Role of aldosterone availability in preeclampsia

Preeclampsia is a hypertensive disorder unique to pregnancy and remains the leading cause of maternal and fetal morbidity and mortality. Despite active research, the etiology of this disease remains still an enigma. There is increasing evidence that a combination of several factors is responsible for the development of preeclampsia. In this review, we discuss the role of aldosterone in the regulation of body fluid in pregnancy and preeclampsia. Aldosterone is produced by the enzyme aldosterone synthase and competes with cortisol and progesterone for the mineralocorticoid receptor, thus affecting sodium reabsorption and maternal volume expansion. Aldosterone seems to play a pivotal role in controlling blood pressure during pregnancy and to contribute to the well-being of the mother-to-be. Novel findings in understanding the underlying causes of preeclampsia provide a rationale for future novel prophylactic and therapeutic interventions in the treatment of this pregnancy-associated disease.

The role of lymphadenectomy in high risk prostate cancer

Historically, patients with high risk prostate cancer were considered poor candidates for radical prostatectomy (RP) due to the likelihood of positive pelvic lymph nodes and decreased long term survival. Although there is still no consensus on the optimal therapy for this group of patients, there is increasing evidence that surgery could play a role. Cancer specific survival (CSS) rates after RP for locally advanced disease at 10 year follow up range from 29 to 72%, depending on tumor differentiation. The role of pelvic lymph node dissection (PLND) in prostate cancer remains a controversial topic. Nonetheless, in conjunction with RRP extended PLND (ePLND) should be performed as extended lymph node dissection in lieu of standard PLND may increase staging accuracy, influence decision making with respect to adjuvant therapy and possibly impact outcome. High risk patients with organ confined prostate cancer and low volume (micro)metastatic disease may be the ones to profit most from this approach.

The role of muscle flap in preventing bronchus stump insufficiency after pneumonectomy for malignant pleural mesothelioma in high-risk patients

Bronchus stump insufficiency (BSI) is one of the major complications after pneumonectomy; we analyzed all patients who underwent extra pleural pneumonectomy (EPP) for malignant pleural mesothelioma (MPM) in order to detect the role of muscle flap (MF) on preventing early and late stump insufficiency. From January 2000 until December 2005, there were 42 patients admitted with MPM for further intervention at our institution. Thirty patients were suitable for surgery and thus received a multimodal treatment with neo-adjuvant chemotherapy using Cisplatin and Gemcitabin (Gemzar), EPP followed by 54 Gray (Gy) adjuvant radiotherapy. Data were collected from the surgical and oncological records. There were 37 male patients (88%), the median age was 65 years (range 40-83 years). Seven (17%) patients had concomitant diseases. Forty patients (95%) had asbestos exposition. The operative procedures were EPP with muscle flap through an anterolateral thoracotomy. Univariate and multivariate analyses were done. One patient (3%) died on the 2nd postoperative day due to lung embolism. Mild complications were noticed in the early postoperative phase in 8 (25%) patients. There was no early or late stump insufficiency during the 15-month follow-up. Surgical techniques using muscle flap seems to play a major role in the prevention of bronchus stump insufficiency especially after neo-adjuvant chemotherapy.

Role of glial cells in the functional expression of LL-37/rat cathelin-related antimicrobial peptide in meningitis

Antimicrobial peptides are intrinsic to the innate immune system in many organ systems, but little is known about their expression in the central nervous system. We examined cerebrospinal fluid (CSF) and serum from patients with active bacterial meningitis to assess antimicrobial peptides and possible bactericidal properties of the CSF. We found antimicrobial peptides (human cathelicidin LL-37) in the CSF of patients with bacterial meningitis but not in control CSF. We next characterized the expression, secretion, and bactericidal properties of rat cathelin-related antimicrobial peptide, the homologue of the human LL-37, in rat astrocytes and microglia after incubation with different bacterial components. Using real-time polymerase chain reaction and Western blotting, we determined that supernatants from both astrocytes and microglia incubated with bacterial component supernatants had antimicrobial activity. The expression of rat cathelin-related antimicrobial peptide in rat glial cells involved different signal transduction pathways and was induced by the inflammatory cytokines interleukin 1beta and tumor necrosis factor. In an experimental model of meningitis, infant rats were intracisternally infected with Streptococcus pneumoniae, and rat cathelin-related antimicrobial peptide was localized in glia, choroid plexus, and ependymal cells by immunohistochemistry. Together, these results suggest that cathelicidins produced by glia and other cells play an important part in the innate immune response against pathogens in central nervous system bacterial infections.

