Acute Effects of Smoking and Vaping on Markers of Vascular Function via Quantitative MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background E‐cigarettes contribute to endothelial dysfunction, a known cause of systemic atherosclerotic disease that cannot be adequately characterized by a single physiological parameter measured at a single vascular bed. Purpose/Hypothesis Quantify and compare acute effects of smoking or vaping with tobacco cigarettes (t‐cigs), nicotinized ...

Phytotoxicity Assessment of Ashes Generated From Household Combustion of Conventional Fuels, Mixed Fuels, and Municipal Waste

Land Degradation &Development, EarlyView.
ABSTRACT The main aim of the study was to assess the toxicity of ash generated in household furnaces through the combustion of materials most commonly burned in individual households. The toxicity tests were conducted using plant bioassays with cress (Lepidium sativum), mustard (Sinapis) and sorghum (Sorghum) seeds.

Image‐Derived Volumetry During Forced Expiration Using a 3D Fermat Looped, Orthogonally Encoded Trajectory

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To enable MRI‐based nongated 3D depiction of forced expiration with both high spatio‐temporal resolution and fidelity of lung dynamics. Methods An undersampled 3D Fermat looped, orthogonally encoded trajectory (FLORET) was optimized for nonsegmented dynamic acquisitions during forced expiration and a corresponding model‐based ...

Correlating Pulmonary Hemodynamics With HP 129Xe Dissolved‐Phase MRSI in a Controlled Porcine Intervention Study

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Pulmonary hypertension is related to a 1‐year mortality ranging from < 5% to > 20% in low‐ and high‐risk groups. Right heart catheterization is the diagnostic gold standard, associated with a 1.1% rate of severe adverse events, posing the need for a non‐invasive diagnostic tool.

Effects of airway tone and volume history on maximal expiratory flow in asthma

, 1987
We assessed the difference between isovolumic maximal expiratory flows (Vmax) using maneuvers begun at mid-lung volumes, so-called partial expiratory flow-volume curves (P), vs.

Incomplete Spoiling Correction for 3D T1$$ {T}_1 $$ Mapping

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Assess the impact of incomplete spoiling and spatial saturation on T1$$ {T}_1 $$ mapping using the variable flip angle (VFA) spoiled gradient recalled echo sequence (SPGR). Develop a correction for incomplete spoiling that results in an accurate estimate of T1$$ {T}_1 $$, essential for quantitative MRI applications.

Emergencies in Amyotrophic Lateral Sclerosis

Muscle &Nerve, EarlyView.
ABSTRACT Emergencies are frequent in people living with amyotrophic lateral sclerosis (pALS), especially as the disease progresses, and can necessitate urgent evaluation and intervention. Progressive weakness in ALS inevitably increases fall risk, making discussion of fall prevention strategies integral to caring for pALS.

Low birth weight for gestation and airway function in infancy: exploring the fetal origins hypothesis [PDF]

, 2004
Background: Poor fetal growth has been associated with impaired airway function in adult life, but evidence linking birth weight and airway function in early childhood is sparse.

A Pilot and Feasibility Study of a Four‐Stage Neurological Staging Framework in Pediatric Tracheal Extubation During Anesthesia Emergence

Pediatric Anesthesia, EarlyView.
ABSTRACT Background Postoperative tracheal extubation is a particularly high‐risk period in pediatric anesthesia. Because emergence from anesthesia is a complex and complicated process, determining the optimal timing for safe tracheal extubation remains challenging.
