Segregation of DNA polynucleotide strands into sister chromatids and the use of endoreduplicated cells to track sister chromatid exchanges induced by crosslinks, alkylations, or x-ray damage.

The method of Matsumoto and Ohta [Matsumoto, K. & Ohta, T. (1992) Chromosoma 102, 60-65; Matsumoto, K. & Ohta, T. (1995) Mutat. Res. 326, 93-98] to induce large numbers of endoreduplicated Chinese hamster ovary cells has now been coupled with the fluorescence-plus-Giemsa method of Perry and Wolff [Perry, P. & Wolff, S. (1974) Nature (London) 251, 156-158] to produce harlequin endoreduplicated chromosomes that after the third round of DNA replication are composed of a chromosome with a light chromatid and a dark chromatid in close apposition to its sister chromosome containing two light chromatids. Unless the pattern is disrupted by sister chromatid exchange (SCE), the dark chromatid is always in the center, so that the order of the chromatids is light-dark light-light. The advent of this method, which permits the observation of SCEs in endoreduplicated cells, makes it possible to determine with great ease in which cell cycle an SCE occurred. This now allows us to approach several vexing questions about the induction of SCEs (genetic damage and its repair) after exposure to various types of mutagenic carcinogens. The present experiments have allowed us to observe how many cell cycles various types of lesions that are induced in DNA by a crosslinking agent, an alkylating agent, or ionizing radiation, and that are responsible for the induction of SCEs, persist before being repaired and thus lose their ability to inflict genetic damage. Other experiments with various types of mutagenic carcinogens and various types of cell lines that have defects in different DNA repair processes, such as mismatch repair, excision repair, crosslink repair, and DNA-strand-break repair, can now be carried out to determine the role of these types of repair in removing specific types of lesions.

Correlation of individual papilloma latency time with DNA adducts, 8-hydroxy-2'-deoxyguanosine, and the rate of DNA synthesis in the epidermis of mice treated with 7,12-dimethylbenz[alpha]anthracene.

The question was addressed whether the risk of cancer of an individual in a heterogeneous population can be predicted on the basis of measurable biochemical and biological variables postulated to be associated with the process of chemical carcinogenesis. Using the skin tumor model with outbred male NMRI mice, the latency time for the appearance of a papilloma was used as an indicator of the individual cancer risk. Starting at 8 weeks of age, a group of 29 mice was treated twice weekly with 20 nmol of 7,12-dimethylbenz[alpha]anthracene (DMBA) applied to back skin. The individual papilloma latency time ranged from 13.5 to 25 weeks of treatment. Two weeks after the appearance of the first papilloma in each mouse, an osmotic minipump delivering 5-bromo-2'-deoxyuridine was s.c. implanted and the mouse was killed 24 hr later. Levels of DMBA-DNA adducts, of 8-hydroxy-2'-deoxyguanosine, and various measures of the kinetics of cell division were determined in the epidermis of the treated skin area. The levels of 8-hydroxy-2'-deoxyguanosine and the fraction of cells in DNA replication (labeling index for the incorporation of 5-bromo-2'-deoxyuridine) were significantly higher in those mice that showed short latency times. On the other hand, the levels of DMBA-DNA adducts were lowest in animals with short latency times. The latter finding was rather unexpected but can be explained as a consequence of the inverse correlation seen for the labeling index: with each round of cell division, the adduct concentration is reduced to 50% because the new DNA strand is free of DMBA adducts until the next treatment. Under the conditions of this bioassay, therefore, oxygen radical-related genotoxicity and the rate of cell division, rather than levels of carcinogen-DNA adducts, were found to be of predictive value as indicators of an individual cancer risk.

