Pfefferland. Geschichten aus der Welt der Gewürze

Gewürze sind faszinierend: Sie haben Geschmack, Duft, Heilkraft und kosmetische Wirkung. Doch damit nicht genug. Gewürze sind Symbole für historische, kulturelle und soziale Klassifizierungen. Dieses Buch trägt allen Dimensionen Rechnung: Es nähert sich den Gewürzen zugleich sinnlich und wissenschaftlich. Die Autoren und Autorinnen, alle Ethnologen, folgen darum in ihren Essays vergnügt und augenzwinkernd einem ganz persönlichen Zugang zu Absinth und Rosmarin, Oregano, Gelbwurz und Petersilie. Immer aber vermitteln die Autoren auch Wissenswertes über die Herkunft, die Eigenschaften und die kulturelle Bedeutung der Gewürze. Der guten Küche verpflichtet, endet jeder Beitrag mit einem oder mehreren Rezepten, in denen das vorgestellten Gewürz eine besondere Rolle spielt.

Influence of transrectal and transabdominal ultrasound examination on salivary cortisol, heart rate, and heart rate variability in mares

Pregnancy diagnostics in equine reproduction are routinely performed using transrectal ultrasonography, although it is also possible to visualize the fetus by transabdominal ultrasound examinations from the 90th day of gestation onward. We hypothesized that ultrasound examinations may stress the mare and that the gestational stage status and lactation may influence the mare's stress reaction. To investigate the stress reaction, 25 thoroughbred mares of different age, pregnancy and lactational status underwent a transrectal examination. In pregnant mares, an additional transabdominal examination was performed. Salivary cortisol concentration, mean heart rate, and heart rate variability of mares were assessed to evaluate the reactions of hypothalamic–pituitary–adrenal (HPA) axis and of the autonomic nervous system. Significant differences were observed between lactating and nonlactating mares; with a lower responsiveness to stress in lactating mares. The transrectal ultrasound examination in nonlactating mares induced a significant increase in salivary cortisol (P < 0.05), and in the heart rate variability parameter, ratio of low to high frequencies (P < 0.05). This reflects an activation of the HPA axis and a shift to more sympathetic dominance. In contrast, a transabdominally performed pregnancy check did not induce an activation of the HPA axis over basal level but increased the mean heart rate and low to high frequency ratio. The results of this study indicate that checks of advanced pregnancies can be easily performed by transabdominal ultrasonography. With regard to animal welfare, this technique should be preferred during midgestation in nonlactating mares.

Current management options for liposarcoma and challenges for the future

Liposarcoma (LS) represents one of the most common soft tissue sarcomas. There are three major subtypes, namely, well/dedifferentiated, myxoid/round cell and pleomorphic LS. In general, LS is known to be a relatively chemo-resistant sarcoma subtype with the exception of the myxoid variant. Conventional chemotherapy with doxorubicin and ifosfamide represents the mainstay of systemic treatment in the first line. Other active cytotoxic agents include gemcitabine and docetaxel and the marine-derived compounds trabectedin. Recent progress in molecular diagnostics of each single LS subtype has improved the knowledge of the molecular characteristics and has led to two recent treatment targets: the amplification of mouse double minute 2 homolog and cyclin-dependent kinase-4 in well- and dedifferentiated LS. Thus far, only early-phase trials are reported and no new drugs have been introduced in daily clinical practice. The focus of this review is on current systemic treatment options, including novel strategies.

