T P Oscar
The flow pack wrapper is a popular packaging choice for retail sale of whole chickens. However, it may provide a favorable environment for growth and spread of Salmonella within the package, leading to an outbreak of salmonellosis. To investigate this possibility, a process risk model was developed that predicted the risk of salmonellosis from chicken parts prepared from whole chickens sold in flow pack wrappers and subjected to proper storage (6 h at 4°C) or improper storage (72 h at 15°C) before preparation...

BACKGROUND: The improvement of health-related quality of life (HRQOL) is one of the main treatment goals in end-of-life care. Although definitions and conceptualizations remain heterogeneous, many researchers proposed HRQOL to be considered as subjective patient well-being. However, research on its determinants in palliative care is rare, and little is known about the interplay between psychological and biological variables. OBJECTIVE: The aim of this study was to explain differences in terminally ill patients' acute well-being (AWB) by use of a multimethod approach, examining both self-ratings and physiological predictors...

The purpose of this work was to design and manufacture a 3D range-modulator for scanned particle therapy. The modulator is intended to create a highly conformal dose distribution with only one fixed energy, simultaneously reducing considerably the treatment time. As a proof of concept, a 3D range-modulator was developed for a spherical target volume with a diameter of 5 cm, placed at a depth of 25 cm in a water phantom. It consists of a large number of thin pins with a well-defined shape and different lengths to modulate the necessary shift of the Bragg peak...

Salmonella enterica is a bacterial species that is a major cause of illness in humans and food-producing animals. S. enterica exhibits considerable inter-serovar diversity, as evidenced by the large number of host adapted serovars that have been identified. The development of methods to assess genome diversity in S. enterica will help to further define the limits of diversity in this foodborne pathogen. Thus, we evaluated a PCR assay, which targets prophage integrase genes, as a rapid method to investigate S...

Background: Suffering from tinnitus causes mental distress in most patients. Recent findings point toward a diminished activity of the brain's default-mode network (DMN) in subjects with mental disorders including depression or anxiety and also recently in subjects with tinnitus-related distress. We recently developed a therapeutic intervention, namely the Heidelberg Neuro-Music Therapy (HNMT), which shows an effective reduction of tinnitus-related distress following a 1-week short-term treatment. This approach offers the possibility to evaluate the neural changes associated with the improvements in tinnitus distress...

The Heidelberg Form for Emotion Regulation Strategies (HFERST) was developed to complement previous emotion regulation (ER) questionnaires and addresses some of their limitations by measuring eight ER strategies. An initial item pool was developed in German following expert discussions and adaptation of the items from existing ER scales. Following a stepwise selection based on the experts' judgments, 32 items with the best content validity were chosen. Results of an exploratory factor analysis in Study 1 ( N = 399) and two confirmatory factor analyses in Studies 2 ( N = 715) and 3 ( N = 408) supported the eight-factor structure of the HFERST and provided evidence for its internal consistency, construct and criterion validity, and clinical utility...
