1. Response of mangrove plant species to a saline gradient: Implications for ecological restoration
ABSTRACT Mangroves are salt tolerant plants that occur in tropical and sub-tropical sheltered coasts. Saltwater intrusions into terrestrial landscapes often occur due to either anthropogenic reasons or natural calamities such as tsunamis. We investigated the potential of using mangrove species for rehabilitation of high saline environments by revealing the c

2. Transmission control of schistosomiasis mansoni in a low endemicity area through a single intervention with rigorous prospection of infected cases treated with praziquantel: evaluation after 7 years of intervention
ABSTRACT A prospective cohort study with rigorous searching for schistosomiasis cases was conducted among residents of Pedra Preta, Montes Claros, Minas Gerais State, Brazil, seven years after an intervention. Kato-Katz (KK), Saline Gradient, Miracidia Hatch and Polymerase Chain Reaction (PCR) were used as the diagnostic methods in 2008. In the period of 201

3. Value of Contrast Transesophageal Echocardiography in the Detection of Intrapulmonary Vascular Dilatations in Hepatosplenic Schistosomiasis
Resumo Fundamento: A síndrome hepatopulmonar (SHP), presente em pacientes cirróticos, é pouco estudada na esquistossomose hepatoesplênica (EHE) e inclui a ocorrência de dilatações vasculares intrapulmonares (DVP). O ecocardiograma transesofágico com contraste (ETEc) de microbolhas é mais sensível que o ecocardiograma transtorácico com contraste (

4. Lipid core nanoparticles resembling low-density lipoprotein and regression of atherosclerotic lesions: effects of particle size
Particles are usually polydispersed and size is an important feature for lipid-based drug delivery systems in order to optimize cell-particle interactions as to pharmacologic action and toxicity. Lipid nanoparticles (LDE) with composition similar to that of low-density lipoprotein carrying paclitaxel were shown to markedly reduce atherosclerosis lesions indu

5. Performance of POC-CCA® in diagnosis of schistosomiasis mansoni in individuals with low parasite burden
Abstract: INTRODUCTION: Schistosomiasis, caused by Schistosoma mansoni, is a public health concern in Brazil. However, the most popular diagnostic method, the Kato-Katz technique, exhibits low sensitivity in low-endemicity areas. We aimed to compare the performance of an immunological assay, the point-of-care circulating cathodic antigen (POC-CCA®) test,

6. A conventional polymerase chain reaction-based method for the diagnosis of human schistosomiasis in stool samples from individuals in a low-endemicity area
The aim of this study was to evaluate the efficacy of a polymerase chain reaction (PCR)-based method to detect Schistosoma mansoni DNA in stool samples from individuals living in a low-endemicity area in Brazil. Of the 125 initial stool samples, 80 were ELISA reactive and eggs were identified in 19 of the samples by parasitological examination. For the PCR e

7. Effects that nutritional and saline gradients have on the growth of Passiflora mucronata Lam. and Canavalia rosea (Sw.) DC. found in the restinga of Brazil
Salinity and fertility are the main factors cited in Within the restinga (coastal woodland) biome in Brazil, the positioning of Canavalia rosea and Passiflora mucronata occur, respectively, near the shore-in the creeping psammophyte formation (CPF) - and far from the shore - in the Palmae formation (PF). The hypothesis that such positioning is related to sal

8. The combination of three faecal parasitological methods to improve the diagnosis of schistosomiasis mansoni in a low endemic setting in the state of Ceará, Brazil
Laboratory diagnosis of intestinal schistosomiasis mansoni can be accomplished through various methods of stool examination to detect parasites, ranging from the most classic tests (Kato-Katz) to several methods that are still undergoing validation. This study was conducted to assess two new parasite identification methods for diagnosing schistosomiasis mans

9. Spatial and temporal structure of fish assemblages in a hyperhaline coastal system: Ría Lagartos, Mexico
The spatial and temporal fish species assemblages were analyzed throughout two annual cycles (2004-2005 and 2007-2008) in the Ría Lagartos Lagoon system, Mexico, via non-parametric multivariate analyses. We compared density and biomass of fish species among five habitat types defined by combinations of structure and environmental characteristics (hyperhalin

10. Sequential voltammetric determination of chromium, thallium, cadmium, lead, copper and antimony in saline hemodialysis concentrates using electrolyte pH gradient
The sequential voltammetric determination of chromium, thallium, cadmium, lead, copper and antimony in dialysate concentrates (DCs), is presented herein. Chromium was quantified by adsorptive cathodic stripping voltammetry and thallium, cadmium, lead, copper and antimony were assayed by anodic stripping voltammetry. The novel method developed to test these s

11. AvaliaÃÃo de trÃs mÃtodos coproscÃpicos para diagnÃstico da esquistossomose mansÃnica em Ãrea de baixa endemicidade no Estado do CearÃ. / Evaluation of three methods for parasitological diagnosis of Schistosoma mansoni in low endemic in the State of CearÃ.
A Esquistossomose MansÃnica à uma doenÃa endÃmica em 76 paÃses e territÃrios. Em meados de 2003, calculou-se que 779 milhÃes de pessoas estavam dentro da populaÃÃo de risco para esquistossomose, e 207 milhÃes de pessoas estavam infectadas. O diagnÃstico laboratorial dessa parasitose pode ser realizado atravÃs de mÃtodos parasitolÃgicos de fezes

12. DETERMINAÇÃO SEQUENCIAL DE CROMO, TÁLIO, CÁDMIO, CHUMBO, COBRE E ANTIMÔNIO EM CONCENTRADO POLIELETROLÍTICO PARA HEMODIÁLISE POR VOLTAMETRIA DE REDISSOLUÇÃO ATRAVÉS DE UM GRADIENTE DE pH / SEQUENTIAL DETERMINATION OF CHROMIUM, THALLIUM, CADMIUM, LEAD, COPPER AND ANTIMONY IN SALINE HEMODIALYSIS CONCENTRATES BY STRIPPING VOLTAMMETRY USING ELECTROLYTE pH GRADIENT
A Determinação sequencial de cromo, tálio, cádmio, chumbo e cobre e antimônio em concentrado polieletrolítico para hemodiálise (CPHD) é descrita. Estes concentrados contêm uma concentração extremamente alta de íons cloreto (cerca de 3,8 mol L-1), o que torna difícil a análise direta por muitas técnicas analíticas. As condições experimentais
