Case Reports in Surgery , 2012, DOI: 10.1155/2012/964093
Abstract: Introduction. Visceral artery aneurysms are uncommon. Among them, splenic artery is the most common (46–60%). Most splenic artery aneurysms are asymptomatic and diagnosed incidentally, but its rupture, potentially fatal, occurs in up to 8% of cases. Presentation of Case. A female patient, 64 years old, diagnosed with a giant aneurysm of the splenic artery (approximately 6.5?cm in diameter) was successfully submitted to endovascular treatment by stent graft implantation. Discussion. Symptomatic aneurysms and those larger than 2?cm represent some of the main indications for intervention. The treatment may be by laparotomy, laparoscopy, or endovascular techniques. Among the various endovascular methods discussed in this paper, there is stent graft implantation, a method still few reported in the literature. Conclusion. Although some authors still consider the endovascular approach as an exception to the treatment of SAA, in major specialized centers these techniques have been consolidated as the preferred choice, reserving the surgical approach in cases where this cannot be used. For being a less aggressive approach, it offers an opportunity of treatment to patients considered “high risk” for surgical treatment by laparotomy/laparoscopy. 1. Introduction Visceral artery aneurysms (VAAs) are uncommon. Among them, splenic artery is the most common (46–60%), followed by hepatic artery (20%) and superior mesenteric artery (5-6%) [1–6]. Seventy-five percent of VAAs are asymptomatic. The most common symptom is pain in the upper left quadrant of the abdomen or in the epigastrium, radiating to left shoulder, nausea, and vomiting. [1, 2, 7, 8]. The rupture occurs in 3% to 8% of cases, is manifested by hypovolemic shock, and is potentially fatal [1, 2, 4, 7, 8]. The splenic artery aneurysms can be approached by laparotomy, laparoscopy, or endovascular techniques. The endovascular option, less invasive, has less morbidity and faster postoperative recovery [1–4, 8]. Among the various endovascular techniques, covered stent implantation has been little reported in the literature. The authors present a case of splenic artery aneurysm treated by this method. 2. Presentation of Case A female patient, 64 years old, controlled hypertension, and 2 previous pregnancies, presented as main complaint episodes of mild pain in the epigastrium and left hypochondrium, evolving for about 12 months. Physical examination of the abdomen was nonspecific, with ill-defined pain on palpation of the mesogastrium and left hypochondrium. In the hospital of origin she was submitted to

Abstract: we report a case of a patient with a major complaint of left lumbar pain, diagnosed with bilateral renal angiomyolipomas (amlrs), with the most voluminous lesion of 6.2 cm in its largest diameter, underwent endovascular superselective arterial embolization with microspheres. the amlrs are rare benign tumors. most are sporadic, while a minority is associated with tuberous sclerosis complex (etc). the amlrs larger than 4 cm must be treated due to higher risk of complications, especially hemorrhagic. a selective arterial embolization (eas) is an effective and safe treatment for amlrs.

Abstract:

This study was conducted to evaluate the physiological quality of forage seeds after passage through the gastrointestinal tract of cattle, as well as the emergence of seedlings derived from these seeds. Three Fabaceae species were used: tropical kudzu, leucaena and calopo. One hundred grams of seeds of each species were offered, separately, to five bovines. After the start of the dispersion, the faeces of the animals were collected every 6 hours, in a total of 72 hours, being taken to the greenhouse immediately after each collection. The study evaluated the total number of seedlings in the stool, the lengths of roots and aerial parts, as well as the natural and dry seedling weight thirty days after the disposal of the faeces in the greenhouse. The experimental design consisted of randomized blocks, with twelve treatments (sampling periods) and five replications (cattle). The best performance for the total number of seedlings in the faeces of cattle was observed in the kudzu species. The length of the root, length of the aerial part and dry matter seedling weight was observed in the leucaena species, followed by kudzu. The calopo showed low results for all variables due to the high degradation of the seeds.

Abstract: Background: Dengue is a Neglected tropical disease (NTDs) with high incidence in Brazil. This disease is caused by Dengue virus and is transmitted by Aedes aegypti mosquito. The search for new approaches for controlling of this disease is the subject of numerous studies. The aaNAT is a key enzyme in the metabolism of A. aegypti and is crucial in the sclerotization process, as well as regulation of circadian rhythm and inactivation of neurotransmitters. Computational techniques applied to studies of biological systems become an effective weapon in the mapping and management of 3D data structures, giving direction and guidance of potential ligands that can form stable complexes with targets of interest, using a Molecular Docking approach. The present study was conducted by a virtual screening, followed by docking calculations, in order to find molecules that could inhibit aaNAT. In this study, we used available compounds in SAM database (Bioinformatics and Medicinal Chemistry Laboratory—Southwest Bahia State University, Jequié-Bahia, Brazil), PubChem and ZINC. Results: The result of dockings with selected ligands showed good energy affinities, presenting potential inhibitory interactions with the enzyme active site. Conclusions: The Coa-S-acetyl-tryptamine and 3-indoleacriloil-coenzyme-A showed the same binding energies -8.9 Kcal/Mol and were described as possible inhibitors of aaNAT.

