The role of olfactory ensheating cells in regenerative medicine: review of the literature
Authors: Grosu-Bularda Andreea , Manea Claudiu , Lascar Ioan 
Published: May 2015

Abstract
Olfactory ensheathing cells (OECs) join olfactory axons in their entrance to the central nervous system, representing a unique population of glial cells with functions in olfactory neurogenesis, axonal growth and olfactory bulb formation. Olfactory ensheathing cells have a great potential to induce repair for neural injuries, in central nervous system and peripheral nervous system, existing numerous experimental and clinical studies lately, reporting beneficial effects in anatomical and functional recovery. Studies are also conducted in order to establish possible pro-regenerative effects of the OECs, their potential in tissue repair and ability to modulate the immune system. The aim of this paper was to review the properties of olfactory ensheathing cells and their potential therapeutic role in regenerative medicine.
The role of inflammatory mediators in the pathogenesis of nasal polyposis: Literature review
Authors: Duda Roxana 
Published: May 2015

Abstract
Nasal polyposis represents a late stage of long-lasting inflammation of the sinonasal mucosa, characterized by increased inflammatory cells infiltration and anomalous tissue remodelling. A wide range of chemical mediators such as cytokines, chemokines, cell adhesion molecules are involved in the pathomechanism of nasal polyposis, but their significance has not been completely clarified.
Eosinophils are the dominant inflammatory cell population in nasal polyposis and are thought to be the central effector cells responsible for the onset and maintenance of the inflammatory process. Persistent inflammation of the sinonasal mucosa can lead to structural changes, such as epithelial damage, thickened basement membrane, stromal edema, formation of pseudocysts. This review summarizes prior and current knowledge regarding the involvement of the inflammatory process in the pathogenesis of nasal polyposis.

Tryptophan-Dependent Control of Colony Formation After DNA Damage via Sea3-Regulated TORC1 Signaling inSaccharomyces cerevisiae
Authors: Polleys Erica J , Bertuch Alison A 
Published: May 2015

AbstractThe Saccharomyces cerevisiaeIml1 complex inhibits TORC1 signaling and SEACAT antagonizes the Iml1 complex. Conditions in which SEACAT functions to inhibit Iml1 and, hence, TORC1 signaling, remain largely unknown. The SEACAT member Sea3 was linked previously to telomere maintenance and DNA repair via genome-wide genetic and physical interaction studies. Therefore, we questioned whether Sea3 functioned through TORC1 to influence these pathways. Deletion of SEA3 delayed the emergence of telomerase-independent survivors that use break-induced replication (BIR) to maintain their telomeres. Similarly, sea3∆ mutants exhibited a delay in colony formation in a BIR assay strain after double-strand break (DSB) induction as well as on the DNA-damaging agent bleomycin. Deletion of IML1 rescued the impaired growth of sea3∆ mutants after DNA damage, consistent with Sea3 functioning as a regulator of TORC1 signaling. The delay was not attributable to slowed DSB repair or termination of the DNA damage checkpoint but to tryptophan auxotrophy. High levels of tryptophan in yeast peptone dextrose media did not rescue the delay in colony formation, suggesting a defect in tryptophan import, although levels of the high-affinity tryptophan permease Tat2 were not perturbed in the sea3Δ mutant. Addition of quinolinic acid, an intermediate of the de novo NAD+ biosynthetic pathway, however, rescued the delay in colony formation in the sea3Δ mutant. Together, these findings highlight the importance of enforcement of TORC1 signaling and suggest that internal tryptophan levels influence growth recovery post DNA damage through the role of tryptophan in NAD+ synthesis.

