Contribution in the diagnosis of ultrasonography perinephric pseudocyst uriniferous in a feline - case report

The renal pseudocysts are accumulations of fluid unilateral or bilateral perirenal location, contained in a capsule without epithelium, a characteristic that distinguishes them from true renal cysts. The capsule itself may have originated in the renal capsule or a localized inflammatory reaction. The nature of the fluid can vary, but the presence of ooze found the most common, but they are also called pseudocysts accumulations of urine, blood and lymph. The most frequently observed clinical sign is abdominal distention. However these nonspecific signs may be related to chronic kidney disease and azotemia that may develop before or after the formation of this lesion. The abdominal ultrasound is less invasive and allows you to diagnose this change more easily, also allowing the collection of fluid guided percutaneous and submit it to cytological, biochemical and bacteriological in order to obtain information about its nature. This paper aims to describe a case of perinephric pseudocyst in a cat uriniferous, highlighting the contribution ultrasound as a diagnostic method complementary quick and noninvasive, allowing evaluation of the architecture of the renal parenchyma, differentiation of cortex and spinal cord as well as detect changes in size and shape of it, aiming for better planning in clinical surgery.

Histopathological and b-mode ultrasound characteristics in a primary canine duodenal adenocarcinoma - case report

Lower gastrointestinal tract neoplasms are rare in domestic animals, representing 3% of all biopsies and necropsies. Our objective is to describe the histopathological and B-mode ultrasound findings in a case of duodenal adenocarcinoma in a dog, since it commonly occurs in the large intestine. On ultrasound examination, there was transmural wall thickening in the duodenum with loss of layer structure, focal peritonitis and adenopathy. Histopathological examination of the intestinal mass revealed a malignant epithelial neoplasm, densely cellular and infiltrative, extending through the lamina propria, submucosa, muscle and hypodermis, characterizing a duodenal adenocarcinoma. We conclude that adenocarcinomas may be included in the differential diagnosis of transmural lesions in the duodenum in B-mode ultrasound examinations, but a laparotomy and biopsy are required for definitive diagnosis.

Youth purpose and life goals of students engaged in community and social activities

Purpose provides a moral compass for young people to apply their strengths and virtues in their lives. Deepen the studies about youth purpose may contribute to the design of new and more efficient moral education strategies, aiming the development of greater citizenship awareness, social justice and youth engagement in the construction of a society based on democracy, justice and social solidarity. This research paper explores the identification of life goals, the beyond the self or self-oriented purpose in life, a meaningful engagement in purposeful activities and the well-being and satisfaction with life in Brazilian youth engaged and not engaged in social and community issues.

Very Intense Distinct Blue and Red Photoluminescence Emission in MgTiO 3 Thin Films Prepared by the Polymeric Precursor Method: An Experimental and Theoretical Approach

MgTiO3 (MTO) thin films were prepared by the polymeric precursor method with posterior spin-coating deposition. The films were deposited on Pt(111)/Ti/SiO2/Si(100) substrates and heat treated at 350 °C for 2 h and then heat treated at 400, 450, 500, 550, 600, 650 and 700 °C for 2 h. The degree of structural order−disorder, optical properties, and morphology of the MTO thin films were investigated by X-ray diffraction (XRD), micro-Raman spectroscopy (MR), ultraviolet− visible (UV−vis) absorption spectroscopy, photoluminescence (PL) measurements, and field-emission gun scanning electron microscopy (FEG-SEM) to investigate the morphology. XRD revealed that an increase in the annealing temperature resulted in a structural organization of MTO thin films. First-principles quantum mechanical calculations based on density functional theory (B3LYP level) were employed to study the electronic structure of ordered and disordered asymmetric models. The electronic properties were analyzed, and the relevance of the present theoretical and experimental results was discussed in the light of PL behavior. The presence of localized electronic levels and a charge gradient in the band gap due to a break in the symmetry are responsible for the PL in disordered MTO lattice.

Freezing Distortions and Photoluminescence Property in PbMoO4 Micro Octahedrons: An Experimental and Theoretical Study

In this paper, we report a detailed structural and electronic characterization of PbMoO4 crystals by using a conventional hydrothermal (CH) method. The samples were characterized by X-ray diffraction (XRD), Fourier transform Raman (FT-Raman), field-emission gun scanning electron microscopy (FEG-SEM) and photoluminescence (PL) measurements. In addition, first-principles quantum mechanical calculations based on the density functional theory were employed in order to understand the band structure and density of states for the PbMoO4. Analysis of both theoretical and experimental results allows to rationalize the role of order-disorder effects in the observed green PL emissions in these ordered powders.

A angústia e a ficção contemporânea

Our aim in this article is to accomplish an afterthought concerning contemporary fiction. Taken as initial the afterthought of the role of the novel as fiction and its linking with the afterthought of mimesis in modernity, we aim to consider the presence of agony not only as a theme but also as a structural element of narratives. Eventually, we will make brief tallies of theses aspects in the work of José Saramago.

