Evaluation of exoenzyme activities, biofilm formation, and co-hemolytic effect in clinical isolates of Candida parapsilosis species complex
No full textCandida parapsilosis species complex is considered as important emerging pathogens and little is known about their pathogenicity factors and co-hemolytic activity with different bacteria species. The aim of this study was to determine in vitro exoenzyme activities, biofilm formation, and co-hemolytic effect of different bacteria species on clinical C. parapsilosis complex isolates. In total, 67 C. parapsilosis complex isolates consist of C. parapsilosis sensu stricto 63/67 and Candida orthopsilosis 4/67 were used in this study. To determine the hemolytic activity of these species, Sabouraud dextrose sheep blood agar was used. Evaluation of the CAMP-like phenomenon carried out in the presence of Staphylococcus aureus, Staphylococcus saprophyticus, Staphylococcus epidermidis, and Streptococcus agalactiae. Tube test method with ethylenediaminetetraacetic acid-rabbit plasma was used to determine coagulase activity, and biofilm formation was assessed by the tube method in assist of Sabouraud glucose broth (8%) medium. Fisher's exact tests were used for data statistical analysis. Sixty-six of 67 (98.5%) and 3/67 (4.5%) of the species showed hemolysin and coagulase activity, respectively. Fifty-five of 67 (82.1%) of species had ability for biofilm formation, and none of the samples exhibited co-hemolytic effect in the presence of four mentioned bacteria. No significant difference was found between the level of enzyme production and biofilm formation among the isolates
Fielding Peter Carey: economy, archive, celebrity
No full text© 2018 Dr. Keyvan AllahyariThis thesis accounts for a method of reading Carey’s fiction as works of national literature in the minor register (colonial, peripheral, small) which refract a sense of the possibility of circulation in transnational literary markets. The publication of Carey’s debut work, The Fat Man in History, by the University of Queensland Press in 1974 coincided with the termination of The Traditional Markets Agreement, which resulted in assisting American publishers to roam more freely in the Australian literary market. Drawing on Pierre Bourdieu’s concepts of the literary field, capital, and habitus, my thesis starts by examining the publication of The Fat Man as a microevent to better understand the macroevent of Carey’s position-taking in the transnational marketplace. The mid-1970s shifted Carey’s position in the field and established a trajectory through which he accumulated significant cultural and economic capital in the following decades. This method interrogates Carey’s rising visibility in relation to the construction of a new status for the postcolonial authors and the possibilities of the global publishing industry since the 1960s throughout to the present moment, including the politics of literary prizes and literary festivals, the rise of literary agents, the commodification of literary archives, and the merging of conglomerate publishing houses.
Carey’s fiction exhibits the anxieties of an Australian author ensnared in neoliberal systems of literary production and distribution, a free market economy biased against national territories (such as Australia) on the periphery of a world republic of letters. Drawing on the sociological paradigm of Pierre Bourdieu, this thesis asks how, and to what extent, can we think of Carey’s fiction and his writerly persona as cultural objects circulating within the global literary marketplace? How does his fiction refract the global forces that produce and distribute his books and celebrity? And what is the relationship between Carey’s stories and the literary marketplace, between the making of his books and the reading of them? Thus, my study offers a lateral examination of two interrelated aspects of Carey’s fiction. On the one hand, it captures a continuum of Australian and transnational practices of literary distinction and advancement that governed the critical and financial success of Carey’s fiction; on the other, it produces insights into the structural homologies between the literary spaces that Carey inhabits and those of his Australian characters confined to minor systems of cultural production and consumption

No full textEvaluation of CAMP-Like Effect, Biofilm Formation, and Discrimination of<i>Candida africana</i>from Vaginal<i>Candida albicans</i>Species
No full textCandida africana asa species recovered from female genital specimens is highly close toC. albicans. The present study was conducted to discriminateC. africanafrom presumptive vaginalC. albicansstrains by molecular assay and evaluate their hemolysin activity, biofilm formation, and cohemolytic effect (CAMP) with vaginal bacterial flora. A total of 110 stock vaginalC. albicansisolates were examined byHWP1gene amplification. Hemolysin activity and the ability of biofilm formation were evaluated by blood plate assay and visual detection methods, respectively.Staphylococcus aureus,Staphylococcus epidermidis, andStreptococcus agalactiaewere used to evaluate the CAMP-like effects in Sabouraud blood agar media. Based on the size of the amplicons (941 bp), all isolates were identified asC. albicans. All samples were able to produce beta-hemolysin. Moreover, 69 out of 110 of the isolates (62.7%) were biofilm-positive, 54 out of 110Candidaisolates (49%) demonstrated cohemolytic effects withS. agalactiae, and 48 out of 110 showed this effect withS. aureus(43.6%). All isolates were CAMP-negative withS. epidermidis. We detected all isolates asCandida albicansand almost half of the isolates were CAMP-positive withS. aureusandS. agalactiae, suggesting that these bacteria increase the pathogenicity ofCandidain vaginal candidiasis.</jats:p

No full textFrom Corpus to Bio-Text; Peter Carey’s Archives as Literary Networks
No full textCarey's archives add a new facet to Carey’s public image as an Australian author. In principle, the archive is directed at posterity, defying the ephemeral nature of “personality” pieces about the writer, a phenomenon that Grahame Turner has discussed in terms of Carey’s active participation in accumulating recognition amounting to the construction of Carey’s author-persona as a “national celebrity” (136). My interest in this essay is to explore the ways that Carey’s archives contribute to our understanding of productive mechanisms of his celebrity. In doing so, I theorize the formation and the significance of Carey’s archives both as texts and objects. I argue that the archiving of Carey is energized by a collective investment by a body of cultural participants who have a stake in promoting the now ‘globalised’ author. This has ultimately resulted in relocalising the ‘corpus’ of the New York based writer back in Australia, and particularly in the State Library of Victoria in Melbourne. This archive has been regularly updated alongside Carey’s growing oeuvre. In this parallel literary space, however, Carey’s cultural agency continues to manipulate his public persona.
Digital Signal Processing for a Wireless ECG Device: Wireless Electrocardiogram (WiECG)
No full textThe goal of the WiECG project is to create a prototype device that makes it possible to perform a 12-lead ECG measurement on patients without wires from the patient to a monitor. The solution consists of a transmitter and receiver, one of which is close or on the patients body and the other is connected to a monitor.This thesis describes the design and implementation of a subsystem of the prototype device that performs digitization, digital processing and reconstruction of the measured 12-lead ECG signal. This concerns converting nine 0 to 3.3V analog signals to the digital domain by using Analog-to-Digital converters, real-time filtering of nine signals with multiple digital IIR filters and reconstructing nine digital signals to the analog domain using Digital-to-Analog converters. Furthermore, component selection, design decisions and the implementation process will be detailed in this document.The subsystem proposed in this paper is able to successfully sample, efficiently filter and reconstruct nine signals in real time. Recommendations on improving the implementation to better adhere to the lower power requirements for a longer battery life are provided as future research prospects.Computer Engineerin
