description: Background and Objectives Vitamin D deficiency is frequent during the winter and occurs throughout the year in the elderly or patients suffering from autoimmune diseases. The objective of this study was to evaluate the pharmacokinetic properties of oral supplementation versus a single intramuscular injection of cholecalciferol in healthy individuals. Research design and methods Up to 8,000 I.U. oral cholecalciferol was administered daily for 84 days in a 4 week dose-escalation setting to vitamin D deficient individuals. In another cohort, a single intramuscular injection of 100,000 I.U. cholecalciferol was given. In both cohorts, individuals without vitamin D intake served as the comparison group. 25-hydroxyvitamin D (25(OH)D) concentrations were measured in all individuals at defined time points throughout the studies. Results The mean 25(OH)D serum concentration increased significantly after oral cholecalciferol intake compared to the control group (day 28: 83.4 nmol/l and 42.5 nmol/l; day 56: 127.4 nmol/l and 37.3 nmol/l; day 84: 159.7 nmol/l and 30.0 nmol/l). In individuals receiving 100,000 I.U. cholecalciferol intramuscular, the mean 25(OH)D serum concentration peaked after 4 weeks measuring 70.9 nmol/l compared to 32.7 nmol/l in the placebo group (p = 0.002). The increase of 25(OH)D serum concentrations after 28 days was comparable between both routes of administration (p = 0.264). Conclusions Oral and intramuscular cholecalciferol supplementation effectively increased serum 25(OH)D concentrations.

description: Human biomonitoring (HBM) is an effective tool to assess human exposure to environmental pollutants, but comparable HBM data in Europe are lacking. In order to expedite harmonization of HBM studies on a European scale, the twin projects COPHES (Consortium to Perform Human Biomonitoring on a European Scale) and DEMOCOPHES (Demonstration of a study to Coordinate and Perform Human Biomonitoring on a European Scale) were formed, comprising 35 partners from 27 European countries. In COPHES a research scheme and guidelines were developed to exemplarily measure in a pilot study mercury in hair, cadmium, cotinine and several phthalate metabolites in urine of 6Ń11 year old children and their mothers in an urban and a rural region. Seventeen European countries simultaneously conducted this cross-sectional DEMOCOPHES feasibility study. The German study population was taken in the city of Bochum and in the Higher Sauerland District, comprising 120 mother-child pairs. In the present paper features of the study implementation are presented. German exposure concentrations of the pollutants are reported and compared with European average concentrations from DEMOCOPHES and with those measured in the representative German Environmental Survey (GerES IV). German DEMOCOPHES concentrations for mercury and cotinine were lower than the European average. However, 47% of the children were still exposed to environmental tobacco smoke (ETS) outside their home, which gives further potential for enhancing protection of children from ETS. Compared with samples from the other European countries German participating children had lower concentrations of the phthalate metabolites MEP and of the sum of 3 DEHP-metabolites (MEHP, 5OH-MEHP and 5oxo-MEHP), about the same concentrations of the phthalate metabolites MBzP and MiBP and higher concentrations of the phthalate metabolite MnBP. 2.5% of the German children had concentrations of the sum of 4 DEHP-metabolites and 4.2% had concentrations of MnBP that exceeded health based guidance values, indicating reasons for concern. Continuous HBM is necessary to track changes of pollutant exposure over time. Therefore Germany will continue to cooperate on the harmonisation of European human biomonitoring to support the chemicals regulation with the best possible exposure data to protect Europe's people against environmental health risks.

