ACIDITY OF HUMIC ACIDS.The acidity determinations method of humic acids (HA) content was developed by Schnitzer and Gupta and is a very well known procedure.Nevertheless, care is necessary to prevent measure errors due to non-controlled BaCO 3 production, during the filtration and titration of HA total acidity.To overcome this problem, we developed in our laboratory a simple filtration and titration system for the determination of HA acidity under inert atmosphere.This system enables a better reproducibility ...

The objective of this study was to determine the prevalence of parasites in soil and dog feces according to diagnostic tests. We studied soil from 25 public squares in Seropédica, Brazil. Five samples of soil were collected from each square. Eighty-one fresh fecal samples from dogs were analyzed. The technique described by Dunsmore et al. and an adaptation of the Rugai et al. method were used to recover parasites in soil, and the Willis, Hoffman and Centrifugal-Flotation techniques were used to ...

Osteoarthritis (OA) is a common chronic disease for which disease-modifying therapies are not currently available. Studies to seek new targets for slowing the progress of OA rely on mouse models, but these do not allow for longitudinal monitoring of disease development. This study was undertaken to determine whether gait can be used to measure disease severity in the STR/Ort mouse model of spontaneous OA and whether gait changes are related to OA joint pain.Gait was monitored using a treadmill-based ...

Immunofluorescence tests (IF) for toxoplasmosis were performed on a total of 608 schoolchildren in elementary and junior high grades. 166 being in the Bonsucesso district (an urban region of Rio de Janeiro) and 442 children from locations within the lowlands of Jacarepaguá (with rural characteristics). All the IF-IgM were nonreactive, whilst 416 schoolchildren (68.4%) were IF-IgG serum-reactive (greater than or equal to 1:16). The percentages of serum-reactives in Jacarepaguá were significantly higher ...

Crude extracts from the aerial parts of Lychnophora granmongolense (Asteraceae) were bioassayed for trypanocidal (trypomastigote forms of Trypanosoma cruzi) and analgesic (writhing test) activities. The crude ethyl acetate extract from the leaves plus inflorescences exhibited trypanocidal activity but no analgesic activity in the writhing model of pain. The bioassay-guided fractionation of this extract yielded three trypanocidal compounds: the sesquiterpene lactones centratherin (lychnophorolide A) ...

São Paulo is the most economically developed state of Brazil, and its coast is protected by a system of MPAs, including the North Shore Marine Protected Area (NSMPA). The present study provides a first assessment of sediment quality in NSMPA and two reference sites. Concentrations of arsenic (As), metals (Al, Fe, Cd, Cr, Cu, Ni, Pb, and Zn) and polycyclic aromatic ...

Margarine contains a considerable amount of sodium and is used on breads and crackers. In this context, the objective of the present study was to evaluate the market appeal and effects of adding spices to margarine in terms of reducing the sodium content and increasing antioxidant activity. A questionnaire assessing market appeal was developed along with 12 margarine formulations. The treatment varied in terms of reduced sodium levels (from 100% to 0% reduction) and the addition of two different ...

Polymeric sponge replication technique has been widely used to obtain ceramic foams with a cellular structure for filtration applications. This process is based on an impregnation of a polymeric sponge with ceramic slurry. Ceramic filters must present simultaneously high permeability and strength. However, these parameters are influenced in different ways by the processing method and these properties are inversely proportional. In this work the mechanical properties by compression and flexural has ...

Background HNA ‐3 antigens are the result of a rs2288904 single‐nucleotide polymorphism ( SNP ) in the CTL 2, and the HNA ‐3a and HNA ‐3b variants are encoded by a guanine and adenine at Nucleotide Position 461. Anti‐ HNA ‐3 are involved in severe transfusion‐related acute lung injury reactions and in neonatal alloimmune neutropenia. Since the distribution of the HNA ‐3 system was unknown in S outh A mericans, in this study we determined the frequency of the HNA ‐3 alleles in B razilians. Study Design and ...

The Amazon region has suffered considerable deforestation rates related to logging, cattle ranching, and agriculture. Recently, attention has been given to deforestation due to mining activities. This paper aims to estimate the land area affected by mining activities in protected and nonprotected areas, the value of the traded mineral extraction per commodity, and the mineral commodity with the highest trade (mineral extraction per mining area). Our results show that mining activities occupied 1, ...

The classic abdominoplasty still provides the best aesthetic results, despite many advances in abdominoplasty techniques. However, this procedure is associated with a relatively high incidence of complications. A new technique is described that combines lipoplasty with traditional abdominoplasty without undermining of the abdominal flap. Lipoplasty proceeds from the region above the umbilicus to the flanks and the region below the umbilicus. The skin below the umbilical scar is resected as in classical ...

Intermediate-length cytosine-adenine-guanine nucleotide repeat expansions in the ATXN2 gene (which encodes for the protein Ataxin-2) have been linked to increased risk for amyotrophic lateral sclerosis (ALS) in different populations. There is no such study in the Brazilian population, which has a mixed ethnic background. We have thus selected 459 patients with ALS (372 Sporadic ALS and 87 Familial ALS) and 468 control subjects from 6 Brazilian centers to investigate this point. We performed polymerase ...

Strains of Toxoplasma gondii in Brazil are highly genetically diverse compared to strains from North America and Europe. Dogs are epidemiologically important because they act as sentinels for T. gondii infections in humans and are good indicators of environmental contamination. The aim of this study was to isolate and genetically characterize T. gondii strains from tissues of naturally infected Brazilian dogs. For this study, 21 blood samples were collected from dogs at the Zoonosis Control Centers ...

Abstract We studied 2351 participants with coronavirus disease 2019; 1177 (50%) reported previous dengue infection. Those without previous dengue had a higher risk of death (hazard ratio: .44; 95% confidence interval: .22–.89; P = .023) in 60-day follow-up. These findings raise the possibility that dengue might induce immunological protection against severe acute respiratory syndrome coronavirus 2.

Cassava wastewater (CW) is a residue from the production of flour which contains starch, a biopolymer, in its composition. This paper mainly highlights the use of this effluent in Compressed Stabilized Earth Brick (CSEB) instead of potable water. Compressive strength, water absorption, durability by wetting-drying cycles, X-ray diffraction, and scanning electron microscopy tests were performed to evaluate the mechanical and durability properties of the CSEBs. Compositions with CW showed higher mean ...
