1. Integrated use of sewage sludge and basalt mine waste as soil substitute for environmental restoration
Abstract If not managed properly, mining waste can be detrimental to the environment. In addition, sewage treatment plants produce sludge, a biowaste rich in organic matter which is often sent to landfills. The present study evaluated the use of sewage sludge as an amendment for mine waste from a basalt quarry as an alternative to the use of soil from borrow

2. Storage of boar semen at 16-18 °C in the long-term commercial extender prepared with deionized water or nanowater
Abstract The aim of this study was to assess the usefulness of nanowater (NW; water declusterized using cold plasma treatment) as a diluent for a commercial boar semen extender during the 15-day storage (Days 1 to 15) at 16-18 °C. Ejaculates collected from 8 boars were subjected to the standard evaluation and then diluted in the extender prepared with deion

3. Preparation and application of Zero Valent Iron immobilized in Activated Carbon for removal of hexavalent Chromium from synthetic effluent
RESUMO Diferentemente dos contaminantes orgânicos, os metais pesados não são biodegradáveis e tendem a se acumular nos organismos vivos e também são reconhecidos por serem tóxicos ou carcinogênicos. A utilização de nanopartículas de ferro zero valente (nFVZ) é relatada como uma técnica alternativa e de elevado potencial para remediação in situ

4. CO2 laser and/or fluoride enamel treatment against in situ/ex vivo erosive challenge
ABSTRACT Objective This in situ/ex vivo study investigated the effect of CO2 laser irradiation and acidulated phosphate fluoride gel (APF) application, separately and in combination, on enamel resistance to erosion. Material and Methods During 2 experimental 5-day crossover phases, 8 volunteers wore intraoral appliances containing bovine enamel blocks wh

5. APLICAÇÃO DE ÓXIDOS DE FERRO NANOESTRUTURADOS COMO ADSORVENTES E FOTOCATALISADORES NA REMOÇÃO DE POLUENTES DE ÁGUAS RESIDUAIS
New techniques for treating wastewater, particularly the removal or degradation of organic pollutants and heavy metals, among other pollutants, have been extensively studied. The use of nanostructured iron oxides as adsorbent and photocatalyst for the removal of these contaminants has proved a promising approach, not only because of their high treatment effi

6. Ex-situ bioremediation of Brazilian soil contaminated with plasticizers process wastes
The aim of this research was to evaluate the bioremediation of a soil contaminated with wastes from a plasticizers industry, located in São Paulo, Brazil. A 100-kg soil sample containing alcohols, adipates and phthalates was treated in an aerobic slurry-phase reactor using indigenous and acclimated microorganisms from the sludge of a wastewater treatment pl

7. Biorremediação de solos contaminados com hidrocarbonetos totais de petróleo - enfoque na aplicação do processo terraferm
Contaminações de solos com hidrocarbonetos de petróleo são um problema ambiental com abrangência mundial devido à alta demanda de produtos refinados de petróleo. As fontes são múltiplas e estão relacionadas à exploração, produção, armazenamento, transporte, distribuição e à destinação final de petróleo e seus derivados. Hoje o Brasil est

8. Autotransplante de fígado em Testemunha de Jeová portador de hepatocarcinoma
Hepatocellular carcinoma is one of the most frequent entities worldwide and partial hepatectomy has been the preferred option for treatment. We report the case of a 28-year-old Jehovah's Witness who came to us complaining about an abdominal mass. Angio-MRI showed a large heterogeneous mass in the left hepatic lobe. Ex situ liver resection followed by right h

9. Conservação in situ de Maytenus ilicifolia Mart. ex Reiss. (Celastraceae) na Floresta Nacional de Irati - PR.
The conservation of biodiversity is a priority and strategic question at world level. During the last decades, the intensive extraction of non-timber species resulted in the loose of biological diversity and degradation of natural forests. The recent expansion of medicinal plants, almost exclusively founded on extractivism contributes to degradation of these

10. Biomagnificação do heptacloro num modelo de simulação em condições ex-situ / Biomagnification of heptacloro in a model of simulation in former-situ conditions
The studies carried out in different parts of the world about the pesticides use and the impacts that they can cause to the environment, are one of the priority actions for the agriculture development, mainly for those pesticides that are persistents in the biotic and abiotic environment, such as the heptachlor insecticide, which is still illegally used for

11. The hepatic clearance of recombinant tissue-type plasminogen activator decreases after an inflammatory stimulus
We have shown that tissue-type plasminogen activator (tPA) and plasma kallikrein share a common pathway for liver clearance and that the hepatic clearance rate of plasma kallikrein increases during the acute-phase (AP) response. We now report the clearance of tPA from the circulation and by the isolated, exsanguinated and in situ perfused rat liver during th

12. Isolation of the prohead core of bacteriophage T4 after cross-linking and determination of protein composition.
The naked core of bacteriophage T4 was isolated ex vivo after cross-linking with either glutaraldehyde or dithiobis(succinimidyl propionate). The isolated particles appeared to be morphologically identical to the cores found in thin sections, to those demonstrated in in situ lysis preparations, and to core structures assembled in vitro. Treatment with glutar
