description: Socio-economic importance of welland plant speciesin NW of Morocco. The exploitation of the welland plants in NW of Morocco presents a particular importance. The most often, it belongs the traditional economic sector. Nevertheless, no study of evaluation has been devoted to this subject. An inquiry led in provinces of NW of Morocco has allowed us to inventory 33 wetland plant species exploited as weil as their different utilizations. Potential exploitationshave been alsa underlined. Sa as to evaluate the fallen economic of the macrophytes, we estimate the uni t price Of the biomàss and the main products finish, the financial product and/or the potential netincome by exploiting for 15 of they. Real substitutes namely natura! species (imported or upland ones) , artificiaI substitutes and some local activities were used in the relative economic evaluation of macrophytes. The main social impacts of these types of exploitation were underlined.

description: Bei der Produktion von Trockenfutter für Hunde und Katzen werden erhebliche Mengen an Fleischmehlen als Quelle von Proteinen eingesetzt. Das innovative Produktionsverfahren ersetzt Fleischmehl durch Frischfleisch und Innereien. Dadurch entfällt der Prozess der Fleischmehlproduktion und der damit verbundene Energieaufwand weitgehend. Durch das innovative Verfahren lies sich der Energiebedarf prozessübergreifend um 29,59 % senken. Zudem reduziert sich der Frischwassereinsatz um 3.000 m3/a und auf den Einsatz von 8.400 t/a Fleischmehl kann verzichtet werden. Das innovative Verfahren führt allerdings zu deutlich höherem Aufwand in der Produktion. Das betrifft sowohl die Anforderungen an die Produktionsplanung, der Produktionssteuerung als auch dem Bedarf an Arbeitskräften in der Produktion. Quelle: Forschungsbericht
description: Meat meals are a major source of protein in feed for dogs and cats. The innovative production procedure substitutes meat meal by fresh meat and offals. Therefore the process of meat meal production is not necessary anymore. This leads to an overall reduction in energy consumption of 29,59 %. Furthermore the innovative production procedure reduces the use of 3,000 m3/a of water and 8,400 t/a of meat meal. The innovative procedure requires a more complex planning of production and logistics, as well as more labour in the production. Quelle: Forschungsbericht

description: Circular data can be found across many areas of science, for instance meteorology (e.g., wind directions), ecology (e.g., animal movement directions), or medicine (e.g., seasonality in disease onset). The special nature of these data means that conventional methods for non-periodic data are no longer valid. In this paper, we consider wrapped Gaussian processes and introduce a spatial model for circular data that allow for non-stationarity in the mean and the covariance structure of Gaussian random fields. We use the empirical equivalence between Gaussian random fields and Gaussian Markov random fields which allows us to considerably reduce computational complexity by exploiting the sparseness of the precision matrix of the associated Gaussian Markov random field. Furthermore, we develop tunable priors, inspired by the penalized complexity prior framework, that shrink the model toward a less flexible base model with stationary mean and covariance function. Posterior estimation is done via Markov chain Monte Carlo simulation. The performance of the model is evaluated in a simulation study. Finally, the model is applied to analyzing wind directions in Germany.

description: As the first stage of a larger project, this paper presents experiences of two e-Entrepreneurs in the light of Open Source Software (OSS) being accepted globally. Unlike proprietary software (such as Windows), OSS comes with its internal details visible to its users. The significant implications of this unique style of software distribution for e-Entrepreneurs are examined. Recommendations arising from the interviews include the need to be technically competent; understanding the reasons behind adopting this strategy; and identifying and addressing customers' requirements. Authors also found similarities between traits (such as being visionary; being responsive to market changes) which make an entrepreneur and e-Entrepreneurs successful.

description: This dissertation explored the way in which bumblebees' visual system helps them discover their first flower. Previous studies found bees have unlearned preferences for parts of a flower, such as its colour and shape. The first study pitted two variables against each other: pattern type: sunburst or bull's eye, versus the location of the pattern: shapes appeared peripherally or centrally. We observed free-flying bees in a flight cage using Radio-Frequency Identification (RFID) tracking. The results show two distinct behavioural preferences: Pattern type predicts landing: bees prefer radial over concentric patterns, regardless of whether the radial pattern is on the perimeter or near the centre of the flower. Pattern location predicts exploration: bees were more likely to explore the inside of artificial flowers if the shapes were displayed near the centre of the flower, regardless of whether the pattern was radial or concentric. As part of the second component, we implemented a mathematical model aimed at explaining how bees come to prefer radial patterns, leafy backgrounds and symmetry. The model was based on unsupervised neural networks used to describe cognitive mechanisms. The results captured with the results of multiple behavioural experiments. The model suggests that bees choose computationally "cheaper" stimuli, those that contain less information. The third study tested the computational load hypothesis generated by the artificial neural networks. Visual properties of symmetry, and spatial frequency were tested. Studying free-flying bees in a flight cage using motion-sensitive video recordings, we found that bees preferred 4-axis symmetrical patterns in both low and high frequency displays.
The Sundarbans, the World's Largest Tidal Halophytic Mangrove Forest: Its Economic and Ecological Significance