The Role of Small and Medium-sized Centers for Territorial Development in Switzerland

This paper describes the role of small and medium-sized urban centers in Switzerland. Switzerland is a highly urbanized country where small and medium-sized urban centers play an important role in ensuring a balanced national urban system. Besides the four largest metropolitan regions （Zurich, Geneva, Basel and Bern）, small and medium-sized towns function as central places for a wider, often extensive hinterland. They provide opportunities for living and working and they connect rural and mountain regions to national and international networks. Using secondary statistics and a case study, the paper shows that small and medium-sized urban centers are home to significant concentrations of export-oriented industries. Firms in these value-adding secondary sectors are rooted in these places and benefit from strong local embeddedness while also being oriented towards global markets. Small and medium-sized urban centers also profit from their strong local identities. While these places face various challenges, they function as important pillars in creating a balanced regional development pattern. Swiss regional development policy follows the goal of polycentric spatial development and it employs various instruments that aim to ensure a balanced urban system.

Possible role of Cdx2 in the serrated pathway of colorectal cancer characterized by BRAF mutation, high-level CpG Island methylator phenotype and mismatch repair-deficiency

Colorectal cancer is a heterogeneous disease at the histomorphological, clinical and molecular level. Approximately 20% of cases may progress through the "serrated" pathway characterized by BRAF mutation and high-level CpG Island Methylator Phenotype (CIMP). A large subgroup are additionally microsatellite instable (MSI) and demonstrate significant loss of tumor suppressor Cdx2. The aim of this study is to determine the specificity of Cdx2 protein expression and CpG promoter hypermethylation for BRAF(V600E) and high-level CIMP in colorectal cancer. Cdx2, Mlh1, Msh2, Msh6, and Pms2 were analyzed by immunohistochemistry using a multi-punch tissue microarray (TMA; n = 220 patients). KRAS and BRAF(V600E) mutation analysis, CDX2 methylation and CIMP were investigated. Loss of Cdx2 was correlated with larger tumor size (P = 0.0154), right-sided location (P = 0.0014), higher tumor grade (P < 0.0001), more advanced pT (P = 0.0234) and lymphatic invasion (P = 0.0351). Specificity was 100% for mismatch repair (MMR)-deficiency (P < 0.0001), 92.2% (P < 0.0001) for BRAF(V600E) and 91.8% for CIMP-high. Combined analysis of BRAF(V600E) /CIMP identified Cdx2 loss as sensitive (80%) and specific (91.5%) for mutation/high status. These results were validated on eight well-established colorectal cancer cell lines. CDX2 methylation correlated with BRAF(V600E) (P = 0.0184) and with Cdx2 protein loss (P = 0.0028). These results seem to indicate that Cdx2 may play a role in the serrated pathway to colorectal cancer as underlined by strong relationships with BRAF(V600E) , CIMP-high and MMR-deficiency. Whether this protein can only be used as a "surrogate" marker, or is functionally involved in the progression of these tumors remains to be elucidated.

Knowledge and valuation of Andean agroforestry species: the role of sex, age, and migration among members of a rural community in Bolivia

Background Agroforestry is a sustainable land use method with a long tradition in the Bolivian Andes. A better understanding of people’s knowledge and valuation of woody species can help to adjust actor-oriented agroforestry systems. In this case study, carried out in a peasant community of the Bolivian Andes, we aimed at calculating the cultural importance of selected agroforestry species, and at analysing the intracultural variation in the cultural importance and knowledge of plants according to peasants’ sex, age, and migration. Methods Data collection was based on semi-structured interviews and freelisting exercises. Two ethnobotanical indices (Composite Salience, Cultural Importance) were used for calculating the cultural importance of plants. Intracultural variation in the cultural importance and knowledge of plants was detected by using linear and generalised linear (mixed) models. Results and discussion The culturally most important woody species were mainly trees and exotic species (e.g. Schinus molle, Prosopis laevigata, Eucalyptus globulus). We found that knowledge and valuation of plants increased with age but that they were lower for migrants; sex, by contrast, played a minor role. The age effects possibly result from decreasing ecological apparency of valuable native species, and their substitution by exotic marketable trees, loss of traditional plant uses or the use of other materials (e.g. plastic) instead of wood. Decreasing dedication to traditional farming may have led to successive abandonment of traditional tool uses, and the overall transformation of woody plant use is possibly related to diminishing medicinal knowledge. Conclusions Age and migration affect how people value woody species and what they know about their uses. For this reason, we recommend paying particular attention to the potential of native species, which could open promising perspectives especially for the young migrating peasant generation and draw their interest in agroforestry. These native species should be ecologically sound and selected on their potential to provide subsistence and promising commercial uses. In addition to offering socio-economic and environmental services, agroforestry initiatives using native trees and shrubs can play a crucial role in recovering elements of the lost ancient landscape that still forms part of local people’s collective identity.

