Physical properties of shellac material used for hot melt extrusion with potential application in the pharmaceutical industry
(MDPI, 2021-10-28)
Hot melt extrusion offers an efficient way of increasing the solubility of a poorly soluble
drug. Shellac has potential as a pharmaceutical matrix polymer that can be used in this extrusion
process, with further advantages ...
Injectable bone substitute based on chitosan with polyethylene glycol polymeric solution and biphasic calcium phosphate microspheres.
(Elsevier, 2020-06-10)
We described a method to produce an injectable bone substitute consisting of a solid and liquid phase, this solid was formed using the coacervation method consisting of a mixture of Hydroxyapatite (HAp) and beta-Tricalcium ...
β-glucan metabolic and immunomodulatory properties and potential for clinical application
(MDPI, 2020-12-10)
β-glucans are complex polysaccharides that are found in several plants and foods, including mushrooms. β-glucans display an array of potentially therapeutic properties. β-glucans have metabolic and gastro-intestinal effects, ...
Macro and micro routes to high performance bioplastics: bioplastic biodegradability and mechanical and barrier properties
(MDPI, 2021-06-30)
: On a score sheet for plastics, bioplastics have a medium score for combined mechanical
performance and a high score for biodegradability with respect to counterpart petroleum-based
plastics. Analysis quickly confirms ...
Green synthesis of zinc oxide nanoparticles: a review of the synthesis methodology and mechanism of formation.
(Elsevier, 2020-03)
Zinc oxide is of significant importance for many industries due to its versatile properties, which have been enhanced with the production of this material in the nanoscale. Nonetheless, the increase in concerns related to ...
Effect of thermal annealing on a bilayer polyvinyl alcohol/polyacrylic acid electrospun hydrogel nanofibres loaded with doxorubicin and clarithromycin for a synergism effect against osteosarcoma cells
(Elsevier, 2021-08-02)
Polyvinyl alcohol/polyacrylic acid (PVA/PAA) bilayer hydrogel nanofibres were successfully fabricated by
electrospinning and physically crosslinked via heat treatment. The effects of the thermal annealing
process on the ...
Treatment for the amelioration of persistent factors in complex anal fistula
(Springer, 2021-11-19)
Anal fistulae are abnormal hollow connections between the wall of the anal canal and the
perianal skin around the anus that have remained a burden on the medical sector for centuries.
The complexity of this disease is ...
Nanosuspension of pinhão seed coat development for a new high-functional cereal bar.
(Wiley, 2020-03-31)
The seeds from Araucaria angustifolia—commonly named as pinhão—are important culturally, and viable regional food from Brazil. Although now considered an endangered species, methods to increase the awareness of this tree ...
Antimicrobial PAA/PAH electrospun fiber containing green synthesized zinc oxide nanoparticles for wound healing
(MDPI, 2021-05-27)
Wound infections are the main complication when treating skin wounds. This work reports a novel antimicrobial material using green synthesized zinc oxide nanoparticles (ZnONPs) incorporated in polymeric fibers for wound ...
Upcycling biodegradable PVA/starch film to a bacterial biopigment and biopolymer
(MDPI, 2021-10-27)
Meeting the challenge of circularity for plastics requires amenability to repurposing post-use, as equivalent or upcycled products. In a compelling advancement, complete circularity for a biodegradable polyvinyl ...
