Conversion and Colonial History in Icíar Bollaín’s También la lluvia (2010)

This study concerns the representation of colonial Latin American history and the characterisation of Daniel/Hatuey in the 2010 film-about-a-film También la lluvia. A metacinematic work comprising historical study and political commentary, También la lluvia has received mixed critical reactions regarding its portrayal of the historical and social inequalities it analyses. This article examines the ambiguous nature of the work by analysing the motif of conversion. It argues that, by foregrounding the contemporary conversion story of Costa, the film sacrifices both nuanced historical attention to the colonial past it dramatises and sustained development of one of its apparently central characters: Daniel/Hatuey, who is repeatedly converted into narrative and symbolic figures of secondary prominence, despite their importance to the development and legibility of the work as a whole

Use of low-resolution CT scans for construction of detailed geometric models of mandibles with and without teeth

Detailed geometric models of a mandible can improve the accuracy of computer simulations. However, cost, time and qualified labor available for their construction may hinder or delay the task. The purpose of this article is to describe a technique for reconstructing a mandible with and without teeth from clinical CT scans of low resolution. The method allows modeling geometric details usually difficult to reconstruct with these scans, such as the periodontal ligament. The models of a toothless and toothed mandible resulting from the process are available online for non-commercial use. The models can be used in various fields such as orthodontics, implantology, orthopedics and traumatology as presented or as a basis for simulations

Mice Lacking Endoglin in Macrophages Show an Impaired Immune Response

Endoglin is an auxiliary receptor for members of the TGF-β superfamily and plays an important role in the homeostasis of the vessel wall. Mutations in endoglin gene (ENG) or in the closely related TGF-β receptor type I ACVRL1/ALK1 are responsible for a rare dominant vascular dysplasia, the Hereditary Hemorrhagic Telangiectasia (HHT), or Rendu-Osler-Weber syndrome. Endoglin is also expressed in human macrophages, but its role in macrophage function remains unknown. In this work, we show that endoglin expression is triggered during the monocyte-macrophage differentiation process, both in vitro and during the in vivo differentiation of blood monocytes recruited to foci of inflammation in wild-type C57BL/6 mice. To analyze the role of endoglin in macrophages in vivo, an endoglin myeloid lineage specific knock-out mouse line (Engfl/flLysMCre) was generated. These mice show a predisposition to develop spontaneous infections by opportunistic bacteria. Engfl/flLysMCre mice also display increased survival following LPS-induced peritonitis, suggesting a delayed immune response. Phagocytic activity is impaired in peritoneal macrophages, altering one of the main functions of macrophages which contributes to the initiation of the immune response. We also observed altered expression of TGF-β1 target genes in endoglin deficient peritoneal macrophages. Overall, the altered immune activity of endoglin deficient macrophages could help to explain the higher rate of infectious diseases seen in HHT1 patientsThis work was funded by: Ministerio de Economía y Competitividad of Spain (SAF2011- 23475 to LMB; SAF2013-43421-R and SAF2010-19222 to CB; and Centro de Investigación Biomédica en Red de Enfermedades Raras (CIBERER), and FEDER funds.

The serine protease stratum corneum chymotryptic enzyme (kallikrein 7) is highly overexpressed in squamous cervical cancer cells.

OBJECTIVE: To determine whether the Stratum Corneum Chymotryptic Enzyme (SCCE), a novel serine protease known to contribute to the cell shedding process by catalyzing the degradation of intercellular cohesive structures at the skin surface, is overexpressed in human cervical tumors. METHODS: SCCE expression was evaluated in 18 cervical cancer cell lines (i.e., 10 primary and 8 established cell lines) as well as in 8 normal cervical keratinocyte cultures by RT-PCR. In addition, SCCE expression was evaluated by immunohistochemistry on paraffin-embedded tumor tissue. RESULTS: Normal cervical keratinocytes did not express SCCE. In contrast, 50% of the primary and 50% of the established cervical cancer cell lines expressed SCCE by RT-PCR. Eighty percent (i.e., four of five) of primary squamous cervical tumors and 20% (i.e., one of five) of primary adenocarcinomas expressed SCCE. Five out of five (100%) of the patients harboring SCCE-positive tumors were found to have metastatic involvement of the pelvic tumor draining lymph nodes. Immunohistochemistry staining of paraffin-embedded cervical cancer specimens confirmed SCCE expression in tumor cells and its absence on normal cervical epithelial cells. CONCLUSION: Squamous cervical cancer expressed high levels of SCCE, suggesting that this protease may play an important role in invasion and metastasis. Because SCCE appears only in abundance in tumor tissue and contains a secretion signal sequence, suggesting that SCCE is secreted, it may prove to be a useful diagnostic/prognostic tool for the detection of metastatic or recurrent disease or as a novel molecular target for cervical cancer therapy