Year: 2024

description: Abstract

 

The Sundarbans, located along the southwestern coast of Bangladesh and southeastern India, is a remarkable ecosystem characterized by extensive mangrove forests, marshlands, and waterways, spreading across approximately 10,000 square kilometers. This vast area is recognized as the world's largest tidal halophytic mangrove forest, known for its ability to thrive in warm, humid climates and its unique assortment of salt-resistant plant life. The Sundarbans mangroves are essential for the livelihoods of coastal communities, supporting fishing industries and offering resources like timber, fuel woods, honey, and medicinal plants. Moreover, the mangroves play a crucial role in coastal protection, shielding against cyclones, storm surges, tidal waves, and erosion. Additionally, the mangroves serve essential ecological functions, including carbon sequestration, and providing habitats for various plant and animal species. Despite the pivotal functions, the mangroves face significant threats from human activities, notably pollution, land use changes, and the impacts of climate change. The escalating demand for resources has led to extensive deforestation resulting in habitat degradation and a reduction in the Sundarbans' size. This review delves into the economic and ecological features of the Sundarbans, examining its landscapes, biodiversity, and the obstacles posed by resource exploitation, and climate change, while also considering potential strategies for mitigation.

Radio Frequency IDentification Technology

description: Localization and motion control (navigation) are two major tasks for a successful mobile robot navigation. The motion controller determines the appropriate action for the robot’s actuator based on its current state in an operating environment. A robot recognizes its environment through some sensors and executes physical actions through actuation mechanisms. However, sensory information is noisy and hence actions generated based on this information may be non-deterministic. Therefore, a mobile robot provides actions to its actuators with a certain degree of uncertainty. Moreover, when no prior knowledge of the environment is available, the problem becomes even more difficult, as the robot has to build a map of its surroundings as it moves to determine the position. Skilled navigation of a differential drive mobile robot (DDMR) requires solving these tasks in conjunction, since they are inter-dependent. Having resolved these tasks, mobile robots can be employed in many contexts in indoor and outdoor environments such as delivering payloads in a dynamic environment, building safety, security, building measurement, research, and driving on highways. This dissertation exploits the use of the emerging Radio Frequency IDentification (RFID) technology for the design and implementation of cost-effective and modular control techniques for navigating a mobile robot in an indoor environment. A successful realization of this process has been addressed with three separate navigation modules. The first module is devoted to the development of an indoor navigation system with a customized RFID reader. This navigation system is mainly pioneered by mounting a multiple antenna RFID reader on the robot and placing the RFID tags in three dimensional workspace, where the tags’ orthogonal position on the ground define the desired positions that the robot is supposed to reach. The robot generates control actions based on the information provided by the RFID reader for it to navigate those pre-defined points. On the contrary, the second and third navigation modules employ custom-made RFID tags (instead of the RFID reader) which are attached at different locations in the navigation environment (on the ceiling of an indoor office, or on posts, for instance). The robot’s controller generates appropriate control actions for it’s actuators based on the information provided by the RFID tags in order to reach target positions or to track pre-defined trajectory in the environment. All three navigation modules were shown to have the ability to guide a mobile robot in a highly reverberant environment with variant degrees of accuracy.

description: Interactive dissection simulation is an important research topic in the virtual reality (VR) community. There are many efforts on this topic; however, most of them focus on building a realistic simulation system regardless of the cost, and they often require expensive workstations and specialized haptic devices which prevent broader adoption. We show how to build a realistic dissection simulation at an affordable cost, which opens up applications in elementary education for virtual dissections which are currently not feasible. In this thesis, we present a fast and robust haptic system for interactive dissection simulations of finite elements based deformable objects which supports two type of haptic interactions: point contacts and cuts. We design a semi-progressive virtual dissection scheme of deformable objects in a real-time application. The quality and performance of visual/haptic feedback is demonstrated on a low-end commercial desktop PC with a haptic device.

