RESUMO Introdução: A queilite actínica é uma lesão inflamatória com potencial de transformação maligna e desenvolvimento associado à exposição solar excessiva. Objetivo: Avaliar a prevalência de queilite actínica em um grupo de agricultores, bem como a percepção e conhecimento desse grupo sobre a lesão. Métodos: O estudo observacional de levantamento epidemiológico envolveu uma população de agricultores de uma região do sertão brasileiro. A amostra foi obtida por acessibilidade a essa população, e alcançou-se o total de 219 agricultores. Além do exame físico intraoral, utilizou-se um questionário estruturado para coleta dos dados. Resultados: A queilite actínica foi diagnosticada em 30,6% dos agricultores examinados. A lesão foi encontrada com maior frequência no sexo masculino (86,6%), com mais de 60 anos (64,2%) e leucodermas (58,2%). A maioria dos indivíduos com queilite actínica se expunham à radiação solar por mais de 30 anos (65,7%), por mais de 6h por dia (73,1%) e não se protegiam adequadamente (94%). Sexo, idade, escolaridade, hábito de beber e tempo de exposição solar tiveram uma correlação estatisticamente significante com a presença da queilite actínica (p<0,05). Verificou-se que 76,1% dos participantes não notavam sinais e 61,2% não percebiam sintomas da lesão. O conhecimento sobre queilite actínica foi baixo para 97% dos indivíduos com lesão. Conclusões: Os resultados demonstraram alta prevalência de queilite actínica, além de uma baixa percepção e conhecimento sobre esta lesão, o que indica a necessidade de realização de ações de educação em saúde.

ABSTRACT Introduction: Actinic cheilitis is an inflammatory, potentially malignant lesion associated with excessive sun exposure. Objective: To evaluate the prevalence of actinic cheilitis in a group of farmers, as well as the perception and knowledge of that group about this lesion. Methods: The observational epidemiological study included Brazilian semi-arid region farmers. The sample was obtained for accessibility to this population and a total of 219 farmers was reached. A structured questionnaire was used to collect the data in addition to the intraoral physical examination. Results: Actinic cheilitis was diagnosed in 30.6% of the examined farmers. The lesion was found more frequently in males (86.6%), older than 60 years (64.2%), and leukoderma (58.2%). Most individuals with actinic cheilitis were exposed to solar radiation for more than 30 years (65.7%), for more than 6 hours a day (73.1%), and did not adequately protect themselves (94%). Sex, age, education level, drinking habits, and time of sun exposure had a statistically significant correlation with the presence of actinic cheilitis (p <0.05). It was found that 76.1% of the participants did not notice signs and 61.2% did not perceive symptoms of this injury. Knowledge about actinic cheilitis was low for 97% of individuals with the lesion. Conclusions: The results showed a high prevalence of actinic cheilitis, in addition to low perception and knowledge about it, which indicates the need for health education actions.

Resumo O presente trabalho visa discutir resultados de dois métodos de ensaio que avaliam propriedades da superfície de revestimentos de argamassa: resistência superficial à tração (RST) e esclerometria de pêndulo (que fornece o índice esclerométrico - IE), além de avaliar, complementarmente, a resistência de aderência à tração (RA). As variáveis estudadas foram: tipo de argamassa (preparada em obra e industrializada) e umidade do revestimento no instante do ensaio (4 teores). Para cada ensaio foram planejados no mínimo 45 determinações por situação analisada, totalizando 1411 resultados válidos, o que permitiu uma análise estatística consistente e uma discussão aprofundada dos métodos. Os ensaios RST e IE foram sensíveis, a um nível de confiança de 95%, para diferenciar argamassas de resistências distintas, ficando, portanto, credenciados para tal avaliação. O efeito mais significativo em todos os modelos estatísticos testados foi o tipo de argamassa. A variável condição de umidade do revestimento foi significativa somente para os resultados de RST e RA. Nesses casos, ensaios realizados com os revestimentos molhados ou saturados tendem a apresentar resultados de resistência muito mais baixos do que quando eles estão secos ao ar. Foi possível obter uma correlação significativa entre RST e RA, com um alto coeficiente de determinação.

