2015
5548 Background: In ICON7, progression-free survival (PFS) was significantly improved in patients (pts) receiving BEV with front-line CP and continued as a single agent [Perren 2011] but no overall...
Central Nervous System Malignancies
2021
The primitive neoplasms of the central nervous system (CNS) are a rare and heterogeneous group of malignancies. Brain metastases (BMs) are the most frequent intracranial tumor, and their incidence is rising in the last few decades. Primary tumors more often complicated by BMs are lung cancer, breast cancer, and melanoma. Neuroimaging techniques, mainly magnetic resonance imaging (MRI), play a key role for the diagnosis of BMs. The management of BMs is based on a multimodal approach, including symptomatic treatment, local treatment, such as surgery, stereotactic radiosurgery (SRS), and whole brain radiotherapy (WBRT), and systemic therapy, such as chemotherapy, target therapy, or immunothera…
Gains and losses related to career transitions within organisations
2014
Abstract With this study we aim to look at potential gains and losses in terms of higher career satisfaction and increased strain levels as a consequence of intraorganisational upward career transitions. Following the idea of a matching principle, we further expected stressors to mediate the relationship between transitions and strain, and resources to mediate the relationship between transitions and career satisfaction. Altogether, N = 581 employees from 11 German organisations filled in an online questionnaire twice, with a time lag of one year. About 20% of the respondents stated having experienced upward transitions. SEM analyses using latent difference scores for the mediators and depe…
Influencia del procesado industrial sobre las características químico-físicas y contenido en lípidos y antioxidantes del salvado de arroz
2009
Se investigaron las características químico-físicas de los salvados de arroz en distintos momentos de su procesado industrial, incluyendo materia prima (salvados de arroz blanco y vaporizado), salvado peletizado y salvado desgrasado. Se determinó la humedad, la acidez y el índice de peróxidos. Utilizando extractos en éter de petróleo y cromatografía de gases, se estableció el contenido lipídico total y los perfiles de los ácidos grasos. Mediante HPLC se determinaron los tocoferoles y el γ-orizanol. El salvado de arroz vaporizado mostró la mayor concentración de lípidos y la menor acidez, lo que indica que el vaporizado es el proceso más eficaz para estabilizar el salvado. Los ácidos oleico,…
Expression of the Vitellogenin Gene in the Liver of Juvenile Whitefish (Coregonus lavaretus L. s.l.) Exposed to Effluents from Pulp and Paper Mills
1999
Juvenile whitefish (Coregonus lavaretus L. s.l.) were exposed by caging in the field to diluted effluents from three operating pulp, paper, and paperboard mills in Southern Lake Saimaa, Finland. The expression of the vitellogenin gene, used as a biomarker of estrogenic contamination of effluents, was measured using a Northern blotting method. Increased mRNA levels, the most specific and reliable evidence for estrogen receptor-mediated actions in vivo, were found in fish caged in the vicinity of one of three mills studied. This mill was found to discharge wood-derived compounds, such as sterols and resin acids, into Lake Saimaa in amounts considerably exceeding those from the other two mills…
Parental phone use during mealtime with toddlers and the associations with feeding practices and shared family meals: a cross-sectional study
2021
Abstract Background Positive parental feeding practices and a higher frequency of family meals are related to healthier child dietary habits. Parents play an essential role when it comes to the development of their child’s eating habits. However, parents are increasingly distracted by their mobile phone during mealtimes. The aim of this study was to describe the feeding practices and daily shared family meals among parents who use and do not use a mobile phone during mealtimes, and further to explore the associations between the use of a mobile phone during mealtimes and feeding practices and daily shared family meals, respectively. Methods Cross-sectional data from the Food4toddler study w…
Classification of human placental villi. I. Histology.
1979
The classification of human placental villi was reviewed on the basis of material prepared by means of special methods. The material from in situ normal-term placentae was biopsied by aspiration into glutaraldehyde. The classification was made on the basis of light-microscopic observations of semithin sections, reconstructions from serial sections, and scanning-electron micrographs. The peripheral villous tree is roughly divided into stem (ramuli), intermediate and terminal villi. The intermediate villi may be further subdivided as mature and immature types, which are found between the stem and terminal villi. Some of the terminal villi possess a local specialization described as the neck r…
Nitric oxide synthase in the enteric nervous system of the guinea-pig: a quantitative description
1994
The distribution and abundance of nitric oxide synthase (NOS)-containing neurons and their terminals in the gastrointestinal tract of the guinea-pig were examined in detail using NADPH diaphorase histochemistry and NOS immunohistochemistry. NOS-containing cell bodies were found in the myenteric plexus throughout the gastrointestinal tract and in the submucous plexus of the stomach, colon and rectum. NOS-containing neurons comprised between 12% (in the duodenum) and 54% (in the esophagus) of total myenteric neurons. In the ileum, NOS neurons represented 19% of total myenteric neurons. Most of the NOS neurons throughout the gastrointestinal tract possessed lamellar dendrites and a single axon…
[Regular Paper] Detection of H. pylori Induced Gastric Inflammation by Diffuse Reflectance Analysis
2018
Spectral acquisitions contain rich information and thus, are promising modalities for early detection of gastric diseases. In this study, we analyze the diffuse reflectance of the gastric inflammatory lesions induced by the bacterium H. pylori in the mouse stomach. A pipeline has been designed to characterize and classify spectra acquired on mice. The pipeline is based on a band clustering algorithm followed by the computation of meaningful division and subtraction features and by classification with a linear SVM classifier. Currently, the pipeline is able to recognize inflamed stomach's spectra with an accuracy of 98%. These results are promising and the same pipeline could be adapted for …
Functional Adhesion of Pectin Biopolymers to the Lung Visceral Pleura
2021
Pleural injuries and the associated “air leak” are the most common complications after pulmonary surgery. Air leaks are the primary reason for prolonged chest tube use and increased hospital length of stay. Pectin, a plant-derived heteropolysaccharide, has been shown to be an air-tight sealant of pulmonary air leaks. Here, we investigate the morphologic and mechanical properties of pectin adhesion to the visceral pleural surface of the lung. After the application of high-methoxyl citrus pectin films to the murine lung, we used scanning electron microscopy to demonstrate intimate binding to the lung surface. To quantitatively assess pectin adhesion to the pleural surface, we used a custom ad…