description: The COVID-19 pandemic has spread worldwide, affecting millions of people and exposing them to home quarantine, isolation, and social distancing. While recent reports showed increased distress and depressive/anxiety state related to COVID-19 crisis, we investigated how home quarantine affected sleep parameters in healthy individuals. 160 healthy individuals who were in home quarantine in April 2020 for at least one month participated in this study. Participants rated and compared their quantitative sleep parameters (time to go to bed, sleep duration, getting-up time) and sleep quality factors, pre-and during home quarantine due to the COVID-19 pandemic. Furthermore, participants’ chronotype was determined to see if sleep parameters are differentially affected in different chronotypes. Time to fall asleep and get-up in the morning were significantly delayed in all participants, indicating a significant circadian misalignment. Sleep quality was reported to be significantly poorer in all participants and chronotypes. Poor sleep quality included more daily disturbances (more sleep disturbances, higher daily dysfunctions due to low quality of sleep) and less perceived sleep quality (lower subjective sleep quality, longer time taken to fall asleep at night, more use of sleep medication for improving sleep quality) during home quarantine. Home quarantine due to COVID-19 pandemic has a detrimental impact on sleep quality. Online interventions including self-help sleep programs, stress management, relaxation practices, stimulus control, sleep hygiene, and mindfulness training are available interventions in the current situation.

description: Depuis 2010, le gouvernement canadien a créé une loi qui exige 5% de biocarburant dans l’essence, et ce, dans un contexte d’insécurité alimentaire dont souffrent les plus défavorisés. Cette thèse fait l’analyse critique du discours des organisations privées qui ont promu les biocarburants dans ce contexte. Comment en sont-ils arrivés à fabriquer la normalité de l’usage des biocarburants? Cette dernière se produit par la mise en valeur de nouveaux emplois dans l’industrie, la promotion d’une économie rurale vigoureuse, la présentation de l’État comme facilitateur des marchés ainsi que l’accent mis sur les impacts environnementaux favorables des biocarburants. La normalisation s’explique aussi par la dénaturation des grains et la radicalisation du rôle du fermier afin que ceux-ci concordent avec l’idéologie (néo)libérale. Il importe que la criminologie critique, se positionne au sein d’une zémiologie, dont les objets d’études portent sur les torts sociaux émanant des structures et l’organisation inégalitaire de nos sociétés.

description: The compositional technique of cross partitioning is one of Luigi Dallapiccola's most used twelve-tone devices. Through a detailed analysis of three contrapuntal canonic movements from Dallapiccola's Quaderno Musicale di Annalibera, I examine his use of cross partitioning as a motivic tool and as a referential collection. The development of the BACH motive and the derivation of tone-row statements reflects on Dallapiccola's extensive use of cross partitioning and his compositional principles used to achieve a sense of polarity. Upon a preliminary analysis based on set-theory analysis set out by Joseph Straus I draw an interpretive analysis through Alegant's cross partitioning model as well as develop my own set of parameters for interpretation in regards to polarity which is based on intervallic stability.
How should father support be in breastfeeding?: A systematic review
Creators: name: Simal Yavuz, Nurgul

description: Aim: Breastfeeding is the newborn's best chance for a good start in life. Breastfeeding is seen primarily as the mother's duty. However, the participation and support of the father as well as the mother in breastfeeding will help breastfeeding to be more effective and long-lasting.The purpose of this systematic review is to seek answers to the question “How should father support be in breastfeeding?”

Materials and Methods: The study was carried out based on a literature review on Web of Science, Pubmed, Scholar Google, EBSCO Host, and Science Direct databases. The keywords used in the search were "father support," "paternal support," "father's role," and "breastfeeding". The search strategy was prepared by using MESH (Medical Subject Headings) terms. All qualitative studies on the subject were discussed.

Results: A total of 177 studies were examined. 11 studies were included in the review. The main themes obtained; emotional support, giving support in practical matters, having knowledge about breastfeeding and breast milk, developing a positive attitude towards breastfeeding, and active involvement in the decision-making process.

