Binocular indirect ophthalmo microscope-assistant gas-perfused pars plana vitrectomy
The vitreous sample has been used for the diagnosis of uveitis and intraocular malignancy for decades. The sample volume is usually limited to 1 mL with current techniques. In the present study, a novel technique for higher amount of vitreous sample acquisition, that is, Binocular Indirect Ophthalmo Microscope-assistant gas-perfused pars plana vitrectomy (BAG-PPV) was invented.For diagnostic pu...

colorimeter which has been set at 0 optical density with water. Then the blank is read and the blank value deducted from the test value, the difference giving the turbidity due to fibrinogen. The fibrinogen concentration of the plasma can be read from the standard graph giving fibrinogen concentration against optical density. The only reagents used are normal saline and Parfentjev's ammonium su...

15 صفحه اولX-ray Microanalysis of Cultured Cells in the Scanning Electron Microscope and in the Scanning Transmission Electron Microscope: a Comparison
X-ray microanalysis of cultured cells as “whole mounts” (i.e., not sectioned) is used frequently e.g., to study mechanisms of ion transport. Cells can be cultured either on solid substrates or on thin plastic films on grids. Cells cultured on solid substrates are analyzed in the scanning electron microscope at relatively low accelerating voltage, cells cultured on thin films can be analyzed in ...
متن کاملBinocular Summation within the Binocular Visual Field
To study the influence of binocular summation on the threshold values of the central visual field in normal subjects, the authors modified the Octopus 201 by combining it with the space synoptophore. They tested ten normal subjects between 20 and 30 years of age. A space synoptophore was built into the cupola of the Octopus 201 so that the authors could confirm the conditions of binocular visio...
