    Notes: Abstract  Near-surface sediment geoacoustic and physical properties were measured from a variety of unconsolidated carbonate sediments in the Lower Florida Keys. Surficial values of compressional and shear speed correlate with sediment physical properties and near-surface acoustic reflectivity. Highest speeds (shear 125–150 m s-1; compressional 1670–1725 m s-1) are from sandy sediments near Rebecca Shoal and lowest speeds (shear 40–65 m s-1; compressional 1520–1570 m s-1) are found in soft, silty sediments which collect in sediment ponds in the Southeast Channel of the Dry Tortugas. High compressional wave attenuation is attributed to scattering of acoustic waves from heterogeneity caused by accumulation of abundant shell material and other impedance discontinuities rather than high intrinsic attenuation. Compared to siliciclastic sediments, carbonate sediment shear wave speed is high for comparable values of sediment physical properties. Sediment fabric, rather than changes due to the effects of biogeochemical processes, is responsible for these differences.

    Notes: A rapid ELISA was developed for the detection of specific IgG against Micropolyspora faeni and Thermoactinomyces vulgaris and compared with counterimmunoelectrophoresis (CIE) in twenty-seven patients with suspected farmer's lung disease (FLD). Seventeen patients had precipitins to M. faeni or T. vulgaris or both, and ten had no precipitins. The optimum conditions for each step in the ELISA were determined: pre-equilibration of reagents at 370C and vigorous agitation during incubation enabled the total test time required for the procedure to he reduced to 4 hr. A serum dilution of 10-fold produced good differentiation between CIE-positive and -negative sera. Little correlation was seen between CIE and ELISA for either M. faeni or T. vulgaris antigens in tests with sera from patients with precipitins: high readings were often recorded in ELISA where no precipitins had been detected with the same antigen. Positive- negative discrimination of unknown sera in ELISA was achieved through the inclusion of CIE-positive and -negative reference sera in each test run. Thirteen CIE-positive sera were classed as positive in ELISA with the M. faeni antigen while eight of thirteen CIE-positive sera were positive in ELISA with the T. vulgaris antigen. For both antigens, four CIE-negative sera were recorded as positive in ELISA.

    Notes: The association (adherence) between human corneocytes and arthroconidia of Trichophyton mentagrophytes strains 121 and 126, and T. interdigitale strain 4 was studied in vitro. Adherence of arthroconidia to corneocytes from either the palm and sole occurred and increased with time up to 6 h, by which time germination of arthroconidia had started. Significant differences were seen between the T. mentagrophytes strains and T. interdigitale in their adherence to corneocytes from the palm. When adherence values for plantar corneocytes were compared, significant differences were found between T. mentagrophytes had T. interdigitale. Not all corneocytes from either site had adherent arthroconidia, although there was a time-dependent increase in the numbers of corneocytes with adherent fungal cells. By scanning and transmission electron microscopy it was seen that there was a loose association between arthroconidia and corneocytes with no apparent damage to the corneocytes membrane. Adherence of germlings of T. interdigitale to corneocytes from the palm appeared to be mediated by germling outer cell wall fibrils. Hyphal branches and secondary germlings were observed to enhance the attachment of the parent hypha to adjacent corneocytes.

    Benthic boundary layer processes in the Lower Florida Keys (1997)

    Notes: Abstract  This special issue of Geo-Marine Letters, “Benthic Boundary Layer Processes in the Lower Florida Keys,” includes 12 papers that present preliminary results from the Key West Campaign. The Dry Tortugas and Marquesas Keys test sites were selected by a group of 115 scientists and technicians to study benthic boundary layer processes in a carbonate environment controlled by bioturbation and biogeochemical processes. Major activities included remote sediment classification; high-frequency acoustic scattering experiments; sediment sampling for radiological, geotechnical, biological, biogeochemical, physical, and geoacoustic studies; and hydrodynamic studies using an instrumented tetrapod. All these data are being used to improve our understanding of the effects of environmental processes on sediment structure and behavior.

    Small-scale fluctuations in acoustic and physical properties in surficial carbonate sediments and their relationship to bioturbation (1997)

    Notes: Abstract  Measurements of physical and acoustic properties within the top 40 cm of sediment indicate that there are three classes of parameter variability relevant to acoustic bottom scattering at the Marquesas Keys and Dry Tortugas sites. The three classes of variability, spatially and temporally different in terms of scale, are generated by biological and physical processes acting on sediments. Interplay of bioturbation, trawling and storm events create fine laminations of sand–silt–clay and high gravel-size mollusk shell content at the Marquesas Keys site; the predominance of biological processes creates strong surficial gradients and lateral variability in sediment properties at the Dry Tortugas site.

    Notes: Abstract This special issue ofGeo-Marine Letters “Benthic Boundary Layer Processes in Coastal Environments” includes 20 papers devoted to results of recent near-shore experiments supported by the Coastal Benthic Boundary Layer (CBBL) program. Experiments were conducted in gas-rich muddy sediments of Eckernförde Bay of the Baltic Sea and on relict sandy sediments of the West Florida Sand Sheet. In this introductory paper we present scientific justification for experiments and summarize preliminary results.

    In situ and laboratory geoacoustic measurements in soft mud and hard-packed sand sediments: Implications for high-frequency acoustic propagation and scattering (1996)

    Notes: Abstract Near-surface sediment geoacoustic and physical properties were measured in gas-rich, muddy sediments of Eckernförde Bay, Baltic Sea, and in hard-packed, sandy sediments of the northeastern Gulf of Mexico. Values of compressional and shear wave velocity are much lower in muddy compared to sandy sediments. The spatial and temporal variability of sediment physical and geoacoustic properties and, as a consequence, the scattering and propagation of high-frequency acoustic waves are primarily related to the presence and absence of free methane gas bubbles at the muddy site and to the abundance and distribution of shell material on sandy sediments.

    Effect of cilofungin on phagocytosis and intracellular killing ofCandida albicans by human neutrophils (1992)

    Notes: Abstract The effect of a beta glucan synthase inhibitor, cilofungin, amphotericin B and 5-fluorocytosine on opsonization, phagocytosis and intracellular killing ofCandida albicans blastospores by glass-adherent human neutrophils was determined by microscopy and dye exclusion staining. Pretreatment of blastospores for 2, 4, 6 and 18 h with 1.25 mg/l cilofungin resulted in 24–28 % of neutrophils ingesting compared to 24 % with no drug present. There was no significant difference in the phagocytic index with increased incubation time. Percentage ingestion and phagocytic index values were not significantly different when blastospores were pretreated for 2 h in the presence of 3, 7. 15, 31 and 62 mg/l cilofungin. Comparable concentrations of amphotericin B and 5-fluorocytosine gave similar results. In the absence of cilofungin, intracellular killing after 2 h was 54 %. In the presence of 1 and 10 mg/l cilofungin, 85–90 % of intracellular blastospores were killed. Therapeutic levels of amphotericin B or 5-fluorocytosine did not enhance intracellular killing. These data demonstrate the potentiation of intracellular killing ofCandida albicans by neutrophils in the presence of cilofungin.
