The chemokine receptor CX3CR1 is directly involved in the arrest of breast cancer cells to the skeleton
Creators: name: Fong, Alan M
Publisher: name: BioMed Central Ltd
Year: 2011

description: Abstract Introduction Skeletal metastases from breast adenocarcinoma are responsible for most of the morbidity and mortality associated with this tumor and represent a significant and unmet need for therapy. The arrival of circulating cancer cells to the skeleton depends first on the adhesive interactions with the endothelial cells lining the bone marrow sinusoids, and then the extravasation toward chemoattractant molecules produced by the surrounding bone stroma. We have previously shown that the membrane-bound and cell-adhesive form of the chemokine fractalkine is exposed on the luminal side of human bone marrow endothelial cells and that bone stromal cells release the soluble and chemoattractant form of this chemokine. The goal of this study was to determine the role of fractalkine and its specific receptor CX3CR1 in the homing of circulating breast cancer cells to the skeleton. Methods We employed a powerful pre-clinical animal model of hematogenous metastasis, in which fluorescent cancer cells are identified immediately after their arrival to the bone. We engineered cells to over-express either wild-type or functional mutants of CX3CR1 as well as employed transgenic mice knockout for fractalkine. Results CX3CR1 protein is detected in human tissue microarrays of normal and malignant mammary glands. We also found that breast cancer cells expressing high levels of this receptor have a higher propensity to spread to the skeleton. Furthermore, studies with fractalkine-null transgenic mice indicate that the ablation of the adhesive and chemotactic ligand of CX3CR1 dramatically impairs the skeletal dissemination of circulating cancer cells. Finally, we conclusively confirmed the crucial role of CX3CR1 on breast cancer cells for both adhesion to bone marrow endothelium and extravasation into the bone stroma. Conclusions We provide compelling evidence that the functional interactions between fractalkine produced by both the endothelial and stromal cells of bone marrow and the CX3CR1 receptor on breast cancer cells are determinant in the arrest and initial lodging needed for skeletal dissemination.

description: We investigate the performance of quantum teleportation under a lossy environment using two different types of optical hybrid qubits. One is the hybrid of the vacuum and single-photon states with coherent states and the other is the hybrid of polarized single-photon states with coherent states. We have shown that the hybrid qubit using vacuum and single-photon states is generally more robust to photon loss effects compared to the one using the photon polarization with respect to fidelities and success probabilities of quantum teleportation.

description: It is shown that the spin polarized condensate appears in quark matter at high baryon density and low temperature due to the tensor-type four-point interaction in the Nambu-Jona-Lasinio-type model as a low energy effective theory of quantum chromodynamics. It is indicated within this low energy effective model that the chiral symmetry is broken again by the spin polarized condensate as increasing the quark number density, while the chiral symmetry restoration occurs in which the chiral condensate disappears at a certain density.

description: Evaluation of single, coincidence and anticoincidence gamma-ray spectrometry methods has been carried out with the aim to search for double-electron capture in 74Se. This process is unique, because there is probability for transition to the 2+ excited state in 74Ge (1204 keV), and de-excitation through two gamma-quanta cascade with energies of 595.9 keV and 608.4 keV. Long-term measurements with anticosmic shielded HPGe spectrometer and the coincidence HPGe-NaI(Tl) spectrometer did not show any evidence for the double-electron capture in 74Se. The best limit for the half-life of the double electron capture in 74Se (both for the neutrinoless and two neutrino processes) was estimated to be >1.5x10E19 years.

