AI Article Synopsis
- The first commercial MRI-guided radiation therapy system features a split 0.35-T MRI scanner and three cobalt-60 radiation heads on a ring gantry.
- The system allows for simultaneous MRI imaging and radiation therapy, sharing a common isocenter for enhanced precision.
- Washington University began treating patients with this advanced technology in January 2014, utilizing its on-couch adaptive planning and control system for effective treatments.
Article Abstract
A description of the first commercially available magnetic resonance imaging (MRI)-guided radiation therapy (RT) system is provided. The system consists of a split 0.35-T MR scanner straddling 3 (60)Co heads mounted on a ring gantry, each head equipped with independent doubly focused multileaf collimators. The MR and RT systems share a common isocenter, enabling simultaneous and continuous MRI during RT delivery. An on-couch adaptive RT treatment-planning system and integrated MRI-guided RT control system allow for rapid adaptive planning and beam delivery control based on the visualization of soft tissues. Treatment of patients with this system commenced at Washington University in January 2014.

Background: Solid organ transplantation (SOT) is vital for end-stage organ failure but faces challenges like organ shortage and rejection. Artificial intelligence (AI) offers potential to improve outcomes through better matching, success prediction, and automation. However, the evolution of AI in SOT research remains underexplored.

Deficient trip recovery kinematics have been implicated in many trip-induced falls. Three key requisites for successful trip recovery include limiting trunk flexion, maintaining adequate hip height to enable repeated stepping, and completing recovery steps to extend the base of support. The purpose of this study was to evaluate sternum drop as a new measure of trip recovery performance.

Article Synopsis
- Parkinson's disease (PD) is characterized by the loss of dopamine neurons and is influenced by α-synuclein aggregation and neuroinflammation, with microglia playing a key role.
- Previous research identified mesencephalic astrocyte-derived neurotrophic factor (MANF) as a potential inhibitor of α-synuclein accumulation and neuroinflammation, though its molecular mechanisms were not fully understood.
- This study found that reducing MANF expression increased inflammation (TNF-α), while exogenous MANF promoted autophagy, reduced α-synuclein levels, and inhibited neuroinflammation, suggesting that MANF could be a therapeutic target for PD through its role in autophagy.

Monitoring of kidney function traditionally relies on plasma creatinine concentrations, necessitating invasive blood draws. Non-invasively obtainable biofluids, such as sweat and saliva, present a patient-friendly alternative with potential for continuous monitoring. This study focusses on developing and validating a novel Liquid Chromatography- tandem Mass Spectrometry (LC-MS/MS) assay as a reference test for measuring low creatinine concentrations in sweat and saliva.
