(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 ...
-
(Frontiers Media, 2020)Ciprofloxacin is the choice treatment for infections caused by Salmonella Typhi, however, reduced susceptibility to ciprofloxacin has been reported for this pathogen. Considering the decreased approbation of new antimicrobials ...
-
Incident adverse drug reactions and their effect on the length of hospital stay in older inpatients (Springer, 2020)Background Acutely ill older persons are more likely to suffer adverse drug reactions, increasing morbidity, and mortality. The incident adverse drug reactions and their consequences on the length of hospital stay (LOS) ...
-
(MDPI AG, 2014)© 2014 Molecules. The numerous hydroxyl groups available in cyclodextrins are active sites that can form different types of linkages. They can be crosslinked with one another, or they can be derivatized to produce monomers ...
-
(2011)The physicochemical properties of 4-hydroxy-7-methoxy-3-phenyl-2H-chromen- 2-one (4HC) and β-cyclodextrins (CDs) inclusion complexes were investigated. The phase solubility profile of 4HC with β-cyclodextrin derivatives ...
-
(SPRINGER/PLENUM PUBLISHERS, 2010-10)The formation of the complexes of galangin (GAL) with native β-cyclodextrin (βCD), and with its substituted counterparts such as dimethyl-βCD (DMβCD) and hydroxypropyl-βCD (HPβCD), was studied by fluorescence spectra in ...
-
Inclusion complexes of estrone and estradiol with beta-cyclodextrin: Voltammetric and HPLC studies (WILEY, 2007-07)The interaction of estrone and estradiol with beta-cyclodextrins (beta CD) was investigated by differential pulse voltammetry (DPV) and high-performance liquid chromatography (HPLC) in mixed media. The co-solvent influence ...
-
(The Royal Society of Chemistry, 2012)Soluble pure silicon or germanium-containing poly(amide)s and their metallic composites (Cu or Au) were synthesized and characterized. Optical band gaps of pure polymer were comparable to an insulator behavior; however, ...
-
(Taylor & Francis, 2017)We explore the possibility of producing polymer nanocomposites with an ordered distribution of nanoparticles by using an electropolymerizable liquid crystal (LC) monomer. The nanoparticles are added to the monomer before ...
-
(2005)Phanerochaete chrysosporium has been thoroughly studied as a microbial model for lignin degradation. The enzymes lignin peroxidase (LiP) and manganese peroxidase (MnP), both encoded by several genes, play the main role in ...
-
(MDPI, 2020)The medium effect of the optical and catalytic degradation of methylene blue was studied in the NiO/SiO2, NiO/TiO2, NiO/Al2O3, and NiO/Na4.2Ca2.8(Si6O18) composites, which were prepared by a solid-state method. The new ...
