Spatially resolved quantum nano-optics of single photons using an electron microscope. [PDF]

open access: yesPhysical Review Letters, 2013
We report on the experimental demonstration of single-photon state generation and characterization in an electron microscope. In this aim we have used low intensity relativistic (energy between 60 and 100 keV) electrons beams focused in a ca.

Application of Electromyography Technology to Predict Chronic Diseases for COVID-19 Patients

open access: yesFrontiers in Biomedical Technologies
Purpose: Electromyography (EMG) is widely used to measure grip strength to evaluate neuromuscular activity, and thus it is possible to predict the health status of the heart muscle of those infected with the Coronavirus (COVID-19) and the extent of its ...

THE USE OF LEAD CITRATE AT HIGH pH AS AN ELECTRON-OPAQUE STAIN IN ELECTRON MICROSCOPY

open access: yesJournal of Cell Biology, 1963
Aqueous solutions of lead salts (1, 2) and saturated solutions of lead hydroxide (1) have been used as stains to enhance the electron-scattering properties of components of biological materials examined in the electron microscope.

High-resolution, high-throughput imaging with a multibeam scanning electron microscope

open access: yesJournal of Microscopy, 2015
Electron–electron interactions and detector bandwidth limit the maximal imaging speed of single‐beam scanning electron microscopes. We use multiple electron beams in a single column and detect secondary electrons in parallel to increase the imaging speed

Estimation of Complement Components (C3 and C4) and hs-CRP Level in Kidney Failure Patients

open access: yesPolytechnic Journal, 2019
Several kidney diseases associated with complement activation. Complement activation occurs in progressive chronic kidney disease and may contribute to the chronic inflammation that is characteristically found in the kidney.

Correlative light-electron microscopy methods to characterize the ultrastructural features of the replicative and dormant liver stages of Plasmodium parasites

open access: yesMalaria Journal
Background The infection of the liver by Plasmodium parasites is an obligatory step leading to malaria disease. Following hepatocyte invasion, parasites differentiate into replicative liver stage schizonts and, in the case of Plasmodium species causing ...

Shortfalls in the peptidyl-prolyl cis–trans isomerase protein Pin1 in neurons are associated with frontotemporal dementias

open access: yesNeurobiology of Disease, 2004
The peptidyl-prolyl cis–trans isomerase (PPIase) Pin1 modulates the activity of a range of target proteins involved in the cell cycle, transcription, translation, endocytosis, and apoptosis by facilitating dephosphorylation of phosphorylated serine or ...

Combined crystal-storing histiocytosis, light chain proximal tubulopathy, and light chain crystalline podocytopathy in a patient with multiple myeloma: a case report and literature review

open access: yesRenal Failure, 2023
Background Crystal-storing histiocytosis (CSH), light chain proximal tubulopathy (LCPT), and light chain crystalline podocytopathy (LCCP) are rare complications of multiple myeloma (MM) or monoclonal gammopathy of renal significance, and their diagnoses ...