description: Aquatic plants fulfil a wide range of ecological roles, and make a substantial contribution to the structure, function and service provision of aquatic ecosystems. Given their well-documented importance in aquatic ecosystems, research into aquatic plants continues to blossom. The 14th International Symposium on Aquatic Plants, held in Edinburgh in September 2015, brought together 120 delegates from 28 countries and six continents. This special issue of Hydrobiologia includes a select number of papers on aspects of aquatic plants, covering a wide range of species, systems and issues. In this paper, we present an overview of current trends and future directions in aquatic plant research in the early twenty first century. Our understanding of aquatic plant biology, the range of scientific issues being addressed and the range of techniques available to researchers have all arguably never been greater; however, substantial challenges exist to the conservation and management of both aquatic plants and the ecosystems in which they are found. The range of countries and continents represented by conference delegates and authors of papers in the special issue illustrates the global relevance of aquatic plant research in the early twenty first century but also the many challenges that this burgeoning scientific discipline must address. © Springer International Publishing Switzerland 2017

description: Parlant l'oeuvre en termes de discours social, mais le discours social en termes de roman (Duchet), le titre devient un puissant revelateur des rapports essentiellement equivoques qu'entretient le fait litteraire au sein de la societe. C'est donc dans cet esprit que la presente these aborde les titres du roman quebecois du XXe siecle en tentant de degager les codes qui inscrivent le titre dans la socialite et dans une littearite en redefinition constante. Empruntant aux deux perspectives critiques qui ont jusqu'ici marque l'etude du titre: sociocritique (Duchet, Grivel) et semiotique (Hoek, Genette), on est amene a constater qu'au cours du siecle le titre de roman est devenu le lieu d'une polyphonie de plus en plus accusee, de moins en moins reductible a son role d'etiquette fidele au roman.

description: Background Visceral leishmaniasis (VL), caused by the members of the Leishmania donovani complex, has been responsible for devastating VL epidemics in the Sudan. Multilocus microsatellite and sequence typing studies can provide valuable insights into the molecular epidemiology of leishmaniasis, when applied at local scales. Here we present population genetic data for a large panel of strains and clones collected in endemic Sudan between 1993 and 2001. Methods Genetic diversity was evaluated at fourteen microsatellite markers and eleven nuclear sequence loci across 124 strains and clones. Results Microsatellite data defined six genetic subpopulations with which the nuclear sequence data were broadly congruent. Pairwise estimates of FST (microsatellite) and KST (sequence) indicated small but significant shifts among the allelic repertoires of circulating strains year on year. Furthermore, we noted the co-occurrence of human and canine L. donovani strains in three of the six clusters defined. Finally, we identified widespread deficit in heterozygosity in all four years tested but strong deviation from inter-locus linkage equilibrium in two years. Conclusions Significant genetic diversity is present among L. donovani in Sudan, and minor population structuring between years is characteristic of entrenched, endemic disease transmission. Seasonality in vector abundance and transmission may, to an extent, explain the shallow temporal clines in allelic frequency that we observed. Genetically similar canine and human strains highlight the role of dogs as important local reservoirs of visceral leishmaniasis.
Creative, Technical, Entrepreneurial: Formative Tensions in Game Development Higher Education

description: Higher education (HE) has become a common pathway into game development careers. Previous research with students and educators has shown how game development HE exemplifies a “creative industries” approach that seemingly marries technical and creative skills, professionalism and passion, and individualistic entrepreneurism and interdisciplinary collaboration. However, little research has considered the varied institutional contexts such students and educators find themselves entrenched in. In this article, we argue that game development HE does not simply marry the technical and creative but is instead torn between different disciplinary cultures, ideologies, and aims. Drawing from data on 119 game development HE programs in Australia, we show that while game development HE is consistently positioned as a pathway toward student employability, just what skills and identities are emphasized as crucial for such employability varies pending on the program's institutional context—ultimately showing that combining creativity and technology is neither a straightforward nor neutral process.

description: Background In the recent years, a role of the immune system in Huntington’s disease (HD) is increasingly recognized. Here we investigate the presence of T cell activating auto-antibodies against angiotensin II type 1 receptors (AT1R) in all stages of the disease as compared to healthy controls and patients suffering from multiple sclerosis (MS) as a prototype neurologic autoimmune disease. Results As compared to controls, MS patients show higher titers of anti-AT1R antibodies, especially in individuals with active disease. In HD, anti-AT1R antibodies are more frequent than in healthy controls or even MS and occur in 37.9% of patients with relevant titers ≥ 20 U/ml. In a correlation analysis with clinical parameters, the presence of AT1R antibodies in the sera of HD individuals inversely correlated with the age of onset and positively with the disease burden score as well as with smoking and infection. Conclusions These data suggest a dysfunction of the adaptive immune system in HD which may be triggered by different stimuli including autoimmune responses, infection and possibly also smoking.

