Findings support previous views that dissection may produce valve-like artifacts (eg, bisection S63845 of an obstructing diaphragm) and that deformation of an otherwise normal urethra may result in megacystis. The designation “”posterior urethral valves” should not be used as a generic expression of urethral obstruction unless actual
valves are demonstrated.”
“A growing body of evidence indicates that the incidence of atherosclerosis is increased in subjects with periodontitis a chronic infection of the oral cavity. This article summarizes the evidence that suggests periodontitis shifts the lipoprotein profile to be more proatherogenic. LDL-C is elevated in periodontitis and most studies indicate that triglyceride levels
are also increased. By contrast, antiatherogenic HDL tends to be low in periodontitis. Periodontal therapy tends to shift lipoprotein levels to a healthier profile and also reduces subclinical indices of atherosclerosis. In summary, periodontal disease alters lipoprotein metabolism in ways that could promote atherosclerosis and cardiovascular 11-deoxojervine disease.”
“The aim of this study was to evaluate the removal of butter cholesterol through three complexation methods with beta-cyclodextrin (beta-CD): co-precipitation, kneading, and physical mixture. Photoacoustic spectroscopy (PAS) was used to evaluate the inclusion complex cholesterol in beta-CD. The co-precipitation method was the most appropriate for removal of butter cholesterol. The composition in fatty acids was not affected by the adopted process. The standardization of the extraction technique of butter cholesterol for its quantification was efficient. The comparison between three quantification methods, enzymatic, high-performance liquid chromatography, and gas chromatography, showed no significant differences. PAS allowed to evaluate the extraction Citarinostat price of butter cholesterol, and showed that the amount of beta-CD used can be reduced. The results showed that the use of this technique opens new
prospects to confirm the formation of the inclusion complex, the “”guest-beta-CD”". (C) 2010 Elsevier Ltd. All rights reserved.”
“Mitochondrial DNA (mtDNA) depletion syndrome is a relatively novel cause of hepatic dysfunction in the pediatric population. It is caused by mutations in either mtDNA or nuclear DNA (nDNA) that result in a quantitative reduction in mtDNA and, in turn, dysfunctional oxidative phosphorylation. In infants, it results in the hepatocerebral phenotype, characterized by hyperbilirubinemia, coagulopathy, lactic acidosis, hypoglycemia, lethargy, encephalopathy, developmental delay, and hypotonia. Three infants diagnosed with mtDNA depletion syndrome at The Children’s Hospital of Philadelphia were identified, and their clinical presentation, disease course, and histologic and ultrastructural features of liver samples (pre- and postmortem) were characterized.