Abstract The objective of this study is to discuss the results of two test methods used to evaluate rendering surface properties: the superficial tensile strength (STS) and the pendulum rebound hammer (which provides the rebound index - RI), besides evaluating, additionally, the tensile bond strength (BS). The studied variables were the type of mortar (job-site mortar and dry-mix mortar) and the render moisture at the time of testing (in four contents). For each test, a minimum of 45 determinations was planned per analyzed situation, totaling 1411 valid results, which allowed a consistent statistical analysis and an in-depth discussion of the methods. The STS and RI tests were sensitive at a 95% confidence level to differentiate mortars from different strengths and were therefore approved for this evaluation. The most significant effect in all statistical models tested was the type of mortar. The variable moisture condition of the render was significant only for the results of STS and BS. In such cases, tests performed with wet or saturated renders presented much lower strength results compared to those carried out with air- dried renders. It was possible to obtain a significant correlation between STS and BS, with a high coefficient of determination.

RESUMO: A intoxicação por Tephrosia cinerea causa fibrose hepática periacinar em ovinos na região semiárida do Nordeste, com quadro clínico de ascite acentuada, e, ocasionalmente, com sinais neurológicos. Neste trabalho foram estudadas 16 ovinos em 6 surtos de intoxicação por T. cinerea. Todos os ovinos apresentaram lesões histológicas de fibrose periacinar e seis apresentaram, no encéfalo, vacuolização da substância branca e da junção entre a substância branca e a cinzenta com presença de astrócitos de Alzheimer tipo II na substância cinzenta. A doença foi reproduzida experimentalmente em dois ovinos que apresentaram ascite, desvios vasculares (shunts) porto-sistêmicos e sinais nervosos com lesões histológicas semelhantes a dos casos espontâneos. Na técnica de imuno-histoquímica houve marcação fraca ou ausente do citoplasma astrocitário para o anticorpo anti-GFAP em seis ovinos evidenciando uma alteração degenerativa, em que os astrócitos acumulam corpos densos e reduzem o volume de GFAP. Houve marcação positiva para o anticorpo anti-S100 em oito ovinos, incluindo os dois ovinos experimentais o que sugere reatividade celular, com proliferação mitocondrial e de retículo endoplasmático liso. Estas alterações são caraterísticas dos efeitos da amônia nos astrócitos. Conclui-se que na intoxicação por T. cinerea em alguns ovinos ocorrem sinais nervosos em consequência da encefalopatia hepática.

ABSTRACT: In the semiarid region of northeastern Brazil, Tephrosia cinerea causes periacinar hepatic fibrosis in sheep with severe ascites and, occasionally, nervous signs. Sixteen sheep from six outbreaks of T. cinerea poisoning were studied. All sheep had histologic lesion of periacinar fibrosis and six showed, in the brain, vacuolization (spongy degeneration) of the white matter and junction between grey and white matter and presence of Alzheimer type II astrocytes in the grey matter. The disease was produced experimentally in two sheep, that presented porto-sistemic shunts and similar histologic lesions as those observed in the spontaneous cases. Immunohistochemistry revealed weak labelling with anti-GFAP antibodies suggesting a degenerative alteration of astrocytes with accumulation of dense bodies and reduction of the GFAP. There was strong labelling with anti-S100 antibodies suggesting cellular reactivity with proliferation of mitochondria and endoplasmatic reticulum. Such alterations are characteristic of the effects caused by ammonia on the astrocytes. It is concluded that in poisoning by T. cinerea nervous signs due to hepatic encephalopathy occur in some sheep.

This paper describes the development, evaluation, features and applications of Chromophoreasy, an alternative Excel-based program for recognition and integration of chromatographic and electrophoretic peaks. The proposed recognition is made according to parameters adjustable by the analyst, such as time range, noise smoothing window size and slope/curvature sensitivity. During integration, retention/migration time, area, height, half-height width, plate numbers, asymmetry factor, US Pharmacopeia tailing factor, resolution and statistical moments are determined. A chromatogram/electropherogram is plotted along with the found baselines. The effect of peak shape (heights and symmetries) and baseline slope over accuracy was evaluated and the precision of recognition/integration was investigated under several simulated conditions, with varied signal-to-noise levels, smoothing modes and smoothing window sizes. Data from liquid and gas chromatography, capillary electrophoresis and electrochromatography techniques with refractive index, flame ionization, capacitively coupled contactless conductivity (lab-made) and ultraviolet absorbance detections, respectively, were treated, illustrating the broad applicability of the proposed program for standard and sample analysis. Statistically similar results were obtained, when compared with other commercial software, showing it to be a simple, practical and reliable tool for general use in the separation area.

