Vitamins A and D and zinc affect the leshmanicidal activity of canine spleen leukocytes
(2021-09-01)
Canine leishmaniasis (CanL) is a chronic disease caused by Leishmania infantum, and the limitations of the current treatments have encouraged new alternatives, such as the use of immunomodulatory nutrients. The objective ...
Zinc and cadmium biosorption by untreated and calcium-treated Macrocystis pyrifera in a batch system
(Elsevier, 2012-07)
Zinc and cadmium can be efficiently removed from solutions using the brown algae, Macrocystis pyrifera. Treatment with CaCl 2 allowed stabilization of the biosorbent. The maximum biosorption capacities in mono-component ...
Design and characterization of polymer-based nanoparticles loaded with zinc phthalocyanine for use in photodynamic therapy
(Universidade Federal de Santa MariaBrasilQuímicaUFSMPrograma de Pós-Graduação em QuímicaCentro de Ciências Naturais e Exatas, 2021-10-08)
Zinc phthalocyanine (ZnPc) is a promising second-generation photosensitizer (PS) that exhibits advantageous properties that include low toxicity, high chemical and photochemical stability, strong absorption in the red ...
Trypanosoma cruzi: The effects of zinc supplementation in the immune response during the course of experimental disease
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2009)
Zinc is an essential nutritional component required for normal development and maintenance of immune functions. The possible effects of zinc in upregulating the host immune response during the acute and chronic phases of ...
Flow-injection solid-phase spectrophotometry for the determination of zinc in pharmaceutical preparations
(Elservier, 1999)
A flow system exploiting solid-phase spectrophotometry is proposed for the determination of zinc in pharmaceutical preparations. The chromogenic reagent 1-(2-tiazolylazo)-2-naphthol (TAN) was immobilized on C18 bonded ...
Development and characterization of novel ZnO-loaded electrospun membranes for periodontal regeneration
(Elsevier B.V., 2015-09-01)
Objectives. This study reports on the synthesis, materials characterization, antimicrobial capacity, and cytocompatibility of novel ZnO-loaded membranes for guided tissue/bone regeneration (GTR/GBR). Methods. Poly(epsilo ...
Crown fracture: Failure load, stress distribution, and fractographic analysis
(Elsevier B.V., 2015-09-01)
Statement of problem. The outcomes from load-to-failure tests may not be applicable to clinical situations. Purpose. The purpose of this study was to critically evaluate the efficacy of load-to-failure tests in the ...
Application of three-variables Doehlert matrix for optimisation of an on-line pre-concentration system for zinc determination in natural water samples by flame atomic absorption spectrometry
(Elservier, 2003)
This article describes an on-line pre-concentration system for zinc determination in environmental samples by
flame atomic absorption spectrometry (FAAS).It was based on the sorption of zinc(II) ions in a minicolumn ...
Cadmium and Zinc Biosorption by Macrocystis Pyrifera: Changes in the Biomass
(Trans Tech Publications, 2009-05)
Macrocystis pyrifera was used for the recovery of Zn2+ and Cd2+ from slightly acidic solutions (i.e., pH 4). Sorption isotherms were obtained from mono- and bi-component solutions. For the study of metal desorption, EDTA, ...
Photosensitizer-Loaded Magnetic Nanoemulsion for Use in Synergic Photodynamic and Magnetohyperthermia Therapies of Neoplastic Cells
(AMER SCIENTIFIC PUBLISHERS, 2008)
In this study a magnetic nanoemulsion (MNE) was developed from a mixture of two components, namely biodegradable surfactants and biocompatible citrate-coated cobalt ferrite-based magnetic fluid, for entrapment of ...
