Reflections on an Introduction to Project Based Engineering in an Incarcerated Setting

Education programs in incarcerated settings have a goal of improving the current and future lives of the currently incarcerated individuals. There are many programs that support earning a GED, associate degree, or baccalaureate degree when incarcerated. The benefits of these programs include improved behavior while incarcerated, reduced recidivism, and broadening the workforce. Generally, the courses offered as a part of these programs are general education in nature. This paper discusses an Introduction to Project Based Engineering taught in a women’s prison setting. Specifically, it explores the course as a case study reflected on from several angles. Each reflection illuminates the case from a different perspective. The different perspectives are a prison administrator, the instructor, the author of one of the textbooks used in the course, a student more than a decade from release, and a student a few months from release. By taking these reflections together one is able to see the challenges, rewards, and opportunities associated with teaching an Introduction to Project Based Engineering to incarcerated women. Although each perspective highlights different aspects of the course there are common themes. There are also key differences that illustrate the unique needs and wants of the various stakeholders. The common themes and differences are examined. Together they serve as a foundation for adjusting the course to make it more effective and sustainable. Additionally, the reflections examined here shed light on how an Introduction to Project Based Engineering in a traditional setting might be improved

Numerosas condições patológicas associadas à gestação, constituem fatores de risco que podem resultar em possíveis complicações materno-fetais. Nesse contexto, o presente estudo observacional descritivo, apresenta o caso de uma paciente de 24 anos G1P1C1A0, portadora de tumor pancreático, nefropatia membranosa, hipertensão arterial crônica, diabetes mellitus 2, dislipidemia, esteatose hepática e infecção urinária de repetição. Os dados relacionados ao presente estudo foram coletados por meio de análise de prontuários e dos exames laboratoriais e de imagem, após autorização do Comitê de Ética (CAAE: 59909122.4.0000.5076). Com ajuste da terapêutica farmacológica e orientações sobre a alimentação adequada e atividades físicas, a gestação cursou sem complicações até a 36ª semana e 1 dia, quando a paciente deu entrada na emergência obstétrica da Santa Casa de Misericórdia de Anápolis-GO em iminência de eclâmpsia. Na ocasião fora realizado o parto cesáreo sem intercorrências. O recém-nascido do sexo feminino, classificado como pré-termo tardio, apresentou peso de adequado à idade gestacional, valores de APGAR de 7 (1º minuto) e 8 (5 º minuto), sem malformações aparentes. Portanto, nota-se que a implementação de práticas oportunas e adequadas, baseadas em evidências, permite a redução da mortalidade materna e fetal

Hypertension Management Using Mobile Technology and Home Blood Pressure Monitoring: Results of a Randomized Trial in Two Low/Middle-Income Countries

Abstract Objective: Hypertension and other noncommunicable diseases represent a growing threat to low/middle-income countries (LMICs). Mobile health technologies may improve noncommunicable disease outcomes, but LMICs lack resources to provide these services. We evaluated the efficacy of a cloud computing model using automated self-management calls plus home blood pressure (BP) monitoring as a strategy for improving systolic BPs (SBPs) and other outcomes of hypertensive patients in two LMICs. Subjects and Methods: This was a randomized trial with a 6-week follow-up. Participants with high SBPs (≥140?mm Hg if nondiabetic and ≥130?mm Hg if diabetic) were enrolled from clinics in Honduras and Mexico. Intervention patients received weekly automated monitoring and behavior change telephone calls sent from a server in the United States, plus a home BP monitor. At baseline, control patients received BP results, hypertension information, and usual healthcare. The primary outcome, SBP, was examined for all patients in addition to a preplanned subgroup with low literacy or high hypertension information needs. Secondary outcomes included perceived health status and medication-related problems. Results: Of the 200 patients recruited, 181 (90%) completed follow-up, and 117 of 181 had low literacy or high hypertension information needs. The median annual income was $2,900 USD, and average educational attainment was 6.5 years. At follow-up intervention patients' SBPs decreased 4.2?mm Hg relative to controls (95% confidence interval ?9.1, 0.7; p=0.09). In the subgroup with high information needs, intervention patients' average SBPs decreased 8.8?mm Hg (?14.2, ?3.4, p=0.002). Compared with controls, intervention patients at follow-up reported fewer depressive symptoms (p=0.004), fewer medication problems (p<0.0001), better general health (p<0.0001), and greater satisfaction with care (p≤0.004). Conclusions: Automated telephone care management plus home BP monitors can improve outcomes for hypertensive patients in LMICs. A cloud computing model within regional telecommunication centers could make these services available in areas with limited infrastructure for patient-focused informatics support.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/98494/1/tmj%2E2011%2E0271.pd