<p>Among the analytical separation techniques, capillary electrophoresis (CE) has attracted attention in both academic and industrial fields, mainly owing to its efficiency, short analysis times, low reagent consumption and residue generation. This is also the case in Chemistry courses, books and papers, demonstrating CE´s well-established status. However, despite the range of available bibliographic material, there is a lack of animations showing the CE dynamic process. Therefore, the aim of this work was to show the development of a group of animations available for public access, where electrolyte and analytes movements under different CE modes; electropherogram formation; and online ultraviolet-visible spectra can be viewed. The normal or reverse electroosmotic flow generation in the vicinity of the silica capillary wall and the partition motion of neutral compounds between micellar and aqueous phases are also shown. Capillary zone electrophoresis, micellar electrokinetic chromatography, capillary electrochromatography, capillary isoelectric focusing, capillary isotachophoresis and capillary gel electrophoresis, are included in this package. This animation approach can be highly didactic and can complement the theoretical study of CE techniques, which may aid researchers, teachers and students interested in understanding the dynamism and potential of different CE modes.</p>

A monolithic stationary phase based on 3-(methacryloxypropyl)trimethoxysilane monomer, prepared within a fused silica capillary externally coated with a UV-transparent fluoropolymer was employed for separation of estriol, 17-b-estradiol and progesterone by capillary electrochromatography in a standard mixture. A 23 factorial design was used to optimize the separation system. The optimized condition containing 30% (v/v) of acetonitrile and 10 mmol L-1 aqueous ammonium acetate presented a total run time less than 10 min by applying 25 kV. The resolution between adjacent peaks ranged from 1.8 up to 2.9 and the plate numbers per column meter in this condition was 1873, 3631 and 3886 for the estriol, 17-b-estradiol and progesterone peaks, respectively. The optimized method was employed in the quantitative analysis of a commercial transdermal emulsion formulation.

The filling of capillaries via the sol-gel process is growing. Therefore, this technical note focuses on disseminating knowledge acquired in the Group of Analytical Chemistry and Chemometrics over seven years working with monolithic stationary phase preparation in fused silica capillaries. We believe that the detailed information presented in this technical note concerning the construction of an alternative high pressurization device, used to fill capillary columns via the sol-gel process, which has promising potential for applications involving capillary electrochromatography and liquid chromatography in nano scale, may be enlightening and motivating for groups interested in developing research activities within this theme.

Purpose To report long-term results of the Argus T adjustable system for treatment of post-prostatectomy urinary incontinence (PPI). Materials and Methods From October 2007 to August 2008, 37 patients with PPI were included in a prospective, single-arm, multicenter trial of treatment with the Argus T adjustable system (Promedon, Argentina). Preoperative evaluation included urine culture, urethrocystoscopy, urodynamic testing, 24-h pad weight test (PWT) and quality of life questionnaires. Patients were stratified according to baseline degree of incontinence (mild–moderate or severe). Postoperative evaluation included immediate PWT, quality of life questionnaires and daily use of pads at 1, 12 and 30 months. Results and Conclusions One patient was lost to follow-up. At the 30-month follow-up, 24/31 patients (77%) were dry, 3/31 (10%) improved and 4/31 (13%) were failures. In particular, in the mild-moderate group, 8/8 (100%) patients were dry. In the severe group, 20/28 patients (71%) were dry, 3/28 (11%) improved and 5/28 (18%) were failures. Median visual analogue scale (VAS) scores dropped from 9 (4-10) to 0.5 (0-10) and International Consultation on Incontinence Questionnaire Short Form scores from (ICIQ-SF) 19 (12–21) to 1 (0–10). Retrograde leak point pressure increased from 18 (5–29) to 35 (22–45) cm H2O after intraoperative adjustment. Complications included immediate postoperative infection in 2/36 patients (6%) and transient inguinal and/or perineal pain in 22/36 patients (61%). Argus T has a long-term high success rate (86% cure + improvement at the 30-month follow-up). Good outcomes were achieved even in severe incontinence cases and maintained for over 30 months.

