School-Based Food Programming in the Northwest Territories: Working Towards More than Just Food Security
Creators: name: O'Hare-Gordon, Meagan Ann

Year: 2016
Subjects: food security

description: There are an estimated 370 million culturally diverse Indigenous people worldwide. However, among this cultural diversity, there is one commonality that all Indigenous populations share; disparities across all dimensions of health indicators. Food access is one of primary indicators of health and despite this, Canada’s Indigenous population, especially in the North, remains overrepresented in household food insecurity statistics. This research aims at telling the story of one Northern community, Fort Providence, and the experiences around a school-based wild food program. It is written in the publishable paper format and is comprised of two papers. Drawing from approximately 25 weeks of ethnographic research, the first paper uses Homi Bhabha’s concept of Third Space to explain the unique way that Fort Providence youth navigate their local and global experiences. Using three tangible examples, I explain that the space where the local Dene practises interest with contemporary globalized influences creates a productive and empowering Third Space identity for youth. Drawing further on the ethnographic research, paper two gives a detailed description of the innovative land-based school programming that Deh Gah Elementary and Secondary School offers their students. I explain how the food systems in this community are integral to the overall health and vitality of the people. The six primary outcomes which emerged from engaging with community members display how the programming addresses community-wide cultural continuity and individual cultural identity. Together, these papers demonstrate how food systems are deeply embedded into the overall community health and well-being and exhibit the opportunities and positive impacts that land-based food education has for youth and communities.

description: In the Paleoproterozoic Trans-Hudson Orogen, a well exposed section of mid-crust on Hall Peninsula, southeastern Baffin Island, offers an opportunity to improve our understanding of mid-crustal tectonothermal processes in hot, collisional orogens. Additionally, more robust age constraints on the tectonic history of Hall Peninsula are important for plate tectonic reconstructions of the North Atlantic region. Recent mapping shows that the section comprises Archean crystalline basement overlain by Paleoproterozoic supracrustal rocks, which host felsic plutons on the western peninsula. There is a westward increase in peak metamorphic grade, from amphibolite- to granulite-facies, and three regional deformation events are recognized (D1, 2, 3). Equilibrium phase diagram modeling constrained by garnet compositions in pelite indicates peak conditions of ~720–740°C on the eastern peninsula and ~850°C further west, with pressures of ~6.25–7.35 kbar. Modeling and petrographical evidence suggest subsequent cooling, decompression, growth of retrograde biotite and, on the eastern peninsula, retrograde muscovite. In situ U-Pb monazite dating (~450 analyses) and U-Pb zircon depth profiling (~90 analyses) resolve the timing of regional metamorphism and crustal shortening between ca. 1860–1820 Ma, coincident with the accretion of crustal blocks and arc terranes during the amalgamation of the orogenic upper (Churchill) plate. Regionally-occurring ca. 1800–1750 Ma monazite domains and zircon rims are interpreted to result from fluid-assisted dissolution-reprecipitation. They likely record the terminal collision with the lower-plate Superior craton and post-orogenic thermal activity, possibly related to the emplacement of pegmatitic syenogranite dykes. The new data strengthen formerly tentative correlations with southern Baffin Island, West Greenland and northern Labrador. 40Ar/39Ar thermochronology on muscovite, biotite and phlogopite suggests that Hall Peninsula underwent slow cooling at rates of ~1–2.5ºC/Myr after peak metamorphism, remaining hotter than ~400°C until ca. 1670–1660 Ma. Analogous thermochronological ages from elsewhere in the Trans-Hudson Orogen imply orogen-wide slow cooling. Despite significant crustal thickening and elevated paleotemperatures, the Hall Peninsula crustal section does not record evidence of orogenic collapse, implying that it may not be a hallmark of all hot, thickened orogens.

