Extraction method plays critical role in antibacterial activity of propolis loaded hydrogels.
(Elsevier, 2016-03)
Extracted propolis has been used for a long time as a remedy. However, if the release rate of propolis is not controlled, the efficacy is reduced. To overcome this issue, extracted propolis was added to a cryogel system. ...
Reinforced polylactic acid for use in high strength biodegradable medical implants.
(2016)
Traditional medical implants, such as orthopedic screws, pins, and
coronary stents, are almost exclusively metallic due to high mechanical
strength requirements. However, issues related to the use of permanent
metallic ...
A novel pH‐sensitive ceramic‐hydrogel for biomedical applications.
(Wiley, 2015-12)
Innovations on the field of smart hydrogels are now being held with loads of advantages. With recent progress, smart polymers can now be used on the market for specific target/objectives desired on medicine. However, the ...
Preparation and characterization of novel poly(vinyl) (alcohol) (PVA) and poly(acrylic acid) (PAA) hydrogels for sensitive hydrogels.
(Sciforum, 2014-05)
Stimuli Sensitive hydrogels have enormous potential in various applications. Various
environmental variables are found in the body, such as low pH and elevated temperatures. For this
reason, either pH-sensitive and/or ...
In vitro fibroblast and pre-osteoblastic cellular responses on laser surface modified Ti-6AI-4V.
(IOP Publishing, 2014-12-29)
The success of any implant, dental or orthopaedic, is driven by the interaction of implant material with the surrounding tissue. In this context, the nature of the implant surface plays a direct role in determining the ...
Stability studies of hot-melt extruded ternary solid dispersions of poorly-water soluble Indomethacin with Poly(vinyl pyrrolidone-co-vinyl acetate) and polyethylene oxide.
(Elsevier, 2019-08)
This investigation aims to evaluate the effect of moisture and temperature on the physical
stability and dissolution behaviour of hot-melt extruded binary and plasticised ternary solid
dispersions. Poorly water-soluble ...
Faster release of lumen-loaded drugs than matrix-loaded equivalent in polylactic acid/halloysite nanotubes.
(MDPI, 2019-06-15)
Nanocomposite-based drug delivery systems with intrinsic controlled release properties are of great interest in biomedical applications. We report a novel polylactic acid (PLA)/halloysite nanotube (HNT) nanocomposite-based ...
Surface modified halloysite nanotubes reinforced polylactic acid for use in biodegradable coronary stents.
(Wiley, 2019-08)
Poly(lactic acid) (PLA) was reinforced halloysite nanotubes (HNTs) in this study. To improve dispersion and interfacial adhesion of HNTs within the PLA matrix, HNTs were surface modified with 3‐aminopropyltriethoxysilane ...
Mechanical properties of anodic titanium films containing ions of Ca and P submitted to heat and hydrothermal treatment.
(Elsevier, 2016-12)
Anodic oxidation is a technique widely used to improve the bioactivity of Ti surface. In this study, micro-arc oxidation (MAO) was used to obtain an anodic film incorporating Ca and P ions to evaluate the effect of heat ...
Alfa fiber/polypropylene composites: Influence of fiber extraction method and chemical treatments.
(Wiley, 2019-01)
Alfa fiber/polypropylene composites were manufactured using twin-screw extrusion. Fibers were extracted following alkaline and steam explosion methods. Three chemical treatments were also applied to alkaline extracted ...