How nice is good for patients and for therapy outcome? The role of confrontation in the process of psychotherapy

It is well established that the therapeutic relationship contributes about as much to therapy outcome as 'technical' intervention. Furthermore, it follows clear prescriptive concepts in the same manner as technical interventions do. 'Motive Oriented Therapeutic Relationship' is such a concept for establishing a solid basis for whatever therapeutic work the patients' problems require (Grawe, 1980, 1992; Caspar, 1996). Yet, the therapeutic relationship doesn't explain everything because other factors play a significant role too. Previous studies showed that outcome is clearly better when therapists achieved a generally high quality of a therapeutic relationship when they did not shy away from possibly threatening interventions such as confrontations. This ratio of a fruitful alliance and marginally present confrontations in the same session also showed significant correlations with patient's assessment of alliance and progress in therapy (Figlioli et al., 2009).Aim: The current state of research in the field does not give any answers to questions like how good and bad confrontations can be characterized or what role does the intensity, respectively frequency of confrontations play in the process of psychotherapy. Methods: A sample of 80 therapies of 3 sessions each representing either good or bad outcome was judged moment by moment by independent raters if and how therapists used confrontative interventions. Results: Preliminary analyses show that successful confrontations are explicitly uttered, short but intense, related to important patients goals in therapy and embedded in prior complementarity. Discussion: The results will be discussed in terms of their implications for the clinical daily work.

The role of learning-related dopamine signals in addiction vulnerability

Dopaminergic signals play a mathematically precise role in reward-related learning, and variations in dopaminergic signaling have been implicated in vulnerability to addiction. Here, we provide a detailed overview of the relationship between theoretical, mathematical, and experimental accounts of phasic dopamine signaling, with implications for the role of learning-related dopamine signaling in addiction and related disorders. We describe the theoretical and behavioral characteristics of model-free learning based on errors in the prediction of reward, including step-by-step explanations of the underlying equations. We then use recent insights from an animal model that highlights individual variation in learning during a Pavlovian conditioning paradigm to describe overlapping aspects of incentive salience attribution and model-free learning. We argue that this provides a computationally coherent account of some features of addiction.

The role of brand marketing in snowboarding: A comparative study of Switzerland and New Zealand

