Rewriting the memory of a Queen

Field: Arts and Humanities (Social Sciences)

Literature plays a major role as a repository of transformable memory and as a terrain where collective identity can be shaped and negotiated. This paper looks at literary representations of Dido, Cleopatra and Elizabeth I: three queens, three figurations of power in its uneasy connection with the varied discourse of womanliness – to illustrate how they have entered the cultural memory of western civilisation, forging and re-forging its self-image. In a crucial passage of Roman history, Dido and Cleopatra are clearly linked in Virgil's founding epic of the Augustan age, and the Carthaginian queen's story is a significant tessera in the past created by the narration of Aeneas's adventures, contributing powerfully to the establishment of the image of Cleopatra still prevalent in western culture. In Tudor England, with reference both to the creation of Britain's ‘Roman’ past and to the vexing question of a female sovereign, once again literature plays a major role in highlighting the political implications of the two oriental queens, as they are re-signified to become – by analogy and/or opposition – figures of Elizabeth.
Hypoxylon conostomum: cytology of the ascus

Field: Agricultural and Biological Sciences (Life Sciences)

The haploid chromosome number of Hypoxylon conostomum is seven. Ascosporesare uninucleate when formed, becoming binucleate after a mitosis. One of the two nuclei is cut off in a cellular appendage which degenerates before the ascospore becomes colored. These observations are discussed in relation to the taxonomic position of this fungus.

Hizb al-Nahdah: from revolution to government and to a second referendum

Field: Social Sciences (Social Sciences)

The year 2011 witnessed watershed events in the countries of the Middle East and North Africa (MENA), resulting in long-awaited political and social transformation, with Tunisia acting as catalyst and modus operandi for the other countries of the region. Although the so-called ‘Arab Spring’ now seems to be gripped in a stalemate in Egypt, where vagueness still prevails, and in Syria and Libya, where the security situation continues to be extremely precarious and unstable, there seems to be a wind of change in the political context in Tunisia, where on 26 October 2014 the population witnessed the second post-revolution elections. The political party Ḥizb al-Nahḍah (Renaissance Party), officially founded in 1981, has been having a considerable impact on the political milieu of the region since its political career has experienced a renewed boost. Furthermore, Salafism has emerged as a legitimate force in the country demanding al-Nahḍah to redefine its role and strategy. While in power al-Nahḍah faced multifarious political, social and economic challenges that compelled it to devise new strategies and policies to suit the changing sociopolitical climate. In addition to exploring post-revolution transitions and transformations in Tunisia, this paper focuses on Ḥizb al-Nahḍah, the issues and challenges it encountered while in power, and those that lie ahead.
Maintenance and differentiation of human ES cells on polyvinylidene fluoride scaffolds immobilized with a vitronectin‐derived peptide

Field: Materials Science (Physical Sciences)

Abstract Polyvinylidene fluoride (PVDF) is biocompatible, easy to fabricate, and has piezoelectric properties; it has been used for many biomedical applications including stem cell engineering. However, long‐term cultivation of human embryonic stem cells (hESCs) and their differentiation toward cardiac lineages on PVDF have not been investigated. Herein, PVDF nanoscaled membrane scaffolds were fabricated by electrospinning; a vitronectin‐derived peptide‐mussel adhesive protein fusion (VNm) was immobilized on the scaffolds. hESCs cultured on the VNm‐coated PVDF scaffold (VNm–PVDF scaffold) were stably expanded for more than 10 passages while maintaining the expression of pluripotency markers and genomic integrity. Under cardiac differentiation conditions, hESCs on the VNm–PVDF scaffold generated more spontaneously beating colonies and showed the upregulation of cardiac‐related genes, compared with those cultured on Matrigel and VNm alone. Thus, VNm–PVDF scaffolds may be suitable for the long‐term culture of hESCs and their differentiation into cardiac cells, thus expanding their application in regenerative medicine.
The Ceratitis capitata homologue of the Drosophila sex-determining gene Sex-lethal is structurally conserved, but not sex-specifically regulated

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

ABSTRACT In Drosophila, Sxl functions as a binary switch in sex determination. Under the control of the primary sex-determining signal, it produces functional protein only in XX animals to implement female development. Here we report that, in contrast to Drosophila, the Sxl homologue in the Medfly, Ceratitis capitata, expresses the same mRNAs and protein isoforms in both XX and XY animals irrespective of the primary sex-determining signal. Also, experiments with two inducible transgenes demonstrate that the corresponding Ceratitis SXL product has no significant sex-transforming effects when expressed in Drosophila. Similar results have been obtained for the Sxl homologue of Musca domestica (Meise, M., Hilfiker-Kleiner, D., Brunner, C., Dübendorfer, A., Nöthiger, R. and Bopp, D. (1998) Development 125, 1487-1494). Our findings suggest that Sxl acquired its master regulatory role in sex determination during evolution of the Acalyptratae group, most probably after phylogenetic divergence of the genus Drosophila from other genera of this group.
Lucerne, phalaris, and wallaby grass in short-term pasture phases in two eastern Australian wheatbelt environments. 2. Effect of perennial density and species on subterranean clover populations and the relative success of 3 clover cultivars of different maturity

