Beeinflussung der Darmmotorik durch Xylit
1963
Mit Hilfe der Tuschetransportmethode wurde an Mausen die Darmwirksamkeit von Xylit gepruft. Durch perorale Xylitgaben in Mengen von 0,5–1,0 g/kg Korpergewicht wurde die Darmtatigkeit deutlich angeregt. Kleinere Xylit-Dosen hatten demgegenuber keinen Einflus auf die Darmperistaltik. Die Anregung der Darmmotorik durch hohe Xylitgaben wird als osmotischer Effekt gedeutet.
Facilitated Oxygen Transport
2010
The amount of dioxygen an organism needs for aerobic metabolism depends on many factors, size and activity being the most important. However, as an approximate figure, we may say that a typical higher eukaryote will utilize about 3.5 ml dioxygen kg−1 body weight per minute. This must reach the tissues where active metabolism is occurring and be maintained there at a steady-state pressure of approximately 2 Torr. This will assure a sufficient rate of delivery to mitochondria and allow continued utilization therein for oxidative reactions (see Chap. 4). The problem faced by the organism is how to assure sufficient delivery to all the tissues, even those buried deep in the body, sometimes whil…
Predictors of mucositis in oropharyngeal and oral cavity cancer in patients treated with volumetric modulated radiation treatment: A dose-volume anal…
2015
Background The purpose of this study was to assess predictors of mucositis in oropharyngeal and oral cavity cancer after definitive or adjuvant volumetric modulated arc radiotherapy (VMAT) +/− chemotherapy. Methods Fifty patients were evaluated. Statistical analysis was performed for the following parameters as potential predictors of mucositis ≥ G2: total oral mucosa and oral mucosa minus target high-low radiation dose regions (planning target volumes [PTVs]), mean dose (Dmean), maximum dose (Dmax), chemotherapy, weight loss, and dysphagia. Results Mucositis ≥ G2 was found to be statistically related to chemotherapy, weight loss, dysphagia ≥ G2, total oral mucosa Dmean ≥50 Gy and Dmax ≥65 …
Epidemiologie von Hirntumoren im Kindesalter
2000
The German Childhood Cancer Registry (GCCR) was established in 1980. From 1980 to 1997 4,447 CNS tumours in children below 15 years of age have been reported to the registry. From 1988 to 1997 the average annual incidence was 2.5/100,000 children. This corresponds to 19.2% of the registered diseases. Compared with incidence rates reported from other developed countries one can estimate that there is about 25% underreporting of CNS tumours in the GCCR. This is in contrast to the relatively complete ascertainment of other childhood malignancies (above 95%). Based on 3012 incident cases from 1988 to 1997 the Kaplan-Meier-estimate of 5-year-survival probability is 65% for all CNS tumours and 54…
Percentile Curves for Multiple Physical Fitness Components Among Chinese Han Children and Adolescents Aged 7–18 Years From a National Survey Based on…
2022
Introduction: To develop sex- and age-specific percentile curves for seven physical fitness components for Chinese Han children and adolescents aged 7–18 years based on the total and the normal weight population using a nationally representative sample.Methods: A total of 214,228 Chinese Han children and adolescents aged 7–18 years old with all nutritional status and 161,999 with normal weight were examined. Seven physical fitness components [forced vital capacity (FVC), standing long jump (SLJ), 50-m dash, sit-and-reach (SR), grip strength (GS), body muscle strength (BMS), and endurance running (ER)] were measured, and percentile curves for each physical fitness component at the 20th, 40th…
Using ATR-FTIR Spectroscopy To Design Active Antimicrobial Food Packaging Structures Based on High Molecular Weight Chitosan Polysaccharide
2007
ATR-FTIR spectroscopy has been used in this study to characterize the molecular mechanisms and kinetic processes that take place when a chitosonium acetate thin coating is put in contact with water solutions, Staphylococcus aureus solutions, microbial nutrient solutions, and with a high water activity TSA hydrogel medium to simulate the effect of direct contact with high moisture foods such as fresh meats, fish, and seafood products or beverages. The results of this work suggest that the biocide carboxylate groups that form when chitosan is cast from acetic acid solutions are being continuously evaporated from the formed film in the form of acetic acid (mechanism I) in the presence of envir…
Polychlorinated phenols and their metabolites in soil and earthworms of sawmill environment
1990
Abstract Topsoil and earthworm samples collected from three Finnish sawmill environments were analysed for polychlorinated phenols, 2,3,4,6-tetrachloro- and pentachlorophenol, and their metabolites. Analyses were carried out by gas chromatography/mass spectrometry using a selected ion monitoring technique and by dual-channel gas chromatography using quartz capillary columns and two electron capture detectors. The total chlorophenol concentrations ranged from ca. 260 to 480 μg/g (dry weight) in soil and from ca. 140 to 3500 μg/g fat in earthworms. The most important metabolites in soil were chlorinated dihydroxy-benzenes (also at ppm level); only traces of chlorinated anisoles were detected …
Periphyton growth and diatom community structure in a cooling water pond
1982
Periphyton (Aufwuchs) accumulation was measured on artificial substrates in a pond in central Finland which receives warm cooling-water effluent from a power plant. The growth of periphyton was generally more rapid on the substrates during the first two weeks of colonization near the inflow of the warm water effluent than in the middle of the pond. The maximum accumulation of periphyton was in spring and autumn (dry weight maximum at warm effluent was in spring 3.5 mg DW cm−2,2.65 mg AFDW cm−2; chlorophyll a maximum 3.96 µg cm−2 was found in autumn at pond-middle station). During mid-winter months the growth was strongly limited by solar radiation, but the growth was also slow at both stati…
Partial vinylphenol reductase purification and characterization from Brettanomyces bruxellensis
2008
International audience; Brettanomyces is the major microbial cause for wine spoilage worldwide and causes significant economic losses. The reasons are the production of ethylphenols that lead to an unpleasant taint described as 'phenolic odour'. Despite its economic importance, Brettanomyces has remained poorly studied at the metabolic level. The origin of the ethylphenol results from the conversion of vinylphenols in ethylphenol by Brettanomyces hydroxycinnamate decarboxylase. However, no information is available on the vinylphenol reductase responsible for the conversion of vinylphenols in ethylphenols. In this study, a vinylphenol reductase was partially purified from Brettanomyces bruxe…
Pullulan and dextran: uncommon composition dependent Flory-Huggins interaction parameters of their aqueous solutions.
2008
Vapor pressure measurements were performed for aqueous solutions of pullulan ( M w 280 kg/mol) and dextran ( M w 60 and 2100 kg/mol, respectively) at 25, 37.5, and 50 degrees C. The Flory-Huggins interaction parameters obtained from these measurements, plus information on dilute solutions taken from the literature, show that water is a better solvent for pullulan than for dextran. Furthermore, they evince uncommon composition dependencies, including the concurrent appearance of two extrema, a minimum at moderate polymer concentration and a maximum at high polymer concentration. To model these findings, a previously established approach, subdividing the mixing process into two clearly separa…
