In the present study, modern, non-invasive approaches to assess dietary carotenoids, such as skin measurements and an app-based short dietary record (ASDR), were compared with conventional methods such as plasma status and handwritten 3-day dietary records. In an 8-week observational study, 21 healthy participants aged 50-65 years recorded their daily consumption of carotenoid-rich fruits and vegetables via a specially developed ASDR. Anthropometry, blood samplings and assessment of skin carotenoids via Raman and reflection spectroscopy were performed at baseline, after four weeks and at the end of the study. App-based intake data showed good correlations with plasma α-carotene (r = 0.74, p < 0.0001), β-carotene (r = 0.71, p < 0.0001), and total plasma carotenoids (r = 0.65, p < 0.0001); weak correlations with plasma lutein/zeaxanthin and β-cryptoxanthin (both r = 0.34, p < 0.05); and no correlation with plasma lycopene. Skin measurements via reflection and Raman spectroscopy correlated well with total plasma carotenoids (r = 0.81 and 0.72, respectively; both p < 0.0001), α-carotene (r = 0.75-0.62, p < 0.0001), and β-carotene (r = 0.79-0.71, p < 0.0001); moderately with plasma lutein/zeaxanthin (both r = 0.51, p < 0.0001); weakly with plasma β-cryptoxanthin (r = 0.40-0.31, p < 0.05); and showed no correlation with plasma lycopene. Skin measurements could provide a more convenient and noninvasive approach of estimating a person's fruit and vegetable consumption compared to traditional methods, especially in studies that do not intend blood sampling. ASDR records might function as a suitable, convenient tool for dietary assessment in nutritional intervention studies.}, language = {en} } @article{KebdaniLehnertMichael2021, author = {Kebdani, Zaki and Lehnert, Martin and Michael, Sabrina}, title = {Hygienisch sicher reisen? - Der {\"o}ffentliche Verkehr in der Pandemie -}, series = {Eisenbahntechnische Rundschau (ETR)}, volume = {2021}, journal = {Eisenbahntechnische Rundschau (ETR)}, number = {9}, publisher = {DVV Media Group}, issn = {0013-2845}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:526-opus4-16716}, pages = {16 -- 21}, year = {2021}, abstract = {Entsprechend aktueller wissenschaftlicher Studien ist das Risiko, sich mit SARS-CoV-2 im {\"o}ffentlichen Verkehr zu infizieren, nicht h{\"o}her als im h{\"a}uslichen Umfeld.

This study addresses the current issue of identifying stress states using photoplethysmography signals obtained from the wearable Shimmer 3 sensor. The purpose of the study was to establish an effective approach for stress detection, specifically through the analysis of heart rate variability changes during different states: rest and stress. A distinctive feature of the research is the use of the air raid siren sound as a stress factor. The research methodology includes the collection and analysis of biosignals, allowing for the assessment of cardiovascular system functioning under the impact of stress factors. The results of the study demonstrated significant differences in heart rhythm indicators depending on the person's state, highlighting the potential of these metrics as a tool for health monitoring and stress detection. The paper proposes a new approach to using photoplethysmography for assessing stress responses, which may contribute to the development of personalized stress management methods.}, language = {en} } @misc{TomaschewskiEbner2004, author = {Tomaschewski, Georg and Ebner, Lothar}, title = {Extrakt aus roten Weintrauben - Gewinnung und Einsatz in „Functional Foods"}, series = {Wissenschaftliche Beitr{\"a}ge 2004}, volume = {9}, journal = {Wissenschaftliche Beitr{\"a}ge 2004}, issn = {0949-8214}, doi = {10.15771/0949-8214_2004_1_12}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:526-opus4-4069}, pages = {74 -- 81}, year = {2004}, abstract = {Um die ersten widerspr{\"u}chlichen Studien {\"u}ber die Wirkung von Rotwein auf Herz-Kreislauf-Erkrankungen vergleichbar zu machen, hat in den 80er Jahren die Weltgesundheitsorganisation (WHO) in vielen L{\"a}ndern der Erde ein wissenschaftliches Untersuchungsprogramm durchgef{\"u}hrt. Im MONICA-Projekt (World Health Organisation Multinational Monitoring of Trends and Determinants of Cardiovascular Disease) wurden die Ern{\"a}hrungsgewohnheiten und die HK-Mortalit{\"a}t (Herz-Kreislauf Mortalit{\"a}t) in verschiedenen L{\"a}ndern der Welt verglichen.

Als Maß f{\"u}r die Ern{\"a}hrungsgewohnheiten der Bev{\"o}lkerung wurde der t{\"a}gliche Verbrauch an Milchfett in Kalorien verglichen und der HK-Mortalit{\"a}t gegen{\"u}bergestellt. Zu den Ergebnissen wurden von franz{\"o}sischen Forschern differenzierte Aussagen getroffen. [1] Aus diesen epidemiologischen Untersuchungen ergibt sich, dass die H{\"a}ufigkeit der Herz-Kreislauf-Erkrankungen in Europa und selbst innerhalb Frankreichs von Norden nach S{\"u}den abnimmt. Auf Grund des t{\"a}glichen Verzehrs von Milchfett in Frankreich, vergleichbar mit dem in Deutschland, m{\"u}ssten die Franzosen auch die gleiche H{\"a}ufigkeit an Herz-Kreislauf-Erkrankungen haben. Das ist aber nicht der Fall, die Sterblichkeitsrate ist in Deutschland etwa doppelt so hoch. Allgemein wird das Ph{\"a}nomen von Medizinern und Ern{\"a}hrungsphysiologen als „French Paradoxon" bezeichnet.