Predicting Biofuel Invasiveness: A Relative Comparison to Crops and Weeds
Authors: Smith Larissa L. , Tekiela Daniel R. , Barney Jacob N. 
Published: May 2015

AbstractConcern raised against using highly competitive, exotic, large-statured, perennial grasses with fast growth rates as bioenergy crops has led to calls for risk assessment before widespread cultivation. Weed risk assessments (WRAs) are decision support tools commonly used throughout the world to determine the invasion risk of new plant taxa—primarily used as a pre-entry screen. Here, we compare the common Australian (A-WRA) and newer U.S. (US-WRA) models to evaluate the invasion risk of 16 candidate bioenergy crops and to compare their WRA scores to 14 important agronomic crops and 10 invasive species with an agronomic origin. Of the 40 species assessed, the A-WRA and US-WRA ranked 34 and 28 species, respectively, as high risk, including the major crops alfalfa, rice, canola, and barley. Surprisingly, in several cases, both models failed to effectively parse weeds from crops. For example, cereal rye received scores above (US-WRA) or comparable to (A-WRA) kudzu, a widespread damaging invader of the Southeastern United States introduced as forage. Our results indicate that these models are unable to accurately address broad, intraspecific variation and that species introduced for agronomic purposes pose special limitations to WRAs. This further supports other calls for postborder evaluation (e.g., field testing) following WRA screening. We should be cautious of the role of WRAs in setting policy, as illustrated by this relative evaluation of novel crops.
Demobilised Soldiersand Colonial Control: The British Policein Mandate Palestine and After
Authors: Hughes Matthew 
Published: May 2015

Demobilised Soldiers and Colonial Control: The British Police in Mandate Palestine and After Former soldiers filled the ranks of the British section of the Palestine police, veterans not just of the Great War but also of the war against rebels in Ireland (1919–1921). This is an empirical study of the harsh reality of service in the Palestine police for these tough, demobilised war veterans. This article details the violence of everyday policing, including torture and a «dirty war», mining archival sources and contextualising this material within the British use of collective punishment across the empire. The Palestine police failed in its job of policing, necessitating the deployment of the Army to Palestine; with this collapse in police control the force became more violent. The article argues that policing methods from the Mandate period –informed by war veterans – continued after the disbandment of the Palestine force in 1948, both within Israel and in other parts of the British Empire where former Palestine police officers went to serve in the 1950s. In telling the full story of policing in Palestine, this article extends our understanding of inter-war colonial policing, including its impact on local people, and it makes useful connections to other colonial powers operating in similar circumstances to the British in Palestine, which extend our knowledge of imperial and neo-imperial histories.
‘I can always rely on them’: the importance of social support for boys with haemophilia
Authors: Khair Kate , Gibson Faith , Meerabeau Liz 
Published: May 2015

Abstract
Background: Little is known about where, and from whom children with haemophilia receive support, as there is a paucity of psychosocial research on this topic. This paper, part of a larger study of living with haemophilia, discusses the importance of social support for boys with haemophilia. Methods: Data were collected from 30 boys aged 4-17 years with severe haemophilia A or B from a single Haemophilia Comprehensive Care Centre in the United Kingdom. Age appropriate participatory qualitative research techniques: photo-elicitation, draw and write, focus groups and individual interviews were used. All data were transcribed and the content was analysed using grounded theory. Results: Social support was gained in many ways from individuals who were identified by the study participants as supportive. These included parents, siblings (affected themselves or not), family members (who may also be affected) and friends. Being able to share experiences with others was also described as supportive. Conclusion: The boys in this study described many sources of social support, which changed over time as they grew older. Commentary, J Haem Pract 2014;1(1):23.
Boys and parents’ perceptions of living with haemophilia and an inhibitor
Authors: Phillott Anica 
Published: May 2015

Abstract
This study examined the perception of the quality of life in a small group of boys (aged 8-15) who have severe haemophilia and have also developed inhibitors and their parents. The study design was a qualitative research methodology using a phenomenology theory approach in order to gain perspectives from participants in a series of semi-structured interviews. The study showed that inhibitor development had an impact on the perceived quality of life of these boys and their families and in so doing threatened the coping mechanisms that had worked effectively for them in the past. Although there is adequate awareness among haemophilia treaters of the psychosocial impact of inhibitor development on family life, this may not always be seen as a priority when managing these boys. The study also identified gaps in the published evidence as well as scope for future study. Commentary, J Haem Pract 2014;1(1):23.
Physical function and quality of life in adolescents with haemophilia (SO-FIT study)
Authors: Khair Kate , Bladen Melanie , Holland Michael 
Published: May 2015

