A Light Microscopical Investigation And

113 randomly selected frustules of Cyclotella taxa, taken from the plankton of four lakes, have been investigated with respect to variation between the two thecae of each frustule and also variation within and between populations occorring in the different lakes. Multivariate statistical analyses of phenetic similarity of the 226 thecae were based on a data matrix recording the status of 11 cha...

Electron microscopical findings in hypertrophied human ventricle.

The, normal ultrastructure of the human myocardium is fairly well documented (Porter and Bonneville, 1963; Stenger and Spiro, 1961; Burdette and Ashford, 1963; Lannigan and Zaki, 1966) and some of the prominent subcellular changes have also been described (Burgos and Rodriguez-Echandta, 1966; Alexander, 1967). We should like here to present the ultrastructural features observed in hypertrophied...

Electron microscopical investigation of asbestos fibers

Examination of asbestos fibers by electron microscopical techniques enables the observer to distinguish among the fiber types by morphological and structural characteristics. Chrysotile asbestos fibers are composed of bundles of fibrils. Fibers are often curvilinear with splayed ends. Individual fibrils consist of a central capillary defined by an electron dense crystalline wall. With increasin...
