Direct visualization of the trimeric structure of the ASIC1a channel, using AFM imaging.

There has been confusion about the subunit stoichiometry of the degenerin family of ion channels. Recently, a crystal structure of acid-sensing ion channel (ASIC) 1a revealed that it assembles as a trimer. Here, we used atomic force microscopy (AFM) to image unprocessed ASIC1a bound to mica. We detected a mixture of subunit monomers, dimers and trimers. In some cases, triple-subunit clusters were clearly visible, confirming the trimeric structure of the channel, and indicating that the trimer sometimes disaggregated after adhesion to the mica surface. This AFM-based technique will now enable us to determine the subunit arrangement within heteromeric ASICs.

Direct and indirect root defences of milkweed (Asclepias syriaca): trophic cascades, trade-offs and novel methods for studying subterranean herbivory

P>1. Entomopathogenic nematodes can function as indirect defence for plants that are attacked by root herbivores. By releasing volatile organic compounds (VOCs), plants signal the presence of host insects and thereby attract nematodes.2. Nonetheless, how roots deploy indirect defences, how indirect defences relate to direct defences, and the ecological consequences of root defence allocation for herbivores and plant biomass are essentially unknown.3. We investigate a natural below-ground tritrophic system, involving common milkweed, a specialist root-boring beetle and entomopathogenic nematodes, and asked whether there is a negative genetic correlation between direct defences (root cardenolides) and indirect defences (emission of volatiles in the roots and nematode attraction), and between constitutive and inducible defences.4. Volatiles of roots were analysed using two distinct sampling methods. First, we collected emissions from living Asclepias syriaca roots by dynamic headspace sampling. This method showed that attacked A. syriaca plants emit five times higher levels of volatiles than control plants. Secondly, we used a solid phase micro-extraction (SPME) method to sample the full pool of volatiles in roots for genetic correlations of volatile biosynthesis.5. Field experiments showed that entomopathogenic nematodes prevent the loss of biomass to root herbivory. Additionally, suppression of root herbivores was mediated directly by cardenolides and indirectly by the attraction of nematodes. Genetic families of plants with high cardenolides benefited less from nematodes compared to low-cardenolide families, suggesting that direct and indirect defences may be redundant. Although constitutive and induced root defences traded off within each strategy (for both direct and indirect defence, cardenolides and VOCs, respectively), we found no trade-off between the two strategies.6. Synthesis. Constitutive expression and inducibility of defences may trade off because of resource limitation or because they are redundant. Direct and indirect defences do not trade off, likely because they may not share a limiting resource and because independently they may promote defence across the patchiness of herbivore attack and nematode presence in the field. Indeed, some redundancy in strategies may be necessary to increase effective defence, but for each strategy, an economy of deployment reduces overall costs.

Direct detection of a BRAF mutation in total RNA from melanoma cells using cantilever arrays.

Malignant melanoma, the deadliest form of skin cancer, is characterized by a predominant mutation in the BRAF gene. Drugs that target tumours carrying this mutation have recently entered the clinic. Accordingly, patients are routinely screened for mutations in this gene to determine whether they can benefit from this type of treatment. The current gold standard for mutation screening uses real-time polymerase chain reaction and sequencing methods. Here we show that an assay based on microcantilever arrays can detect the mutation nanomechanically without amplification in total RNA samples isolated from melanoma cells. The assay is based on a BRAF-specific oligonucleotide probe. We detected mutant BRAF at a concentration of 500 pM in a 50-fold excess of the wild-type sequence. The method was able to distinguish melanoma cells carrying the mutation from wild-type cells using as little as 20 ng µl(-1) of RNA material, without prior PCR amplification and use of labels.

Business Organization and Coordination in Marketing Specialty Hogs: A Comparative Analysis of Two Firms from Iowa, November 2005

We study business organization and coordination of specialty-market hog production using a comparative analysis of two Iowa pork niche-marketing firms. We describe and analyze each firms management of five key organizational challenges: planning and logistics, quality assurance, process verication and management of �credence attributes,� business structure, and profit sharing. Although each firm is engaged in essentially the same activity, there are substantial differences across the two firms in the way production and marketing are coordinated. These differences are partly explained by the relative size and age of each firm, thus highlighting the importance of organizational evolution in agricultural markets, but are also partly the result of a formal organizational separation between marketing and production activities in one of the firm.