Abstract
Introduction: Self-completed measures of physical function and quality of life are increasingly being used in clinical practice yet little is known about how these measures correlate with joint scores in boys with severe haemophilia. In addition, it is not known whether currently used measures of functional outcome correlate with quality of life measures, which measure of physical function is most accurate and whether these measures are acceptable to a well treated contemporary cohort of boys. Methods: The Study Of physical Function In adolescenTs with haemophilia (SO-FIT) is a multicenter, randomized cross-over study designed to answer these questions, and to determine whether these self-reported measures are completed more fully and frequently if made available on mobile devices rather than with conventional pen and paper questionnaires. The study is being run by haemophilia nurse specialists and physiotherapists in UK haemophilia centres and will recruit 120 boys with severe haemophilia A or B, with or without inhibitors aged 8-16 years. Results:The SO-FIT study is now underway, and is expected to complete by the end of 2014.
Adherence to treatment in adolescents with haemophilia: a qualitative study
Authors: Müller-Kägi Elsbeth , Albisetti Manuela , Koppitz Andrea L. 
Published: May 2015

Abstract
introduction: Adolescents experience important changes in their physical, emotional, social and behavioural development. It is known that adolescents wish to be accepted by their peers, strive for independence and are prone to experiment. The challenge for adolescents with haemophilia is the need for taking responsibility for managing their illness and learning to comply with recommended treatment. This study aimed to investigate the process of adherence to treatment in adolescents with haemophilia. Methods: Grounded theory was used, based on one-on-one interviews (n=13) with adolescents with haemophilia. Results: The results include the core category “maturing selfcompetence” which represents the continuous developmental process from birth to teens with regard to haemophilia care. Three constitutive categories “living in a haemophiliac’s body”, “sharing with others” and “being protected and walking in faith” represent basic experiences in an adolescent's life. Further emergent categories include “becoming and staying informed”, “becoming and staying an expert”, “being in action”, “living between oblivion and awareness”, and “finding peace”. The adolescent stage “maturing self-competence” and their assessment of the situation at hand form the basis for decisions concerning adherence. Conclusion: Considering adolescents to be competent managers with regard to their disease, and including them in a partnership decision-making process for the therapeutic regime are the most important requisites for effective adherence.
Joint assessment in haemophilia – current physiotherapist practice in the UK
Authors: McLaughlin Paul , Bladen Melanie , Holland Mike , Khair Kate 
Published: May 2015

Abstract
Aim: UK guidelines recommend regular assessment of joint status in children with haemophilia using a standardised tool performed by haemophilia physiotherapists. We surveyed UK physiotherapists working in haemophilia care regarding their current practice with respect to joint scoring. Methods: A survey was posted on SurveyMonkey and all haemophilia physiotherapists practising in the UK were invited to respond. Responses were analysed and discussed at a roundtable meeting attended by invited physiotherapists and specialist haemophilia nurses. Results: In all, responses were received from 29 of the estimated 37 physiotherapists in the UK who see haemophilia patients. Both the survey and subsequent discussion reflected agreement that joint scoring offers a valuable tool to clinicians, but that better ways of assessing joint health were needed. There was enthusiasm for combining joint scoring with systematic and validated patient-reported outcome measures. Conclusion: Greater understanding is needed of the relationship between joint scores and measures of physical function and quality of life.

Determinants of Public Sector Innovation: The Example of Capacity Development in Public Procurement
Authors: Otter Nils , Weber Mike 
Published: May 2015

The Triple-Helix-Model stresses the idea that a successful national system of innovation ought to incorporate the complexity of three social subsystems: private sector economy, governmental system and science. Following the insight that the state and its agencies are important players in any system of innovation, we take a closer look at the innovative action in the public sphere. Therefore, we propose an analytical tool that allows a more detailed explanation of relevant determinants of innovative behaviour: (1) property rights, (2) capabilities, and (3) motivation. In order to show the relevance of these determinants, we tested the plausibility of our theoretical tool against the topic of public procurement of innovation. Five hypotheses were derived and then tested empirically by using a data set about German public procurement practice. Our linear regression model provides evidence for the hypotheses that framework conditions, special training, and motivation of procurement staff play a central role in demand-driven innovation of the public sector.

