Will biological agents supplant systemic glucocorticoids as the first-line treatment for thyroid-associated ophthalmopathy?
No full textIn this article, the two authors present their opposing points of view concerning the likelihood that glucocorticoids will be replaced by newly developed biological agents in the treatment of active, moderate-to-severe thyroid-associated ophthalmopathy (TAO). TAO is a vexing, disfiguring and potentially blinding autoimmune manifestation of thyroid autoimmunity. One author expresses the opinion that steroids are nonspecific, frequently fail to improve the disease and can cause sometimes serious side effects. He suggests that glucocorticoids should be replaced as soon as possible by more specific and safer drugs, once they become available. The most promising of these are biological agents. The other author argues that glucocorticoids are proven effective and are unlikely to be replaced by biologicals. He reasons that while they may not uniformly result in optimal benefit, they have been proven effective in many reports. He remains open minded about alternative therapies such as biologicals but remains skeptical that they will replace steroids as the first-line therapy for active, moderate-to-severe TAO without head-to-head comparative clinical trials demonstrating superiority. Despite these very different points of view, both authors are optimistic about the availability of improved medical therapies for TAO, either as single agents or in combination. Further, both agree that better treatment options are needed to improve the care of our patients with active moderate-to-severe TAO

Axisymmetric polydimethysiloxane microchannels for in vitro hemodynamic studies
No full textThe current microdevices used for biomedical research are often manufactured using microelectromechanical systems (MEMS) technology. Although it is possible to fabricate precise and reproducible rectangular microchannels using soft lithography techniques, this kind of geometry may not reflect the actual physiology of the microcirculation. Here, we present a simple method to fabricate circular polydimethysiloxane (PDMS) microchannels aiming to mimic an in vivo microvascular environment and suitable for state-of-the-art microscale flow visualization techniques, such as confocal µPIV/PTV. By using a confocal µPTV system individual red blood cells (RBCs) were successfully tracked trough a 75 µm circular PDMS microchannel. The results show that RBC lateral dispersion increases with the volume fraction of RBCs in the solution, i.e. with the hematocrit

Metabolic profiling and population screening of analgesic usage in nuclear magnetic resonance spectroscopy-based large-scale epidemiologic studies
No full textThe application of a 1H nuclear magnetic resonance (NMR) spectroscopy-based screening method for determining the use of two widely available analgesics (acetaminophen and ibuprofen) in epidemiologic studies has been investigated. We used samples and data from the cross-sectional INTERMAP Study involving participants from Japan (n = 1145), China (n = 839), U.K. (n = 501), and the U.S. (n = 2195). An orthogonal projection to latent structures discriminant analysis (OPLS-DA) algorithm with an incorporated Monte Carlo resampling function was applied to the NMR data set to determine which spectra contained analgesic metabolites. OPLS-DA preprocessing parameters (normalization, bin width, scaling, and input parameters) were assessed systematically to identify an optimal acetaminophen prediction model. Subsets of INTERMAP spectra were examined to verify and validate the presence/absence of acetaminophen/ibuprofen based on known chemical shift and coupling patterns. The optimized and validated acetaminophen model correctly predicted 98.2%, and the ibuprofen model correctly predicted 99.0% of the urine specimens containing these drug metabolites. The acetaminophen and ibuprofen models were subsequently used to predict the presence/absence of these drug metabolites for the remaining INTERMAP specimens. The acetaminophen model identified 415 out of 8436 spectra as containing acetaminophen metabolite signals while the ibuprofen model identified 245 out of 8604 spectra as containing ibuprofen metabolite signals from the global data set after excluding samples used to construct the prediction models. The NMR-based metabolic screening strategy provides a new objective approach for evaluation of self-reported medication data and is extendable to other aspects of population xenometabolome profiling
Values as reasons for consumer decisions – an inter-cultural comparison
No full textNowadays, consumers usually do not just consider the functional use of a product. At least equally important are the emotional experiences that are tied up with the product and that are sated with non-material elements of a product. Which non-material elements of a product are considered important by the consumer, depends on his or her personal values. Therefore, the identification of personal values assists in explaining the consumers’ purchasing motives. Since personal values do not just influence a consumers’ purchasing decision but vary between cultural circles, it is expected that cultural values lead to culture-specific consumption patterns. To analyse the coherences between cultural values and the consumer behaviour of a cultural circle, 40 female wine consumers, comprised of 20 German and 20 Ukrainian women, were interviewed on the basis of Means-End-Chain-Theory using laddering-interviews. The initial findings of this qualitative survey will be presented in this poster.Means-End-Chain-Theory, cross-cultural comparison, wine consumers, Consumer/Household Economics,

El "añadido" castellano del TJ 1 o las mal llamadas "prosiflcaciones"
No full textThe author suggests to give the name of "addition" to the first twenty-five Cantigas de Santa María, written in prose, of the Ms TJ l. The author thinks that these additions do not come neither from Alfonso X nor from his surrouindings. They should have been added when the cultural reader was different and did not know the language of Galice. What proves this is the fact that the person who wrote this "addition" obtained information from another sources in some miracles (numbers 2 and 3) and those of praise are a theological gloss.El autor propone que se llame "añadido" a las hasta ahora denominadas prosificaciones castellans de las primeras veinticinco cantigas de Santa María del Ms TJ l. Él entiende que no se deben a Alfonso X, ni a su entorno. Que debieren ser añadidas en un tiempo en que el lector cultural era distinto y desconocía el gallego. Esto lo demuestra en cuanto el responsable del tal "añadido" acude a fuentes distintas en algunos milagros (números 2 y 3) y las de loor son una glosa teológica
