    Treatment of comorbid chronic disease, such as depression, in people living with HIV/AIDS (PLWHA) increasingly falls to HIV treatment providers. Guidance in who will best respond to depression treatment and which patient-centered symptoms are best to target is limited

    Diurnal Immune Cell Migration Patterns Characterized in the Spaceflight Environment

    Daily diurnal immune rhythm shapes biological pathways of organisms and closely aligns with optimizing energy usage in response to environmental light-dark cycles. Immune mobilization depends on diurnal signals to regulate immunity. In spaceflight, disrupted circadian rhythms and immune systems are noted. However, crosstalk between these systems has not been fully characterized. To fill this knowledge gap, we utilized a ground-based model of spaceflight to phenotype diurnal immunity in mice. For this, 24-week-old male and female mice were exposed to a combination of single-housed, acute 15cGy 5-ion GCRsim irradiation and continuous hindlimb unloading for 2 weeks on a light:dark [12hr:12hr] cycle throughout. Blood was collected at 24 hours and 2 weeks post irradiation and flow cytometrically profiled. Additionally, ribo-depleted, bulk RNA sequencing characterized unique, diurnal and sex-specific biosignatures. This work expands our understanding of diurnal immunity which is important to consider for personalized medicine directives for astronauts.

    Educomunicação e diversidade: tecendo saberes

    Get PDF
    Com esta publicação Educomunicação e Diversidade: Tecendo Saberes, a Associação Brasileira de Pesquisadores e Profissionais de Educomunicação socializa uma importante contribuição para o aprofundamento e aprimorando de estudos e práticas educativas e comunicativas numa perspectiva de respeito às diversidades. A publicação está estruturada em quatro partes, a saber: I. Educomunicação e Políticas para a Cidadania; II. Práxis Educomunicativa: o principio da indissociabilidade entre ensino-pesquisa-extensão; III. Educomunicação e Formação em EAD; IV – Mediação Tecnológica. Trata-se, assim, de um trabalho coletivo que contém 19 capítulos onde contribuem 35 autores e coautores. Eis uma publicação que se destina não somente aos educomunicadores, mas a todos os que assumem o desafio de pensar numa outra forma possível de educar e de comunicar, mais colaborativa, intercultural, criativa e emancipatória, menos colonizadora e arrogante. Desejamos à leitora-interlocutora, ou ao leitor-interlocutor, uma leitura prazerosa, crítica e problematizadora dessa publicação que se  apresenta como um ensaio, mas com a pretensão e o potencial de contribuir para o avanço dos estudos em torno do campo de interface entre Comunicação e Educação, sempre com o imprescindível respeito às diversidades

    Escherichia coli as a model active colloid:A practical introduction

    Get PDF
    The flagellated bacterium Escherichia coli is increasingly used experimentally as a self-propelled swimmer. To obtain meaningful, quantitative results that are comparable between different laboratories, reproducible protocols are needed to control, `tune' and monitor the swimming behaviour of these motile cells. We critically review the knowledge needed to do so, explain methods for characterising the colloidal and motile properties of E.coli, cells, and propose a protocol for keeping them swimming at constant speed at finite bulk concentrations. In the process of establishing this protocol, we use motility as a high-throughput probe of aspects of cellular physiology via the coupling between swimming speed and the proton motive force.Comment: 18 pages, 16 figures, 4 table

    An update on novel non-invasive approaches for periodontal diagnosis

    No full text
    For decades there has been an ongoing search for clinically acceptable methods for the accurate, non-invasive diagnosis and prognosis of periodontitis. There are several well-known inherent drawbacks with current clinical procedures. The purpose of this review is to summarize some of the newly emerging diagnostic approaches, namely, infrared spectroscopy, optical coherence tomography (OCT), and ultrasound. The history and attractive features of these new approaches are briefly illustrated, and the interesting and significant inventions related to dental applications are discussed. The particularly attractive aspects for the dental community are that some of these methods are totally non-invasive, do not impose any discomforts to the patients during the procedure, and require no tissue to be extracted. For instance, multiple inflammatory indices withdrawn from near infrared spectra have the potential to identify early signs of inflammation leading to tissue breakdown. Morphologically, some other non-invasive imaging modalities, such as OCT and ultrasound, could be employed to accurately measure probing depths and assess the status of periodontal attachment, the front-line of disease progression. Given that these methods reflect a completely different assessment of periodontal inflammation, if clinically validated, these methods could either replace traditional clinical examinations for the diagnosis of periodontitis or at least serve as attractive complementary diagnostic tools. However, the potential of these techniques should be interpreted more cautiously given the multifactorial character of periodontal disease. In addition to these novel tools in the field of periodontal inflammatory diseases, other alternative modalities like microbiologic and genetic approaches are only briefly mentioned in this review because they have been thoroughly discussed in other comprehensive reviews.Peer reviewed: YesNRC publication: Ye

    Molecular mapping of periodontal tissues using infrared microspectroscopy

    <p>Abstract</p> <p>Background</p> <p>Chronic periodontitis is an inflammatory disease of the supporting structures of the teeth. Infrared microspectroscopy has the potential to simultaneously monitor multiple disease markers, including cellular infiltration and collagen catabolism, and hence differentiate diseased and healthy tissues. Therefore, our aim was to establish an infrared microspectroscopy methodology with which to analyze and interpret molecular maps defining pathogenic processes in periodontal tissues.</p> <p>Methods</p> <p>Specific key cellular and connective tissue components were identified by infrared microspectroscopy and using a chemical imaging method.</p> <p>Results</p> <p>Higher densities of DNA, total protein and lipid were revealed in epithelial tissue, compared to the lower percentage of these components in connective tissue. Collagen-specific tissue mapping by infrared microspectroscopy revealed much higher levels of collagen deposition in the connective tissues compared to that in the epithelium, as would be expected. Thus inflammatory events such as cellular infiltration and collagen deposition and catabolism can be identified by infrared microspectroscopy.</p> <p>Conclusion</p> <p>These results suggest that infrared microspectroscopy may represent a simple, reagent-free, multi-dimensional tool with which to examine periodontal disease etiology using entirely unprocessed tissue sections.</p