Molecular Characterization of the Gastrula in the Turtle Emys orbicularis: An Evolutionary Perspective on Gastrulation

Due to the presence of a blastopore as in amphibians, the turtle has been suggested to exemplify a transition form from an amphibian- to an avian-type gastrulation pattern. In order to test this hypothesis and gain insight into the emergence of the unique characteristics of amniotes during gastrulation, we have performed the first molecular characterization of the gastrula in a reptile, the turtle Emys orbicularis. The study of Brachyury, Lim1, Otx2 and Otx5 expression patterns points to a highly conserved dynamic of expression with amniote model organisms and makes it possible to identify the site of mesoderm internalization, which is a long-standing issue in reptiles. Analysis of Brachyury expression also highlights the presence of two distinct phases, less easily recognizable in model organisms and respectively characterized by an early ring-shaped and a later bilateral symmetrical territory. Systematic comparisons with tetrapod model organisms lead to new insights into the relationships of the blastopore/blastoporal plate system shared by all reptiles, with the blastopore of amphibians and the primitive streak of birds and mammals. The biphasic Brachyury expression pattern is also consistent with recent models of emergence of bilateral symmetry, which raises the question of its evolutionary significance

Glycosylation-dependent circuits synchronize the pro-angiogenic and immunoregulatory functions of myeloid-derived suppressor cells in cancer

Myeloid-derived suppressor cells (MDSCs) favor tumorprogression and therapy resistance by reprogramming antitumor immunity and promoting angiogenesis. To elucidatethe mechanisms that synchronize these functions, we investigated the role of glycosylation-dependent, galectin-1(Gal1)-driven circuits in coupling immunoregulatory andpro-angiogenic activities of MDSCs. Flow cytometry andHPLC-HILIC/WAX revealed an activation-dependent glycanprofile in monocytic and polymorphonuclear MDSCs (p=0.03)that controlled Gal1 binding and was more prominent in tumor microenvironments. Exposure to Gal1 led to concomitant activation of immunosuppression and angiogenesisprograms in bone marrow derived MDSCs. Flow cytometryof Gal1-conditioned MDSCs showed higher expression ofimmune checkpoint molecules, including programmed deathligand-1 (PD-L1) (p=0.005) and indoleamine 2,3-dioxygenase (IDO) (p=0.037) and greater production of reactive oxygen species (ROS) and nitric oxide (NO) (p=0.02). In vitro,Gal1-conditioned MDSCs showed greater T-cell suppressive capacity (p=0.03) and higher IL-10 (p=0.04) and IL-27(p=0.003) secretion. These effects were accompanied by enhanced endothelial cell migration, tube formation, 3D-sprouting and vascularization (p<0.05). In vivo, Gal1-conditionedMDSCs accelerated tumor growth (p=0.001) and fosteredimmune evasion and vascularization programs in Gal1-deficient colorectal tumors. Mechanistically, mass spectrometry,immunoblot and blocking assays identified the CD18/CD11b/CD177 complex as a bona fide Gal1 receptor and STAT3 asa key signaling pathway coupling these functions. Accordingly, a combined algorithm that integrates Gal1 expressionand MDSC phenotype, showed critical prognostic value bydelineating the immune landscape and clinical outcome ofhuman cancers. Thus, glycosylation-dependent Gal1-drivencircuits favor tumor progression by coupling immunoregulatory and pro-angiogenic programs of MDSCs via CD18- andSTAT3-dependent pathways.Fil: Blidner, Ada Gabriela.

