Highly Structured Polyvinyl Alcohol Porous Carriers: Tuning Inherent Stability and Release Kinetics in Water
(American Chemical Society, 2018-02)
Polyvinyl alcohol (PVA) porous carriers were prepared by means of ice templating of aqueous solutions containing of 90 kD and/or 16 kD PVA. The carriers were loaded with traces of a colored probe (methyl orange) to screen ...
Development of alginate/starch-based hydrogels crosslinked with different ions: Hydrophilic, kinetic and spectroscopic properties
(2019-12-01)
Hydrogels are polymeric materials that have been applied in the controlled release system. The formation of the three-dimensional network may extend the release process. The objective of this study was to optimize the ...
Oregano essential oil encapsulation following the complex coacervation method: Influence of temperature, ionic strength, and ph on the release kinetics in aqueous mediumEncapsulação de óleo essencial de orégano pelo método de coacervação complexa: Influência da temperatura, força iônica e ph na cinética de liberação em meio aquoso
(2021-01-01)
Oregano essential oil (OEO) exhibits antimicrobial and antioxidant properties. The bioactive compounds of OEO are volatile. Thus, encapsulation helps in protecting the activity of the compound when exposed to harmful ...
Drug release profiles of modified MCM-41 with superparamagnetic behavior correlated with the employed synthesis method
(Elsevier Science, 2017-09)
Mesoporous materials with superparamagnetic properties were successfully synthesized by two different methods: direct incorporation (DI) and wet impregnation (WI). The synthetized solids were evaluated as host of drugs for ...
Differentially poised vesicles underlie fast and slow components of release at single synapses
(Rockefeller University Press, 2020)
In several types of central mammalian synapses, sustained presynaptic stimulation leads to a sequence of two components of synaptic vesicle release, reflecting the consecutive contributions of a fast-releasing pool (FRP) ...
Ciprofloxacin in Layered Double Hydroxides: Looking for the Best Synthesis Method
(Elsevier, 2021-10-12)
It is important to develop new methods of release to improve pharmacokinetic parameters of drugs, especially antibiotics, whose plasmatic concentration is determinant to ensure an effective treatment. Layered double ...
Ultrasound-assisted acid hydrolysis of cassava (Manihot esculenta) bagasse: Kinetics, acoustic field and structural effects
(2021-01-01)
Improving the actual acid hydrolysis of cassava bagasse (CB) with the assistance of high-intensity ultrasound (US) was aimed in comparison with mechanical agitation (AG). The kinetics of reducing and total sugar release ...
Steady-state analysis of enzymes with non-Michaelis-Menten kinetics: The transport mechanism of Na + /K + -ATPase
(American Society for Biochemistry and Molecular Biology, 2018-01)
Procedures to define kinetic mechanisms from catalytic activity measurements that obey the Michaelis-Menten equation are well-established. In contrast, analytical tools for enzymes displaying non-Michaelis-Menten kinetics ...
