description: Failure of radiotherapy for treatment of neoplastic disease can be due to selection of radioresistant S-phase cells within tumours. However, S-phase cells can be targeted with a type-1 DNA topoisomerase inhibitor, camptothecin (CPT) or one of its analogs. The first objective of this study was to understand the mechanism of cellular death of human tumour and normal cells following treatment to CPT and single dose (nonfractionated) X-radiation. We found that necrotic cell death was more important than apoptotic cell death during concurrent CPT and radiation treatment in melanoma (SkMel-3) cells, but not in normal fibroblast (AG1522) cells. Further experiments involving fractionated X-radiation pre-treatment gave rise to the presence of radioresistant cells in the human tumour colorectal cell line (HCT116). Therefore, the second objective of this study was to assess whether the radioresistant cells occurred by selection or adaptation to the X-radiation treatment. We discovered that the resistant subpopulation of cells surviving a previous fractionated irradiation exposure was likely due to the selection of a radioresistant subpopulation, whereas the radiationsensitive clone manifested a potential inducible radiation response. The third objective was to produce a model system for distinguishing the genetic factors that may be involved in the radiosensitive or radioresistant phenotype. To this end, a set of untreated genetically-related human cell clones of varying radioresponses, with non-overlapping drug sensitivities, were generated from the HCT116 cell line, suggesting the presence of clonal heterogeneity and providing an excellent model. Lastly, using the clones derived from objective 3, the fourth objective was to exploit this model system and determine the genetic basis of radiosensitivity. To do this, we used human cDNA microarrays containing 19,200 ESTs and verified these gene expression changes with Q-PCR. Of a number of genes identified by the array, only spermidine/spermine N1-acetyltransferase (SSAT), an enzyme that catabolizes radioprotective polyamines had a known potential link to radiosensitivity. Our findings establish the potential importance of intrinsic gene expression in radioresponsiveness, and the identification of SSAT as a possible modulator of radiosensitivity, providing a potential tool for understanding and predicting X-radiation response.

description: Lack of cooling comfort adversely influences the health of endurance cycling athletes, especially those living in developing tropical countries. Existing cooling solutions have targeted athletes in developed and non-tropical regions. Hence, this research investigates how to develop low-cost cooling sportswear to enhance the cooling comfort of those disadvantaged athletes. Several sportswear prototypes were co-designed and tested with endurance athletes in Sri Lanka to identify the considerations for cooling sportswear design. This research proposes applying contextual factors (economy, culture, and climate) in the FEA (Functional, Expressive and Aesthetic) apparel design model to investigate the needs of the target athletes.

description: AbstractMicrowave photonics is a remarkably powerful system for quantum simulation and technologies, but its integration in superconducting circuits, superior in many aspects, is constrained by the long wavelengths and impedance mismatches in this platform. We introduce a solution to these difficulties via compact networks of high-kinetic inductance microstrip waveguides and coupling wires with strongly reduced phase velocities. We demonstrate broadband capabilities for superconducting microwave photonics in terms of routing, emulation and generalized linear and nonlinear networks.

A use case driven validation framework and case study.

Publisher: name: Université d'Ottawa / University of Ottawa
Year: 1998
Subjects: subject: Computer Science.

description: In this thesis we propose a use case driven strategy for validating software systems which are built using an incremental development process. We use the Real-time Object Oriented Modeling (ROOM) development process as an example. Our technique supports validation activities whereby a partially built system is executed and tested against some desired behaviour derived from the requirements, before further refinement is made. To represent the desired behaviour, we propose a new notation called Use Case Trees (UCT), which is derived from the Tree and Tabular Combined Notation (TTCN). In UCT several scenarios can be compacted into a single use case. Each scenario can be represented by a Message Sequence Chart (MSC). We built a tool to automatically generate selected MSCs from a UCT. The generated MSCs are used to drive the system, thus checking whether its behaviour conforms to the requirements. This validation strategy is cost-efficient as it helps to catch errors at an early stage of system development.