Publisher: name: BioMed Central Ltd
Year: 2005

description: Abstract: Background: The respiratory tract epithelium is a critical environmental interface that regulates inflammation. In chronic infectious airway diseases, pathogens may permanently colonize normally sterile luminal environments. Host-pathogen interactions determine the intensity of inflammation and thus, rates of tissue injury. Although many cells become refractory to stimulation by pathogen products, it is unknown whether the airway epithelium becomes either tolerant or hypersensitive in the setting of chronic infection. Our goals were to characterize the response of welldifferentiated primary human tracheobronchial epithelial cells to Pseudomonas aeruginosa, to understand whether repeated exposure induced tolerance and, if so, to explore the mechanism(s). Methods: The apical surface of well-differentiated primary human tracheobronchial epithelial cell cultures was repetitively challenged with Pseudomonas aeruginosa culture filtrates or the bacterial media control. Toxicity, cytokine production, signal transduction events and specific effects of dominant negative forms of signaling molecules were examined. Additional experiments included using IL-1β and TNFα as challenge agents, and performing comparative studies with a novel airway epithelial cell line. Results: An initial challenge of the apical surface of polarized human airway epithelial cells with Pseudomonas aeruginosa culture filtrates induced phosphorylation of IRAK1, JNK, p38, and ERK, caused degradation of IκBα, generation of NF-κB and AP-1 transcription factor activity, and resulted in IL-8 secretion, consistent with activation of the Toll-like receptor signal transduction pathway. These responses were strongly attenuated following a second Pseudomonas aeruginosa, or IL-1β, but not TNFα, challenge. Tolerance was associated with decreased IRAK1 protein content and kinase activity and dominant negative IRAK1 inhibited Pseudomonas aeruginosa -stimulated NF- κB transcriptional activity. Conclusion: The airway epithelial cell response to Pseudomonas aeruginosa entails adaptation and tolerance likely mediated, in part, by down-regulation of IRAK1.
Head-on collisions of dense granular jets

description: When a dense stream of dry, non-cohesive grains hits a fixed target, a collimated sheet is ejected from the impact region, very similar to what happens for a stream of water. In this study, as a continuation of the investigation why such remarkably different incident fluids produce such similar ejecta, we use discrete particle simulations to collide two unequal-width granular jets head-on in two dimensions. In addition to the familiar coherent ejecta, we observe that the impact produces a far less familiar quasi-steady-state corresponding to a uniformly translating free surface and flow field. Upon repeating such impacts with multiple continuum fluid simulations, we show that this translational speed is controlled only by the total energy dissipation rate to the power $1.5$, and is independent of the details of the jet composition. Our findings, together with those from impacts against fixed targets, challenge the principle of scattering in which material composition is inferred from observing the ejecta produced during impact.

description: Abstract Background The purpose of this study is to explore the relationship between function, pain and stiffness outcomes with individual and community socioeconomic status (SES) measures among individuals with radiographic knee osteoarthritis (rOA). Methods Cross-sectional data from the Johnston County Osteoarthritis Project were analyzed for adults age 45 and older with knee rOA (n = 782) and a subset with both radiographic and symptomatic knee OA (n = 471). Function, pain and stiffness were measured using the Western Ontario and McMasters Universities Index of Osteoarthritis (WOMAC). Individual SES measures included educational attainment (<12 years, ≥12 years) and occupation type (managerial, non-managerial), while community SES was measured using Census block group poverty rate (<12%, 12-25%, ≥25%). SES measures were individually and simultaneously examined in linear regression models adjusting for age, gender, race, body mass index (BMI), occupational physical activity score (PAS), comorbidity count, and presence of hip symptoms. Results In analyses among all individuals with rOA, models which included individual SES measures were observed to show that occupation was significantly associated with WOMAC Function (β =2.91, 95% Confidence Interval (CI) = 0.68-5.14), WOMAC Pain (β =0.93, 95% CI = 0.26-1.59) and WOMAC Total scores (β =4.05, 95% CI = 1.04-7.05), and education was significantly associated with WOMAC Function (β =3.57, 95% CI = 1.25-5.90) and WOMAC Total (β =4.56, 95% CI = 1.41-7.70) scores. In multivariable models including all SES measures simultaneously, most associations were attenuated. However, statistically significant results for education remained between WOMAC Function (β =2.83, 95% CI = 0.38-5.28) and WOMAC Total (β =3.48, 95% CI = 0.18-6.78), as well as for the association between occupation and WOMAC Pain (β =0.78, 95% CI = 0.08-1.48). In rOA subgroup analyses restricted to those with symptoms, we observed a significant increase in WOMAC Pain (β =1.36, 95% CI = 0.07-2.66) among individuals living in a block group with poverty rates greater than 25%, an association that remained when all SES measures were considered simultaneously (β =1.35, 95% CI = 0.06-2.64). Conclusions Lower individual and community SES are both associated with worse function and pain among adults with knee rOA.