Combination of expression levels of miR-21 and miR-126 is associated with cancer-specific survival in clear-cell renal cell carcinoma

BACKGROUND Renal cell carcinoma (RCC) is marked by high mortality rate. To date, no robust risk stratification by clinical or molecular prognosticators of cancer-specific survival (CSS) has been established for early stages. Transcriptional profiling of small non-coding RNA gene products (miRNAs) seems promising for prognostic stratification. The expression of miR-21 and miR-126 was analysed in a large cohort of RCC patients; a combined risk score (CRS)-model was constructed based on expression levels of both miRNAs. METHODS Expression of miR-21 and miR-126 was evaluated by qRT-PCR in tumour and adjacent non-neoplastic tissue in n = 139 clear cell RCC patients. Relation of miR-21 and miR-126 expression with various clinical parameters was assessed. Parameters were analysed by uni- and multivariate COX regression. A factor derived from the z-score resulting from the COX model was determined for both miRs separately and a combined risk score (CRS) was calculated multiplying the relative expression of miR-21 and miR-126 by this factor. The best fitting COX model was selected by relative goodness-of-fit with the Akaike information criterion (AIC). RESULTS RCC with and without miR-21 up- and miR-126 downregulation differed significantly in synchronous metastatic status and CSS. Upregulation of miR-21 and downregulation of miR-126 were independently prognostic. A combined risk score (CRS) based on the expression of both miRs showed high sensitivity and specificity in predicting CSS and prediction was independent from any other clinico-pathological parameter. Association of CRS with CSS was successfully validated in a testing cohort containing patients with high and low risk for progressive disease. CONCLUSIONS A combined expression level of miR-21 and miR-126 accurately predicted CSS in two independent RCC cohorts and seems feasible for clinical application in assessing prognosis.

Relationship between the objectively-assessed neighborhood area and activity behavior in Swiss youth

Background Neighborhood attributes are modifiable determinants of physical activity (PA) and sedentary behavior (SB). We tested whether the objectively-assessed built and social environment was associated with PA and SB in Swiss youth and whether sex, age and the socioeconomic position (Swiss-SEP) modified such associations. Methods We combined data of 1742 youth (ages 4 to 17) from seven studies conducted within Switzerland between 2005–2010. All youth provided accelerometer data and a home address, which was linked to objective environmental data and the Swiss-SEP-index. Associations between neighborhood attributes and PA were analyzed by multivariable multilevel regression analyses. Results The extent of green areas and building density was positively associated with PA in the total sample (p < 0.05). Factors representing centrally located areas, and more schoolchildren living nearby tended to increase PA in secondary schoolchildren, boys and those from lower-ranked socioeconomic areas. In primary schoolchildren, the extent of green areas was positively associated with PA (p = 0.05). Associations between neighborhood attributes and PA were more pronounced in youth from low socioeconomic areas. Conclusions The results indicate that some associations between neighborhood attributes and PA differ by age, sex and socioeconomic area. This should be taken into account when planning interventions to increase childhood PA.

Regional differences of physical activity and sedentary behaviour in Swiss children are not explained by socio-demographics or the built environment

Objective We evaluated whether regional differences in physical activity (PA) and sedentary behaviour (SB) existed along language boundaries within Switzerland and whether potential differences would be explained by socio-demographics or environmental characteristics. Methods We combined data of 611 children aged 4 to 7 years from four regional studies. PA and SB were assessed by accelerometers. Information about the socio-demographic background was obtained by questionnaires. Objective neighbourhood attributes could be linked to home addresses. Multivariate regression models were used to test associations between PA and SB and socio-demographic characteristics and neighbourhood attributes. Results Children from the German compared to the French-speaking region were more physically active and less sedentary (by 10–15 %, p < 0.01). Although German-speaking children lived in a more favourable environment and a higher socioeconomic neighbourhood (differences p < 0.001), these characteristics did not explain the differences in PA behaviour between French and German speaking. Conclusions Factors related to the language region, which might be culturally rooted were among the strongest correlates of PA and SB among Swiss children, independent of individual, social and environmental factors.