description: Despite improvements in chemotherapy and radical surgical debulking, peritoneal carcinomatosis (PC) remains among the most common causes of death for abdominal cancers. Immunotherapies have demonstrated efficacy in selected solid malignancies but their potential in PC is poorly explored. Here I report that intraperitoneal injection of an infected cell vaccine (ICV), consisting of autologous tumor cells infected ex-vivo with an oncolytic Maraba MG1 virus expressing interleukin-12 (IL-12), promotes the migration of activated natural killer (NK) cells to the peritoneal cavity in response to the secretion of interferon gamma-induced protein-10 (IP-10) from dendritic cells. This recruitment of cytotoxic, IFNγ-secreting NK cells is associated with a dramatic reduction in tumor burden and improved survival in a colon cancer model of PC. Even in mice with bulky PC (tumors >8 mm), a complete radiological response was demonstrated within 8-14 weeks, associated with 100% long-term survival. Importantly, these results were recapitulated in human lymphocytes exposed to human tumor cell lines infected with MG1-IL12. Finally, I demonstrate that MG1-IL12-ICV generates an effective CD4 and CD8 T cell response in mice following prophylactic immunization associated with the maturation of peritoneal dendritic cells and enrichment of tumor-specific peritoneal T cells. The research presented in this thesis suggests that an MG1-IL12-ICV is a promising therapy that could provide benefit to the thousands of patients diagnosed with PC each year.

Amphiphilic block copolymers

description: Fluoropolymers are a versatile and attractive group of compounds having an interesting mix of properties that make them highly useful for various applications. Because of strong bonding between the carbon and fluorine atom, they exhibit unique physical and chemical properties such as high thermal stability, increased chemical resistance, low refractive index, enhanced inertness towards many solvents and hydro-compounds. These characteristics have led them to be widely used in aerospace, aeronautics, optics, microelectronics, paints and coatings, and engineering structures and as biomaterials. Amphiphilic copolymers possess unique solution and solid-state properties due to their well-defined molecular architecture. These properties arise as the result of covalently combining two thermodynamically different polymer blocks that phase separate on the nanoscale. Amphiphilic copolymers based on a fluoro-monomer will combine the favourable physiochemical properties of the desired fluorine segment in combination with complementary hydrophilic segments. Such fluorinated amphiphilic copolymers are potentially useful for drug delivery vehicles and membrane applications. This project is aimed at making fluorinated amphiphilic block copolymers of hydrophobic 2, 3, 4, 5, 6 –pentafluorostyrene (PFS) and hydrophilic methacrylic acid (MAA). A controlled radical polymerization mechanism, nitroxide mediated polymerization (NMP) using NHS-BlocBuilder as the initiator was employed. The advantage of using NMP is that it facilitates the synthesis of copolymers with well-controlled narrow molecular weight distribution. However, methacrylate homopolymerization by NMP is challenging due to the high dissociation equilibrium constant therefore, the use of PFS as a controlling comonomer was explored. We established that to obtain a controlled copolymerization, a minimum of 70 mol% PFS was required, which is significantly greater than other copolymerization systems such as using as little as 4.5-8 mol% styrene to control the copolymerization of MAA. We surmise that this lack of control is due to the unfavourable reactivity ratios (Appendix I) which favour the addition of MAA rather than PFS (rPFS = 0.012, rMAA = 8.12). However, these unique reactivity ratios suggest that a semi-batch approach can be utilized to synthesize almost pure block copolymers in one pot. Therefore, poly(PFS)–b-(PFS-ran-MAA) block copolymers were synthesized and characterized by a semi batch addition of MAA. While successful, the concentration of irreversibly terminated chains was evident and greater care in reducing these unwanted reactions needs to be addressed.

description: One of the major research challenges is the ability to test selective forces in a wild population. A recent discovery of a new dipteran species, Protopiophila litigata, can enable researches to test selection in the wild. Most research has focused on mating behaviour, male mating success and senescence. In this study a small sample of wild mating and non-mating flies were collected, cuticular hydrocarbons were extracted and morphometric traits were obtained to assess the strength of sexual selection. There was significant linear sexual selection on cuticular hydrocarbons and, mid tibia length, hind tibia length and wing length. Overall, further establishes P. litigata as a model species for studying selection in the wild. Earlier studies have demonstrated strong sexual selection on male cuticular hydrocarbons in Drosophila serrata. Recently wing interference patterns have been documented to be under sexual selection in Drosophila melanogaster. A sample of cuticular hydrocarbons and wing interference pattern values were analyzed to understand the combined effects on male mating success. Cuticular hydrocarbons were under sexual selection, however wing interference patterns were not. Overall, this study confirms selection on cuticular hydrocarbons, but highlights the difficulty in accurately capturing and measuring wing interference patterns.

