The EU’s Biopolitical Governance of Advanced Therapy Medicinal Products

This paper focuses on the specific example of the newly operational Regulation on Advanced Therapy Medicinal Products to explore the potential for biopolitics, an arena in which biocitizens can demand and contest the exercise of EU power over life. The paper shows how the discourses producing, organizing and orchestrating citizen participation in the EU’s governance of advanced therapies from above figure a ‘deficit model’ of citizens in need of education inter alia through their membership of patients’ associations who have membership of the Committee on Advanced Therapies established by the Regulation. Biocitizens are shown to be incorporated to service the EU’s legitimacy needs. The paper then warns against assuming biocitizens’ (self-) reflexivity ensures they do not reiterate and reinforce their construction within the ‘deficit model’ by unwittingly deploying the terms of their subjection. After which the paper highlights some elements that provide a rhetorical and operational opening for participation, and which therefore can be used by biocitizens to reconstruct their engagement with EU governance from below, the wider governance of advanced therapies, as well as in their self-governance.

Unfractioned heparin therapy in infants and children

Unfractionated heparin is frequently used in tertiary pediatric centers for the prophylaxis and treatment of thromboembolic disease. Recent evidence suggests that the clinical outcomes of unfractionated heparin therapy in children are poor, as determined by target-range achievement and adverse-event rates. These reports of poor outcomes may be related to an age-dependent mechanism of action of unfractionated heparin. Furthermore, several published studies have indicated that unfractionated heparin–monitoring assays currently in clinical use have significant limitations that likely affect the safety and efficacy of anticoagulant management. This review summarizes the growing body of evidence suggesting that pediatric-specific recommendations for unfractionated heparin therapy management are required to improve clinical outcomes related to this commonly prescribed medication.

Neuropeptide YY1 receptor in human dental pulp cells of noncarious and carious teeth

Aim To determine the distribution of the NPY Y1 receptor in carious and noncarious human dental pulp tissue using immunohistochemistry. A subsidiary aim was to confirm the presence of the NPY Y1 protein product in membrane fractions of dental pulp tissue from carious and noncarious teeth using western blotting. Methodology Twenty two dental pulp samples were collected from carious and noncarious extracted teeth. Ten samples were processed for immunohistochemistry using a specific antibody to the NPY Y1 receptor. Twelve samples were used to obtain membrane extracts which were electrophoresed, blotted onto nitrocellulose and probed with NPY Y1 receptor antibody. Kruskal-Wallis one-way analysis of variance was employed to test for overall statistical differences between NPY Y1 levels in noncarious, moderately carious and grossly carious teeth. Results Neuropeptide Y Y1 receptor immunoreactivity was detected on the walls of blood vessels in pulp tissue from noncarious teeth. In carious teeth NPY Y1 immunoreactvity was observed on nerve fibres, blood vessels and inflammatory cells. Western blotting indicated the presence and confirmed the variability of NPY Y1 receptor protein expression in solubilised membrane preparations of human dental pulp tissue from carious and noncarious teeth. Conclusions Neuropeptide Y Y1 is expressed in human dental pulp tissue with evidence of increased expression in carious compared with noncarious teeth, suggesting a role for NPY Y1 in modulation of caries induced pulpal inflammation. © 2008 International Endodontic Journal.

Neuropeptides Regulate Expression of Angiogenic Growth Factors in Human Dental Pulp Fibroblasts

Abstract
INTRODUCTION:
Neuropeptides play an important role in inflammation and repair and have been implicated in mediating angiogenesis. Pulp fibroblasts express neuropeptide receptors, and the aim of this research was to investigate whether neuropeptides could regulate angiogenic growth factor expression in vitro
METHODS:
An angiogenic array was used to determine the levels of 10 angiogenic growth factors expressed by human pulp fibroblasts.
RESULTS:
Pulp fibroblasts were shown to express angiogenin, angiopoietin-2, epidermal growth factor, basic fibroblast growth factor, heparin-binding epidermal growth factor, hepatocyte growth factor, leptin, platelet-derived growth factor, placental growth factor, and vascular endothelial growth factor. Furthermore, the neuropeptides substance P, calcitonin gene-related peptide, vasoactive intestinal polypeptide, and neuropeptide Y altered angiogenic growth factor expression in vitro.
CONCLUSIONS:
The regulation of angiogenic growth factor expression by neuropeptides suggests a novel role for neuropeptides in pulpal inflammation and repair.

Re-treatment profiles during long-term maintenance therapy in a periodontal practice in Norway

Background: Periodontal therapy coupled with active maintenance has been shown to be effective in maintaining periodontal health, however, the question of re-treatment is rarely alluded to in the literature.
