-
(Sociedad Chilena de la Ciencia del Suelo, 2000)Entre los principales intereses mundiales hoy se tiene la gran conciencia del resguardo y recuperación de nuestros principales recursos naturales, entre los cuales es fundamental el sistema edáfico. Los suelos, con fines ...
-
(MARCEL DEKKER INC, 2003)Treatment of formylchromones, dissolved in 2-propanol with basic alumina at 75degreesC, selectively reduces the formyl group with good yields without any activation process of the alumina.
-
(Royal Society of Chemistry, 2018)A recombinant laccase from thermophilic bacteria was used to construct an enzyme-multi-walled carbon nanotube composite catalyst, which shows improved stability as a bio-electrocatalyst for the oxygen reduction reaction ...
-
(MDPI, 2020)Ezetimibe (EZ) is a poorly water-soluble drug with low bioavailability. Strategies such as solid dispersions (SD) and micellar systems (MS) were developed to identify the most effective drug delivery formulations with the ...
-
(2009)The slightly water-soluble flavonoid galangin (G) and its inclusion with either β-cyclodextrin (βCD), hydroxypropyl-β-cyclodextrin (HPβCD) or Heptakis-2,6-O-di methyl-β-cyclodextrin (DMβCD) were investigated. The stoichiometric ...
-
(Dove Medical Press, 2020)Introduction: Gold nanorods are highly reactive, have a large surface-to-volume ratio, and can be functionalized with biomolecules. Gold nanorods can absorb infrared electromagnetic radiation, which is subsequently dispersed ...
-
(Future Medicine, 2017)Aim: To improve the in vivo delivery of gold nanorods (GNRs) to the central nervous system of rats, these gold nanoparticles were conjugated to Angiopep-2, a shuttle peptide that can cross the blood-brain barrier. Materials ...
-
(2010)Background & aims: Gold nanoparticles (GNPs) have promising applications for drug delivery as well as for the diagnosis and treatment of several pathologies, such as those related to the CNS. However, GNPs are retained in ...
-
(Wiley-VCH Verlag, 2019)A novel and useful method to catalyze the electro-oxidation of nicotinamide adenine dinucleotide (NADH) over a glassy carbon electrode (GCE) modified with graphene oxide (GO) is presented. Based on the presence of oxygen ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2004-09-15)The in vitro growth inhibition activity of new thiosemicarbazone derivatives against the protozoan parasite Trypanosoma cruzi, the causative agent of American trypanosomiasis, are described. The designed compounds combine ...
-
(2009)Previously, we have identified a series of 5-nitroindazoles with good antiprotozoal activities, against Trypanosoma cruzi epimastigotes and Trichomonas vaginalis. Most of them have shown very low unspecific toxicity on ...
-
(MARCEL DEKKER INC, 1999)Dissolution profiles of theophylline (TP) from three types of sustained-release (SR) matrix tablets (plastic [PL], lipid [LP], and hydrophilic [HP]) in different dissolution media, with and without enzymes, were established ...
-
(Marcel Dekker Inc., 1999)Dissolution profiles of theophylline (TP) from three types of sustained- release (SR) matrix tablets (plastic [PL], lipid [LP], and hydrophilic [HP]) in different dissolution media, with and without enzymes, were established. ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 1997-06)A minimum of 460 nucleotides of 16S ribosomal RNA are needed to fold the target site for E. coli ribosomal protein S4, although a much smaller region within this large domain is protected from chemical reagents by the ...
-
(AMER CHEMICAL SOC, 2005-12-28)The effect on mycelial growth of the fungus Botrytis cinerea of a set of structurally related tricyclic hydroquinones [9,10-dihydroxy-4,4-dimethyl-2,3,5,8-tetrahydroantracen-1(4H)-one and 9,10-dihydroxy-4,4-dimethyl-5,8- ...
-
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2004-08)A standard aqueous extract of Mangifera indica L., used in Cuba as an antioxidant under the brand name of VIMANG(R), was tested in vivo for its anti-inflammatory activity using commonly accepted assays. M. indica extract, ...
-
(2004)A standard aqueous extract of Mangifera indica L., used in Cuba as an antioxidant under the brand name of VIMANG®, was tested in vivo for its anti-inflammatory activity using commonly accepted assays. M. indica extract, ...
-
(ELSEVIER SCIENCE BV, 1998-11-20)Basic fibroblast growth factor (bFGF) stimulated [H-3]thymidine incorporation at all stages of development, although the magnitude of this effect was the greatest in cells derived from pregnant mice. Cells primed with ...
-
(Nature, 2016)Growth and differentiation of ovarian follicles are regulated by systemic and local factors, which may include acetylcholine (ACh). Granulosa cells (GCs) of growing follicles and luteal cells produce ACh and in cultured ...
-
(Longman Group, 1992)A lithium carbonate controlled release tablet was evaluated in vivo and compared with a conventional lithium carbonate tablet. Changes in the first formulation were made in order to achieve a better performance. The ...
