Electron microscopy of experimental uveitis.

The fine structural features of the early pathological changes induced in uveal tissue by single intravitreal injections of three different quantities of bovine serum albumin (BSA) in rabbits toere studied. Small quantities of antigen (BSA) did not produce clinical signs of uveitis but a mild leukocytic infiltration (mainly monocytes) was found in the base of the ciliary body. The occasional ba...

Experimental demonstration of scanned spin-precession microscopy.

We present a new tool for imaging spin properties. We show that a spatially averaged spin signal, measured as a function of a scanned magnetic probe's position, contains information about the local spin properties. In this first demonstration we map the injected spin density in GaAs by measuring spin photoluminescence with a resolution of 1.2  μm. The ultimate limit of the technique is set by t...

Atomic Force Microscopy in Food Research

of the food that we enjoy rely upon nanoor microscale phenomena. In addition, the importance of structure on the nutritional impact of food is beginning to be understood both in terms of delivering nutrients to the body,1 and also in terms of its potential to exert protective effects against chronic diseases.2 In this article we will illustrate these areas using two examples of the AFM work bei...

Experimental hematogenous Candida albicans endophthalmitis: electron microscopy.

As part of a study of pathogenesis of experimental hematogenous Candida albicans endophthalmitis in New Zealand White female rabbits, lesions of the disease were examined electron microscopically 4 to 16 days after intravenous inoculation with a patient's strain of C. albicans. Each lesion consisted of an inflammatory retinovitreal nodule and a surrounding zone of infiltrated chorioretina. The ...