Conclusion: Fathers' knowledge about and attitudes towards breastfeeding, involvement in the decision-making process, and their practical and emotional support about breastfeeding were highly important in terms of the initiation and continuation of breastfeeding and the mother’s coping with the problems in the breastfeeding process. When fathers receive counseling services together with mothers and take part in education programs, this will enable them to have a positive attitude towards breastfeeding and to be effective on mothers' decisions.

description: Alternate reality games (ARG) are a relatively new type of game that distributes game content across several media without explicitly identifying that content as part of a game. While players benefit from this aesthetically immersive experience the type of game has the potential to cause confusion over the status of its dispersed content as real or as part of a game. This thesis offers a case study of the 2012 game. The case is contextualized within the disciplines of media studies and games studies, in a wider digital culture where the ubiquity of technology converges to user experience design. A theoretical framework based on Charles S. Peirce’s semiotic, supplemented by Erving Goffman’s frame analysis and James J. Liszka’s transvaluation theory is used to explain the ARG’s problematic relation to the experience of reality.

description: There is a growing interest in assessing the neurotoxic potential and endocrine disrupting properties of perfluoroalkyl compounds (PFCs). Several studies have reported in vitro and in vivo effects related to neuronal development, neural cell differentiation, pre- and post- natal development and behaviour. PFC exposure altered hormone levels (e.g. thyroid hormone, estrogen, and testosterone) and the expression of hormone-responsive genes in mammalian and aquatic species. Hormone-mediated events are critical in central nervous system development and function, especially those controlled by thyroid hormones (THs). The studies presented in this thesis are the first to assess the effects of PFCs on primary cultures of neuronal cells in two avian species; the domestic chicken (Gallus domesticus) and herring gull (Larus argentatus). The following TH-responsive genes were examined using real-time RT-PCR: type II iodothyronine 5’-deiodinase (D2), D3, transthyretin (TTR), neurogranin (RC3), octamer motif binding factor (Oct-1), and myelin basic protein (MBP). Several PFCs were shown to alter mRNA expression levels of genes associated with the TH pathway in avian neuronal cells. It was determined that short-chained PFCs (<8 carbons) altered the expression of TH-responsive genes to a greater extent than long-chained PFCs (≥8 carbons). Although several significant changes in mRNA expression were observed in TH-responsive genes following PFC exposure in chicken embryonic neuronal (CEN) cells (Chapter 2), there were fewer changes in herring gull embryonic neuronal (HGEN) cells (Chapter 3). The mRNA levels of D2, D3, TTR, and RC3 were altered following treatment with several short-chained PFCs in CEN cells. Oct-1 and RC3 expression were induced following treatment with several short-chained PFCs in HGEN cells. These studies are the first to report that PFC exposure alters mRNA expression in primary cultures of avian neuronal cells and provide insight into the possible mechanisms of action of PFCs in the avian brain.

description: Parkinson’s disease (PD) is a common neurodegenerative disorder that is characterized by the degeneration of dopaminergic (DA) neurons in the substantia nigra and motor deficits. Although the majority of PD cases are sporadic, several genetic defects in rare familial cases have been identified. Animal models of these genetic defects have been created and have provided unique insights into the molecular mechanisms of the pathogenesis of PD. However, the etiology of PD is still not well understood. Here, taking advantage of the unique features offered by zebrafish, I characterized the functions of PINK1 (PTEN-induced kinase 1) gene, which is associated with recessive familial PD, in the development and survival of DA neurons. In zebrafish, antisense morpholino knockdown of pink1 did not cause a large loss of DA neurons in the ventral diencephalon (vDC), but the patterning of these neurons and their projections were perturbed. The pink1 morphants also showed impaired response to touch stimuli and reduced swimming behaviour. Moreover, the pink1 knockdown caused a significant reduction in the number of mitochondria, as well as mitochondrial morphological defects such as smaller size or loss of cristae, thus affecting mitochondrial function. These results suggest that zebrafish pink1 plays conserved important roles in the development of DA neurons and in the mitochondrial morphology and function. To better follow DA neurons after injury or administration of toxins, I generated a transgenic zebrafish line, Tg(dat:EGFP), in which the green fluorescent protein (GFP) is expressed under the control of cis-regulatory elements of dopamine transporter (dat). In Tg(dat:EGFP) fish, all major groups of DA neurons are correctly labeled with GFP, especially the ones in the vDC, which are analogous to the ascending midbrain DA neurons in mammals. In addition, we observed that the DA neurons in the vDC could partially be replaced after severe laser cell ablation. This suggests that zebrafish may have the unique capacity of regenerating DA neurons after injury. Taken together, my studies suggested that zebrafish could be a useful alternative animal model for the study of the molecular mechanisms underlying PD and for the screening of potential therapeutic compounds for PD.

description: The development of digital technologies, particularly multimedia, has been a site of intense activity for museums over the past decade or so. While the impact of multimedia on museums and museum interpretation has been widely debated, their use in museum education programmes — those designed against specified curriculum outcomes — has received less critical attention. Multimedia have radically altered relationships between education authorities and museums, teachers and learners, the physical museum and the virtual. The Australian National Inquiry into School History, which reported in 2000, called for the increased use of the resources of museums and other cultural heritage institutions in the teaching of school history, particularly through online programmes. While this call requires renewed consideration of the distinctiveness of the museum learning environment, the Inquiry’s conceptualisation of historical literacy and the pedagogical uses of new communication technologies can assist the work of museums in their response to these contested domains.

