Efficacies of piperacillin-tazobactam and cefepime in rats with experimental intra-abdominal abscesses due to an extended-spectrum beta-lactamase-producing strain of Klebsiella pneumoniae.
No full textThe in vivo activities of piperacillin-tazobactam and cefepime were compared with
those of ticarcillin-clavulanate, ceftazidime, cefotaxime, and imipenem in a rat
model of intra-abdominal abscess with a strain of Klebsiella pneumoniae
elaborating an extended-spectrum beta-lactamase (TEM-26). With the exception of
ceftazidime, all of the antimicrobial agents significantly reduced bacterial
counts within abscesses at the end of therapy compared with those in untreated
controls. Residual viable cell counts (mean +/- standard deviation in log10
CFU/gram) were as follows: control, 8.76 +/- 0.97; ceftazidime, 8.00 +/- 0.76;
piperacillin-tazobactam, 3.87 +/- 1.72; ticarcillin-clavulanate, 3.74 +/- 1.34;
cefepime, 3.15 +/- 1.19; cefotaxime, 2.61 +/- 0.77; imipenem, 2.41 +/- 0.93.
Imipenem was more effective than either of the inhibitor combinations (P < 0.05).
Cefotaxime was unexpectedly effective given its poor in vivo activity against
this organism in our earlier studies, which used a different dose and total
duration of therapy (L. B. Rice, J. D. C. Yao, K. Klimm, G. M. Eliopoulos, and R.
C. Moellering, Jr., Antimicrob. Agents Chemother. 35:1243-1244, 1991). These
observations suggest that the effectiveness of cephalosporins in the treatment of
experimental infections caused by extended-spectrum beta-lactamase-producing K.
pneumoniae may be highly dependent on dosing regimens, even for a specific
organism and site of infection

Geochemistry and origin of the Asimotrypes carbonate hosted mesothermal gold deposit, Pangeon mountain, N. Greece
No full textThe Asimotrypes mesothermal gold deposit located in the Pangeon Mt (E. Macedonia, N. Greece), is part of the Western Rhodope Massif (WRM), which represents the metamorphic core complex of an alpine collision orogen. Alpine metamorphism, of U. Cretaceous - M. Eocene age, reached upper greenschist to lower amphibolite conditions. A low-pressure greenshist fades retrograde overprint during uplift marked the end of Alpine metamorphism in the Miocene. Post-metamorphic Miocene uplift has been recognised in the Pangeon Mt and it was ascribed to Late Cainozoic extensional tectonics.The Asimotrypes ore, of replacement and shear-zone style consists mainly of arsenopyrite, pyrite and gold, with subordinate sphalerite, galena, chalcopyrite, pyrrhotite, tetrahedrite-tennantite, marcasite, covellite and malachite. Gold is either refractory occurring mainly in arsenopyrite and to a lesser extent in Aspyrite, or free in the oxide minerals.Three types of fluid inclusions (with subtypes) were recognised based on constituent phases at room temperature and microthermometric behaviour: (i) H2O-CO2 3-phase inclusions: L1 (H2O)+L2 (CO2)+V (CO2); (ii) Aqueous 2-phase inclusions: L+V; and (iii) Naturally decrepitated and/or leaked inclusions: V or L+V. The fluids have low salinity (<5 wt % NaCl equiv.), but variable CO2/H2O ratios. Microthermometric studies in gangue quartz indicate early ore deposition at P-T conditions of 275º-310ºC and 2.7-3.1 kb during unmixing of the mineralising fluids, followed by deposition at temperatures down to 130ºC and low near surface pressures. δ34S values of primary sulphide minerals suggest a magmatic source for the sulphur. δ13C values in marble calcite are indicative of a marine environment of deposition, also supported by a plot of δ13C versus δ18O for the same samples. Calculated isotopic composition of ore fluids in quartz, sericite and whole rock at 275ºC and 340ºC are consistent with values of metamorphic fluids. Whole rock hydrogen isotopic composition of -117±7.5 (lσ) indicates that the mineralising fluid was of meteoric origin. Sr isotope data implies seawater origin for strontium. Lead isotope data in ores from the Rhodope showed that Pb is derived from crustal rock types. Sulphide species such as Au (HS)-2, were probably the most effective complexing agents for gold in the Asimotrypes fluids, which were typically low in salinity. A decrease of sulphur species activity and cooling are suggested to be the favoured depositional mechanism in a reducing environment. Combined with geological evidence, the fluid inclusion and stable data of the Asimotrypes gold ore, are consistent with genesis from deeply convecting meteoric waters driven by regional uplift through rocks undergoing retrogressive greenschist facies metamorphism

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