description: Gentrification is popularly defined as a trend in the development of urban neighbourhoods that results in increased property values, and the displacement of lower-income families and existing small businesses. As a way of developing neighborhoods through urban projects, private development companies argue that the “ends justify the means” in their quest to “renew” and “revitalize” a “blighted” neighbourhood. This thesis asks what happens to those in the footprint of a development project. Taking a 22-acre multi-use urban megaproject in Brooklyn as a privileged site for inquiry, it documents and analyzes the experience of residents in initial and subsequent phases of the development process. Drawing on fieldwork and interviews with 28 individuals, the thesis argues that gentrification can be better understood by conceptualizing the social relations involved, in particular, those of corruption and community.

description: Objectives: The purpose of this study was to investigate the effect of an 8-week aerobic exercise program on daily energy expenditure and intake in adolescents with normal-weight and with overweight or obesity. Methods: Prospective intervention study. The study included twenty-six adolescents aged between 14-18 years: 17 adolescents (8 girls and 9 boys) with normal-weight (BMI <85th percentiles for age and sex), and 9 adolescents (5 girls and 4 boys) with overweight or obesity (BMI 85th percentile for age and sex). The aerobic exercise program included 30 minutes of cycling performed on a Monark cycle ergometer 3 times a week for 8 weeks at an exercise target heart rate at 75% of participants’ heart rate reserve using the Karvonen formula. Total daily energy expenditure was measured with an indirect calorimeter wear for resting metabolic rate and a 7-day accelerometer for energy expenditure from physical activity. Energy intake was estimated with 24-hour recalls. Results: The aerobic exercise program did not have any significant effect on body weight. Significant effects of aerobic exercise on total daily energy expenditure (p=.051), energy expenditure from physical activity (p=.031) and total daily energy intake (p=.008) were observed, which mainly revealed a reduction in daily physical activity and energy intake following the exercise program. However, there was no significant effect of weight status and no interaction effect between of aerobic exercise and weight status for those three variables. Conclusions: Adolescents with normal weight, overweight or obesity not only reduced their daily total energy expenditure by reducing physical activity, but simultaneously decreased their total daily energy intake after an aerobic exercise program.

description: Coronary artery disease (CAD) is the leading cause of death worldwide caused by a complex array of environmental and genetic factors. In recent years, the CARDIoGRAM Consortium has identified dozens of novel CAD-associated loci, including COL4A1/COL4A2 and SMAD3. The goals of this project were two-fold. First, to identify functional CAD-associated SNPs (single nucleotide polymorphisms) at these loci and investigate how these common polymorphisms alter CAD risk. Second, to determine if the COL4A1/COL4A2 and SMAD3 loci display both biological interaction and statistical interaction in the context of atherosclerosis. COL4A1 and COL4A2 are critical components of vascular basement membranes and have many additional roles in the vessel wall. SMAD3 is a transcription factor that is a key mediator in the canonical TGFβ signaling pathway. In the first section of this thesis, I show that COL4A1/COL4A2 and SMAD3 display biological interaction in that the TGFβ-mediated upregulation of COL4A1 and COL4A2 is dependent on SMAD3. Furthermore, we were able to identify a COL4A2-SMAD3 SNP pair that displayed a highly significant statistical interaction for CAD association, highlighting that perturbations of the SMAD3/type IV collagen signaling axis contribute to the pathogenesis of atherosclerosis. The second section details the characterization of a novel functional CAD-associated SNP at the SMAD3 locus. The rs17293632 SNP, highly linked to the rs56062135 index SNP reported by CARDIoGRAM, disrupts a conserved AP-1 binding site in intron 1 of the SMAD3 gene. rs17293632 lies within a strong enhancer in many cell types, including arterial smooth muscle cells. The minor, protective allele (T) at rs17293632 disrupts binding of AP-1 proteins, lowers the activity of this enhancer and lowers SMAD3 mRNA levels in humans in both whole blood and carotid plaque tissue. Altogether, AP-1 regulation of SMAD3 enhancer activity suggests a novel regulatory mechanism relevant to the pathogenesis of CAD. The third section summarizes efforts to characterize the mechanisms whereby the independent rs4773144 and rs9515203 SNPs at the COL4A1/COL4A2 locus associate highly with CAD. We were unable to identify causal SNPs at the COL4A1/COL4A2 locus, highlighting the challenges of post-GWAS characterization of some CAD-associated loci. The experiments with SNPs at COL4A1/COL4A2 demonstrate the challenges in defining mechanisms whereby noncoding DNA variants can lead to common disease.

