Cichorium intybus from India: GC-MS Profiling, Phenolic Content and in vitro Antioxidant Capacity of Sequential Soxhlet Extracted Roasted Roots

Abstract Research on the bio-activities and chemical composition of roasted C. intybus roots from India is very little. In present studies GC-MS analysis of volatile components of roasted C. intybus roots, phenolics and flavonoid content estimation and antioxidant potential of roasted C. intybus roots wa...

Physicochemical, Thermal, Structural and Pasting Properties of Unconventional Starches from Ginger (Zingiber officinale) and White Yam (Dioscorea sp)

Abstract Ginger and white yam starches were investigated and compared with maize starch. Proximal composition, thermogravimetry, differential scanning calorimetry, microscopy, colourimetry, X-ray powder diffractometry and pasting profile were analysed. The unconventional starches presented higher protein...

Tucum-do-Pantanal (Bactris setosa Mart): Physicochemical Characterization of Almonds, Press Cake and Crude Oil

Abstract Brazil has high diversity of native fruits with high nutritional and biochemical value. Bactris setosa Mart. (tucum-do-Pantanal) stands out by its oil-rich almond. This study aimed to determine the physicochemical characteristics of tucum-do-Pantanal almond and its by-products: press cake and cr...

Influence of activation mode, fatigue, and ceramic interposition on resin cements' diametral tensile strength

Abstract This study evaluated the influence of activation modes, on Diametral Tensile Strength (DTS) of dual cured resin cements subjected to a Mechanical Fatigue test (MF). Four dual-cured resin cements (RelyX UNICEM [U], RelyX ARC [A], ENFORCE [E] and Nexus 2 [N]) were activated by three different curi...

Effect of peracetic acid used as single irrigant on the smear layer, adhesion, and penetrability of AH Plus

Abstract The aim of this study was to evaluate the effect of peracetic acid (PAA) as a single irrigant on the smear layer, on the intraradicular dentinal bond strength, and on the penetrability of an epoxy-based resin sealer into the dentinal tubules. A total of 120 roots were distributed into 4 groups a...

Microtensile bond strength of root canal dentin treated with adhesive and fiber-reinforced post systems

Abstract Nowadays, demand for esthetic restorations has risen considerably; thus, nonmetal esthetic posts made of either high-strength ceramics or reinforced resins, such as fiber-reinforced resin posts, have become more and more popular. Important characteristics of fiber-reinforced posts involve a modu...
