Published: May 2017

The One of the most promising applications of hot water is aquaculture. Temperature is one of the most principle parameters affects aquaculture life. It can cause stress and mortality or superior environment for growth and reproduction. Shrimp is warm water aquaculture type need hot water supply. To increase pond production it is necessary to keep water temperature at 34oC. Artificial intelligence (AI) techniques are becoming useful as alternate approaches to conventional techniques or as components of integrated systems. They have been used to solve complicated practical problems in various areas and are becoming more and more popular nowadays. In this paper a control system using artificial neural network control (NNC) either adaptive fuzzy logic control (AFLC) are design to control the hot water temperature. A comparison study is applied between the performance of FLC and NNC. The performance of NNC is the best because the control design takes into consideration different variables which give an accurate output than FLC. Also this paper introduces a complete mathematical modeling and MATLAB SIMULINK model for the proposed aquaculture heating system.

Published: May 2017

A critical component of the dye sensitized solar cell (DSSC) is the nano-structured wide bandgap semiconductor (typically TiO2 ). The particle size, crystal structure, orientation, and scale of interconnected porosity are all critical to cell performance. In our lab, we have engineered and produced ceramic pastes including a hierarchy of nano- to micron-sized particles of varying morphologies and texture which yield novel, hybrid microstructures. We assert that while the nano-material provides the surface area, the micro particles provide conduits for easier diffusion of photo-generated electrons through the titania and also a pore structure for percolation of dye and electrolyte, giving enhanced photo-current and power output. The pastes also are of practical benefit, as they avoid shrinkage cracks during drying, and result in high quality thick films.

Published: May 2017

such as wind and solar plants presents an operational challenge for grid operators. The economic incentives and technical challenges that accompany large amounts of variable generation in island power systems are often much greater. The Hawaiian Electric Company and its subsidiaries, the Maui Electric Company and the Hawaii Electric Light Company have considerable experience in planning and operating power systems with relatively high levels of wind power. The islands of Hawaii and Maui operate power systems with high levels of wind power (more than 10% by energy) and have experienced and addressed challenges associated with the variability and uncertainty of wind power. The island of Maui is anticipating further wind plant deployments in the near future. Recent analyses of possible near-term deployment of large amounts of wind power on the Oahu power system (500MW of wind power; approximately 1200MW peak and 520MW minimum annual load) has shown the potential for this system to accept almost 25% of its energy from wind and solar power. This paper will identify some of the wind integration challenges and highlight the benefits of a variety of strategies that are expected to improve system economics and operational reliability, including proposed modifications to the baseload thermal fleet (deeper turndown, higher ramp rates, and tuned droop characteristics), advanced wind turbine grid support features, new operating strategies, wind forecasting and refinements to the up and down reserve requirements. This paper will present the key findings in the context of useful insights and lessons learned that are relevant to other island power systems considering very high levels of wind power.

Published: May 2017

The objectives of this work were to optimize the variables affecting pyrolysis and steam gasification of glycerol (by-product formed during biodiesel production); and to characterize the gaseous phase formed, in order to carry out its energetic use. The studied operation variables were reaction temperature (700-900 ºC), water flow rate (0-0.173 g·min-1), glycerol flow rate (0.009-0.676 g·min-1) and carrier gas (nitrogen) flow rate (30-180 cm3 ·min-1). The most interesting phase (analyzed by gas chromatography) was the gas fraction. In this work, gas fraction was composed by H2, CH4, CO, C2H6, C2H4 and CO2. The main gas generated was the hydrogen. Its generation was favoured by steam presence and its yield was increased in 224% in relation with pyrolysis process (default of water steam). The better conditions for studied process were 800 ºC, 0.074 g·min-1 of water flow rate, 0.009 g·min-1 of glycerol flow rate and 60 cm3 ·min-1 of nitrogen flow rate. In these conditions, the volume of synthesis gas was 1.86 L·(gglycerol) -1 and its higher heating value (HHV) was 26.70 MJ· (kgglycerol) -1. This study indicated that the bio-glycerol is an excellent raw material in the obtaining of medium heating value gases. These gases could be used as fuel in industrial furnaces or domestic use.