Emergent Brazil and the Curse of the ‘Hen’s Flight’. CEPS Working Document No. 379, 27 February 2013

The ‘Emergent Brazil’ growth model is reaching its limits. Its main engines have been slowing significantly since the beginning of the global financial and economic crisis. Even its much-praised predictable macroeconomic policy has been eroded by political interference. Inflationary pressures are growing and GDP performance is anaemic. As ominous, Brazil cannot compensate for its domestic deficiencies with an export drive. Commodity exports are suffering with the world economic slow-down and the manufacturing industries’ competitiveness is in sharp decline. Brazil has put all its trade negotiation eggs into the South American and WTO baskets, and now its export market share is threatened by the Doha Round paralysis, the Latin American Alianza del Pacífico, and the US-led initiatives for a Trans-Pacific Partnership and a trade and investment agreement with the EU. Paradoxically, this alarming situation opens a window of opportunity. There is a mounting national consensus on the need to tackle head-on the country’s and its industries’ lack of competitiveness. That means finding a solution to the much-decried ‘Brazil Cost’ and stimulating private-sector investment. It also entails an aggressive trade-negotiating stance in order to secure better access to foreign markets and to foster more competition in the domestic one. The most promising near-term goal would be the conclusion of the EU–Mercosur trade talks. A scenario to overcome the paralysis of these negotiations could trail two parallel paths: bilateral EU–Brazil agreements on ‘anything but trade’ combined with a sequencing of the EU–Mercosur talks where each member of the South American bloc could adopt faster or slower liberalisation commitments and schedules.

Reducing task’s redundancy – the strategy of Faculty of Pharmacy Library to centralize all scientific research

Introduction – Based on a previous project of University of Lisbon (UL) – a Bibliometric Benchmarking Analysis of University of Lisbon, for the period of 2000-2009 – a database was created to support research information (ULSR). However this system was not integrated with other existing systems at University, as the UL Libraries Integrated System (SIBUL) and the Repository of University of Lisbon (Repositório.UL). Since libraries were called to be part of the process, the Faculty of Pharmacy Library’ team felt that it was very important to get all systems connected or, at least, to use that data in the library systems. Objectives – The main goals were to centralize all the scientific research produced at Faculty of Pharmacy, made it available to the entire Faculty, involve researchers and library team, capitalize and reinforce team work with the integration of several distinct projects and reducing tasks’ redundancy. Methods – Our basis was the imported data collection from the ISI Web of Science (WoS), for the period of 2000-2009, into ULSR. All the researchers and indexed publications at WoS, were identified. A first validation to identify all the researchers and their affiliation (university, faculty, department and unit) was done. The final validation was done by each researcher. In a second round, concerning the same period, all Pharmacy Faculty researchers identified their published scientific work in other databases/resources (NOT WoS). To our strategy, it was important to get all the references and essential/critical to relate them with the correspondent digital objects. To each researcher previously identified, was requested to register all their references of the ‘NOT WoS’ published works, at ULSR. At the same time, they should submit all PDF files (for both WoS and NOT WoS works) in a personal area of the Web server. This effort enabled us to do a more reliable validation and prepare the data and metadata to be imported to Repository and to Library Catalogue. Results – 558 documents related with 122 researchers, were added into ULSR. 1378 bibliographic records (WoS + NOT WoS) were converted into UNIMARC and Dublin Core formats. All records were integrated in the catalogue and repository. Conclusions – Although different strategies could be adopted, according to each library team, we intend to share this experience and give some tips of what could be done and how Faculty of Pharmacy created and implemented her strategy.

