Abstract: objective: to evaluate the effectiveness of banded roux-en-y gastric bypass in promoting weight loss after an eight-year follow-up. methods: two hundred and eleven obese patients underwent roux-en-y gastric bypass with banding by the same surgical team. the study design was longitudinal, prospective and descriptive. the analysis of weight decrease in the postoperative period was based on the loss of excess weight in percentage and bmi. failure was considered when patients lost <50% of excess weight. results: the loss of follow-up was 36.5%, therefore, 134 patients were included in this study. the loss of excess weight in global average rate in the postoperative period was: 67.6 ± 14.9% in the first year, 72.6 ± 14.9% in the second year, 69.7 ± 15.1% in fifth year and 66.8 ± 7.6 in eight years. surgical treatment failure occurred in 15 patients (7.1%) over the period. conclusion: banded roux-en-y gastric bypass was effective in promoting and sustaining weight loss in the long term, with low failure rates.

Abstract: background: various techniques have been used for the surgical treatment of esophageal achalasia, however, the best results for non - advanced esophageal achalasia has been achieved by miotomy. laparoscopy for non advanced esophageal achalasia have been showing similar results than convencional surgery, with the benefits of a minimally invasive procedure. the aim of this study was to analyze the results of laparoscopy heller miotomy and dor fundoplication for non - advanced esophageal achalasia. methods: twelve patients with non - advanced esophageal achalasia submitted to laparoscopic heller miotomy and dor fundoplication from jan/99 to dec/01 were prospectively analised. results: all surgeries were completed by laparoscopy with no conversion. nine patients were assymptomatic and tree presented dysphagia, regurgitation and heartburn, respectively. these patients had a median follow-up of 13.2 months (9-39). there were two cases of gastric perfuration and one case of esophageal perfuration but no deaths occured in this series. conclusion: based in this study, we could conclude that the heller miotomy associated to the dor fundoplication by laparoscopy has a low complication rate. its use was effective and safe for esophageal achalasia. the surgery is perfectively performed by laparoscopy, with results similar to those of laparotomy, added to the benefits of minimally invasive surgery.

Abstract: background: the aim of the study is to state if the ring used in the roux-en-y gastric bypass is related to the weight loss after surgery. methods: the study has a 5 years follow up. after endoscopic examination the patientes were divided in two groups: internal diameter of the ring till 10mm (184 patients) and other group with internal diameter of the ring more than 10 mm (107 patients).the excess of weight loss were measured one, two and five years after surgery and compared one with each other. results: the excess of weight loss was higher for those patients with tighter ring. statistc analysis was significant comparing the two groups one, two and five years after surgery, the excess of weight loss was higher in the tighter ring groups for each time after surgery. there were no difference related to sex, age and bmi. conclusion: the restriction determined by ring increases the excess of weight loss in patients submitted to roux-en-y gastric bypass.

Abstract: background: this study wants to establish if there is an association between gallbladder hypomotility in obese patients before bariatric surgery and gallstone development after weight loss. methods: from september 2002 to january 2005 using realtime ultrasonography we evaluated fasting and postprandial (60th minute) gallbladder volumes and ejection fractions in ninety six morbid obese patients prior to bariatric surgery. these patients were followed one year after bariatric surgery with gallbladder ultrasonography to identify cholelithiasis. results: there were twenty seven (28.12%) with gallbladder hypomotility, seven (29.62%) of them had cholelithiasis in the postoperative period. eighteen of ninety six patients (18.75%) had developed gallstones. conclusion: there were no statistical differences between cholelithiasis development both in patients with hypomotility and with normal gallbladder motility.
Há 100 anos, a descoberta do Treponema pallidum

Abstract: the discovery of treponema pallidum by schaudinn & hoffmann, on march 3rd 1905, was influenced by siegels' communication on the finding of the etiological agent of syphilis. john siegel, working at the institut of zoology, university of berlin, claimed to have found a flagellate protozoon in syphilitic lesions. because of the skepticism it was received with, this communcation yielded further investigation, conducted by zoologist schaudinn and dermatologist hoffmann. they were the first investigators to find the etiological agent of syphilis, described under the name of spirochaeta pallida. the discovery of treponema pallidum on march 3rd 1905 was the first step towards the development of diagnostic and therapeutic procedures in subsequent years.

Abstract: Glyphosate is the most widely used herbicide in the world. In sugarcane, it is used as a herbicide when applied at its field rate, but it is also used as ripener when applied as low doses. However, the effects of glyphosate on plant metabolism and sugarcane growth are not fully understood. This study aimed to evaluate the metabolic changes and the effects on sugarcane plant growth caused by the application of different doses of glyphosate. Sugarcane plants were grown in a greenhouse and subjected to glyphosate applications at doses of 7.2; 18; 36; 72; 180; 360 and 720 g a.e. ha-1. Plants grown without an herbicide application were used as a control. Plants from each treatment were collected at 2, 7, 14, and 21 days after treatment (DAT) application to quantify the levels of shikimic acid, quinic acid, shikimate-3-phosphate, glyphosate, α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA), phenylalanine, tyrosine, and tryptophan. Visual evaluations of plant intoxication were performed at the same time as the collection of plants, and the quantification of their shoot dry biomass was performed at 21 DAT. At doses of glyphosate greater than 72 g a.e. ha-1, increases in the levels of shikimic acid, quinic acid, and shikimate-3-phosphate occurred and AMPA was detected in the plants. Initially, glyphosate caused increases in the plant levels of phenylalanine and tyrosine at doses of 72 and 180 g a.e. ha-1, although a decrease in the levels of aromatic amino acids subsequently occurred at and above the doses of 72 or 180 g a.e. ha-1. The doses ranging from 7.2 to 36 g a.e. ha-1 promoted an increase in plant shoot biomass, and doses greater than 72 g a.e. ha-1 caused significant reductions in dry mass.

Abstract: the objective of this research was to evaluate the effects of barley and weed control periods on the seed production and growth of raphanus sativus, the major weed in the experimental area. the experiment was carried out in botucatu, sp, brazil. two checks, with and without the crop, were kept weedy from seeding to harvest. in other eight treatments the crop was kept weed free up to 10, 20, 30, 40, 50, 60, 80 and 100 days after emergence. it were evaluated the number of plants, the dry matter accumulation and the number of fruits and seeds per plant and per m2, the weight of 1.000 seeds and the percent of the seeds in the total dry matter accumulation. raphanus sativus showed a high reproductive potential, producing 5. 074 seed s/m2 if kept without control in the absence of the crop. barley reduced the growth and the seed production of r. sativus. to reduce de seed production to values lower than the population density of the r. sativus in the checks, the weed should be controlled up to 30-100 days after crop emergence.

Abstract: the interactions of glyphosate and one adhesive spreading (concentrate of alcoholphenols with ethene-oxide and organic sulfonates) in reducing the surface tension and controlling brachiaria decumbens and panicum maximum were evaluated. it were used comercial products with 360 g a.e/l and 466 g i.a./l, respectivelly. to achieve similar control levels, the herbicide rates should be 24,05% higher for the second species. the herbicide reduced the effect of the surfactant on surface tension. the concentration of 0,1 % (c.p.) of the surfactant maximized the efficacy of glyphosate in controlling the two grasses.