Authors: J. M. Encinar  , J. F. González  , G. Martínez  , N. Sánchez  , C. G. González
Published: May 2017

The objectives of this work were to optimize the variables affecting transesterification process for biodiesel production from castor oil, non edible oil, by acid catalysis (sulphuric and phosphoric acid) and basic catalysis (potassium methoxide and potassium hydroxide); and to characterize the biodiesel for its use as fuel in compression ignition motors. The studied operation variables were methanol/oil molar ratio (3:1, 6:1, 9:1, 12:1), temperature (25, 35, 45, 55, 65 ºC), and catalyst amount (2, 3, 4 wt.% in acid catalysis, and 0.5, 1.0, 1.5 wt.% in basic catalysis). Evolution of each process was followed by gas chromatography, determining the content of methyl esters at different reaction times. Biodiesel was characterized by a set of parameter according to European Standard, EN 14214. The best conditions for transesterification process were 9:1 methanol/oil molar ratio, 65 ºC, and the use of potassium methoxide as catalyst with concentration 1.0 wt.%. In these conditions, obtained biodiesel presents satisfactory values of water content, iodine and saponification values, flash and combustion points, and temperature of 50% of distillate. However, values of density, kinematic viscosity, cetane index and cold filter plugging point, that are heavily dependent on oil, move away from those required by the European Standard.

ULISES: AUTONOMOUS MOBILE ROBOT USING ULTRACAPACITORS-STORAGE ENERGY SYSTEM.
Authors: J.S. Artal  , R. Bandrés  , G. Fernández
Published: May 2017

Recent technology improvements enabled ultracapacitors (UCaps) to be an interesting option for short-term power applications, such as in industry, automotive and traction drives, regenerative energy system, telecommunication and medical equipment. UCaps are being developed as an alternative to pulse batteries. To be an attractive alternative, ultracapacitors must have at least one order of magnitude higher power and a much longer shelf and cycle life than batteries. UCaps have much lower energy density than batteries and their low energy density is, in most cases, the factor that determines the feasibility of their use in a particular power application. The main advantages of UCaps are that they can provide high power capability (60-120s is typical), excellent reversibility (90-95% or higher) and long cycle life (>105 cycles). Thus they exhibit 20-200times larger capacitance per unit volume or mass than conventional capacitors. In this paper, an autonomous mobile robot was converted from a conventional lead-acid or lithium-ion battery to an ultracapacitors as the power source. The integration of UCaps as element of energy storage on the robot was studied with the main of optimizing the energetic solution. The design of the ultracapacitors based power supply system is outlined.

Published: May 2017

The impact of microbial consortium comprising plant development advancing rhizobacteria (PGPR) like Rhizobium, Pseudomonas and Bacillus were tried independently and in blend of Arachis hypogaea. The mixes of previously mentioned PGPR strains essentially expanded photosynthetic color (chlorophyll an and b, add up to chlorophyll and carotenoid) and protein content in  A. hypogaea, when contrasted with the un-inoculated control. The consequences of this study propose that PGPR connected in mix can possibly build the photosynthetic colors and protein substance of A. hypogaea which can be a potential tool in increasing the yield in this economically important crop in sustainable way.
A exclusão na inclusão de crianças com transtorno do espectro autista em escola regular
Authors: Aguia Márcia Cristina Maciel de , Pondé Milena Pereira
Published: May 2017

