Microbiome of Apical Intracanal and Extraradicular Biofilms From the Same Roots of Teeth With Persistent Apical Periodontitis: An Observational Study

International Endodontic Journal, EarlyView.
ABSTRACT Aim Bacterial biofilms around the apex are crucial in disease progression and persistence of apical periodontitis. While intracanal biofilms initiate infection, extraradicular biofilms contribute to treatment resistance and persistence. Thus, a comprehensive understanding of these biofilms may help elucidate mechanisms underlying persistent ...

Study of the vibration frequency characteristics of tectonic coal containing assemblages at different loading rates

Scientific Reports
To reduce the vibration frequency superimposed on the original vibration frequency of a coal seam containing structural coal, damage to the coal structure should be reduced, and the occurrence of coal and natural gas outburst accidents should be ...

Prognostication of External Cervical Resorption Based on Heithersay's and Patel et al. Classifications: A Narrative Review

International Endodontic Journal, EarlyView.
ABSTRACT Background External cervical resorption (ECR) is a relatively rare form of tooth resorption. It is commonly classified either using two‐dimensional imaging according to the Heithersay or cone‐beam computed tomography using the Patel et al. classifications.

Rehabilitation in Cases of Maxillary Lateral Incisor Agenesis Using Zirconia Implant and Abutment: Finite Element Analysis and Systematic Review

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective The use of narrow‐diameter implants has emerged as a strategy to compensate for the reduced bone dimensions of maxillary lateral incisor agenesis (MLIA). This study integrates finite element analysis (FEA) and systematic review (SR) to assess the biomechanical and clinical viability of implant‐supported crowns in MLIA scenarios ...

Proteomic analysis of the zone of degeneration at the mitosis–meiosis transition stage in wild‐caught male catshark (Scyliorhinus canicula), correlated with an unusually high‐water temperature in the English Channel

Journal of Fish Biology, EarlyView.
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...

Effects of gill and muscle biopsies on the short‐term behaviour, exercise performance and survival of juvenile lake trout (Salvelinus namaycush)

Journal of Fish Biology, EarlyView.
Abstract Non‐lethal biopsy is a valuable tool for gaining insight into the physiological status of fish in the wild and for predicting their subsequent behaviour and survival. However, linking the insights from biopsy to post‐release behaviour relies on the assumption that the biopsy itself has no meaningful impact on post‐release behaviour or survival

STRUCTURAL DESIGN AND MOTION SIMULATION RESEARCH ON A NEW TYPE COMPOSITE ROTARY PERCUSSION DRILLING TOOL

Jixie qiangdu, 2017
A new type composite rotary percussion drilling tool was designed by studying the conversion mechanism of rotary to reciprocating motion. High-frequency axial impact and vibration was generated by an impact and energy transfer mechanism consisting of a ...

Flavobacterium oreochromis From Farmed Tambaqui (Colossoma macropomum): Insights Into Genetic, Phenotypic and Pathogenic Diversity

Journal of Fish Diseases, EarlyView.
ABSTRACT Flavobacterium spp. are the etiological agents of columnaris disease. Although there is evidence that columnaris poses a significant threat to the farming of tambaqui (Colossoma macropomum), there remains a large gap in understanding the genetic and phenotypic diversities of columnaris‐causing bacteria (CCB).
