Increased attention has been paid to the synthesis of hematite nanoparticles recently due its properties and application in various fields modern technology. The aqueous route found be simpler more versatile than non-aqueous routes. In this study nanopowder a-Fe2O3 (hematite) were synthesized by controlled precipitation method three stages: precursors, washing calcination. was with ferric chloride as precursor, sodium hydroxide precipitant, constant agitation pH 6. It tested different...

This study used substituted barium hexaferrites, which were previously prepared and reported by the authors, to detect acetaminophen modification of a conventional glassy carbon electrode (GCE), led promising results. The synthesis this electrode-modifying material was conducted using citrate sol gel process. A test glycerin propylene glycol revealed that produced better result, while less positive anodic potential values associated with electrooxidation N-acetyl-p-aminophenol (NAP)....
Taenia solium cysticercosis is a parasitic disease frequently affecting human health and the pig industry in many developing countries. A synthetic peptide vaccine (designated S3Pvac) against porcine has been developed previously as an aid to interrupt transmission shown be effective. The results of present study support effectiveness under endemic field conditions. However, given time-frame vaccination trial, no changes local levels were detectable before after using sentinel pigs. Thus,...
If a programme for the control of pig cysticercosis is to be effective it has based on good data local epidemiology Taenia solium. In 2002-2003, in cross-sectional study Mexican state Morelos, 1747 pigs that had been born and reared rural areas were checked T. solium infection by tongue inspection. The prevalence was found vary from 0% 30% according municipality which came. Although appeared unaffected socio-economic status municipality, relatively high lacked latrines, castrated, pregnant...
Environmental context Sorption and oxidation reactions at mineral surfaces can substantially influence the mobility toxicity of environmental contaminants. An understanding factors that control these is crucial for predicting fate contaminant species. We investigate reactivity manganese oxides towards polycyclic aromatic hydrocarbons, persistent organic compounds concern. Abstract Birnessites are ubiquitous components natural systems may exert a significant on different types contaminants,...
Summary Objective To describe and compare the clinical impacts of neurocysticercosis (NC) caused by Taenia solium in humans pigs. Methods Comparative study brains 16 asymptomatic pigs 35 human NC cases (15 20 symptomatic). Results In humans, cysticerci were more frequently located ventricles subarachnoid space at base brain (11.8% vs. 1.6%; P = 0.001 25.9% 0%; < 0.0001, respectively) while pigs, found parenchyma (44.4% 7.6%; 0.0001). brains, 75.9% calcified, all vesicular stage....
This work devised a simple glycerol-assisted synthesis of low-Cu2+-doped CoFe2O4 and the electrochemical detection acetaminophen (AC). During synthesis, several polyalcohols were tested, indicating efficiency glycerin as cosolvent, aiding in creation electrode-modifier nanomaterials. A duration standing time (eight hours) before calcination produces decrease secondary phase hematite. The synthesized material was used an electrode AC. In acidic conditions (pH 2.5), limit (LOD) 99.4 nM, while...
This work presents, for the first time, power generation using diabetic urine as fuel. The energy conversion is achieved through a paper-based microfluidic fuel cell. Urine has recently gained attention source of novel biomarkers early disease detection, making use particularly relevant to development autonomous portable medical devices. A key challenge in lies fact that it contains various molecules and compounds can block or poison cell's electrodes. study introduces selective catalyst ZnO...
A voltammetric and spectroelectrochemical ESR study of the reduction processes five substituted 4-R-2-nitrophenols (R = −H, −OCH3, −CH3, −CN, −CF3) in acetonitrile was performed. In potential range considered here (−0.2 to −2.5 V vs Fc+/Fc), two signals (Ic IIc) were detected; first one associated with formation corresponding hydroxylamine via a self-protonation pathway. The analysis at signal showed that there are differences pathway for each 4-R-2-nitrophenol, being E1/2 values determined...
The disease caused by Taenia solium is progressively being recognized as a growing global threat for public human health and pig husbandry that requires the development of effective control measures. A central participant in taeniasis/cysticercosis transmission network carrier adult tapeworm because its great potential spreading infection. Herein, evidence presented primary infection golden hamsters with orally administered T. cysticerci improved host's resistance against secondary Likewise,...
Abstract In the present work we report synthesis of mixed ferrites doped with Co 2+ , Cu and Ba cations, using citrate sol–gel combustion route in air atmosphere, at 950 °C for 3 hours, produced substituted M-type barium powders particles crystallite sizes varying between 145 155 nm. The percentages yield obtained were on average 42%. synthesized characterized by techniques such as powder X-ray diffraction, evidencing formation hexaferrite copper cobalt ferrite hematite smaller proportion....
