Abstract: The consumption of beverages and processed foods, mainly soft drinks, has been incorporated into the usual diet of children, adolescents and adults frequently in recent years. The present study aimed to study the effects of carbonated drinks on Wistar rats, based on the macroscopic and histological morphology of the esophagus. Fifteen Wistar rats were divided into three groups: control group; group fed with ration and cola-type refrigerant ad libitum and group fed with ration and gas industrialized water ad libitum, for a trial period of 90 days. For histopathology and morphology, the esophagus was removed, prepared in slides and stained with hematoxylineosin. Images of the sections were captured for analysis and classification of the inflammatory infiltrate. For morphometry, ten grid fields of 100 points were evaluated in the 40x eyepiece, totaling 3000 points per animal. The results demonstrate that the refrigerant treatment induced the following structural changes in the rats: significant reduction of weight in relation to the control group; inflammatory infiltrate predominantly diffuse mild to moderate and tissue edema. The rats treated with carbonated water had similar results to the control, besides signs of healing and tissue repair.

Abstract: The cotton plant is a plant belonging to the family Malvaceae and its leaves are often used in folk medicine. The present study aimed to evaluate the mutagenic or antimutagenic activity of the ethanolic extract of Gossypium barbadense L. (EEG) and to analyze its capacity to prevent or repair mutagenic lesions caused by cyclophosphamide (CP). For the Micronucleus test, Swiss mice were divided into 5 groups: negative control; Positive control: treated with 50 mg/kg cyclophosphamide (CP), group receiving EEG 500 mg/kg for 7 days; Group receiving EEG 500 mg/kg for 7 days associated with CP24h before euthanasia; Group who received CP and EEG 500 mg/kg for 7 days. After the treatment period, the animals were euthanized, the bone marrow removed and the blood smear prepared. From this analysis, it was observed that the EEG caused a significant increase in the number of micronucleated erythrocytes, indicating mutagenic activity of the extract. In addition, it was verified that the extract did not present the capacity to prevent, but it presented the capacity of repair of the chromosomal damages caused by CP.

Abstract: vascular epiphytes are frequent in mesic habitats and mid-elevation regions. the present study investigated the diversity and species composition of epiphytic bromeliads in the natural reserve of serra do teimoso (rnst) located in a transitional area between ombrophilous and semideciduous forests. adapted from the "rapid and representative sampling of vascular and non-vascular epiphyte diversity of tropical rain forests" protocol, our survey method used eight phorophytes of cariniana legalis (martius) kuntze found between 284 and 573 m a.s.l.. we registered 19 morphospecies and 526 bromeliad groups. almost one third of the species were classified as widely distributed and 27.3% are endemic to southern bahia. shannon index was 2.2 nats.ind-1 and the estimated number of species in this area was 25 (sd = ± 3.5). most c. legalis harbored a similar abundance and species composition of epiphytes, which was dominated by hohenbergia and aechmea species. this study registered the occurrence of three species that are new to the state of bahia, and one genus was collected for the first time in the rnst. results are in accordance with the known pattern of lower epiphytic diversity in drier locations. since all new records are exclusive to the crowns of large trees, the sampling of these new records was only possible because climbing techniques were used. compared to other methodologies for floristic surveys, the one employed here demanded lower sample effort and yielded similar results. large trees play an important role for epiphytes due to the concentration of species and individuals on them. thus, the utilization of canopy methodologies in other field surveys would be desirable to sample appropriately epiphytes in large trees.

Abstract: For sugar cane bagasse, the highest glucose yield (86.6% of theoretical) was obtained after pretreatment at 205°C for 15 min. For sugar cane leaves the highest glucose yield (97.2% of theoretical) was obtained after pretreatment at 220°C for 5 min. The reference pretreatment, using impregnation with SO2 and performed at 190°C for 5 min, resulted in an overall glucose yield of 79.7% and 91.9% for bagasse and leaves, respectively.Comparable pretreatment performance was obtained with CO2 as compared to when SO2 is used, although higher temperature and pressure were needed. The results are encouraging as some characteristics of CO2 are very attractive, such as high availability, low cost, low toxicity, low corrosivity and low occupational risk.Approximately 46% of the domestic supply of energy in Brazil is based on renewable energy, with 31% associated with the utilisation of biomass; 15.9% of the energy based on biomass is directly associated with sugar cane and its derivatives [1]. These figures are quite high when compared with those from the world energy matrix, where only 12.9% is associated with renewable energy. An even smaller ratio (6.7%) is observed when examining Organisation for Economic Co-operation and Development (OECD) countries [1].Although Brazilian first-generation ethanol derived from sugar cane's sucrose is the only globally competitive biofuel (US$ 35 per barrel) [2], the production of second-generation ethanol from sugar lignocelluloses (for example, cane bagasse and leaves) is still a technological challenge. The utilisation of bagasse presents the additional advantage of being already available at the factory after processing for the extraction of the sugar cane juice. In the case of leaves, the Brazilian government is becoming more restrictive regarding the burning of residue in the field [3] and the development of more efficient burners [4-6] will also allow more efficient use of this resource. Even though both materials can be used in cogener

Abstract: the main objective of this paper was the quantitative evaluation of the ethanol's influence about the volatilization of btex (benzene, toluene, ethylbenzene and xylenes) in a mixture of gasoline and anhydrous ethanol 25% (v/v) in experimental columns that simulated soil contamination with gasoline/ethanol. all the btex presented expressive increase of volatilization rates in the gasoline-ethanol column. however, in terms of percentage, the highest and lowest volatilization grades were observed for toluene and benzene, respectively. in batch tests (control samples), with mixtures of gasoline ethanol with 0 and 25% (v/v) in ethanol, no increase of the volatilization grade was observed for ethylbenzene and the volatilization grade for xylenes was reduced. matrix effects seem to be, besides the intermolecular interaction forces, important contributions for the volatilization grade of btex in this kind of sample.

Abstract: OBJETIVO: Determinar a prevalência do uso pesado de drogas por estudantes de primeiro e segundo graus em uma amostra de escolas públicas e particulares, e identificar fatores demográficos, psicológicos e socioculturais associados. MéTODOS: Trata-se de um estudo transversal com uma técnica de amostragem do tipo intencional comparando-se escolas públicas de áreas periféricas e centrais e escolas particulares. Foi utilizado um questionário an nimo de autopreenchimento. A amostra foi constituída por 2.287 estudantes de primeiro e segundo graus da cidade de Campinas, SP, no ano de 1998. Considerou-se uso pesado, o uso de drogas em 20 dias ou mais nos 30 dias que antecederam a pesquisa. Para análise estatística, utilizou-se a análise de regress o logística polit mica - modelo logito, visando identificar fatores que influenciem este modo de usar drogas. RESULTADOS: O uso pesado de drogas lícitas e ilícitas foi de: álcool (11,9%), tabaco (11,7%), maconha (4,4%), solventes (1,8%), cocaína (1,4%), medicamentos (1,1%), ecstasy (0,7%). O uso pesado foi maior entre os estudantes da escola pública central, do período noturno, que trabalhavam, pertencentes aos níveis socioecon micos A e B, e cuja educa o religiosa na infancia foi pouco intensa. CONCLUS ES: Maior disponibilidade de dinheiro e padr es específicos de socializa o foram identificados como fatores associados ao uso pesado de drogas em estudantes.
