Motion Mitigation Techniques for Abdominal and Cardiac MR Imaging

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT MRI of the heart and abdominal organs provides unparalleled soft tissue contrast and quantitative biomarkers, yet remains highly susceptible to physiological motion. Contractions of the myocardium, respiratory excursions, peristalsis, vascular pulsatility, and unpredictable bulk patient movement generate artifacts that impair image quality ...

Arterial spin labelling MRI for assessment of cerebral perfusion in children with moyamoya disease: comparison with dynamic susceptibility contrast MRI [PDF]

, 2018
Introduction: This study seeks to evaluate the diagnostic accuracy of cerebral perfusion imaging with arterial spin labelling (ASL) MR imaging in children with moyamoya disease compared to dynamic susceptibility contrast (DSC) imaging.

Dynamic Margin of Stability During Walking Differs Between End‐Stage Hip, Knee, and Ankle Arthritis

Journal of Orthopaedic Research, EarlyView.
ABSTRACT End‐stage arthritis of the hip, knee, or ankle leads to differential gait adaptations, but the differences in gait stability remain poorly understood. This study examined whether dynamic gait stability differed between patients with end‐stage hip arthritis (HA), knee arthritis (KA) and ankle arthritis (AA), and matched healthy controls (HC ...

Bronchoscopic assessment of airway retention time of aerosolized xylitol

Respiratory Research, 2006
Background Human airway surface liquid (ASL) has abundant antimicrobial peptides whose potency increases as the salt concentration decreases. Xylitol is a 5-carbon sugar that has the ability to lower ASL salt concentration, potentially enhancing innate ...

Enteral and intravenous supplementation of arginine and citrulline fail to prevent necrotizing enterocolitis in preterm neonatal pigs

Journal of Parenteral and Enteral Nutrition, EarlyView.
Abstract Background Necrotizing enterocolitis (NEC) is the most common gastrointestinal emergency in preterm infants with a morality rate that approaches 50%. Arginine has been widely studied in the field of clinical nutrition as a supplement for patients experiencing critical illness because it can be metabolized into nitric oxide, an important agent ...

The Effect of Synthetic Cow Urine on Microorganisms and Their Potential Phosphorus Mining Activity in Rhizosphere and Bulk Soil

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background and aims Soil microbes adapt to varying nutrient inputs by modifying their utilization strategies, with root exudates and animal urine serving as key carbon (C) and nutrient sources in grasslands. Nonetheless, the specific mechanisms by which cow urine and root exudates influence microbial community and resource utilization remain ...

Six-month ground-based water vapour raman lidar measurements over Athens, Greece and system validation [PDF]

, 2007
Water vapour is one of the most important greenhouse gases, since it causes about two third of the natural greenhouse effect of the Earth's atmosphere. To improve the understanding of the role of the water vapour in the atmosphere, extensive water vapour

Arterial Transit Time Mapping Obtained by Pulsed Continuous 3D ASL Imaging with Multiple Post-Label Delay Acquisitions: Comparative Study with PET-CBF in Patients with Chronic Occlusive Cerebrovascular Disease

PLoS ONE, 2016
Arterial transit time (ATT) is most crucial for measuring absolute cerebral blood flow (CBF) by arterial spin labeling (ASL), a noninvasive magnetic resonance (MR) perfusion assessment technique, in patients with chronic occlusive cerebrovascular disease.
