The Twin-Arginine Translocation Pathway of Mycobacterium smegmatis Is Functional and Required for the Export of Mycobacterial β-Lactamases

ABSTRACT The twin-arginine translocation (Tat) pathway exports folded proteins across the bacterial cytoplasmic membrane and is responsible for the proper extracytoplasmic localization of proteins involved in a variety of cellular functions, including pathogenesis. The Mycobacterium tuberculosis and Mycobacterium smegmatis genomes contain open reading frames with homology to components of the Tat export system (TatABC) as well as potential Tat-exported proteins possessing N-terminal signal sequences with the characteristic twin-arginine motif. Due to the importance of exported virulence factors in the pathogenesis of M. tuberculosis and the limited understanding of mycobacterial protein export systems, we sought to determine the functional nature of the Tat export pathway in mycobacteria. Here we describe phenotypic analyses of ΔtatA and ΔtatC deletion mutants of M. smegmatis, which demonstrated that tatA and tatC encode components of a functional Tat system capable of exporting characteristic Tat substrates. Both mutants displayed a growth defect on agar medium and hypersensitivity to sodium dodecyl sulfate. The mutants were also defective in the export of active β-lactamases of M. smegmatis (BlaS) and M. tuberculosis (BlaC), both of which possess twin-arginine signal sequences. The Tat-dependent nature of BlaC was further revealed by mutation of the twin-arginine motif. Finally, we demonstrated that replacement of the native signal sequence of BlaC with the predicted Tat signal sequences of M. tuberculosis phospholipase C proteins (PlcA and PlcB) resulted in the Tat-dependent export of an enzymatically active ′BlaC. Thus, ′BlaC can be used as a genetic reporter for Tat-dependent export in mycobacteria.
Session 5: Nutrition communication The role of trust in health communication and the effect of conflicts of interest among scientists

One of the key challenges facing efforts to translate nutrition research into public health recommendations is understanding how the public will respond to these efforts, including whether they will trust the information. Among factors that influence trust in health communication is the extent to which the sources of the information are considered accurate, balanced, fair and unbiased. In relation to bias, few issues rise to as high a level of concern as the suspicion of conflicts of interest among scientists. Sometimes, even the perception of conflict of interest is enough to cast doubt on the integrity of the research and credibility of the results. The present paper provides an overview of research on conflicts of interest in science, including ways in which it has touched the field of nutrition. It then offers data on public views about conflicts of interest in science, including the extent to which funding sources influence trustworthiness of the research. The conclusions suggest implications for translational research in nutrition.
Screening and enumeration of lactic acid bacteria in milk using three different culture media in Petrifilm™ Aerobic Count plates and conventional pour plate methodology

This study aimed to compare Petrifilm™ Aerobic Count (AC) plates and the conventional pour plate methodology using de Mann-Rogosa-Sharpe (MRS), Kang-Fung (KF) and Kang-Fung-Sol (KFS) culture media for screening and enumeration of lactic acid bacteria (LAB) in milk. Suspensions of 10 LAB species in reconstituted powder skim milk and 30 raw milk samples, without experimental inoculation, were tested. For selective enumeration, all samples were previously diluted in MRS, KF and KFS broths and then plated in Petrifilm™ AC and conventional pour plate methodology, using the same culture media with added agar. All plates were incubated at 37°C for 48 h in anaerobic conditions. Differences in the counts were observed only for raw milk samples using KFS in conventional methodology, when compared with the counts obtained from MRS and KF (P⩽0·05). The results showed excellent correlation indexes between both methodologies using the three culture media for LAB suspensions (r=0·97 for MRS, KF and KFS). For raw milk samples, the correlation indexes were excellent (r=0·97, for MRS) and good (r=0·84 for KF, and r=0·82 for KFS), showing some interference in Petrifilm™ AC when supplements were added, especially lactic acid. These results indicate the possibility of using Petrifilm™ AC plates for enumeration of LAB in milk, even with the use of selective supplements.

