RESUMO O tambaqui (Colossoma macropomum) é um dos peixes de água doce mais produzidos na piscicultura brasileira. No entanto, sua eficiência produtiva associada ao refinamento das formulações de dietas é limitada devido à falta de informações sobre as exigências nutricionais de determinados aminoácidos essenciais, como a valina. Objetivou-se estimar a exigência de valina para o tambaqui com diferentes pesos corporais. Um total de 720 juvenis foi utilizado nos experimentos, o primeiro com 360 peixes com peso médio inicial de 33,28 ±0,19 g e o segundo com 360 peixes (121,19 ±1,29 g). Os experimentos foram conduzidos em dose-resposta com cinco níveis de valina (5,0; 7,0; 9,0; 11,0 e 13,0 g/kg de dieta) e quatro repetições por tratamento. A dieta controle foi obtida pela adição de L-valina à dieta contendo 5,0 g/kg de dieta (primeiro nível de valina testado), de modo que atingiu a dieta contendo 7,0 g/kg de dieta, correspondente ao segundo nível testado. Foram realizados análise de variância dos dados, teste de Dunnett’s para comparação com dieta controle e análise de regressão. Os resultados para a ingestão de valina, ganho de peso, taxa de crescimento específico, taxa de conversão alimentar foram significativamente melhorados pela valina dietética (P<0,05) em ambos os experimentos. Os níveis dietéticos de valina exerceram efeitos quadráticos sobre a proteína corporal, gordura corporal, deposição de proteína corporal e eficiência de retenção de nitrogênio do tambaqui com 33 g e 121 g, sendo a deposição de gordura corporal afetada pelo nível de valina somente no tambaqui com 33 g. Com base na análise de regressão quadrática dos dados de deposição de proteína corporal, as exigências dietéticas de valina de tambaqui (33,0 g-83,0 g) e (121,0 g-277,0 g) foram estimadas em 11,9 g/kg da dieta e 9,1 g/kg da dieta, respectivamente.

ABSTRACT Tambaqui (Colossoma macropomum ) is one of the highly produced freshwater fish in Brazilian fish farming. However, its production efficiency associated with the refinement of diet formulations is limited due to a lack of information on nutritional requirements for certain essential amino acids such as valine. This study was designed to estimate the valine requirement of tambaqui having different body weights. A total of 720 juveniles were used in the feed trials. The first trial consisted of 360 fish with an average initial weight of 33.28 ±0.19 g, and the second trial comprised 360 fish (121.19 ±1.29 g). The trials consisted of dose-response experiments with five levels of valine (5.0, 7.0, 9.0, 11.0, and 13.0 g/kg diet) and four replicate tanks per treatment. The control diet was obtained by adding L-valine to the diet containing 5.0 g/kg diet (the first level of valine tested) to ensure it reached the diet containing 7.0 g/kg diet, corresponding to the second level tested. Analysis of variance, Dunnett’s test for comparison with the control diet, and regression analysis were performed. The results showed that the valine intake, weight gain, specific growth rate, and feed conversion ratio were significantly improved by the dietary valine (P < 0.05) in both trials. Dietary levels of valine exerted quadratic effects on body protein, body fat, body protein deposition, and nitrogen retention efficiency of tambaqui with 33 g and 121 g as body fat deposition was affected by the dietary valine level only in tambaqui weighing 33 g. Quadratic regression analysis of body protein deposition data revealed the optimum dietary valine requirement of tambaqui (33.0 g-83.0 g) and (121.0 g-277.0 g) as 11.9 g/kg diet and 9.1 g/kg diet, respectively.

The in vitro biological tests of solar photoprotection and antiradical activities against the crude extract and Hex and AcOEt fractions showed relevant results, which confirm the high pharmaceutical potential of the species.

