Principles of uniapical and biapical radial deformity correction using dome osteotomies and the center of rotation of angulation methodology in dogs.

Objective: To describe the normal anatomic axis of the canine radius in 2 planes (frontal, sagittal), and report the use and efficacy of dome osteotomies for acute correction of canine antebrachial deformities.

Study Design: Retrospective study.

Sample Population: Normal antebrachii (n = 20) radiographs were used as a reference, and 7 dogs with 9 radial angular limb deformities that were corrected by use of dome osteotomies.

15-Deoxy-delta(12,14)-prostaglandin J(2) (15D-PGJ(2)), a peroxisome proliferator activated receptor gamma ligand, reduces tissue leukosequestration and mortality in endotoxic shock.

Peroxisome proliferator-activated receptor-gamma (PPARgamma) is a nuclear receptor that requires ligand activation for transcription. Experimental studies have shown that 15-deoxy-Delta-PGJ2 (15d-PGJ2) is a natural PPARgamma ligand which has potent anti-inflammatory properties. This study was designed to examine the effect and the molecular mechanisms of 15d-PGJ2 on tissue neutrophil infiltration and survival in endotoxic shock.

Peroxisome proliferator-activated receptor-gamma is a new therapeutic target in sepsis and inflammation.

Peroxisome proliferator-activated receptor-gamma (PPARgamma) is a member of the nuclear receptor superfamily and a ligand-activated transcription factor with pleiotropic effects on lipid metabolism, inflammation, and cell proliferation. PPARgamma forms a heterodimer with the retinoid X receptor and upon ligand-activation binds to the PPAR response element in the promoter of genes to allow transcription. The class of insulin-sensitizing drugs known as thiazolidinediones have been identified as specific PPARgamma agonists that have allowed the characterization of many genes regulated by PPARgamma.

Enzyme kinetics for the formation of 3-hydroxyquinine and three new metabolites of quinine in vitro; 3-hydroxylation by CYP3A4 is indeed the major metabolic pathway.

The formation kinetics of 3-hydroxyquinine, 2'-quininone, (10S)-11-dihydroxydihydroquinine, and (10R)-11-dihydroxydihydroquinine were investigated in human liver microsomes and in human recombinant-expressed CYP3A4. The inhibition profile was studied by the use of different concentrations of ketoconazole, troleandomycin, and fluvoxamine. In addition, formation rates of the metabolites were correlated to different enzyme probe activities of CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A4 in microsomes from 20 human livers.

Mesenchymal hamartoma of the liver in the adult: association with distinct clinical features and histological changes.

Mesenchymal hamartoma of the liver (MHL) is an uncommon mass lesion composed of architecturally abnormal bile ducts in an uncommitted myxoid stroma. Most MHL are diagnosed in childhood. More than 50% of cases are seen in the first year of life, although a few cases have been previously reported in adults.
