Entry strategies into biosimilars: assessment of entry modes into the field of biosimilars from the perspective of pharmaceuticals, generics and biologics companies

Indústria farmacêutica de hoje está em transição. Como grandes blockbuster drogas estão perdendo ou estão prestes a perder a proteção de patente, e as grandes empresas farmacêuticas não estão substituindo os produtos com novas drogas químicas inovadoras, a indústria busca novas áreas de crescimento. Uma dessas áreas é o mercado de biossimilares, que está sendo inseridos por produtos farmacêuticos, genéricos e empresas de produtos biológicos. Mesmo que o grande potencial de mercado será acordado por volta de 2020, quando importantes blockbusters biológicos perder a proteção de patente, as empresas precisam decidir logo se querem participar ou não devido a elevadas barreiras à entrada técnicos, bem como de desenvolvimento de longo prazos. Como todas as empresas vêm de diferentes origens, compreendem capacidades diferentes e têm diferentes incentivos de entrada, a questão que surge é se esses fatos estão relacionados com as suas estratégias de entrada correspondentes. A tese utiliza estudos de caso de cada segmento da indústria farmacêutica - produtos farmacêuticos, biológicos e genéricos - e examina através de entrevistas semi-estruturadas, por isso que os participantes do estudo de caso entrevistados explicitamente escolhido sua estratégia de entrada. Os dados de entrevistas será então ligada a quadros estratégicos da revisão da literatura e irá ser utilizado para uma comparação global e análise. O estudo revelou que o fundo do participante do mercado que influenciam a sua estratégia de entrada. Os principais pontos de influência derivam tanto as barreiras à entrada, bem como os incentivos de entrada. A tese não é possível determinar o sucesso futuro do modo de entrada analisados no novo mercado.

The Methodological Influence of Peirce's Pragmatism on Knowledge Organization

Information and knowledge organization in Brazil has been historically influenced by theoretical linguistics. However, some aspects related to language theory and its interface with philosophy need to be further investigated, particularly the semiotic interpretation of information and knowledge organization processes. In order to advance a dialogue with the philosophy and semiotics of Charles Peirce (1839-1914), a theoretical and bibliographical study was carried out so as to understand and evaluate the contributions of the Peircean thought to information organization. It was found that several aspects of Peirce's work, viewed as a whole and not just semiotic concepts, suggest fundamental points to explain issues in information and knowledge organization. Basing on the analysis of Thellefsen's studies, this research presents some arguments aimed at reframing Peirce's pragmatism, which should no longer be mistakenly considered as a doctrine of practical results, but as a useful methodological approach for professionals dealing with knowledge organization in the field of Information Science.

Magnetic field of an in-plane vortex inside and outside a layered superconducting film

In the present work we study an anisotropic layered superconducting film of finite thickness. The film surfaces are considered parallel to the be face of the crystal. The vortex lines are oriented perpendicular to the film surfaces and parallel to the superconducting planes. We calculate the local field and the London free energy for this geometry. Our calculation is a generalization of previous works where the sample is taken as a semi-infinite superconductor. As an application of this theory we investigate the flux spreading at the super conducting surface.

Application of methylotrophic yeast Pichia pastoris in the field of food industry - A review

Since ancient times, the utilization of yeasts by the man has a great impact on the socio-economic development. After the advent of the technology of recombinant DNA, great advances have occurred due to the acquisition of strains of mutant yeasts in the field of applied research, and Saccharomyces cerevisiae has soon been outstanding as an interesting candidate for the expression of heterologous proteins of biotechnological interest. As the time goes by other alternative systems of expression have been shown because they have advantages over Saccharomyces cerevisiae. Among those new systems, Pichia pastoris is outstanding as methylotrophic yeast capable of growing in a culture medium containing methanol as the only source of carbon and energy. The induction of production of glycerol-3-phosphate dehydrogenase (GPD, NAD(+): oxido-redutase EC 1.1. 1.8) by Pichia pastoris was accomplished in the medium containing methanol. One of the most important key parameters in Pichia pastoris expression system is the methanol concentration. Bibliographic reviews on the Pichia pastoris production system have shown that the best culture conditions vary according to the strain used and/or kind of heterologous protein desired to be expressed. Therefore, we have sought to develop a system, involving expression of glycerol-3-phosphate dehydrogenase in the yeast Pichia pastoris, for generating sufficient quantities of the enzyme in order to asses its potential value for use in various food bioanalytical determination. Dehydrogenases have been widely used in the enzymatic assays of diverse composites of industrial interest, being enclosed among them glycerol and a number of important bioanalytical applications.