The novel serine protease tumor-associated differentially expressed gene-14 (KLK8/Neuropsin/Ovasin) is highly overexpressed in cervical cancer.

OBJECTIVE: Serine proteases are redundant enzymes implicated in the extracellular modulation required for tumor growth and invasion. Tumor-associated differentially expressed gene-14 (TADG-14) is a novel transmembrane serine protease recently reported by our group to be highly overexpressed in ovarian carcinomas. The goal of this study was to investigate the frequency of expression of the TADG-14 gene in human cervical tumors. STUDY DESIGN: TADG-14 expression was evaluated in 19 cervical cancer cell lines (11 primary and 8 established cell lines) as well as in 8 normal cervical keratinocyte cultures by reverse transcriptase polymerase chain reaction. In addition, to validate gene expression data at the protein level, TADG-14 expression was evaluated by immunohistochemistry on paraffin-embedded tissue from which all 11 primary tumor cell lines were established. RESULTS: TADG-14 was found to be highly expressed in 82% (9/11) primary cervical cancer cell lines and in 87% (7/8) established cervical cancer cell lines by reverse transcriptase-polymerase chain reaction. Expression of TADG-14 by primary squamous cervical tumors was 100% (6/6), whereas 60% (3/5) of primary adenocarcinomas expressed TADG-14. In contrast, none of the normal cervical keratinocyte control cultures (n=4) or flash frozen normal cervical biopsy specimens (n=4) expressed TADG-14. Immunohistochemistry staining of paraffin-embedded cervical cancer specimens confirmed TADG-14 expression in tumor cells and its absence on normal cervical epithelial cells. CONCLUSION: Cervical cancer expressed a high level of TADG-14, suggesting that this protease may play an important role in invasion and metastasis. Because TADG-14 appears only in abundance in tumor tissue and contains a secretion signal sequence, suggesting that TADG-14 is secreted, it may prove to be a useful diagnostic tool for the early detection of recurrent/persistent cervical cancer after standard treatment or as a novel molecular target for cervical cancer therapy

The novel serine protease tumor-associated differentially expressed gene-15 (matriptase/MT-SP1) is highly overexpressed in cervical carcinoma.

BACKGROUND: Tumor-associated differentially expressed gene-15 (TADG-15/matriptase/MT-SP1) is a novel transmembrane serine protease involved in numerous biologic processes, including activation of growth and angiogenic factors and degradation of extracellular matrix components. To assess the value of TADG-15 as a possible marker for tumor detection and/or as a target for therapeutic intervention, the authors investigated the frequency of expression of TADG-15 in human cervical tumors. METHODS: TADG-15 expression was evaluated in 19 cervical carcinoma cell lines (i.e., 11 primary tumor cell lines and 8 established cell lines) and in 8 normal cervical keratinocyte control cultures using reverse transcriptase-polymerase chain reaction (RT-PCR). In addition, to validate gene expression data at the protein level, TADG-15 expression was evaluated by immunohistochemistry on paraffin embedded tissue from which all 11 primary tumor cell lines were established. RESULTS: TADG-15 was expressed at high levels in 8 of 11 (73%) primary cervical carcinoma cell lines and in 6 of 8 (75%) established cervical carcinoma cell lines by RT-PCR. Expression of TADG-15 was found in 6 of 6 (100%) primary squamous cell cervical carcinomas, whereas 2 of 5 (40%) primary adenocarcinomas expressed TADG-15. In contrast, none of the normal cervical keratinocyte control cultures (n = 4) or flash-frozen normal cervical biopsy specimens (n = 4) expressed TADG-15. Immunohistochemistry staining of paraffin embedded cervical carcinoma specimens confirmed TADG-15 expression in tumor cells and its absence on normal cervical epithelial cells. CONCLUSIONS: Cervical carcinoma cells expressed high levels of TADG-15, suggesting that this protease may play an important role in invasion and metastasis. Because TADG-15 appears only in abundance in squamous tumor tissue and contains a proteolytic cleavage site, suggesting that the TADG-15 protease domain is released, it may prove to be a useful diagnostic tool for the early detection of recurrent/persistent cervical carcinoma after standard treatment or as a novel molecular target for therapy in patients with cervical carcinoma

