Death-associated Protein 3 Regulates Mitochondrial-encoded Protein Synthesis and Mitochondrial Dynamics.

Mitochondrial morphologies change over time and are tightly regulated by dynamic machinery proteins such as dynamin-related protein 1 (Drp1), mitofusion 1/2, and optic atrophy 1 (OPA1). However, the detailed mechanisms of how these molecules cooperate to mediate fission and fusion remain elusive. DAP3 is a mitochondrial ribosomal protein that involves in apoptosis, but its biological function has not been well characterized.

Protective effect of grape seed extracts on human lymphocytes: a preliminary study.

Grape seed extracts (GSEs) possess a broad spectrum of antioxidative properties that protects various cells from free radicals and oxidative stress. In this study, the genoprotective effect of GSE on human lymphocytic DNA was studied using standard and lysed cell comet assays. Lymphocytes from 5 healthy subjects were pretreated with GSE in different concentrations.

Subjective and photometric determination of bleaching outcomes.

Objective: Subjective and objective measures were used to determine the relative efficacy of 10% and 35% carbamide peroxide gels in bleaching extracted human teeth.

Method And Materials: Fifty-five teeth (premolars and molars) were sectioned longitudinally, and one-half of each tooth was assigned to group A (10%) and the other half to group B (35%). Prebleaching shades were evaluated subjectively by 5 experienced observers using standard shade tabs.

Brightness (value) sequence for the Vita Lumin Classic shade guide reassessed.

The purpose of this study was to locate the 16 shade tabs from the Vita Lumin 'Classic' shade guide within the quantitative Luminosity, R, G and B scales (0-255 scales) using Photoshop software. A new value order arranged according to the Photoshop scale demonstrated a more linear relationship between the 16 shade tabs than the order given by the manufacturer. A Brightness Index representing the percentage difference in value between pairs of reordered shade tabs is suggested as a more realistic determinant of change in shade tab value.