Arctic hydroclimate variability during the last 2000 years : current understanding and research challenges

Reanalysis data show an increasing trend in Arctic precipitation over the 20th century, but changes are not homogenous across seasons or space. The observed hydro-climate changes are expected to continue and possibly accelerate in the coming century, not only affecting pan-Arctic natural ecosystems and human activities, but also lower latitudes through the atmospheric and ocean circulations. However, a lack of spatiotemporal observational data makes reliable quantification of Arctic hydroclimate change difficult, especially in a long-term context. To understand Arctic hydroclimate and its variability prior to the instrumental record, climate proxy records are needed. The purpose of this review is to summarise the current understanding of Arctic hydroclimate during the past 2000 years. First, the paper reviews the main natural archives and proxies used to infer past hydroclimate variations in this remote region and outlines the difficulty of disentangling the moisture from the temperature signal in these records. Second, a comparison of two sets of hydroclimate records covering the Common Era from two data-rich regions, North America and Fennoscandia, reveals inter- and intra-regional differences. Third, building on earlier work, this paper shows the potential for providing a high-resolution hydroclimate reconstruction for the Arctic and a comparison with last-millennium simulations from fully coupled climate models. In general, hydroclimate proxies and simulations indicate that the Medieval Climate Anomaly tends to have been wetter than the Little Ice Age (LIA), but there are large regional differences. However, the regional coverage of the proxy data is inadequate, with distinct data gaps in most of Eurasia and parts of North America, making robust assessments for the whole Arctic impossible at present. To fully assess pan-Arctic hydroclimate variability for the last 2 millennia, additional proxy records are required.Peer reviewe

A lake as a microcosm: reflections on developments in aquatic ecology

In the present study, we aim at relating Forbes' remarkable paper on "The lake as a microcosm", published 125 years ago, to the present status of knowledge in our own research group. Hence, we relate the observations Forbes made to our own microcosm, Lake Krankesjon in southern Sweden, that has been intensively studied by several research groups for more than three decades. Specifically, we focus on the question: Have we made any significant progress or did Forbes and colleagues blaze the trail through the unknown wilderness and we are mainly paving that intellectual road? We conclude that lakes are more isolated than many other biomes, but have, indeed, many extensions, for example, input from the catchment, fishing and fish migration. We also conclude that irrespective of whether lakes should be viewed as microcosms or not, the paper by Forbes has been exceptionally influential and still is, especially since it touches upon almost all aspects of the lake ecosystem, from individual behaviour to food web interactions and environmental issues. Therefore, there is no doubt that even if 125 years have passed, Forbes' paper still is a source of inspiration and deserves to be read. Hence, although aquatic ecology has made considerable progress over the latest century, Forbes might be viewed as one of the major pioneers and visionary scientists of limnology

Carbohydrate hydrogels with stabilized phage particles for bacterial biosensing: bacterium diffusion studies

Bacteriophage particles have been reported as potentially useful in the development of diagnosis tools for pathogenic bacteria as they specifically recognize and lyse bacterial isolates thus confirming the presence of viable cells. One of the most representative microorganisms associated with health care services is the bacterium Pseudomonas aeruginosa, which alone is responsible for nearly 15 % of all nosocomial infections. In this context, structural and functional stabilization of phage particles within biopolymeric hydrogels, aiming at producing cheap (chromogenic) bacterial biosensing devices, has been the goal of a previous research effort. For this, a detailed knowledge of the bacterial diffusion profile into the hydrogel core, where the phage particles lie, is of utmost importance. In the present research effort, the bacterial diffusion process into the biopolymeric hydrogel core was mathematically described and the theoretical simulations duly compared with experimental results, allowing determination of the effective diffusion coefficients of P. aeruginosa in the agar and calcium alginate hydrogels tested.Financial support to Victor M.
