Benchmarking proton RBE models

Physics in Medicine & Biology
Abstract Objective. To biologically optimise proton therapy, models which can accurately predict variations in proton relative biological effectiveness (RBE) are essential. Current phenomenological models show large disagreements in RBE predictions, due to different model assumptions and ...

Comparative Evaluation of Chelator‐Conjugated Peptides for Lead‐Labeled SSTR2‐Targeted Theranostics: Integrated Computational Modeling and Preclinical Validation

Advanced Science, EarlyView.
The study integrates density functional theory with radiochemical and biological validation to compare DOTA‐, PSC‐, and DOTAM‐based chelator‐conjugates for 203Pb/212Pb theranostic applications. Distinct differences in metal coordination, electrostatic properties, conformational flexibility, cellular uptake, biodistribution, and dosimetry are identified

Selective Cell‐Repellent 3D Scaffold Platform for Proton Radiobiology

Advanced 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.

Tooth histotype and enameloid microstructure of Priohybodus arambourgi d'Erasmo, 1960 (Elasmobranchii: Hybodontiformes) from the Late Jurassic of northeastern Brazil

The Anatomical Record, EarlyView.
Abstract Sharks possess varied diets and different prey capture mechanisms. As a result, the group exhibits a significant diversity in dental morphology, also reflecting the internal structures of the teeth. Internal dental anatomy points to the existence of three histotypes in elasmobranch phylogeny: orthodont, osteodont, and pseudoosteodont ...

Fixed- versus Variable-RBE Computations for Intensity Modulated Proton Therapy

, 2019
Purpose: To evaluate how using models of proton therapy that incorporate variable relative biological effectiveness (RBE) versus the current practice of using a fixed RBE of 1.1 affects dosimetric indices on treatment plans for large cohorts of patients ...

Optimization of acid‐catalyzed transesterification of oil derived from mango processing seed waste: a step towards the circular economy

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Energy is the basis for socio‐economic development. The effects of fossil‐based energy sources underscore the urgent need for renewable and cost‐effective alternatives. Biofuels derived from non‐edible and low‐cost feedstocks are a promising alternative.

Intersecting pathways of postpartum depressive symptoms and recurrent binge eating after gestational diabetes: Findings from the LINDA‐Brazil cohort

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective To estimate the prevalence and correlates of recurrent binge eating (RBE) and postpartum depression (PPD), and examine their association among women with prior gestational diabetes mellitus (GDM). Methods This cross‐sectional analysis included 699 women with prior GDM who participated in the postpartum baseline assessment of the ...
