The dosimetric advantages of particle therapy lead to significantly reduced integral dose to normal tissues, making it an attractive treatment option for body sites such as the thorax. With reduced normal tissue dose comes the potential for dose escalation, toxicity reduction, or hypofractionation. While proton and heavy ion therapy have been used extensively for NSCLC, there are challenges in planning and delivery compared with X-ray-based radiation therapy. Particularly, range uncertainties compounded by breathing motion have to be considered. This article summarizes the current state of particle therapy for NSCLC with a specific focus on the impact of dosimetric uncertainties in planning and delivery.

Purpose: Real‑time magnetic resonance-guided radiation therapy (MRgRT) integrates MRI with a linear accelerator (Linac) for gating and adaptive radiotherapy, which requires robust image‑quality assurance over a large field of view (FOV). Specialized phantoms capable of accommodating this extensive FOV are therefore essential. This study compares the performance of four commercial MRI phantoms on a 0.

Immune-mediated necrotizing myopathy (IMNM) is an emerging and severe form of myositis. Most patients experience persistent muscle weakness or recurrent attacks within their lifetime. The previous view suggests that autoimmune and complement activation play a key role in muscle damage, and aggressive immunotherapy may benefit patients.

Glioblastoma (GBM), the most prevalent and lethal primary malignancy of the central nervous system, remains refractory to conventional photon radiotherapy due to inherent limitations in dose distribution. Although carbon ion radiotherapy offers distinct advantages, including its characteristic Bragg peak deposition and superior relative biological effectiveness, its clinical application is constrained by high costs and increased toxicity. This study explores the radiobiological interactions underlying a mixed carbon ion-photon irradiation regimen, a promising strategy in advanced particle therapy.

Objectives: To develop the orphan drug benznidazole (BNZ) in orally disintegrating tablets, for the neglected disease American Trypanosomiasis (Chagas disease) therapy. Although children are highly affected by this disease, there are no specific commercial pharmaceutical preparations for this age group in Argentina and in many other countries.
Methods: In the production process, co-milling in a ball mill was applied to enhance dissolution rates, followed by direct compression.

Turmeric (Curcuma longa) exhibits anti-obesity properties, yet its low water solubility limits bioavailability. In this study, a water-dispersible turmeric rhizome extract (WDTE) was developed using nano-dispersion technology with maltodextrin as a wall material and characterized by UPLC-QTOF-MS, dynamic light scattering, and zeta potential analysis. The WDTE contained 10 identified metabolites, including five diarylheptanoids such as curcumin, demethoxycurcumin, and bisdemethoxycurcumin, with curcumin quantified at 7.
