Gold nanoparticles for photothermally controlled drug release
(Future Medicine Ltd., 2014)
© 2014 Future Medicine Ltd. In this article, we describe how nanoparticles work in photothermally triggered drug delivery, starting with a description of the plasmon resonance and the photothermal effect, and how this is ...
Chronopharmacokinetics of theophylline administered as a controlled-release tablet
(1996)
The result obtained from different studies of the chronopharmacokinetics of some controlled-release tablets of theophylline are variable, since some authors report differences while others do not. At our laboratory we have ...
Heme Iron Release from Alginate Beads at In Vitro Simulated Gastrointestinal Conditions
(Humana Press Inc., 2016)
Heme iron (Fe) release from alginate beads at in vitro simulated gastrointestinal conditions for potential use as oral heme Fe supplement was studied. Five beads at different ratios of sodium alginate (SA)-to-spray-dried ...
Release Kinetic in Yogurt from Gallic Acid Microparticles with Chemically Modified Inulin
(Institute of Food Technologists, 2015)
Gallic acid (GA) was encapsulated with native (NIn), cross-linked (CIn) and acetylated (AIn) inulin by spray-drying. Inulin microparticles were characterized by encapsulation efficiency (EE) and their release profile in ...
Exploring the influence of diels–alder linker length on photothermal molecule release from gold nanorods
(Elsevier, 2018-06)
We studied the photothermal release of carboxyfluorescein (CF) linked to the gold surface of gold nanorods (GNRs) by two Diels-Alder adducts of different lengths (n = 4 and n = 9). The functionalized GNRs were irradiated ...
alpha(2)-adrenoceptors control the release of noradrenaline but not neuropeptide Y from perivascular nerve terminals
(ELSEVIER SCIENCE INC, 2002-09)
Neuropeptide Y (NPY) and noradrenaline (NA) are co-transmitters at many sympathetic synapses, but it is not yet clear if their release is independently regulated. To address this question, we quantified the electrically ...
Antimicrobial polymer composites with copper micro- and nanoparticles: Effect of particle size and polymer matrix
(SAGE, 2015)
The addition of metal particles, for instance, silver or copper, into polymer matrices is a relevant strategy producing novel antimicrobial materials. By using two particles with diameters around 10nm and 45 mu m, and ...
Fluoride release from fissure sealants
(1997)
This 30-day study, compared the amounts and patterns of fluoride release from 5 commercially available fluoride-containing pit and fissure sealants: FluroShield, Helioseal-F, Ultraseal XT, Baritone L3, and Teethmate-F; ...
DESIGN AND EVALUATION OF A CONTROLLED-RELEASE THEOPHYLLINE TABLET - PRELIMINARY COMMUNICATION
(SOC CHIMICA ITALIANA, 1989-11)
A 300 mg controlled-reelase theophylline formulation was developed as a tablet prepared by wet granulation using the acrylic resins Eudagrit S 100R and Eudagrit RSPMR. The tablet was compared with a marketed controlled-release ...
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 ...
