Abstract: the first description of severe pain in the distribution of the glossopharyngeal nerve is credited to weisenberg, in 19101, in a patient with cerebellopontine angle tumor. however, it was harris, in 19262, who coined the term glossopharyngeal neuralgia to describe this rare condition characterized by paroxysms of excruciating pain located laterally at the back of the tongue, soft palate, throat, and lateral and posterior pharynx, radiating to the ear. swallowing, coughing, yawning or chewing may trigger pain, which usually lasts from seconds to minutes. the association between glossopharyngeal neuralgia and syncope is very rare, being identified by brief episodes of bradycardia, asystole, and hypotension. such an association, with this same pathophysiology, was first described by riley et al3 in 1942.

Abstract: the material studied consists of a series of alloys with a basic composition (weight %): 18cr - 0.01 c - 0.2 si - 0.4 mn, and levels of nickel varying from zero to 60%. alloys in the annealed condition and after deformation at room temperature, 350 and 700°c to simulate the high temperatures achieved during machining were observed by optical microscopy. equilibrium diagrams were generated by computational thermodynamics (thermocalc) to predict the behavior of these alloys in a wide range of temperatures. the theoretical thermodynamic equilibrium conditions of the system were compared to the observed microstructures, indicating that the cfc phase in alloys with nickel content between 10% and 30% is, in fact, in a metastable condition at room temperature. martensitic transformation induced by cold work in the alloy with 10% ni was observed, validating the computer calculations.

Abstract: tensile tests were carried out at room temperature in fe-18% cr alloys, with nickel content varying between zero and 60%, and the properties obtained were correlated with the results of machinability previously obtained by the group. the alloys were also tested at 350 and 700°c in order to obtain these properties in the range of temperature compatible with the machining process. the ferritic alloy presented lower elongation and uts (ultimate tensile strength) than austenitic alloys at room temperature and 350°c, which explains why, in the machining process, the ferritic alloy shows much greater tool life if compared to austenitic alloys (100 against 20 to 50 minutes, respectively). in the test at 350°c, the temperature reached during machining, the increase in nickel content increased the uts of austenitic alloys, hampering the machining, and also elevated the ductility (elongation) that produces a higher volume of material adhered on the tool. this higher adhesion capacity, allied to a higher mechanical strength, explains the increase of tool wear as a function of increasing nickel content in the alloy with a consequent reduction in the life of the tool.

Abstract: The experiment was carried out in west of Paraná state, in Red Eutroferric Latosoil. The objective was to verify, in the establishment, the available P concentration in soil and critical doses of P to yield of dry matter (DM) and tillering and, in the 2° year, the growth of Panicum maximum cvs. Momba a and Tanzania-1 and Brachiaria sp. hibrid Mulato. The treatments were three forages and five P2O5 rates (0, 40, 80, 120 e 240 kg/ha) randomized in three complete blocks in factorial arrange. The phosphorus rates linearly increased the P available in soil extracted by Mehlich-1 method ( =-4,5136 + 1,0241X, R2=0,96, , in mg/dm3). The P application increased, up to maximum, the DM yield of forages Momba a ( =6.472 + 74,41X – 0,241X2 R2=0,97), Tanzania-1 ( =6.923 + 70,95X – 0,249X2, R2=0,88) and Mulato ( =7.393 + 94,42X – 0,341X2, R2=0,72) and the tiller density (TD). The critical phosphorus rates of 54, 44 e 48kg/ha of P2O5, respectively, to Momba a, Tanzania-1 and Mulato and P critical concentrations in soil of 51, 41 and 44mg/dm3. In the establishment, the mulato-grass presented highers DM yield and TD (11.169kg/ha and 69 tillers/0,25m2). The DM yield and TD in the momba a-grass (9.787kg/ha and 54 perfilhos/0,25m2) and the tanzania-grass (9.563kg/ha and 52 perfilhos/0,25m2) were equal. In the 2° year, there were no variations in DM yield. The highest leaf elogantion ratio (LER) and leaf appearance ratio (LAR) were obtained in momba a-grass and mulato-grass, respectively. The mulato-grass presented lower phylocron. O experimento foi conduzido na regi o Oeste do Paraná, em Latossolo Vermelho Eutroférrico de textura argilosa. O objetivo foi determinar, no estabelecimento, os teores críticos de P disponível e as doses críticas para produ o de matéria seca (PMS) e perfilhamento e, no 2° ano, o crescimento de Panicum maximum cvs. Momba a e Tanzania-1 e Brachiaria sp. híbrida Mulato. Os tratamentos foram: três forrageiras e cinco doses de P2O5 (0, 40, 80, 120 e 240kg/ha) em arranjo fatorial e em três blocos completos. As doses de P (kg/ha de P2O5) elevaram os teores de P-Mehlich-1 diponível ( =-4,5136 + 1,0241X, R2=0,96, , em mg/dm3). A aplica o de P aumentou, até determinado ponto, a PMS (kg/ha) dos capins Momba a ( =6.472 + 74,41X – 0,241X2 R2=0,97), Tanzania-1 ( =6.923 + 70,95X – 0,249X2, R2=0,88) e Mulato ( =7.393 + 94,42X – 0,341X2, R2=0,72) e a densidade de perfilhos (DP). As doses críticas foram 54, 44 e 48 kg/ha de P2O5 e os teores críticos de 51, 41 e 44mg/dm3, respectivamente, para Momba a, Tanzania-1 e Mulato. No estabelecimento, o capim-Mulat

