Publikation: 08. März 2017 Reduced muscular fatigue after a 12-week leucine-rich amino acid supplementation
Age-related muscle loss is characterised by a progressing decrease in muscle mass, strength and function. Besides resistance training and physical activity, appropriate nutrition that is rich in protein, especially branched-chain amino acids, is very important to support training effects and positively influence the protein synthesis to degradation ratio.
The purpose of this study was to evaluate the effect of a 12-week leucine-rich amino acid supplementation in combination with moderate training.
Publikation: 10. Februar 2017 Effects of Mangifera indica (Careless) on Microcirculation and Glucose Metabolism in Healthy Volunteers
A commercial Mangifera indica fruit powder (Careless) showed beneficial acute effects on microcirculation in a randomized, double-blind, crossover pilot study. Here, long-term effects on microcirculation and glucose metabolism were investigated in a double-blind, randomized, placebo-controlled, 3-arm parallel-design study in healthy individuals.
Publikation: 02. Februar 2017 Effects of an L-arginine-based multi ingredient product on endothelial function in subjects with mild to moderate hypertension and hyperhomocysteinemia - a randomized, double-blind, placebo-controlled, cross-over trial
Nutrition plays an important role in prevention and management of cardiovascular diseases (CVD) in early stages. Recent research demonstrated beneficial effects of various nutritional ingredients on vascular health. The aim of the current study was to evaluate the effects of an L-arginine-based multi ingredient product (AbMIP) on vascular function.
Publikation: 04. Januar 2017 Effect of Two Different Multimicronutrient Supplements on Vitamin D Status in Women of Childbearing Age: A Randomized Trial
The German Nutrition Society raised in 2012 the recommended daily vitamin D intake from 200 to 800 international units (IU) to achieve 25-hydroxyvitamin D (25(OH)D) levels of at least 50 nmol/L, even when endogenous vitamin D synthesis is minimal such as in winter. We aimed to evaluate this recommendation in women of childbearing age.
Publikation: 30. September 2016 Plasma Carotenoids, Tocopherols, and Retinol in the Age-Stratified (35-74 Years) General Population: A Cross-Sectional Study in Six European Countries.
Blood micronutrient status may change with age. We analyzed plasma carotenoids, α-/γ-tocopherol, and retinol and their associations with age, demographic characteristics, and dietary habits (assessed by a short food frequency questionnaire) in a cross-sectional study of 2118 women and men (age-stratified from 35 to 74 years) of the general population from six European countries. Higher age was associated with lower lycopene and α-/β-carotene and higher β-cryptoxanthin, lutein, zeaxanthin, α-/γ-tocopherol, and retinol levels
Publikation: 29. August 2016 Analysis of the machinery and intermediates of the 5hmC-mediated DNA demethylation pathway in aging on samples from the MARK-AGE Study.
Gradual changes in the DNA methylation landscape occur throughout aging virtually in all human tissues. A widespread reduction of 5-methylcytosine (5mC), associated with highly reproducible site-specific hypermethylation, characterizes the genome in aging. Therefore, an equilibrium seems to exist between general and directional deregulating events concerning DNA methylation controllers, which may underpin the age-related epigenetic changes. In this context, 5mC-hydroxylases (TET enzymes) are new potential players.

Publikation: 05. August 2016 Effect of consumption of chicory inulin on bowel function in healthy subjects with constipation
Constipation is among the most common health impairments in Western countries. This study aimed to determine the effect of the chicory-derived fermentable dietary fiber Orafti® Inulin on stool frequency in healthy subjects with constipation. The study was conducted according to recent guidance documents for investigating bowel function and used a randomized, double-blind, placebo-controlled, cross-over design with a 2-week wash-out phase. Each study period comprised a run-in phase followed by 4 weeks daily intake of 3 × 4g inulin or maltodextrin (placebo). Forty-four healthy volunteers with constipation documented stool frequency and consistency, gastrointestinal characteristics and quality of life. Consumption of Orafti® Inulin significantly increased stool frequency compared to placebo (median 4.0 [IQR 2.5-4.5] versus 3.0 [IQR 2.5-4.0] stools/week, p = 0.038). This was accompanied by a softening of stools and trend toward higher satisfaction versus placebo (p = 0.059). In conclusion, Orafti® Inulin was effective in volunteers with chronic constipation and significantly improved bowel function.
Publikation: 11. Mai 2016 Age-dependent expression of DNMT1 and DNMT3B in PBMCs from a large European population enrolled in the MARK-AGE study.
Aging is associated with alterations in the content and patterns of DNA methylation virtually throughout the entire human lifespan. Reasons for these variations are not well understood. However, several lines of evidence suggest that the epigenetic instability in aging may be traced back to the alteration of the expression of DNA methyltransferases. Here, the association of the expression of DNA methyltransferases DNMT1 and DNMT3B with age has been analysed in the context of the MARK-AGE study, a large-scale cross-sectional study of the European general population.
Publikation: 22. April 2016 Nutritional Biomarkers of Aging
The process of aging is determined by a complex interaction of endogenous factors such as genes combined with influencing exogenous factors such as nutrition and lifestyle. The progressive accumulation of damage caused by reactive species is often called oxidative stress and is associated with age-related diseases and aging. Defense mechanisms against oxidative stress involve the antioxidative network in which nutritional factors could intervene in a regulatory manner.
Publikation: 15. März 2016 Using mid infrared technology as new method for the determination of the dwell time of salivary substitutes on three dimensional gingiva models
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.
