    Bacterial interactions with silver (1990)
    Springer
    BioMetals 3 (1990), S. 151-154 
    Details
    ISSN: 1572-8773
    Keywords: Silver ; Nickel ; Bacteria ; Toxicity ; Metal tolerance ; Accumulation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Summary This review examines interactions between bacteria and the biologically non-essential metal, silver. Aspects of silver toxicity, tolerance and accumulation (possible binding and uptake as opposed to energy-dependent transport) in bacteria are discussed. In addition, plasmid biology is examined briefly since little information is available on the exact mechanism(s) of plasmid-endoced silver resistance in bacteria.

    Selective digestive decontamination in multiple trauma patients: Cost and efficacy (1995)
    Springer
    Pharmacy world & science 17 (1995), S. 12-16 
    Details
    ISSN: 1573-739X
    Keywords: Antibiotics ; Bacteria ; Clinical trials ; Costs and cost analysis ; Drug utilization ; Infection ; Multiple trauma ; Selective digestive decontamination
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract A double-blind randomized placebo-controlled study was carried out to evaluate the efficacy and the cost of selective digestive decontamination (SDD) to prevent nosocomial pneumonia in multiple-trauma patients. Nosocomial infections, particularly pneumonia, were more frequent in the placebo group. The most common infectious agent wasStaphylococcus: Staphylococcus aureus in the placebo group andStaphylococcus epidermidis in the SDD group. Methicillin-resistantStaphylococcus epidermidis was detected more often in the SDD group. No methicillin-resistantStaphylococcus aureus was observed in this study. Fewer patients in the SDD group required antibiotherapy. SDD resulted in a saving of about 41% in drug expenditure.

    Distribution of naturally occurring quinones (1991)
    Springer
    Pharmacy world & science 13 (1991), S. 70-73 
    Details
    ISSN: 1573-739X
    Keywords: Algae ; Angiosperms ; Arthropods ; Bacteria ; Fungi ; Lichens ; Marine animals ; Quinones, naturally occurring
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Angiosperms, fungi (including lichens), and bacteria are the main sources of natural quinones. Small numbers are present in algae, ferns, conifers, sponges, echinoderms, other marine animals, and arthropods. In angiosperms quinones have some chemotaxonomic value at the genus and family level but more surveys are required.

    Stability of buprenorphine, haloperidol and glycopyrrolate mixture in a 0.9 % sodium chloride solution (1999)
    Springer
    Pharmacy world & science 21 (1999), S. 272-274 
    Details
    ISSN: 1573-739X
    Keywords: Stability ; Buprenorphine ; Glycopyrrolate ; Haloperidol ; Polypropylene ; Polyvinyl chloride ; PVC ; Syringes ; Cassettes ; Bacteria
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Combinations of opioids and adjuvant drug solutions are often used in clinical practice while little information is available on their microbiological or chemical stability. Currently there are no commercially available, prepacked, ready‐to‐use epidural or subcutaneous mixtures. Thus, epidural and subcutaneous analgesic mixtures must be prepared in the pharmacy on an as‐needed basis. Such mixtures are typically used for the treatment of severe pain in cancer patients. The aim of this study was to investigate the microbiological and chemical stability of a buprenorphine, haloperidol and glycopyrrolate mixture in a 0.9% sodium chloride solution. A high performance liquid chromatographic (HPLC) method and pH‐meter were used to conduct the analyses. Antimicrobial activity of each component was studied by an agar dilution method. According to the results from the chemical and microbiological stability studies, this mixture can be stored in polypropylene (PP) syringes and polyvinyl chloride (PVC) medication cassettes for at least 30 days at either 21 °C or 4 °C, and for 16 days in PP syringes at 36 °C, and for 9 days in PVC medication cassettes at 36 °C.

    Qualitative gas chromatographic analysis of bacterial amines as their Schiff bases and other derivatives (1983)
    Springer
    Chromatographia 17 (1983), S. 318-321 
    Details
    ISSN: 1612-1112
    Keywords: Bacteria ; Amines ; Gas Chromatography ; Schiff bases ; OV-17
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Summary Columns of SE-30 and OV-17 on Chromosorb W, Apiezon N on Chromosorb G and Tenax-GC porous polymer were compared for their ability to separate bacterial amines converted to carbethoxy, dinitrophenyl, trimethylsilyl, Schiff base and fluorinated Schiff base derivatives. Tenax-GC performed less well than the other packings with respect to the number of plates and peak resolution. Dinitrophenyl and trimethylsilyl derivatives were both unsatisfactory for analysis of bacterial amines. Schiff bases and their fluorinated derivatives were found to be the most suitable. However, the former were preferred as the use of fluorinated Schiff bases confered little advantage when a flame ionization detector was employed. A maximum of 16 amines was separated, using columns of OV17 on Chromosorb W programmed from 110 °C to 280 °C at 5.5 °C min−1 after an initial holding time of 6 min. The application of the method to analysis of cultures ofProteus mirabilis yielded two amines tentatively identified asiso-butylamine andiso-amylamine.

    Trans-esterification of fatty acids from microorganisms and human blood serum by trimethylsulfonium hydroxide (TMSH) for GC analysis (1990)
    Springer
    Chromatographia 30 (1990), S. 245-248 
    Details
    ISSN: 1612-1112
    Keywords: Gas chromatography ; Trimethylsulfonium hydroxide (TMSH) ; FAME analysis ; Bacteria ; Blood serum
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Summary Trimethylsulfonium hydroxide (TMSH) can convert fatty acids into the corresponding fatty acid methyl esters (FAMEs) in a single step. These fatty acids may also be bound in biomolecules such as phospholipids and/or glycerides. Complex mixtures of saturated and unsaturated FAMEs which may contain hydroxy and cylopropyl groups are obtained by trans-esterification; they can easily be separated in most cases by capillary GC. When FAMEs are generated from different microorganisms e.g. bacteria the patterns of the chromatograms are characteristic. Examples of characteristic patterns of bacteria with different cell wall structures are shown. The described method of transesterification can also be applied directly to blood serum without sophisticated sample pretreatment. The profiles of the chromatograms match well those described in the literature obtained by other methods of trans-esterification or sample preparation.

    Behavioral responses to chemical cues by bacteria (1986)
    Springer
    Journal of chemical ecology 12 (1986), S. 1071-1089 
    Details
    ISSN: 1573-1561
    Keywords: Bacteria ; chemotaxis ; methyl-accepting chemotaxis proteins ; molecular biology ; signal transduction ; switch proteins
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Bacterial chemotaxis presents a model sensory system in which cells modulate the direction of rotation of their flagella in response to gradients of certain chemicals. The chemotactic machinery ofEscherichia coli is currently being systematically reduced to its individual components through the accomplishments of behavioral, physical, genetic, molecular genetic, and biochemical analyses. Thirteen of the so called “MCP-related” class of chemotaxis gene products are known. Transmembrane methyl-accepting chemotaxis proteins (MCPs) are important for the chemical sensing, signal generation, and sensory adaptation processes. Soluble chemotaxis proteins relay information from these MCPs to structural components of the flagella referred to as switch proteins. Emphasis here is on the separate roles each of these groups of chemotaxis proteins perform, as well as their protein-protein relationships.