Cette thèse s'intéresse au cas de l'Argentine, pays qui a vécu les deux extrêmes de ce continuum, en tentant de déterminer si cette nation sud-américaine a connu un réinvestissement dans la cause des droits humains comparable à celui vécu par la littérature spécialisée à partir des années 1990. À cet effet, nous concentrerons notre attention sur la périodisation proposée par Thomas Wright dans son ouvrage "State Terrorism in Latin America: Chile, Argentina, and International Human Rights" en essayant de déterminer sa vraisemblance.

Observational Study

description: This multi-method study provides detailed information about the friendships of 87 children with ADHD (77.0% boys) and 46 comparison children (73.9% boys) between the ages of 7 and 13. The methods used in the study included parent and teacher ratings, self-report measures, and direct observation of friends’ dyadic behaviours in three structured analogue tasks. Results indicated that, in contrast with comparison children, children with ADHD had friends with high levels of ADHD and oppositional symptoms; they perceived fewer positive features and more negative features, and were less satisfied in their friendships. Observational data indicated that children with ADHD performed both more legal and more illegal manoeuvres than comparison children in a fast-paced competitive game. While negotiating with their friends, children with ADHD made more insensitive and self-centred proposals than comparison children. In dyads consisting of one child with ADHD and one typically developing child, children with ADHD were often more controlling than their non-diagnosed friends. Globally, these results were robust and did not seem to be affected by age differences, ADHD subtypes, comorbidities, and medication status. Given the increased recognition of ADHD in adolescence and adulthood as well as the fact that negative peer reputation in childhood very strongly predicts mental-health status by early adulthood, this research may lead to the discovery of meaningful ways to help people with ADHD achieve improved mental health and happiness over their lifespan.

The Economics of Climate Change

description: This doctoral thesis contains three essays on the economics of climate change and the electricity sector. The first essay deals with the subject of greenhouse gas (GHG) emissions and economic growth. The second essay addresses the issues of climate change policies, especially the role of the emergent innovative technologies, and the restructuring of the electricity sector. The third essay presents a model of transmission investments in electric power networks. Chapter One studies the impacts of climate change on economic growth in the world economies. The paper contains explicit formalization of the depletion process of exhaustible fossil fuels and the phase of technology substitution. The impacts of climate change on capital flows and welfare across countries are also investigated. The restructuring of the electricity sector is studied in Chapter Two. It also analyzes how climate change policies can benefit from emergent innovative technologies and how emergent innovative technologies can lower GHG emissions. It is shown that the price of electricity is strictly rising before emergent innovative firms with zero GHG emissions enter the market, but strictly declining as the entry begins. In Chapter Three, a model of electricity transmission investments from the perspective of the regulatory approach is formulated. The Mid-West region of Western Australia, a sub-system of the South West Interconnected System is considered. In contrast with most models in the literature that deal only with network deepening, this model deals with both network deepening and network widening. Moreover, unlike the conventional investment models which are static and deal only with the long run, this model is dynamic and focuses on the timing of the infrastructure investments. The paper is a study of an optimal transmission investment program which is part of the optimal investment program for an integrated model in which investments in transmission and investments in generation are made at the same time.
Le roman et la connaissance morale : éthique et littérature chez Jacques Bouveresse, Vincent Descombes et Sandra Laugier

description: Nous nous intéressons dans ce travail aux tentatives de Bouveresse, Descombes et Laugier de montrer que l’éthique et la connaissance morale peuvent être exprimées de façon peut-être plus juste par la littérature que par la philosophie. S’inspirant d’une conception wittgensteinienne de l’éthique comme indicible, les trois auteurs étudiés tentent de penser une relation entre éthique et littérature qui ne réduise ni la philosophie à la littérature, ni la littérature à la philosophie. Il s’agit ainsi pour nous d’évaluer les résultats de leurs travaux en voyant s’ils réussissent véritablement à penser un nouveau type de relation de la philosophie à l’un de ses autres, la littérature et donc l’art, qui dépasse les relations traditionnelles de réduction ou d’exclusion et qui tienne plus de la coopération ou de la complémentarité entre les types de discours. Ce faisant, nous nous intéressons aussi à l’impact de la philosophie analytique, et plus particulièrement de la pensée de Wittgenstein, dans le monde philosophique français, et à la signification du choix d’une pratique plus analytique de la philosophie chez les trois auteurs choisis.