‘People lie’: overcoming obstacles to incorporate social science research to biodiversity conservation

Mesmo com o reconhecimento da importância da interdisciplinaridade na conservação da biodiversidade, ainda há resistência em incorporar a pesquisa em ciências sociais (PCS) ao pensamento e à prática conservacionista. As razões para tal resistência podem ser resumidas em três afirmações gerais ainda comumente atribuídas à PCS: 'tem pouca utilidade' e 'menos rigor metodológico' quando comparada à pesquisa em ciências naturais e, sobretudo, é pouco confiável porque 'as pessoas mentem'. Neste ensaio, desenvolvido a partir da experiência dos participantes de uma comunidade de prática, formada por profissionais de diversas áreas e setores relacionados à conservação, e das discussões geradas nesse espaço de aprendizado coletivo, abordamos as limitações e os equívocos por trás das afirmações acima. A PCS não é menos útil na conservação e nem tem menos rigor metodológico do que a pesquisa em ciências naturais, e quando as pessoas mentem para o pesquisador o problema não está na pesquisa em si, mas na relação entre sujeito e pesquisador. Argumentamos que à medida que os conservacionistas se familiarizam com a PCS e que os princípios de equidade e justiça são incorporados aos valores e objetivos da conservação, a importância e necessidade da PCS na conservação tornam-se óbvias, e a falta de confiança entre pesquisador e sujeitos deixa de ser uma preocupação significativa. Capacitar, integrar e apoiar são nossas recomendações básicas para pesquisadores, educadores, gestores e tomadores de decisão nas áreas de conservação, ensino, publicação e financiamento, para que a PCS cumpra plenamente seu papel na conservação.Despite the acknowledged importance of interdisciplinarity in biodiversity conservation, there is still resistance to incorporate social science research (SSR) to both conservationist thinking and practice. The reasons for such a resistance can be summarized in three general statements still commonly attributed to SSR, namely: it is of 'little use' and it has 'less methodological rigor' than research in the natural sciences and, above all, it is unreliable because 'people lie'. The current essay was developed based on the experience of participants of a community of practice (formed by professionals from different fields and sectors  associated with conservation), as well as on discussions held in this space of collective learning. It addresses the limitations and misconceptions behind the aforementioned statements. SSR is not less useful in conservation and not less methodologically rigorous than research conducted in the natural sciences. When researchers are lied to, the problem does not lie on the research itself, but on the subject-researcher relationship. We herein argue that as conservationists become more familiar with SSR, and as principles like equity and justice are incorporated to conservation values and goals, both the importance and need of SSR in conservation become obvious, making the lack of trust between researcher and subjects no longer a significant concern. Increasing capacity, integrating and supporting are our basic recommendations for researchers, educators, managers and decision-makers in the conservation, teaching, publishing and funding fields, so that SSR can fully fulfill its role in conservation

