Generation of a Novel In Vitro Model to Study Endothelial Dysfunction from Atherothrombotic Specimens

Cardiovascular Drugs and Therapy - Endothelial dysfunction is central to the pathogenesis of acute coronary syndrome. The study of diseased endothelium is very challenging due to inherent...

Recommendations for probiotic use--2008

Recommendations for the clinical use of probiotics were published after a Yale University Workshop in 2005. A similar workshop was held in 2007, and the recommendations were updated and extended into other areas. The recommendations are graded into an "A," "B," "C" or no category based on the expert's opinion and review by the workshop participants. An "A" recommendation is made for acute childhood diarrhea, prevention of antibiotic-associated diarrhea, preventing and maintaining remission in pouchitis, and in an immune response for the treatment and prevention of atopic eczema associated with cow's milk allergy. The group maintained several "B" recommendations in other areas of treating inflammatory bowel disease and irritable bowel syndrome. Although there are significant studies in the "B" group, most "B" recommendations did not reach an "A" level because of some negative studies or a limited number of studies. Many reports in the "C" recommendations were significant but fell short of receiving stronger ratings because of the size of reported patient studies, and also the factors that limited categories to the "B" rating.     

Nitric oxide sera levels as an inflammatory marker in asthma.

BACKGROUND: Nitric oxide is an important regulator of various biological activities in human physiology, and it has been studied in the physiopathology of asthma, especially in exhaled air. OBJECTIVE: We studied the presence of NO in sera of patients with distinct degrees of asthma severity in order to determine a parameter of diagnosis and control of efficacious treatment. METHODS: We determined the presence of NO based upon the Griess reaction in the sera of 124 donors--34 controls and 90 asthmatic subjects. RESULTS: Asthmatic patients presented higher levels of nitric oxide in peripheral blood (56.54 +/- 33.37) compared to the control group (3.06 +/- 4.48). A statistically significant difference (p < 0.0001) between the nitric oxide sera levels from the two groups was demonstrated. CONCLUSION: This study demonstrates that nitric oxide sera levels can be used as an additional inflammatory marker in asthma, especially as an auxiliary diagnostic method in children where NO exhaled air analysis is difficult.     

Eisenmenger's syndrome: current management

Eisenmenger's syndrome describes the elevation of pulmonary arterial pressure to the systemic level caused by increased pulmonary vascular resistance with reversal or bi-directional shunting through a large intracardiac or extracardiac congenital heart defect. This article reviews the natural history and pathophysiology of Eisenmenger's syndrome untreated and medical and surgical treatment options presently available. Although there is no cure for this condition at present, recent advances in management have improved the quality of life for many patients with Eisenmenger's syndrome.