CULICOIDES AND OTHER BITING FLIES ON THE PALOS VERDES PENINSULA OF SOUTHERN CALIFORNIA, AND THEIR POSSIBLE RELATIONSHIP TO EQUINE DERMATITIS

ABSTRACT Biting insects were sampled to investigate the cause(s) of dermatitis (putative Culicoides hypersensitivity [CHS]) on horses on the Palos Verdes Peninsula, Los Angeles County, California. Suction traps baited with CO2 were operated at 5 sites from April 2002 to August 2003, supplemented by sampling from horses. Six species of Culicoides, 7 species of mosquitoes, and occasional Simulium and Stomoxys were collected in traps. Culicoides sonorensis was the most common midge trapped, although C. obsoletus and C. freeborni also were collected repeatedly. Insects from the belly region of horses in spring (peak dermatitis period) were mostly C. obsoletus, which were far more abundant than indicated by CO2-baited suction traps. The predominant mosquito was Culiseta incidens; Culex quinquefasciatus and Cx. tarsalis also could be common, depending on the site. Mosquitoes, particularly Cs. incidens, were more abundant the 2nd year (normal rainfall), whereas C. sonorensis and C. freeborni were more abundant the 1st year (drought period). Culicoides obsoletus, supplemented by C. sonorensis, is regarded as a primary suspect causing CHS in this area.
Cognitive Maturity and the Questioning Strategies Used by Learning Disabled and Normal Subjects: A Comparative Study

The investigators used the Twenty Questions game to examine differences in cognitive maturity and questioning strategies between 44 matched normal and learning disabled subjects. Subjects were subdivided into three groups, (prior, transition, and formal operations) on the basis of their chronological age and corresponding theoretical Piagetian cognitive maturity level. Group differences were statistically analysed using the non-parametric Mann-Whitney U test. Results revealed non-significant differences for the learning disabled and normal prior and transition groups. The learning disabled and normal children in the formal operations groups, however, differed significantly in terms of the cognitive maturity of their strategy utilization during the Twenty Questions task. Implications for cognitive strategy-training programmes with adolescents are examined in the light of the findings.
Diophantine-equation based arithmetic test set embedding

In this paper we show first that finding the location of a test vector in the sequence generated by an accumulator driven with an odd additive constant C is equivalent to the solution of a linear Diophantine equation with two variables. The latter equation is known to be solved fast in linear time. We then show that only one Diophantine equation needs to be solved per test set irrespective of the number of patterns in it. The finding of the locations of all patterns of a given test set T in the sequence generated under a constant C is done in O(n+ | T |) steps instead of O(n middot |T|) steps of a previous approach. Next we present a method which, given a test set T, and an odd constant C, finds the seed in the sequence generated under C that can reproduce all patterns of T in minimum length. We use this optimum technique to search for the best constant C' (in terms of short test length) in a randomly generated subset. Experimental results show the potential of the approach for test set embedding
Deep Learning on FPGAs

DEEP LEARNING ON FPGAS Griffin James Lacey Advisor: University of Guelph, 2016 Dr. Graham W. Taylor Co-Advisor: Dr. Shawki Areibi The recent successes of deep learning are largely attributed to the advancement of hardware acceleration technologies, which can accommodate the incredible growth of data sizes and model complexity. The current solution involves using clusters of graphics processing units (GPU) to achieve performance beyond that of general purpose processors (GPP), but the use of field programmable gate arrays (FPGA) is gaining popularity as an alternative due to their low power consumption and flexible architecture. However, there is a lack of infrastructure available for deep learning on FPGAs compared to what is available for GPPs and GPUs, and the practical challenges of developing such infrastructure are often ignored in contemporary work. Through the development of a software framework which extends the popular Caffe framework, this thesis demonstrates the viability of FPGAs as an acceleration platform for deep learning, and addresses many of the associated technical and practical challenges.
Mexican Adolescents' Comprehension about Bank Functions: Considerations regarding the Development of School Curricula

Mexican secondary and high school curricula do not include any economic or financial education. Furthermore, Mexico's actual banking infrastructure is not widely spread around all of the country, and several towns and villages still do not have banks. Hence it becomes difficult for adolescents to understand these institutions, which are important in the socio-economic organization of societies. In order to provide research data about levels of comprehension among adolescents of these topics, so that it can eventually be considered by Mexican authorities that produce school curricula, it was decided to develop a pilot study with a sample of 25 adolescents between 12 and 16 years of age from a middle-class socio-economic context, who were individually interviewed about bank functioning, interest rates and the difference between credit and debit cards. Subjects were tested individually in their schools by the researchers and the interviews lasted approximately 25 minutes. All interviews were audio taped and later transcribed. Results show that the majority of subjects understand interest rates on loans but cannot relate them to interest rates on deposits. They also confuse credit and debit cards. Data are discussed in terms of levels of comprehension and possible application to school curricula.
Gamma-ray burst precursors as the remnant of the thermal radiation initially trapped in the fireball