Introdução: O transtorno do espectro autista (TEA) é classificado na 5ª edição do Manual Diagnóstico e Estatístico de Transtornos Mentais como um transtorno do neurodesenvolvimento. A definição biomédica do transtorno, contudo, não abarca o sentido sociocultural dessa condição. Objetivo: Este estudo analisa como se processa a inclusão escolar de crianças com diagnóstico de TEA a partir da perspectiva dos pais. Método: Estudo qualitativo de narrativa de histórias orais, eliciadas a partir de entrevistas semiestruturadas. Foram feitas 30 entrevistas com mães e pais de pessoas com diagnóstico prévio de TEA. As entrevistas foram gravadas, transcritas e categorizadas após análise de conteúdo. Resultados: A análise indica que a inclusão escolar de pessoas com TEA é permeada pelo sofrimento da criança, dos pais e dos profissionais da educação; além disso, a maioria dos pais entrevistados considerou que os profissionais da escola excluem os seus filhos. Conclusão: A inclusão de crianças com TEA em escolas regulares pode vir a ser mais um instrumento de exclusão e sofrimento para os envolvidos. O processo de inclusão escolar não pode se resumir a um procedimento normativo; deve envolver a forma como essas crianças são recebidas e tratadas na escola, assim como o preparo dos técnicos de educação para o processo de inclusão.

Anti psicóticos são uti lizados em diversos transtornos mentais, o que torna imperati vo o estudo de seus efeitos adversos, de maneira a amenizá-los e permiti r melhor adesão ao tratamento. Distúrbios do movimento são adversidades comuns, e sua abordagem, em geral, se baseia na redução da dose, troca do anti psicóti co e/ou introdução de uma medicação anti colinérgica. O objeti vo deste estudo é realizar uma revisão sistemáti ca sobre o uso de medicações anti colinérgicas na abordagem de sintomas extrapiramidais causados por anti psicóticos. Através desta revisão, será realizada uma análise crítica sobre esse uso. A busca bibliográfi ca foi realizada através das bases de pesquisa PubMed e SciELO. Foram incluídos 24 dos 318 arti gos encontrados. Os arti gos foram organizados nos seguintes temas: efeitos anti colinérgicos de anti psicóti cos; distúrbios do movimento; anti psicóticostípicos e atípicos; polifarmácia de anti psicóti cos; uso crônico e descontinuação de anti colinérgicos. O anti psicóti co em uso e a associação desses fármacos podem influenciar na prescrição de medicações anti colinérgicas e no aparecimento de sintomas extrapiramidais. Antes de iniciar o uso de uma medicação anti colinérgica, é importante que o clínico considere trocar o anti psicóti co em uso ou reduzir sua dose. A necessidade de uso de medicações anti colinérgicas deve ser revisada periodicamente e, quando possível, sua retirada deve ser realizada de forma gradual. O uso profi láti co desses fármacos é contraindicado, e o uso terapêutico deve ser evitado em idosos e em pacientes com discinesia tardia.

Published: May 2017

Study Design

Prospective cohort study.

Background

Patient-reported outcome measurements (PROMs) are widely used to evaluate functional limitations. Considering PROMs for shoulder instability, information is lacking with regard to what constitutes a relevant change from baseline scores.

Objectives

To evaluate the responsiveness of the Western Ontario Shoulder Instability Index (WOSI) and the Oxford Shoulder Instability Score (OSIS) and estimate their minimal important change (MIC).

Methods

One hundred five consecutive patients with shoulder instability completed 5 PROMs at baseline and at 6-month follow-up. The PROMs included the WOSI and OSIS, the Simple Shoulder Test, the Oxford Shoulder Score, and the Disabilities of the Arm, Shoulder and Hand assessment. Patients also rated their functional change on an anchor question at follow-up. Responsiveness was evaluated by testing 9 hypotheses regarding predefined correlations between the changes in PROM scores, by calculating the area under the receiver operating characteristic curve and by calculating the standardized response mean and effect size statistics. The MIC was determined by identifying the optimal cutoff on the receiver operating characteristic curve.

Results

Seven out of 9 hypotheses (78%) were confirmed; as expected, a high correlation (0.77) was found between change scores of the WOSI and OSIS, whereas the correlations of the change scores of the WOSI and OSIS with those of general shoulder PROMs were slightly lower (0.61–0.75). The area under the curve was 0.83 (95% confidence interval: 0.75, 0.91) for the OSIS and 0.82 (95% confidence interval: 0.74, 0.90) for the WOSI. The MIC was about 6 points for the OSIS and about 14 points for the WOSI.