Abstract: the most critical step in any proteomic study is protein extraction and sample preparation. better solubilization increases the separation and resolution of gels, allowing identification of a higher number of proteins and more accurate quantitation of differences in gene expression. despite the existence of published results for the optimization of proteomic analyses of soybean seeds, no comparable data are available for proteomic studies of soybean leaf tissue. in this work we have tested the effects of modification of a tca-acetone method on the resolution of 2-de gels of leaves and roots of soybean. better focusing was obtained when both mercaptoethanol and dithiothreitol were used in the extraction buffer simultaneously. increasing the number of washes of tca precipitated protein with acetone, using a final wash with 80% ethanol and using sonication to ressuspend the pellet increased the number of detected proteins as well the resolution of the 2-de gels. using this approach we have constructed a soybean protein map. the major group of identified proteins corresponded to genes of unknown function. the second and third most abundant groups of proteins were composed of photosynthesis and metabolism related genes. the resulting protocol improved protein solubility and gel resolution allowing the identification of 122 soybean leaf proteins, 72 of which were not detected in other published soybean leaf 2-de gel datasets, including a transcription factor and several signaling proteins.

Abstract: four weeks after containment vaccination undertaken against the largest outbreak of smallpox occured in brazil in 1969, that of the municipality of utinga, bahia, 99 samples of serum were collected from the local population. these samples were classified in four groups: a) - individuals with a history of variola prior to the beginning of present outbreak in town (15 sera); "previous smallpox group"; b) - individuals with primary vaccination, with no record variola, at the time of containment measures (15 sera). "primary vaccinated group"; c) - individuals with no previous record of variola revaccinated with "take" at the time of containment (15 sera0, "revaccinated group"; d) - individuals who contracted variola in present outbreak (54 sera) these were subdivided in four sub-groups, according to dates on which cases ocurred, "variola in outbreak group". serological study of samples was done by tests of hemagglutination inhibition, neutralization, and complement fixation. it was observed that hi titers were significantly lower in cases of previous smallpox than in other groups. although they were slightly higher on revaccinated individuals than on primary vaccinated group and than in the group of variola in outbreak, this difference was not significant. those same antibodies were present in all cases of variola in outbreak, and it was found that titers decreased in direct proportion to time elapsed from occurrence of cases. neutralizing antibodies proved to be significantly higher on the revaccinated group than on variola in outbreak group, and higher on these than on primary vaccinated and on the previous smallpox groups. in cases from the variola in outbreak it was verified that neutralizing antibodies remained stable, although with great variation in titers. tests of complement fixation could not be undertaken on all samples, because many of them proved to have anticomplementarity. however, it was found that complement fixing antibodies diminished rapidly, becomin

Abstract: objective: to study clinical and radiological data and surgical treatment for symptomatic ureteral duplications in childhood, especially the results for superior polar heminephrectomies. methods: prospective observational study concerning 15 pediatric patients surgically treated following a protocol with a minimum follow-up of 6 months. results: 93% of the patients presented urinary infection and/or fetal hydronephrosis during their first year of life. these were the usual reasons for evaluation. superior polar heminephrectomy was indicated for 80% of the patients, all of whom presented clinical and radiological improvement after the surgery. there were no significant complications. all children with severe vesicoureteral reflux to the duplicated superior pole presented symptomatic reflux to the stump after the surgery and were submitted to stumpectomy. none of the patients without preoperative reflux needed any other surgical procedure. conclusions: superior polar heminephrectomy is safe and efficient in order to treat ureteral duplications in childhood. if the patient does not present vesicoureteral reflux this will probably be the only surgery needed. most patients with reflux to the resected superior pole will need stumpectomy subsequently.

Abstract: the aids epidemic is spreading rapidly among women worldwide, offering increasing opportunities for vertical transmission of hiv. in brazil, the prevalence of hiv infection among pregnant women is less than 1%. therefore, the positive predictive value of an hiv eia test tends to be lower than the more frequent indeterminate western blot result. pregnant women receiving antenatal care, from 2000 to 2004, at a public secondary hospital in the city of presidente prudente, s?o paulo, brazil, were systematically screened for hiv by means of two distinct eia tests, in order to determine the prevalence of indeterminate western blot results among pregnant women showing discordance in both hiv eia tests and indirect immunofluorescence assay. confirmatory indirect immunofluorescence was performed on material for all women with positive results in both eia tests. whenever there were positive results in eia and iia, the applicant was retested by the initial screening assay. only those not showing concordance in results in eia and iaa had a western blot performed. the viral load was measured in pregnant women with positive or indeterminate western blot results. out of 9,786 sera, 105 (1.0%) were positive in the two hiv eia screening tests, confirmed by indirect immunofluorescence. among these women, western blot was interpreted as indeterminate in 11 (0.1%) cases and their viral load was <50 copies/ml. we found a prevalence of 0.1% hiv indeterminate western blots in pregnant women from presidente prudente and the surrounding region; none of these pregnant women had positive hiv viral loads.
