    Notes: The suitability of VLF ground surveys in the investigation of shallow two-dimensional structures is analyzed. For such structures the polar formalism is derived, necessary in practice since the transmitters are generally not in the structural strike or profile. A simple vertical dike is considered to demonstrate the striking anisotropy which can be expected over such a structure, in particular the high apparent resistivity along the direction of a well-conducting dike and the low resistivity across it. The theory is then confronted with the practical example of an asymmetrical vertical dike resulting from a strike-slip fault. Modelling of the survey results is very successful and yields good confirmation of the polar behaviour. VLF ground surveys thus provide a quick and powerful tool for the study of geological accidents within about 100 m of the surface.

    Glycosaminoglycans of Rat Cerebellum: II. A Developmental Study (1985)

    Notes: Abstract: Total and individual glycosaminoglycans (GAGs) were determined in rat cerebellum in tissue explants at various postnatal ages. The major constituents of GAGs were chondroitin sulfate (CS), hyaluronic acid (HA), and heparan sulfate (HS). Dermatan sulfate (DS) and keratan sulfate (KS) could not be detected and therefore each amounts to 〈5% of all GAGs at all ages studied. HA was the prominent GAG during postnatal development and only a minor constituent at adult ages, whereas CS was the predominant GAG in adulthood. HS remained relatively constant throughout development. The incorporation of [3H]glucosamine into individual GAGs was highest for HS at postnatal day 6, whereas HA showed intermediate and CS the lowest levels of incorporation during the first postnatal week. All major GAGs showed the lowest incorporation values at adult ages.

    Notes: Abstract: Isolated glycosaminoglycans (GAGs) were quantified biochemically in the cerebella of 6-day-old rats. 14C-Labeled hyaluronic acid (HA) and chondroitin-4-sulfate (C-4-S), added prior to isolation of GAGs from tissue, served as internal standards to allow correction for unknown losses during the purification procedure and exact quantification of GAGs in the intact tissue. Three main constituents—HA, chondroitin sulfate (CS), and heparan sulfate (HS)—were found at concentrations of 1.82, 1.52, and 0.76 μg/mg protein amounting to 44%, 37%, and 19% of the total GAG fraction, respectively. Incorporation of [3H]glucosamine precursor into GAGs was higher for HS (56% of incorporated precursor) and lower for HA (29%) and CS (15%). The specific activities of individual GAGs were 64.7 nCi/μg for HS, 14.2 for HA, and 8.3 for CS.

    SOME REMARKS ON THE BEHAVIOR OF THE MAGNETOTELLURIC PHASE (1985)

    Notes: The magnetotelluric phase in the medium of incidence over a good conductor varies from its value at the conductor surface, usually close to 45°, to the characteristic standing-wave phaseshift of 90° over a distance of a few conductor skin-depths, much shorter than the vacuum wavelength at the frequencies considered. Over the top of a graben or at the surface of a two-layer structure the basement can be looked upon as the matrix. If the graben or the overburden is a better conductor it will carry an extra current density in phase with the electric field, thus giving rise to an additional magnetic field also in phase with the electric field. This drives the argument of the surface impedance toward smaller values. For a more resistive graben or overburden the current is depressed, corresponding to a reduction of the surface magnetic field by an amount in phase with the electric field. This effect drives the phase of the impedance to values above the characteristic 45° of a uniform conductor.

    MULTIFOCAL FIBROSCLEROSIS: CUTANEOUS ASSOCIATIONS (1986)

    Notes: There is a group of disorders characterized by simultaneous and progressive fibrosis of several discrete regions of the body. This disease complex, “multifocal fibrosclerosis”, most commonly involves the retroperitoneal and mediastinal compartments and may be accompanied by cutaneous lesions. In most cases the aetiology is unknown but there is good evidence, supported by the patient we describe, for a vasculitic origin in a significant proportion of patients.We report a case of multifocal fibrosclerosis associated with cutaneous lesions. These included livedo reticularis and recurrent, painful nodules and pustules on the legs and feet, which progressed to chronic ulceration. Histologically there was evidence of an underlying necrotising vasculitis.A review of the cutaneous changes that have been reported in association with multifocal fibrosclerosis allows speculation regarding the aetiology of the disease process.

    Natural distribution of 5 bacteria associated with periodontal disease (1993)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of clinical periodontology 20 (1993), S. 0

    Topics: Medicine
    Notes: Abstract The purpose of this study was to determine the prevalence and distribution of 5 bacterial pathogens in subgingival plaque, their relationship with each other and probing depth. Plaque was collected from 6905 sites in 938 subjects. A bacterial concentration fluorescence immunoassay and bacterial specific monoclonal antibodies were used to determine the presence and level of P. gingivalis (Pg), A. actinomycetemcomitans (Aa), P. intermedia (Pi), E. carrodens (Ec) and F. nucleatum (Fn) in each plaque sample. The prevalence in subjects was lowest for Pg (32%) and highest for Ec (49%). The site-based frequency distribution of these bacterial species ranged from 10.3% for Pg to 18.7% for Ec. Pi and Ec were the bacterial combination most often found together in a subject (27.2%). While 64.0% of the sites were without any of the 5 bacterial species evaluated, 20.2% had only 1 of the 5 bacterial species evaluated. The remaining 15.8% of sites had at least 2 bacteria species present. There was a general linear association of the detection level of bacterial species and probing depth. The odds ratios were 3.9 (Pg). 3.0 (Aa), 4.0 (Pi). 2.7 (Ec) and 2.8 (Fn) of finding high levels of these bacterial pathogens at 〉 5 mm probing depth (p≤ 0.01). Mean probing depth at molar sites without a specific bacteria was greater (p≤ 0.01) in subjects wish a specific bacterium compared to molar sites in subjects without the bacteria. The observation that these 5 bacterial species frequently inhabit the subgingival environment, yet are not associated with advanced disease, suggest that a susceptible host is required, in addition to a “pathogenic bacteria”, before disease progression may occur.

    Neutrophil elastase in crevicular fluid: comparison of a middle-aged general population with healthy and periodontitis groups (1995)

    Notes: Abstract Neutrophil elastase (NE) was measured in crevicular fluid (GCF) collected from 3 subject groups. GCF was harvested at a single visit of subjects with periodontal health (n=21) and with periodontitis (n=28). Samples were obtained from 132 middle-aged, middle-class health conscious patients of a health maintenance organization (HMO) at baseline and 1 year later. GCF NE was higher in periodontitis than in health. Mean GCF NE of HMO subjects was much closer to health than to periodontitis. Few members of the HMO population had enzyme levels typical of periodontitis. Subjects and sites of the HMO population were segregated into 3 categories based on enzyme levels of the healthy and periodontitis subjects. Most HMO subjects and sites were in the activity category corresponding to healthy subjects. Only a small portion were in the activity category common in periodontitis. Enzyme levels in the highest activity category at both samplings were infrequent. High enzyme levels in the HMO population were not associated with attachment loss. Thus, assay of GCF NB provided little evidence of disease in a middle-aged, middle-class health conscious general population. This finding confirms an analysis of epidemiological surveys which concluded that a population such as studied here would not benefit from periodontal diagnostic testing.