Pravica do pravnega sredstva je ena temeljnih pravic, ki mora biti zagotovljena vsakemu udeležencu v postopku (kazenskem, upravnem,pravdnem …), v katerem se odloča o njegovih pravicah, dolžnostih ali pravnih koristih. Na področju prekrškovnega prava v hitrem prekrškovnem postopku je zakonodajalec to pravno sredstvo poimenoval zahteva za sodno varstvo. Njena učinkovitost zagotavljanja pravne varnosti kršiteljev je neraziskana, zato je bila opravljena poglobljena empirična, historična in normativna raziskava izpodbojnih razlogov za njeno vložitev, zlasti njihovega nabora, pomena, obsega in pogostosti njihove vložitve. Ugotovil sem, da se nabor izpodbojnih razlogov za vložitev zahteve sodnega varstva širi s spremembami Zakona o prekrških. Največ zahtev je vloženih zaradi izpodbojnega razloga zmotne in nepopolne ugotovitve dejanskega stanja. To pomeni, da se prekrškovnemu organu v tem delu hitrega prekrškovnega postopka očita največ nepravilnosti.

Commentary: Periodontitis and Rheumatoid Arthritis: What Do We Know?
Authors: de Smit Menke J. , Westra Johanna , Brouwer Elisabeth , Janssen Koen M.J. , Vissink Arjan , van Winkelhoff Arie Jan 
Published: May 2015

Background: Currently, in the field of rheumatology, there is much attention given towards the possible causality between periodontitis and rheumatoid arthritis (RA), specifically regarding the role of Porphyromonas gingivalis (Pg). This bacterium is unique, having a citrullinating enzyme. Antibodies against citrullinated proteins are rather specific for RA.Methods: Because causality is ultimately tested in longitudinal cohort studies which currently do not exist for periodontitis and RA, this commentary applied Bradford Hill criteria on the existing literature to assess causality as the most likely interpretation of this association.Conclusions: From an epidemiologic point of view, patients with RA have a higher incidence of periodontal disease than individuals without RA. In addition, there is a dose‐response pattern in the association between the severity of periodontitis and RA disease activity. There are indications that periodontitis precedes RA, but there is no evidence yet available to show that Pg plays a direct role in this temporal relationship. The role of the unique characteristic of citrullination by Pg remains unexplained. However, in animal models, citrullination by Pg plays a distinct role in the development and aggravation of experimental arthritis. Although the role of Pg in RA remains speculative, a causative role for periodontitis as a chronic inflammatory disease caused by infectious agents in RA seems biologically plausible.
Completion Design for Gas Well Deliquification
Authors: Montero Gustavo Daniel 
Published: May 2015

Abstract
The maturation of gas fields requires solutions to sustain optimal production flow rates. The decrease of pressure in gas reservoirs, excluding dry gas reservoirs, brings about the great challenge of unloading liquid accumulated in the bottomhole, known as gas well deliquification, in order to prevent the decrease of gas flow rate due to the back pressure set up by the liquid column.
Wells' production history normally shows, after an initial period, a regular decline in the gas flow rate and a steady liquid flow rate, resulting in a decreasing gas liquid relationship. This causes the multiphase flow regime to change throughout the life of the well. At some point, below the critical gas flow rate, liquid loading will result in an important gas flow rate reduction, and invariably will end up killing the well.
This work presents an experience of performance optimization of the completion design, which had been run during completion without killing the well.
Several alternatives were evaluated and opted for the one which offered greater versatility. Two main objectives were established:
– Use of regular and well-known bottomhole tools, to decrease the possibility of mechanical failure – Use of regular tubing diameter and flow passages, with two purposes: to decrease the possibility of plugs formation by any mean and to keep the possibility of monitoring downhole behavior through slick line measurements
Shows the implementation of an innovative, economical, autonomous design (doesn't require energy), which demands low bottomhole dynamic pressure, and which allows the constant discharge of liquid from a large casing section.
