    A new type of polytetrafluoroethylene prosthesis (Mycro Mesh): an experimental study (1996)
    Springer
    Journal of materials science 7 (1996), S. 475-478

    Notes: Abstract Comparisons were made of the tissue response to the implantation of two different polytetrafluoroethylene prostheses: Soft Tissue Patch (STP) and Mycro Mesh (MM). A 7 × 5 cm prosthesis of STP (n=12) or MM (n=12) was implanted into a defect of the same size (involving all layers except skin) created in the anterior abdominal wall in 24 New Zealand rabbits. The prostheses were anchored to the recipient tissue, in direct contact with the intestinal loops and connective tissue. After 14, 30, 60 and 90 days, groups of six implants were studied macroscopically and samples were taken to be processed by light microscopy, scanning electron microscopy (SEM), immunohistochemical studies and tensiometry. All animals were valid for the study. In three cases STP implants presented very loose adhesions in the peripheral zones corresponding to the sutures. They were also observed on three MM implants, in the area of the perforations. Light and scanning microscopy revealed the formation of a capsule of scar tissue surrounding both types of prosthesis. At day 90, bridges of connective tissue had formed in the perforated areas of MM. Good vascularization was established in the areas of recipient tissue corresponding to both implants. The macrophage reaction to both biomaterials was maximal at 14 days, after which it progressively decreased until day 90. Tensile testing revealed no significant differences between the two biomaterials. It is concluded that (a) behaviour in the peritoneal interface is similar in the two prostheses, (b) both biomaterials become encapsulated rather than integrated into the recipient tissue, (c) the foreign body reaction does not determine the success or failure of the implants, (d) The perforations of the MM prosthesis do not increase its resistance to stress, or at least not after 90 days of implantation into rabbit abdominal wall.

    Validation of a high-performance chromatographic method for determination of cefotaxime in biological samples (1999)
    Springer
    Fresenius' journal of analytical chemistry 363 (1999), S. 289-293 
    Details
    ISSN: 1432-1130
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract An analytical method for detecting and quantifying cefotaxime in plasma and several tissues is described. The method was developed and validated using plasma and tissues of rats. The samples were analyzed by reversed phase liquid chromatography (HPLC) with UV detection (254 nm). Calibration graphs showed a linear correlation (r 〉 0.999) over the concentration ranges of 0.5–200 μg/mL and 1.25–25 μg/g for plasma and tissues, respectively. The recovery of cefotaxime from plasma standards prepared at the concentrations of 25 μg/mL and 100 μg/mL was 98.5 ± 3.5% and 101.8 ± 2.2%, respectively. The recovery of cefotaxime from tissue standards of liver, fat and muscle, prepared at the concentration of 10 μg/g was: 89.8 ± 1.2% (liver), 103.9 ± 6.5% (fat) and 97.8 ± 2.1% (muscle). The detection (LOD) and quantitation (LOQ) limits for plasma samples were established at 0.11 μg/mL and 0.49 μg/mL, respectively. The values of these limits for tissues samples were approximately 2.5 times higher: 0.3 μg/g (LOD) and 1.25 μg/g (LOQ). For plasma samples, the deviation of the observed concentration from the nominal concentration was less than 5% and the coefficient of variation for within-day and between-day assays was less than 6% and 12%, respectively. The method was used in a pharmacokinetic study of cefotaxime in the rat and the mean values of the pharmacokinetic parameters are given.

    General change of variable formulas for semimartingales in one and finite dimensions (1993)
    Springer

    Notes: Summary A general one dimensional change of variables formula is established for continuous semimartingales which extends the famous Meyer-Tanaka formula. The inspiration comes from an application arising in stochastic finance theory. For functions mapping ℝ n to ℝ, a general change of variables formula is established for arbitrary semimartingales, where the usualC 2 hypothesis is relaxed.

    Partial trisomy for the long arm of chromosome 7. Case report and review (1982)

    Notes: Summary We reviewed partial trisomy of the long arm of chromosome 7 after a new case was brought to our attention. The clinical differences between the various types of trisomies 7q were evaluated by statistical analysis, and three groups were defined. These groups correspond to the segments q22 or q21»q31, q31»qter, and q32»qter, and would seem to represent three different syndromes, of which one is more serious than the other two.

    On the finding of a mass occurrence of Serpula narconensis Baird, 1885 (Polychaeta, Serpulidae) in South Georgia (Antarctica) (1999)

    Notes: Abstract A new “reef ” of the serpulid polychaete Serpula narconensis Baird, 1885 is reported from the South Georgia Island shelf. This particular mass occurrence is the second serpulid “reef” reported in the Antarctic region. Its location, at 91- to 105-m depth, is very different from those serpulid reefs previously reported, usually sited at intertidal zone or at low depth, and this may be one of the largest, if not the largest, serpulid reef in the world.

    Notes: Abstract. We study the asymptotic behaviour of the transition density of a Brownian motion in ?, killed at ∂?, where ? c is a compact non polar set. Our main result concern dimension d = 2, where we show that the transition density p ? t (x, y) behaves, for large t, as u(x)u(y)(t(log t)2)−1 for x, y∈?, where u is the unique positive harmonic function vanishing on (∂?) r , such that u(x) ∼ log ∣x∣.

    Notes: Abstract The Spanish cruise “Bentart 94” was the first of two devoted to the study of the benthic marine fauna off Livingston and Deception Islands, South Shetland Islands, Antarctica. In this paper, the taxonomic results of the examination of the “errant” families of the polychaetes collected during that cruise are presented. A total of 834 specimens have been examined, belonging to 34 species of 31 genera and 11 families. A new species, Micronereis anaramosae, is described, and Eusyllis kerguelensis McIntosh is referred to the genus Pionosyllis. The specimens were found in 109 samples of muddy sand, mud, stones, rocks, gravel, and mixed sediments, by scuba diving, Van Veen grab, rock trawl and anchor dredge.

    Quantitative analysis of macrobenthic soft-bottom assemblages in South Shetland waters (Antarctica) (1997)
    Springer
    Polar biology 17 (1997), S. 393-400 
    Details
    ISSN: 1432-2056
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Macrobenthic assemblages were investigated at 26 stations located around Livingston Island, Deception Island and the Bransfield Strait at depths ranging from 42 to 671 m. Representatives of 30 major taxa were found. The maximal density was 5,260 specimens·m−2 at Livingston Island; the mean abundance per station ranged from 160 to 4,380 specimens·m−2. The total biomass of the macrozoobenthos declined with depth, with mean values of 3,201 g·m−2 at shallower depths (〈 100 m) and 210 g·m−2 further down (〉 100 m). After multivariate analysis (cluster analysis, MDS) based on Bray-Curtis dissimilarities, most stations could be assigned to one of three groups on the basis of distinct biomass differences between sites. The first cluster with a rich Ascidiacea biomass is common on shallower bottoms. The second, with Ophiuroidea as a characteristic group, is common on deeper bottoms. The absence of an ‘indicator’ taxon is characteristic of the remaining cluster of those stations with the lowest biomass values. No significant correlations were detected between macrobenthic biomass and any sediment parameters measured, probably because part of the benthos (i.e. the epifauna) could be better explained by the coupling with a highly productive water column. The role of the epi-infauna sensu Gallardo as the main factor structuring benthic assemblages in the investigated area is discussed.