The war of nerves with Iran - consequences for the South Caucasus and Russia. OSW Commentary No. 75, 2012-04-25

Tensions over Iran’s nuclear programme have risen considerably in recent months. This has been visible in numerous threats of – and much speculation about – an imminent Israeli (and US) attack on Iran’s nuclear installations. In this context, the support for the attacks that the countries of the South Caucasus (and Azerbaijan in particular) could provide has been the subject of lively debate, as has been the prospect of a Russian political and military offensive in the Caucasus in response to the attacks on Iran. It seems that the ongoing war campaign in the media has been aimed primarily at putting pressure on Iran and the international community to find a political solution to the Iranian problem. This also applies to the Caucasus’s involvement in the campaign. Given the outcome of the Istanbul round of talks on a political solution to the Iranian issue (14 April), which warrants moderate optimism, the threat of a conflict now appears more distant and this also indirectly proves the effectiveness of the campaign. The war of nerves with Iran, however, is already now actually affecting the stability of the Southern Caucasus. While it seems that Azerbaijan is not Israel’s partner in the preparations to attacks, and that there is no real link between the Iranian problem and the ongoing and planned movements of Russian troops in the Caucasus, the tensions between Iran and Azerbaijan are indeed high. Moreover, the global image of the Caucasus is deteriorating, the USA’s position in the region is becoming more complicated, and Russia’s room for manoeuvre is expanding.

Localizing EU Gender Policy: The Diffusion of Gender Mainstreaming across Feminist Movements in Eastern Germany. CES Germany & Europe Working Papers, No. 08.1, June, 2008

Gender mainstreaming emerged in the mid-1990s as an innovative and controversial policy tool for reducing gender inequalities. The European Union seeks to propagate the practice of gender mainstreaming both within EU institutions and among member states. Feminist scholars and policy elites discuss and debate gender main-streaming widely, but have yet to consider how local feminist activists, who could play a central role in diffusing gender mainstreaming, understand, interpret and respond to this agenda. This paper examines whether and why local feminist movements in two cities in eastern Germany adopt gender mainstreaming. Consideration of the characteristics of the contexts in which local feminist movements are embedded clarifies the conditions under which social movements rally round new policy paradigms.

A national e-Delphi towards the measurement of safe medication practices in Portuguese hospitals

Objectives To determine the face and content validity of items for measuring safe medication practices in Portuguese hospitals. Methods 128 items were drafted from content analysis of existing questionnaires and the literature, employing preferred terms of the WHO International Classification for Patient Safety (Portuguese version). A two-round e-Delphi was convened, using a purposive multidisciplinary panel. Hospital-based experts were asked to rate the relevance of items on a 7-point Likert scale and to comment on their clarity and completeness. Results The response rate was similar in both rounds (70.3% and 73.4%, respectively). In the first round 91/128 (71.1%) items reached the predefined level of positive consensus. In the second round 23 additional items reached positive consensus, as well as seven items newly derived by the panel. Conclusions Most items have face and content validity, indicating relevance and clarity, and can be included in a future questionnaire for measuring safe medication practices in Portuguese hospitals.

(Table 2) Ice rafted debris abundance and accumulation rate, sedimentation rate and dry bulk density of bottom sediments from the Sea of Okhotsk

Oxygen isotope records, radiocarbon AMS data, carbonate and opal stratigraphy, sediment magnetic susceptibility, tephrachronology, and paleontological results were used to obtain detailed sediment stratigraphy and an age model for the studied cores. For studying sea-ice sedimentation an analysis of lithogenic grain number in >0.15 mm grain size fraction of bottom sediments was carried out. For quantitative estimation of intensity ice-rafting debris sedimentation number of IRD particles per sq cm per ka was calculated. Obtained results allowed to plot IRD AR distribution for the first oxygen isotope stage (0-12.5 14C ka, 14C) and for the second stage (12.5-24 14C ka). The first stage was subdivided into the latest deglaciation and the beginning of Holocene (6-12.5 14C ka) (transitive period), when the sea level was changing significantly, and the second part of Holocene (0-6 14C ka), when climate conditions and the sea level were similar to modern estimates. Data clearly show strong increase in ice formation in the glacial Sea of Okhotsk and its extent in the middle part of the sea. Average annual duration of ice coverage during glaciation was longer than that for interglaciation. However the sea ice cover was not continuous all the year round and disappeared in summer time except the far northwestern part of the sea.