description: Abstract Background Physicians report willingness to provide preventive dental care, but optimal methods for their training and support in such procedures are not known. This study aimed to evaluate the effect of three forms of continuing medical education (CME) on provision of preventive dental services to Medicaid-enrolled children by medical personnel in primary care physician offices. Methods Practice-based, randomized controlled trial. Setting: 1,400 pediatric and family physician practices in North Carolina providing care to an estimated 240,000 Medicaid-eligible children aged 0–3 years. Interventions: Group A practices (n = 39) received didactic training and course materials in oral health screening, referral, counseling and application of fluoride varnish. Group B practices (n = 41) received the same as Group A and were offered weekly conference calls providing advice and support. Group C practices (n = 41) received the same as Group B and were offered in-office visit providing hands-on advice and support. In all groups, physicians were reimbursed $38–$43 per preventive dental visit. Outcome measures were computed from reimbursement claims submitted to NC Division of Medical Assistance. Primary outcome measure: rate of preventive dental services provision per 100 well-child visits. Secondary outcome measure: % of practices providing 20 or more preventive dental visits. Results 121 practices were randomized, and 107 provided data for analysis. Only one half of Group B and C practices took part in conference calls or in-office visits. Using intention-to-treat analysis, rates of preventive dental visits did not differ significantly among CME groups: GroupA = 9.4, GroupB = 12.9 and GroupC = 8.5 (P = 0.32). Twenty or more preventive dental visits were provided by 38–49% of practices in the three study groups (P = 0.64). Conclusion A relatively high proportion of medical practices appear capable of adopting these preventive dental services within a one year period regardless of the methods used to train primary health care providers.

description: A new method for diagnosing the temporal characteristics of ultrashort electron bunches with linear energy chirp generated from a laser wakefield accelerator is described. When the ionization-injected bunch interacts with the back of the drive laser, it is deflected and stretched along the direction of the electric field of the laser. Upon exiting the plasma, if the bunch goes through a narrow slit in front of the dipole magnet that disperses the electrons in the plane of the laser polarization, it can form a series of bunchlets that have different energies but are separated by half a laser wavelength. Since only the electrons that are undeflected by the laser go through the slit, the energy spectrum of the bunch is modulated. By analyzing the modulated energy spectrum, the shots where the bunch has a linear energy chirp can be recognized. Consequently, the energy chirp and beam current profile of those bunches can be reconstructed. This method is demonstrated through particle-in-cell simulations and experiment.

description: G22.0+0.0 and G23.5+0.1 are diffuse hard X-ray sources discovered in the ASCA Galactic Plane Survey. We present Suzaku results of spectral analysis for these sources. G22.0+0.0 is confirmed to be a largely extended emission. The spectra were represented by a highly absorbed power-law model with a photon index of 1.7+/-0.3 and a moderately absorbed thermal emission with a temperature of 0.34^{+0.11}_{-0.08} keV. The difference in the N_{H} values between the two components suggests that the thermal component is unrelated with the power-law component and is a foreground emission located in the same line-of-sight. G23.5+0.1 is an extended source with a size of 3'.5. The spectra were fitted with an absorbed power-law model with a photon index of 2.4^{+0.5}_{-0.4}. The spatial and spectral properties show that both are candidates of old pulsar wind nebulae (PWNe). In addition to the extended sources, we analyzed spectra of three point sources found in the observed fields. Based on the spectral features, we discuss origin of the sources.

