New dopamine D2 receptor polymorphisms in rats and association with apomorphine-induced stereotypies.
2002
Adult Wistar rats injected with the dopamine receptor agonist apomorphine display different types of motility patterns with respect to oral stereotypes and locomotor activities. It was tested whether phenotypes exhibiting either ‘sniffing’ or ‘non-sniffing’ behaviour differed in gene structures of dopamine receptors D1 or D2. Forty-five Wistar rats of both genders were tested after a single dose of apomorphine (2 mg/kg s.c.) for stereotyped behaviour. Sequence analysis of the 5′ flanking region, the 5′ untranslated region and the coding region of the two genes revealed a new sequence for the 5′ flanking region of the D1 receptor gene and two polymorphisms in the promoter region of the D2 re…
Extracellular Domains of the Bradykinin B2 Receptor Involved in Ligand Binding and Agonist Sensing Defined by Anti-peptide Antibodies
1996
Many of the physiological functions of bradykinin are mediated via the B2 receptor. Little is known about binding sites for bradykinin on the receptor. Therefore, antisera against peptides derived from the putative extracellular domains of the B2 receptor were raised. The antibodies strongly reacted with their corresponding antigens and cross-reacted both with the denatured and the native B2 receptor. Affinity-purified antibodies to the various extracellular domains were used to probe the contact sites between the receptor and its agonist, bradykinin or its antagonist HOE140. Antibodies to extracellular domain 3 (second loop) efficiently interfered, in a concentration-dependent manner, with…
Endothelin receptors mediating contraction in goat cerebral arteries
1993
1. The aim of the present study was to identify the subtype of receptor mediating contraction to endothelin-1 and sarafotoxin S6b in goat isolated middle cerebral arteries. 2. Endothelin-1, endothelin-2 and endothelin-3 contracted cerebral arteries in a concentration-dependent manner. Although the three peptides were full agonists, the order of potency was endothelin-1 = endothelin-2 > endothelin-3, with a relative potency of endothelin-1 and endothelin-2 versus endothelin-3 of approximately 280. Sarafotoxin S6b induced concentration-dependent contractions with lower potency than endothelin-1/endothelin-2, higher potency than endothelin-3 and a higher maximum response than the three endothe…
Manejo de la hiperglucemia con fármacos no insulínicos en pacientes adultos con diabetes tipo 2
2019
Resumen: El adecuado tratamiento de la diabetes mellitus tipo 2 (DM2) incluye la alimentación saludable y el ejercicio (150 min/semana) como pilares básicos. Para el tratamiento farmacológico, la metformina es el fármaco de elección inicial, salvo contraindicación o intolerancia; en caso de mal control, se dispone de 8 familias terapéuticas (6 orales y 2 inyectables) como posibles combinaciones. Se presenta un algoritmo y unas recomendaciones para el tratamiento de la DM2. En prevención secundaria cardiovascular se recomienda asociar un inhibidor del cotransportador sodio-glucosa tipo 2 (iSGLT2) o un agonista del receptor de glucagon-like peptide-1 (arGLP1) en pacientes con obesidad. En pre…
Altered atypical coupling of γ-aminobutyrate type A receptor agonist and convulsant binding sites in subunit-deficient mouse lines
2001
We searched for subunit correlations for GABA(A) receptor-associated atypically GABA-insensitive [35S]TBPS binding. The homomeric beta3 subunit receptors could be excluded, as GABA-insensitive [35S]TBPS binding was present in beta3-/- mice. Localization of GABA-insensitive [35S]TBPS binding correlated best with those of delta, alpha4 and alpha6 subunit mRNAs. The amounts of GABA-insensitive [35S]TBPS binding components were increased in delta-/- mice, but dramatically reduced in alpha6-/- mice, suggesting a role for alpha6 but excluding delta subunits.
Personality Traits and Foreign Policy Attitudes in German Public Opinion
2007
This article examines the effects of personality traits on attitudes toward foreign policy issues among the German public. Building on previous research, it argues that personality characteristics shape an individual's motivation, goals, and values, thereby providing criteria to evaluate external stimuli and affecting foreign policy opinions. An analysis of survey data from a random sample of Germans eligible to vote confirms that the personality traits play a role in attitudes toward foreign policy issues. By and large, personality affects foreign policy opinions roughly as strongly as traditional factors such as partisanship, ideology, and social background. Among the traits studied, agr…
Examining the effects of birth order on personality.
2015
This study examined the long-standing question of whether a person’s position among siblings has a lasting impact on that person’s life course. Empirical research on the relation between birth order and intelligence has convincingly documented that performances on psychometric intelligence tests decline slightly from firstborns to laterborns. By contrast, the search for birth-order effects on personality has not yet resulted in conclusive findings. We used data from three large national panels from the United States (N = 5,240), Great Britain (N = 4,489), and Germany (N = 10,457) to resolve this open research question. This data base allowed us to identify even very small effects of birth o…
Can personality predict retirement behaviour? A longitudinal analysis combining survey and register data from Norway.
2017
Published version of an article in the journal: European Journal of Ageing. Also available from the publisher at: http://dx.doi.org/10.1007/s10433-011-0212-6 This study investigates how far personality can predict the timing and routes of people’s retirement. It uses a large comprehensive Norwegian survey, with larger sample size than earlier related studies, providing estimates of personality based on the five-factor model. The survey data are matched with administrative data, allowing observations of retirement over the 2002–2007 period. The analysis distinguishes between the disability and the non-disability retirements. Retirement is investigated using discrete time, competing risk, log…
Assessing the impact of agri-environmental schemes on the eco-efficiency of rain-fed agriculture
2012
This paper analyses the impact of the Agri-environmental Extensification Scheme for the Protection of Flora and Fauna (F&F Scheme) on the eco-efficiency of a sample of dryland farms in the Spanish region of Castile and Leon. Using Data Envelopment Analysis (DEA) and the so-called program decomposition approach to efficiency measurement, we explore whether or not the production technology of the farms included in the F&F Scheme is more eco-efficient than the technology used by farms that are not included in the Scheme. The re-sults obtained confirm the foregoing hypothesis, providing evidence that environmental pres-sures could be reduced if all farms adopted the F&F Scheme technology. Furth…
Earth system data cubes unravel global multivariate dynamics
2020
Understanding Earth system dynamics in light of ongoing human intervention and dependency remains a major scientific challenge. The unprecedented availability of data streams describing different facets of the Earth now offers fundamentally new avenues to address this quest. However, several practical hurdles, especially the lack of data interoperability, limit the joint potential of these data streams. Today, many initiatives within and beyond the Earth system sciences are exploring new approaches to overcome these hurdles and meet the growing interdisciplinary need for data-intensive research; using data cubes is one promising avenue. Here, we introduce the concept of Earth system data cu…
