Preparation of Glass-Ionomer Cement Containing Ethanolic Brazilian

Andrade1* Plants may contain benefcial or potentially dangerous substances to humans. This study aimed to prepare and evaluate a new drug delivery system based on a glass‑ionomer‑Brazilian pepper extract composite, to check for its activity against pathogenic microorganisms of the oral cavity, along with its in vitro biocompatibility. The ethanolic Brazilian pepper extract (BPE), the glass‑ionomer cement (GIC) and the composite GIC‑BPE were characterized by scanning electron microscopy, attenuated total refectance Fourier transform infrared spectroscopy (ATR‑FTIR), and thermal analysis. The BPE compounds were identifed by UPLC–QTOF–MS/MS. The release profle of favonoids and the mechanical properties of the GIC‑BPE composite were assessed. The favonoids were released through a linear mechanism governing the difusion for the frst 48 h, as evidenced by the Mt/M∞ relatively to √t , at a difusion coefcient of 1.406 × 10–6 cm2 s−1. The ATR‑FTIR analysis indicated that a chemical bond between the GIC and BPE components may have occurred, but the compressive strength of GIC‑BPE does not difer signifcantly from that of this glass‑ionomer. The GIC‑BPE sample revealed an ample bacterial activity at non‑cytotoxic concentrations for the human fbroblast MRC‑5 cells.

Phytonutrient Bioaccessibility and Metabolism in Vitro and in Vivo Dorrain Low Yanwen B.App.Sci
Phytonutrient bioaccessibility and metabolism in vitro and in vivo Dorrain Low Yanwen B.App.Sci. (Food Science and Nutrition) (Hons) A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2015 Queensland Alliance for Agriculture and Food Innovation, Centre for Nutrition and Food Sciences. i Abstract Mangoes and bananas, two of Queensland’s major tropical crops are sources of bioactive phytonutrients linked to dietary health based on antioxidant, cardio-protective and vasodilatory properties. Bioaccessibility of macro-, micro- and phytonutrients from whole foods is first determined by mastication followed by gastrointestinal liberation from food matrices (cell wall and membrane). Intact plant cell walls effectively encapsulate cellular components e.g. starch, lipid, protein, carotenoids and polyphenols, physically preventing entry of the mammalian digestive system, which is unable to enzymatically break down plant cell walls. Once bioaccessible, ‘free’ nutrients are available for absorption, while the unreleased fraction travels to the colon for fermentation. Nutritional recommendations are usually based on extracted contents of raw plant material; therefore true dietary concentrations have not been well established. This thesis focuses on studying the effects of sequential digestive processing of mango (Kensington Pride) and banana (Cavendish) flesh in the mouth, stomach, small intestine and colon using in vitro and in vivo approaches. In vitro nutrient bioaccessibility studies often favour mechanical processing over mastication. Investigating the effect of mastication (Chapter 3) in mango demonstrated microstructural changes, conferring a range of chewed particle sizes (large particle clusters to cell fragments). Actions not replicable with a cutting blade i.e. compression, squashing and formation of bolus were observed in these masticated particles, collectively enhancing encapsulation of carotenoids.

Tannase cleaves the ester linkages between galloyl groups present in various compounds such as epigallocatechin and epigallocatechin gallate that are present in green tea leaves. The enzyme could be obtained from many sources starting from prokaryotes to higher eukaryotes. Vital minutiae such as regulation pathways, catalytic characteristics and other properties remain unrevealed which limits its usage in large scale. This study essentially elicits the information on tannase substrates, mechanism, applications, and the recent trends in the purification of tannase.