description: Es gibt Phänomene in der Wirtschaft, die in der wissenschaftlichen Literatur gerne und häufig beforscht und von Experten in der Praxis nahezu branchenübergreifend bestätigt werden: z. B. steigender Wettbewerbsdruck durch Globalisierung, schrumpfende Produktlebenszyklen verbunden mit einem schnelleren Übergang in die Commodity-Phase und damit einhergehender Druck auf die Entwicklungszeiten, steigender technologischer Wandel in Geschwindigkeit und Ausmaß, zunehmend geforderte Marktnähe von technologieintensiven Unternehmen. Ansätze in der Literatur, diesen Herausforderungen zu begegnen, gibt es viele. Das ITOP berücksichtigt die Vielfalt der Unternehmen und hat einen Ansatz entwickelt, der es zulässt, ein unternehmensspezifisches Technologiemanagement abzuleiten. Dabei werden branchen-, markt- und unternehmensspezifische Elemente miteinander kombiniert. Auf diese Weise wird eine systematische Vorgehensweise aufgezeigt, wie Unternehmen die zentrale Managementaufgabe des Technologiemanagements und dessen Umsetzung im eigenen Kontext kritisch hinterfragen und unternehmensspezifisch ausprägen können.

description: The birth of the first luminous sources and the ensuing epoch of reionization are best studied via the redshifted 21-cm emission line, the signature of the first two imprinting the last. In this work, we present a fully Bayesian method, HIBAYES, for extracting the faint, global (skyaveraged) 21-cm signal from the much brighter foreground emission.We showthat a simplified (but plausible) Gaussian model of the 21-cm emission from the Cosmic Dawn epoch (15 ≲ z ≲ 30), parametrized by an amplitude AHI, a frequency peak νHI and a width σHI, can be extracted even in the presence of a structured foreground frequency spectrum (parametrized as a seventh-order polynomial), provided sufficient signal-to-noise (400 h of observation with a single dipole). We apply our method to an early, 19-min-long observation from the Large aperture Experiment to detect the Dark Ages, constraining the 21-cm signal amplitude and width to be -890 < AHI < 0 mK and σHI > 6.5 MHz (corresponding to Δz > 1.9 at redshift z ≃ 20) respectively at the 95-per cent confidence level in the range 13.2 < z <27.4 (100 > ν >50 MHz).

description: Multiple pesticide residues in the environment originate from combination products with two or more active substances, from tank mixtures prepared by the farmers and from subsequent applications of pesticides in spray series. Consequently, mixtures of pesticide residues in agricultural soils are often detected long after application. To simulate the â€Ìaccumulated mixture riskâ€Ì towards earthworms resulting from a pesticide spray series for apple orchards, a model was applied considering both the dissipation of the applied pesticides over time and their individual toxicities. The model simulation for assessing the time-dependent mixture risk is applicable for several years and revealed that the â€Ìaccumulated mixture riskâ€Ì for earthworms clearly did not meet the threshold values for an acceptable risk according to the legal requirements in the EU approval procedure. Multiple pesticide residues from spray series are not yet considered in the environmental risk assessment (ERA) which is based on the application of single pesticide substances and products. We propose that the accumulation of residues during typical agricultural spray series should be included when assessing the risk of pesticides. © 2019 Elsevier B.V.