description: Measurements of the evolution of the magnetic moment of nonideal (i.e. pinning rich) type II superconductors in stationary magnetic fields H a as a function of time at constant temperatures T < Tc or as the temperature is varied to or from Tc provide insight into the dynamics of flux lines and their interactions with the pinning sites. Three concentric magnetic moments coexist in these materials when the isothermal sweep of Ha causes the locus of the magnetization 〈M〉 to migrate along any path joining the upper with the lower envelopes of the major hysteresis curves. The "outermost" magnetic moment is always diamagnetic and is generated by the field opposing Meissner surface current. The two other magnetic moments fill the bulk of the specimen, currents circulating in one direction in the outer annular volume embrace an inner volume occupied by counter-rotating persistent currents. In semi-reversible type II superconductors the magnitude of the Meissner magnetic moment is important compared to that arising from the currents in the bulk whereas in very hysteretic specimens it is negligible. In both types of material it is a fairly straightforward procedure to establish configurations in various static Ha where the opposing magnetic moments exactly cancel each other so that the macroscopic net magnetization is zero. However the internal pattern of persistent currents and magnetic flux density profiles which prevail in these special 〈M〉 = 0 states is complicated, fascinating and provides a full crucible for the investigation of flux line behaviour. In this thesis I present the results of our experimental study of the evolution of the magnetization of these initial 〈M〉 = 0 states during warming to Tc as a function of the static applied field H a. The phenomena encountered are seen to depend dramatically on the direction of the change of Ha causing 〈M〉 to migrate from one envelope of the major hysteresis loop to the opposite. Further we find major differences in the behaviour exhibited by the semi-reversible type II superconductors in comparison with that manifested by the highly hysteretic samples. We also see that the low Tc and high Tc semi-reversible specimens display very similar but highly intricate behaviour. Finally we show that a simple model which exploits the critical state concept and applies the principle of conservation of flux lines can account for the major features of all our observations.

description: MACC1 (Metastasis Associated in Colon Cancer 1) is a key driver and prognostic biomarker for cancer progression and metastasis in a large variety of solid tumor types, particularly colorectal cancer (CRC). However, no MACC1 inhibitors have been identified yet. Therefore, we aimed to target MACC1 expression using a luciferase reporter-based high-throughput screening with the ChemBioNet library of more than 30,000 compounds. The small molecules lovastatin and rottlerin emerged as the most potent MACC1 transcriptional inhibitors. They remarkably inhibited MACC1 promoter activity and expression, resulting in reduced cell motility. Lovastatin impaired the binding of the transcription factors c-Jun and Sp1 to the MACC1 promoter, thereby inhibiting MACC1 transcription. Most importantly, in CRC-xenografted mice, lovastatin and rottlerin restricted MACC1 expression and liver metastasis. This is—to the best of our knowledge—the first identification of inhibitors restricting cancer progression and metastasis via the novel target MACC1. This drug repositioning might be of therapeutic value for CRC patients.
Managing the Canadian mosaic: Dealing with cultural diversity during the WWII years
Creators: name: Caccia, Ivana
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2006
Subjects: subject: History, Canadian.
subject: Canadian Studies.

