Bionanocomposites based on mesoporous silica and alginate for enhanced drug delivery
This work reports the preparation, the characterization and the prednisolone release profile of biocompatible hydrogel nanocomposites containing mesoporous silica (SBA) and alginate as a biomaterial for enhanced drug ...
The use of reverse transcription-PCR for the diagnosis of X-linked chronic granulomatous disease
(Associação Brasileira de Divulgação Científica, 2004)
Release of intermediate reactive hydrogen peroxide by macrophage cells activated by natural products
(Pharmaceutical Soc Japan, 2001-02-01)
By determining the hydrogen peroxide (H2O2) released in cultures of peritoneal macrophage cells from Swiss mice, we evaluated the action of 27 vegetable compounds (pristimerin, tingenone, jatrophone, palustric acid, lupeol, ...
Preparation and Characterization of Chitosan/mPEG-PCL Blended Membranes for Wound Dressing and Controlled Gentamicin Release
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2018-01-01)
In this paper, a novel wound dressing membrane for controlled release of gentamicin (GE), while covering and protecting the wound was investigated. Chitosan (CHI) was associated with methoxy polyethylene glycol - ...
Decrease in Cytotoxicity of Copper-Based Intrauterine Devices (IUD) Pretreated with 6-Mercaptopurine and Pterin as Biocompatible Corrosion Inhibitors
(American Chemical Society, 2013-02)
The copper intrauterine device (IUD) based its contraceptive action on the release of cupric ions from a copper wire. Immediately after the insertion, a burst release of copper ions occurs, which may be associated to a ...
Oleic, Linoleic and Linolenic Acids Increase ROS Production by Fibroblasts via NADPH Oxidase Activation

Gellan gum microspheres crosslinked with trivalent ion: Effect of polymer and crosslinker concentrations on drug release and mucoadhesive properties
Gellan gum microspheres were obtained by ionotropic gelation technique, using the trivalent ion Al3+. The percentage of entrapment efficiency ranged from 48.76 to 87.52% and 22 randomized full factorial design demonstrated ...
Cold stress induces metabolic activation of thyrotrophin-releasing hormone-synthesising neurones in the magnocellular division of the hypothalamic paraventricular nucleus and concomitantly changes ovarian sympathetic activity parameters
(BLACKWELL PUBLISHING, 2006-05)
Recent studies suggest thyrotrophin-releasing hormone (TRH) serves as a neurotransmitter and thereby provides a functional vegetative connection between the brain and the ovary. In the present study, magnocellular neurones ...
Controlled release of biomolecules from temperature-sensitive hydrogels prepared by radiation polymerization
(Elsevier Science BvAmsterdamHolanda, 2001)
