The growing concern with the amount of plastic materials found in the oceans makes it necessary to develop biodegradable materials that have low toxicity to marine animals and humans, but at the same time are resistant to the actions of microorganisms such as fungi or bacteria. On the other hand, agricultural waste rich in inorganic materials (such as silica) is often discarded, while it could be reused as a source of raw material. Considering these points, sodium silicate solution extracted from ...

Neospora caninum is an apicomplexan parasite responsible for major economic losses due to abortions in cattle. Innate immune responses are crucial for host resistance against the infection, however the molecules involved in parasite recognition are still poorly understood. Nod2 is a cytosolic receptor that recognizes several pathogens and its role during N. caninum infection has not yet been described. In that sense, we evaluated the role of Nod2 in host response against this parasite. We found ...

Visceral leishmaniasis (VL) is a zoonosis caused by the protozoan Leishmania infantum and in Brazil is transmitted mainly by the bite of Lutzomuyia longipalpis sand flies. Data about the presence, distribution, natural infection rate, seasonal and monthly dynamics of the vector population are important for optimizing the measures to control VL in endemic areas. This study aimed to identify sand fly fauna in an endemic area for VL to detect the prevalence of L. infantum infection in the Lu. longipalpis ...

Dificilmente alguém sabe ou imagina que os cemitérios possam causar grandes impactos ambientais e danos à saúde pública. A decomposição da matéria orgânica gera um líquido viscoso, de cor acinzentada-acastanhada e com odor acre e fétido, o necrochorume. Portanto, os cemitérios são depósitos de cadáveres humanos que necessitam de uma destinação correta, pois a degradação dos mesmos pode constituir inúmeros focos de contaminação. Através de uma revisão bibliográfica objetivou-se levantar dados sobre ...

A atenção à saúde é permanentemente desafiada pelas infecções relacionadas aos procedimentos assistenciais, que resultam no aumento da morbidade, mortalidade e custos operacionais. O álcool etílico possui propriedades antimicrobianas reconhecidas, capazes de eliminar os microrganismos mais freqüentemente envolvidos nas infecções em serviços de saúde. A maior desvantagem do álcool para a anti-sepsia da pele é seu efeito ressecante. Este estudo foi realizado na Clínica Renal de Santa Maria, RS, com ...

Despite having good efficacy in the treatment and prevention of tuberculosis, the administration of rifampicin (RIF) can cause serious side effects, resulting from the prolonged use of this substance. Thus, it is necessary to seek new systems for administering tuberculostatic drugs, to avoid unwanted adverse effects, increase their bioavailability and, consequently, improve their therapeutic efficacy. The present work describes the achievement of a pH-responsive system for RIF, using palygorskite, ...

The major problem with Chagas disease is evolution of the chronic indeterminate form to a progressive cardiac disease. Treatment diminishes parasitemia but not clinical progression, and the immunological features involved are unclear. Here, we studied the clinical course and the immune response in patients with chronic-phase Chagas disease at 48 months after benznidazole treatment. Progression to the cardiac form of Chagas disease or its aggravation was associated with higher in vitro antigen-specific ...

Isoniazid (INH) is one of the most effective first-line drugs in the treatment and prevention of TB. The present work studied the achievement of a pH-responsive system INH, using the palygorskite (PAL) as nanocarrier. The incorporation process was evaluated through a factorial design, in order to investigate the influence of some factors on the drug adsorption. The experiment using the maximum INH concentration (0.075 mg/mL), lower mass of PAL (300 mg) and lower pH (pH 2) was the most efficient compared ...

Abstract Silver vanadates have been widely investigated because of their many interesting properties and their potential use in several applications. In addition to this, a large number of groups have investigated silver vanadates in the form of nanostructures. Here, we address first the synthesis and properties of nanosilver vanadate. Different techniques, such as precipitation, thermal decomposition, hydrothermal treatment, and sol‐gel, are among the methods that have been employed for the controlled ...

The growth of the global population continues to increase the demand for energy. Petroleum-based fuels are the most used, resulting in very high emissions of greenhouse gasses. The aim of this present work was to undertake a kinetic study of the production of bio-hydrocarbons from oil sunflower, using catalysts composed of ordered mesoporous silica MCM-41 impregnated with cobalt and molybdenum oxides. The catalysts synthesized in this study underwent characterization using XRD, FRX, FTIR, SEM and ...

Blends of cellulose acetate (CA) and poly(3-hydroxybutyrate) (PHB) were prepared by the solvent-casting method in both the presence and the absence of a compatibilizer agent. The compatibilizer was synthesized by reactive processing between CA and PHB. From the differential scanning calorimetric analysis, it has been identified that CA/PHB blends are immiscible in the range of PHB content studied. The existence of interactions between the components was observed due to the displacement of glass transition ...
