Professor JiYeon Choi's research lab focuses on improving health outcomes in critical illness and chronic respiratory disease populations, with a strong emphasis on mobility, rehabilitation, and psychosocial support. The lab investigates the impact of early mobility interventions, telerehabilitation platforms, and digital health solutions—particularly for patients recovering from prolonged mechanical ventilation and lung transplant recipients. A key focus is on enhancing physical function, reducing caregiver burden, and addressing health risk behaviors and mental health in both patients and their families. The lab also explores innovative, non-invasive biomarkers such as exhaled nitric oxide for monitoring airway inflammation.

Survivors of critical illness often undergo an extended recovery trajectory. Reduced functional ability is one of several adverse outcomes of prolonged bed rest and mechanical ventilation during critical illness. Skeletal muscle weakness is known to be one of the major phenomena that account for reduced functional ability. Although skeletal muscle weakness is evident after prolonged mechanical ventilation (PMV), few studies have tested the benefits of various types of mobility interventions in t
These results suggest that CHI3L1 inhibitor could be an applicable intervention drug in amyloidogenesis and neuroinflammation, thereby preventing memory dysfunction via inhibition of NF-κB.
Findings suggest two patterns of depressive symptom response in caregivers of critically ill adults on mechanical ventilation from intensive care unit admission to 2 months postintensive care unit discharge. Future studies are necessary to confirm these findings and implications for providing caregiver support.
This study examined the beneficial effects of the n-butanol fraction and rutin extracted from tartary buckwheat (TB) on learning and memory deficits in a mouse model of amyloid β (Aβ)-induced Alzheimer's disease (AD). Learning and memory were assessed using the T-maze, object recognition, and Morris water maze tests. Animals administered Aβ showed impaired cognition and memory, which were alleviated by oral administration of an n-butanol fraction and rutin extracted from TB. Similarly, Aβ-induce
Health risk behaviors of family caregivers are associated with greater perceptions of burden and/or depressive symptoms but not with patients' care needs before admission to the intensive care unit.
Management of airway inflammation requires proper monitoring and treatment to improve long-term outcomes. However, achieving this goal is difficult, as current methods have limitations. Although nitric oxide (NO) was first identified 200 years ago, its physiological importance was not recognized until the early 1980s. Many studies have established the role of NO as an essential messenger molecule in body systems. In addition, studies have demonstrated a significant relationship between changes i
We evaluated the feasibility, safety, system usability, and intervention acceptability of Lung Transplant Go (LTGO), an 8-week in-home exercise intervention for lung transplant recipients using a telerehabilitation platform, and described changes in physical function and physical activity from baseline to post-intervention. The intervention was delivered to lung transplant recipients in their home via the Versatile and Integrated System for TeleRehabilitation (VISYTER). The intervention focused
Oxidative stress and neuroinflammation is implicated in the pathogenesis and development of Alzheimer's disease (AD). Here, we investigated the suppressive possibility of ethanol extract of Nannochloropsis oceanica (N. oceanica) on memory deficiency along with the fundamental mechanisms in lipopolysaccharide (LPS)-treated mice model. Among several extracts of 32 marine microalgae, ethanol extract of N. oceanica showed the most significant inhibitory effect on nitric oxide (NO) generation, NF-κB
