    Transjugular liver biopsy: modified Ross transseptal needle versus Quick-core biopsy needle (2000)

    Notes: Abstract Background: We evaluated the differences in sample adequacy and safety between a transseptal needle and Quick-core biopsy needle for transjugular liver biopsy. Methods: Eighteen consecutive patients who had a bleeding diatheses and/or ascites underwent transjugular liver biopsy using a transseptal needle (11 patients) and Quick-core biopsy needle (seven patients). The length of the specimens was measured before fixation. A pathologist reviewed histologic slides for sample adequacy and pathologic diagnoses. Clinical records were reviewed for complication. Results: In all patients, liver biopsy was successful. A total of 45 specimens were obtained, with an average of 2.5 passes per patient. The length of specimen was significantly longer with the Quick-core biopsy needle than with the transseptal needle (p 〈 0.05). Biopsied tissue was fragmented in 17 of 25 specimens with the transseptal needle but not fragmented in any specimen with the Quick-core biopsy needle. All specimens were determined to be adequate except one with the transseptal needle. There was no early or delayed complication in any patient. Conclusion: Transjugular liver biopsy is a safe and effective procedure without any significant difference in complication and adequacy when using a transseptal needle or Quick-core biopsy needle. Larger specimens can be obtained without tissue fragmentation with the Quick-core biopsy needle.

    Expression of bvgAS of Bordetella pertussis represses flagellar biosynthesis of Escherichia coli (1999)

    Notes: Abstract BvgAS is a two-component system of Bordetella pertussis involved in the reciprocal regulation of the virulence genes and the flagellar biosynthesis. In this study, we found that expression of bvgAS in Escherichia coli also results in reduced motility. The repression was relieved by the addition of known chemical modulators of BvgAS such as MgSO4 and nicotinic acid, indicating that functional BvgAS proteins are required for the negative control of E. coli motility. In addition, BvgAS repressed the transcription of the flhDC master operon of E. coli, which consequently caused non-flagellation on the cell surface. However, expression of BvgAS had no effect on stress-resistant motile mutants of E. coli. These data suggest that E. coli may have BvgA-like protein(s) involved in the regulatory interactions between the stress response and the flagellar biosynthesis.

    Notes: : :The effects of ozone gas concentration (2 to 8 mg/l), relative humidity (RH) (60 to 90%), and treatment time (10 to 40 min) on inactivation of E. coli O157:H7 on green peppers were studied using response surface methodology. A 3-factor Box-Behnken experimental plan was designed and microbial log reduction was measured as a response. The statistical analysis of developed predictive model suggested that ozone gas concentration, RH, and treatment time all significantly (P 〈 0.01) increased the rate of log reduction of E. coli O157:H7. Among the 3 factors, the effect of ozone gas concentration on bacterial inactivation was the greatest, while the effect of RH was the least. The interaction between ozone gas concentration and RH exhibited a significant and synergistic effect (P 〈 0.05).

    GAS CHROMATOGRAPHIC CHARACTERIZATION OF OREGANO AND OTHER SELECTED SPICES OF THE LABIATE FAMILY (1979)

    Notes: The Labiate family includes many common spices, some so similar that differentiation can be difficult. Available literature on the individual spices does not take into consideration the lot-to-lot variances and does not aid much in differentiation. All major Labiate spices procured from various areas during 1971–1978 were ground and steam-distilled in the laboratory. Gas chromatographic profiles show no differences in qualitative composition of monoterpenes but only in their quantitative distribution. Correlation and multiple correlation coefficients suggest further similar chemistry of compound formation throughout the Labiate family during the life cycle of the plant. Differentiation between Greek and Mexican oregano is demonstrated by the use of linear discriminant function.

    GAS CHROMATOGRAPHIC CHARACTERIZATION OF SAGES OF VARIOUS GEOGRAPHIC ORIGINS (1979)

    Notes: Many studies published to date do not include a comprehensive comparison among the various types of sage available in commerce. Sages procured from Yugoslavia, Albania, Greece, Turkey and Italy during 1971 - 1977 were ground and steam-distilled in the laboratory. Gas chromatographic profiles obtained on the resulting volatile oils suggest that the Greek, Turkish and Italian are strikingly similar and are believed to be of Salvia triloba L., and that though both the Yugoslavian and Albanian are of S. offcinalis L., they display substantial differences. It is also shown by the use of linear discriminant function that the Yugoslavian sage may be subclassified into those grown in the Dalmatia region and those grown elsewhere in Yugoslavia.

    COMBINED EFFECT OF HEAT AND ALKALI IN STERILIZING SUGARCANE BAGASSE (1971)

    Notes: — Bacterial spores contained in sugarcane bagasse were subjected to various combinations of heat exposure and alkali concentration and the rate of destruction determined for each set of conditions. A series of survival, thermal death time and alkaline destruction curves revealed a different mode of death by heat exposure than alkali treatment. Addition of alkali into the heating menstruum caused the death rates of bacterial spores to be much greater than with heat alone at a given temperature. Exposure of the spores to a temperature of 75°C for 130 min was required to reduce the spore population by 90% with heat treatment alone. Incorporation of a 1% NaOH solution into the heating menstruum effected the same degree of destruction of the spores within a 2 min period at the same temperature. From a series of thermal destruction and alkaline destruction curves, an empirical equation expressing the relationship between the death rate of bacterial spores, and the intensity of temperature and the concentration of alkali was established. The equation reveals that the death rate of bacterial spores is affected in an exponential manner by temperature and in a direct relationship by alkali concentration. Using the equation, sterilization time for various combinations of temperature and alkali concentration was determined and the overall correlation index between the experimental data and computed value was 0.877.

    EFFECT of LAURIC ACID ADDITION ON the ANTIMICROBIAL EFFICACY and WATER PERMEABILITY of CORN ZEIN FILMS CONTAINING NISIN (2000)

    Notes: The effect of the addition of lauric acid and nisin to corn zein films on the water permeability and inhibition of bacterial growth was examined using two methods. A zone of inhibition test on solid media and a log reduction assay with the film exposed to a bacterial culture (Lactobacillus plantarum) in liquid media (cell count method) for six hours were conducted. the corn zein cast films contained nisin (5.0 mg nisin/g film and lauric acid at 0, 4, and 8% (w/w). the highest level of lauric acid addition (8%) significantly lowered the film water permeability compared to the 4 and 0% levels. the zone of inhibition test on solid media showed no clear inhibitory zones for films containing lauric acid alone, but did produce clear zones for films with nisin with or without lauric acid. Zone size decreased as the level of lauric acid increased or with decreased water permeability. Cell counts in liquid media exposed to film were reduced by the addition of lauric acid alone to the film. the nisin alone and in combination with lauric acid in the film reduced cell numbers in the cell count as well as increased zone size in the zone assay. No additional cell reductions were found when lauric acid and nisin were combined in the films compared to films containing lauric acid alone. Nisin alone was not as effective in reducing cell counts as 8% lauric acid. Log reductions for the nisin only treatment were 2 logs after 1 h and 3 logs after 4 h. However, while the lauric acid only treatment achieved the same ultimate 5.5 log reduction, the 1 and 2 h reductions were 0 and 1 logs, respectively.
