in Recurrent Pediatric Central Nervous System Tumors: A Single‐Institution Retrospective Study

Pediatric Blood &Cancer, Volume 73, Issue 7, July 2026.
ABSTRACT Purpose Pediatric central nervous system (CNS) tumors often recur despite multimodality therapy. Although re‐irradiation (re‐RT) has historically been limited by concerns for severe late toxicities, modern techniques have renewed interest in this approach. Proton therapy provides dosimetric advantages that may enable curative re‐treatment with

On evaluation methods for post-processing of PTV

Journal of the Visualization Society of Japan, 2000
Recently, many researchers propose interpolation methods for PTV (Particle Tracking Velocimetry) data because the spatial distribution of physical quantities can not be directly obtained by PTV. These interpolation methods use mathematical or physical logic-based algorithms, and their accuracy are evaluated by several physical quantities.

Explainable machine learning for patient‐specific quality assurance in intensity‐modulated radiotherapy based on anatomical structures

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background Patient‐specific quality assurance (PSQA) plays a pivotal role in intensity‐modulated radiotherapy (IMRT) to ensure accurate dose delivery. However, conventional measurement‐based PSQA approaches are labor‐intensive and provide limited insight into the underlying factors contributing to variations in gamma passing rates (GPRs ...

Latent density discrepancies in commercial lung‐equivalent inserts and their clinical dosimetric impact

Journal of Applied Clinical Medical Physics, Volume 27, Issue 7, July 2026.
Abstract Background Accurate heterogeneity correction in high‐precision radiotherapy relies on precise computed tomography (CT) number‐to‐density conversion via the Hounsfield unit look‐up table (HLUT). While physical properties of tissue‐equivalent materials are generally assumed consistent with manufacturer specifications, an independent audit ...

Mass spectrometry imaging of N‐linked glycans: Fundamentals and recent advances

Mass Spectrometry Reviews, Volume 45, Issue 4, Page 599-623, July/August 2026.
Abstract With implications in several medical conditions, N‐linked glycosylation is one of the most important posttranslation modifications present in all living organisms. Due to their nontemplate synthesis, glycan structures are extraordinarily complex and require multiple analytical techniques for complete structural elucidation.
