TL;DR: Results indicate that lymphocyte-like cells are circulating undifferentiated cells recognised by anti-CD34 antibody and there are at least two defined haemocyte differentiation pathways.
Abstract: In the present study, we carried out a detailed light microscopy investigation of the cytochemical properties of the haemocytes of the colonial ascidian Botryllus schlosseri, using new cytochemical stains and enzymatic markers, a panel of antibodies and lectins as probes to characterise Botryllus blood cells further. Results indicate that lymphocyte-like cells are circulating undifferentiated cells recognised by anti-CD34 antibody and there are at least two defined haemocyte differentiation pathways: i) phagocytes, represented by hyaline amoebocytes and macrophage-like cells, which share similar staining properties, the same hydrolytic enzyme content as well as the presence of detectable cytochrome-c-oxidase activity, recognition by anti-CD39 and Narcissus pseudonarcissus agglutinin; ii) cytotoxic cell line, represented by granular amoebocytes and morula cells which have vacuoles stained by Ehrlich's stain and Neutral Red; DOPA-containing protein are present inside morula cell vacuoles. Pigment cells and nephrocytes are involved in catabolite storage but their relationships with other cell types are less clear.

TL;DR: It is reported that in the minimal supersymmetric standard model (mH+/-, tanbeta) plane the first exclusion regions with radiative and Yukawa coupling corrections are presented, allowing 95% C.L. upper limits to be placed on BR(t-->H+b) for different charged Higgs decay scenarios.
Abstract: We report the results of a search for a charged Higgs boson in the decays of top quarks produced in pp collisions at a center-of-mass energy of 1.96 TeV. We use a data sample corresponding to an integrated luminosity of 193 pb{sup -1} collected by the upgraded Collider Detector at Fermilab. No evidence for charged Higgs production is found, allowing 95% C.L. upper limits to be placed on BR(t{yields}H{sup +}b) for different charged Higgs decay scenarios. In addition, we present in the minimal supersymmetric standard model (m{sub H{sup {+-}}},tan{beta}) plane the first exclusion regions with radiative and Yukawa coupling corrections.

TL;DR: In this paper, the authors explore how a dipolar+quadrupolar star-centred field influences the properties of the observed light curves and compare the results with the Chandra and XMM-Newton observations.
Abstract: Recent Chandra and XMM–Newton observations of a number of X-ray ‘dim’ pulsating neutron stars have revealed quite unexpected features in the emission from these sources. Their soft thermal spectrum, believed to originate directly from the star surface, shows evidence for a phase-varying absorption line at some hundred eVs. The pulse modulation is relatively large (pulsed fractions in the range ∼12–35 per cent), the pulse shape is often non-sinusoidal, and the hard X-ray colour appears to be anticorrelated in phase with the total emission. Moreover, the prototype of this class, RX J0720.4−3125, has been found to undergo rather sensible changes in both its spectral and timing properties over a time-scale of a few years. All these new findings seem difficult to reconcile with the standard picture of a cooling neutron star endowed with a purely dipolar magnetic field, at least if surface emission is produced in an atmosphere on top of the crust. In this paper we explore how a dipolar+quadrupolar star-centred field influences the properties of the observed light curves. The phase-resolved spectrum has been evaluated accounting for both radiative transfer in a magnetized atmosphere and general relativistic ray-bending. We computed over 78 000 light curves, varying the quadrupolar components and the viewing geometry. A comparison of the data with our model indicates that higher-order multipoles are required to reproduce the observations.

TL;DR: In this paper, the authors studied the relationship between firms' upstream and downstream internationalization and their propensity to introduce products or processes that reduce environmental impact, and found that firms that outsource to and rely on non-local suppliers are less likely to engage in environmental innovations.
Abstract: Based on original data on Italian firms specializing in medium- and low-tech industries, we study the relationship between firms’ upstream and downstream internationalization and their propensity to introduce products or processes that reduce environmental impact. Preliminary evidence suggests that geography plays an important role in green firms’ activities and supply chains. More precisely, results suggest that firms that outsource to and rely on non-local suppliers are less likely to engage in environmental innovations. Moreover, we verify that firms engaged in export activities play a similar and negative role, regardless of the export intensity and typology of foreign markets (i.e. developed versus emerging). Tapping global flows of knowledge by being a part of a multinational group positively spurs the development of green innovations, as for FDIs.

TL;DR: Patients in this population-based cohort of unselected patients with UC were treated more aggressively with immunomodulators and biological therapy than in cohorts from the previous two decades, but their disease outcomes, including colectomy rates, were no different.
Abstract: Background and aims Few population-based cohort studies have assessed the disease course of ulcerative colitis [UC] in the era of biological therapy and widespread use of immunomodulators. The aim of this study was to assess the 5-year outcome and disease course of patients with UC in the Epi-IBD cohort. Methods In a prospective, population-based inception cohort of unselected patients with UC, patients were followed up from the time of their diagnosis, which included the collection of their clinical data, demographics, disease activity, medical therapy, and rates of surgery, cancers, and deaths. Associations between outcomes and multiple covariates were analysed by Cox regression analysis. Results A total of 717 patients were included in the study. During follow-up, 43 [6%] patients underwent a colectomy and 163 [23%] patients were hospitalised. Of patients with limited colitis [distal to the left flexure], 90 [21%] progressed to extensive colitis. In addition, 92 [27%] patients with extensive colitis experienced a regression in disease extent, which was associated with a reduced risk of hospitalisation (hazard ratio [HR]: 0.5 95% CI: 0.3-0.8]. Overall, patients were treated similarly in both geographical regions; 80 [11%] patients needed biological therapy and 210 [29%] patients received immunomodulators. Treatment with immunomodulators was found to reduce the risk of hospitalisation [HR: 0.5 95% CI: 0.3-0.8]. Conclusions Although patients in this population-based cohort were treated more aggressively with immunomodulators and biological therapy than in cohorts from the previous two decades, their disease outcomes, including colectomy rates, were no different. However, treatment with immunomodulators was found to reduce the risk of hospitalisation.
