IMPACT: The importance of SCFE is on the rise due to consumers’ preferences for ‘natural’ as opposed to synthetic substances and, impending regulations for environmental protection, safety, nutritive and toxicity levels.
APPLICATIONS: Newer applications of SCFs include separation and purification of chemicals, cleaning, coating, particle formation, textile dyeing, aerogel drying, reactions
with separation and food preservation. Some fundamental aspects of SCFs, various processing technologies with SCFs, and a few newer potential applications are presented in this article. (C) 2008 Society of Chemical Industry”
“Background: Left ventricular noncompaction (LVNC) describes deep trabeculations in the left ventricular (LV) endocardium and STI571 a thinned epicardium. LVNC is seen both as a primary cardiomyopathy JAK inhibitor and as a secondary finding in other syndromes affecting the myocardium such as neuromuscular disorders. The objective of this study is to define the prevalence of LVNC in the Duchenne Muscular Dystrophy (DMD) population and characterize its relationship to global LV function.
Methods:
Cardiac magnetic resonance (CMR) was used to assess ventricular morphology and function in 151 subjects: DMD with ejection fraction (EF) > 55% (n = 66), DMD with EF < 55% (n = 30), primary LVNC (n = 15) and normal controls (n = 40). The non-compacted to compacted (NC/C) ratio was measured click here in each of the 16 standard myocardial segments. LVNC
was defined as a diastolic NC/C ratio > 2.3 for any segment.
Results: LVNC criteria were met by 27/96 DMD patients (prevalence of 28%): 11 had an EF > 55% (prevalence of 16.7%), and 16 had an EF < 55% (prevalence of 53.3%). The median maximum NC/C ratio was 1.8 for DMD with EF > 55%, 2.46 for DMD with EF < 55%, 1.54 for the normal subjects, and 3.69 for primary LVNC patients. Longitudinal data for 78 of the DMD boys demonstrated a mean rate of change in NC/C ratio per year of +0.36.
Conclusion: The high prevalence of LVNC in DMD is associated with decreased LV systolic function that develops over time and may represent muscular degeneration versus compensatory remodeling.”
“The usefulness of ultrasound (US) for improving steps in analytical chemistry has been widely demonstrated in the past decade. One of the recent applications of US is to facilitate formation of emulsion for dramatic enhancement of the contact between surfaces of two immiscible phases. The effect is to enhance mass transfer between phases (liquid-liquid extraction) in miniaturized systems and to promote leaching of polar and non-polar components (solid-liquid extraction).
We discuss potential uses with special emphasis on the achievements and the weak points of the present research.
