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

open access: yesJournal 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 ...

Effects of Single and Multiple Dose Tiotropium/Olodaterol in Chronic Obstructive Pulmonary Disease on Alveolar Gas Exchange Measured by Hyperpolarized 129Xe MRI

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Long‐acting muscarinic antagonists/long‐acting beta adrenoreceptor agonists lead to lung deflation and improved microvascular perfusion in hyperinflated chronic obstructive pulmonary disease (COPD), but with an unclear time course. Purpose To investigate the effect of inhalation of tiotropium/olodaterol (TIO/OLO) on MRI measures of ...

Liberation Through Narration: A Novel Humanistic Framework to Address Body Dissatisfaction

open access: yesThe Journal of Humanistic Counseling, EarlyView.
ABSTRACT Though body dissatisfaction is nuanced and pervasive, the magnitude of body dissatisfaction is undercut by essentialist conceptualizations of the body and medicalized metrics of wellness tied to disordered eating. Hence, there is a need for a contextualized and sustaining framework to address and promote healing from body dissatisfaction ...

Smoking effects on root coverage outcomes between 3 and 12 months: A prospective cohort study

open access: yesJournal of Periodontology, EarlyView.
Abstract Background This study aimed to evaluate the impact of smoking on root coverage outcomes, comparing healing responses at 3–12 months following coronally advanced flap with a connective tissue graft (CAF+CTG). Methods This prospective cohort study included 27 participants (13 smokers, 14 non‐smokers) who required root coverage for a single Cairo

Chemical Ionization Mass Spectrometry: Fundamental Principles, Diverse Applications, and the Latest Technological Frontiers

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The review examines the evolution of chemical ionization mass spectrometry (CI‐MS), a technique developed in 1966 by Field and Munson. CI is a soft‐ionization method that produces more intense molecular ions with less fragmentation than electron ionization (EI).

Breathe, Eat, Talk: Three Essential Ingredients to Quality‐of‐Life Outcomes in Movement Disorders

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Breathing, eating, and talking (BET) impairments are common yet frequently underrecognized features of movement disorders. Deficits in respiration, swallowing, voice, and speech may emerge early in the course of a disease, adversely affecting safety, participation, and quality of life.

Motion‐Robust Approach for 4D Cardiac Cine Using 2D Real‐Time Acquisitions and Slice‐to‐Volume Reconstruction

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose 4D cardiac cine is a powerful tool for comprehensive cardiac function assessment; however, current methods rely on regular breathing and are sensitive to bulk motion and arrhythmia. We aim to develop a 4D cardiac cine approach that requires no patient cooperation and is robust to irregular breathing, bulk motion, and cardiac arrhythmia.