A presença da angústia em um conto de Mia Couto

This article intends an approach among literary analysis, philosophy and psichoanalysis in a short story from Mia Couto, Mozambican author. From the trajectory of the main character and from their relationship with the others, we intended to do a reading on the presence of anguish within this literary text. In order to do that, two definitions were used to explain what would be considered torment: one from the philosopher Kierkegaard and the other from the psichoanalyst Freud. Concluding, we aim to compare this two readings in a way that we establish bounds between both.

Um passeio com mito e história nA cidade de Ulisses, de Teolinda Gersão

La novela A cidade de Ulisses (2011), de la escritora portuguesa contemporánea Teolinda Gersão, nos presenta una Lisboa envuelta en mitos e historia. Este trabajo pretende inferir las relaciones entre estos dos campos del conocimiento y sus implicaciones para la construcción de los sentidos del texto. Teniendo en cuenta la leyenda que cuenta que la capital portuguesa fue fundada por Ulisses, el héroe homérico, la narrativa se vale de elementos míticos para, junto con el relato del personaje Paulo Vaz acerca de sus relaciones románticas con Cecília Branco y Sara, hacer referencia a cuestiones del pasado y del presente histórico portugueses, siempre de manera crítica. Buscamos, así, indagar, a través del mito, cómo se introduce la historia en el universo del texto.

Uma representação irônica da morte e da escrita

The novel As intermitências da morte, by José Saramago (2005a), presents an imaginary narrative that treats one of the most classical themes of universal literature. Besides that, the novel discusses the question of fictional discourse construction, showing the potentialities (and limits) of language as an intermediation between life and art.

Sealing composite with defective margins, good care or over treatment? results of a 10-year clinical trial

Purpose: The objective of this study was to clinically evaluate sealed composite restorations after 10 years and compare their behavior with respect to controls. Methods and Materials: The cohort consisted of 20 patients aged 18 to 80 years with 80 composite restorations. All participants in the sealing and no-treatment groups presented with clinical features for the marginal adaptation that deviated from the ideal and were rated Bravo (United States Public Health Service criteria). Composites with Alfa values for the marginal adaptation were used as the positive control. Results: The marginal adaptation behavior was similar between the sealing and control (+) groups, with a high frequency of Bravo values in the 10th year (80% and 51%, respectively). Most of the no-treatment (-) group maintained the Bravo values (91%) for 10 years, although some restorations (9%) progressed to Charlie values. The anatomy parameter differed significantly between the first and 10th years, with deterioration in all three groups (p,0.05). The secondary caries parameter had a similar behavior in the three groups (p.0.05). Conclusions: Sealing the margins of the composite resin restorations had no significant effect compared with the control groups, under the conditions of this study. Sealing the restorations substantially improved the marginal staining and marginal adaptation parameters, although by the tenth year they were similar to the group without intervention.

Por que ainda é importante pensar como um nômade em nosso tempo

This article argues for the existence of a nomadic way of thinking, in accord with Deleuze and Guattari’s proposals throughout their “nomadology”. I will look forward to develop such an argument through of four points: the epistemological, the political, the historical and the ontological one. These four points, in set, describe what we call nomadic thought. Such reflection is defined in the observation of a dominant process that constitutes subjectivities ruled by a “capitalist axiomatic”, in our time. Such process is understood as a nomadic device involving, as its main by-product, what is called of narcissism of the difference. However, if the dominant way of becoming subjects ruled by capitalist society, in our time, is nomadic, is it still worthwhile thinking as a nomad, as pursued Deleuze and Guattari?

Ultrasound-assisted periconal ocular blockade in rabbits

ObjectiveThis study aimed to evaluate the benefit and specifically the feasibility of using ultrasound in ophthalmologic periconal block, and the occurrence of complications.Study designProspective experimental study.AnimalsTen healthy New Zealand White rabbits (6-8months of age), weighing 2.0-3.5kg.MethodsRabbits were anesthetized by intramuscular injection of acepromazine (1mgkg(-1)), ketamine (30mgkg(-1)) and xylazine (3mgkg(-1)). Ultrasound-assisted periconal block with lidocaine was performed on 18 eyes. Intraocular pressure was measured by applanation tonometry whereas corneal sensitivity was assessed using an esthesiometer, before and after each periconal anesthesia.ResultsIn all 18 eyes, it was possible to adequately visualize the needle shaft within the periconal space, as well as muscular cone, optic nerve and local anesthetic solution spread. Lidocaine 2% without epinephrine (0.790.19mL) was injected into the periconal space. There was no statistical difference between the intraocular pressure (meanSD) measured before (10.9 +/- 2.9mmHg) and after (11.9 +/- 3.8mmHg) the periconal anesthesia (p=0.38). The effectiveness of the ultrasound-assisted technique was shown according to the values for corneal sensitivity, assessed before and after periconal anesthesia (p<0.0001). Complications were not observed in this study.ConclusionsEye ultrasonography allowed visualization of all anatomic structures necessary to perform a periconal block, as well as the needle insertion and anesthetic spread in real time. Further studies are required to prove the real potential of ultrasound for reducing the incidence of complications associated with ophthalmic blocks, especially when anatomic disorders of the eye could potentially increase the risk.Clinical relevanceUltrasonography is a painless, noninvasive tool that may improve safety of ophthalmic regional blocks, potentially by reducing the prevalence of globe perforation or penetration of the optic nerve associated with the needle-based techniques.
