Gastronomy and Wine in the Alentejo Portuguese Region: Motivation and Satisfaction of Turists from Évora

Food and winemaking are a recognized tangible and intangible culturalheritage of Portugal. From the relationshipbetween these twocomponents, astrategic product emerged with a considerable potential for tourism industry, which is notignored bymany of tourism organizations. This chapter intends to analyze food and winemaking from atourism demand perspective. Particularly, this study describes visitors’ profi le, including, their motivations, their knowledgeabout theenological and gastronomicresourcesand the degreeof satisfaction. A total of 308 questionnaires were collected between February and May of 2012, from the visitors that visited the historic center of Évora (Alentejo-Portugal). Results reveal a visitor profi le associated with regional cuisine and wine products from Portugal. Moreover, visitors’ evidenced a high level of knowledge regarding the Portuguese cuisine and regional wines; although this not matches with their primary motivation for visit the city of Évora

Background and Objective: The anti-oestrogen tamoxifen requires metabolic activation to endoxifen by cytochr

The Risk of QTc-Interval Prolongation in Breast Cancer Patients Treated with Tamoxifen in Combination with Serotonin Reuptake Inhibitors

Purpose: Antidepressants like the serotonin reuptake inhibitors (SRIs) are often used concomitantly with tamoxifen (e.g. for treatment of depression). This may lead to an additional prolongation of the QTc-interval, with an increased risk of cardiac side effects. Therefore we investigated whether there is a drug-drug interaction between tamoxifen and SRIs resulting in a prolonged QTc-interval. Methods: Electrocardiograms (ECGs) of 100 patients were collected at steady state tamoxifen treatment, with or without concomitant SRI co-medication. QTc-interval was manually measured and calculated using the Fridericia formula. Primary outcome was difference in QTc-interval between tamoxifen monotherapy and tamoxifen concomitantly with an SRI. Results: The mean QTc-interval was 12.4 ms longer when tamoxifen was given concomitantly with an SRI (95% CI:1.8–23.1 ms; P = 0.023). Prolongation of the QTc-interval was particularly pronounced for paroxetine (17.2 ms; 95%CI:1.4–33.0 ms; P = 0.04), escitalopram (12.5 ms; 95%CI:4.4–20.6 ms; P 500 ms. Conclusions: Concomitant use of tamoxifen and SRIs resulted in a significantly higher mean QTc-interval, which was especially the case for paroxetine, escitalopram and citalopram. When concomitant administration with an SRI is warranted venlafaxine is preferred

Forensic pregnancy diagnostics with placental mRNA markers

Current methods for pregnancy diagnostics are based on immunodetection of pregnancy-specific proteins and in a forensic context suffer from sensitivity and specificity issues. Here, we applied reverse transcriptase polymerase chain reaction (RT-PCR) technology to 11 genes previously reported with placental mRNA circulating in maternal blood. We found two genes, hPL and βhCG, with pregnancy-specific expression in whole blood samples. RT-PCR detection of hPL was positive in all samples tested throughout the pregnancy, whereas βhCG was detectable until half of the second trimester but not at later gestation ages. For hPL, in vitro stability of the transcript was demonstrated until 2 months of age, and the hPL-specific RT-PCR assay applied was highly sensitive with reliable detection from down to 0.25 cm2 dried bloodstain. We therefore suggest hPL-specific RT-PCR as a new molecular tool for forensic pregnancy diagnostics from dried blood stains. Moreover, our results indicate that the time-wise reverse expression of hPL and βhCG during pregnancy may allow an RT-PCR-based estimation of the gestational age from blood stains, adding to the value of forensic pregnancy diagnosis for crime scene investigations

DHPR activation underlies SR Ca2+ release induced by osmotic stress in isolated rat skeletal muscle fibers

Changes in skeletal muscle volume induce localized sarcoplasmic reticulum (SR) Ca2+ release (LCR) events, which are sustained for many minutes, suggesting a possible signaling role in plasticity or pathology. However, the mechanism by which cell volume influences SR Ca2+ release is uncertain. In the present study, rat flexor digitorum brevis fibers were superfused with isoosmotic Tyrode's solution before exposure to either hyperosmotic (404 mOsm) or hypoosmotic (254 mOsm) solutions, and the effects on cell volume, membrane potential (Em), and intracellular Ca2+ ([Ca2+]i) were determined. To allow comparison with previous studies, solutions were made hyperosmotic by the addition of sugars or divalent cations, or they were made hypoosmotic by reducing [NaCl]o. All hyperosmotic solutions induced a sustained decrease in cell volume, which was accompanied by membrane depolarization (by 14–18 mV; n = 40) and SR Ca2+ release. However, sugar solutions caused a global increase in [Ca2+]i, whereas solutions made hyperosmotic by the addition of divalent cations only induced LCR. Decreasing osmolarity induced an increase in cell volume and a negative shift in Em (by 15.04 ± 1.85 mV; n = 8), whereas [Ca2+]i was unaffected. However, on return to the isoosmotic solution, restoration of cell volume and Em was associated with LCR. Both global and localized SR Ca2+ release were abolished by the dihydropyridine receptor inhibitor nifedipine by sustained depolarization of the sarcolemmal or by the addition of the ryanodine receptor 1 inhibitor tetracaine. Inhibitors of the Na-K-2Cl (NKCC) cotransporter markedly inhibited the depolarization associated with hyperosmotic shrinkage and the associated SR Ca2+ release. These findings suggest (1) that the depolarization that accompanies a decrease in cell volume is the primary event leading to SR Ca2+ release, and (2) that volume-dependent regulation of the NKCC cotransporter contributes to the observed changes in Em. The differing effects of the osmotic agents can be explained by the screening of fixed charges by divalent ions