In the standard fireball model of gamma-ray bursts (GRBs), the fireball starts with an optically thick phase. As it expands, the fireball becomes optically thin at some stage. The thermal radiation trapped in the originally opaque fireball then leaks out, producing a transient event. The appearance of the event is investigated in the framework of a homogeneous, spherically symmetric and freely expanding fireball produced instantly by an explosive process without continuous injection of mass and energy. We find that, generally, the event has a time duration shorter than that of the main burst, which is presumably produced by the internal shock after the fireball becomes optically thin. The event is separated from the main burst by a quiescent time interval, and is weaker than the main burst at least in a high-energy band. Hence, the event corresponds to a GRB precursor. The precursor event predicted by our model has a smooth and Fast Rise and Exponential Decay (FRED) shaped light curve, and a quasi-thermal spectrum. Typically, the characteristic blackbody photon energy is in the X-ray band. However, if the distortion of the blackbody spectrum by electron scattering is considered, the characteristic photon energy could be boosted to the gamma-ray band. Our model may explain a class of observed GRB precursors - those having smooth and FRED-shaped light curves and quasi-thermal spectra.
Effective field theory approach to high-temperature thermodynamics.

An effective field theory approach is developed for calculating the thermodynamic properties of a field theory at high temperature $T$ and weak coupling $g$. The effective theory is the 3-dimensional field theory obtained by dimensional reduction to the bosonic zero-frequency modes. The parameters of the effective theory can be calculated as perturbation series in the running coupling constant $g^2(T)$. The free energy is separated into the contributions from the momentum scales $T$ and $gT$, respectively. The first term can be written as a perturbation series in $g^2(T)$. If all forces are screened at the scale $gT$, the second term can be calculated as a perturbation series in $g(T)$ beginning at order $g^3$. The parameters of the effective theory satisfy renormalization group equations that can be used to sum up leading logarithms of $T/(gT)$. We apply this method to a massless scalar field with a $\Phi^4$ interaction, calculating the free energy to order $g^6 \log g$ and the screening mass to order $g^5 \log g$.
Correlation Clustering with Low-Rank Matrices

Correlation clustering is a technique for aggregating data based on qualitative information about which pairs of objects are labeled `similar' or `dissimilar. ' Because the optimization problem is NP-hard, much of the previous literature focuses on finding approximation algorithms. In this paper we explore how to solve the correlation clustering objective exactly when the data to be clustered can be represented by a low-rank matrix. We prove in particular that correlation clustering can be solved in polynomial time when the underlying matrix is positive semidefinite with small constant rank, but that the task remains NP-hard in the presence of even one negative eigenvalue. Based on our theoretical results, we develop an algorithm for efficiently ``solving'' low-rank positive semidefinite correlation clustering by employing a procedure for zonotope vertex enumeration. We demonstrate the effectiveness and speed of our algorithm by using it to solve several clustering problems on both synthetic and real-world data.
Students in Europe: motives for studying, expectations of higher education and the relevance of career prospects*

In the context of the ongoing debate with respect to higher education policy and research, today's student generation is compared with earlier ones, and differences are often stated, or assumed, in thought, values, behaviour and ability. In the Federal Republic of Germany, the thesis to the effect that the present generation of youth and students represents a 'new socialisation type' is the subject of considerable attention (Ziehe, 1975). This 'new type', it is argued, is a product of changes in early childhood experiences within the nuclear family, which in turn are a result of the nature of production under late capitalism. The 'new type' is described as having narcissistic and passive tendencies, a fear of failure, a lack of ambition, a reluctance to get involved in conflict and a diminished sense of self. Less interest in training and education, indifference, unwillingness to learn and a lack of involvement in university issues are other typical signs the advocates of this thesis would see among students. Other assumptions and hypotheses, which are not based upon psychoanalytical considerations, are also felt to point in the direction of-supposedly newareas of conflict in university education, in communication and motivation, for example, and changes of a basic nature are seen in the values and priorities of students. The conclusion is that higher education is no longer relevant for students and that traditional factors such as personal education and self-improvement are no longer considered important either by the universities or the students themselves. According to a widespread argument, a constantly growing segment of the student population sees higher education as a path to a career, whereas another group has no orientation and remains indifferent. Yet a third group seeks 'fulfillment' outside the
Fetuin-A is inversely associated with coronary artery calcification in community-living persons: the Multi-Ethnic Study of Atherosclerosis.