Conclusion

Both the WOSI and OSIS are able to measure change in shoulder function in patients with shoulder instability. The estimated MIC is 6 points for the OSIS (on a scale from 0 to 48) and 14 points for the WOSI (on a scale from 0 to 100). J Orthop Sports Phys Ther 2017;47(6):402–410. doi:10.2519/jospt.2017.6548
Knee Loading Deficits During Dynamic Tasks in Individuals Following Anterior Cruciate Ligament Reconstruction
Authors: Pratt Kristamarie A. , Sigward Susan M.
Published: May 2017

Study Design

Controlled laboratory study, cross-sectional.

Background

Well-documented deficits in sagittal plane knee loading during dynamic tasks indicate that individuals limit the magnitude of knee loading following anterior cruciate ligament reconstruction (ACLR). It is unknown how these individuals modulate the speed of knee flexion during loading, which is particularly important as they progress to running during rehabilitation.

Objective

To investigate how individuals following ACLR perform dynamic knee loading tasks compared to healthy controls.

Methods

Two groups of recreationally active individuals participated: 15 healthy controls and 15 individuals post-ACLR (ACLR group). Participants performed 3 trials of overground running and a single-limb loading (SLL) task. Sagittal plane range of motion, peak knee extensor moment, peak knee flexion angular velocity, peak knee power absorption, and rate of knee extensor moment were calculated during deceleration. A mixed-factor multivariate analysis of variance was performed to compare differences in variables between groups (ACLR and control), limbs (within ACLR), and tasks (within control).

Results

Knee power absorption, knee flexion angular velocity, and rate of knee extensor moment were lower in reconstructed limbs (for the SLL task: 5.6 W/kg, 325.8°/s, and 10.5 Nm/kg/s, respectively; for running: 11.8 W/kg, 421.4°/s, and 38.2 Nm/kg/s, respectively) compared to nonsurgical limbs (for the SLL task: 9.7 W/kg, 432.0°/s, and 19.1 Nm/kg/s, respectively; for running: 18.8 W/kg, 494.1°/s, and 72.8 Nm/kg/s, respectively) during both tasks (P<.001). The magnitudes of between-limb differences in knee flexion angular velocity were similar in both tasks.

Conclusion

Despite lower loading demands during SLL, individuals post-ACLR exhibit deficits in knee dynamics during SLL and running, suggesting an inability or reluctance to dynamically accommodate forces at the knee when progressing to running in rehabilitation.

Published: May 2017

Study Design

A prospective cohort study.

Background

Motor control dysfunctions have been commonly reported in patients with chronic nonspecific low back pain (LBP). Physical therapists need clinical tools with adequate psychometric properties to assess such patients in clinical practice. The deep muscle contraction (DMC) scale is a clinical rating scale for assessing patients' ability to voluntarily contract deep abdominal muscles.

Objectives

To investigate the intrarater reliability, floor and ceiling effects, internal and external responsiveness, and correlation analysis (with ultrasound measures) of the DMC scale in patients with chronic nonspecific LBP undergoing a lumbar stabilization exercise program.

Methods

Sixty-two patients with chronic nonspecific LBP were included. At baseline, self-report questionnaires were administered to patients and a trained assessor evaluated abdominal muscle recruitment with the DMC scale and ultrasound imaging. Four ratios of the change in abdominal muscle thickness between the resting and contracted states were calculated through the ultrasound measures. After 1 week, the same ultrasound measures and DMC scale were collected again for the reliability analysis. The proportions of patients with the lowest and highest scores on the DMC scale were calculated to investigate floor and ceiling effects. All patients underwent a lumbar stabilization program, administered twice a week for 8 weeks. After the treatment period, all measures were collected again, with the addition of the global perceived effect scale, to assess the internal and external responsiveness of the measures. Correlation coefficients between ultrasound ratios and DMC scale total and subscale scores were also calculated.

