    Notes: Summary The neuropathology in three cases of glutaric acidaemia type 1 is presented. All three showed extensive neuronal loss in the caudate nucleus and the putamen, with only small numbers of large neurons surviving. The globus pallidus showed moderate shrinkage and gliosis but no conspicous decreases in neurons. Severe spongiform change was seen in many regions, involving predominantly white matter. These features are very similar to some cases described previously in familial striatal degeneration in childhood, but are different from other cases. If found in a brain at autopsy, they should lead to studies to diagnose glutaric acidaemia type 1 restrospectively, so that accurate genetic counselling and prenatal diagnosis in future pregnancies can be offered.

    Treatment of infantile phytanic acid storage disease: clinical, biochemical and ultrastructural findings in two children treated for 2 years (1988)

    Notes: Abstract Two patients with infantile phytanic acid storage disease (infantile Refsum disease), one of whom showed the presence of morphologically normal peroxisomes in a liver biopsy, were treated with a low phytanic acid diet for more than 2 years and the effects of treatment on certain clinical, biochemical and ultrastructural parameters were examined. Both patients showed evidence of either an improvement or stabilisation in their clinical condition. Plasma phytanic acid levels decreased to near normal values in approximately 6 weeks after the introduction of the diet; plasma pipecolic acid also declined markedly but the decrease was not so rapid and its level remained abnormal. C26∶C22 fatty acid ratios decreased very slowly and even after 2 years the values remained grossly abnormal. Despite the marked reduction of phytanic acid in the liver, there was an increase in the C26∶C22 fatty acid ratios and this appeared to be paralleled by an increase in inclusion bodies. Our data suggest that some patients with the infantile form of Refsum disease may show some clinical benefit from dietary management and this is reflected biochemically by decreases in the plasma levels of phytanic acid and pipecolic acid.

    Notes: This paper describes a system for the summarization of multiple text-only news-like documents. We address two main issues: clustering of documents in order to find the main topics that should be mentioned in the multidocument summary and organization of the information in order to create a summary that presents the information in a logical way and is easy to read. The system is based on a single-document summarizer that uses text-extraction.

    Ultrastructural features of the dental follicle associated with formation of the tooth eruption pathway in the dog (1985)

    Notes: The dental follicle is a loose connective tissue layer that surrounds the developing and erupting tooth. The follicle is necessary for tooth eruption in dogs and specific cellular changes occur in the follicle at the onset of tooth eruption, in particular, within the coronal region of the follicle next to areas of subsequent bone resorption there is an increase in mononuclear cells which have the ultrastructure features of monocytes and contain specific granules characteristic of preosteoclasts. The follicle has an extensive microvasculature and monocytes are often seen adjacent to capillaries and venules. Monocytes increase in number in direct proportion to the increase in osteoclasts that form the eruption pathway and decrease in number as soon as this activity is completed. It is postulated that monocytes enter the follicle from the microvasculature and then migrate to the walls of the bony crypt to participate in the formation of the eruption pathway.

    On an aspect of matched filters in continuous and discrete time (1983)

    Notes: Abstract In this paper we present an approach for improving the output signal-to-noise power ratio of a discrete-time matched filter by employing a continuous-time filter, even though the continuous-time signal input is imperfectly known. It is shown that is it possible to design a continuous-time filter which is robust to inexact knowledge of the signal input; moreover, the robustness property does not severely compromise performance. In fact, it is shown that the resulting filter possesses an output signal-to-noise power ratio which upper bounds that of the discrete-time filter.

    Culture and characterization of dental follicle cells from rat molars (1992)

    Notes: Summary Because the dental follicle is necessary for the eruption of teeth of limited eruption, it was the objective of this study to determine if the cells of the follicle could be cultured in vitro. To achieve this, dental follicles and associated enamel organs were dissected from the first and second mandibular molars of 6–7-day-old rats (secretory stage of amelogenesis), and then cultured in a medium that promotes fibroblast growth — the predominant cell type of the dental follicle. The cultured cells grew to confluency and were kept through 3 passages before experimentation. The cultured cells were fibroblastic in shape, elongate with processes, and transmission electron microscopy revealed that they contained an abundant rough endoplasmic reticulum, but did not form desmosomes. Immunofluorescent staining for anti-vimentin showed that all the cells stained and electron-microscopic immunogold labeling indicated that the antibody was associated with intermediate filaments. As revealed by SDS-polyacrylamide gel electrophoresis and Western blotting, the cultured cells synthesized and secreted the extracellular matrix molecules fibronectin and procollagens. Subsequent immunofluorescence staining of permeabilized and non-permeabilized cells confirmed the presence of fibronectin and type I collagen both intra- and extracellularly. Thus, based on all the above characteristics, the cultured cells appeared to be fibroblasts derived from the dental follicle, although a few of the fibroblasts may be derived from undifferentiated mesenchymal cells interposed between the alveolar bone and follicle. Experiments now can be conducted to determine how these cultured cells respond directly to growth factors that alter the rates of tooth eruption.

    Effects of epidermal growth factor (EGF) and colony-stimulating factor-1 (CSF-1) on expression of c-fos in rat mandibular molars: implications for tooth eruption (1996)

    Notes: Abstract. The c-fos gene is expressed in the dental follicle of the first mandibular molar of rats. Molecules that accelerate tooth eruption, epidermal growth factor (EGF) and colony-stimulating factor-1 (CSF-1), enhance the expression of the c-fos gene in vitro in both a time- and concentration-dependent manner. In vivo, EGF enhances c-fos expression in the follicle from day 0–7 postnatally, but by day 9 the follicle is refractory to this stimulus. Immunostaining reveals that the c-fos gene is translated in the cultured dental follicle cells, with staining seen in the nucleus and the perinuclear region of the cytoplasm. In vivo, immunostaining for c-fos is prominent in the dental follicle early postnatally, with little or no staining seen in the stellate reticulum and dental pulp. By day 10 postnatally, staining for c-fos is greatly reduced in the dental follicle. Thus, the presence of c-fos early postnatally in the tissue required for eruption, the dental follicle, as well as the enhancement of c-fos gene expression in the follicle by EGF or CSF-1, suggests that c-fos plays a role in tooth eruption. That role may be either to promote differentiation of mononuclear cells into osteoclasts needed for eruption or to recruit the mononuclear cells into the follicle.