Introduction: Brands play an essential role in the organizational structure of snowboarding by sponsoring athletes, arranging events, contributing to product development and developing long-term partnerships with other key actors. However, the specialities of their role in scene sports, such as creating identities, networking and brand marketing strategies, have not been extensively researched. This study aims to provide an analysis of the function of brands within the snowboarding subculture by comparing how the sport is organized in Switzerland and New Zealand. Sociological theories of subcultures (Hitzler & Niederbacher, 2010) and social networks (Stegbauer, 2008) are used to defi ne the structures of the sport, whereas marketing and branding theories (Adjouri & Stastny, 2006) help to understand the role of the brands. Snowboarding will be defi ned as an alternative sports subculture based on characteristics such as aesthetics, adventure and new resources of performance (Schwier, 2006). Such a defi nition also begs for a novel form of analyzing its organization. Unlike more conventional structures, the organization of snowboarding allows a variety of actors to get involved in leading the sport. By portraying and encouraging differentiated identities and lifestyles, athletes provide a space for other actors to fi nd their place within the sport (Wheaton, 2005). According to Stegbauers network theory, individual actors are able to obtain high positions and defi ne their identity depending on their ties to actors and networks within the subculture (Stegbauer, 2008). For example, social capital, contacts within the sport and insider knowledge on subculture-related information enable actors to get closer to the core (Hitzler & Niederbacher, 2010). Actors who do not have close networks and allies within the subculture are less likely to engage successfully in the culture, whether as an individual or as a commercial actor (Thorpe, 2011). This study focuses on the organizational structure of snowboarding by comparing the development of the sport in Switzerland and New Zealand. An analysis of snowboarding in two nations with diverse cultures and economic systems allows a further defi nition of the structural organization of the sport and explains how brands play an important role in the sport. Methods: The structural organization of the sport will be analyzed through an ethnographic approach, using participant observation at various leading events in Switzerland (Freestyle.ch, European Open) and New Zealand (World Heli Challenge, New Zealand Open, New Zealand Winter Games). The data is analyzed using grounded theory (Glaser & Strauss 1967) and gives an overview of the actors that are playing an important role in the local development of snowboarding. Participant observation was also used as a tool to get inside the sport culture and opened up the possibility to make over 40 semi-structured qualitative expert interviews with international core actors from 11 countries. Obtaining access to one actor as a partner early on helped to get inside the local sport culture. The ‘snowball effect’ allowed the researcher to acquire access, build trust and conduct interviews with experts within the core scene. All the interviewed actors have a direct infl uence on the sport in one or both countries, which permit a cross-analysis. The data of the interviews was evaluated through content analysis (Mayring 2010). The two methods together provided suffi cient data to analyze the organizational structure and discuss the role of brand marketing within snowboarding. Results: An actors mapping by means of a center-periphery framework has identifi ed fi ve main core groups: athletes, media representatives, brand-marketing managers, resort managers and event organizers. In both countries the same grouping of actors were found. Despite possessing different and frequently multiple roles and responsibilities, core actors appear to have a strong common identifi cation as ‘snowboarders’, are considered to be part of the organizational elite of the sport and tend to advocate similar goals. The author has found that brands in Switzerland tend to have a larger impact on the broader snowboarding culture due to a number of factors discussed below. Due to a larger amount of snowboarders and stronger economic power in Europe, snowboarders are making attempts to differentiate themselves from other winter sports, while competing with each other to develop niche markets. In New Zealand, on the other hand, the smaller market enables more cooperation and mutual respect within snowboarders. Further they are more closely linked to other winter sports and are satisfi ed with being lumped together. In both countries, brands have taken up the role of supporting young athletes, organizing competitions and feeding media with subculture-related content. Brands build their image and identity through the collaboration with particular athletes who can represent the values of the brand. Local and global communities with similar lifestyles and interests are being built around brands that share a common vision of the sport. The dominance of brands in snowboarding has enabled them with the power to organize and rule the sport through its fan base and supporters. Brands were defi ned by interviewees as independent institutions led by insiders who know the codes and symbols of the sport and were given trust and credibility. The brands identify themselves as the engines of the sport by providing the equipment, opportunities for athletes to get exposure, allowing media to get exclusive information on activities, events and sport-related stories. Differences between the two countries are more related to the economic system. While Switzerland is well integrated in the broader European market, New Zealand’s geographical isolation and close proximity to Australia tends to limit its market. Further, due to different cultural lifestyles, access to resorts and seasonal restrictions, to name a few, the amount of people practicing winter sports in New Zealand is much smaller than in Switzerland. However, this also presents numerous advantages. For example, the short southern hemisphere winter season in New Zealand enables them to attract international sports athletes, brands and representatives in a period when Europe and North America is in summer. Further, the unique snow conditions in New Zealand and majestic landscape is popular for attracting world renowned photo- and cinematographers. Another advantage is the less populated network as it provides the opportunity for individuals to gain easier access to the core of the sport, obtain diverse positions and form a unique identity and market. In Switzerland, on the other hand, the snowboarding network is dense with few positions available for the taking. Homegrown brands with core recognition are found in both countries. It was found that the Swiss brands tend to have a larger impact on the market, whereas in New Zealand, the sport is more dependent on import products by foreign brands. Further, athletes, events and resorts in New Zealand are often dependent on large brand sponsorships from abroad such as from brand headquarters in the Unites States. Thus, due to its location in the centre of Europe, Swiss brands can take advantage of brands which are closer in proximity and culture to sponsor athletes and events. In terms of media coverage, winter sports in New Zealand tend to have a minor coverage and tradition in local mass media, which leads to less exposure, recognition and investment into the sport. This is also related to how snowboarding is more integrated into other winter sports in New Zealand. Another difference is the accessibility of the ski resort by the population. While in Switzerland the resorts are mostly being visited by day-travelers, ‘weekend warriors’ and holiday makers, the location of the resorts in New Zealand make it diffi cult to visit for one day. This is in part due to the fact that Swiss ski resorts and villages are usually the same location and are accessible through public transportation, while the ski resorts in New Zealand have been built separately from the villages. Further, the villages have not been built to accommodate to high tourist arrivals. Thus, accommodation and food facilities are limited and there is a lack of public transportation to the resorts. Discussion: The fi ndings show that networks and social relations combined with specifi c knowledge on scene-related attributes are crucial in obtaining opportunities within the sport. Partnerships as well as competition between these different actors are necessary for core acceptance, peer credibility and successful commercial interests. Brands need to maintain effective marketing strategies and identities which incorporate subcultural forms of behavior and communication. In order to sustain credibility from its fans, athletes and other snowboarding actors, brands need to maintain their insider status through social networks and commercial branding strategies. The interaction between all actors is a reciprocated process, where social capital, networks and identities are being shared. While the overall structure of snowboard subcultures in Europe and New Zealand are similar, there are some distinct characteristics which make each one unique. References Adjouri, N. & Stastny, P.