Resumo O tratamento da esquistossomose é dependente de uma única droga, praziquantel (PZQ). O desenvolvimento da resistência de PZQ tem atraído atenção de muitos pesquisadores por medicamentos alternativos. Um tratamento viável e promissor é o estudo das plantas medicinais como uma nova abordagem para o tratamento experimental para esquistossomose. O presente trabalho objetivou avaliar a atividade esquistossomicida in vivo óleo essencial de Mentha x villosa (OE-Mv) e rotundifolona (ROT) contra Schistosoma mansoni. Foram utilizados camundongos Swiss webster (Mus musculus) fêmea de trinta dias de idade pesando 50 gramas. Os camundongos foram infectados com 80 cercárias de S. mansoni (cepa BH) e administrado por via oral OE-Mv (50, 100 e 200 mg/Kg) e ROT (35,9, 70,9 e 141,9 mg/Kg) apos 45 dias de infecção durante 5 dias consecutivos. Todos os animais foram eutanasiados 60 dias após a infecção. Praziquantel foi o controle positivo no experimento. O tratamento dos camundongos infectados com doses de 200 mg/kg (OE-Mv) e rotundifolona (141,9 mg/Kg) resultaram em redução significativa dos vermes (72.44% e 74.48%, respectivamente). Foi observado também redução no fígado, intestino e fecal e alteração no padrão do oograma, em comparação aos camundongos infectados e não tratados. Considerando os resultados obtidos, mais estudos biológicos são necessários a fim de elucidar o mecanismo de ação esquistossomicida contra adultos de S. mansoni.

Abstract Schistosomiasis treatment is dependent on a single drug, praziquantel (PZQ). The development of resistance of PZQ has drawn the attention of many researchers to alternative drugs. One viable and promising treatment is the study of medicinal plants as a new approach to the experimental treatment for Schistosomiasis. The present work aimed to evaluate in vivo antischistosomal activity of effect of Mentha x villosa Oil Essential (Mv-EO) and rotundifolone (ROT) against Schistosoma mansoni. Thirty-day-old female Swiss webster mice (Mus musculus) weighing 50 grams were used. Mice were infected with 80 cercariae of S. mansoni (BH strain) and orally administered Mv-EO (50, 100 and 200 mg/Kg) and ROT (35.9, 70.9 and 141.9 mg/Kg) at 45-days post infection for 5 consecutive days. All mice were euthanized 60 days after infection. Praziquantel was the positive control in the experiment. Doses of 200 mg/kg (Mv-EO) and ROT (141.9 mg/Kg) resulted in a significant reduction in fluke burden (72.44% and 74.48%, respectively). There was also marked reduction in liver, intestinal and faecal and changed oogram pattern, compared to infected untreated mice. Considering the results obtained, further biological studies are required in order to elucidate the mechanism of schistosomicidal action on against adult S. mansoni.

Introduction: Schistosomiasis is a chronic disease caused by trematode flatworms of the genus Schistosoma and its control is dependent on a single drug, praziquantel (PZQ), but concerns over PZQ resistance have renewed interest in evaluating the in vitro susceptibility of recent isolates of Schistosoma mansoni to PZQ in comparison with well-established strains in the laboratory. Material and methods: The in vitro activity of PZQ (6.5-0.003 µg/mL) was evaluated in terms of mortality, reduced motor activity and ultrastructural alterations against S. mansoni. Results: After 3 h of incubation, PZQ, at 6.5 µg/mL, caused 100% mortality of all adult worms in the three types of recent isolates, while PZQ was inactive at concentrations of 0.08-0.003 µg/mL after 3 h of incubation. The results show that the SLM and Sotave isolates basically presented the same pattern of susceptibility, differing only in the concentration of 6.5 µg/mL, where deaths occurred from the range of 1.5 h in Sotave and just in the 3 h range of SLM. Additionally, this article presents ultrastructural evidence of rapid severe PZQ-induced surface membrane damage in S. mansoni after treatment with the drug, such as disintegration, sloughing, and erosion of the surface. Conclusion: According to these results, PZQ is very effective to induce tegument destruction of recent isolates of S. mansoni.

