Selective defects in channel permeability associated with Cx32 mutations causing X-linked Charcot–Marie–Tooth disease

Neurobiology of Disease, 2006
The X-linked form of Charcot–Marie–Tooth disease (CMTX) is caused by mutations in connexin32 (Cx32), a gap junction protein expressed by Schwann cells where it forms reflexive channels that allow the passage of ions and signaling molecules across the ...

Method of calculation of the magnetic induction of the stator winding of a spiritual synchronous motor [PDF]

E3S Web of Conferences, 2023
This article discusses the calculation of the magnetic fields of the differential scattering of the stator, passing in the radial direction (penetrating the body of the rotor core), taking into account the saturation nonlinearities of the tooth zones of ...

In Vitro Evaluation of the Effect of Different Luting Cements and Tooth Preparation Angle on the Microleakage of Zirconia Crowns

International Journal of Dentistry, 2021
Introduction. Discrepancy between the crown border and prepared tooth margin leads to a microleakage that eases the penetration of microorganisms and causes the dissolution of luting cement consequently.

Tumor necrosis factor-α enhances the expression of vascular endothelial growth factor in a mouse orthodontic tooth movement model

Journal of Dental Sciences, 2022
Background/purpose: Tooth movement that is achieved using orthodontic mechanical principles relies on bone resorption which takes place on the compression side via osteoclasts. Tumor necrosis factor-α (TNF-α) has been known to affect osteoclast formation

Effect of erosive and abrasive stress on sealing ability of different desensitizers: In-vitro study.

PLoS ONE, 2019
This in vitro study examined the sealing ability of different desensitizing agents under a chemo-mechanical stress condition. For the study, a total of 144 extracted, caries-free human third molars were used to produce 1 mm-thick dentin discs.

Assessment of Enamel Permeability Using Scanning Electron Microscopy in Permanent Teeth with and without Molar Incisor Hypomineralisation- An In Vivo Study [PDF]

Journal of Clinical and Diagnostic Research, 2020
Introduction: Molar Incisor Hypomineralisation (MIH) is a qualitative defect of enamel which is more prone to posteruptive enamel breakdown resulting in the early invasion of dental caries compared to a normal enamel tooth structure.

Effect of Pore-Scale Mineral Spatial Heterogeneity on Chemically Induced Alterations of Fractured Rock: A Lattice Boltzmann Study

Geofluids, 2018
Fractures are the main flow path in rocks with very low permeability, and their hydrodynamic properties might change due to interaction with the pore fluid or injected fluid.