description: Background: To describe and evaluate a four step systematic approach to dissecting the recurrent laryngeal nerve (RLN) starting at the cricothyroid junction during thyroid surgery (subsequently referred to as the retrograde medial approach). Methods: All thyroidectomies completed by the senior author between August 2014 and January 2016 were retrospectively reviewed. Patients were excluded if concurrent lateral or central neck dissection was performed. A follow up period of 1 year was included. Results: Surgical photographs and illustrations demonstrate the four steps in the retrograde medial approach to dissection of the RLN in thyroid surgery. Three hundred forty-two consecutive thyroid surgeries were performed in 17 months, including 213 hemithyroidectomies, 91 total thyroidectomies, and 38 completion thyroidectomies. The rate of temporary and permanent hypocalcemia was 13% (95% confidence interval [CI]: 8–20%) and 3% (95% CI: 1–8%) respectively. The rate of temporary and permanent vocal cord palsy was 9% (95% CI: 6–12%) and 0.3% (95%CI: 0.01–2%) respectively. The median surgical times for hemithyroidectomy, total thyroidectomy, and completion thyroidectomy were 39 min (Interquartile range [IQR]: 33–47 min), 48 min (IQR: 40–60 min), and 40 min (IQR: 35–51 min) respectively. 1% of cases required conversion to an alternative surgical approach. Conclusion: In a tertiary endocrine head and neck practice, the routine use of the retrograde medial approach to RLN dissection is safe and results in a short operative time, and a low conversion rate to other RLN dissection approaches.

description: Blooms of toxic cyanobacteria in freshwater ecosystems have received considerable attention in recent years, but their occurrence and potential importance at the land-sea interface has not been widely recognized. Here we present the results of a survey of discrete samples conducted in more than fifty brackish water sites along the coastline of southern California. Our objectives were to characterize cyanobacterial community composition and determine if specific groups of cyanotoxins (anatoxins, cylindrospermopsins, microcystins, nodularins, and saxitoxins) were present. We report the identification of numerous potentially harmful taxa and the co-occurrence of multiple toxins, previously undocumented, at several locations. Our findings reveal a potential health concern based on the range of organisms present and the widespread prevalence of recognized toxic compounds. Our results raise concerns for recreation, harvesting of finfish and shellfish, and wildlife and desalination operations, highlighting the need for assessments and implementation of monitoring programs. Such programs appear to be particularly necessary in regions susceptible to urban influence. Quelle: Verlagsinformation

China's Aid Engagements in South-South Cooperation: Towards Developing a New Theory of Sino-Zimbabwe Aid Relations
Creators: name: Jaji, Henry Munashe
Publisher: name: Swinburne
Year: 2024

description: This thesis looked at China's aid relations with Zimbabwe as a reflection of how China uses aid to engage with other developing nations. The analysis culminates into the development of a theory that proposes that China uses aid as a foreign policy tool, but the success of the policy depends on the role played by the aid host countries. The study argues that host countries are not pawns in the hands of China, being used to advance China's interests, but they are active participants conscious to China interests and strategies. The study helps readers understand the context in which China relates with aid host nations.

