Release of [3H]acetylcholine from the isolated rat or guinea-pig trachea evoked by preganglionic nerve stimulation; a comparison with transmural stim…
1991
Basal and stimulated outflow of radioactive acetylcholine, phosphorylcholine and choline from rat and guinea-pig isolated tracheae were measured by reverse phase HPLC followed by liquid-scintillation-spectrometry. Tracheae were stimulated either by an electrical field (transmural stimulation) or by a local stimulation of the innervating parasympathetic nerves (preganglionic stimulation). Epithelium was removed in most experiments, as the epithelium inhibits acetylcholine release. The basal tritium efflux (1,600 dpm/3min) from rat isolated tracheae incubated with [3H]choline consisted of 56% [3H]phosphorylcholine and 38% [3H]choline. Preganglionic stimulation (15 Hz, 1,200 pulses) caused a 2…
Über die Wirkung von Phosphodiesterase-Hemmstoffen am Herzen / The Influence of Phosphodiesterase Blocking Agents on the Perfused Guinea Pig Heart
1969
Es wurde der Einflus von Phosphodiesterase-Hemmstoffen auf die Funktion und einige Parameter des Kohlenhydratstoffwechsels des Herzens untersucht, um weiteren Aufschlus uber den Zusammenhang zwischen cyclischem AMP und der Regulation dieser Funktionen zu gewinnen. Isolierte Meerschweinchenherzen wurden nach Langendokff bei 37° C mit carbogengesattigter Tyrodelosung perfundiert und konstant mit einer Frequenz von 180/min gereizt. Die Herzen wurden nach einem Kontrollvorlauf 5–20 min mit der pharmakonhaltigen Tyrodelosung durchstromt. Es wurde die Wirkung von Substanzen untersucht, die nach Senft u. Mitarb. [1] in den angegebenen Konzentrationen eine 50% Hemmung der PDE des Rinderherzens in v…
Nationwide Analysis on Surgical Staging Procedures and Systemic Treatment for Patients With Endometrial Cancer in Germany
2012
ObjectiveIn 2009 and 2006, the Arbeitsgemeinschaft Gynäkologische Onkologie evaluated therapeutic approaches for endometrial carcinoma (EC) in Germany.Methods and MaterialsA questionnaire was developed and sent to 775 German gynecologic departments in 2009 (500 in 2006). The results of the questionnaires were compared with each other and with the recommendations of the Arbeitsgemeinschaft Gynäkologische Onkologie’s guideline. Subgroup analyses were performed, dividing the participating centers into small and large centers and into centers with less and more experience with EC.ResultsResponses were available in 33.3% in 2009 and 35.8% in 2006. Comparing 2009 with 2006, it became apparent tha…
Determinants of health policy impact: comparative results of a European policymaker study.
2003
This article will use a new theoretical framework for the analysis of health policy impact introduced by Rütten et al. (2003). In particular, it will report on a comparative European study of policymakers' perception and evaluation of specific determinants of the policy impact, both in terms of output (implemented measures) and outcome (health behaviour change). Policy determinants investigated are goals, resources, obligations and opportunities as related to the policymaking process.Theory is applied to a comparative analysis of prevention and health promotion policy in Belgium, Finland, Germany. The Netherlands, Spain and Switzerland. The study is MED2-part of a project that has developed…
Hereditary gastrointestinal cancers: ESMO Clinical Practice Guidelines for diagnosis, treatment and follow-up.
2019
Knowledge of genetic susceptibility to gastrointestinal cancers is constantly evolving with identification of new genes. Similarly, a better understanding of the genotype/phenotype relationship in patients with Lynch syndrome (LS) or familial adenomatous polyposis (FAP) is leading to more individualised surveillance recommendations. In addition, molecular profiling of patients with cancer has been shown to guide targeted therapies, such as immunotherapy. Specialists involved in the care of patients with gastrointestinal cancer should be familiar with the main hereditary cancer syndromes and refer patients to specialised cancer genetic units for adequate genetic counselling and to address sp…
The Lancet Psychiatry Commission: a blueprint for protecting physical health in people with mental illness.
2019
The poor physical health of people with mental illness is a multifaceted, transdiagnostic, and global problem. People with mental illness have an increased risk of physical disease, as well as reduced access to adequate health care. As a result, physical health disparities are observed across the entire spectrum of mental illnesses in low-income, middle-income, and high-income countries. The high rate of physical comorbidity, which often has poor clinical management, drastically reduces life expectancy for people with mental illness, and also increases the personal, social, and economic burden of mental illness across the lifespan. This Commission summarises advances in understanding on the…
Effects of lindane on fish carbohydrate metabolism.
1991
Exposure of the European eel (Anguilla anguilla) to a high sublethal concentration of 0.335 ppm (0.50 of the 96-hr LC50) of lindane for 6, 12, 24, 48, 72, and 96 hr affected carbohydrate metabolism. Muscle glycogen levels decreased significantly (P less than 0.05) at 6, 12, 24, 48, 72, and 96 hr; liver glycogen content did not decline at any time. Muscle glucose levels in fish were elevated at 6, 12, 24, 48, 72, and 96 hr but in liver, the levels increased only at 96 hr. Mean values of muscle and liver pyruvate were elevated significantly (P less than 0.05) at 6, 12, 24, 48, and 72 hr. Muscle lactate levels increased at 6, 12, 24, and 48 hr in pesticide-treated fish. Liver lactate levels we…
Recommendations of the Geriatric Cardiology Section of the Spanish Society of Cardiology for the Assessment of Frailty in Elderly Patients With Heart…
2018
Frailty is an age-associated clinical syndrome characterized by a decrease in physiological reserve in situations of stress, constituting a state of vulnerability that involves a higher risk of adverse events. Its prevalence in Spain is high, especially in elderly individuals with comorbidity and chronic diseases. In cardiovascular disease, frailty is associated worse clinical outcomes and higher morbidity and mortality in all scenarios, in both acute and chronic settings, and could consequently influence diagnosis and treatment. However, frailty is often not addressed or included when planning the management of elderly patients with heart disease. In this article, we review the available s…
Tetrodotoxin slightly shortens action potential duration in ventricular but not in atrial heart muscle.
1988
Tetrodotoxin (TTX), at concentrations significantly decreasing maximal upstroke velocity (dV/dtmax) of the action potential, exerted variable effects on action potential duration (APD) in different myocardial preparations. APD was virtually unchanged by tetrodotoxin in the guinea pig atrium, but slightly shortened in the guinea pig ventricle at maximally effective concentrations. In the human ventricle, both dV/dtmax and APD were reduced in the same concentration range of TTX. These results suggest that a TTX-sensitive sodium current significantly contributes to the repolarization phase of the action potential in ventricular but not in atrial heart muscle.

2014
Background Since the Atlanta Symposium several guidelines and consensus conferences have been published to improve the management and understanding of patients with acute pancreatitis. Herein, a review of the most recent guidelines on acute pancreatitis is carried out, trying to find differences and similarities.