description: This thesis presents a framework capable of integrating hard (physics-based) and soft (people-generated) data for the purpose of achieving increased situational assessment (SA) and effective course of action (CoA) generation upon risk identification. The proposed methodology is realized through the extension of an existing Risk Management Framework (RMF). In this work, the RMF’s SA capabilities are augmented via the injection of soft data features into its risk modeling; the performance of these capabilities is evaluated via a newly-proposed risk-centric information fusion effectiveness metric. The framework’s CoA generation capabilities are also extended through the inclusion of people-generated data, capturing important subject matter expertise and providing mission-specific requirements. Furthermore, this work introduces a variety of CoA-related performance measures, used to assess the fitness of each individual potential CoA, as well as to quantify the overall chance of mission success improvement brought about by the inclusion of soft data. This conceptualization is validated via experimental analysis performed on a combination of real- world and synthetically-generated maritime scenarios. It is envisioned that the capabilities put forth herein will take part in a greater system, capable of ingesting and seamlessly integrating vast amounts of heterogeneous data, with the intent of providing accurate and timely situational updates, as well as assisting in operational decision making.

description: The carbonate storm-dominated sedimentary succession superbly exposed on Anticosti Island in Eastern Canada represents one of the most complete and well-preserved paleotropical stratigraphic records spanning the Ordovician-Silurian (O-S) boundary. We sampled the nearly continuous coastal outcrop exposed at low tide along the west coast of Anticosti Island for high-resolution δ13C and δ18O chemostratigraphy. These new isotopic curves comprise more than 500 data points spaced at ~0.6 m intervals; for a total of 320 m of strata across the O-S boundary. The δ13C curve displays two distinctive positive excursions in the Hirnantian Ellis Bay Formation; a small lower excursion (+2.5‰) and an upper larger excursion (+4.5‰). These two positive isotopic carbon excursions provide a distinctive chemostratigraphic signature for regional and global correlations with other Hirnantian sections. The continuing descending δ13C trend, at least 30 m above the currently interpreted O-S boundary, suggests a readjustment of that boundary on the Anticosti succession. The δ18O curve, similarly to the Quaternary δ18O marine curve, is tightly coupled with multi-order cyclic facies changes. Our tightly coupled lithological and oxygen isotopic data suggest that the Anticosti succession was influenced by glacio-eustatic fluctuations during the end-Ordovician. Furthermore, the estimated duration of these multi-order cycles supports an astronomical forcing. A primary isotopic signal record is also supported by the lack of significant covariance between δ13C and δ18O, by the excellent microfabric preservation of both macro and microfossils in petrographic, cathodoluminescence, and SEM microscopy, and by little or no diagenetic resetting as suggested by the trace element geochemistry, which is unusual in the deep geological time.

description: The future of Alberta’s bitumen sands, also known as “oil sands” or “tar sands,” and their place in Canada’s energy future has become a topic of much public debate. Within this debate, the print, television, and social media campaigns of those who both support and oppose developing the oil sands are particularly visible. As such, campaigns around the oil sands may be seen as influencing audience perceptions of the benefits and drawbacks of oil sands production. There is consequently a need to study the media materials of various tar sands stakeholders and explore how they differ. In this setting, it is essential to gather documents and identify content within images, which requires the use of an image retrieval technique such as a content-based image retrieval (CBIR) system. In a CBIR system, images are represented by low-level features (i.e. specific structures in the image such as points, edges, or objects), which are used to distinguish pictures from one another. The oil sands domain has to date not been mapped using CBIR systems. The research thus focuses on creating an image retrieval system, namely Mediatoil-IR, for exploring documents related to the oil sands. Our aim is to evaluate various low-level representations of the images within this context. To this end, our experimental framework employs LAB color histogram (LAB) and speeded up robust features (SURF) in order to typify the imagery. We further use machine learning techniques to improve the quality of retrieval (in terms of both accuracy and speed). To achieve this aim, the extracted features from each image are encoded in the form of vectors and used as a training set for learning classification models to organize pictures into different categories. Different algorithms were considered such as Linear SVM, Quadratic SVM, Weighted KNN, Decision Trees, Bagging, and Boosting on trees. It was shown that Quadratic SVM algorithm trained on SURF features is a good approach for building CBIR, and is used in building Mediatoil-IR. Finally, with the help of created CBIR, we were able to extract the similar documents and explore the different types of imagery used by different stakeholders. Our experimental evaluation shows that our Mediatoil-IR system is able to accurately explore the imagery used by different stakeholders.