Introduction and Objective: Some candidates for brachytherapy present with a previous history of prostate transurethral resection (TURP). Nonetheless, TURP generates a cavity that may lead to technical difficulties in performing brachytherapy. Such condition make a history of previous TURP a relative contra-indication for brachytherapy. The aim of this study is to evaluate the role of brachytherapy in urinary continence, in a group of patients with previous history of TURP. Materials and Methods: In our study, we analysed a group of 16 patients submitted to TURP pre-brachytherapy. The mean quality of life score from ICSmaleSF questionnaire ranged from 0 to 1 before and after brachytheraphy (average: 0,18 -before; average: 0,20 - after). There was no estatistically significant difference between the former values (p< 0,001). After brachytherapy patients were evaluated for lower urinary tract symptoms. The time interval between TURP and brachytherapy ranged from 30 to 90 days (average: 60 days). Post-brachytherapy follow-up varied between 3 and 60 months (average: 30 months). Results: None of the 16 patients evaluated presented lower urinary tract symptoms nor urinary incontinence. Medical complications observed in patients were: dysuria, erectile dysfunction, scrotal ecchymosis and urinary retention . The cases of dysuria, scrotal ecchymosis and urinary retention observed were of short-duration, the last one with spontaneous resolution after 7 days of vesical catheterism. The patient presenting erectile dysfunction had a good response to oral type 5 fosfodiesterase inhibitor three times a week, after a six month period. Conclusion: In accordance with other studies, we believe that with some strategy TURP should not be considered a relative contra-indication for brachytherapy.

Introducción y objetivos: Algunos de los pacientes candidatos a la braquiterapia presentan historia previa de resección transuretral de la próstata (RTUP). La RTUP, sin embargo, crea una cavidad que puede llevar a algunas dificultades técnicas para la realización de braquiterapia. Tales condiciones tornan a la RTUP, previa a la braquiterapia, una contraindicación relativa a la realización de ésta. El objetivo del presente trabajo es evaluar las tasas de incontinencia urinaria en pacientes submetidos a braquiterapia despues de una RTUP por medio de análisis retrospectiva. Materiales y métodos: En nuestro estudio analizamos 16 pacientes sometidos a RUTP previa a braquiterapia. Tras braquiterapia los pacientes fueron evaluados sobre síntomas del tracto urinario inferior a través del cuestionario ICSmaleSF. El intervalo de tiempo entre la RTUP y el tratamiento braquiterápico varió de 30 a 90 días, (media= 60 días). El seguimiento post braquiterapia varió entre 3 a 60 meses, (media= 30 meses). Resultados: Ninguno de los 16 pacientes evaluados presentó síntomas del tracto urinario inferior o incontinencia urinaria. Con el cuestionario ICSmaleSF la puntuación de interferencia en la calidad de vida obtuvo una media de 0,18 antes de la braquiterapia (variando de 0 a 1) y después de la braquiterapia de 0,20 (variando de 0 a 1) (p< 0,001), donde las diferencias de los resultados no fue estadísticamente significativa. Algunas complicaciones fueron observadas como: disfunción eréctil, equimosis escrotal y retención urinaria. Los casos de disuria, equimosis escrotal y retención urinaria fueron de corta duración y resolución espontánea, éste último tras cateterismo vesical por 7 días. El paciente portador de disfunción eréctil presentó buena respuesta al uso semanal (3x/semana) de inhibidor de fosfodiesterasa tipo 5, después de un periodo de 6 meses. Conclusión: En concordancia con otros estudios, nosotros creemos que con alguna estrategia la RTUP no debería ser considerada una contraindicación relativa para la braquiterapia.