The chemical composition of the essential oil obtained from the fresh and dried leaves of Lippia gracillis Schauer, Verbenaceae, was analyzed by gas chromatography and gas chromatography/mass spectrometry (GC⁄MS). The yield of essential oil extracted from the dried leaves was significantly higher (p<0.05) when compared to the fresh leaves. Seventeen components were identified. The monoterpenes and sesquiterpene hydrocarbons with 96.26% (w/w) of the total oil obtained of fresh leaves and 86.99% (w/w) of the total oil obtained of dried leaves were the principal compound groups. Thymol was observed dominant (44.42%; 21.3%), followed by carvacrol (22.21%; 21.30%), p-cymene (6.23%; 8.58%), α-pinene (5.65%; 19.42%), β-caryophyllene (5.61%; 3.57%) and other minor constitutes, respectively. Microbiological results obtained by agar diffusion method, micro dilution method and minimum inhibitory concentration (MIC) showed that the essential oil has a relevant antimicrobial activity against E. coli (ATCC 10536), E. coli (Ec 27), Pseudomonas aeruginosa (ATCC 15442), S. aureus (ATCC 12692) and S. aureus (Sa 358), with their inhibition zones ranging from 9 to 13 mm and the MIC ranging from 64 to 512 μg/mL.

CONTEXTO: Como a anoretocele está sempre associada a prolapso mucoso e/ou intussuscepção retal, foi desenvolvida uma técnica cirúrgica grampeada, utilizando somente um grampeador mecânico. OBJETIVO: Demonstrar os resultados do estudo multicêntrico que realizou o tratamento cirúrgico de pacientes com anorretocele associado a prolapso mucoso, utilizando o reparo transanal da retocele e mucosectomia com grampeador circular mecânico. MÉTODO: Foram incluídos 75 pacientes, média de idade 49,6 anos, com sintomas de evacuação obstruída, apresentando escore médio de constipação de Wexner de 16 e diagnóstico de anorretocele grau II (26.7%), grau III (73,3%) associado a prolapso mucoso e intussuscepção (52%). Todos foram avaliados com exame proctológico, defecografia, manometria anorretal e tempo de trânsito colônico. O procedimento cirúrgico foi realizado por 14 cirurgiões e consiste na remoção manual da parede do reto no local da retocele e mucosectomia circunferencial com um grampeador circular mecânico. O seguimento médio foi de 21 meses. RESULTADOS: Os pacientes apresentavam sintomas de evacuação obstruída, mesmo após tratamento clinico. O tempo operatório médio foi de 42 minutos. Houve sangramento transanal na linha de sutura em 13 (17,3%) pacientes, sutura grampeada incompleta em 2 (2,6%) e dor retal persistente em 3 (4,0%). O tempo médio de internação hospitalar foi de 1 dia em 49 (65,3%) e 2 dias em 34,7%. Ocorreu redução na linha de sutura em 7 (9,3%), sendo necessário estricturotomia cirúrgica sob anestesia (n = 1), utilizando "hot biopsy" (n = 3) e dilatação anal (3). Defecografia no pós-operatório demonstrou anorretocele residual grau I em 8 (10.6%). O escore de constipação de Wexner reduziu 16 para 4 (0-4: n = 68) (6: n = 6) (7: n = 1) (P<0.0001). CONCLUSÃO: O resultado do estudo multicêntrico demonstrou que a técnica cirúrgica apresentada é segura e efetiva para tratamento da anorretocele associada a prolapso mucoso. Apresenta baixo custo pois utiliza um grampeador circular mecânico.

CONTEXT: Since anorectocele is usually associated with mucosa prolapse and/or rectal intussusceptions, it was developed a stapled surgical technique using one circular stapler. OBJECTIVE: To report the results of Transanal Repair of Rectocele and Rectal Mucosectomy with one Circular Stapler (TRREMS procedure) in the treatment of anorectocele with mucosa prolapse in a prospective multicenter trial. METHODS: It was conducted by 14 surgeons and included 75 female patients, mean aged 49.6 years, with symptoms of obstructed defecation due to grade 2 (26.7%) and grade 3 (73.3%) anorectocele associated with mucosa prolapse and/or rectal intussusception (52.0%) and an average validated Wexner constipation score of 16. All patients were evaluated by a proctological examination, cinedefecography, anal manometry and colonic transit time. The TRREMS procedure consists of the manual removal of the rectocele wall with circumferential rectal mucosectomy performed with a circular stapler. The mean follow-up time was 21 months. RESULTS: All patients presented obstructed defecation and they persisted with symptoms despite conservative treatment. The mean operative time was 42 minutes. In 13 (17.3%) patients, bleeding from the stapled line required hemostatic suture. Stapling was incomplete in 2 (2.6%). Forty-nine patients (65.3%) required 1 hospitalization day, the remainder (34.7%) 2 days. Postoperatively, 3 (4.0%) patients complained of persistent rectal pain and 7 (9.3%) developed stricture on the stapled suture subsequently treated by stricturectomy under anesthesia (n = 1), endoscopic stricturectomy with hot biopsy forceps (n = 3) and digital dilatation (n = 3). Postoperative cinedefecography showed residual grade I anorectoceles in 8 (10.6%). The mean Wexner constipation score decreased significantly from 16 to 4 (0-4: n = 68) (6: n = 6) (7: n = 1) (P<0.0001). CONCLUSION: Current trial results suggest that TRREMS procedure is a safe and effective technique for the treatment of anorectocele associated with mucosa prolapse. The stapling technique is low-cost as requires the use of a single circular stapler.