The role of commercial actors in snowboarding

Commercial actors play an essential role in the organisational structure of snowboarding by sponsoring athletes, arranging events, contributing to product development and developing long-term partnerships with other key actors. However, the particularities of their role in the alternative sports cultures which are related to brand marketing strategies have not been extensively researched. Based on Hitzler and Niederbachers (2010) framework of social scenes, Stegbauers (2008) social network and Adjouri and Stastnys (2006) branding theories, analysis is carried out using an ethnographic approach. This includes participant observation of relevant events and semi-structured interviews with over forty key actors of the sport to examine the roles and activities of core actors within snowboarding. The findings reveal that brands have gained an important position within the scene; where they can build partnerships with other core and periphery actors in order to market particularly identities, lifestyles and products. This contributes to the development of a sport which is dependent on brands for its continuity. By using promotional strategies of sponsoring athletes, organising events and feeding media with scene-related content, the aesthetical values of the snowboarding sport are communicated and transferred, while ensuring exposure of the brand’s image and lifestyle. Social contacts as well as knowledge on particularities of the sport allow the commercial actors to gain an influential position and identity within the snowboarding core culture.

FUS protein interacts with U7 snRNP and plays a role in replication-dependant histone genes expression

The U7 small nuclear ribonucleoprotein (U7 snRNP) is an essential factor mediating the unique 3’end processing of non-polyadenylated, replication-dependent histone mRNAs in metazoans. These histone genes expression and processing of their transcripts are cell cycle-regulated mechanisms that recruit a number of specific proteins as well as common factors required for expression and maturation of polyadenylated mRNAs. However, despite all the knowledge we have so far, there are still gaps in understanding of core histone RNA 3’ end processing, its coupling to transcription and regulation during cell cycle. To further elucidate this phenomena we used affinity chromatography based on tagged version of U7 snRNA molecule to identify proteins associated with U7 snRNP/U7 snRNA that could be potentially involved in core histone genes expression in human cells. Mass spectrometric analysis of affinity-purified fraction revealed, among others, multifunctional RNA/DNAbinding protein FUS/TLS (fused in sarcoma/translocated in liposarcoma) as a new factor interacting with U7 snRNA/RNP. Co-immunoprecipitation and RIP experiments confirmed the binding between FUS and the U7 RNA/snRNP. Interestingly, FUS:U7 snRNA interaction seems to be activated in S phase where the core histone genes are expressed. Moreover, FUS co-fractionates in 10-50% continuous glycerol gradient with other factors involved in histone premRNAs 3’end processing. However, this unique 3’end maturation was not disturbed upon FUS knockdown. Instead, we found that FUS depletion leads to a de-regulation of expression from selected histone promoters, suggesting that FUS is rather involved in regulation of core histone genes transcription. Thus, FUS bound to U7 snRNP can play a role in coupling between transcription and 3’end processing of replication dependant histone mRNAs.

The role of FUS in splicing regulation

Fused in sarcoma (FUS), also called translocated in liposarcoma (TLS), is a ubiquitously expressed DNA/RNA binding protein belonging to the TET family and predominantly localized in the nucleus. FUS is proposed to be involved in various RNA metabolic pathways including transcription regulation, nucleo-cytosolic RNA transport, microRNA processing or pre-mRNA splicing [1]. Mutations in the FUS gene were identified in patients with familial amyotrophic lateral sclerosis (ALS) type 6 and sporadic ALS [2, 3]. ALS, also termed Lou Gehrig's disease, is a fatal adult-onset neurodegenerative disease affecting upper and lower motor neurons in the brain and spinal cord. There is increasing evidence supporting the hypothesis that FUS might play an important role in pre-mRNA splicing regulation. Several splicing factors were identified to associate with FUS including hnRNPA2 and C1/C2 [4], Y-box binding protein 1 (YB-1) [5] and serine arginine (SR) proteins (SC35 and TASR) [6]. Additionally, FUS was identified as a constituent of human spliceosomal complexes [1]. Our recent results indicate that FUS has increased affinity for certain but not all snRNPs of the minor and major spliceosome. Furthermore, in vitro studies revealed that FUS directly interacts with a factor specific for one of those snRNPs. These findings might uncover the molecular mechanism by which FUS regulates splicing and could explain previously observed effects of FUS on the splicing of the adenovirus E1A minigene [7] and changes in splicing caused by ALS associated FUS mutations.