Objective: To communicate long- term results of the multicentre phase III trial post-prostatectomy urinary incontinence (PPI) treated with an adjustable male sling¹. Patients and Methods: 48 PPI patients were included in this trial from april 2003 to september 2004. 39 post radical prostatectomy and 9 post adenomectomy. 19 wore 5 pads per day (3-8) each weight 83gr (17-198). 29 wore condom catheter or penile clamp. The Argus was implanted through perineal approach. Using needles, the sling was transferred to the abdominal wall where it was adjusted by washers. The adjustment was done with retrograde urethral pressure from 45 to 55 cm water. Clinical data were up-dated till September 2007. The mean follow-up was 45 months (36-54) and median age was 67 years (52-77). The evaluation was: the ICIQ-SF score and qualification as Dry: no pads, Improved: 1 pad and Failed: 2 or more pads in 24 hr, including those with slings removed. Results: 47 were evaluated, resulting: 31 (66%) Dry, 6 (12.8%) Improved and 10 (21%) Failed. The ICIQ-SF score changed from 19.5 to 6. Of the 31 dry pts, 5 required one adjustment. 10 pts failed, 9 after sling removal, 6 due to erosion and 3 for infection. One patient failed with the sling in place, 6 erosions were registered: 4 in the urethra, 1 into the bladder and 1 through the abdominal wall. Perineal pain persisted in 2. One patient was excluded, died in September 2006. Conclusions: Argus® has demonstrated its efficacy in long- term follow-up. The social continence rate was about 80%. The important complication was erosion or infection.

Pacientes y métodos: 48 pacientes con IPP, 39 post radical y 9 post adenomectomía, ingresaron entre abril de 2003 y septiembre de 2004. 19 usaban 5 paños por día (3-8) pesando 83 gr. (17-198) por paño. 29 usaban clamp peniano o colector externo. El seguimiento promedio fue de 45 meses (36-54). La edad fue de 67 años (52-77). Fueron evaluados con el cuestionario ICIQ-SF y la calificación de seco (sin paños), mejora (1 paño) y falla (2 o más paños en 24 hs), incluyéndose a los slings extraídos. El Argus se implantó por vía perineal, transfiriéndolo con agujas al abdomen para ser ajustado y fijado con arandelas. El ajuste se realizó por presión uretral retrograda (PUR) entre 45 y 55cm de agua. Resultados: Evaluamos 47 de 48 pacientes (1, falleció antes de 3 años) resultando secos, mejorados y fallados, 31(66%), 6 (12.8%) y 10 (21%) respectivamente. ICIQ-SF cambió de 19,5 a 6 (1-21). 5 de 31 secos, debieron reajustarse una vez. Fallaron 10 pacientes: 9 Argus retirados: 6 (12,8%) por erosión, 3 (6,2%) por infección y 1 usa 3 paños diarios. Hubieron 6 erosiones: 4 uretrales, 1 vesical y 1 parietal abdominal. El dolor persistió en 2 casos. Las complicaciones menores se resolvieron espontáneamente antes de 2 meses. Conclusiones: El Argus® demostró ser eficaz en el control de la IPP en el largo plazo en casi el 80% de los pacientes evaluados. La infección y la erosión fueron las complicaciones más importantes y los desafíos a resolver.

The assembly of a photochemical reactor with six fluorescent lamps, used for photopolymerizations is described. This chamber presents a mobile support, allowing the placement of samples at different heights and a safety lock that interrupts the radiation, if it is opened during operation. The mirrored internal walls avoid the dispersion and non-uniform distribution of light. There is no high heating because the own character of the used lamps. All parts could be purchased in commerce with less than U$ 150,00. This reactor was successfully used for monolithic stationary phase photopolymerization.

