    Description / Table of Contents: Zusammenfassung Die in Seibersdorf zur Aufzucht der Mittelmeerfruchtfliege,Ceratitis capitata (Wiedemann) (Diptera: Tephritidae), verwendete Standardendkomponente der Larvendiät konnte nach Abtötung der von der Erstverwendung verbliebenen Larven oder Puppen mittels Autoklavensterilisation wiederverwendet werden. Eine zur frischen Kontrolldiät vergleichbare, jedoch bezüglich der Länge des Larvenstadiums, der Entwicklung der Puppen nach dem Schlüpfen sowie der Größe der Puppen noch immer schlechtere Fliegenproduktion wurde erreicht, wenn die wiederverwendete, autoklavierte Diät mit Wasser (ca. 40% der Enddiät, w/w) zwecks Rekonstitution zur frischen Diättexture gemischt und mit frischem Starter kombiniert wurde. Eine Anreicherung der wiederverwendeten Diätendkomponente mit geringen Mengen von Nährstoffen ergab keine schlüssigen Resultate. Obwohl Puppen der wiederverwendeten Diät signifikant kleiner als Puppen der Frischdiät-Kontrolle waren, überlebten deren Erwachsene signifikant länger als die Erwachsenen der Kontrolle.
    Notes: Abstract The standard finisher larval diet used at Seibersdorf for rearing the Mediterranean fruit fly,Ceratitis capitata (Wiedemann), was reused following autoclave heat-treatment to kill larvae or pupae remaining from its first use. Only when the spent diet was mixed with water (about 40% of final diet, w/w) to reconstitute fresh-diet texture, and combined with fresh starter, a similar, but still inferior in respect to larval duration and pupal recovery and size, to the fresh finisher diet production of flies was achieved. Enrichment of the autoclaved spent finisher with small quantities of nutrients gave inconclusive results. Although spent-diet pupae were significantly smaller than fresh-diet control pupae, their adults survived significantly longer than control adults.

    Notes: Abstract Previous studies have demonstrated lowered sensory thresholds to esophageal balloon distension in patients with chest pain of undetermined etiology. Whether this finding is specific to patients with chest pain or is simply related to an underlying esophageal motility disorder is unclear. In the present study, distension-induced pain-sensation scores and the effect of repeated balloon distension were compared in patients with chest pain, dysphagia secondary to esophageal dysmotility, and healthy controls. All subjects underwent standard esophageal manometry followed by mid-esophageal balloon distension. Volumes 2.5, 5, 7.5, and 10 ml (each volume repeated three times) were applied in random order in a single-blind fashion, and the pain-sensation score was recorded after each distension. Pain-sensation scores varied directly with balloon volume. Mean pain scores were significantly higher (P〈0.001) in the chest pain group than in either the controls or dysphagia group. There was no significant difference between controls and the dysphagia group, and the motor response to distension was no different between groups. In the controls and dysphagia groups, painsensation score was not significantly different between the first, second, or third distension at a given volume. However, in the chest pain group, pain-sensation scores increased significantly with the second (P=0.004) or third (P=0.002) distension using the same balloon volume. These studies suggest that abnormal esophageal nociception in patients with chest pain of undetermined etiology is not simply related to underlying esophageal motor dysfunction. In addition, chest pain patients display a conditioning phenomenon, further supporting the presence of a visceral sensory abnormality.

    Notes: Abstract Ambulatory esophageal manometry/pH-metry has been used primarily in patients with chest pain of presumed esophageal origin, and it is unclear whether the discriminating power of this test applies to other esophageal symptoms. In the present study, prolonged ambulatory manometry/pH recordings were compared in 17 healthy controls, 12 patients with atypical chest pain, and 11 patients with chest pain and nonstructural dysphagia using the Synectics microdigitrapper system. Chest pain patients tended to have higher values for all the pH variables, but their esophageal motility parameters were no different than controls. On the other hand, the chest pain plus dysphagia group was characterized by a significantly lower proportion of propagated contractions between 10 and 5 cm above the lower esophageal sphincter. This group also tended to have a higher frequency of high-amplitude or prolonged-duration contractions. In comparison to the results of standard stationary esophageal manometry, the prolonged ambulatory recordings were more sensitive in detecting esophageal motor dysfunction in the two patient groups. This study suggests that quantitative analysis of ambulatory pH/motility recordings is a sensitive method of evaluating patients with suspected esophageal dysfunction.

    Description: The aim of this paper is to establish some new fixed point theorems for the superposition operators in locally convex spaces which satisfy the Krein-S̆mulian property. We employ a family of measures of noncompactness in conjunction with the Schauder-Tychonoff fixed point theorem. As an application, the existence of solutions to a quite general nonlinear Volterra type integral equation is considered in locally integrable spaces.MSC: 47H10, 47H08, 47H30.

    Description: In this paper, we provide a new approach for discussing the solvability of a class of operator equations by establishing fixed point theorems in locally convex spaces. Our results are obtained extend some Krasnosel’skii type fixed point theorems. As an application, we investigate the existence and global attractivity of solutions for a general nonlinear integral equation of mixed type of Urysohn and Volterra.MSC: 47H10, 45G10, 45D05.