Este relato apresenta o seguimento tardio de um caso de cardiomiopatia de Takotsubo com boa evolução clínica e melhora da função sistólica global ventricular esquerda. Contudo, observou-se persistência de significativa disfunção sistólica regional longitudinal que foi avaliada por meio de nova técnica ecocardiográfica (speckle tracking), com as medidas do strain (S) e strain rate (SR) correspondentes. Ressaltamos a importância desse novo método para o acompanhamento dessa cardiopatia, pois permite identificar os pacientes que persistem com disfunção sistólica e que possivelmente serão beneficiados com a manutenção da terapêutica clínica.

This report presents the late follow-up of a case of Takotsubo cardiomyopathy with good clinical outcome and improved left ventricular global systolic function. However, there was persistence of significant regional longitudinal systolic dysfunction evaluated using a new echocardiographic technique (speckle tracking), with corresponding measures of strain (S) and strain rate (SR). We emphasize the importance of this new method to monitoring this cardiomyopathy, since it identifies patients with persistent systolic dysfunction who will possibly benefit from maintenance of clinical therapy

Customized refractive surgery means adapting treatment to the patient according to the corneal characteristics and correcting defects that affect the quality of vision, for example, optical aberrations. Twenty one eyes from 13 patients with residual myopia after undergoing radial keratotomy were selected. Visual acuity without correction and also, keratometry, dynamic refraction, cycloplegic refraction, corneal topography, tachymetry, tonometry, biomicroscopy, study of the tear and funduscopy were performed. All the eyes were applied the sofware for analysis of corneal wavefront and Lasik (Queratomileusis in situ with laser) and optimized refractive keratectomy were performed. Visual acuity without correction changed from 0.17 to 0.75. Average sphere equivalent varied from -4.81 D to -0.67 D. Higher-order aberrations before and after surgery changed from 0,970 um to 1,130 um. Visual acuity without correction was over 0.8 in all the cases after Lasik surgery. Spheral equivalent and cylindrical component of the eyes were reduced. Total aberrations decreased in all the cases.

La agudeza visual sin corrección varió de 0,17 a 0,75. El equivalente esférico promedio se modificó de -4,81 D a -0,67 D. Las aberraciones de alto orden (HORMS) prequirúrgicas y posquirúrgicas variaron de 0,970 um hasta 1,130 um. La agudeza visual sin corrección fue superior a 0,8 en todos los casos después de la cirugía de Lasik. Disminuyó el equivalente esférico y el componente cilíndrico en todos los ojos. Las aberraciones totales disminuyeron también en todos los casos.

Entre 147 espécimes respiratórios (114 escarros e 33 swabs faríngeos) coletados de 36 portadores de fibrose cística durante consultas de rotina ou na exacerbação de seus sintomas respiratórios, no período de dezembro de 2000 a dezembro de 2002, isolaram-se: Pseudomonas aeruginosa (65,3%), Staphylococcus aureus (29,9%), Burkholderia cepacia (29,2%) e Haemophilus influenzae (20,4%). Entre os isolados de S. aureus e H. influenzae, 6,8% foram resistentes à oxacilina e 6,7% foram produtores de beta-lactamase, respectivamente. Das 96 linhagens de P. aeruginosa encontradas, 59,4% foram do fenótipo mucóide. Em 12 espécimes, ambos os biótipos, mucóide e não-mucóide, estiveram presentes. Bactérias gram-negativas emergentes, tais como Stenotrophomonas maltophilia e Achromobacter xylosoxidans, foram isoladas em pequeno número. Com exceção do H. influenzae, mais freqüente nas crianças entre seis e 12 anos, não se encontrou diferença entre espécie bacteriana isolada e grupo etário.

