“The denture bases nanocomposites were prepared by adding organic montormollontrite(OMMT) into poly(methyl methacrylate) matrix. The resulting composites were characterized by XRD, TEM, and ISTRON 3365 flexural strength testing systems. One-way selleck chemicals analysis of variance and Tukey’s test were used to compare the difference in flexural strength and flexural modulus. The results showed the formation of exfoliated-intercalated and intercalated denture base nanocmposite when the content of OMMT was 3 wt % and 5 wt % in the powder of denture base resin, respectively. The maximum ultimate flexural strength was observed in denture
base nanocomposite containing 3 wt % of OMMT and flexural strength decreased with further increases of OMMT content. Tariquidar mouse The flexural modulus of denture base nanocomposite increased continually with OMMT content increasing from 1 wt % to 10 wt %. Significant difference in both flexural strength and flexural modulus was observed between the nanocomposites with 3 wt % OMMT and controls (n = 5, P < 0.05). (C) 2009 Wiley Periodicals, Inc.

“Case Description-A 10-year-old Lipizzaner stallion was evaluated over the course of 1.5 years because of intermittent, recurrent colic.
Clinical Findings-The horse was initially treated medically for gastric ulcers; dietary RSL3 ic50 changes were made, and a deworming protocol was instituted, without resolution of colic episodes. Subsequently, the horse underwent exploratory celiotomy and a large colon volvulus was identified with diffuse colonic wall thickening. A pelvic flexure biopsy sample was submitted for histologic examination, which revealed lymphocytic (CD3-positiveT cells) myenteric ganglionitis (MG). The horse developed a cecal impaction after surgery, which did not resolve, despite aggressive medical management; subsequently a complete cecal bypass
was performed. Cecal and colonic wall biopsy samples were evaluated histologically and confirmed the diagnosis of MG. After surgery, the horse developed a large colon impaction, which initially responded to aggressive medical treatment, and the horse was discharged.
Treatment and Outcome-Despite rigorous feed restrictions and prokinetic and corticosteroid treatment, the horse continued to have signs of colic and was euthanized 3 weeks after discharge from the hospital because of a recurrent large colon impaction. Intestinal biopsy samples obtained at the time of death revealed chronic changes in intramural ganglia consistent with generalized MG.
Clinical Relevance-MG is a rare disease in horses, causing gastrointestinal motility dysfunction and signs of colic, which is challenging to diagnose and treat successfully.