description: Die in dieser Schrift vorgestellten Studien belegen, dass die Behandlung mittels therapeutischer Stimulationsverfahren eine sinnvolle und wirksame alternative Behandlungsoption bei Patienten mit TRD darstellt. Die EKT sollte als optima ratio bei der Akutbehandlung von Patienten mit TRD eingesetzt werden. Die Ergebnisse der magnetresonanzspektroskopischen und neuropsychologischen Untersuchung nach EKT zeigen, dass bestimmte kognitive Defizite bei der TRD therapieinduziert sind. Daher wird empfohlen, sowohl Patienten als auch Angehörige über die möglichen Einbußen des autobiographischen Gedächtnisses vor der EKT gewissenhaft aufzuklären. Aus den Erfahrungen unserer EKT und VNS-Studien ließen sich für die Patientenselektion zum Einschluss in die Studien zur THS wichtige Erkenntnisse ableiten. So sollten nur Patienten für einen Einschluss in THS-Studien aufgenommen werden, die in früheren Behandlungsschritten auf eine EKT respondiert hatten. Es besteht die Annahme einer besseren Therapieresponse. In den Experimenten zu den klinischen Effekten der tiefen Hirnstimulation wurden Nachweise für eine Beteiligung des subgenualen ACC an der Verarbeitung emotionaler Empathieprozesse vorgelegt. Zudem legen die hier erstmals am Menschen durchgeführten intrazerebralen Ableitungen im Cg25-Areal eine störungsspezifische oszillatorische Aktivität nahe. Durch den Nachweis der hier teils erstmals beschriebenen Auffälligkeiten erweitern sie das Verständnis der Rolle des fronto-limbischen Netzwerkes und des ACC für ausgewählte kognitive und affektive Funktionen. Wenngleich erste Ergebnisse noch keine zukunftsweisenden Erfolge in der Wirksamkeit erzielten, erlauben die generell reversiblen Veränderungen der Netzwerkaktivität unter THS nicht nur eine kausaltherapeutische Intervention in der Behandlung ansonsten therapierefraktärer Patienten, sondern bieten in der experimentellen Nutzung auch einen Erkenntnisgewinn über die, der Depression zugrunde liegenden, pathophysiologischen Mechanismen und deren beteiligten neuronalen Strukturen. Es ist in der Zukunft unbedingt notwendig die Verläufe der stimulierten Patienten im Hinblick auf potentielle Biomarker, aber auch besonders im Hinblick auf eine mögliche Gefährdung durch eine erhöhte Suizidalität, sowie mit der Frage nach kognitiven Nebenwirkungen aufmerksam zu verfolgen.

description: Phagocytosis and the formation of reactive oxygen species (ROS) in phagocytic leukocytes are an effective killing mechanism of the innate host defense. These cellular processes of innate immunity function in a complex interplay with humoral factors. C-reactive protein (CRP) in its activated, monomeric isoform (mCRP) has been shown to activate immune cells via the classical complement pathway. We investigated the complement-dependent effects of monomeric CRP (mCRP) on neutrophils and monocyte subtypes using complement-specific inhibitors by both flow cytometry and confocal fluorescence microscopy. We demonstrate that CRP-induced ROS generation is a conformation-specific and complement-dependent process in leukocyte subsets with classical monocytes as the primary source of ROS amongst human monocyte subsets. Elucidation of this complex interplay of CRP and complement in inflammation pathophysiology might help to improve anti-inflammatory therapeutic strategies.

description: Background: An Infectious Disease vaccine specialist joined our institution’s Cochlear Implant Team in 2010 in order to address the high percentage of non-compliance to immunization prior to surgery identified previously from an internal review. The purpose of this study was to (1) review the immunization status of cochlear implant recipients in 2010–2014, (2) assess if introducing a vaccine specialist made a significant change in vaccination compliance and (3) elucidate any barriers to vaccination compliance. Methods: Retrospective chart review and a telephone survey. Medical records of 116 cochlear implant recipients between 2010 and 2014 were reviewed. A telephone survey was conducted to obtain the current vaccination status in children who required post-operative vaccinations with incomplete records on chart review and, if applicable, the reason for non-compliance. Results: Between 2010 and 2014, 98% of children were up-to-date at the time of surgery, compared to 67% up-to-date at the time of surgery between 2002 and 2007. 27 children were included in our post-operative immunization analysis. 29.6% (8/27) failed to receive necessary vaccinations post-surgery. Pneumovax-23, a vaccine for high-risk patients (such as cochlear implant candidates) was missed in all cases. Conclusion: Pre-operative vaccination for cochlear implant recipients improved dramatically with the addition of a vaccine specialist. However, a significant proportion of patients requiring vaccinations post-surgery did not receive them. The main reason for non-compliance was due to parents being unaware that their children required this vaccine postoperatively by being “high-risk”. Although improvement was demonstrated, a communication gap continued to impede the adequacy of vaccination uptake in pediatric cochlear implant recipients following surgery at age 2 when the high-risk vaccine was due.

