Pathogen displacement during intermittent catheter insertion: a novel in vitro urethra model.
(Wiley, 2019-11-29)
Aim: To develop a novel in vitro urethra model and use it to determine if insertion of an intermittent urinary catheter (IC) displaces pathogenic bacteria from the urethral meatus along the urethra. Methods: Displacement ...
Review of multifarious applications of Poly (lactic acid)
(Taylor & Francis, 2016)
Poly (lactic acid) is considered to be a promising alternative to petroleum-based polymers due to its renewability, biodegradability, biocompatibility, and good mechanical properties. Because of the high cost, the applications ...
A tough and novel dual-response PAA/P(NiPAAM-co-PEGDMA) IPN hydrogels with ceramics by photopolymerization for consolidation of bone fragments following fracture.
(IOP Science, 2019-07)
In this work, a novel dual-response hydrogel for enhanced bone repair following multiple fractures was investigated. The conventional treatment of multiple bone fracture consists on removing smaller bone fragments from the ...
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 ...
Development of alginate beads with encapsulated jabuticaba peel and propolis extracts to achieve a new natural colorant antioxidant additive.
(Elsevier, 2020-07)
This work aims to encapsulate anthocyanins and phenolic compounds extracted from a native Brazilian fruit peel
- jabuticaba (Plinia cauliflora (Mart.) Kausel) and propolis from Tubuna (Scaptotrigona bipunctata) stingless ...
Extended release of proteins following encapsulation in hydroxyapatite/chitosan composite scaffolds for bone tissue engineering applications.
(Elsevier, 2018-03)
Highlights:
Biocompatible, mechanically robust scaffold with an appropriate stability for bone healing when used with fixation device.
Proteins can be covalently attached to the scaffold.
Proteins are released for an ...
Enhancement of mechanical properties and wettability of TiO2NT arrays formed in simulated body fluid‐based electrolyte.
(Wiley, 2019-09-13)
Modified titanium nanotubes (TiO2NTs) coatings are grown in simulated body fluid (SBF) from Ticp and Ti6Al4V. The addition of 1% v/v of SBF to the electrolyte neither modifies film morphology nor the structural oxide ...
Platelet-rich plasma, Hydroxyapatite, and Chitosan in the bone and cartilaginous regeneration of femoral trochlea in rabbits: clinical, radiographic, and histomorphometric evaluations.
(Hindawi, 2018-06)
The aim of this study was to evaluate the trochlear bone and cartilaginous regeneration of rabbits using the association of PRP,
chitosan, and hydroxyapatite. Hole was made in rabbit troches, one hole in each animal ...
Analysis of the mechanical properties of solvent cast blends of PLA/PCL.
(Trans Tech Publications, 2014-09)
Polylactic acid (PLA) is the most promising material in the biodegradable category. However, brittleness and poor thermal stability restrict its application. To overcome this limitation, PLA may be blended with other ...
Micro-injection moulding of poly(vinylpyrrolidone-vinyl acetate) binary and ternary amorphous solid dispersions.
(MDPI, 2019-05)
Micro-injection moulding (µIM) was used for the production of enteric tablets of plasticised
and unplasticised solid dispersions of poly(vinylpyrrolidone-vinyl acetate) (PVPVA), and the effect
of the mechanical and thermal ...