Results

The intrarater reliability of the DMC scale and the 4 ratios of abdominal muscle thickness varied from moderate to excellent. The DMC scale showed no floor or ceiling effects. Results for internal responsiveness of the DMC scale showed large effect sizes (2.26; 84% confidence interval [CI]: 2.06, 2.45), whereas the external responsiveness was below the proposed threshold (area under the curve = 0.54; 95% CI: 0.39, 0.68). Fair and significant correlations between some ultrasound ratios and DMC subscales were found.

Conclusion

The DMC scale was demonstrated to be a reliable tool, with no ceiling and floor effects, and to detect change in the ability to contract the deep abdominal muscles after a lumbar stabilization exercise program, but with low accuracy for estimating patient-perceived clinical outcome.

Published: May 2017

The Brazilian elderly population, that is, the population aged 60 or older according to the Elderly Estatute, has increased in recent decades, a phenomenon observed in Brazil and worldwide. This rapid growth represents a major political and social impact, reflecting the consequent rise in cost of health services because this is the population that most need this service.

Objective: To understand the meaning of Nursing Consultation for elderly women assisted at a School Clinic in Mountain Region-RJ-Brazil.

Method: The is a qualitative study of descriptive and exploratory nature supported by the theoretical and methodological framework of Alfred Schutz through sociological phenomenology. The study was approved by the Ethics and Research Committee of the Arthur Sá Earp Neto Faculty on April 11, 2015 under Opinion number 1.019361. We used phenomenological interview.

Results: We performed 19 interviews with elderly women aged 60-80 years. The responses provided the understanding of women's experiences during the nursing consultation. This study gave rise to three categories that revealed the intentionality of this social group when searching for the nursing consultation: "To be well assisted", "To have resolving power" and "To prevent health problems".

Conclusions: The found that the nursing consultation promotes the approximation between women and the nursing professionals, establishing bonds, presenting efficient and effective results to treatment and prevention, besides providing mutual learning.

Authors: Oliveira Cristiano Claudino , De Faveri Julio , Domingues Maria Aparecida Custódio
Published: May 2017

Background: Association of extragonadal germ cell tumors EGCT with haematological malignancies is rare with a very limited prognosis.

Methods and findings: We report a case of a man, 21 years old, with progressive dyspnea, chest pain, night sweats, generalized edema, hemoptysis, pancytopenia and increased serum levels of alpha-fetoprotein (AFP), beta-fraction of the hormone chorionic gonodotrophin (beta-HCG) and lactic dehydrogenase. Chest computed tomography described a mediastinum mass measuring 11.3 x 7.3 cm whose biopsy revealed malignant germ cell neoplasia expressing positivity for cytokeratin, CD30 and AFP, indicating an embryonal carcinoma with teratoma. Bone marrow biopsy revealed interstitial infiltration by malignant neoplastic cells positive for CD68, CD163 and lysozyme, allowing the diagnosis of histiocytic sarcoma. The patient had a poor evolution, with death, sixteen days after admission.

Conclusion: Histiocytic proliferations are very rare and rapidly fatal. Etiopathogenic theories for the simultaneity of these malignancies have been described based on processes of transformation from a same cellular precursor.

INTRODUCTION: Chronic-degenerative diseases need specialized health care, especially in palliative care, since from the beginning of the disease the elderly is in this classification. In this context, the study aimed to know the meaning of palliative care to the elderly person from the nurse
METHODS: This is a descriptive, cross-sectional, qualitative study carried out in a private tertiary hospital in the Northeast of Brazil. The survey was conducted from March to June 2016, with 19 nurses. In the data collection, a semi-structured interview, with four questions were used: what does palliative care mean to you? What does care for the elderly in hospice care mean to you? What strategies do you adopt to promote palliative care for the elderly? Tell me about your experience in providing palliative care to the elderly. The technique of data analysis and organization was the Discourse of the Collective Subject.
RESULTS: Four categories of palliative care were produced: meaning palliative care; Experience in providing palliative care to the elderly; Meaning of caring for the elderly in palliative care; Strategies to promote palliative care for the elderly.
CONCLUSION: The meaning of palliative care was synonymous with comfort and quality of life. It is important to emphasize the patient-centered care and to carry out further studies on the subject to make nursing professionals aware of the importance of promoting adequate behavior in palliative care.

