OBJECTIVES The purpose of this in vitro study was to evaluate the microleakage and penetration of fissure sealant in permanent molar teeth with fluorosis after pretreatment of the occlusal surface. MATERIALS AND METHODS A total of 120 third molars with mild dental fluorosis were randomly divided into 6 groups (n = 20). The tooth surfaces were sealed with an unfilled resin fissure sealant (FS)...

Kanaka Maoli (Indigenous Hawaiians) are blessed with a written literature that documents observations and relationships their environment in the form of chants, stories, genealogies passed down orally for centuries. These literatures connect them to ancestral knowledge highlight species, places, processes importance. Such sayings as Pua ka wiliwili, nanahu manō (When wiliwili blossoms, sharks b...

Shq1 is a conserved protein required for the biogenesis of eukaryotic H/ACA ribonucleoproteins (RNPs), including human telomerase. We report the structure of the Shq1-specific domain alone and in complex with H/ACA RNP proteins Cbf5, Nop10 and Gar1. The Shq1-specific domain adopts a novel helical fold and primarily contacts the PUA domain and the otherwise disordered C-terminal extension (CTE) ...

Merrill et al. (1) propose 8900 BP as the latest date Proto-UtoAztecan (PUA) was spoken. Based on negative reconstructive evidence, they argue for a PUA homeland in the US Great Basin, observing that “a significant decrease in effective moisture” beginning in 6900 BC motivated bands to leave the region, leading to the language’s breakup. Given a Great Basin homeland, such a very early date is a...

In recent years many transformations have occurred in Iranian society and women and girls still have a lot of worries about comes to urban public spaces. Also, due to some ambiguities in defining the domain of public space in traditional Islamic cities and gaps in the knowledge related to the Kurdish cities, the main problem of this paper is how we can define a participatory approach to improve...

Abstract Liquid-crystal display(LCD) 3D printing, also known as light during printing or photopolymer is a type of additive manufacturing technology that uses light-sensitive resin to create three-dimensional objects. This has gained popularity in recent years owing its ability high-resolution, detailed objects with wide range materials, including shape-memory polymers, toughness resins, and el...
