(Public Library Science, 2013-12-01)
BackgroundNocardia sp. causes a variety of clinical presentations. The incidence of nocardiosis varies geographically according to several factors, such as the prevalence of HIV infections, transplants, neoplastic and ...
Imagens espectrais do processo de agregação da insulina por complexos metálicos luminescentes
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Química - PPGQCâmpus São Carlos, 2021-03-01)
Insulin is a protein hormone synthesized by β cells in the pancreas, which regulates the level of glucose in the blood. This protein was the first biopharmaceutical produced on an industrial scale for the treatment of ...

Methylparaben is an antimicrobial preservative widely used in formulations for personal care products and cosmetics. However, this compound is not monitored at sewage treatment plants, being considered as an emerging ...
How do methane rates vary with soil moisture and compaction, N compound and rate, and dung addition in a tropical soil?
(2018-01-01)
Soil moisture and compaction, and source of N and bovine urine can reduce methane (CH4) rates from agricultural soils. However, the magnitude of the effect is unknown in tropical soil under different conditions, as well ...
Isolamento de fungos a partir de solo com uso intenso de agroquímicos, visando a biorremediação
(Universidade Tecnológica Federal do ParanáMedianeiraBrasilTecnologia em Gestão AmbientalUTFPR, 2019-07-09)
An effective alternative is to reduce the risk areas of agrochemicals, which is not used for the recovery of degraded areas, is a bioremediation, which is fundamental for the use of living substances with the metabolism ...

Seleção de suportes para imobilização de lipases
(Universidade Tecnológica Federal do ParanáApucaranaBrasilLicenciatura em QuímicaUTFPR, 2020-08-27)
In this work, lipases (lip) from Burkholderia lata LBBIO-BL02 were immobilized on different supports, by physical adsorption and applied in ester hydrolysis reactions. The supports studied were: (1) Cobalt magnetic oxide ...
Molecular-level effects on cell membrane models to explain the phototoxicity of gold shell-isolated nanoparticles to cancer cells
(2020-10-01)
Metallic nanoparticles are promising agents for photothermal cancer therapy (PTT) owing to their photostability and efficient light-to-heat conversion, but their possible aggregation remains an issue. In this paper, we ...
Fast decolorization of azo dyes in alkaline solutions by a thermostable metal-tolerant bacterial laccase and proposed degradation pathways
(Springer Tokyo, 2020-07)
Biocatalytic decolorization of azo dyes is hampered by their recalcitrance and the characteristics of textile effluents. Alkaline pH and heavy metals present in colored wastewaters generally limit the activity of enzymes ...