Field: Agricultural and Biological Sciences (Life Sciences)

The effect of the density of 3 perennial species, phalaris (Phalaris aquatica L.), wallaby grass (Austrodanthonia richardsonii Kunth), and lucerne (Medicago sativa L.), on seed set, regeneration, and the relative competitiveness of 3 cultivars of subterranean clover (Trifolium subterraneum L.) was examined in 2 environments in the south-eastern Australian wheatbelt. Seed yields of subterranean clover were inversely related to perennial density at both sites over the first 2 years, the relationship varying with perennial species. Phalaris depressed the seed yield of clover more than lucerne and wallaby grass in the second and third year at equivalent densities. Clover seed yield was positively related to clover herbage yield in late spring at both sites, and inversely related to perennial herbage yield. Clover seed yield displayed an increasing linear relationship with the proportion of light reaching the clover understorey in spring, which in turn was inversely related to perennial density and perennial herbage yield. Clover seedling regeneration in mixed swards in autumn was positively related to the size of the summer seed bank, but negatively related to perennial density. Clover seedling survival following a premature germination at Kamarah was inversely correlated to the density of phalaris and lucerne in the sward. The relative competitiveness of the 3 subterranean clover cultivars varied between sites, with climatic conditions (rainfall and growing-season length) having a greater effect on the relative cultivar performance than companion perennial species or density. The later maturing subterranean clover cv. Goulburn became the dominant cultivar at the wetter site, constituting 72% of the seed bank, but declined to only 3–8% of the seed bank at the drier site. The proportion of the early flowering cultivar Dalkeith in the seed bank increased over time at the drier site and was highest (53%) in plots with the highest perennial density. We concluded that although perennial pasture species will depress clover seed yield and subsequent regeneration, these effects could be minimised by reducing perennial densities and exploiting variations in competitiveness between perennial species as identified in this study. Sowing earlier maturing subterranean clover cultivars would only be an advantage in increasing clover content in low-rainfall environments. The findings suggest that clover seed reserves and regeneration could also be increased by using grazing management to reduce the level of shading of clover by perennials, a factor associated with reduced clover seed yield.
Ways of Regulating Migration Processes in the Russian Federation

Field: Social Sciences (Social Sciences)

It is generally known that our nation is currently experiencing a profound demographic crisis, owing to the increased mortality rate and decline in the birth rate. Only migration, which replenishes the natural losses of the population, can act as an alternative to this process. Russia is currently at a crossroads, the old policy of population distribution has become outmoded, but a new market-based one has not yet taken on visible outlines. As a result, the migrational aspirations of the population cannot be clarified. Forced migration has unfortunately become a typical phenomenon of contemporary Russia. The break-up of the USSR worsened the economic and domestic political climate in the former union republics. The lack of protections for the basic rights and guarantees of citizens has opened up the possibility of discrimination against individuals of nonindigenous origin.
Original Article Validation of the International Index of Erectile Function (IIFE) for Use in Brazil

Field: Medicine (Health Sciences)

Background: The International Index of Erectile Function has been proposed as a method for assessing sexual function assisting the diagnosis and classification of erectile dysfunction. However, IIEF was not validated for the Portuguese language. Objective: Validate the International Index of Erectile Function in patients with cardiopulmonary and metabolic diseases. Methods: The sample consisted of 108 participants of to Cardiopulmonary and Metabolic program Rehabilitation (CPMR) in southern Brazil. The clarity assessment of the instrument was performed using a scale ranging from zero to 10. The construct validity was carried out by confirmatory factor analysis (KMO = 0.85; Barllet p &lt; 0.001), internal consistency by Cronbach’s alpha and reproducibility and interrater reliability via the test retest method. Results: The items were considered very clear with averages superior to 9. The internal consistency resulted in 0.89. The majority of items related correctly with their domains, with exception of three questions from sexual satisfaction domain, and one from erectile function. All items showed excellent stability of measure and substantial to almost perfect agreement. Conclusion: The present study showed that the IIEF is valid and reliable for use in participants of a cardiopulmonary and metabolic rehabilitation program. (Arq Bras Cardiol. 2013;101(2):176-182)
Dangers of Radio-translucent Dental Plates

