Surface dose analysis and dosimetric comparison of Halcyon versus Truebeam in breast cancer radiotherapy: An OSL dosimetry study

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Breast cancer is a neoplastic disease with high prevalence among women. Radiotherapy is one of the principal treatment modalities for this disease, but it poses significant challenges. This study aimed to compare and evaluate the technical and dosimetric performance of conventional C‐arm linac systems and a new design, Halcyon, in the ...

Design and validation of a novel dosimetry phantom for motion management audits

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background We present a novel phantom design for conducting end‐to‐end dosimetry audits for respiratory motion management of two anatomical treatment sites. The design enables radiochromic film measurements of the dose administered to the target throughout the respiratory cycle (motion‐included) and the dose delivered to the time‐averaged ...

If it does not help, it might hurt: Pharmacodynamics of a second IVIg course in Guillain–Barré syndrome

Annals of Clinical and Translational Neurology, EarlyView.
Abstract Objectives Intravenous immunoglobulin (IVIg) is an effective treatment for Guillain–Barré syndrome (GBS), but recovery varies between patients. This study aims to evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of a single and a second IVIg dose (SID) in patients with GBS.

EEG Spectral Exponents and Visual Chirp Responses Mirror Anti‐Seizure Medication Load in Refractory Focal Epilepsy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Quantitative markers of cortical excitability may help identify responders to anti‐seizure medications (ASMs). We studied the relationship between ASM load and two electroencephalography (EEG) markers of cortical excitability in people with refractory epilepsy. Methods We included individuals with refractory focal epilepsy undergoing

Light‐Triggered Protease‐Mediated Release of Actin‐Bound Cargo from Synthetic Cells

Advanced Biology, EarlyView.
TEV Prtoease‐mediated Releasable Actin‐binding Protein (TRAP) is a protein‐based platform consisting of a cargo tightly bound to reconstituted actin networks in synthetic cells which can be proteolyticly released from the bound actin, followed by its secretion through membrane translocation mediated by a cell‐penetrating peptide.

Comparison of Microgravity Analogs to Spaceflight in Studies of Plant Growth and Development

Frontiers in Plant Science, 2019
Life on Earth has evolved under the influence of gravity. This force has played an important role in shaping development and morphology from the molecular level to the whole organism. Although aquatic life experiences reduced gravity effects, land plants
