Successful Treatment Using Simeprevir, Sofosbuvir and Rituximab of a Severe Form of Hepatitis C Virus-related Mixed Cryoglobulinemia with Cardiac Involvement

Numerous extrahepatic manifestations have been reported in hepatitis C virus (HCV) infection, particularly mixed cryoglobulinemia (MC). MC generally responds to clearance of HCV under pegylated-interferon plus ribavirin treatment. New direct-acting antiviral agents have been licensed for HCV under different combinations but have not been studied in severe forms of MC. Here, we present a case report describing a life-threatening form of MC with multivisceral involvement, which was successfully treated with concomitant rituximab, sofosbuvir and simeprevir. In light of the rapid clinical remission associated with sustained virological response and the excellent side-effect profile, this treatment should be considered as a first-line therapy in severe forms of MC.

Involvement of Mitochondrial Activity and OXPHOS in ATP Synthesis During the Motility Phase of Spermatozoa in the Pacific Oyster, Crassostrea gigas

In the Pacific oyster, spermatozoa are characterized by a remarkably long movement phase (i.e., over 24 h) sustained by a capacity to maintain intracellular ATP level. To gain information on oxidative phosphorylation (OXPHOS) functionality during the motility phase of Pacific oyster spermatozoa, we studied 1) changes in spermatozoal mitochondrial activity, that is, mitochondrial membrane potential (MMP), and intracellular ATP content in relation to motion parameters and 2) the involvement of OXPHOS for spermatozoal movement using carbonyl cyanide m-chlorophenyl hydrazone (CCCP). The percentage of motile spermatozoa decreased over a 24 h movement period. MMP increased steadily during the first 9 h of the movement phase and was subsequently maintained at a constant level. Conversely, spermatozoal ATP content decreased steadily during the first 9 h postactivation and was maintained at this level during the following hours of the movement phase. When OXPHOS was decoupled by CCCP, the movement of spermatozoa was maintained 2 h and totally stopped after 4 h of incubation, whereas spermatozoa were still motile in the control after 4 h. Our results suggest that the ATP sustaining flagellar movement of spermatozoa may partially originate from glycolysis or from mobilization of stored ATP or from potential phosphagens during the first 2 h of movement as deduced by the decoupling by CCCP of OXPHOS. However, OXPHOS is required to sustain the long motility phase of Pacific oyster spermatozoa. In addition, spermatozoa may hydrolyze intracellular ATP content during the early part of the movement phase, stimulating mitochondrial activity. This stimulation seems to be involved in sustaining a high ATP level until the end of the motility phase.

Alumni involvement in a technology program

Abstract: Everyone knows that in today's modern world, it is hard to keep up with the pace of the ever changing field of technology. This is no different in technology programs at the cegep level. Teachers who are employed at the cegep level find it difficult to keep up to date with the evolving industry trends, especially when working full time. In this paper, the involvement of alumni in the program is examined. The purpose of this study is to examine five areas of alumni involvement. These five major areas of alumni involvement are advisory committees, internships, field trips, guest speaking and real life projects. The literature is reviewed with respect to each of the described areas of involvement as well as theories of motivation. The shift of emphasis from teacher to student is discussed as well as the role of the teacher when faced with changes in technology. Finally students and alumni are surveyed to examine their perceptions to the various types of alumni involvement in the B.S.E.T. program. This research helps to describe whether and to what degree alumni involvement benefits our students in B.S.E.T. Several variables are examined, such as: academic satisfaction and alumni involvement; graduation year and academic satisfaction; graduation year and alumni involvement. The study also examines areas such as motivational attitudes of graduates to stay involved; areas where it is crucial for alumni to stay involved; desire to partner in a capstone project and area of involvement that tends to motivate students the most and that the graduates find of utmost importance.

Platform management and early supplier involvement in NPD

Platform strategies reflect a firm’s technology policy towards its new product development (NPD) activities. Depending on the technological complexities embedded in the platform, certain degree of interdependence is created between the firm and its suppliers. Firms may decide to what extent the suppliers should be involved in its NPD activities. There has been an increasing interest with issues related to supplier involvement in NPD. Involving suppliers early in NPD can help firms reduce costs, reduce concept-to-customer development time, improve quality, and provide innovative technologies. However, it requires a great effort and many tradeoffs need to be considered. This paper discusses the implications of early supplier involvement in new product development, specifically regarding to sourcing decisions and NPD processes when new components are designed and incorporated into the new platform. We would like to understand to what extent the NPD collaborates with suppliers, and at which stage of the NPD process suppliers are invited to participate in platform designs. A case study of Oticon, a Danish manufacturer of hearing aids, is presented. We describe how the successful introduction of a new platform of hearing aids is realized as well as how and when Oticon’s suppliers were involved during this process.