Reactivity to Accelerometer Measurement of Children and Adolescents

PURPOSE: Awareness of being monitored can influence participants' habitual physical activity (PA) behavior. This reactivity effect may threaten the validity of PA assessment. Reports on reactivity when measuring the PA of children and adolescents have been inconsistent. The aim of this study was to investigate whether PA outcomes measured by accelerometer devices differ from measurement day to measurement day and whether the day of the week and the day on which measurement started influence these differences. METHODS: Accelerometer data (counts per minute [cpm]) of children and adolescents (n = 2081) pooled from eight studies in Switzerland with at least 10 h of daily valid recording were investigated for effects of measurement day, day of the week, and start day using mixed linear regression. RESULTS: The first measurement day was the most active day. Counts per minute were significantly higher than on the second to the sixth day, but not on the seventh day. Differences in the age-adjusted means between the first and consecutive days ranged from 23 to 45 cpm (3.6%-7.1%). In preschoolchildren, the differences almost reached 10%. The start day significantly influenced PA outcome measures. CONCLUSIONS: Reactivity to accelerometer measurement of PA is likely to be present to an extent of approximately 5% on the first day and may introduce a relevant bias to accelerometer-based studies. In preschoolchildren, the effects are larger than those in elementary and secondary schoolchildren. As the day of the week and the start day significantly influence PA estimates, researchers should plan for at least one familiarization day in school-age children and randomly assign start days.

Mögliche Auswirkungen eines Handels- und Investitionsschutzabkommens EU-USA auf die Schweiz

Die gegenwärtigen Bemühungen für ein umfassendes Handels- und Investitionsschutzabkommen zwischen der EU und den USA werden nicht ohne Auswirkungen auf die Schweiz bleiben. Eine Studie des World Trade Institute der Universität Bern im Auftrag des Staatssekretariats für Wirtschaft analysiert die möglichen Auswirkungen eines Abkommens auf die Schweizer Wirtschaft und auf die Handelsbeziehungen der Schweiz. Unterschiedliche Szenarien führen dabei zu unterschiedlichen Auswirkungen.

BRCA2-Deficient Sarcomatoid Mammary Tumors Exhibit Multidrug Resistance.

Pan- or multidrug resistance is a central problem in clinical oncology. Here, we use a genetically engineered mouse model of BRCA2-associated hereditary breast cancer to study drug resistance to several types of chemotherapy and PARP inhibition. We found that multidrug resistance was strongly associated with an EMT-like sarcomatoid phenotype and high expression of the Abcb1b gene, which encodes the drug efflux transporter P-glycoprotein. Inhibition of P-glycoprotein could partly resensitize sarcomatoid tumors to the PARP inhibitor olaparib, docetaxel, and doxorubicin. We propose that multidrug resistance is a multifactorial process and that mouse models are useful to unravel this. Cancer Res; 75(4); 732-41. ©2014 AACR.

Zum Freihandelsabkommen EU-USA: Auswirkungen auf die Schweiz

Seit Juli 2013 laufen die Verhandlungen über ein umfassendes Freihandels- und Investitionsschutzabkommen zwischen der EU und den USA. Die Verhandlungen laufen noch, und es ist zum heutigen Zeitpunkt wenig bekannt zum Ausgang und Umfang des Abkommens. Zwei der in der Öffentlichkeit breit diskutierten Streitpunkte sind das geplante Investor-Staat-Streitbeilegungsverfahren, sowie die sogenannten Chlor-Hühnchen. Das geplante Abkommen soll aber weit darüber hinaus greifen und nebst dem Zollabbau für Industrie- und Agrarprodukte auch die Beseitigung von nicht-tarifären Handelshemmnissen umfassen. Nicht-tarifäre Handelshemmnisse werden typischerweise durch eine Rechtsharmonisierung im Bereich der Produktionsstandards reduziert. Eine solche Harmonisierung könnte sich für die Schweizer Industrie als Herausforderung herausstellen. Auch strikte Ursprungsregeln könnten sich auf einzelne Schweizer Zwischenprodukte negativ auswirken. Potenziell negative Auswirkungen könnten aber durch verschiedene handelspolitische Massnahmen gemindert werden. Soweit minilaterale Abkommen wie das TTIP-Abkommen eine nicht-diskriminierende Rechtsharmonisierung vorsehen, wirken sie sich insgesamt primär positiv und wachstumsfördernd für Drittstaaten wie die Schweiz aus.
