The aim of this research is to develop new mordants and a wide range of colors for natural dyeing of silk. In this study, two new erbium(ΙΙΙ) complexes, [Er(AO)(H2O)7](OAc)3 and [Er(AMH)(H2O)6](OAc)3 (AO = acridine orange, AMH = azomethine-H, and OAc = acetate anion), were synthesized, characterized and used as a mordant for the natural dyeing of silk yarns with an aqueous extract of green waln...

introduction: this study investigated the influence of erbium-doped yttrium aluminum garnet (er:yag) laser on microhardness, chemical composition and subsurface morphology of dentin cavity walls. methods: forty sound human premolars were selected and randomly assigned into four groups. class v cavities were prepared either with an er:yag laser (groups 1 and 2; 15 hz, 250 mj for enamel, 10 hz, 2...

introduction: this study aimed to assess the scanning electron microscope (sem) analysis of tooth surface irradiated by erbium:yttrium–aluminum–garnet (er:yag) laser with various parameters. methods: number of 25 extracted human third molars free of caries were used in this study. the teeth were put into 5 groups for laser irradiation as follows: group 1 (power: 0.5 w, energy: 50 mj); group 2 (...

Background and Aims Little is known about the outcomes of endoscopic resection (ER) for patients with colorectal adenomas (CRAs) high-grade dysplasia (HGD) or intramucosal cancer (IMCA). This study aimed to estimate rate local/malignant recurrence, identify predictive factors local recurrence (LR), evaluate treatment after ER HGD/IMCA. Methods A retrospective review was performed who underwent ...

n page 897, Luedeke et al. show that, like the plasma membrane, the ER can be compartmentalized into distinct membrane domains. In budding yeast, this separation restricts the diffusion of ER membrane proteins between the bud and the mother cell. The mRNAs of many bud-specific membrane proteins are actively transported into the bud. To keep these mRNAs and proteins in the bud, they must be kept...