description: Liquid storage tanks are a crucial type of structures. They are used to store various types of liquids and liquefied gases in different situations. In seismic regions, functionality of these structures after severe earthquakes is an important factor in their design. In earthquake-prone regions, the sloshing phenomena has an important role in the design procedure. Current design codes and guidelines (e.g. ACI 350.3 and ASCE 7) are based on analytical studies that in some cases can be inaccurate in prediction of forces and pressures. Since a long time ago scientists have studied the sloshing phenomena in liquid storage tanks with different methods including analytical, numerical and experimental studies. In the current study, rectangular ground-supported tanks are studied and the effect of seismic loading on them is investigated both experimentally and numerically. For the experimental tests, the tanks were placed on a shaking table and using high-speed HD cameras, tests were filmed and later analyzed frame by frame to capture the critical moments. To investigate the bi-lateral effect of base excitation on the tanks, they were oriented on the table with four different angles. In the numerical study, a computational fluid dynamics tool - OpenFOAM - was used to simulate the tank motion and finally the results were compared with the experiment in order to develop a reliable model.

description: The recent discovery of adult neural precursor cells (NPCs) in the dentate gyrus and the subventricular zone of the lateral ventricles of most mammals holds much hope for the potential regeneration of damaged brain tissue. However, their use has been limited by their low numbers and relatively quiescent state, particularly in the aging brain. Previous studies from our laboratory have demonstrated a crucial role for the Rb/E2F pathway in the regulation and proliferation of NPCs, and the direct mechanistic involvement of E2F3 in regulating the pluripotency factor, Sox2. More recently, our investigations into the roles of E2F1 and E2F3 in during adult neurogenesis have revealed that loss of both these genes results in a dramatic loss of adult NPCs. Here, we have employed the Emx1-Cre and Nestin-CreERT2 transgenic models, to specifically delete E2F1 and E2F3 in the cerebral cortex and in NPCs in order to investigate the role of both these genes in embryonic neurogenesis. Our results suggest a switch in the requirement for both E2Fs 1 and 3 between embryonic and adult NPCs, demonstrated by a decrease in NPC proliferation and numbers starting only during late embryonic development and persisting through postnatal neurogenesis. These findings suggest that E2Fs 1 and 3 are essential for the maintenance of stem cells and neurogenesis in the adult brain. Moreover, their deletion results in defects in learning and memory. These studies reveal a crucial role for activating E2Fs in the long-term maintenance and proliferation of neural stem cells.

description: In 2007, one current and two former sex workers, Amy Lebovitch, Terri-Jean Bedford and Valerie Scott launched a charter challenge, Bedford v Canada, arguing that the prostitution provisions criminalizing bawdy houses (section 210), living on the avails (section 212 (1)(j)) and communicating for the purposes of prostitution (section 213.1 (c)) violated their section 7 rights under the Charter of Rights and Freedoms. Six years later, the Supreme Court of Canada ruled unanimously to strike down all three challenged laws, leaving a one-year period to construct a new regime on prostitution. On December 6, 2014, the Protection of Communities and Exploited Persons Act (PCEPA) came into effect, criminalizing, for the first time, prostitution in Canada and introducing a law that replicates many of the provisions of the previous regime. This thesis uses semi-structured interviews and qualitative analysis to examine the experiences of nine street-based sex workers in Ottawa, paying particular attention to experiences after the introduction of the new law. Drawing on the work of Mead & Blumer’s symbolic interactionism theory and Goffman’s concept of stigma the thesis examines how embedded stereotypes in legislation ‘play out’ in the lives of sex workers. I argue that the interactions of sex workers in Ottawa are conditioned by stereotypical assumptions which in turn lead to their broader discrimination and marginalization. This study concludes by finding that the first objective of PCEPA, to protect those who sell their own sexual services, has not been met; instead, PCEPA has resulted in street-based sex workers in Ottawa assuming more risk, and in turn, facing more danger while on the job.