BACKGROUND Fetuin-A is a hepatic secretory protein that inhibits arterial calcification in vitro. The association of fetuin-A with coronary arterial calcification (CAC) in the general population is uncertain. METHODS Among 2457 community-living individuals without cardiovascular disease (CVD), we measured serum fetuin-A concentrations by ELISA and evaluated the cross-sectional association of fetuin-A with CAC prevalence (any vs none) and severity; on follow-up 3.2 years (median) later, we evaluated the association of fetuin-A with CAC incidence and progression. RESULTS The mean age was 62 (SD 10) years, and the mean fetuin-A concentration was 0.48 (0.10) g/L. At baseline, 1200 individuals (49%) had CAC, and 272 individuals developed CAC during follow-up. At baseline, there was a threshold effect at the lowest fetuin-A quartile with CAC prevalence. In models adjusted for demographics, traditional cardiovascular disease (CVD) risk factors and kidney function, the lowest fetuin-A quartile had 7% (95% CI 1%-13%; P = 0.04) greater CAC prevalence compared with quartiles 2-4. Similar associations were observed with CAC severity at baseline, but the association was more linear. Each SD (0.10 g/L) lower fetuin-A was associated with a 12% (95% CI 3%-21%; P = 0.01) greater CAC severity in adjusted models. There was no significant association of fetuin-A with CAC incidence or progression. CONCLUSIONS Fetuin-A is inversely associated with CAC severity among community-living individuals without CVD. Whether fetuin-A concentrations are associated with incident CVD event in the general population requires future study.
The (gay) scene of racism: Face, shame and gay Asian males

As adept as we have become in tracing the discursive and institutional contours of contemporary Australian racisms, such a focus sometimes shifts attention away from the ‘lived experience’ of racism, in Fanon’s sense. What does it mean to face racism? What does it mean for gay Asian men to face racism on the gay scene? How is it possible to face racism? Indeed, do we face racism or does racism ‘face’ us? Drawing on autoethnographic research, this essay focuses on the lived experience of antiAsian racism on the gay scene. It analyses cultural examples of racial wounding on the gay scene to tease out the constitutive role of shame for gay Asian men’s racial-sexual subjectivities.
In vivo antiplasmodial activity of ZS-2A: a fraction from chloroform extract of Zizyphus spina-christi root bark against Plasmodium berghei berghei in mice

Zizyphus spina-christi is used in ethnomedical practice for the treatment of fever. Bio-assay guided investigation of the plant’s root bark was initiated and ZS-2A, a fraction from the chloroform extract of the material, eluted with hexane-ethylacetate (50:50) using flash column chromatography, was evaluated for in vivo antiplasmodial activity against Plasmodium berghei in mice. Four-day suppressive, curative effect against established infection and prophylactic models of antiplasmodial studies were used. The fraction (25, 50 and 100 mg/kg, p.o.) showed a potent activity against the parasite in the suppressive and curative tests. The result suggests that ZS-2A may be a promising agent for malaria treatment. © 2007 International Formulae Group. All rights reserved.
One Hundred Anti‐Ro (SS‐A) Antibody Positive Patients: A 10‐Year Follow‐Up

To explore further the varied clinical expression of anti-Ro(SS-A) antibody positive patients and to determine the outcomes of these patients, we followed 100 anti-Ro(SS-A) antibody positive patients, originally seen at the Johns Hopkins Medical Institutions in 1982 and 1983, over a 10-year period. The results of this study indicate that anti-Ro(SS-A) antibody positive patients have a diverse clinical presentation and that the anti-Ro(SS-A) antibody response generally persists for years. Some of these patients appear to have a static disease process for years. However, 65% (51, including 13 deaths, of 78 patients) of the patients for whom we had follow-up data had a chronic (10 years or greater) progressive disease process. Black patients, in general, have an earlier onset of disease and may have a more severe disease than white patients. At least 25% of our anti-Ro(SS-A) antibody positive patients demonstrated a dynamic change in clinical presentation with the development of Sjögren syndrome and/or a progressive "rheumatoid-like" arthritis. Interstitial pulmonary disease, central nervous system disease, and vasculitic insults occur frequently in these patients. Renal disease occurred in 19 anti-Ro(SS-A) positive patients, and in 47% of these renal disease patients, no anti-DNA antibodies (dsDNA or ssDNA) were detected. Cutaneous manifestations are prominent in anti-Ro(SS-A) antibody positive patients with lupus. Photosensitivity and a malar dermatitis were the most common features. Twenty percent of lupus patients had discoid lesions, and 20% had SCLE lesions. Based on this study, we believe that anti-Ro(SS-A) antibody positive patients should be routinely evaluated for the emergence of systemic features. Since these systemic features are at least in part, if not solely, the result of inflammation, early treatment with steroids and/or immunosuppressive agents may minimize the damage and influence in a positive manner the significant morbidity and mortality observed in some anti-Ro(SS-A) antibody positive patients.