Of 147 respiratory specimens (114 sputum and 33 pharyngeal swabs) collected from 36 cystic fibrosis patients during routine visits or exacerbation of their respiratory symptoms, from December 2000 to December 2002, the following bacterial species were recovered: Pseudomonas aeruginosa (65.3%), Staphylococcus aureus (29.9%), Burkholderia cepacia (29.2%), and Haemophilus influenzae (20.4%). Among the S. aureus and H. influenzae isolates, 6.8% were oxacillin resistant and 6.7% were beta-lactamase producers, respectively. Of 96 isolates of P. aeruginosa, 59.4% belonged to the mucoid phenotype. Both mucoid and non-mucoid morphotypes were simultaneously found in 12 specimens. Emerging gram-negative bacteria, such as Stenotrophomonas maltophilia and Achromobacter xylosoxidans, were present at a low number. H. influenzae was more prevalent in the cystic fibrosis children between six and 12 years old. Concerning the other bacterial species there was not preference for age groups.

OBJETIVO: Verificar, do ponto de vista clínico e morfológico, o efeito da chalcona na conjuntivite alérgica induzida por ovalbumina em cobaias. MÉTODOS: Utilizaram-se 54 cobaias, albinos, machos pesando aproximadamente 400 g. Os animais foram sensibilizados por injeção intraperitoneal de ovalbumina suspensa em solução adjuvante completa de Freund. Posteriormente, a conjuntivite alérgica foi induzida por instilação de ovalbumina no saco conjuntival do olho direito. Os animais foram distribuídos em 3 grupos, conforme o tratamento proposto: chalcona, corticóide e salina. A avaliação clínica foi realizada com 5, 10 e 40 min, 7 e 24 h da indução e diariamente até o dia 7 da indução. A avaliação morfológica consistiu em avaliar edema, necrose, vascularização e exocitose nos dias 1, 3 e 7 da indução. RESULTADOS: Em todos os grupos a resposta inflamatória foi mais intensa 24 h após a indução. No grupo chalcona evidenciou-se menos sinais inflamatórios que no grupo salina. O grupo corticóide apresentou menos sinais inflamatórios quando comparados aos grupos chalcona e controle. À análise morfológica evidenciou-se que os grupos chalcona e corticóide apresentaram efeitos terapêuticos semelhantes. CONCLUSÃO: A chalcona teve efeito terapêutico na conjuntivite alérgica induzida por ovalbumina.

PURPOSE: To study for clinical and morphological point of views, the effects of a chalcone in allergic conjunctivitis induced by ovalbumim in guinea pig. METHODS: Fifty-four white male guinea pigs weighing approximately 400 g were used in the study. All animals were sensitized by intraperitoneal injection of ovalbumin suspended in Freund’s complete adjuvant solution. Conjunctivitis was induced by the ovalbumin by instillation of ovalbumin in conjunctival sac of right eye´s. The animals were randomized in 3 groups agreement with the proposed treatment: chalcone,corticoid and saline. The clinical analysis were recorded at 5, 10 e 40 min, 7 e 24 h after induced and daily until 7 days after induced. Morphologic analysis consisted in evaluating edema, necrosis, vascularization and exocytosis at the 1, 3 and 7 days following induction of conjunctivitis. RESULTS: Clinical alterations were more accentuated 24 h after induction. Inflammatory signs were less apparent in chalcone group as compared to saline Corticoid group presented less inflammatory signs when compared to chalcone and control groups. Morphologic analysis disclosed that chalcona effect is similar to corticoid effects. CONCLUSION: It is concluded that chalcona had therapeutic effect in the allergic conjunctivitis induced by ovalbumine in guinea pigs.