description: Flight across the North Atlantic is a routine process now, with thousands of flights carrying millions of passengers between Europe and North America every year quickly, safely, and affordably. By some measures it remains the busiest international flight corridor in the world and the most profitable for airlines. Yet there were no planes capable of making the flight a mere century ago. Aviation underwent a period of rapid development and expansion during the twentieth century that transformed the North Atlantic from a barrier into a central corridor in the global air network. This dissertation examines the development of civil aviation on the North Atlantic from 1919 to 1970, focusing on political, economic, and technological factors. Transatlantic flight was a focus of aviation but the earliest planes lacked the range needed to make the crossing. Technological improvements let pioneering aviators cross the ocean by 1919, proving that it was possible though difficult without further advances. Infrastructure also needed to be further developed since the North Atlantic was a hostile environment, with bad weather and limited facilities for aircraft in emergencies. Until 1945, the governments of the North Atlantic region thoroughly explored, studied, and built the infrastructure to make regular transatlantic possible. Postwar, governments supported their airlines through further infrastructural improvements, subsidies, by funding aeronautics, and by complex negotiations with foreign countries to open the skies to passenger travel. By 1970, transatlantic flight was a routine endeavour enjoyed by the masses and supported by systems invisible to the average traveler.

description: Die wertgebenden Eigenschaften von Bioabfällen aus Haushalten und damit ihr Potenzial liegen in ihrem Gehalt an Pflanzennährstoffen und hier vor allem auch an Phosphor sowie dem Gehalt an nativer Organik bzw. Kohlenstoff. Zu Kompost verarbeitet kann mit dem Einsatz auf Böden ein hoher ökologischer Nutzen verbunden werden. Dies lässt sich ohne Abstriche in der Kompostqualität dann mit einer Energiegewinnung verbinden, wenn eine Biogaserzeugung integriert wird. Verwertungssysteme müssen optimal ausgebildet werden, d. h. hohe Emissionsstandards in Verbindung mit einer hohen Effektivität bspw. auch in der Biogasnutzung. Ist dies gewährleistet, ist die getrennte Sammlung und Verwertung von Bioabfällen unter nahezu allen Umweltgesichtspunkten gegenüber einem Verzicht auf die Biotonne vorteilhaft.Internet: http://www.MUELLundABFALL.de/MA.02.2013.074 04.03.2013

description: The valuable characteristics of household biowaste are the content of plant nutrients, mainly phosphorus, and of native organic matter or carbon. Processed to compost, the application to soils can be of high ecological value. Without losses of compost quality, the process can be combined with energy production if a fermentation is integrated into the concept. Recovery systems have to be designed with optimum effects, combining high emission standards with a high effectivity, e. g. of the biogas exploitation. If this is guaranteed, the separate collection and recovery of biowastes have advantages in almost all environmental aspects compared to systems without biowaste collection.Internet: http://www.MUELLundABFALL.de/MA.02.2013.074 04.03.2013
An action-centred approach to conceptualising information support for routine work

description: In this paper, we continue our long-term project of developing a situated information systems analysis and design methodology, and present it as a radical alternative to conventional information systems analysis and design. Taking a situated approach entails focusing on action and a situated analysis and design methodology aims to increase efficiency and effectiveness through supporting routine action. We suggest that, as well as improving effectiveness and temporal efficiency, applying the situated methodology will result in less wasted human effort expended in search of information. We discuss the implications of an action focus for our conception of what an information system should be, and illustrate the application of the methodology with examples from a case study.