The magnetic field of a current carrying cosmic string

The magnetostatic field of an infinite rectilinear current placed in the stationary gravitational field of a rotating cosmic string is found. An interesting aspect of this problem is that although the metric is mathematically very simple, its physical meaning is not trivial. It depends only on topological parameters. So, the cosmic string vacuum space-time is locally equivalent to the Minkowski space-time, but not globally. The calculations are so simple that they can easily be shown in the classroom. © 1997 American Association of Physics Teachers.

The saturated magnetic field of the neutron stars

Considering the ferromagnetic screening for the decay of the X-ray neutron star magnetic field in the binary accretion phase, the phase transition of ferromagnetic materials in the crust of neutron star induces the ferromagnetic screening saturation of the accreted crust, which results in the minimum surface magnetic field of the accreting neutron star, about 108 G, if the accreted matter has completely replaced the crust mass of the neutron star. The magnetic field evolution versus accreted mass is given as Bs ∝ ΔM-0.9, and the obtained magnetic field versus spin period relation is consistent with the distribution of the binary X-ray sources and recycled pulsars. The further thermal effect on the magnetic evolution is also studied.

New insights for materials science characterisation using different complementary techniques combined with x-ray absorption spectroscopy

The combination of x-ray absorption spectroscopy (XAS) with UV-Vis and Raman spectroscopies or with Differential Scanning Calorimetry (DSC) has been recently carried out on the D44 beamline of DCI-LURE. The different set-ups used to perform such combinations are described and examples of combined investigations belonging to different field of materials science (coordination chemistry, sol-gel and catalysis) are presented. © Physica Scripta 2005.

Gravitational field of a straight cosmic string in the framework of higher-derivative gravity

The gravitational properties of a straight cosmic string are studied in the linear approximation of higher-derivative gravity. These properties are shown to be very different from those found using linearized Einstein gravity: there exists a short range gravitational (anti-gravitational) force in the nonrelativistic limit; in addition, the deflection angle of a light ray moving in a plane orthogonal to the string depends on the impact parameter. © 2008 World Scientific Publishing Company.

Relationship between psychological factors and symptoms of TMD in university undergraduate students.

Temporomandibular disorders is a collective term used to describe a number of related disorders involving the temporomandibular joints, masticatory muscles and occlusion with common symptoms such as pain, restricted movement, muscle tenderness and intermittent joint sounds. The multifactorial TMD etiology is related to emotional tension, occlusal interferences, tooth loss, postural deviation, masticatory muscular dysfunction, internal and external changes in TMJ structure and the various associations of these factors. The aim of this study was to evaluate the prevalence of the relationship between signs of psychological distress and temporomandibular disorder in university students. A total 150 volunteers participated in this study. They attended different courses in the field of human science at one public university and four private universities. TMD was assessed by the Research Diagnostic Criteria (RDC) questionnaire. Anxiety was measured by means of a self-evaluative questionnaire, Spielberger's Trait-State anxiety inventory, to evaluate students'state and trait anxiety. The results of the two questionnaires were compared to determine the relationship between anxiety levels and severity degrees of chronic TMD pain by means of the chi-square test. The significance level was set at 5%. The statistical analysis showed that the TMD degree has a positive association with state-anxiety (p = 0.008; p < 0.05) and negative with trait-anxiety (p = 0.619; p < 0.05). Moreover a high TMD rate was observed among the students (40%). This study concluded that there is a positive association between TMD and anxiety.
