1. Lipoprotein apheresis efficacy and challenges: single center experience
Abstract Introduction Lipoprotein apheresis (LA) is an extracorporeal therapy which removes apolipoprotein B-containing particles from the circulation. We evaluated techniques and efficiency of lipoprotein apheresis procedures applied to patients with familial and non-familial hypercholesterolemia (FH) at our center. Methods We retrospectively evaluated 25

2. Dupla FiltraÃÃo Utilizando Filtro de PressÃo à Montante de Filtro Ascendente em Manaciais Eutrofizados / Double Filtration Using Pressure Filter Upstream Of The Rising Filter In Eutrophic Body Os Water
O processo de tratamento por filtraÃÃo direta costuma ser selecionado para o tratamento de Ãgua com qualidade razoÃvel (baixos a mÃdios teores de cor, turbidez e algas). Nesse processo, as mudanÃas de qualidade - particularmente no que tange à proliferaÃÃo de algas - provocam problemas de sobrecarga nos filtros, uma vez que toda fraÃÃo particulada

3. Avaliação de parâmetros da fermentação e da destilação para adequação dos teores de compostos secundários em aguardente de banana
This study aimed to evaluate the conditions of fermentation and distillation in banana spirit production, aiming at the adequacy of secondary compounds in relation to legislation. The four yeast strains`s fermentative potential was evaluated in banana juice. It also evaluated the steps in the production process: enzymatic hydrolysis, filtration and agitation

4. Tratamento de água para consumo humano de reservatório eutrofizado através de pré e interoxidação, adsorção em carvão ativado e dupla filtração / Drinking water treatment of eutrophic reservoir by pre and interoxidation, activated carbon adsorption and double filtration
Disordered basins occupation provoked acceleration of eutrophication, which besides purely aesthetic and landscaping problems, results in occurrence of high phytoplankton densities with potentially toxic cyanobacteria dominance. Alongside physical aging and consequent deterioration of installations, usual treatment technologies do not provide adequate condit

5. Antibody response following Hepatitis B vaccination in peritoneal dialysis patients: does normalized urea clearance matter?
OBJECTIVES: Data on the factors that contribute to the antibody response to hepatitis B virus vaccination in peritoneal dialysis patients are scarce. The current study was conducted on a group of peritoneal dialysis patients to learn how the response to hepatitis B virus vaccination varies according to the patient's clearance of urea normalized to total body

6. Functional changes of dendritic cells in hypersensivity reactions to amoxicillin
A better understanding of dendritic cell (DC) involvement in responses to haptenic drugs is needed, because it represents a possible approach to the development of an in vitro test, which could identify patients prone to drug allergies. There are two main DC subsets: plasmacytoid DC (pDC) and myeloid DC (mDC). β-lactams form hapten-carrier conjugates and ma

7. Uso crônico de baixas doses de Furosemida em pacientes renais crônicos, com função renal residual submetidos à hemodiálise
Background: The use of diuretics has been proven effective in patients with chronic renal failure by increasing the volume and urinary sodium excretion, but most studies have been performed using high doses of this drug, acutely. The objective of the present study was to verify whether chronic renal patients on HD with residual diuresis who were using small

8. Remoção de oocistos de Cryptosporidium parvum E de indicadores no tratamento de água por ciclo completo, filtração direta descendente e dupla filtração, em escala piloto
Removal of oocysts in drinking water has on granular bed filtration, with previous coagulation and with or without sedimentation an efficient barrier for Cryptosporidium control. USA regulation for Cryptosporidium control in drinking water awards 3,0 log removal to conventional treatment and 2,5 log to direct filtration. In this pilot scale study, convention

9. Carotenoides e compostos bioativos : relação com propriedades anti-radical livre e corante em frutas tropicais / Carotenoids and bioactive compounds : relationship between free radical scavenger properties and color in tropical fruits
The increased demand for high life quality has been associated to healthy food, increasing the industry interest for functional foods, which are defined as any food or bioactive compounds with potential to be benefic for the consumer health. The bioactive compounds found in foods, such as carotenoids, phenolic compounds and ascorbic acid (AA) are involved wi

10. Caracterização da DNase da peçonha da serpente Bothrops alternatus : comparação com a DNase acida de mamiferos envolvida em apoptose / Characterization of a Dnase from Bothrops alternatus snake venom : comparision with mamalian acid Dnases involved in apoptosis
Bothrops snake venoms are cytotoxic to a variety of cells (endothelial, smooth muscle, renal and inflammatory cells), and may cause cell death by apoptosis. The venom components implicated in apoptosis include metalloproteinases and L-amino acid oxidase. In contrast, although acidic deoxyribonucleases (DNase II) have been implicated in DNA fragmentation duri

12. Insuficiência renal aguda relacionada à correção de aneurisma da aorta: análise retrospectiva dos fatores de risco e estudo prospectivo para sua prevenção / Acute kidney injury in aortic surgery: retrospective analysis of risk factors and prospective study for its prevention
Small alterations of the renal function during hospital stay and more specifically in the postoperative period determine significant increase in hospital mortality. In order to determine the incidence of AKI (acute kidney injury) and the risk factors for its development in the postoperative period of elective surgical open repair of thoracoabdominal and abdo
