Characterizing Radiation Effectiveness in Ion-Beam Therapy Part II: Microdosimetric Detectors

Frontiers in Physics, 2020
The specific advantages of ion beams for application in tumor therapy are attributed to their different macroscopic and microscopic energy deposition pattern as compared to conventional photon radiation.

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 ...

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 ...
