Effect of oils sources on blood lipid parameters of commercial laying hens
Murata, LS;Ariki, J;Machado, CR;Silva, L da PG da;Rezende, MJM;
Revista Brasileira de Ciência Avícola , 2003, DOI: 10.1590/S1516-635X2003000300008
Abstract: the experiment was carried out to verify if total cholesterol, hdl-cholesterol and triacylglicerol plasma levels are affected when laying hens are fed rations containing different dietary oil sources. one hundred sixty 50 week-old hens, assigned to four treatments with five replicates using 8 hens per replicate were used. the experimental period was of 84 days divided in 3 cycles of 28 days each. in the last day of each cycle, blood samples of 2 hens per replicate were randomly choose and blood samples were collected. on the other hand, blood was also collected at 7 am, 11 am and 3 pm aiming to study the daily changes of these lipids. blood lipid parameters were not affected by different dietary oil sources (p > 0.05); however, hdl-cholesterol did change during the day, giving evidence that this lipid is indeed involved in the egg yolk formation.

Abstract: The experiment was carried out to verify if total cholesterol, HDL-cholesterol and triacylglicerol plasma levels are affected when laying hens are fed rations containing different dietary oil sources. One hundred sixty 50 week-old hens, assigned to four treatments with five replicates using 8 hens per replicate were used. The experimental period was of 84 days divided in 3 cycles of 28 days each. In the last day of each cycle, blood samples of 2 hens per replicate were randomly choose and blood samples were collected. On the other hand, blood was also collected at 7 am, 11 am and 3 pm aiming to study the daily changes of these lipids. Blood lipid parameters were not affected by different dietary oil sources (p > 0.05); however, HDL-cholesterol did change during the day, giving evidence that this lipid is indeed involved in the egg yolk formation.

Abstract: The solvent extraction process combined with tools of experimental design assists in developing procedures for separation and purification of elements or mineral compounds with high purity. In this work the technique was used to replace the traditional methods for the collection of basic information required for the development of a circuit of solvent extraction. According to the literature, several factors may influence the extraction of divalent metals by D2EHPA in sulfate media, among which the concentration of metals in solution. The objective was to study the variables affecting the separation process Mn/Ni/Co/Cu, such as the aqueous/organic (A/O), contact time, concentrations of the divalent metals in sulfuric medium, pH and solvent concentration. An investigation into the variables that control the process was done using a “cube + star” experimental design, with central point. The results demonstrate it is possible to obtain of a satisfactory mathematical model that describes the process.

Abstract: background: the physician's greatest effort at the inguinal hernia surgery is to prevent its recurrence. aim: to communicate the use of free flap of "fascia transversalis" added to a triangular inguinal reinforcement. methods: it was proceeded a surgery on a patient who carried a direct inguinal hernia, whose "fascia transversalis" was wide, thick and strechful. it was extracted one central round part of the fascia which was replaced as one free graft after the classical reinforcement of the triangular "fascia transversalis" inguinal. result: in follow-up of two years there is no recurrence. conclusion: a free graft from "fascia transversalis" when abundant may be used in surgery of inguinal hernia.
Técnica do aproveitamento da papila íleo-cecal naileostomia definitiva e na anastomose íleo-retal

ABCD. Arquivos Brasileiros de Cirurgia Digestiva (S?o Paulo) , 2011, DOI: 10.1590/S0102-67202011000100017
Abstract: introduction: when ileostomy is done with the ileum-caecal papilla, the liquid is decreased and happens much less local irritation and its possible that the patient can live without the use of the bag. objective: to show a surgical technique that preserves the papilla in ileostomy or ileo-rectal cancer. method: it is done with the preservation of the vasculature of the cecum and terminal ileum; cecum section is made leaving 1 cm border, coronal, on the ileal papilla, which is fixed on the skin for a counter-opening for permanent ileostomy. when a colectomy is needed, the anastomosis can be made with the rectal stump (papilla-ileum-retostomy). results: they are good because there is a decrease in the number of bowel movements, loss of fluid in the stool and less epidermal irritation. conclusion: the procedure is feasible and brings results that improve the quality of life of patients.
Repara??o da parede abdominal anterior com o omento maior

ABCD. Arquivos Brasileiros de Cirurgia Digestiva (S?o Paulo) , 2011, DOI: 10.1590/S0102-67202011000300014
Abstract: introduction: the loss of substance of the abdominal wall is usually replaced by synthetic prostheses with advantages and disadvantages. the greater omentum is a totipotent structure and can be applied also to this repair. objective: to present technical possibility of abdominal closure after resection of abdominal wall muscle part with omentum. method: the technic was carried out in two adult patients with colonic adenocarcinoma with invasion of the right abdominal wall. was required the resection of the right half of the abdominal wall to join the en-bloc resection. the left half of the greater omentum was used to seal the abdominal cavity fixing it with sutures to the edges of the surgical wound. final closure was done with the skin freed from the flanks. the recovery was satisfactory. in the late postoperative period incisional hernia occurred. conclusion: the greater omentum can be used to repair the partial loss of the abdominal wall.
Amputa??o abd?mino-perineal mais colostomia para-vaginal no tratamento do cancer reto-anal

Revista Brasileira de Coloproctologia , 2009, DOI: 10.1590/S0101-98802009000400011
Abstract: the author presents a proposal and lhe initial attempties to avoid the abdominal colostomy when it has to be definitive. in the woman was possible its execution, since it took advantage from the vulvovaginal esfincteral muscle nohen it can be preserved ot the anus-rectum amputation. the colon, prepared wit the valves, descend posteriorily from the vagina, inside the vulvo-vaginal esfincteral group. the initial observations shows that this attempt could be better developed for cotinency etudies.

Revista Brasileira de Engenharia Agrícola e Ambiental , 2003, DOI: 10.1590/S1415-43662003000200021
Abstract: in 1996 one water level recorder and three recording rain gauges were installed in the capetinga streamlet watershed at 'fazenda água limpa' at university of brasília, allowing to measure some hydro-meteorological parameters. knowing the monthly average of the stream flow and the specific average, it was possible to draw the respective permanence curves of the monthly average discharge of capetinga streamleat. from these curves it was possible to determine values of minimum monthly average at 95% probability level (q95) and of minimum specific monthly average at 95% probability level (q95). there was not discrepancy among the q95 and the ratio betwen q95 and the watershed area. the general extreme value type 1 or gumbel distribution was used to calculate the return period of the maximum instantaneus annual stream as well the least annual stream with seven days period. the return periods of 5, 10, 20, 50 and 100 years it was evaluated for maximum and minimum events. it was found that gumbel distribution adjusted very well to describe the maximum events observed as well as calculated ones, whereas for the minimum events there was no discrepancy.
Efeito do tratamento químico de sementes de arroz no controle da brusone nas folhas e na qualidade sanitária e fisiológica das sementes

Abstract: a field experiment was carried out in two successive years (2004 and 2005) in order to evaluate the effectiveness of the fungicides in rice seed treatment to control leaf blast. another experiment was carried out in the laboratory to analyze the physiological and sanitary profile of treated seeds. the statistical analysis showed significant differences for the area under the disease progress curve (audpc). the pyroquilon and azoxystrobin treatments showed the least severity of leaf blast with the lowest audpc. carboxim + thiram did not differ from the test to control leaf blast in the field, but this treatment increased seed germination (22%) compared with the other treatments and with the untreated control. in general, all treatments were efficient in reducing and/or eliminating fungi in seeds, with best results from carboxin + thiram and tricyclazole.