Effect of Melatonin and Analogues on Corneal Wound Healing: Involvement of Mt2 Melatonin Receptor

Purpose: We have investigated the effect of melatonin and its analogues on rabbit corneal epithelial wound healing. Methods: New Zealand rabbits were anaesthetised and wounds were made by placing Whatman paper discs soaked in n-heptanol on the cornea. Melatonin and analogues (all 10 nmol) were instilled. Wound diameter was measured every 2 hours by means of fluorescein application with a Topcon SL-8Z slit lamp. Melatonin antagonists (all 10 nmol) were applied 2 hours before the application of the n-heptanol-soaked disc and then every 6 hours together with melatonin. To confirm the presence of MT2 receptors in corneal epithelial cells immunohistochemistry, Western blot and RT-PCR assays in native tissue and in rabbit corneal epithelial cells were performed. The tear components were extracted then processed by HPLC to quantify melatonin in tears. Results: Migration assays revealed that melatonin and particularly the treatment with the MT2 agonist IIK7, accelerated the rate of healing (p < 0.001). The application of the non-selective melatonin receptor antagonist luzindole and the MT2 antagonist DH97 (but not prazosin), prevented the effect of melatonin on wound healing (both p < 0.001). Immunohistochemistry, Western blot and RT-PCR assays showed the presence of MT2 melatonin receptor in corneal epithelial cells. In addition, we have identified melatonin in tears and determined its daily variations. Conclusions: These data suggest that MT2 receptors are implicated in the effect of melatonin on corneal wound healing regulating migration rate. This suggests the potential use of melatonin and its analogues to enhance epithelial wound healing in ocular surface disease.

Representativeness, legitimacy and power in public involvement in health-care management

Public participation in health-service management is an increasingly prominent policy internationally. Frequently, though, academic studies have found it marginalized by health professionals who, keen to retain control over decision-making, undermine the legitimacy of involved members of the public, in particular by questioning their representativeness. This paper examines this negotiation of representative legitimacy between staff and involved users by drawing on a qualitative study of service-user involvement in pilot cancer-genetics services recently introduced in England, using interviews, participant observation and documentary analysis. In contrast to the findings of much of the literature, health professionals identified some degree of representative legitimacy in the contributions made by users. However, the ways in which staff and users constructed representativeness diverged significantly. Where staff valued the identities of users as biomedical and lay subjects, users themselves described the legitimacy of their contribution in more expansive terms of knowledge and citizenship. My analysis seeks to show how disputes over representativeness relate not just to a struggle for power according to contrasting group interests, but also to a substantive divergence in understanding of the nature of representativeness in the context of state-orchestrated efforts to increase public participation. This divergence might suggest problems with the enactment of such aspirations in practice; alternatively, however, contestation of representative legitimacy might be understood as reflecting ambiguities in policy-level objectives for participation, which secure implementation by accommodating the divergent constructions of those charged with putting initiatives into practice.

Whose health, whose care, whose say? Some comments on public involvement in new NHS commissioning arrangements

Recent health policy in England has demanded greater involvement of patients and the public in the commissioning of health and social care services. Public involvement is seen as a means of driving up service quality, reducing health inequalities and achieving value in commissioning decisions. This paper presents a summary and analysis of the forms that public involvement in commissioning are to take, along with empirical analysis from a qualitative study of service-user involvement. It is argued that the diversity of constituencies covered by the notion of ‘public involvement’, and the breadth of aims that public involvement is expected to achieve, require careful disaggregation. Public involvement in commissioning may encompass a variety of interest groups, whose inputs may include population needs assessment, evaluation of service quality, advocacy of the interests of a particular patient group or service, or a combination of all of these. Each of these roles may be legitimate, but there are significant tensions between them. The extent to which the structures for public involvement proposed recognize these possible tensions is arguably limited. Notably, new Local Involvement Networks (LINks), which will feed into commissioning decisions, are set as the arbiters of these different interests, a demanding role which will require considerable skill, tenacity and robustness if it is to be fulfilled effectively.

Cultural audit as a tool to increase employee involvement in small firms: A case study

Employee involvement is a common goal for most companies. This research started when managers of a familyrun horticultural firm decided to increase employee commitment and improve organizational climate. To help them, we considered the possibility of developing a cultural audit, adapting the tool to the fact that it was a small family business. Therefore, this paper will firstly review the existing literature concerning organizational culture, specially which cultural characteristics should be more valuable to achieve employee commitment and involvement and how to run a cultural audit. Secondly, it will expose the design and implementation of a cultural audit at this company, through an explicative case study that aims to compare the existing culture with the characteristics described theoretically. The study discusses the lack of trust, of a creative atmosphere, and of a shared vission, and suggests some recommendations to develop these characteristics, in order to gain the desired level of employee involvement. Key words: Employee involvement, organizational
