Past, Present and Future Perspectives on Halloysite Clay Minerals
2020
Halloysite nanotubes (HNTs), clay minerals belonging to the kaolin groups, are emerging nanomaterials which have attracted the attention of the scientific community due to their interesting features, such as low-cost, availability and biocompatibility. In addition, their large surface area and tubular structure have led to HNTs’ application in different industrial purposes. This review reports a comprehensive overview of the historical background of HNT utilization in the last 20 years. In particular it will focus on the functionalization of the surfaces, both supramolecular and covalent, following applications in several fields, including biomedicine, environmental science and catalysis.
Systemische Immunsuppression in Zeiten von COVID‐19: Müssen wir umdenken?
2020
Zusammenfassung Die aktuelle SARS‐CoV‐2 Pandemie gefährdet vor allem ältere Menschen mit kardiopulmonalen und metabolischen Vorerkrankungen. In aktueller Diskussion ist jedoch auch, ob Patienten unter immunsuppressiver Therapie ebenfalls ein höheres Risiko haben, im Fall einer COVID‐19‐Erkrankung einen schweren Krankheitsverlauf zu erleiden. Grundsätzlich gibt es derzeit jedoch keine Datenlage für eine generelle Reduktion oder Pausierung einer Immunsuppression bei Patienten mit Autoimmunerkrankungen in Zeiten der SARS‐CoV‐2‐Pandemie. Da es jedoch derzeit weder eine wirksame Therapie, noch einen entsprechenden Impfschutz gibt, sollten wir uns gezielt mit der Problematik chronisch‐immunsuppri…
Ethically Researching Local Impacts of Environmental Change without Travel
2021
Responses to the COVID-19 pandemic, which began in 2020, included local and international travel restrictions alongside limits on face-to-face gatherings. These measures impinged on participatory research examining local impacts of environmental change. In response, many researchers adopted techniques that could be implemented without travel. This article explores some of the consequent research ethics issues.
High Biological Value Compounds Extraction from Citrus Waste with Non-Conventional Methods.
2020
Citrus fruits are extensively grown and much consumed around the world. Eighteen percent of total citrus cultivars are destined for industrial processes, and as a consequence, large amounts of waste are generated. Citrus waste is a potential source of high biological value compounds, which can be used in the food, pharmaceutical, and cosmetic industries but whose final disposal may pose a problem due to economic and environmental factors. At the same time, the emerging need to reduce the environmental impact of citrus waste and its responsible management has increased. For these reasons, the study of the use of non-conventional methods to extract high biological value compounds such as caro…
Big data analytics in healthcare: a systematic literature review
2020
The current study performs a systematic literature review (SLR) to synthesise prior research on the applicability of big data analytics (BDA) in healthcare. The SLR examines the outcomes of 41 stu...

Genetic and Epigenetic Factors of Takotsubo Syndrome: A Systematic Review
2021
Takotsubo syndrome (TTS), recognized as stress’s cardiomyopathy, or as left ventricular apical balloon syndrome in recent years, is a rare pathology, described for the first time by Japanese researchers in 1990. TTS is characterized by an interindividual heterogeneity in onset and progression, and by strong predominance in postmenopausal women. The clear causes of these TTS features are uncertain, given the limited understanding of this intriguing syndrome until now. However, the increasing frequency of TTS cases in recent years, and particularly correlated to the SARS-CoV-2 pandemic, leads us to the imperative necessity both of a complete knowledge of TTS pathophysiology for identifying bi…
„Wir wussten, dass es schwierig wird, doch damit haben wir nicht gerechnet!“ Erfahrungen beim Studieneinschluss von Krebspatient*innen mit Migrations…
2021
Zusammenfassung Hintergrund Der Prozess des Studieneinschlusses von Teilnehmenden ist ein wichtiger Bestandteil und oftmals aufwendiger Arbeitsschritt in wissenschaftlichen Forschungsprojekten. Aufgrund unterschiedlicher finanzieller, organisatorischer und ethischer Rahmenbedingungen stellt die fristgerechte Gewinnung von Teilnehmenden haufig eine Herausforderung dar. In diesem Beitrag berichten wir uber unsere Erfahrungen hinsichtlich des Studieneinschlusses, die wir im Projekt „Psychoonkologische Versorgung von Krebspatienten mit Migrationshintergrund – eine Mixed-Methods-Studie“ (POM) gemacht haben. Methode Die Gewinnung von Teilnehmenden erfolgte uber ambulante hamato-onkologische Schwe…
Toxicity as prime selection criterion among SARS-active herbal medications
2021
We present here a new selection criterion for prioritizing research on efficacious drugs for the fight against COVID-19: the relative toxicity versus safety of herbal medications, which were effective against SARS in the 2002/2003 epidemic. We rank these medicines according to their toxicity versus safety as basis for preferential rapid research on their potential in the treatment of COVID-19. The data demonstrate that from toxicological information nothing speaks against immediate investigation on, followed by rapid implementation of Lonicera japonica, Morus alba, Forsythia suspensa, and Codonopsis spec. for treatment of COVID-19 patients. Glycyrrhiza spec. and Panax ginseng are ranked in …
The Role of Vitamin D as a Biomarker in Alzheimer’s Disease
2021
Vitamin D and cognition is a popular association, which led to a remarkable body of literature data in the past 50 years. The brain can synthesize, catabolize, and receive Vitamin D, which has been proved to regulate many cellular processes in neurons and microglia. Vitamin D helps synaptic plasticity and neurotransmission in dopaminergic neural circuits and exerts anti-inflammatory and neuroprotective activities within the brain by reducing the synthesis of pro-inflammatory cytokines and the oxidative stress load. Further, Vitamin D action in the brain has been related to the clearance of amyloid plaques, which represent a feature of Alzheimer Disease (AD), by the immune cell. Based on the…