The integrated action framework of Rete Natura 2000 Basilicata

Basilicata Natura 2000 network consists of 50 Sites of Community Importance (SCI) and 17 Special Protection Zones (SPZs), covering alltogether more than 17% of the regional area. This network, partially overlapping other forms of land protection, represents a valuable environmental, agricultural and cultural heritage, in which the safeguard of natural resources and landscapes has to be coupled with the needs of the local population; especially in relation to development and social welfare. The Natura 2000 project involved a panel of experts belonging to 15 different institutions, to form a steering committee with the following professional and scientific skills: vegetation, landscape, fauna, geology, agriculture, forestry, sea, architecture and planning, territorial analysis and representation. Along the 4 years project, the steering committee designed and coordinated the activities of over 150 professionals, mostly from Basilicata, who carried out field surveys and data analysis aimed at assessing the environmental conditions in the SCI and SPZs, proposing measures and plans, implementing thematic databases. SCI/SPZ management plans, by themselves, may not be sufficient to fulfill the requirements of an effective environmental policy, which has to go along with the awareness of people, citizens and local administrators about the instances of a sustainable policy. For this reason, the activities of surveying and management have been coupled with a communication project that involves all the experts and a relevant part of professionals who participated to the Natura 2000 project. The communication activity implies the use and the creation of several tools (publishing, video, websites, meetings, photo contests, social networks ...) targeted to different groups: policy makers (local, regional, national, European ), organizations, citizens, schools, farmers, small and medium enterprises (www.natura2000basilicata.it). A further goal is to feature the environmental highlights of Basilicata which are linked to a specific and often surprising integration of an ancient human presence with the natural elements, and the role performed by the traditional farming activities in the maintenance of ecosystem dynamics and services (in particular with agriculture). In fact, a good number of Natura 2000 sites can be considered High Nature Value Farmlands (HNVF, sensu E. Andersen, 2003), in which a virtuous relationship was established a long time ago between traditional practices and the environment itself. In this context, it combines the convergence between the activities carried on the Natura 2000 network and the project Agrival (http://utagri.enea.it/projects/agrival), a research project led by ENEA in Val d'Agri, in order to experimentally contribute to the methodology for the identification of the High Nature Value Farmlands and make them cohabit with the other economic activities in the local context. The process started with the project Basilicata Natura 2000 Network is therefore an interesting methodological model that, in coherence with the financial planning of the European Community for the period 2014-2020 (Brussels, 12.12.2011, COMM. 874) puts together projects on environmental issues to boost the meeting of agricultural, environmental, cultural and productive policies, fostered by the EC, and enhancing the implementation of the "Prioritized Actions Frameworks" (PAF), pointed out by the European Commission as the optimal tools for the management of Natura 2000 networks

Palbociclib in combination with endocrine therapy versus capecitabine in hormonal receptor-positive, human epidermal growth factor 2-negative, aromatase inhibitor-resistant metastatic breast cancer: a phase III randomised controlled trial—PEARL

Background: Palbociclib plus endocrine therapy (ET) is the standard treatment of hormone receptor-positive and human epidermal growth factor receptor 2-negative, metastatic breast cancer (MBC). However, its efficacy has not been compared with that of chemotherapy in a phase III trial. Patients and methods: PEARL is a multicentre, phase III randomised study in which patients with aromatase inhibitor (AI)-resistant MBC were included in two consecutive cohorts. In cohort 1, patients were randomised 1 : 1 to palbociclib plus exemestane or capecitabine. On discovering new evidence about estrogen receptor-1 (ESR1) mutations inducing resistance to AIs, the trial was amended to include cohort 2, in which patients were randomised 1 : 1 between palbociclib plus fulvestrant and capecitabine. The stratification criteria were disease site, prior sensitivity to ET, prior chemotherapy for MBC, and country of origin. Co-primary endpoints were progression-free survival (PFS) in cohort 2 and in wild-type ESR1 patients (cohort 1 + cohort 2). ESR1 hotspot mutations were analysed in baseline circulating tumour DNA. Results: From March 2014 to July 2018, 296 and 305 patients were included in cohort 1 and cohort 2, respectively. Palbociclib plus ET was not superior to capecitabine in both cohort 2 [median PFS: 7.5 versus 10.0 months; adjusted hazard ratio (aHR): 1.13; 95% confidence interval (CI): 0.85-1.50] and wild-type ESR1 patients (median PFS: 8.0 versus 10.6 months; aHR: 1.11; 95% CI: 0.87-1.41). The most frequent grade 3-4 toxicities with palbociclib plus exemestane, palbociclib plus fulvestrant and capecitabine, respectively, were neutropenia (57.4%, 55.7% and 5.5%), hand/foot syndrome (0%, 0% and 23.5%), and diarrhoea (1.3%, 1.3% and 7.6%). Palbociclib plus ET offered better quality of life (aHR for time to deterioration of global health status: 0.67; 95% CI: 0.53-0.85). Conclusions: There was no statistical superiority of palbociclib plus ET over capecitabine with respect to PFS in MBC patients resistant to AIs. Palbociclib plus ET showed a better safety profile and improved quality of life
