ABSTRACT

In the present study, metagenomic technique and fosmid vectors were used to construct a library of clones for exploring the biotechnological potential of mangrove soils by isolation of functional genes encoding hydrolytic enzymes. The library was built with genomic DNA from the soil samples of mangrove sediments and the functional screening of 1824 clones (~64 Mbp) was performed to detect the hydrolytic activity specific for cellulases, amylases (at acidic, neutral and basic pH), lipases/esterases, proteases, and nitrilases. Significant numbers of clones, positive for the tested enzyme activities were obtained. Our results indicate the importance and biotechnological potential of mangrove soils especially when compared to those obtained using other soil metagenomic libraries.

ABSTRACT

We investigated the biodegradability of oil in mangrove sediment from Camamu Bay and measured its effect on the bacterial community. Microcosms of mangrove sediment were contaminated with 0.1, 0.5, 1, 2, and 5% (w/v) oil, and the microbial activity was compared to that in uncontaminated sediment. The evolution of CO2 and gas chromatography showed the mineralization of oil compounds, which could reach 100%. Bacterial diversity was determined by polymerase chain reaction using a set of primers for the V3 and V6-V8 regions of 16S rDNA. The band profile obtained by denaturing gradient gel electrophoresis of the amplicons that were obtained for the V3 region showed a negative correlation between band number and oil concentration, whereas that of the V6-V8 region showed a positive correlation between band numbers and oil concentration. The latter also gave similar results for microcosms that were contaminated with 2 and 5% oil. These results demonstrate the mangrove sediment's capacity to recover from oil contamination (in vitro) and suggest that native mangrove microorganisms contain enzymes necessary for the catabolism of oil.

ABSTRACT

O leite é um alimento de elevado valor nutricional e considerado um dos principais produtos de origem animal consumidos nos dias de hoje. O Brasil destaca-se como um dos principais produtores de leite do mundo e desde 2006 vem apresentando aumento crescente em sua produção. Por outro lado, também se observa desde o início da década de 1990, crescimento do chamado leite e produtos lácteos informais (alimentos comercializados sem qualquer tipo de inspeção), representando desafio a ser vencido com relação à segurança alimentar. Muitas são as enfermidades que podem ser transmitidas por esses alimentos, como por exemplo, a tuberculose e a brucelose e poucos são os consumidores que estão atentos a essas informações. O fato agrava-se ao pensar que o leite e os produtos lácteos compõem a dieta de muitas crianças, idosos e pessoas imunocomprometidas, o que pode tornar esse quadro mais grave. O presente trabalho teve como objetivo avaliar, por meio da aplicação de questionários em 23 bairros do município de São José do Rio Preto, o perfil de 805 entrevistados, que consomem ou não leite e produtos lácteos, o conhecimento que os mesmos apresentavam sobre as doenças transmitidas pelo leite e seus derivados e o significado dos selos dos Serviços de Inspeção. Como resultado, observou-se que 97,76% (787/805) dos entrevistados consomem leite ou seus derivados, e aproximadamente 30% são obtidos por meios informais de comércio. A forma de consumo desse produto é bastante variável, mas 3,93% (31/787) dos consumidores do município ainda ingerem leite cru sem a fervura ou pasteurização e 65,96% (531/805) dos consumidores desconhecem a possível transmissão de doenças através da ingestão do leite. Além disso, 80,24% (646/805) dos consumidores não procuram nas embalagens se o produto passou por algum tipo de fiscalização antes de chegar ao comércio - identificação através dos selos dos órgãos de inspeção sanitária. A obtenção desses dados visou...(AU)


Milk is a food of high nutritional value and is considered one of the main animal products consumed today. At the same time, Brazil stands out as one of the leading milk producers in the world and, since 2006 has been showing growing increase in its production. On the other hand, it is observed from the beginning of the 1990s, the growth of so-called informal milk and milk products (foods marketed without any kind of inspection), representing a challenge to be overcome related to food security. There are many diseases that can be transmitted by such foods, as tuberculosis and brucellosis, and there are few consumers who are aware of such information. The fact worsens the thought that milk and dairy products make up the diet of many children, elderly and weakened persons, which may make it more severe. Thus, this study aims to evaluate, through the use of questionnaires in 23 districts of São José do Rio Preto, the profile of 805 consumers or not, of milk and dairy products, the knowledge that they have about the diseases transmitted by milk and dairy products and the significance of the seals from Inspection Services. As a result, it was found that 97.76% (787/805) respondents consume milk or its derivatives, and about 30% are obtained by informal means of commerce. The form of consumption of this product is quite variable, but the work shows that 3.93% (31/787) of the consumers still ingest raw milk without boiling or pasteurization and 65.96% (531/805) of consumers are unaware of the possible transmission of disease by the ingestion of milk. Furthermore 80.24% (646/805) of consumers do not seek the packaging if the product has gone through some kind of supervision before reaching the trade - identification through stamps organs of sanitary inspection. Obtaining such data aims to collaborate in future for the development of prevent programs in the city, and the information...(AU)