description: In this paper an analytical and a semi-analytical technique to compute low thrust Collision Avoidance Manoeuvres (CAMs) are presented and tested against a large dataset of Conjunction Data Messages (CDMs). Such CDMs simulate real conjunctions and they are derived from a screening against a background Two-Line Element population in different orbit scenarios: early Geostationary transfer and insertion into GEO, GEO graveyard, Low Earth Orbit (LEO) to high-LEO transfer, and typical station keeping activities in LEO and GEO. A standard and an improved operational concept are simulated to manage the large uncertainty associated to the long-thrusting arcs present in the different orbit scenarios considered. On all these cases, the Close Approach (CA) is first analysed, in terms of miss distance, relative velocity and position on the b-plane, and the probability of collision at time of close approach. Then, the focus shifts to how CAM influences the displacement in the b-plane, expense for the manoeuvre and efficacy of it. For each of them, different Accepted Collision Probability Level (ACPL) thresholds and conjunction notification times are tested for CAM design. We analyse the convergence of the proposed methods and the capabilities to achieve the required ACPL for a given operational scenano.

One of the purposes of the test campaign was also the assessment of the diagnostic equipment suitably designed for this activity in view of its future integration inside a vacuum chamber for testing in relevant environment. The thrust balance, capable of hosting in its cradle an entire 3U CubeSat, proved to effectively measure the low level of thrust produced by the propulsion system (i.e. 500 mN in vacuum nominal condition) thus allowing the experimental measurement of the specific impulse together with the output of the flowmeter also integrated in the moving equipment of the thrust balance. The propulsion system has been operated in pulse and continuous mode matching most of its critical requirements.
Famiglie vulnerabili: un’esperienza di «educativa domiciliare»

Publisher: name: Rivista Italiana di Educazione Familiare
Year: 2014

description: This article reports the results of a participative research-training-intervention project that involved 12 educators and 18 vulnerable families over an intervention period of 12 months. Some families face great vulnerability due to various factors such as personal and familiar history, poverty, social isolation, etc. In such situations, the ability of parents to take care of their children can be rather limited and leads to situations of child-neglect. In Italy, in order to support vulnerable families, home care interventions are widespread. The research aim was to understand if and how the home care intervention is effective to answer the needs of these families. The use of assessment tools at different times of the intervention (T0, T1, T2) allowed the use of before-after comparison of measures that enabled us to evaluate the results, confirming the effectiveness of the intervention itself. at the same time, research used a variety of methods, using interviews, focus group, case-files analysis. All data collected were analyzed in relation to each other in a reflective process with research participants, considering not only outcomes of interventions, but rather also the procedural aspects and content of the interventions themselves, with the aim to try to identify the key factors fostering the adaptation of these families.

The exercises of singularity and plurality that lead to the new family structure force adults and children to call into question relationships, communication styles and the management of affections. The common goal of “making a new family” engages everyone in a pluralism of expressions that in the various forms of thought and project defines the educational intervention.

description: We investigate multiple Fano, comblike scattering resonances in single-layered, concentric core-shell nanoparticles composed of magnetic materials. Using the Lorenz-Mie theory, we derive, in the long-wavelength limit, an analytical condition for the occurrence of comblike resonances in the single scattering by coated spheres. This condition establishes that comblike scattering response uniquely depends on material parameters and thickness of the shell, provided that it is magnetic and thin compared to the scatterer radius. We also demonstrate that comblike scattering response shows up beyond the long-wavelength limit and it is robust against absorption. Since multiple Fano resonances are shown to depend explicitly on the magnetic permeability of the shell, we argue that both the position and profile of the comblike, morphology-dependent resonances could be externally tuned by exploiting the properties of engineered magnetic materials.

description: There is consensus among theorists and researchers from different areas, the importance of dialogue and complementarity between day care center and family in the education and care of young children. However, in the Brazilian context, recent research shows that while the legal guidelines link to the open spaces and practices that respect and enrich the presence of families in childcare, these indications are not sufficient and are still struggling to support the plurality of this meeting. So, this article aims to reflect about the process of configuration of the daycare center space in a better place to/for families. It argues the importance of spaces for families in daycare centers. Your organization enhances or limits participation. It must, however, go beyond materiality. It is crucial to look, identify and valorize the forms of occupation and the senses established between teachers, children and their families. The right of quality education in early childhood involves understanding the diversity of families as something enriching. Believes in recognition of plurality, in valorize of condition of otherness and belonging as the possibility of sustaining the meeting and provide the space of daycare somewhere to/for families. In dimension of experience in the pause time and meetings, places are constituted and constitutive. This is another opportunity to be and be in daycare center.