Potential Role for the Sarcolemmal Membrane Associated Protein Isoform 3 (SLMAP3) in Cardiac Remodeling Post Myocardial Infarction
Creators: name: Lefnaier, Wafa

Subjects: Myocardial Infarction

description: ABSTRACT The Sarcolemmal Membrane Associated Protein 3 (SLMAP3) is a tail-anchored membrane protein, which is ubiquitously expressed in tissues including myocardium. It is a component of subcellular membranes and the centrosome, and it appears to serve distinct roles in cell growth and membrane biology. In addition, mutations in SLMAP have been linked to Brugada syndrome, which leads to cardiac dysfunction and death. Here, we have examined the effects of different levels of SLMAP3 on postnatal heart function, pre and post myocardial infarction (MI).Transgenic (TG) mice with a cardiac specific expression of SLMAP3 isoform were generated and assessed with echocardiography to measure function, immunohistochemistry for histology, TUNEL assay for apoptosis, Masson’s trichrome staining for fibrosis, and Western blots for protein expression. Baseline echocardiography of 8 weeks old TG mice showed a normal cardiac function that was expressed in ejection fraction percent (%EF=66%±7.42), which was similar to those of wild type mice (%EF=67%±9.36), p<0.05, n=20-25 (in each group). MI was induced by permanent ligation of left anterior descending (LAD) artery in 9 week old WT & TG mice, while sham was the control. No death was recorded in SLMAP3 TG mice up to one year post MI, whereas 70% of WT mice had deceased, p<0.01, n=17-18 (in each group). Cardiac function was assessed by echocardiography (at 4 week post MI) showed a partially restored ejection fraction percent (%EF~49.2%±17.02) in SLMAP3 TG mice post MI compared to (%EF~36.4%±15.25) in WT mice post MI, p<0.05, n=15-16 (in each group). Furthermore, infarct size (IS) as well as collagen area (CA) post MI were significantly attenuated (IS~43%±8.82, CA~35%±5.15) in SLMAP3 TG myocardium in comparison to WT (IS~53%±9.30, CA~47%±7.36), p<0.05, n=20- 22 (each group). Moreover, expression of the heart failure biomarker galectin3 was markedly ii attenuated (1.8±0.20) in SLMAP3 TG hearts post MI compared to (3.2±0.35) in WT, p<0.01, n=4-5 (in each group). The apoptotic index in SLMAP3 TG myocardium assessed by TUNEL was markedly decreased (77±11.48) in comparison to WT (112±15.32), p<0.05, (n=20-22 in each group). Further, expression of proapoptotic proteins (Caspase3 and Bax) was significantly attenuated in SLMAP3 TG (p<0.05, n=4-5 in each group) while the expression of the prosurvival proteins (Bcl2 and caveolin3) was significantly upregulated (p<0.05, n=4-5 (in each group) in post MI. These data indicate that increased SLMAP3 levels serve to protect myocardium post MI through mechanisms which promote cell survival and limit cardiac fibrosis. Strategies to increase SLMAP3 level in myocardium may provide new therapeutic options in the treatment of heart failure.

description: Introduction: We previously described the manufacture and characterization of hydrogel forming, thin film, anti-infective wound dressings made from Poly Vinyl Alcohol (PVA) and silver nanoparticles, crosslinked by heat. However, these films were designed to be inexpensive for simple manufacture locally in Africa. In this new study, we have further developed PVA dressings by manufacturing films or electrospun membranes, made from blends of PVA with different degrees of hydrolyzation, that contain silver salts and degrade in a controlled manner to release silver in a sustained manner over 12 days. Methods: Films were solvent cast as films or electrospun into nanofibre membranes using blends of 99 and 88% hydrolyzed PVA, containing 1% w/w silver sulphadiazine, carbonate, sulphate, or acetate salts. Dissolution was measured as weight loss in water and silver release was measured using inductively coupled plasma (ICP) analysis. Results: Cast films generally stayed intact at PVA 99: PVA 88% ratios greater than 40:60 whereas electrospun membranes needed ratios greater than 10:90. Films (40:60 blend ratio) and membranes (10:90) all released silver salts in a sustained fashion but incompletely and to different extents. Electrospun membranes gave more linear release patterns in the 2–12 day period and all salts released well. Conclusion: Blended PVA cast films offer improved control over hydrogel dissolution and silver release without the need for high temperature crosslinking. Blended PVA electrospun membranes further improve membrane dissolution control and silver release profiles. These blended PVA films and membranes offer improved inexpensive systems for the manufacture of long lasting anti-infective hydrogel wound dressings.
