Bone digestion occurs when osteoclasts adhere onto bone surfaces and polarize to form acidic, hydrolase-rich resorption lacunae. For this process, they condense their actin-rich podosomes in tight belts to establish sealing zones, which segregate their basal membranes from those facing resorption lacunae. This polarization process remains poorly understood. Here, we combined quantitative proteo...

There were several materials used to seal different types of perforation defects. MTA is one of these restorative materials that is considered the most effective, biocompatible, non-toxic, and non-irritant; promote bone healing and cementum regeneration. The objective of this article was to review and summarize the sealing ability of MTA compared with the other materials used for sealing differ...

An Automated Road Maintenance Machine (ARMM) for automatically sealing pavement cracks has been developed by the University of Texas at Austin. Automating pavement crack sealing can improve safety, productivity and quality and reduce road user costs as well. Recent initial field trials of the full scale crack sealer have indicated that automated pavement crack sealing is now technically , econo...

Introduction: The aim of this study was to evaluate the sealing ability of Bioactive glass (BG) and Bioactive glass-Hydroxyapatite (BG-HA) in comparison to Mineral Trioxide Aggregate (MTA). Methods: The sealing ability of Bioactive glass and Bioactive glass-hydroxyapatite mixed with glass ionomer cement and Mineral Trioxide Aggregate used as retrograde filling material was assessed by bacterial...

Background: Energy sources have been an important part of surgery in achieving hemostasis and bloodless field to operate. Nowadays the most recent and commonly used are the bipolar vessel sealing system (LigaSure) and the harmonic scalpel (HS). Purpose: To do a comparative review between the LigaSure vessel sealing system and harmonic scalpel to make surgery faster, safer and better. Materials ...

Liquid sealing is an effective method to convert a fiber-optic refractometer into a simple and highly sensitive temperature sensor. A refractometer based on the thin-core fiber modal interferometer is sealed in a capillary tube filled with Cargille oil. Due to the thermo-optic effect of the sealing liquid, the high refractive-index sensitivity refractometer is subsequently sensitive to the ambi...

The various elements of federalism as well as other aspects of state organisation are interrelated. The isolation or sealing off of any of these facets could limit the possibility for necessary cross-topic adjustments or trade-offs. Therefore, coordination is necessary and the approach ‘nothing is decided until everything is decided’ tends to be favourable. Key Messages Federalism and Peace Med...

Blow/Fill/Seal technology, originally developed in Europe and introduced in the U.S. in the late 1960's, has emerged as a preferred method for aseptic packaging of pharmaceutical and healthcare products due to unrivaled flexibility in container design, overall product quality, product output and low operational costs. The Weiler design incorporates the multi-step process of blow molding, asepti...
