Evaluating the efficacy of desensitizing dentifrices on dentinal hypersensitivity management: A scanning electron microscopic analysis

open access: yesJournal of Indian Society of Periodontology, 2021
Introduction: Dentin hypersensitivity (DH) adversely affects quality of life by impairing the ability to eat and drink certain foods, therefore, should be addressed promptly with a contingency plan that includes initial treatment with a noninvasive ...

Cathodoluminescence studies of phosphors in a scanning electron microscope [PDF]

open access: yes, 2015
Cathodoluminescence studies are reported of phosphors in a field emission scanning electron microscope (FESEM). A number of phosphor materials have been studied and exhibited a pronounced comet-like structure at high scan rates, because the particle ...

A Scanning Electron Microscope for Ultracold Atoms

open access: yes, 2006
We propose a new technique for the detection of single atoms in ultracold quantum gases. The technique is based on scanning electron microscopy and employs the electron impact ionization of trapped atoms with a focussed electron probe.

THE SCANNING ELECTRON MICROSCOPE

open access: yesThe Sciences, 1967
The scanning electron microscope combines the techniques of the cathode-ray tube and the conventional electron microscope?both considered indispensable to modern technology. The SEM, which presents a picture having a distinct three-dimensional appearance, is finding application in the examination of wood fibers in connection with paper manufacture, of ...

Multicolour correlative imaging using phosphor probes [PDF]

open access: yes, 2015
Correlative light and electron microscopy exploits the advantages of optical methods, such as multicolour probes and their use in hydrated live biological samples, to locate functional units, which are then correlated with structural details that can be ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

A case of trichorrhexis nodosa

open access: yesPifu-xingbing zhenliaoxue zazhi, 2022
We report a case of trichorrhexis nodosa. A 27-year-old female presented with white nodules of hair that were easily broken for 17 years. Dermatological examination showed that the hair was sparse, dry, and there were many tiny granular white nodules ...

PARP inhibition and pharmacological ascorbate demonstrate synergy in castration‐resistant prostate cancer

open access: yesMolecular Oncology, EarlyView.
Pharmacologic ascorbate (vitamin C) increases ROS, disrupts cellular metabolism, and induces DNA damage in CRPC cells. These effects sensitize tumors to PARP inhibition, producing synergistic growth suppression with olaparib in vitro and significantly delayed tumor progression in vivo. Pyruvate rescue confirms ROS‐dependent activity.