description: The thesis examines the public discourse on race, foreignness, ethnic diversity, inclusion of "new Canadians" in the Canadian national community, and the meaning of "Canadianism" during the WWII years, from 1939 to 1945, and maps the dialectic course of its construction by the Canadian mainstream intellectual and political elite (mostly Anglo-Saxon and Protestant) and the Liberal government in place. The pre-WWII years were marked by noteworthy official disinterest in "Canadianizing" newcomers and by a latent "racialization" of diversity mostly articulated on the basis of "foreignness" or cultural "strangeness" of so-called "racial" origins of non-British and non-French immigrants. With the outset of war, the "we vs. they" polarization, until then specifically implying on the political scene the British vs. French dualism, began to refer as well to a rather different tension in power relations, generated by the "Canadian born" vs. resident "foreign born" or "immigrant" dichotomy. The meaning of this duality briefly shifted to signify the potential distinction between "loyal citizen" and "enemy alien". Fascist or communist ideological leanings and strong nationalist feelings for the fate of the embattled homelands in Europe further exasperated this tension. In the heat of the WWII years, the Canadian government hired Tracy Philipps---an Englishman with expertise in colonial, Middle-Eastern and East-European affairs---to act as an adviser in its endeavours to secure loyalty and support for its war efforts among Canadians of continental European origin, to mitigate the adversarial relationship among various cultural groups, and to encourage faster assimilation of "new Canadians". To this end, the government set up the Committee on Cooperation in Canadian Citizenship and established the Nationalities Branch within its Department of National War Services, with Philipps as its European Adviser. The thesis explores the subsequent changes in the discursive practice created by the mediation of different ideological approaches brought forward by Philipps, various politicians and adult educators in their search to recognize and define what constituted being a "citizen", a "foreigner"---and, most of all, a "Canadian". The debates accelerated the process of common national self-identification and the emergence of a new institution of "Canadian citizenship". The resulting new discourse affirmed the idea that Canada was a national unit with, nevertheless, an inherent diversity that can be contained and managed if that management were entrusted in the state authority as guarantor of the equality of all its citizens.

description: Background: Given the high levels of sedentary time and treatment-related side effects in prostate cancer survivors (PCS), interventions targeting sedentary behavior (SED) may be more sustainable compared to physical activity (PA). Purpose: To examine the feasibility of a web-based intervention (RiseTx) for reducing SED and increasing moderate-to-vigorous physical activity (MVPA) among PCS undergoing ADT. Secondary outcomes include changes in SED, MVPA, light intensity PA, and quality of life. Methods: Forty-six PCS were recruited from two cancer centres in Toronto, Ontario, Canada between July 2015–October 2016. PCS were given an activity tracker (Jawbone), access to the RiseTx website program, and provided with a goal of increasing walking by 3000 daily steps above baseline levels over a 12-week period. A range of support tools were progressively released to reduce SED time (e.g., self-monitoring of steps) during the five-phase program. Objective measures of SED, MVPA, and daily steps were compared across the 12-week intervention using linear mixed models. Results: Of the 46 PCS enrolled in the study, 42 completed the SED intervention, representing a 9% attrition rate. Measurement completion rates were 97 and 65% at immediately post-intervention and 12-week follow-up for all measures, respectively. Overall adherence was 64% for total number of logins (i.e., > 3 visits each week). Sample mean age was 73.2 ± 7.3 years, mean BMI was 28.0 ± 3.0 kg/m2, mean number of months since diagnosis was 93.6 ± 71.2, and 72% had ADT administered continuously. Significant reductions of 455.4 weekly minutes of SED time were observed at post-intervention (p = .005). Significant increases of + 44.1 for weekly minutes of MVPA was observed at immediately post-intervention (p = .010). There were significant increases in step counts of + 1535 steps from baseline to post-intervention (p < .001). Conclusions: RiseTx was successful in reducing SED and increasing MVPA in PCS. PCS were satisfied with the intervention and its components. Additional strategies may be needed though for maintenance of behavior change. The next step for RiseTx is to replicate these findings in a larger, randomized controlled trial that will have the potential for reducing sedentary time among PCS.

description: The US EPA estimates ten trillion gallons of untreated stormwater enter US water bodies every year (Denchak, 2022). Our goal was to help central Massachusetts municipalities protect water sources with the natural water capture and filtration of rain gardens. Realizing our goal took nine expert interviews, three site visits, and coordination with our sponsor, Emma Williamson, Auburn Town Engineer, and the Central Massachusetts Regional Stormwater Coalition. Through our research we developed a guide on building rain gardens, accompanying educational materials, and built a rain garden at Auburn’s Senior Center. Our garden is Auburn’s test case, with potential success helping persuade Auburn government and residents about the utility and value of rain gardens.