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Abstract

Transcription factors respond to multi-level stimuli and co-occupy promoter regions of target genes to activate RNA polymerase (RNAP) in a cooperative manner. To decipher the molecular mechanism, here we report two cryo-electron microscopy structures of Anabaena transcription activation complexes (TACs): NtcA-TAC composed of RNAP holoenzyme, promoter and a global activator NtcA, and NtcA-NtcB-TAC comprising an extra context-specific regulator NtcB. Structural analysis showed that NtcA binding makes the promoter DNA bend by ∼50º, which facilitates RNAP to contact NtcB at the distal upstream NtcB box. The sequential binding of NtcA and NtcB induces looping back of promoter DNA towards RNAP, enabling the assembly of a fully activated TAC bound with two activators. Together with biochemical assays, we propose a ‘DNA looping’ mechanism of cooperative transcription activation in bacteria.

THERMOPHILIC AMINOPEPTIDASES FROM BAC.STEAROTHERMOPHILUS

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

The thermophilic (thermostable) aminopeptidase I (AP I) can be converted into a stable apoenzyme by dialysis at pH 5.6 against EDTA. Presumably during the formation of the apoenzyme (pH 5.6) the removal of the Co 2+ and the alteration of the pH (from 7.2 to 5.6) increase the negative charge of the enzyme molecule (gel electrophoresis), which presumably causes a change in conformation and an increase in the number of accessible carboxyl groups. The ORD remains unaltered during this process. The AP I in Co 2‐ ‐free buffer and the apoenzyme are thermolabile at pH 5.6 and pH 8.1, respectively, which reveals the importance of the role played by the Co 2+ ions bound at the active site or by additional Co 2‐ ions bound at other points of the molecule with regard to the thermostability of the native AP I. Upon recombination with Co 2+ , an active aminopeptidase (AP I*) is obtained from the apoenzyme (pH 5.6). The recombined AP I*, however, can no longer be stained to the same extent as the native AP I in gel electrophoresis with Coomassie Brilliant Blue R 250 or with Amido Black 10B. AP I has an &#x004d;̄app of 400,000 = 45,000 (sedimentation equilibrium) and an M S,D , of 395,000 ± 30,000 (S 20,W, C O =‐ 16.5 and D 20,W,C=O = 3.9‐10 ‐7 ). The inactive apoenzyme displays a slightly reduced S 20,W, of 13.8, while the ORD is the same as for active AP I. In 8M urea and 10 ‐2 M EDTA at pH 5.6, AP I decomposes into subunits (M S,D ‐36,500 ± 4,000; S 20,W ‐ 1.95 ± 0.1; D 20,W = 5.0 ± 0.25‐10 ‐7 ). The “helical” content of 22% in native AP I decreases to 6% in the process. AP I is largely stable in 8M urea (peptide hydrolysis activity and ORD are unchanged; slight decrease in S 20,W = 14.4; the inhibition of LNA hydrolysis by 8M urea is fully reversible). The activity of the AP I preparations depends on the conditions of the procedures for isolating the enzyme. The activation of AP I at higher temperature is dependent on Co 2‐ ion concentration and on temperature. Recombined AP I* (from apoenzyme) is not activatable. The activation of AP I at 80° reaches a maximum after 30 min.
The risk of women in Manitoba acquiring pelvic inflammatory disease from one or more episodes of genital Chlamydia trachomatis or Neisseria gonorrhoeae infections

Field: Medicine (Health Sciences)

The association between being infected with the sexually transmitted infections (STIs), Chlamydia trachomatis or Neisseria gonorrhoeae and developing pelvic inflammatory disease (PID) is supported in the literature. Research also demonstrates an association between repeat infections with chlamydia or gonorrhea and acquiring PID. While there is some information from Canada on this topic, the majority of the research is from the United States and abroad. Additionally, there are few studies that have been able to examine the risk of acquiring PID utilizing a prospective study design. The purpose of this study is to identify the risk of women in Manitoba acquiring PID from one or more episodes of genital chlamydia or gonorrhea. The length of time following a genital chlamydial or gonococcal infection where PID develops is explored. Obtaining information on the risks of acquiring PID, among women in Manitoba with genital chlamydia or gonorrhea, has important policy implications such as early detection and screening of STIs, treatment procedures, partner notification and contact tracing. A surveillance system framework was used to guide the study. The data were acquired by linking administrative databases from Cadham Provincial Laboratory and Manitoba Health. Three cohorts of women were chosen, based on their history of testing positive or negative for STIs. Quantitative data analysis was completed through the use of the Statistical Analysis Software (SAS) program. Descriptive statistics and frequency distributions were completed for each variable to become familiar with the data. Since this is a cohort study, incidence rates and measures of association, such as the relative risk, were completed. Tests of statistical significance were also calculated. Study findings indicate that l5 - 24 year old women, in Manitoba with documented infections of genital...