description: Radio astronomy observatories with high throughput back end instruments require real-time data processing. While computing hardware continues to advance rapidly, development of real-time processing pipelines remains difficult and time-consuming, which can limit scientific productivity. Motivated by this, we have developed Bifrost: an open-source software framework for rapid pipeline development.(a) Bifrost combines a high-level Python interface with highly efficient reconfigurable data transport and a library of computing blocks for CPU and GPU processing. The framework is generalizable, but initially it emphasizes the needs of high-throughput radio astronomy pipelines, such as the ability to process data buffers as if they were continuous streams, the capacity to partition processing into distinct data sequences (e.g. separate observations), and the ability to extract specific intervals from buffered data. Computing blocks in the library are designed for applications such as interferometry, pulsar dedispersion and timing, and transient search pipelines. We describe the design and implementation of the Bifrost framework and demonstrate its use as the backbone in the correlation and beamforming back end of the Long Wavelength Array (LWA) station in the Sevilleta National Wildlife Refuge, NM.

description: Increased media coverage of plastic pollution in the environment and import bans on plastic waste in several countries have resulted in plastic waste becoming one of the most discussed waste streams in recent years. In the European Union (EU), only about one-third of the post-consumer plastic waste is recycled; the rest goes to energy recovery and landfilling in equal parts. In connection to the necessary increase in efforts to achieve the ambitious EU recycling targets, chemical recycling is currently receiving more and more attention. The assumption is that chemical recycling processes could open up new waste streams for recycling and generate valuable raw materials for the chemical industry. Although there exists no legal definition for chemical recycling, there is more or less agreement that it covers the conversion of plastic polymers into their monomers or chemical building blocks. Techniques such as gasification, pyrolysis and liquefaction as well as solvolysis can be used for chemical recycling. So far, only few large-scale plants for chemical recycling exist worldwide. This article presents the different processes by means of examples from (formerly) running installations and their suitability for plastics recycling is assessed. However, to date, only few chemical recycling plants are in continuous operation, and further scientific evidence for the ecological and economic benefits is still necessary for final evaluation.

description: Currently, steelmaking ladles are monitored by experienced operators manually in which the actual stirring magnitude is difficult to estimate. Over recent years, contact-free acoustic sensor arrays have been tested under experimental conditions in some steelmaking applications. This study applied multiple microphones to monitor the gas-stirring process. The clear relationship between peak frequencies and flow rate, and detection of build-ups as well as closed eye using PSD amplitudes of sound can significantly improve the understanding of gas-stirring process monitoring. Overall outcomes of this study are expected to benefit ladle operators in understanding ladle-related issues as well as enhancing process monitoring.

description: A kind of composite was designed and additive manufacturing (AM) technology was utilized in the braiding structure fabrication. The printed polylactic acid (PLA) braiding structures were integrated with two types of resins (Epon 828 resin and urethane dimethacrylate/triethylene glycol dimethacrylate (UDMA/TEDGMA) resin) used as the matrix to make composite specimens. The compression test of the composite specimens showed that the printed PLA braiding structures had the effect of varying the compression properties of pure resins: it decreased the compression properties of Epon 828 resin, but increased those of UDMA/TEGDMA resin. Observing scanning electron microscope (SEM) images, it was noted that the decreasing and increasing in the compression properties of the specimens were related to the bonding compactness between the printed braiding structure and resins. Our results may suggest a new methods for the fast manufacturing of AM-based composites, further research directions, and potential applications of this kind of composites.

