Indicadores bioquímicos séricos e do líquido peritoneal de equinos submetidos à obstrução intestinal

Twenty-four horses were distributed into four different groups, instrumented control (GI), duodenum obstruction (GII), ileum obstruction (GIII) and large colon obstruction (GIV). Serum and peritoneal fluid analysis of aspartate aminotransferase, creatine kinase, lactate dehydrogenase, alkaline phosphatase, inorganic phosphorus and lactate were measured. Samples were collected one hour before the surgical procedure (T0); 3 hours after the obstruction (T3ob), 1, 3, 12, 24, 120 and 168 hours after the beginning of reperfusion/deobstruction. Duodenal (GII) and ileum (GIII) obstructions changed serum and peritoneal fluid biochemical analysis. However, only lactate, lactate dehydrogenase, creatine kinase and inorganic phosphorus concentrations were abnormal in peritoneal fluid three hours after the obstruction. The biochemical analysis of peritoneal fluid allowed a faster diagnostic of intestinal alterations than the serum analysis; hence it should be prioritized when pre-operatory colic assessment is carried out.

Palatoplastia com biomembrana natural de látex com polilisina 0,1% em cães com defeito palatino experimentalmente induzido

The palatoplasty is a correction surgery to restore the isolation between the oral and nasal cavity, avoid breath of food. There are many techniques to repair palatal defects, and the most used is mucoperiosteal flap. Grafts and prothesis, can be used too. Scientific works with Natural Latex Biomembrane with 0,1% Polylisine reveals properties like biocompatibility, improve and accelerate the cicatricial process, the stimulation of new vessels and organized tissue growth in different organs. Seven dogs were arranged in two groups and were submitted to experimental hard palate cleft. Five dogs received palatal repair with the natural latex biomembrane with 0,1% polylisine. Two animals did not receive any repair (control group) and the defect healing by second intention. After surgery, the groups were observed macroscopically and clinically to evaluate the results. The healling of cleft palate of group I was faster than control group, and this fact suggests that the biomembrane is an accelerator factor for cicatricial process.

Stable singularities of co-rank one quasi homogeneous map germs from (ℂn+1, 0) to (ℂn, 0), n = 2, 3

In this article, we investigate the geometry of quasi homogeneous corank one finitely determined map germs from (ℂn+1, 0) to (ℂn, 0) with n = 2, 3. We give a complete description, in terms of the weights and degrees, of the invariants that are associated to all stable singularities which appear in the discriminant of such map germs. The first class of invariants which we study are the isolated singularities, called 0-stable singularities because they are the 0-dimensional singularities. First, we give a formula to compute the number of An points which appear in any stable deformation of a quasi homogeneous co-rank one map germ from (ℂn+1, 0) to (ℂn, 0) with n = 2, 3. To get such a formula, we apply the Hilbert's syzygy theorem to determine the graded free resolution given by the syzygy modules of the associated iterated Jacobian ideal. Then we show how to obtain the other 0-stable singularities, these isolated singularities are formed by multiple points and here we use the relation among them and the Fitting ideals of the discriminant. For n = 2, there exists only the germ of double points set and for n = 3 there are the triple points, named points A1,1,1 and the normal crossing between a germ of a cuspidal edge and a germ of a plane, named A2,1. For n = 3, there appear also the one-dimensional singularities, which are of two types: germs of cuspidal edges or germs of double points curves. For these singularities, we show how to compute the polar multiplicities and also the local Euler obstruction at the origin in terms of the weights and degrees. © 2013 Pushpa Publishing House.

Stress analysis in oral obturator prostheses: Imaging photoelastic

Maxillary defects resulting from cancer, trauma, and congenital malformation affect the chewing efficiency and retention of dentures in these patients. The use of implant-retained palatal obturator dentures has improved the self-esteem and quality of life of several subjects. We evaluate the stress distribution of implant-retained palatal obturator dentures with different attachment systems by using the photoelastic analysis images. Two photoelastic models of the maxilla with oral-sinus-nasal communication were fabricated. One model received three implants on the left side of the alveolar ridge (incisive, canine, and first molar regions) and the other did not receive implants. Afterwards, a conventional palatal obturator denture (control) and two implant-retained palatal obturator dentures with different attachment systems (O-ring; bar-clip) were constructed. Models were placed in a circular polariscope and a 100-N axial load was applied in three different regions (incisive, canine, and first molar regions) by using a universal testing machine. The results were photographed and analyzed qualitatively using a software (Adobe Photoshop). The bar-clip system exhibited the highest stress concentration followed by the O-ring system and conventional denture (control). Images generated by the photoelastic method help in the oral rehabilitator planning. © 2013 SPIE.

Extraoral alar base cinch. A modification for the technique

The alar base widening is directly related to the Le Fort I osteotomy which could lead to an undesirable facial change if not adequately controlled transoperatively. Several surgical techniques to control the lateralization and widening of the nasal base have been described in the literature. The extraoral technique, first described by Shams and Motamedi in 2002 seems to make this procedure more predictable and reliable. The authors preset a modification for that technique. © 2013 Asian AOMS, ASOMP, JSOP, JSOMS, JSOM, and JAMI.