Glycosylation defects underlying fetal alcohol spectrum disorder: a novel pathogenetic model: “When the wine goes in, strange things come out” – S.T. Coleridge, The Piccolomini

Fetal alcohol spectrum disorder (FASD) is an umbrella term used to describe the craniofacial dysmorphic features, malformations, and disturbances in growth, neurodevelopment and behavior occurring in individuals prenatally exposed to alcohol. Fetal alcohol syndrome (FAS) represents the severe end of this spectrum. Many pathophysiological mechanisms have hitherto been proposed to account for the disrupted growth and morphogenesis seen in FAS. These include impaired cholesterol-modification of the Sonic hedgehog morphogen, retinoic acid deficiency, lipoperoxidative damage due to alcohol-induced reactive oxygen species combined with reduced antioxidant defences, and malfunctioning cell adhesion molecules. In this report, we propose a completely novel concept regarding the pathogenesis of FAS. Based on our observation that transferrin isoelectric focusing (TIEF) – the most widely used screening tool for congenital disorders of glycosylation (CDG) – was transiently abnormal in a newborn with FAS and a confirmed maternal history of gestational alcohol abuse, we came to believe that FAS exemplifies a congenital disorder of glycosylation secondary to alcohol-inflicted disruption of (N-linked) protein glycosylation. Various pieces of evidence were found in the literature to substantiate this hypothesis. This observation implies, among others, that one might need to consider the possibility of maternal alcohol consumption in newborns with transient glycosylation abnormalities. We also present an integrated pathophysiological model of FAS, which incorporates all existing theories mentioned above as well as our novel concept. This model highlights the pivotal role of disrupted isoprenoid metabolism in the origination of FAS

Smart technologies for personalized experiences: a case study in the hospitality domain

Recent advances in the field of technology have led to the emergence of innovative technological smart solutions providing unprecedented opportunities for application in the tourism and hospitality industry.With intensified competition in the tourism market place, it has become paramount for businesses to explore the potential of technologies, not only to optimize existing processes but facilitate the creation of more meaningful and personalized services and experiences. This study aims to bridge the current knowledge gap between smart technologies and experience personalization to understand how smart mobile technologies can facilitate personalized experiences in the context of the hospitality industry. By adopting a qualitative case study approach, this paper makes a two-fold contribution; it a) identifies the requirements of smart technologies for experience creation, including information aggregation, ubiquitous mobile connectedness and real time synchronization and b) highlights how smart technology integration can lead to two distinct levels of personalized tourism experiences. The paper concludes with the development of a model depicting the dynamic process of experience personalization and a discussion of the strategic implications for tourism and hospitality management and research

‘Placing’ Space: exploring the socio-spatial impacts of cosmopolitan place-marketing approaches on British migrants in Spain

This article explores the sociospatial underpinnings of cosmopolitan place-marketing narratives and their impacts on British migrants living in Sitges, an affluent tourist town in Spain. Sitges’ place-marketing suggests that moving there automatically fosters a cosmopolitan identity. For British migrants in Sitges, this was understood to be exemplified through integration into the local community. Yet the vast majority found such integration impossible, not least because this conceptualization of cosmopolitanism overlooked the subjectivity of locals themselves, by whom they were most often rejected. It is argued that this mismatch between British migrants’ experiences and Sitges’ cosmopolitan place-marketing occurs because it relies on an understanding of subjective identity as generated locationally, enacted via movement to a specific “type” of place that incorporates particular understandings of space, place, and culture in relation to that identity. This overrides the necessity of relationality, undermining the ideal of reflexive identity-making on which cosmopolitan place-marketing narratives rely

Exercise capacity in children with isolated congenital complete atrioventricular block: does pacing make a difference?

Item does not contain fulltextThe management of patients with isolated congenital complete atrioventricular block (CCAVB) has changed during the last decades. The current policy is to pace the majority of patients based on a variety of criteria, among which is limited exercise capacity. Data regarding exercise capacity in this population stems from previous publications reporting small case series of unpaced patients. Therefore, we have investigated the exercise capacity of a group of contemporary children with CCAVB. Sixteen children (mean age 11.5 +/- 4; seven boys, nine girls) with CCAVB were tested. In 13 patients, a median number of three pacemakers were implanted, whereas in three patients no pacemaker was given. All patients had an echocardiogram and completed a cardiopulmonary cycle exercise test. Exercise parameters were determined and compared with reference values obtained from healthy Dutch peers. The peak oxygen uptake/body mass was reduced to 34.4 +/- 9.5 ml kg(-1) min(-1) (79 +/- 24% of predicted) and the ventilatory threshold was reduced to 52 +/- 17% of peak oxygen uptake (78 +/- 21% of predicted), whereas the peak work load/body mass was 2.8 +/- 0.6 W/kg (91 +/- 24% of predicted), which was similar to controls. Importantly, 25% of the paced patients showed upper rate restriction by the pacemaker. In conclusion, children with CCAVB show a reduced peak oxygen uptake and ventilatory threshold, whereas they show normal peak work rates. This indicates that they generate more energy during exercise from anaerobic energy sources. Paced children with CCAVB do not perform better than unpaced children.1 april 201