Avian Lymphomatosis. VI. A Virus of Unusual Potency and Pathogenicity

Field: Veterinary (Health Sciences)

It is well established that avian lymphomatosis is of viral etiology. The shortcomings of viral isolates used experimentally have been that they require long incubation periods and special genetic lines of chickens, and are of low or inconsistent pathogenicity. Burmester et al. (1) demonstrated the presence of a filterable agent, designated as RPL-12 virus, in an avian lymphoid tumor. The response of line 15 chickens to graded doses of this virus demonstrated an infective range from a low of 55.5% in a low-dose lot to a high of 90.1% in a highdose lot and the average age at death in the same lots was respectively 128.2 and 55.6 days (2). The manifestations of cellular and cell-free preparations of JM lymphomatosis virus in Cornell's S-line chickens have been reported by Sevoian et al. (5,6,7,8). The response was measured by mortality, and the presence of gross lesions in the survivors during a 3-week experimental period. The mortality rarely exceeded 10% during this period, and, more often, none occurred. Therefore, virus titers of cellular preparations were expressed as the 50% infective dose and ranged
AN IMPROVED METHOD FOR EVALUATION OF NEPHROTOXICITY BY ASSAY OF URINARY beta N -ACETYL--D-GLUCOSAMINIDASE (NAG) ACTIVITY

Field: Pharmacology, Toxicology and Pharmaceutics (Life Sciences)

Reaction conditions of N-acetyl- beta -D-glucosam inidase (EC 3.2.1.30;NAG) determination in untreated urine samples were studied, using 4-nitrophenyl-Nacetyl- beta -D-glucosaminide (PNP-NAG) as substrate. Final concentrations of 8 mm ol of PNP-NAG, 25 m mol of acetate, or 100 mm ol of citrate (pH 4.80 at 37 C) per liter and a sample/ reagent volum e ratio of 1/ 8 were found to be optimum. The within-run and between-run precision was excellent, with CVs averaging 2.67 and 4.55%, respectively. Reference values for urinary NAG activity assayed by this m ethod were established for untimed hum an urine specimens from 206 healthy subjects. The normal reference interval (mean- 1SD) was 0.15-15.05 (4.51 - 3.02) U per gram creatinine. By this method, urinary NAG activity can be m easured over a wide range (up to 200 U/ L) in untreated urine samples with high sensitivity. Urine samples need no pretreatment, and two reagent solutions are enough for measurement of NAG activity. The method is thus suitable for use with various automated analyzers. Finally, this m ethod requires only to 25 muL of untreated urine. Therefore, it is appropriate for evaluating nephrotoxicity in hum an (especially neonates and infants) and sm all animal models by assay of urinary NAG activity.
CINNABAR DEPOSITION IN SUBMARINE COASTAL HYDROTHERMAL VENTS, PACIFIC MARGIN OF CENTRAL MEXICO

Field: Earth and Planetary Sciences (Physical Sciences)

Cinnabar deposition was observed in submarine hydrothermal vents at about 10 m depth in the Punta Mita area in western Mexico. The vents occur in basaltic rocks and discharge a mixture of liquid and gas at a temperature of 85°C. Tertiary ignimbrites, basaltic lava flows, and mafic intrusions crop out in Punta Mita; however, at present there is no volcanic activity in the area, and the hydrothermal vents do not possess characteristics compatible with a magmatic heat source. The water discharged by the vents is more dilute than seawater, and precious and base metal contents are below detection limits. The gas is composed mostly of nitrogen and methane, and it contains only trace amounts of He, Ar, H2, CO2, H2S, and O2.

Deposits of carbonates (calcite and aragonite), sulfides (pyrite, cinnabar, minor thallium sulfide, and galena), sulfates (barite), and phosphates (carbonate-hydroxyl apatite) were observed. Cinnabar occurs in association with thallium sulfide within pyrite crusts that line the upflow channels and cover the outflow areas near the vents.

The hydrothermal activity in Punta Mita is related to deep circulation of ground water from onshore and convective heating in the high geothermal gradient of the area. The interaction of the hot water with organic matter in the layers of sedimentary rocks produces nitrogen and methane, and mercury and other elements are leached from the volcanic and sedimentary rocks. Mercury remains in solution in the thermal fluid until it reaches the sea floor.