description: Background: Bioengineered plant-derived Rhamnogalacturonan-Is (RG-Is) from pectins are potential candidates for surface nanocoating of medical devices. It has recently been reported that RG-I nanocoatings may prevent bacterial infection and improve the biocompatibility of implants. The aim of the study was to evaluate in vitro impact of bioengineered RG-I nanocoatings on osteogenic capacity and proinflammatory cytokine response of murine osteoblasts following Porphyromonas gingivalis infection. Methods: Murine MC3T3-E1 osteoblasts and isolated primary calvarial osteoblasts from C57BL/6J (B6J osteoblasts) mice were infected with P. gingivalis and incubated on tissue culture polystyrene plates with or without nanocoatings of unmodified RG-Is isolated from potato pulps (PU) or dearabinanated RG-Is (PA). To investigate a behavior of infected osteoblasts cultured on RG-Is cell morphology, proliferation, metabolic activity, mineralization and osteogenic and pro-inflammatory gene expression were examined. Results: Following P. gingivalis infection, PA, but not PU, significantly promoted MC3T3-E1 and BJ6 osteoblasts proliferation, metabolic activity, and calcium deposition. Moreover, Il-1b, Il-6, TNF-α, and Rankl gene expressions were downregulated in cells cultured on PU and to a higher extent on PA as compared to the corresponding control, whereas Runx, Alpl, Col1a1, and Bglap gene expressions were upregulated vice versa. Conclusion: Our data clearly showed that pectin RG-Is nanocoating with high content of galactan (PA) reduces the osteoblastic response to P. gingivalis infection in vitro and may, therefore, reduce a risk of inflammation especially in immunocompromised patients with rheumatoid or periodontal disorders.

description: The first cervical vertebra is the atlas, which forms the connecting joint between the head and the spine. It is a highly specialized vertebra closely related to the vital centers. The craniovertebral junction is an important area where surgeons usually tread to treat pathology, injury, or joint instability. The aim of the current study is to provide comprehensive data of the first cervical vertebra along with the variation of its bony structure. Methods: 50 dry atlases were photographed. The Image J software was used to take several morphometric measurements to completely understand the anatomy of the bone. Results: The superior facet was classified into 6 varieties Oval, duplicated, 8 shaped, kidney, comma, and sinuous. The variation of the inferior facet was categorized into four different types: circular, oval quadrilateral, and triangular. The dimensions of the posterior, anterior arch and groove for the vertebral artery were noted. Variants of hypoplastic foramen transversarium and retrotransverse foramen were found in the specimens. A midline defect of the posterior arch was discovered and explained. The correlation between the area of the foramen transversarium and the vertebral canal was analyzed. Conclusion: There is a lot of variation in the anatomy of the atlas. This study provides comprehensive data on 26 different variables of a single bone. It explains different variations found during the study and correlates the parameters. This will assist the neurosurgeon as well as the orthopaedician working in this region to customize the surgery so as to avoid injury to the important neurovascular structures closely related to the first cervical vertebra and also in the treatment of joint pathologies, plan novel approaches to customize management.
A standardised and practicable approach to calculating aircraft noise according to CNOSSOS-EU

description: The introduction of the EU-wide harmonised noise assessment methods CNOSSOS-EU according to Annex II of the Environmental Noise Directive 2002/49/EG aims at establishing a calculation methodology for determining, inter alia, aircraft noise (CNOSSOS-Air), which will be applicable as from 31.12.2018 in all member states. Before the implementation of CNOSSOS-EU the national assessment methods differed in algorithms describing the sound source and propagation and furthermore in regard to input data from national databases. Additional deviations arose from different software implementations and parameter settings made by the end user. This led to the development of CNOSSOS-EU with the aim of enhanced comparability of noise maps. In the case of aircraft noise the decision was made in favor of the third edition of Doc. 29 of the European Civil Aviation Conference (ECAC). This calculation method is a highly flexible instrument enabling flight procedure modelling in any precision depending on the application purpose. An essential precondition for comparable computation results are unique specifications for individual calculation steps allowing for a uniform approach to noise mapping. Here in particular, CNOSSOS-Air still has potential for optimisation. Due to the multitude of loopholes, e.g. when modelling turns or lateral track dispersions of swathes, the calculation method is in many ways unspecified leaving the end user with a scope of interpretation. This leads to different modelling approaches which substantially complicate a quality assurance. Furthermore CNOSSOS-Air generates flight profiles using procedural steps thus requiring sound knowledge of flight procedures, particularly the setting of thrust, flaps and landing gear. Since these parameters are usually insufficiently known they must be estimated which leads to results that correspond more or less to reality. Based on the national implementation of CNOSSOS In Germany it is the intention to show how CNOSSOS-Air can be concretised to assure both quality and practicality.

