Log file‐based quality assurance method for respiratory gating system

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background As medical linear accelerator technology advances, enabling higher dose rate deliveries, hypofractionation regimens has increased. This necessitates respiratory gating systems that synchronize radiation delivery with tumor position, requiring simple rigorous quality assurance (QA) to ensure treatment accuracy and patient safety ...

Associations of Cerebrospinal Fluid Orexin‐A, Alzheimer Disease Biomarkers, and Cognitive Performance

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACTObjectiveCerebrospinal fluid (CSF) orexin‐A has been suggested to be a biomarker of Alzheimer disease (AD). In both cognitively unimpaired healthy older adults and individuals with symptomatic AD, CSF orexin‐A is positively associated with CSF Aβ42, p‐tau181, and total tau (t‐tau) concentrations.

Immunosuppressive Drugs in Early Systemic Sclerosis and Prevention of Damage Accrual

Arthritis Care &Research, EarlyView.
Objective Organ damage in patients with systemic sclerosis (SSc) in individual organs such as the lungs may be prevented by receiving immunosuppressive drugs (ISs). A new measure of global organ damage, the Scleroderma Clinical Trials Consortium Damage Index (SCTC‐DI), has allowed us to investigate whether receiving ISs may reduce global organ damage ...

Sex‐Related Differences in Efficacy and Safety Outcomes in Axial Spondyloarthritis Randomized Clinical Trials: A Systematic Literature Review and Meta‐Analysis

Arthritis Care &Research, EarlyView.
Objective We aimed to assess differences in baseline characteristics, efficacy, and safety of advanced therapies between male and female patients with axial spondyloarthritis (axSpA) in randomized controlled trials (RCTs). Methods We conducted a systematic literature search for RCTs assessing the efficacy of advanced therapies in patients with axSpA ...

Preventive Effect of Metformin in Radiation‐Induced Xerostomia

Advanced Biology, EarlyView.
Head and neck cancer patients who received radiotherapy complain of severe dry mouth due to damage to the salivary glands. Metformin is an antidiabetic drug, but its radio‐protective effect has been reported. It is confirmed that metformin protects the salivary glands from radiation and provides evidence for the use of metformin in cancer treatment in ...

Coacervates Composed of Low‐Molecular‐Weight Compounds– Molecular Design, Stimuli Responsiveness, Confined Reaction

Advanced Biology, EarlyView.
Coacervation driven by liquid‐liquid phase separation (LLPS) of biopolymers has garnered increasing attention in biology since this leads to the formation of membraneless organelles capable of performing essential yet largely unknown functions. This review highlights recent advances in coacervates (artificial condensates) composed of low‐molecular ...