description: The increasing use of chemicals in the European Union (EU) has resulted in environmental emissions and wildlifeexposures. For approving a chemical within the EU, producers need to conduct an environmental risk assessment,which typically relies on data generated under laboratory conditions without considering the ecological andlandscape context. To address this gap and add information on emerging contaminants and chemical mixtures,we analysed 30 livers of white-tailed sea eagles (Haliaeetus albicilla) from northern Germany with highresolution-mass spectrometry coupled to liquid and gas chromatography for the identification of >2400 con-taminants. We then modelled the influence of trophic position (Î´15N), habitat (Î´13C) and landscape on chemicalresidues and screened for persistent, bioaccumulative and toxic (PBT) properties using an in silico model tounravel mismatches between predicted PBT properties and observed exposures. Despite having generally lowPBT scores, most detected contaminants were medicinal products with oxfendazole and salicylamide being mostfrequent. Chemicals of the Stockholm Convention such as 4,4â€2-DDE and PCBs were present in all samples belowtoxicity thresholds. Among PFAS, especially PFOS showed elevated concentrations compared to other studies. Incontrast, PFCA levels were low and increased with Î´15N, which indicated an increase with preying on piscivorousspecies. Among plant protection products, spiroxamine and simazine were frequently detected with increasingconcentrations in agricultural landscapes. The in silico model has proven to be reliable for predicting PBTproperties for most chemicals. However, chemical exposures in apex predators are complex and do not solely relyon intrinsic chemical properties but also on other factors such as ecology and landscape. We therefore recom-mend that ecological contexts, mixture toxicities, and chemical monitoring data should be more frequentlyconsidered in regulatory risk assessments, e.g. in a weight of evidence approach, to trigger risk managementmeasures before adverse effects in individuals or populations start to manifest. © 2021 The Authors

description: Skeletal muscle is one of the largest tissues in humans and provides many pivotal functions to support life. Abnormality in skeletal muscle functions can lead to disease. For example, insulin resistance in skeletal muscle leads to type II diabetes. The underlying mechanisms that control energy balance in skeletal muscle remain largely elusive, especially at the genetic level. Here in the second chapter, I showed that MyoD mediated the transcriptional regulation of ACSL5, a mitochondrial protein, in C2C12 myoblasts via two E-box elements. A SNP rs2419621 (T) created a de novo E-box that together with the two pre-existing proximal E-boxes strongly enhances ACSL5 expression in both CV1 and C2C12 cells. In the third chapter, I identified a novel VGLL4-interacting protein IRF2BP2 and verified the interaction with co-immunoprecipitation and mammalian two-hybrid assays. Functionally, overexpression of IRF2BP2 and transcription factor TEAD1 activates mouse VEGF-A promoter in CV1 cells and enhances the biosynthesis of VEGF-A in C2C12 myoblasts. In vivo studies showed that ischemia induced the expression of IRF2BP2 by more than three fold, suggesting that IRF2BP2 could play a pivotal role during tissue ischemia. IRF2BP2 is a nuclear protein in both mouse cardiac myocytes and C2C12 myoblasts as demonstrated by immunohistochemistry and immunocytochemistry, respectively. Therefore, I sought to delineate the mechanism for the nuclear shuttling of IRF2BP2 in the fourth chapter. With various DNA alternations, I mapped the NLS to an evolutionarily conserved sequence 354ARKRKPSP361 in IRF2BP2. Deletion of the positively charged amino acids resulted in the abolishment of the NLS signal. Next, I showed that phosphorylation of serine 360 (S360) mediates the nuclear import of the protein. Whereas an alanine substitution (S360A) at the site resulted in perinuclear accumulation of the protein, an aspartic acid substitution (S360D) forced the nuclear accumulation. Nevertheless, the forced accumulation of the S360D mutant did not enhance the activation of VEGF-A promoter in CV1 cells as did the wild-type protein. My studies revealed two novel mechanisms by which skeletal muscle could harvest energy, thus providing new insight into the energy metabolism in skeletal muscle
