1. McKittrick-Wheelock Syndrome Secondary to Rectal Adenocarcinoma
ABSTRACT Introduction McKittrick-Wheelock syndrome is a rare condition that arises from a hypersecretory state secondary to large colorectal tumors, mainly villous adenomas, leading to an electrolytic disorder associated with chronic diarrhea that usually persists for years. It is a relatively unknown disease that can lead to severe complications such as ac

4. Removal of organic matter from pre-treated domestic sewage in anaerobic biological reactor by a combined system of electrolytic and biological aerobic treatment
Resumo Os processos biológicos são os métodos mais difundidos para o tratamento de águas residuárias. No entanto, eles têm limitações para degradar poluentes tóxicos e refratários, contaminantes, que os processos eletroquímicos podem remover. Portanto, o objetivo da pesquisa foi verificar a possibilidade de tratamento de esgoto por um processo bio

5. Obtaining an Optical Trap Type Surface by Plasma Electrolytic Oxidation
High performance solar collectors are those with high selectivity surfaces, high solar radiation absorption and that do not thermally reemit to the external environment. Strategies to enhance this performance might involve surface porosity modification. In this work, a plasma treatment technique called plasma electrolytic oxidation (PEO) has been tested to p

6. Selective Surfaces of Black Chromium for Use in Solar Absorbers
One of the applications of selective surfaces is to improve performance of solar absorbers. The purpose of this work is to produces selective coatings with high absorption of solar radiation in the range of UV/Vis/NIR. It was prepared a selective surface composed of black chromium (Cr/Cr2O3) deposited on substrates of AISI 304 stainless steel using the techn

7. Tadalafil: Protective Action against the Development of Multiple Organ Failure Syndrome
Abstract Introduction: Multiple organ failure syndrome (MOFS) is a pathology associated to unspecified and severe trauma, characterized by elevated morbidity and mortality. The complex inflammatory MOFS-related reactions generate important ischemia-reperfusion responses in the induction of this syndrome. Nitric oxide elevation, through the activation of cyc

8. VALIDAÇÃO DO PROCESSO DE ELETROCOAGULAÇÃO E AVALIAÇÃO DA ELETRODISSOLUÇÃO DE ELETRODOS NO TRATAMENTO DE EFLUENTES DE ABATEDOUROS DE AVES
The electrocoagulation have been considered a promising technology for wastewater food treatment. This paper evaluates the application of electrocoagulation for the treatment of poultry slaughterhouse wastewater using two types of electrode, iron and aluminum. The initial pH, the electrolysis time and the electrical current density were used as the operating

9. Electrolytic treatment and biosurfactants applied to the conservation of Eugenia uniflora fruit
Abstract Microorganisms are the primary responsible for food poisoning and food spoilage. The purpose of this study was to evaluate different fruit washing methods with tap water, electrolyzed water and rhamnolipids solution produced by Pseudomonas aeruginosa LBI, in order to inhibit microbial growth. The tested organism was Eugenia uniflora. The fruits were

10. Augmentation of wear-protective coatings for non-ferrous alloys by the addition of Cr and Ni elements
A number of Al-, Mg- and Ti-base alloys were preconditioned by oxidation via Plasma-electrolytic oxidation (PEO) followed by the addition of Cr and Ni elements in the coating pores by chemical precipitation and a final stage of mechanical treatment. The overall effect was a combination of hardness and resistance to wear. PEO voltage level was found to be a f

11. Cloning of Ammopiptanthus mongolicus C-repeat-binding factor gene and its cold-induced tolerance in transgenic tobacco
C-repeat-binding factors (CBFs) are a type of important regulon in stress-related signal transduction pathways that control plant tolerance of abiotic stress. Ammopiptanthus mongolicus is the only evergreen broadleaf shrub in the northwest desert of China. The species shows strong resistance to environmental stress, especially to cold stress. An A. mongolicu

12. Photo-assisted electrochemical copper removal from cyanide solutions using porous TiO2 thin film photo-anodes
TiO2 porous films were prepared on ITO coated glass slides by the sol-gel dip-coating method assisted with Polyethylene glycol (PEG). The films were used as photo-anodes in the photo-assisted electrolytic removal of cuprous ions in cyanide media. These were characterized by SEM, UV-Visible spectroscopy and XRD. The PEG modified films were free of cracks and