Community perceptions of malaria and vaccines in two districts of Mozambique
Creators: name: Lancaster, Kathryn

description: Abstract Background Malaria is a leading cause of mortality and morbidity in Mozambique, with nearly three-quarters of the country’s malaria-related deaths occurring in children younger than five years. A malaria vaccine is not yet available, but planning is underway for a possible introduction, as soon as one becomes available. In an effort to inform the planning process, this study explored sociocultural and health communications issues among individuals at the community level who are both responsible for decisions about vaccine use and who are likely to influence decisions about vaccine use. Methods Researchers conducted a qualitative study in two malaria-endemic districts in southern Mozambique. Using criterion-based sampling, they conducted 23 focus group discussions and 26 in-depth interviews. Implementation was guided by the engagement of community stakeholders. Results Community members recognize that malaria contributes to high death rates and affects the workforce, school attendance, and the economy. Vaccines are seen as a means to reduce the threat of childhood illnesses and to keep children and the rest of the community healthy. Perceived constraints to accessing vaccine services include long queues, staff shortages, and a lack of resources at health care facilities. Local leaders play a significant role in motivating caregivers to have their children vaccinated. Participants generally felt that a vaccine could help to prevent malaria, although some voiced concern that the focus was only on young children and not on older children, pregnant women, and the elderly. Probed on their understanding of vaccine efficacy, participants voiced various views, including the perception that while some vaccines did not fully prevent disease they still had important benefits. Overall, it would be essential for local leaders to be involved in the design of specific messages for a future malaria vaccine communications strategy, and for those messages to be translated into local languages. Conclusions Acceptance of routine childhood vaccines bodes well for a future malaria vaccine. Vaccinating children is a well-established routine that is viewed favourably in Mozambique. A communications strategy would need to build on existing immunization efforts and use trusted sources—including current government dissemination arrangements—to deliver health information.

description: This article presents an assessment of an automatic flight stabilization system that utilizes trim tabs. The system,knmvn asAST-1, was designed for the Polish military turboprop trainer aircraftPZL-130 Orlik. The AST-1 differs from traditionalautomatic flight control systems as it moves only the trim tabs of the primary control surfaces instead of the smfaces themselves. This solution offers benefits such as reduced complexity, cost, and energy consumption. The article describes the development of the AST-1 using model-based design and its evaluation through flight tests and hardware in the loop (HIL) simulations. The controller structure of the AST-1 system includes internal and external control loops with proportional-integral-derivative regulators. The system was tested in simulations at various levels of advancement, including model, software, and hardware in the loop simulations. The real flight data were com pared with hardware in the loop simulations results, where the controller software ran on the same onboard computer connected to actuators as in the actual aircraft. Flight tests were conducted to verify the control system, and various parameters were analysed to assess control quality, including step response analysis and the integral square error metric. The results of the flight tests were compared with the simulation results. The article provides detailed comparisons for the lateral control channel of the AST-1 system. Overall, the responses in real flight were stable and converged to setpoints, however they exhibited larger over/undershoots and settling times compared to the simulations. The discrepancies were attributed to factors such as air turbulence and the need for further refinement of the aerodynamic model to include asymmetrical effects. The article also suggests potentialimprovements to reduce the differences between simulationandrealflight, such as modifying the controller gains during flight and expanding the trim tab and primary control surface interaction model.