Voiko totuutta tavoittaa? : direct cinema -tyylisuunnan käyttö dokumenttielokuvassa

The subject of this study is the use of direct cinema style in documentary film. The main purpose of this thesis was to the research the ways in which direct cinema style attempts to show and achieve truth in documentary films. The following questions were posed: Is it possible to depict reality in a documentary film; how does the choice of using this style affect the final documentary? The essential purpose of this study was to try to see whether the direct cinema style works when trying to achieve truth in a documentary film. This work consints of two elements, the theoretical part and the short documentary. The theoretical part deals with the history, the truth, and the direct cinema- style in documentaries. The theoretical information of direct cinema has been used when making the short documentary. In the documentary Tuloaula 2 I have studied the way in which using direct cinema -style works in practise. The documentary has followed as strictly as possible the direct cinema style. I was the director, the cameraman and the editor of my documentary film. In the documentary film Tuloaula 2 it appeared that the direct cinema style works best when filming everyday life. By using this style it is easy for the director to observe and leave his own persona in the background. The strength in using the direct cinema style is that it enables the viewer to build his/her own impression on the subject. Even though the direct cinema style aims to achieve objectivity the director has to make numerous subjective choices during both the filming and the editing process. These subjective choices automatically effect the "truth" of the documentary film. The difficulty in a direct cinema style is the large amount of material. This often leads to a long editing phase, which is not often possible in the busy production schedules. The direct cinema style is not at its best when shooting people who are passive because their attention often focuses too much on the camera. In general, the best way to make a documentary film would be to use many documentary styles in one film and not to srictly concentrate on only one style.

Estratègies de marketing per assolir l'èxit : llançament d'una revista per a joves

Actualment, en aquesta societat és difícil introduir un nou producte al mercat degut alshàbits de consum adquirits per la població. Per tal de superar aquests obstacles, el marketing actual s'ha tornat més complex i sofisticat. Per tot això, s’analitzaran els passos que s'han de seguir per tenir èxit a l'hora de llançar un nou producte.Per començar, s’enfocarà el tema en un únic producte, una revista dirigida a un públic entre 16 i 30 anys aproximadament. Així doncs, es suposarà una situació fictícia on una empresa independent, que està intentant introduir una nova publicació al mercat de la premsa escrita, contractarà un estudi de marketing per decidir els continguts de la revista, a quin tipus de consumidors estarà dirigida i analitzar els punts forts i febles de la competència per saber quina directriu hauria de seguir l’estratègia comercial.Seguidament, es decidirà la marca de la revista: el títol i el disseny del logotip. El preu òptim de llançament, els mitjans de comunicació que s’utilitzarien per donar a conèixer la revista, quins canals de distribució es seguirien i quins serien els punts de venda. Per tot això, es realitzaran enquestes i es faran diversos estudis sobre l’entorn general de l’empresa i la situació actual del sector.Amb tot això volem aconseguir el següent objectiu: ¿Quines estratègies de marketings'haurien de seguir per assolir l'èxit?

Collective Marketing Arrangements for Geographically Differentiated Agricultural Products: Welfare Impacts and Policy Implications, May 2006

This paper examines the incentive of atomistic agricultural producers within a specific geographical region to differentiate and collectively market products. We develop a model that allows us to analyze the market and welfare effects of the main types of real-world producer organizations, using it to derive economic insights regarding the circumstances under which these organizations will evolve, and describing implications of the results obtained in the context of an ongoing debate between the European Union and United States. As the anticipated fixed costs of development and marketing increase and the anticipated size of the market falls, it becomes essential to increase the ability of the producer organization to control supply in order to ensure the coverage of fixed costs. Whenever a collective organization allows a market (with a new product) to exist that otherwise would not have existed there is an increase in societal welfare. Counterintuitively, stronger property right protection for producer organizations may be welfare enhancing even after a differentiated product has been developed. The reason for this somewhat paradoxical result is that legislation aimed at curtailing the market power of producer organizations may induce large technological distortions.

