Micro-CT evaluation of apical delta morphologies in human teeth. [PDF]

Sci Rep, 2016
The apical delta is an intricate system within the root canal and incompletely debridement may affect the long-term prognosis of root canal therapy. The aim of the present study is to investigate the morphologic features of apical deltas in human teeth ...

Structural heterogeneity and dynamics in the apical stem loop of s2m from SARS-CoV-2 Delta by an integrative NMR spectroscopy and MD simulation approach. [PDF]

Nucleic Acids Res
In structured RNAs, helical elements are often capped by apical loops that are integral structural elements, ranging from 3 to >20 nts of size on average, and display a highly heterogeneous energy landscape profile, rendering structural characterization ...

Neuralized Promotes Basal to Apical Transcytosis of Delta in Epithelial Cells [PDF]

Molecular Biology of the Cell, 2010
In this article, it is shown that a pool of Delta localizes at the basolateral membrane of sensory organ precursor cells of Drosophila and of polarized MDCK cells and that Delta is endocytosed in a Neuralized-dependent manner from this basolateral ...

The formation of apical delta of the permanent teeth in dogs.

Journal of Veterinary Medical Science, 2001
To determine the process of formation of apical delta, a histological study on the permanent teeth was carried out in dogs. A litter of 7 clinically healthy beagle dogs and 33 adult dogs (4- to 15- year-old) of 12 breeds with periodontal disease were ...

Antibiotics for treatment of apical periodontitis, indication or contraindication

Bulletin of the National Research Centre, 2023
Background Apical periodontitis as an endodontic diagnosis has attracted attention for the close relationship between the periodontal nature and the endodontic nature that this pathology represents. The appearance of pathology in periodontal tissues, but

Delta-Notch Signaling: The Long and The Short of a Neuron’s Influence on Progenitor Fates

Journal of Developmental Biology, 2020
Maintenance of the neural progenitor pool during embryonic development is essential to promote growth of the central nervous system (CNS). The CNS is initially formed by tightly compacted proliferative neuroepithelial cells that later acquire radial ...

The Arp2/3 complex and WASp are required for apical trafficking of Delta into microvilli during cell fate specification of sensory organ precursors [PDF]

Nature Cell Biology, 2009
Cell fate decisions mediated by the Notch signalling pathway require direct cell-cell contact between adjacent cells. In Drosophila melanogaster, an external sensory organ (ESO) develops from a single sensory organ precursor (SOP) and its fate specification is governed by differential Notch activation.

Quantitative Evaluation of Apical Delta Morphologies in Mesial Roots of Mandibular First Molar Teeth: A Micro-CT Study

Turkiye Klinikleri Journal of Dental Sciences, 2017
ABS TRACT Objective: The apical delta is the branching of the main root canal dividing into three or more ramifications near the root apex, while the main canal itself becoming indistinguishable. Aim of this study was to analyze apical delta morphologies

Electrode impedance dynamics in sequential cochlear implant users: insights into cochlear immunity [PDF]

Frontiers in Immunology
IntroductionCochlear implant outcomes can be limited due to immunologically mediated intracochlear foreign body responses, resulting in new bone growth and fibrosis.