Published: May 2017

Introduction: Patients with visual impairment present greater difficulty in achieving adequate oral hygiene due to restricted eyesight. Therefore, oral hygiene motivation and instruction methods should be adapted to these patients to understand the importance of bacterial plaque control, both for the health of dental tissues and periodontal tissues

Objective: The objective of the present study was to compare the plaque index (PI) of patients with and without visual impairment before and after the institution of oral hygiene instructions through a Randomized Clinical Trial. Twenty patients with visual impairment (Group 1) from the Instituto dos Cegos and 20 without visual impairment (Group 2) from the ASCES Periodontia Clinic were selected. Data were collected through the IP of O'Leary and reevaluated every 21 days for four sessions.

Results: in both groups, the mean of PI decreased with the time of evaluation, with a significant difference between the evaluations (p <0.001). Group 1 had a mean PI higher than group 2 only in the fourth evaluation, but there was no significant difference (p> 0.05). As for the mean of the PI assessments, group 2 presented a mean higher than group 1, but without significant difference (p> 0.05).

Conclusion: The study therefore suggests that there is no difference in PI in patients with or without visual impairment, and that the guidelines stimulate and motivate an improvement in oral hygiene conditions.
Les Lyonnais et saint Bonaventure (fin du XV e -XVIII e siècles)
Authors: Henryot Fabienne
Published: May 2017

C’est au couvent des cordeliers de Lyon que Bonaventure est mort en 1274. Deux siècles plus tard, à la suite de sa canonisation prononcée en 1482, sa dépouille est convoquée dans une série de discours et de pratiques autant politiques que religieux, visant à légitimer des pouvoirs superposés. Le pouvoir royal d’abord, au tournant des xv e  et xvi e  siècles, s’empare de la relique pour s’imposer à Lyon. Puis ce sont les institutions municipales qui l’instrumentalisent pour créer et rendre visible un ordre civique et moral harmonieux et cohérent, particulièrement au xvii e  siècle. Enfin, les franciscains lyonnais tentent de récupérer la relique pour consolider leur unité mise à mal par un siècle de dissensions internes. La relique de saint Bonaventure est ainsi un exemple manifeste de l’usage politique et social des reliques dans la France urbaine moderne, favorisant l’union, la réconciliation et la territorialisation de l’espace urbain.

In rheumatoid arthritis (RA), cartilage and bone matrix are degraded, and extracellular matrix (ECM) proteins, acting as cellular activators, are liberated. Similar to ECM proteins, matrix-bound chemokines, cytokines, and growth factors (GFs) influence functional properties of key cells in RA, especially synovial fibroblasts. The role of these molecules on attachment, migration, and proinflammatory and prodestructive activation of RASFs was analyzed. Adhesion/migration of RASFs were examined under GF-enriched (GF+) or –reduced (GF−) conditions with or without addition of matrix-associated GFs, TGF-β, and platelet-derived GF to GF− or culture supernatants. Fibroblast adhesion and alterations in proinflammatory/prodestructive properties (e.g., IL-6/matrix metalloproteinase 3-release) in response to matrix-associated molecules were compared. Effects of GF+, GF−, and other ECM components on human RASF-mediated cartilage invasion were examined in the SCID mouse model. RASF adhesion under GF− conditions was significantly lower compared with GF+ conditions (6.8- versus 8.3-fold). This effect was specific for RA because control cells showed opposite effects (e.g., osteoarthritis synovial fibroblasts [SF]; GF− versus GF+: 10.7- versus 8-fold). Addition of TGF-β to GF− increased RASF attachment (12.7-fold) compared with other matrices and components. RASF adhesion to GF+ matrix resulted in the strongest IL-6 and matrix metalloproteinase-3 release, and was even more pronounced compared with supplementation of single GFs. In vivo, GF− matrix decreased RASF-mediated cartilage invasion compared with GF+ matrix. ECM components and especially GFs when bound within ECM actively enhance RASF attraction and cartilage adhesion. This observation was specific for RASFs as a reverse behavior was observed for controls.