ABSTRACT

Solutions to induce or suppress the initiation of sperm motility in fish ha ve been used to improve reproductive success during artificial fertilization and preservation techniques . The aim of the present study was to evaluate the effects of three solutions (NaCl, glucose , and BTS™) - each prepared with 10 different osmolalities - on the initiation and suppression of fresh sperm motility in Prochilodus lineat us and Brycon orbignyanus . Sperm was diluted in each of the 30 solution s and immediately observed under a light microscope to determine which solution s trigger ed or suppress ed the initiation of sperm motility. When present, motility rate ( % motile sperm ) w as determined at 0, 30 , and 120 s post - activation and the motility quality score ranging from 0 ( no movement ) to 5 ( rapidly swimming sperm) was determined at 0 and 30 s post - activation . Osmolality , but not solution composition , significantly affected both motility rate and quality score . Solutions at osmolali ties up to 270 mOsm/kg in P. lineatus and up to 180 mOsm/kg in B. orbignyanus induced motility in at least 60% of sperm , with a minimum quality score of 3.0 , and were therefore classified as activating agents. The greatest motility at 0 , 30 , and 120 s post - activation was observed with solutions ranging from 135 to 225 mOsm/kg for P. lineatus and at 135 mOsm/kg for B. orbignyanus . On the other hand, solutions ranging from 360 to 450 mOsm/kg in P. lineatus and 270 to 450 mOsm/kg in B. orbignyanus suppressed motility in at least 95% of sperm and were classified as immobilizing media . The osmolality of the surrounding medium is the key factor in the initiation or suppression of sperm motility in P. lineatus a nd B. orbignyanu.(AU)

ABSTRACT

Studies regarding the effects of extender composition, osmolality, cryoprotectant (CPA) and equilibration time on the induction/suppression of sperm motility are necessary to establish standard activating agents and immobilizing media for improving both artificial fertilization and pr eservation techniques. Thus, the aim of this study was to evaluate the effects of these factors on fresh sperm motility in piracanjuba ( Brycon orbignyanus ) and streaked prochilod ( Prochilodus lineatus ). Twenty four media, as a combination of six extenders (BTS™ and glucose solutions at 270, 315 and 360 mOsm/kg) with the CPAs DMSO, methanol, methyl glycol (MG) and a control without CPA, were prepared. Immediately after dilution, samples were observed under a light microscope to confirm whether different extender-CPA combinations would suppress the initiation of sperm motility. Motility was then triggered in 92 mOsm/kg NaCl and evaluated immediately after dilution (non-equilibrated samples) and after a 30-min equilibration time at 4°C for motility rate and motility quality score (0 = no movement; 5 = rapidly swimming sperm). In both species, motility was initiated in all samples diluted in BTS-270-control, Glu-270-MG, Glu- 270-control and in all combinations containing DMSO. In B. orbignyanus , motility rate (77 to 92%) and motility quality score (3.3 to 4.7) of non-equilitrated samples was not significantly affected by any parameter. After 30 min, however, motility quality score decreased in most of the samples, mainly when diluted in BTS™ (3.3 to 4.2). In P. lineatus , motility rate was significantly higher in non-equilibrated samples (overall mean = 83%) compared to 30-min equilibrated samples (overall mean = 75%). Motility quality score of non- equilibrated samples was not affected by any parameter (3.3 to 4.2), but samples equilibrated in DMSO yielded the lowest score (3.0). Sperm motility (rate and score) was affected differently in B. orbignyanus compared to P. lineatus , and this finding should be considered when developing a methodology for sperm cryopreservation.(AU)

ABSTRACT

A farmacoterapia pediátrica exige uma variedade de formas farmacêuticas adequadas às diferentes fases do desenvolvimento da criança. O objetivo deste estudo foi identificar os antimicrobianos utilizados em dois hospitais e verificar se realmente havia adequação das formas farmacêuticas aos pacientes pediátricos. Os antimicrobianos foram identificados pelo sistema informatizado das farmácias. Os medicamentos foram analisados, levando-se em consideração a necessidade de transformação da forma farmacêutica, o fracionamento e a porcentagem de desperdício. Verificou-se que 97,2% dos medicamentos analisados foram considerados inadequados para utilização em recém-nascido prematuro; 82,5% foram considerados inadequados para uso em recém-nascido a termo e 68,1% foram considerados inadequados para lactentes. A falta de formulações adequadas para essas faixas etárias acarreta frequentes manipulações, o que pode comprometer o uso adequado dos medicamentos, principalmente dos medicamentos parenterais. Identificou-se, também, a necessidade de transformação dos medicamentos sólidos de uso oral. Essas atividades, sem dúvida, elevam o risco de contaminação e/ou de inexatidão da dose. Os resultados mostram uma falta de formulações farmacêuticas de antimicrobianos adequadas para utilização nas diversas faixas etárias pediátricas, sendo, portanto, necessárias ações das autoridades sanitárias para assegurar a disponibilidade de formulações apropriadas, contribuindo para a promoção do uso racional de medicamentos em pediatria.


Pediatric pharmacotherapy requires a variety of drug dosage forms suited to different stages of child development. The aim of this study was to identify the antimicrobial drugs used in the pediatric units of two hospitals and to examine whether the drug dosage forms used were really suitable for pediatric patients. The antimicrobial drugs were identified through the computerized system of the hospital dispensaries. The medicines were analyzed regarding the need to transform or split the drug dosage form and the amount wasted. A total of 92.7% of the medicines analyzed were inappropriate for use with a preterm neonate, 82.5% were unsuitable for a term neonate and 68.1% were unsuitable for infants. The lack of suitable formulations for these age groups may lead to more frequent compounding of drugs, hampering the correct use of medicines, especially parenteral drugs. A need to transform solid oral drug forms was identified. Such activities certainly increase the risk of drug contamination or inaccuracy of dose. The results showed a lack of pharmaceutical formulations of antimicrobial drugs suitable to be given to various pediatric age groups. Therefore, health authorities should ensure the availability of appropriate drug dosage forms for children, in order to promote the rational use of drugs in pediatrics.
