(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 ...
-
(1985)1. 1. Liver microsomes from alloxan diabetic rats displayed decreased activity to hydroxylate testosterone only at the 2-α and 6-β positions. 2. 2. Diabetic insulin-treated rats showed higher hydroxylase activities than ...
-
(LIPPINCOTT WILLIAMS & WILKINS, 2005-12)In humans and rats, angiotensin I-converting enzyme activity is significantly determined by a gene polymorphism. Homozygous Brown Norway rats have higher plasma angiotensin I-converting enzyme activity and circulating ...
-
(COMPANY OF BIOLOGISTS LTD., 2011-07-15)Increasing evidence indicates that endoplasmic reticulum (ER) stress activates the adaptive unfolded protein response (UPR), but that beyond a certain degree of ER damage, this response triggers apoptotic pathways. The ...

-
(Springer Verlag, 2000)Senescence has been proposed as an important safeguard against neoplasia. One of the hallmarks of cellular senescence in vitro as well as human aging in vivo is a reduced intracellular protein catabolism. The pathways ...
-
(ENDOCRINE SOC, 2000-03)A form of polycystic ovary (PCO) resembling some aspects of the human PCO syndrome can be induced in rats by a single injection of estradiol valerate (EV). An increase in sympathetic outflow to the ovary precedes, by several ...

(ELSEVIER SCIENCE INC, 2009-03-10)Meeting Abstract
-
(Informa Healthcare, 1990)Reperfusion of rat kidney submitted to temporal ischaemia induces a decrease in glutathione content. Lipid peroxidation is not detected in kidney homogenates but microsomes obtained after periods of reperfusion longer than ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-05-15)A series of indazole N-oxide derivatives have been synthesized and their antichagasic and leishmanocidal properties studied. 3-Cyano-2-(4-iodophenyl)-2H-indazole N-1-oxide exhibited interesting antichagasic activity on the ...
-
(Hindawi, 2020)Four indole-3-carbaldehyde semicarbazone derivatives, 2-((5-bromo-1H-indol-3-yl)methylene)hydrazinecarboxamide (1), 2-((5-chloro-1H-indol-3-yl)methylene)hydrazinecarboxamide (2), 2-((5-methoxy-1H-indol-3-yl)methylene)hyd ...