OBJETIVO: A cirurgia de sling pubovaginal é utilizada no tratamento da incontinência urinária de esforço (IUE) do tipo III e como resgate na falha de procedimentos anteriores. Tem índice de sucesso variando de 73 a 89%. Podem ser utilizados diversos materiais autólogos e sintéticos com semelhantes resultados. Nosso objetivo foi comparar o sling de parede vaginal com o de fáscia do reto abdominal quanto à eficácia e às complicações. MÉTODO: Foram estudadas 27 pacientes no período de 04/98 a 09/00, divididas em dois grupos: grupo I com nove pacientes submetidas a sling de parede vaginal; grupo II com 18 pacientes submetidas a sling de fáscia do reto abdominal. Todas foram submetidas a um estudo urodinâmico completo, classificadas quanto ao tipo de IUE, e seguidas no ambulatório de urologia. RESULTADOS: grupo I com média de idade de 51,4 anos, tempo de seguimento médio de 14,3 meses. Pressão de Perda aos Esforços (PPE) variando de 50 a 100cmH2O com média de 81,1cmH2O. Houve 66% de complicações. Taxa de sucesso de 88,8% e índice de satisfação 85 pontos. Grupo II com média de idade de 54,2 anos, seguimento médio de 19,3 meses. PPE variando de 45 a 92cmH2O, média de 65,5cmH2O. Houve 72% de complicações e sucesso de 88,8%. Índice de satisfação de 74 pontos. CONCLUSÕES: Os dados encontrados estão de acordo com a literatura, sendo os dois grupos comparáveis quanto à eficácia em período curto de seguimento. O grupo II apresentou maior número de complicações, assim como maior tempo de cateter vesical e menor índice de satisfação geral.

BACKGROUND: Pubovaginal sling is being currently used for the treatment of type III Stress Urinary Incontinence (SUI) and for recurrences after previous procedures. Success rates vary from 73 to 89%. Many autologous and allogênic materials have being used with a variable rate of complications. Our objective was to compare the vaginal wall sling to the rectus fascia pubovaginal sling concerning effectiveness and complications. METHOD: Twenty seven patients submitted to pubovaginal sling between 04/98 and 09/00 were divided into two groups: Group I includes 9 patients submitted to vaginal wall sling while Group II with 18 patients submitted to rectus fascia pubovaginal sling. All patients underwent a complete urodinâmic study. They were classified according to the type of SUI and followed at the urology clinic where complications and patient satisfaction index were registered. RESULTS: Group I: The mean age was of 51.4 years. The a mean follow-up period was 14,3 months. The Valsalva leak point pressure (VLPP) varied from 50 to 100cmH2O, with a mean pressure of 81.1cmH2O. Six patients (66%) presented postoperative complications. Curative rate was 88.8% and patient satisfaction index was 85 points. Group II: The mean age was of 54.2 years; the mean follow-up period was 19,3 months. The VLPP varied from 45 to 92cmH2O, with a mean pressure of 65,5cmH2O. Thirteen patients (72%) presented postoperative complications. The curative rate was 88.8% and the patient of satisfaction index was 74 points. CONCLUSIONS: Both techniques have a comparable effectiveness during a short follow-up period. The use of rectus fascia pubovaginal sling was associated with more postoperative complications, longer urethral catheterization and lawer patient satisfaction index.

Este trabalho descreve uma metodologia para a regeneração de plantas de tangerina 'Cleópatra' e limão 'Cravo', a partir do cultivo de protoplastos de suspensão celular. Para tal, calos nucelares foram induzidos em meio contendo BAP e cultivados em meio sem reguladores de crescimento. Protoplastos foram isolados de suspensões celulares e cultivados em gotas de agarose, com densidade de 2 X 105 protoplastos.ml-1. O meio MT, contendo ácido giberélico e água de coco, foi eficiente na germinação de embriões somáticos. Os métodos de aclimatação de plantas testados apresentaram baixa eficiência. Como resultado final, 17 plantas adaptadas de tangerina e 8 de limão foram obtidas.

The present research describes the regeneration of 'Cleópatra' mandarin and 'Rangpur' lime plants from cell suspension protoplasts. Nucelar calli were induced on a medium containing BAP and maintained on growth regulator free medium. Protoplasts were isolated from embryogenic suspension and plated at a concentration of 2 X 105 protoplasts.ml-1, on agarose droplets. The MT medium with gibberellic acid and coconut water was efficient to stimulate somatic embryo conversion. Rooted plants acclimation had low efficiency. Seventeen mandarin plants and eight lime plants were obtained.
