So far, there is no report regarding the micro-Raman vibrational fingerprint of the bonds between 10-methacryloyloxy-decyl dihydrogen phosphate (10-MDP) and zirconia ceramics. Thus, the aim of this study was to identify the Raman vibrational peaks related to the bonds of 10-MDP with zirconia, as well as the influence on microshear bond strength. Micro-Raman spectroscopy was employed to assess the vibrational peak of 10-MDP binding to zirconia.

Material And Methods: Thirty-two male Wistar rats (270-310g) were randomly distributed in four groups (n=8/group): the sham control group and the negative control group received saline; the high omega-6/low omega-9 group received isolipid fatty acid with high ω-6:ω-3 ratio and low ω-9:ω-6 ratio; the high omega-3/low omega-6 group received fatty acid with low ω-6:ω-3 ratio and high ω-9:ω-6 ratio. Saline and oils were administered by gavage for 4days before exodontia and 3days after surgery, followed by euthanasia.
Purpose: To evaluate the antioxidant and antiperoxidative effects of oil mixes of high ratio Omega-9:Omega-6 and low ratio Omega-6:Omega-3 in the third day after tooth extraction in rats.
Methods: Thirty-two male Wistar rats (270-310 g) were randomly distributed in two groups: Control (n=24) and Test (n=8). Control group was divided into three subgroups (n=8): G1: Sham-Saline; G2: Saline; G3: Isolipid.
Purpose: To evaluate the effect of bioflavonoid ternatin (TRT) on rat liver regeneration and oxidative stress after 70% partial hepatectomy (PH).
Methods: Thirty six young male Wistar rats were randomly assigned to two groups of 18 animals each - control (G1) and experimental (G2) - and were submitted to PH under inhalatory diethylether anesthesia. G1 rats received daily intraperitoneal (ip) injections of saline (NaCl 0.
Objective: To study the effects of polyunsaturated fatty acids (PUFA) omega-3 and omega-6 in the oxidative stress and in liver regeneration in rats subjected to 70% partial hepatectomy (PH, 70% hepatectomy, Higgins-Anderson partial hepatectomy).
Methods: 72 young male Wistar rats were randomly divided into four equal-sized groups: control (G1), partially hepatectomized (G2), partially hepatectomized with two weeks daily intraperitoneal infusion of omega-3 (G3) and partially hepatectomized with two weeks daily intraperitoneal infusion of omega-6 (G4). In moments 36 h (T1), 168 h (T2) and 336 h (T3) post-PH, thiobarbituric acid reactive substances (TBARS) and reduced glutathione (GSH) were measured in plasma and liver tissue, while glucose and total bilirubin were measured in blood.
