Published 1991Staff ViewISSN: 0025-116XKeywords: Chemistry ; Polymer and Materials ScienceSource: Wiley InterScience Backfile Collection 1832-2000Topics: Chemistry and PharmacologyPhysicsNotes: Many complexes of biological interest, like nucleosomes or v bodies and DNA-protein complexes, can be modelled like a structure composed by a sphere joined to a rigid rod or to a flexible chain of identical beads. In this work we present a theoretical study using these models for the evaluation of some reduced conformational and hydrodynamic properties: end-to-end distance, radius of gyration and translational friction coefficient. Two kinds of models were employed: a sphere joined to one of the two ends of a rod or chain and a sphere joined to the halfpoint of a rod or chain, i. e. the models show one or two arms, respectively. Several cases were studied, varying the number of chain beads N = 10, 20, 30, … 60 (with radius σ ≤ 1/2 and bond length b = 1) and the radius of the sphere R = 1, 2, 4, 8 (in units of b). For the flexible models the position of the chain beads have been obtained randomly from Monte Carlo simulations. For these models we have made also a statistical treatment in order to obtain averaged values of the conformational and hydrodynamic properties. Finally, we conducted a comparison of our theoretical results with the experimental data for nucleosomes. The overall agreement is good and gives confidence in the applicability of our results to similar macromolecular complexes.Additional Material: 1 Ill.Type of Medium: Electronic ResourceURL: -

ISSN: 1439-0973Source: Springer Online Journal Archives 1860-2000Topics: MedicineDescription / Table of Contents: Zusammenfassung Es wurde die Wirksamkeitin vitro von Ciprofloxacin bei 570 Ampicillin-resistentenEnterobacteriaceae- und 286Pseudomonas aeruginosa-Stämmen untersucht. 95,26% derEnterobacteriaceae- und 53,45% derP. aeruginosa-Stämme wurden mit 0,1 mg/l Ciprofloxacin gehemmt. 2 mg/l von Ciprofloxacin hemmten alleEnterobacteriaceae-Stämme und 4 mg/l alleP. aeruginosa-Stämme. Bei denEnterobacteriaceae-Stämmen wurde die Wirksamkeit von Ciprofloxacin mit der von Temocillin verglichen. Bei den nach Carbenicillin- und Gentamicin-resistenten Isolaten klassifiziertenP. aeruginosa-Stämmen verglichen wir die Aktivität von Ciprofloxacin und Ceftazidim. Bei den den untersuchtenEnterobacteriaceae-Stämmen ist die Wirksamkeit von Ciprofloxacinin vitro höher als die von Temocillin und bei denP. aeruginosa-Stämmen höher als die von Ceftazidim.Notes: Summary We studied thein vitro activity of ciprofloxacin against 570 strains of ampicillin-resistantEnterobacteriaceae and 286Pseudomonas aeruginosa strains. 95.26% of theEnterobacteriaceae and 53.45% of theP. aeruginosa were inhibited by 0.1 mg/l of ciprofloxacin. 2 mg/l of ciprofloxacin inhibited all of theEnterobacteriaceae strains and 4 mg/l all of theP. aeruginosa. We compared the activity of ciprofloxacin with that of temocillin in theEnterobacteriaceae strains. In theP. aeruginosa strains, classified according to their susceptibility to carbenicillin and gentamicin, we compared the activity of ciprofloxacin with that of ceftazidime. In the strains studied, thein vitro activity of ciprofloxacin is superior to that of temocillin against theEnterobacteriaceae and to that of ceftazidime against theP. aeruginosa strains.Type of Medium: Electronic ResourceURL: -

ISSN: 1439-0973Source: Springer Online Journal Archives 1860-2000Topics: MedicineDescription / Table of Contents: Zusammenfassung Die MHK für Amoxicillin, Mezlocillin und BRL 25000 sowie eine Kombination von zwei Teilen Amoxicillin plus einem Teil Clavulansäure (2AM + 1CA) wurde für 331Enterobacteriaceae-Stämme getestet; alle diese Stämme produzierten β-Laktamasen, die mit Nitrocefin nachgewiesen worden waren. Die MHK-Werte für Mezlocillin und die Kombination 2AM + 1CA waren bei den untersuchten Stämmen insgesamt sehr ähnlich. Bei der getrennten Auswertung nach Stämmen und Keimarten ergeben sich für die überprüften Wirkstoffe drei Empfindlichkeitsgruppen: 1) Keimarten mit der gleichen oder einer ähnlichen Empfindlichkeit für Mezlocillin und 2AM + 1CA (Escherichia coli, Shigella spp., Amoxicillin-resistente Stämme), 2) Keimarten, die für Mezlocillin empfindlicher waren als für die Kombination 2AM + 1CA (Citrobacter spp.,Enterobacter cloacae, Serratia spp., indolpositiveProteus spp. sowie solche Stämme vonE. coli undShigella spp., die eine Cephalosporinase produzieren und auf Amoxicillin ansprechen), 3) Keimarten, die für 2AM + 1CA empfindlicher sind als für Mezlocillin (Amoxicillin-resistenteSalmonella spp.,Proteus mirabilis undKlebsiella pneumoniae). Diese deutliche komplementäre Wirkung von Mezlocillin und 2AM + 1CA aufEnterobacteriaceae hängt von den Stammeigenschaften und der gebildeten β-Laktamase ab.Notes: Summary The MICs of amoxicillin, mezlocillin and BRL 25,000, a combination of two parts amoxicillin and one part clavulanic acid (2AM + 1CA), were measured for 331Enterobacteriaceae strains which produced beta-lactamases as demonstrated by nitrocefin. The MIC values for mezlocillin and the combination 2AM + 1CA were very similar for the total number of the strains investigated. When investigated separately according to the bacterial species, three different sensitivity groups were established for the above-mentioned preparations: 1) species with the same or similar sensitivity to mezlocillin and 2AM + 1CA (Escherichia coli andShigella spp., amoxicillin-resistant strains); 2) species which were more sensitive to mezlocillin than to the combination 2AM + 1CA (Citrobacter spp.,Enterobacter cloacae, Serratia spp. and indole-positiveProteus as well as strains ofE. coli andShigella spp. which produce a cephalosporinase and are sensitive to amoxicillin); 3) species which are more sensitive to 2AM + 1CA than to mezlocillin (amoxicillin-resistantSalmonella spp.,Proteus mirabilis andKlebsiella pneumoniae). This complementary activity of mezlocillin and 2AM + 1CA againstEnterobacteriaceae depended on the beta-lactamases produced.Type of Medium: Electronic ResourceURL: -

ISSN: 1435-4373Source: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract Twenty-three penicillinase-producing strains ofNeisseria gonorrhoeae were characterized. All strains showed hybridization with a TEM-1 probe and production of a TEM-1 type beta-lactamase (pI 5.4) on isoelectric focusing. Eight strains also showed a beta-lactamase band of pI 5.5. The penicillin MICs for the strains producing only TEM-1 were in the range 4–16 µg/ml; MICs of the strains with the additional pI 5.5 band were≥128 µg/ml for seven strains and 4 µg/ml for an arginine-hypoxanthine dependent strain. The association of the high MICs with the presence of the pI 5.5 band was statistically significant. The pI 5.5 band could represent a new beta-lactamase type or a TEM-1 mutant.Type of Medium: Electronic ResourceURL: -
