The image of the smoking and non-smoking young person
1985
MORE than 1,600 Finnish secondary school pupils between the ages of 12 and 16 completed a question naire about their image of the smoking and non- smoking adolescent. A smoker was described as nervous, unfriendly, untidy, stupid and a low achiever in sport and academic work, but despite this, was seen as a leader. Non-smokers were seen as calm, strong, fairly modest, friendly, tidy and smart, but not as leaders. Older pupils saw the smoker in a more positive light. Those who smoked saw the non- smoker image as positive, and rated the smoking image more highly than did non smokers.
Blood CO2 and pH Transients During Apnoea after O2 Breathing in Patients
1990
Endotracheal intubation always is combined with an apnoea the duration of which is dependent on the technique used, the skills of the intubator, and the anatomical situation. The resulting typical potential risks may be (among others) both hypoxaemia and hypercapnia. Therefore the tolerable apnoea time for an intubation procedure is limited in clinical practice to 1 – 2 minutes. It must be noted that the developing hypercapnia is inevitable, whereas hypoxaemia may be avoided even in prolonged apnoea (e.g. >2 min) with “adaequate” preoxygenation [Duda et al., 1988]. Using de-nitrogenation techniques (breathing pure oxygen for 30 to 60 min) “anaesthetized and curarized normal subjects tolerat…
Was heißt wie? Ansatz und Glossar zu Befundung und Verständnis in der HRCT der Lunge
1996
In HRCT reports multiple different, often synonymous, German and English terms are used. The variety of terms impede understanding and acceptance of HRCT. Purpose of this paper is to present a scheme, which is based on the anatomic landmarks (secondary lobule), and the density of pathologic changes, as well as a glossary from the German HRCT-literature, including suitable terms, definitions, synonyms and English terms. Low attenuation changes include emphysemas, air-filled cavities (bullae, cysts, cavitations, honeycombing) and bronchial dilatation, changes with increased density consist of diffuse (ground glass opacity, consolidation) and focal processes (reticular and nodular densities). …
Increased airway inflammatory cells in endurance athletes: what do they mean?
2003
Background Inflammatory cells are increased in the airways of end urance athletes, but their role in causing exercise-induced respiratory symptoms and bronchoconstriction, or their possible long-term consequences, are uncertain. Aim To put the results of athlete studies in perspective, by analysing the pathogenesis of airway cell changes and their impact on respiratory function. Results Athletes of different endurance sports at rest showed increased airway neutrophils. Elite swimmers and skiers also showed large increases in airway eosinophils and lymphocytes, possibly related to chronic, exercise-related exposure to irritants or cold and dry air, respectively. Post-exercise studies reporte…
Signal processing procedures for the evaluation of the cardiovascular effects in the obstructive sleep apnea syndrome
2002
A new index, the cross-power index (CPI), is proposed to quantify the severity of obstructive sleep apnea syndrome (OSAS) in terms of its cardiovascular effects. On the basis of the influences that recurring drops in oxygen saturation have on systolic blood pressure variability of OSAS patients, CPI is defined as the integral of the cross-spectrum modulus between systolic blood pressure and oxygen saturation. In a test group of 22 subjects, CPI correctly identified all 15 OSAS patients included in the pool. Moreover, evaluation of CPI in six OSAS patients sleeping with and without a CPAP (continuous positive airway pressure) device demonstrated that CPAP treatment substantially reduced the …
Effectiveness of mandibular advancement appliances in treating obstructive sleep apnea syndrome: A systematic review
2015
Objectives/Hypothesis Mandibular advancement devices are an alternative to continuous positive airway pressure for patients with mild or moderate obstructive sleep apnea/hypopnea syndrome (OSAHS). The main aim of this review was to assess the effectiveness of different devices in treating OSAHS, based on polysomnographic measurements such as the apnea/hypopnea index (AHI) and oxygen saturation, and on changes in the upper airway and improvements in the most common symptoms: snoring and somnolence. Their adverse effects were also noted. Study Design Systematic review. Methods Following an exhaustive search in the Medline, Scopus, and Cochrane Library databases, 22 articles published in the p…
C1 Inhibitor-C1¯sComplexes Are Internalized and Degraded by the Low Density Lipoprotein Receptor-related Protein
1997
Like other serpin-enzyme complexes (SECs), proteinase-complexed C1 inhibitor (C1-INH) is rapidly cleared from the circulation and thought to be a neutrophil chemoattractant, suggesting that complex formation causes structural rearrangements exposing a domain which is recognized by specific cell surface receptors. However, the cellular receptor(s) responsible for the catabolism and potential mediation of chemotaxis by C1-INH-protease complexes remained obscure. To determine whether the SEC receptor mediates the binding and potential chemotaxis of C1-INH·C1s, we performed binding assays with HepG2 cells, neutrophils, and monocytes, and the results show that C1-INH·C1s neither bind to these ce…
Electrochemical synthesis of sulfamides.
2021
Herein we demonstrate the first electrochemical synthesis protocol of symmetrical sulfamides directly from anilines and SO2 mediated by iodide. Sulfamides are an emerging functional group in drug design. Highlights are the direct use of SO2 from a stock solution and no necessity of any supporting electrolyte. Overall, the reaction has been demonstrated for 15 examples with yields up to 93%.