description: This PhD research investigates the smart city concept, its connection to the future of cities, and how to operationalise these in city designing practice. The smart city concept is explored through reviewing literature, a digital review of Australian built environment research groups, interviews and focus groups with Melbourne-based architects, urban planners, urban designers and engineers. Findings show that smarter cities and smarter approaches help create more sustainable and liveable urban futures. Urban agents - designers, academia, governments, citizens and industry - have collective responsibility to establish better future cities. The created conceptual framework can help designers apply smart approaches for urban transformation.

description: This thesis contains a detailed investigation of the dynamics of galaxies in a cosmic epoch where many important evolutionary processes occur. To do this, I used sophisticated observational techniques to measure the amount of rotation in these systems. This way I made a thorough examination of the characteristics of the data and provided suggestions for future studies that use similar datasets and similar techniques. By building up a large sample of galaxies with detailed observations, I also found interesting trends, which will benefit from further studies by scientists working in the field.
Effects of microwave irradiation on the characteristics and mesophilic anaerobic digestion of sequencing batch reactor sludge

description: Wastewater treatment generates large quantities of sewage sludge whose disposal is expensive. Mainly because anaerobic digestion produces methane, which can be beneficially used as an energy source, this process has become the most popular means of stabilizing sewage sludge prior to spreading on agricultural land or disposal to landfills. Several pretreatment technologies have recently been developed to render sludge more degradable during anaerobic digestion. The purpose of this study is to investigate whether microwave irradiation can enhance the anaerobic degradability of aerobic sequencing batch reactor sludge. Relationships relating microwave irradiation duration, microwave intensity, sludge concentration and the temperature reached by the sludge were developed. Sludge concentration in the 1.2-4.3% total solids range was found not to impact the temperature reached by the sludge. Three techniques were used to assess the impact of microwave irradiation on the size of the particles: visual analysis of sludge settling, microscopic analysis and particle size distribution analysis.

The Magic System: An ambient edutainment system for the young children
Creators: name: Karime, Ali
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2009
Subjects: subject: Engineering, Electronics and Electrical.

description: This thesis presents an ambient edutainment system that targets the young children and helps them gain knowledge while having fun. The main idea of the system is that children will learn about new objects by either spelling the names of these objects or by tapping over them, and get in response a set of multimedia output related to these objects. For this purpose, we have implemented two approaches. The first approach is based on a voice recognition engine that detects children's speech, maps their unclear words to an appropriate pre-defined match, and provides the system with an accurate term in order to retrieve the appropriate media. Now the second approach is based on the concept of tangible computing. For this purpose, we designed a tangible user interface called "Magic Stick" that reads the tag identifications attached to entities and objects, and then maps them to their pre-defined terms. We incorporated three games that allow children of different ages to benefit from the system's functionalities and encourage them to interact with it.

description: Exploring the intersection of data sharing and privacy, this research pioneers a blockchain-based system to facilitate data exchange. The proposed framework provides individuals with a mechanism to share or monetize their data without compromising privacy, serving both public and individual benefit. Additionally, by integrating incentive mechanisms, our approach motivates the sharing of high-quality data while enhancing individual control over the data, thereby promoting cross-sector collaboration and facilitating data-driven decision-making in crucial sectors like healthcare and finance. We identified gaps in existing privacy-preserved technologies and developed solutions, aiming to build a foundation for future trustworthy data sharing innovations.