Direct cost of connecting, maintaining and disconnecting patient-controlled analgesia pump

Quantitative research that aimed to identify the mean total cost (MTC) of connecting, maintaining and disconnecting patient-controlled analgesia pump (PCA) in the management of pain. The non-probabilistic sample corresponded to the observation of 81 procedures in 17 units of the Central Institute of the Clinics Hospital, Faculty of Medicine, University of Sao Paulo. We calculated the MTC multiplying by the time spent by nurses at a unit cost of direct labor, adding the cost of materials and medications/solutions. The MTC of connecting was R$ 107.91; maintenance R$ 110.55 and disconnecting R$ 4.94. The results found will subsidize discussions about the need to transfer money from the Unified Health System to hospitals units that perform this technique of analgesic therapy and it will contribute to the cost management aimed at making efficient and effective decision-making in the allocation of available resources.

Comunicação de Marketing na Formação da Imagem dos Destinos Turísticos: o caso de Cabo Verde

Segundo a Organização Mundial do Turismo (OMT), o turismo é a maior indústria do séc. XXI gerando anualmente milhares de milhões de dólares em divisas para a economia de inúmeros países. Por apresentar um conjunto de características muito específicas, o sucesso desta actividade é fortemente condicionado pela imagem que os turistas e potenciais turistas apresentam relativamente a um determinado destino. Apesar de existirem muitos factores que interferem na formação desta imagem, a comunicação de marketing é apontada, pelos investigadores, como um dos elementos que desempenha um papel crucial neste âmbito. O objecto do presente trabalho de investigação é a comunicação de marketing na formação da imagem dos destinos turísticos particularizando o arquipélago de Cabo Verde. O principal objectivo da pesquisa, é analisar a eficácia da comunicação de marketing de três organizações (Cabo Verde – Investimentos, União Nacional dos Operadores Turísticos e operador Soltropico), na promoção do arquipélago de Cabo Verde, enquanto destino turístico, no mercado português. Para a realização deste estudo empírico, foram definidas três hipóteses. Essas hipóteses foram testadas através do cruzamento da informação proveniente de uma entrevista realizada aos directores de marketing de cada uma das três organizações, com os dados obtidos a partir da análise de conteúdo dos instrumentos de comunicação que têm vindo a ser utilizados pelas respectivas entidades para promover o destino e com as respostas de um conjunto de 115 turistas portugueses, a um questionário cujo assunto se encontra relacionado com os principais atributos de Cabo Verde enquanto destino de férias. A investigação realizada permitiu verificar que, de uma forma geral, existe uma sintonia entre os atributos de Cabo Verde que as organizações têm intenção de divulgar, os atributos deste destino que são transmitidos pelos seus instrumentos comunicação e os principais atributos do arquipélago indicados pelos turistas portugueses. Contudo, os resultados do estudo revelam também a necessidade de se introduzir algumas correcções a nível de conteúdos e imagens que se encontram presentes nos instrumentos de comunicação de algumas das organizações, visando a criação de uma imagem mais atractiva deste destino.

A non-randomized direct comparison of cognitive-behavioral short- and long-term treatment for binge eating disorder

Background: To compare treatment outcomes of a cognitive-behavioral long-term (CBT-L) and short-term (CBT-S) treatment for binge eating disorder (BED) in a non-randomized comparison and to identify moderators of treatment outcome. Methods: 76 female patients with BED participated in the study: 40 in CBT-L and 36 in CBT-S. Outcome values were compared at the end of the active treatment phase (16 sessions for CBT-L, 8 sessions for CBT-S) and at 12-month follow-up. Results: Both treatments produced significant reductions in binge eating. At the end of active treatment, but not at the end of follow-up, effects of primary outcomes (e.g. remission from binge eating, EDE shape concern) were better for CBT-L than for CBT-S. Dropout rates were significantly higher in CBT-L (35%) than in CBT-S (14%). Moderator analyses revealed that treatment efficacy for rapid responders and individuals exhibiting high scores on the mixed dietary negative affect subtype differed between the CBT-L and CBT-S with respect to objective binges, restraint eating and eating concern. Conclusion: Findings suggest that CBT in general represents an effective treatment for BED, but that subgroups of patients might profit more from a prolonged treatment. Short, lessintensive CBT treatments could nevertheless be a viable option in the treatment of BED.
