Understanding DNA Organization in the Nucleus By Fluorescence Microscopy and Energy Filtered Transmission Electron Microscopy

Interaction of lithium and gentamicin in salivary gland by electron microscopy and protein and DNA measurement

  The effects of gentamicin, lithium and combination of these drugs on ultrastructural morphology of rat submandibular glands were studied. Daily intraperitoneal injection of 40 mg/kg of gentamicin which causes chronic salivary gland toxicity, led to a marked decrease in gland's dry weight and total protein concentration but did not affect DNA content. Electron micrograph (EM) of submandibular ...

Energy-Filtering Transmission Electron Microscopy

Examination of Lung Parenchyma by Electron Microscopy

In this paper many of the principal struc­ture of the Moral Lung were studied with the help of Electron Microscopy. Detailed descrip­tion was given of Granular Pneumocytes, Membranous Pneumocytes, Macrophages, and Alveolar Capillaries. A discussion followed on the form and function of Granular Pneumo­cytes.  Acknowledgements  I am grateful to the Reza Shah Pahlavi Foundation for its generou...

High-Resolution Surface Plasmon Imaging of Gold Nanoparticles by Energy Filtered Transmission Electron Microscopy

We demonstrate the imaging capabilities of energy-filtered transmission electron microscopy at high energy resolution in the low energy-loss region, reporting the first direct image of a surface plasmon of an elongated gold nanoparticle at energies around 1 eV. Using complimentary model calculations performed within the boundary element method approach we can assign the observed results to the ...

Inelastic electron scattering observation using energy filtered transmission electron microscopy for silicon -- germanium nanostructures imaging.

This paper presents a new technique using energy filtered TEM (EFTEM) for inelastic electron scattering contrast imaging of Germanium distribution in Si-SiGe nanostructures. Comparing electron energy loss spectra (EELS) obtained in both SiGe and Si single crystals, we found a spectrum area strongly sensitive to the presence of Ge in the range [50-100 eV]. In this energy loss window, EELS spectr...
