(SOC BRASILEIRA QUIMICA, 2006-12)It is studied the extraction of cadmium( II) ions from acidic aqueous solutions using a stirred transfer cell-type emulsion liquid membrane ( ELM) prepared by dissolving in kerosene, with D2EHPA ( an alkylphosphoric acid) ...
-
(MDPI, 2021): Psoriasis is a chronic immunoinflammatory skin disease. Although its diagnosis is clinical, differences in the appearance and severity of lesions pose a challenge for clinicians worldwide. The use of accessible biomarkers ...
-
(Hospital Clinicas, Brasil, 2021)Monoclonal antibodies or fusion proteins, defined as biological drugs, have modified the natural history of numerous immune-mediated disorders, allowing the development of therapies aimed at blocking the pathophysiological ...
-
(ELSEVIER, 2008-05-15)Extraction of lanthanum, samarium and erbium into a microcapsule containing 2-ethylhexylphosphonic acid mono-2-ethylhexyl ester (EHPNA) is studied. The extraction kinetic model used to predict uptake curves is based on the ...
-
(MDPI, 2022)Rosacea is a chronic inflammatory skin disease whose prevalence rates remain unknown in Chile. Laboratory benchmark testing for this disease is not useful, therefore, we aimed to evaluate the gingival crevicular fluid (GCF) ...
-
(Elsevier, 2013)The aim of this work is the experimental and theoretical characterization of the mass transfer in a membrane-based dense gas extraction of metal ions from aqueous solutions using a hollow fiber contactor. Extractions of ...

-
(Wiley Periodicals, and the American Pharmacists Association, 2013)Putative colonic release formulations of calcium (Ca)-alginate coated with chitosan containing two different actives, prednisolone and inulin, were prepared in three different sizes, beads (D50 = 2104 :m) and microparticles ...
-
(Korean Society of Industrial Engineering Chemistry, 2019)The aim of this work is to produce a superparamagnetic core-shell adsorbent material composed of magnetite nanoparticles coated with a silica layer and functionalized with betaine for applications associated with the ...
-
(Elsevier B.V., 2019)© 2018 In this communication, adsorbents based on functionalized magnetite nanoparticles were synthetized, characterized and evaluated as adsorbents for the uptake of La (III), Pr(III) and Nd(III) from aqueous solutions. ...
-
(Elsevier, 2015)Background New therapeutic options are needed for patients with psoriasis. Tofacitinib, an oral Janus kinase inhibitor, is being investigated as a treatment for moderate-to-severe chronic plaque psoriasis. In this study, ...
-
(SOCIEDAD CHILENA DE QUIMICA, 2005-12)It is studied the uptake of Zn(II) and Cu(II) from acid aqueous solutions using microcapsules containing 2-ethylhexylphosphonic acid mono-2-ethylhexyl ester, a non-specific extractant, as an alternative method for metals ...
