Many people suffer from dry mouth (xerostomia) due to radiotherapy treatment of head and neck cancer, diseases like Sjogren’s syndrome or as adverse effects to prescribed medications. Salivary substitute products like gels or sprays are often used for treatment. Efficacy of those oral care products are regularly assessed by validated or even not validated questionnaires. To determine the adhesion effect over time more objectively a new and sensitive method was established. The following study was designed to assess the dwell time of different oral care products in vitro.

Mangifera indica fruit preparation (Careless™) activates the evolutionary conserved metabolic sensors sirtuin 1 and adenosine monophosphate-activated protein kinase, which have been identified as playing a key role in microcirculation and endothelial function. Here, an acute effect of a single dose of 100 mg or 300 mg Careless™ on microcirculation was investigated in a randomized, double-blind, crossover pilot study in ten healthy women to determine the effective dosage.

In two work packages of the MARK-AGE project, 37 immunological and physiological biomarkers were measured in 3637 serum, plasma or blood samples in five batches during a period of 4 years. The quality of the serum and plasma samples was very good as judged by the low number of biomarker measurements (only 0.2%) that were rejected because of a high hemolysis, icteria or lipemia of the samples. Using quality control samples, day-to-day and batch variations were determined. The mean inter-assay variation of the five batches were all below 8%, with an average inter-assay coefficient of variation of all biomarkers of 4.0%.

Arthropathies present a major challenge for the public health system, both in terms of epidemiology and health economics, particularly against the background of demographic changes in the Western world. Much attention must be paid to prevention, because of the limited options and high technical and financial expenditure with respect to treatment. Among other factors, nutrition plays an important role.

Mit der VO (EG) Nr. 1924/2006 über nährwert- und gesundheitsbezogene Angaben über Lebensmittel (sog. „Health Claims Verordnung“ – HCV) wird Lebensmittelunternehmen die Möglichkeit eröffnet, Lebensmittel mit einer wirkbezogenen Aussage zu vermarkten. Acht Jahre nach dem Inkrafttreten der Verordnung sollen in der gebotenen Kürze regulatorische Entwicklungen in der Umsetzung der HCV nachvollzogen und Informationen zur Vorgehensweise bei der Zulassung von Health Claims gegeben werden. Darüber hinaus wird auf die Anforderungen an eine wissenschaftliche Absicherung von gesundheitsbezogenen Angaben und die dafür notwendigen Evidenzkriterien eingegangen. Von der EFSA wurden hohe Hürden für die wissenschaftliche Absicherung aufgestellt. Mit dem Artikel sollen Schwächen bei der bisherigen Vorgehensweise dargestellt werden, ein Überblick über die noch offenen Themen gegeben und Möglichkeiten zur Bewältigung der wissenschaftlichen Anforderungen aufgezeigt werden.

Many relevant EU projects were funded during last decade and MARK-AGE (European Study to Establish Biomarkers of Human Ageing) was the first focused on the identification of biomarkers connecting itself with a previous funded project, i.e. GEHA (Genetic of Healthy Ageing) that identified European families with longevity component (Franceschi et al., 2007). MARK-AGE was mainly a cross sectional study, based on definite assumptions and focused on an age range between 34 and 75 years, in order to identify early biomarkers of biological vs. chronological age, potentially capable of predicting the rate of ageing later in life.