description: Background European chemicals management aims to protect human health and the environment from legacy and emerging contaminants. The plasticizer market changed in response to the restriction of low molecular weight (LMW) phthalate plasticizers such as Di (2-ethylhexyl) phthalate (DEHP) due to their hazardous properties. We investigated patterns and trends of 19 regulated and emerging plasticizers in house dust from German homes and in suspended particulate matter (SPM) from major German rivers. The samples were used from the mid-2000s and late 2010s from two governmental long-term monitoring programs in Germany. Results While the sum of the respective plasticizer levels hardly changed over the study period, we observed a significant decrease of LMW phthalates in both house dust (2003/06, 80% of the (Sigma)plasticizer concentration; 2014/17, 31%) and SPM (2005, 48%; 2017, 28%). This was accompanied by their substitution with high molecular weight (HMW) phthalates and non-phthalates. HMW phthalates increased from 19% of the (Sigma)plasticizer concentration to 46% between the mid-2000s and the late 2010s in house dust, and from 50% to 63% in SPM samples. Diisononyl phthalate (DINP) replaced DEHP as the dominant plasticizer in both compartments. A significant tenfold increase (p<0.05) was observed in SPM samples for Di (2-propylheptyl) phthalate (DPHP) (1-13%), compared to low levels in house dust (2014/17, 1%). Non-phthalates increased to 23% of the (Sigma)plasticizer concentration in house dust but only to 9% in SPM (mid-2000s: house dust,<1%; SPM, 1.5%). In recent house dust samples, Di (2-ethylhexyl) terephthalate (DEHT) had the third highest concentration of all plasticizers and contributed 18% to the total load, whereas Tris (2-ethylhexyl) trimellitate (TOTM) was one of the major non-phthalates in SPM samples. Conclusions Unlike in the indoor environment, the substitution of LMW phthalates in the aquatic environment was characterized by a significant shift towards plasticizers with potentially hazardous properties. DPHP and TOTM were identified by European chemical regulation as potentially endocrine disrupting compounds and persistent, bioaccumulative and toxic compounds. Our data document the need for integrated chemicals management to safeguard the transition to a non-toxic environment. © The Author(s) 2022

description: Dinosaur remains from the Arabian subcontinent are exceedingly rare, and those that have been documented manifest indeterminate affinities. Consequently the discovery of a small, but diagnostic, accumulation of elements from Campanian-Maastrichtian (∼75 Ma) deposits in northwestern Saudi Arabia is significant because it constitutes the first taxonomically identifiable dinosaur material described from the Arabian Peninsula. The fossils include a series of possible lithostrotian titanosaur caudal vertebrae, and some isolated theropod marginal teeth that share unique character states and metric parameters (analyzed using multivariate statistical methods) with derived abelisaurids – this is the first justifiable example of a non-avian carnivorous dinosaur clade from Arabia. The recognition of titanosaurians and abelisaurids from Saudi Arabia extends the palaeogeographical range of these groups along the entire northern Gondwanan margin during the latest Cretaceous. Moreover, given the extreme paucity of coeval occurrences elsewhere, the Saudi Arabian fossils provide a tantalizing glimpse into dinosaurian assemblage diversity within the region.

description: Die Umweltprobenbank des Bundes (UPB) hat das Ziel, biologische Proben aus der Umwelt und vom Menschen über lange Zeit veränderungsfrei zu lagern, um sie für zukünftige Forschung zu archivieren. Sie bietet die einzigartige Möglichkeit, die Belastung der Umwelt und des Menschen über einen langen Zeitraum zu verfolgen. Die UPB wurde parallel zur Erarbeitung des ersten deutschen Chemikaliengesetzes in den 1970er-Jahren konzipiert. Im Jahr 1979 begann sie ihren Probebetrieb. Nachdem 1982 das Chemikaliengesetz in Kraft trat, begann die UPB 1985 ihren dauerhaften Regelbetrieb. Mit der europäischen Chemikalienverordnung REACH wurde 2007 die Verantwortung für die Sicherheit der vermarkteten Chemikalien und die Aufgabe der Risikobewertung maßgeblich der Industrie übertragen. Seitdem ist die UPB noch wichtiger geworden, um die eigenverantwortliche Bewertung der Industrie zu überprüfen, den Erfolg von Minderungsmaßnahmen zu evaluieren und damit letztlich den Schutz von Mensch und Umwelt vor schädlichen Umwelteinflüssen sicherzustellen. Dies geschieht durch regelmäßige Beobachtung der Belastungen und Analyse zeitlicher Trends. Die Ergebnisse der UPB dienen heute der Beratung der politischen Entscheidungsträger über die Notwendigkeit, Maßnahmen zu ergreifen. Informationen zur Belastungsprävention werden für die Allgemeinbevölkerung und den öffentlichen Gesundheitsdienst zur Verfügung gestellt. Die UPB ist somit ein wichtiges Monitoringinstrument des Bundesministeriums für Umwelt, Naturschutz, Bau und Reaktorsicherheit und kooperiert mit namhaften Forschungs- und Universitätsinstituten. Das Umweltbundesamt konzeptioniert und steuert die Arbeit der UPB, leitet die wissenschaftliche Auswertung der Daten und bereitet diese für die Umweltpolitik und die Öffentlichkeit auf.