Obesity is associated with increased risk for infections and poor responses to vaccinations, which may be due to compromised B cell function. However, there is limited information about the influence of obesity on B cell function and underlying factors that modulate B cell responses. Therefore, we studied B cell cytokine secretion and/or Ab production across obesity models. In obese humans, B cell IL-6 secretion was lowered and IgM levels were elevated upon ex vivo anti-BCR/TLR9 stimulation. In murine obesity induced by a high fat diet, ex vivo IgM and IgG were elevated with unstimulated B cells. Furthermore, the high fat diet lowered bone marrow B cell frequency accompanied by diminished transcripts of early lymphoid commitment markers. Murine B cell responses were subsequently investigated upon influenza A/Puerto Rico/8/34 infection using a Western diet model in the absence or presence of docosahexaenoic acid (DHA). DHA, an essential fatty acid with immunomodulatory properties, was tested because its plasma levels are lowered in obesity. Relative to controls, mice consuming the Western diet had diminished Ab titers whereas the Western diet plus DHA improved titers. Mechanistically, DHA did not directly target B cells to elevate Ab levels. Instead, DHA increased the concentration of the downstream specialized proresolving lipid mediators (SPMs) 14-hydroxydocosahexaenoic acid, 17-hydroxydocosahexaenoic acid, and protectin DX. All three SPMs were found to be effective in elevating murine Ab levels upon influenza infection. Collectively, the results demonstrate that B cell responses are impaired across human and mouse obesity models and show that essential fatty acid status is a factor influencing humoral immunity, potentially through an SPM-mediated mechanism.

Studies in various animal models suggest an important role for pulmonary macrophages in the pathogenesis of pulmonary hypertension (PH). Yet, the molecular mechanisms characterizing the functional macrophage phenotype relative to time and pulmonary localization and compartmentalization remain largely unknown. In this study, we used a hypoxic murine model of PH in combination with FACS to quantify and isolate lung macrophages from two compartments over time and characterize their programing via RNA sequencing approaches. In response to hypoxia, we found an early increase in macrophage number that was restricted to the interstitial/perivascular compartment, without recruitment of macrophages to the alveolar compartment or changes in the number of resident alveolar macrophages. Principal component analysis demonstrated significant differences in overall gene expression between alveolar and interstitial macrophages (IMs) at baseline and after 4 and 14 d hypoxic exposure. Alveolar macrophages at both day 4 and 14 and IMs at day 4 shared a conserved hypoxia program characterized by mitochondrial dysfunction, proinflammatory gene activation, and mTORC1 signaling, whereas IMs at day 14 demonstrated a unique anti-inflammatory/proreparative programming state. We conclude that the pathogenesis of vascular remodeling in hypoxic PH involves an early compartment-independent activation of lung macrophages toward a conserved hypoxia program, with the development of compartment-specific programs later in the course of the disease. Thus, harnessing time- and compartment-specific differences in lung macrophage polarization needs to be considered in the therapeutic targeting of macrophages in hypoxic PH and potentially other inflammatory lung diseases.
FcγRIIIa Signaling Modulates Endosomal TLR Responses in Human CD4+ T Cells

Recognition of Ab-opsonized pathogens by immune cells triggers both TLR and Fc receptor signaling. Fc receptors endocytose modified nucleic acids bound to Abs and deliver them to endosomes, where they are recognized by nucleic acid–sensing TLRs (NA-TLRs). We show that in CD4+ T cells, NA-TLRs, TLR3, TLR8, and TLR9 are upregulated by FcγRIIIa-pSyk cosignaling and localize with FcγRIIIa on the cell surface. TLR9 accumulates on the cell surface, where it recognizes CpG oligonucleotide 2006. Subcellular location of NA-TLRs is a key determinant in discriminating self versus viral nucleic acid. Hydroxychloroquine used for treating systemic lupus erythematosus and a Syk inhibitor blocked NA-TLR localization with FcγRIIIa. Engaging TLR9 with CpG oligonucleotide contributes to the development of IL17A+ and IL-21+ populations. RNA-sequencing analysis showed upregulation of proinflammatory cytokines, NF-κB signaling, and heat shock protein pathway RNA transcripts. These data suggest a role for FcγRIIIa-pSyk cosignaling in modulating NA-TLR responses in human CD4+ T cells by affecting the amounts and cellular distribution. These events are important for understanding of autoimmune pathology.

