Submucosal Pressure Ejection Endoscopic Dissection (SPEED): A New Technique in Increasing the Safety and Efficacy of ESD (With Video)

Journal of Digestive Diseases, EarlyView.
Submucosal pressure ejection endoscopic dissection (SPEED) technique combines pressure injection, incision, dissection, and coagulation, avoids frequent device exchange and ensures an easier and smoother procedure during dissection. In this study, the SPEED group showed a significantly lower application of hemostatic forceps, a shorter median resection

Effects of Calcium Hydroxide Paste and Access Cavities on Fracture Strength of Mature and Simulated Immature Human Teeth: Ex Vivo

Australian Endodontic Journal, EarlyView.
ABSTRACT The aim was to examine whether a Ca(OH)2 paste affects fracture strength of teeth. Sixty extracted maxillary central incisors were prepared to simulate immature teeth. Another 40 were used as mature teeth. The ten groups (n = 10) were: (1) immature control; (2) immature + access; (3) immature + access + 1 m Ca(OH)2; (4) immature + access + 12 ...

Submerged geomorphic record of Quaternary palaeoshorelines: terraces and clinothems along a shelf‐edge in the Žirje Archipelago, Adriatic Sea

Boreas, EarlyView.
Numerous studies have shown that during the Quaternary there were substantial fluctuations in sea level in response to glacial–interglacial climate variability, reaching lowstand positions up to 134 m below the present sea level (b.s.l.). These fluctuations have had a strong influence on the morphology of shallow shelf seas, which preserve evidence of ...

Assessing responses of reef island seabirds to environmental and anthropogenic drivers

Conservation Biology, EarlyView.
Abstract Tropical insular ecosystems face escalating, cumulative impacts of land‐ and sea‐based ecological threats that jeopardize the long‐term sustainability of their native communities. This joint vulnerability is epitomized by reef island seabirds, which are exposed to reef decline and coastal erosion driven by climate change, reduction in prey ...

Using Long‐Term Monitoring Data to Assess Temporal Patterns in Fish Community Assemblages in Florida Lakes

Fisheries Management and Ecology, EarlyView.
ABSTRACT In an effort to increase the relevancy of fish community data for management, we used fish community data to conduct a statewide assessment of Florida's freshwater fisheries resources and compare the relationships between environmental factors and freshwater fish communities over time.

Exploring the Impact of Ultrasonic Activation on the Antimicrobial Activity of Root Canal Sealers: A Year‐Long Ex Vivo Investigation Into Bacterial Survival

International Endodontic Journal, EarlyView.
ABSTRACT Aim This study investigated the long‐term survival of bacteria in root canals obturated using two endodontic sealers—AH Plus Jet (AHP) and BioRoot RCS (BCS)—while also assessing the influence of ultrasonic agitation on their antimicrobial effectiveness.

Characteristics of the Wall Pressure in Impacting Zone at the End of Vertical Plug

工程科学与技术, 2019
The vertical plug is a new way to dissipate water energy, in which the flow can be regarded as a submerged jet, and the construction leads to the high velocity and pressure on the wall.