description: Background: Public health and primary care are distinct sectors within western health care systems. Within each sector, work is carried out in the context of organizations, for example, public health units and primary care clinics. Building on a scoping literature review, our study aimed to identify the influencing factors within these organizations that affect the ability of these health care sectors to collaborate with one another in the Canadian context. Relationships between these factors were also explored. Methods: We conducted an interpretive descriptive qualitative study involving in-depth interviews with 74 key informants from three provinces, one each in western, central and eastern Canada, and others representing national organizations, government, or associations. The sample included policy makers, managers, and direct service providers in public health and primary care. Results: Seven major organizational influencing factors on collaboration were identified: 1) Clear Mandates, Vision, and Goals; 2) Strategic Coordination and Communication Mechanisms between Partners; 3) Formal Organizational Leaders as Collaborative Champions; 4) Collaborative Organizational Culture; 5) Optimal Use of Resources; 6) Optimal Use of Human Resources; and 7) Collaborative Approaches to Programs and Services Delivery. Conclusion: While each influencing factor was distinct, the many interactions among these influences are indicative of the complex nature of public health and primary care collaboration. These results can be useful for those working to set up new or maintain existing collaborations with public health and primary care which may or may not include other organizations.

description: Abstract Mid-hindbrain malformations can occur during embryogenesis through a disturbance of transient and localized gene expression patterns within these distinct brain structures. Rho guanine nucleotide exchange factor (ARHGEF) family members are key for controlling the spatiotemporal activation of Rho GTPase, to modulate cytoskeleton dynamics, cell division, and cell migration. We identified, by means of whole exome sequencing, a homozygous frameshift mutation in the ARHGEF2 as a cause of intellectual disability, a midbrain- hindbrain malformation, and mild microcephaly in a consanguineous pedigree of Kurdish-Turkish descent. We show that loss of ARHGEF2 perturbs progenitor cell differentiation and that this is associated with a shift of mitotic spindle plane orientation, putatively favoring more symmetric divisions. The ARHGEF2 mutation leads to reduction in the activation of the RhoA/ROCK/MLC pathway crucial for cell migration. We demonstrate that the human brain malformation is recapitulated in Arhgef2 mutant mice and identify an aberrant migration of distinct components of the precerebellar system as a pathomechanism underlying the midbrain-hindbrain phenotype. Our results highlight the crucial function of ARHGEF2 in human brain development and identify a mutation in ARHGEF2 as novel cause of a neurodevelopmental disorder. Author summary During brain development, localized gene expression is crucial for the formation and function of specific brain regions. Various groups of proteins are known to regulate segmentation through controlled gene expression, among them, the Rho GTPase regulator family. In this study, we identified a frameshift mutation in the Rho guanine nucleotide exchange factor 2 gene (ARHGEF2) in two children presenting with intellectual disability, mild microcephaly, and a midbrain- hindbrain malformation. This phenotype is also observed in Arhgef2 mutant mice, highlighting the importance of ARHGEF2 across development of distinct mammalian species. We show that loss of Arhgef2 affects neurogenesis and also cell migration. In addition, we extended the current knowledge of ARHGEF2 expression and its role in early central nervous system development, with special reference to the formation of the precerebellar system. In addition to extensive literature on ARHGEF2, we now provide evidence for its significant role in neuronal migration in brain development and link the gene to human neurodevelopmental disease.
