Effect of Additives on Mineral Trioxide Aggregate Setting Reaction Product Formation [PDF]

, 2015
Introduction Mineral trioxide aggregate (MTA) sets via hydration of calcium silicates to yield calcium silicate hydrates and calcium hydroxide (Ca[OH]2). However, a drawback of MTA is its long setting time.

Valorization of Yacon (Smallanthus sonchifolius) peel for peroxidase production and its immobilization on alginate beads for 2,4‐dichlorophenol bioconversion

The Canadian Journal of Chemical Engineering, EarlyView.
Sodium alginate was modified with EDC/NHS for the immobilization of Yacon peel peroxidase, resulting in a novel biocatalyst for the oxidation of 2,4‐dichlorophenol. Abstract Yacon (Smallanthus sonchifolius) roots are emerging as an alternative source of peroxidase. This study aimed to extract, immobilize, and characterize the peroxidase from Yacon peel,

Nanomagnetic-Mediated Drug Delivery for The Treatment of Dental Disease [PDF]

, 2018
Maintaining the vitality of the dental pulp, the highly innervated and highly vascular, innermost layer of the tooth, is a critical goal of any dental procedure. Upon injury, targeting the pulp with specific therapies is challenging because it is encased

Spouted bed drying parameters and adjuvant effects on polyphenol retention and antioxidant activity in mango peel powders

The Canadian Journal of Chemical Engineering, EarlyView.
Spouted bed drying of mango peels with colloidal SiO2 and corn starch produces a free‐flowing powder with reduced agglomeration, increased drying yield, and preserved antioxidant and polyphenol content. Abstract The production of polyphenol‐rich powders is a promising strategy for valorizing agro‐industrial byproducts. This study evaluated drying yield,

Dental development in the tropical gar (Atractosteus tropicus) and the evolution of vertebrate dentitions

Developmental Dynamics, EarlyView.
Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.