description: The aim of this Hypothesis and Theory is to question the recently increasing use of the “race” concept in contemporary genetic, psychiatric, neuroscience as well as social studies. We discuss “race” and related terms used to assign individuals to distinct groups and caution that also concepts such as “ethnicity” or “culture” unduly neglect diversity. We suggest that one factor contributing to the dangerous nature of the “race” concept is that it is based on a mixture of traditional stereotypes about “physiognomy”, which are deeply imbued by colonial traditions. Furthermore, the social impact of “race classifications” will be critically reflected. We then examine current ways to apply the term “culture” and caution that while originally derived from a fundamentally different background, “culture” is all too often used as a proxy for “race”, particularly when referring to the population of a certain national state or wider region. When used in such contexts, suggesting that all inhabitants of a geographical or political unit belong to a certain “culture” tends to ignore diversity and to suggest a homogeneity, which consciously or unconsciously appears to extend into the realm of biological similarities and differences. Finally, we discuss alternative approaches and their respective relevance to biological and cultural studies.

description: Background The cells of the mesencephalic trigeminal nucleus (MTN) are the proprioceptive sensory neurons that innervate the jaw closing muscles. These cells differentiate close to the two key signalling centres that influence the dorsal midbrain, the isthmus, which mediates its effects via FGF and WNT signalling and the roof plate, which is a major source of BMP signalling as well as WNT signalling. Methods In this study, we have set out to analyse the importance of FGF, WNT and BMP signalling for the development of the MTN. We have employed pharmacological inhibitors of these pathways in explant cultures as well as utilising the electroporation of inhibitory constructs in vivo in the chick embryo. Results We find that interfering with either FGF or WNT signalling has pronounced effects on MTN development whilst abrogation of BMP signalling has no effect. We show that treatment of explants with either FGF or WNT antagonists results in the generation of fewer MTN neurons and affects MTN axon extension and that inhibition of both these pathways has an additive effect. To complement these studies, we have used in vivo electroporation to inhibit BMP, FGF and WNT signalling within dorsal midbrain cells prior to, and during, their differentiation as MTN neurons. Again, we find that inhibition of BMP signalling has no effect on the development of MTN neurons. We additionally find that cells electroporated with inhibitory constructs for either FGF or WNT signalling can differentiate as MTN neurons suggesting that these pathways are not required cell intrinsically for the emergence of these neurons. Indeed, we also show that explants of dorsal mesencephalon lacking both the isthmus and roof plate can generate MTN neurons. However, we did find that inhibiting FGF or WNT signalling had consequences for MTN differentiation. Conclusions Our results suggest that the emergence of MTN neurons is an intrinsic property of the dorsal mesencephalon of gnathostomes, and that this population undergoes expansion, and maturation, along with the rest of the dorsal midbrain under the influence of FGF and WNT signalling.
The role of translation in the building of national identities: The case of colonial Mexico (1521--1821)

description: The purpose of this doctoral research is to demonstrate that translation, as a form of representation, is present in the elaboration of a discourse on the nation in colonial Mexico, or New Spain. To this end, a catalogue of 712 translational products is explored by means of a classification based on a conceptual framework provided by nationalism studies. This approach leads to see how, individually and collectively, one group of translations weave the canvass of an "imagined community" of faithful, on which three other groups intertwine narratives of foundational myths, instill a sense of belonging to a continuum of classical civilizations, and, lastly, incorporate New Spain to the concert of modern nations. Historiography is part of this evolution, and the presence of translation and subsequent rewritings are traced in the fixing of a national history.