description: Adopting a mixed and integrated pedagogical model, this paper examines the roots of bullying in fraternal relationships in the family. Starting with some clinical considerations on the origins and causes of bullying, the paper argues and highlights the role of parental projections in determining the principles conflicts among children within the family. The argument is extended then to the analysis of some of the dynamics of bullying between siblings and to the link between these types of vicissitudes and bullying in the social context outside of the family. The paper concludes with some pedagogical considerations on the educational role of the family in the prevention of bullying.

description: The article displays a research investigating how much educational services for early childhood educators know about same-sex parenting families. This research involved 94 educators working in nursery schools in the Lucca area. The results highlight how prejudices and a general lack of information still persist on this issue. The article aims to offer a reflection on a mostly unknown reality, starting with the many data available. From the early Seventies up to today there are about 60 scientific surveys available on this issue. The opinion that kids need a mother and a father to be properly brought up doesn’t match with the results of the international report on family relations and psycho-social development of people.

description: Sandwich structures have been increasingly used due to their high strength-to-weight ratio and bending and buckling resistance. Today, it is possible to create topology-optimised structures with complex shapes using lattice structures through Additive Manufacturing technologies, avoiding the difficulties in coresheets adhesion in sandwich structures. In this paper, a 3D numerical model is proposed to assess the mechanical properties of hybrid lattice structures. A comparison between the overall response of a control surface of a tiltrotor aircraft with different cores for its sandwich panels will be studied. Specifically, two strut lattice cores and a conventional honeycomb lattice core are considered as options for the asymmetric sandwich panels.

description: We study N = 2 superconformal theories with gauge group SU(N) and 2N fundamental flavours in a locus of the Coulomb branch with a Z_N symmetry. In this special vacuum, we calculate the prepotential, the dual periods and the period matrix using equivariant localization. When the flavours are massless, we find that the period matrix is completely specified by [N/2] effective couplings. On each of these, we show that the S-duality group acts as a generalized triangle group and that its hauptmodul can be used to write a non-perturbatively exact relation between each effective coupling and the bare one. For N = 2, 3, 4 and 6, the generalized triangle group is an arithmetic Hecke group which contains a subgroup that is also a congruence subgroup of the modular group PSL(2,Z). For these cases, we introduce mass deformations that respect the symmetries of the special vacuum and show that the constraints arising from S-duality make it possible to resum the instanton contributions to the period matrix in terms of meromorphic modular forms which solve modular anomaly equations.

description: There is a wide application spectrum of deployable aeroshells for de-orbit and re-entry of space vehicles by using flexible heat shields. By expanding to a larger diameter prior to entry in order to increase drag, such a technology has shown to provide higher entry performance suitable for Earth or a variety of planetary high-speed entries that require high temperature thermal protection systems materials. Also, innovative shape-changing mechanisms exist in the literature for controlled re-entry and safe recovery of CubeSat class systems to recover payloads and data from LEO at low cost for post flight inspections and experimentations. Shape morphing during atmospheric entry could enable trajectory control by providing enhanced flight manoeuvrability and high-precision landing. This paper presents a CubeSat design concept that incorporates a mechanically deployable re-entry aeroshell within the standard l 2U form factor by investigating aerodynamics and heating of a flexible thermal protection system having shape-changing capabilities. Focus is given to the design of the deployment system through structural simulations. The deployable surface can be modulated by a single actuator in order to modulate the liftto-drag ratio for guided entry. Additionally, once deployed, the system can activate eight small movable aerodynamic flaps that can be individually morphed via a SMA-based actuation to control the trajectory and target the entry vehicle into the desired area for landing. This paper is framed within a joint research project for scientific and technological cooperation between Italy and Brazil in the field of space science, co-funded by the Italian Ministry of Foreign Affairs and International Cooperation (MAECI) and by CONF AP through the involved Brazilian State Funding Agencies (F APs ).

description: This study aims to highlight the significance of the family in education and, more specifically, in the reading process. If we consider the family’s influence in the creation and consolidation of their children’s reading habits, educational action should transcend beyond merely school-related activities and actions should be taken to promote reading for leisure, family and society in which it resides. After all, the foundations of education are consolidated through reading.