Macrophage accumulation is a critical step during development of chronic inflammation, initiating progression of many devastating diseases. Leukocyte-specific integrin αDβ2 (CD11d/CD18) is dramatically upregulated on macrophages at inflammatory sites. Previously we found that CD11d overexpression on cell surfaces inhibits in vitro cell migration due to excessive adhesion. In this study, we have investigated how inflammation-mediated CD11d upregulation contributes to macrophage retention at inflammatory sites during atherogenesis. Atherosclerosis was evaluated in CD11d−/−/ApoE−/− mice after 16 wk on a Western diet. CD11d deficiency led to a marked reduction in lipid deposition in aortas and isolated macrophages. Macrophage numbers in aortic sinuses of CD11d−/− mice were reduced without affecting their apoptosis and proliferation. Adoptive transfer of fluorescently labeled wild-type and CD11d−/− monocytes into ApoE−/− mice demonstrated similar recruitment from circulation, but reduced accumulation of CD11d−/− macrophages within the aortas. Furthermore, CD11d expression was significantly upregulated on macrophages in atherosclerotic lesions and M1 macrophages in vitro. Interestingly, expression of the related ligand-sharing integrin CD11b was not altered. This difference defines their distinct roles in the regulation of macrophage migration. CD11d-deficient M1 macrophages demonstrated improved migration in a three-dimensional fibrin matrix and during resolution of peritoneal inflammation, whereas migration of CD11b−/− M1 macrophages was not affected. These results prove the contribution of high densities of CD11d to macrophage arrest during atherogenesis. Because high expression of CD11d was detected in several inflammation-dependent diseases, we suggest that CD11d/CD18 upregulation on proinflammatory macrophages may represent a common mechanism for macrophage retention at inflammatory sites, thereby promoting chronic inflammation and disease development.
Assessment of Oral and Dental Health Status in Children with Cerebral Palsy: An Exploratory Study
Authors: Sedky Nabila Ahmed
Published: May 2017

Objectives

Evaluating oral and dental health status in Egyptian children with cerebral palsy (CP) in relation to gross motor skills and types of CP.

Materials and methods

Cross-sectional study was conducted at el-Shatby Hospital for Children, Alexandria, Egypt. Oral examination for 62 children with CP between the age range 3 and 12 years was performed, and decayed, missing, and filled permanent teeth (DMFT)/decayed and filled primary teeth (dft), simplified oral hygiene index (OHI-S), and modified gingival index (MGI) were charted. Maxillofacial defects, dental problems, and drooling of saliva were assessed. Children's CP type, motor milestone, and gross motor skills were determined. All statistical analyses were carried out at p<0.05 and 0.01.

Results

About 84.0% of children had spastic quadriplegia, 41.9% were sit-supported, 32.3% had level IV Gross Motor Function Classification System (GMFCS), 29.0% had level V no maxillofacial defects, 14.5% had dentin exposure greater than one-third of the surface, and 22.6% had frequent/severe drooling saliva. Caries prevalence comprised 54.8%, 53.2% had poor oral hygiene (OHI-S), and 43.6% had severe gingival inflammation (MGI). The first best predictor variable for dft was “motor milestone” The GMFCS (levels IV and V) was the first best predictor variable for DMFT, OHI-S, and MGI.

Conclusion

The majority of children had dental caries, poor oral hygiene, and severe gingival inflammation. Children who were sit-supported, had no neck support, and stand-supported were suffering from dental caries (dft) more than children who were sitting and walking alone. Children with levels IV/V GMFCS were prone to have dental caries (DMFT), susceptible to suffer from bad oral hygiene, and older children experiencing severe gingivitis more than younger ones.