Abstract: Positive Montenegro's skin test is a delayed type hypersensitivity reaction widely used as indicative of previous infection with Leishmania in both humans and dogs. Montenegro's antigen consists of a crude Leishmania antigen solution, usually containing thimerosal as preserving agent. In this work it is shown that a large proportion of dogs (11 out of 56) examined in an endemic area of leishmaniasis presented induration at the site of injection of a diluent containing thimerosal alone. This clearly demonstrates that thimerosal leads to a high number of false positive skin reactions in dogs and that its use in Montenegro's skin test antigenic preparations should be avoided.

Abstract: simple manual reaction time (mrt) to a visual target (s2) is shortened when a non-informative cue (s1) is flashed at the s2 location shortly before the onset of s2 (early facilitation). afterwards, mrt to s2 appearing at the s1 location is lengthened (inhibition of return - ior). similar results have been obtained for saccadic reaction time (srt). moreover, when there is a temporal gap between offset of the fixation point (fp) and onset of a target (gap paradigm), srt is shorter than srt in an overlap paradigm (fp remains on). in the present study, we determined srt to s2 (10o) after presenting s1 at the same eccentricity (10o) or at a parafoveal position (2o) in the same or in the opposite hemifield. in addition, we employed both gap and overlap paradigms. twelve subjects were asked not to respond to s1 (2o or 10o) to the right or to the left of fp, but to respond by making a saccadic movement in response to s2. we obtained the following results: 1) a 40-ms gap effect, 2) an interaction between gap effect and ior, 3) a 39-ms delay (ior) when s2 appeared at the cued (s1) position, and 4) a smaller (17 ms) but significant inhibition when s1 occurred at 2o in the ipsilateral hemifield. thus, a parafoveal (2o) s1 elicits an inhibition of srt towards ipsilateral peripheral targets. since an inhibition of the ipsilateral hemifield by a 1o eccentric cue has been reported to occur when manual responses are employed, we suggest that the postulated functional link between covert and overt orienting of attention is also valid for parafoveal cues.

Abstract: Simple manual reaction time (MRT) to a visual target (S2) is shortened when a non-informative cue (S1) is flashed at the S2 location shortly before the onset of S2 (early facilitation). Afterwards, MRT to S2 appearing at the S1 location is lengthened (inhibition of return - IOR). Similar results have been obtained for saccadic reaction time (SRT). Moreover, when there is a temporal gap between offset of the fixation point (FP) and onset of a target (gap paradigm), SRT is shorter than SRT in an overlap paradigm (FP remains on). In the present study, we determined SRT to S2 (10o) after presenting S1 at the same eccentricity (10o) or at a parafoveal position (2o) in the same or in the opposite hemifield. In addition, we employed both gap and overlap paradigms. Twelve subjects were asked not to respond to S1 (2o or 10o) to the right or to the left of FP, but to respond by making a saccadic movement in response to S2. We obtained the following results: 1) a 40-ms gap effect, 2) an interaction between gap effect and IOR, 3) a 39-ms delay (IOR) when S2 appeared at the cued (S1) position, and 4) a smaller (17 ms) but significant inhibition when S1 occurred at 2o in the ipsilateral hemifield. Thus, a parafoveal (2o) S1 elicits an inhibition of SRT towards ipsilateral peripheral targets. Since an inhibition of the ipsilateral hemifield by a 1o eccentric cue has been reported to occur when manual responses are employed, we suggest that the postulated functional link between covert and overt orienting of attention is also valid for parafoveal cues.

Abstract: this study aimed at estimating the kinetic parameters of ruminal degradation of neutral detergent fiber from agroindustrial byproducts of cashew (pulp and cashew nut), passion fruit, melon, pineapple, west indian cherry, grape, annatto and coconut through the gravimetric technique of nylon bag, and to evaluate the prediction equation of indigestible fraction of neutral detergent fiber suggested by the cornell net carbohydrate and protein system. samples of feed crushed to 2 mm were placed in 7 × 14 cm nylon bags with porosity of 50 μm in a ratio of 20 g dm/cm2 and incubated in duplicate in the rumen of a heifer at 0, 3, 6, 9, 12, 16, 24, 36, 48, 72, 96 and 144 hours. the incubation residues were analyzed for ndf content and evaluated by a non-linear logistic model. the evaluation process of predicting the indigestible fraction of ndf was carried out through adjustment of linear regression models between predicted and observed values. there was a wide variation in the degradation parameters of ndf among byproducts. the degradation rate of ndf ranged from 0.0267 h-1 to 0.0971 h-1 for grape and west indian cherry, respectively. the potentially digestible fraction of ndf ranged from 4.17 to 90.67%, respectively, for melon and coconut byproducts. the cncps equation was sensitive to predict the indigestible fraction of neutral detergent fiber of the byproducts. however, due to the high value of the mean squared error of prediction, such estimates are very variable; hence the most suitable would be estimation by biological methods.
