(Uploaded by Plazi for the Bat Literature Project) A juvenile grey‐headed flying fox (GHFF) ( Pteropus poliocephalus ) presented to the Australia Zoo Wildlife Hospital after a wildlife carer found the animal hanging on the outside of an aviary. On presentation, the animal was emaciated and moribund with disseminated, multifocal, depigmented and proliferative lesions on the wing membranes and skin of the neck. Histopathology revealed multiple, well‐circumscribed proliferative epidermal lesions with intracytoplasmic inclusion bodies. A poxvirus was identified via transmission electron microscopy

Abstract:

This study investigates the morphological aspects of larval development in Maylandia estherae, an endemic cichlid species from Lake Malawi. Larvae obtained from mature broodstock were sampled daily from hatching until the juvenile stage, and their morphological development was observed under a microscope. Important morphological features such as mouth opening, exogenous feeding, free swimming, yolk sac, and pigmentation were observed and photographed. The findings indicate that M. estherae larvae reached the juvenile stage within approximately 20-25 days. Throughout larval development, it was

The present study aimed to develop a qualitative understanding of the morphological and reproductive differences across the latitudinal gradient of B. villosa.

Summary Loblolly pine, separated into mature and juvenile portions, was refined at various pressures (4, 8 and 12 bar). Fiber surfaces were investigated using a Scanning Electron Microscope (SEM) and an Atomic Force Microscope (AFM). Refiner pressure had a significant effect on the fiber surfaces. SEM images showed an apparent increase in surface roughness with increased refiner pressure. This was shown quantitatively with data from the AFM that was analyzed using 5, 2.5 and 1.25 μm scan sizes. A scan size of 2.5 μm was found to be the most informative in terms of quantifying the effect of the

The morphology of balanomorph barnacles during metamorphosis from the cyprid larval stage to the juvenile has been examined by light microscopy and scanning electron microscopy (SEM). The free-swimming cyprid attaches to a substrate, rotates 90° in the vertical plane, molts, and assumes the adult shape. The resulting metamorph is clad in soft cuticle and has an adult-like appearance with a mantle cavity, thorax with cirri, and incipient shell plates. At some time during the development from cyprid to juvenile, the barnacle begins to mineralize its shell, but it is not known whether calcificati

A fundamental problem in conventional light microscopy has long been the lack of image quality brought about by the use of sections which are thicker than the depth of field (DOF) of the microscope. These sections are used because “paraffin & steel” microtomy techniques preclude sections thinner than a few microns. The transmission electron microscope, however, requires section thicknesses of less than a micron. This requirement has resulted in the development of “epoxy & glass” microtomy techniques, and the ability to cut sections as thin as a few hundred Ångstroms. These thin section

Abstract:

The shape of cells during interphase in sparse cultures often resembles that of fried eggs. XTH-2 cells, which have been derived from tadpole heart endothelia, provide a typical example of this type of shape. To understand the physical basis of this shape, the cytoskeleton of these cells has been investigated in detail. Subcellular elasticity data have been achieved by scanning acoustic microscopy (SAM). Their changes were observed during treatment of the cells with microtubule-disrupting agents (colcemid and low temperature), and shape generation in giant cells produced by electro-fusion was

Abstract:

The Atomic Force Microscope (AFM) has been used to reliably measure lamellar thickness in semi-crystalline polymers, and to distinguish phases within blends of these polymers.Traditionally, lamellar thicknesses of semi-crystalline polymers have been determined by (1) measuring structures directly from TEM micrographs or (2) using small angle X-ray scattering (SAXS) spectra. In the first case, the sample must either be etched and replicated, or stained with heavy metals or chlorosulfonic acid to reveal the lamellar structures. Good SAXS measurements require access to a synchrotron, or rotating

Abstract:

Recent papers have discussed some of the difficulties in determining the structure of very small (<10Å) metal particles using electron microscopy. One of the ideas in the literature is that electron diffraction could provide structural information even under conditions where imaging is difficult. The purpose of the work reported here is to demonstrate that one can use electron diffraction techniques to obtain structural information about small metal particles, in this case 5Å osmium particles on a carbon film.

Abstract:

The microscopic and fragile nature of the protozoans is the major barrier to their study. The most traditional taxonomic literature on protozoans is illustrated with stained specimens, which sometimes do not resemble the living cells. These artifacts are satisfactory for taxonomy purposes, but not for ecological analysis. Staining methods cause the cells to shrink and also cell wall disruption. This work describes a combination of the Utermohl method and a new concentration device plus video microscopy for analysing living protozoans. The procedure seems to be an accurate and reliable way to a

Abstract:

The ultimate goal of high resolution electron microscopy is to determine quantitatively the atomic structure of an object. In this respect the electron microscope can be considered as an information channel that carries this information from the object to the observer. High resolution images are then to be considered as data planes from which the structural information has to be extracted.However this structural information is usually hidden in the images and cannot easily be assessed. Therefore, a quantitative approach is required in which all steps in the imaging process are taken into accou

A catalyst that was observed to contain only Pt-rich alloy particles, performed better than catalysts which contained Rh-rich alloy particles or a mixture of Pt-rich and Rh-rich particles. The reaction data suggested that Rh may have segregated to the surface of the individual Pt-rich alloy particles. This observation is consist

The studies performed in several laboratories have demonstrated the potential of applying this technique for imaging the internal structures of intact cells. However, it is currently used mainly on synchrotrons with restricted access. Moreover, the operation of these instruments and the associated sample-preparation protocols require interdisciplinary and highly specialized personnel, limiting their wide application in practice.

Abstract:

The application of transmission electron microscopy (TEM) for the research on biological and inorganic structures is restricted by the radiation sensitivity of the specimens and the deviations from the optimal setting of the TEM parameters. The three most important optical parameters that require extensive fine tuning are the defocus, astigmatism and beam tilt misalignment. Autotuning, i.e. automatic optimization of these three parameters, can help to optimize microscope settings using a minimum amount of electron irradiation.Until recently, the practical applications of the autotuning methods