A simplified method is used to determine the optimum water content in the flue gases of charcoal gasifiers to be utilized as alternative fuels in the operation of engines and gas turbines for power generation. Computational models of plug flow reactors and well stirred reactors are employed to simulate the reaction and post-flame zones, adopting different chemical mechanisms. In the simulations reactants enter the reactors at 1000 K, 1 atm and equivalence ratio 0.25. It was observed that mixtures about 3% to 4% in volume of water vapor allow to obtain optimal operation characteristics, including high blowout limit, low ignition delay, maximum reaction zone temperature, high CO2 prodution and low thermal NO formation. It was observed that increasing water contents reduce significantly ignition times up to 3% in volume, while blowout mass flow rates increase continuously up to 6 % in volume, the maximum value considered. Formation of NO decreases continuously with humidity after the flame zone, while there are peaks of NO formation within the flame zone below 1% in volume. Higher water vapor content decreases the final temperatures below 1700 K, leading to a lower thermal efficiency. The method can be used to estimate optimum operational conditions with other input parameters.

Neste trabalho, um modelo de percolação química (CPD), desenvolvido para o cálculo da evolução dos produtos de pirólise de partículas de carvão, foi estendido de forma a ser empregado em regimes de degradação térmica sobre a influência de campos acústicos de alta intensidade, típicos de combustores do tipo tubo de Rijke. As oscilações acústicas incrementam os processos de transferência de calor e massa no leito de combustível, bem como na região livre acima do mesmo. Os resultados obtidos em simulações com um combustor do tipo Rijke mostraram um aumento nas taxas de evaporação de água e de degradação térmica das partículas. O modelo de percolação química empregado, no regime pulsante, permitiu o cálculo da evolução dinâmica de CO, CO2, CH4, H2O, outros gases leves e alcatrão, importantes no processo de ignição e estabilização de chamas. O modelo também forneceu a quantidade e forma dos compostos nitrogenados liberados no processo de pirólise que são indispensáveis nas estratégias para abatimento da emissão de poluentes (NOx) em regimes de queima excitados por oscilações acústicas.

The chemical percolation devolatilization model (CPD) was extended for the prediction of drying and devolatilization of coal particles in high intensity acoustic fields found in Rijke tube reactors. The acoustic oscillations enhance the heat and mass transfer processes in the fuel bed as well as in the freeboard, above the grate. The results from simulations in a Rijke tube combustor have shown an increase in the rate of water evaporation and thermal degradation of the particles. The devolatilization model, based on chemical percolation, applied in pulsating regime allowed the dynamic prediction on the yields of CO, CO2, CH4, H2O, other light gases as well as tar which are important on ignition and stabilization of flames. The model predicted the quantity and form of nitrogen containing species generated during devolatilization, for which knowledge is strategically indispensable for reducing pollutant emissions (NOx) in flames under acoustic excitation .

Monthly catches were carried out during five days/month in the Adolpho Ducke Forest Reserve (Manaus, Amazonas), from February 1990 to January 1991 in order to assess the sandfly fauna of that region, evaluate the atractivity of these insects with regard to different kinds of traps and baits and to know vertical stratification of these insects. The traps and baits used in catches were: Disney traps with baits: Didelphis sp., Gallus sp. and Mesocricetus sp.; CDC light traps at three vertical levels (1m, 5m and 10m); Suspended trap (5m) and Malaise trap (1m) and catches on bases of tree-trunks. The most efficient type was the CDC. Malaise and Suspended did not collect specimens of Culicoides Latreille, 1809. The Disney traps with baits only attracted specimens of C. fusipalpis Wirth & Blanton, 1973. In vertical stratification, the CDC trap placed at 1m caught 898 specimens of nine species; at 5m 895 specimens were collected which belonged to 13 species; and at 10m 224 specimens of 14 species were collected. Two thousand and forty-six specimens of Culicoides were captured, being about 5,66% males and 94,34% females, which belonged to 17 different species; the most frequent were C. fusipalpis (43,05%), followed by C. pseudodiabolicus Fox, 1946 (32,79%), C. hylas Macfie, 1940 (12,31%) and C. foxi Ortiz, 1950 (3,71%). The other 13 species totalized 8,15%.
