The Role Of Scavenger Receptor Class B Type I-Regulated Inducible Glucocorticoids In Sepsis, Junting Ai
The Role Of Scavenger Receptor Class B Type I-Regulated Inducible Glucocorticoids In Sepsis, Junting Ai
Theses and Dissertations--Nutritional Sciences
Sepsis claims over 215,000 lives in the US annually. Inducible glucocorticoids (iGC) is produced during sepsis. However, the precise effects of iGC in sepsis remain unclear due to a lack of appropriate animal models. Glucocorticoid (GC) insufficiency is associated with a marked increase in mortality and occurs in 60% of severe septic patients. Yet the conclusion of GC therapy on septic patients is still controversial.
Scavenger receptor class B type I (SR-BI) in the adrenal mediates the selective uptake of cholesteryl ester from lipoproteins for GC synthesis. SR-BI-/- mice completely lack iGC during sepsis and are highly susceptible to septic …

IMPORTANCE: Comorbidities are common in COPD, but quantifying their burden is difficult. Currently there is a COPD-specific comorbidity index to predict mortality and another to predict general quality of life. We sought to develop and validate a COPD-specific comorbidity score that reflects comorbidity burden on patient-centered outcomes.
MATERIALS AND METHODS: Using the COPDGene study (GOLD II-IV COPD), we developed comorbidity scores to describe patient-centered outcomes employing three techniques: 1) simple count, 2) weighted score, and 3) weighted score based upon statistical selection procedure. We tested associations, area under the Curve (AUC) and calibration statistics to validate scores internally with outcomes …

BACKGROUND: An important step toward understanding the biological mechanisms underlying a complex disease is a refined understanding of its clinical heterogeneity. Relating clinical and molecular differences may allow us to define more specific subtypes of patients that respond differently to therapeutic interventions.
RESULTS: We developed a novel unbiased method called diVIsive Shuffling Approach (VIStA) that identifies subgroups of patients by maximizing the difference in their gene expression patterns. We tested our algorithm on 140 subjects with Chronic Obstructive Pulmonary Disease (COPD) and found four distinct, biologically and clinically meaningful combinations of clinical characteristics that are associated with large gene expression …
