Abstract:
Reliable identification of mycobacterial species by PCR-restriction enzyme analysis (PRA)-hsp65 in a reference laboratory and elaboration of a sequence-based extended algorithm of PRA-hsp65 patterns

BMC Microbiology , 2008, DOI: 10.1186/1471-2180-8-48
Abstract: A total of 434 NTM isolates were obtained from 5019 cultures submitted to the Institute Adolpho Lutz, Sao Paulo Brazil, between January 2000 and January 2001. Species identification was performed for all isolates using conventional phenotypic methods and PRA-hsp65. For isolates for which these methods gave discordant results, definitive species identification was obtained by sequencing a 441 bp fragment of hsp65. Phenotypic evaluation and PRA-hsp65 were concordant for 321 (74%) isolates. These assignments were presumed to be correct. For the remaining 113 discordant isolates, definitive identification was based on sequencing a 441 bp fragment of hsp65. PRA-hsp65 identified 30 isolates with hsp65 alleles representing 13 previously unreported PRA-hsp65 patterns. Overall, species identification by PRA-hsp65 was significantly more accurate than by phenotype methods (392 (90.3%) vs. 338 (77.9%), respectively; p < .0001, Fisher's test). Among the 333 isolates representing the most common pathogenic species, PRA-hsp65 provided an incorrect result for only 1.2%.PRA-hsp65 is a rapid and highly reliable method and deserves consideration by any clinical microbiology laboratory charged with performing species identification of NTM.The genus Mycobacterium comprises organisms that are heterogeneous in terms of metabolism, growth, environmental niche, epidemiology, pathogenicity, geographic distribution and disease association [1]. While there are notable pathogens such as Mycobacterium tuberculosis, Mycobacterium bovis and Mycobacterium leprae, most are environmental organisms typically acting as opportunistic pathogens. These species, often collectively called nontuberculous mycobacteria (NTM), have been associated with a variety of problems including pulmonary, lymph node, skin, soft tissue, skeletal, and disseminated infections as well as nosocomial outbreaks related to inadequate disinfection/sterilization of medical devices [2]. In recent years, infections due to the subset
Los jóvenes y la imaginación social en áfrica: Introducción
Durham,Deborah;
Cuadernos de antropolog?-a social , 2011,
Abstract: youth are an increasingly compelling subject for study in africa, entering into political space in highly complex ways. to pay attention to youth is to pay close attention to the topology of the social landscape - to power and agency; public, national and domestic spaces and identities, and their articulation and disjuntures; memory, history, and sense of change; globalization and governance; gender and class. in this introduction i draw attention to how youth is constructed as a problematic category and how it acts as a "social shifter" engaging the social imagination, to how youth contributes to generational debates and constructions, and to how considerations of youth challenges our thinking about agency.
Representation of Integers by Ternary Quadratic Forms: A Geometric Approach
Gabriel Durham
Mathematics , 2015,
Abstract: In 1957 N.C. Ankeny provided a new proof of the three squares theorem using geometry of numbers. This paper generalizes Ankeny's technique, proving exactly which integers are represented by $x^2 + 2y^2 + 2z^2$ and $x^2 + y^2 + 2z^2$ as well as proving sufficient conditions for an integer to be represented by $x^2+y^2+3z^2$ and $x^2 + y^2 + 7z^2$.
A política educacional do governo Fernando Henrique Cardoso: uma vis?o comparada
Durham, Eunice Ribeiro;
Novos Estudos - CEBRAP , 2010, DOI: 10.1590/S0101-33002010000300009
Abstract: the article offers a comparative analysis of the educational policies of president fernando henrique cardoso (1995-2003) taking as reference the period between 1992-2008. it demonstrates the great progress towards the universalization of basic education, the expansion of higher education and the reforms based on a new educational law. it also analyses the importance of the implementation of a comprehensive system of evaluation of all levels of education. finally it analyzes the problems related to the improvement of education quality.
Viewing society from the periphery
Durham, Eunice Ribeiro;
Revista Brasileira de Ciências Sociais , 2000, DOI: 10.1590/S0102-69092000000500002
Abstract: the article examines the cultural values and representations of the dwellers of the urban periphery, covering three middle-sized cities in the state of s?o paulo: s?o josé dos campos, rio claro and marília. it relies on the results of a research carried out at cebrap in 1982, and it also draws much ethnographic information from other dispersed sources dealing with the city of s?o paulo itself. the way people living at the periphery conceive their life in the city, their visions of the labor market, the way they see their own social progress or the social improvements available to them, as well as their images of public services and policies (from both the local and federal governments) are the main themes studied in the article. the thrust of the article is how the public and private realms emerge and interact in these people's "weltanschauung".
A educa??o no governo de Fernando Henrique Cardoso
Durham, Eunice Ribeiro;
Tempo Social , 1999, DOI: 10.1590/S0103-20701999000200013
Abstract: this work presents the evolution of the educational system during the government of fernando henrique cardoso, in the context of the transformations occurred in the last decade. the data demonstrates a clear progress in elementary education and the article analyses the implemented educational policy and the transformation, which occurred in the system during this time. a special part is dedicated to college, and it is demonstrated the existence of a crisis which affects the public institutions, mainly the federal ones. it also shows the headway in the process of evaluation of the system.
Chimpanzés também amam: a linguagem das emo??es na ordem dos primatas
Durham, Eunice Ribeiro;
Revista de Antropologia , 2003, DOI: 10.1590/S0034-77012003000100003
Abstract: the general objective of this article is to call the attention of anthropologists to new developments of biological sciences like neurobiology, primatology, ethology and studies and theories regarding evolution which should promote a revision of assumptions present in anthropology regarding the classical opposition nature-culture. this general problem is analyzed through a comparison between chimpanzees and humans, focusing on the emotional components of behavior. more specifically, it analyses ''love'' behavior and includes sexual behavior, mother-child, sibling and friendship relations. it also analyses the importance of emotional components for the constitutions and continuity of social groups. a brief mention is made regarding hierarchy, aggression and political alliances. the comparison raises questions regarding incest, homosexuality and marriage which involves also a dialogue with psychoanalysis.

A category theoretic approach to asymptotic quantum channel approximation and Birkhoff's Theorem
Ian T. Durham
Physics , 2009,
Abstract: Birkhoff's Theorem states that doubly stochastic matrices are convex combinations of permutation matrices. Quantum mechanically these matrices are doubly stochastic channels, i.e. they are completely positive maps preserving both the trace and the identity. We expect these channels to be convex combinations of unitary channels and yet it is known that some channels cannot be written that way. Recent work has suggested that $n$ copies of a single channel might approximate a mixture (convex combination) of unitaries. In this paper we show that $n(n+1)/2$ copies of a symmetric unital quantum channel may be arbitrarily-well approximated by a mixture (convex combination) of unitarily implemented channels. In addition, we prove that any extremal properties of a channel are preserved over $n$ (and thus $n(n+1)/2$) copies. The result has the potential to be completely generalized to include non-symmetric channels.
