[Anti-inflammatory action of a hyaluronic acid-chondroitin sulfate preparation in an in vitro bladder model]

Interstitial cystitis and BPS (bladder pain syndrome) are chronic inflammatory diseases of the bladder. They are as yet imperfectly understood diseases, possibly originating from damage to the glycosaminoglycan layer of the bladder epithelium . Hyaluronic acid-containing preparations are currently utilised for palliation of the symptoms and protection of the bladder epithelium . The aim of the work described here was the evaluation of one of these preparations containing chondroitin sulfate together with hyaluronic acid.

Regulatory effects of a fermented food concentrate on immune function parameters in healthy volunteers

Nutrition is known to influence the immune system and can thereby modulate resistance to infection. The objective of this clinical trial was to assess the influence of a cascade-fermented food consisting of fruits, nuts, and vegetables rich in polyphenols (Regulat) on the immune system in healthy volunteers.

[An improved model of a catheterised human bladder for screening bactericidal agents]

Catheter encrustation and associated blockage by a crystalline Proteus mirabilis biofilm constitute a continuous problem in long-term catheterised patients. The objective of the present work was to verify a new, physiological bladder model possessing the ability to show that triclosan-blocking solutions exert bactericidal and bacteriostatic activities.

The application of normal, SV40 T-antigen-immortalised and tumour-derived oral keratinocytes, under serum-free conditions, to the study of the probability of cancer progression as a result of environmental exposure to chemicals

In vitro models are currently not considered to be suitable replacements for animals in experiments to assess the multiple factors that underlie the development of cancer as a result of environmental exposure to chemicals. An evaluation was conducted on the potential use of normal keratinocytes, the SV40 T-antigen-immortalised keratinocyte cell line, SVpgC2a, and the carcinoma cell line, SqCC/Y1, alone and in combination, and under standardised serum-free culture conditions, to study oral cancer progression.

Vitamin A and beta-carotene supply of women with gemini or short birth intervals: a pilot study

An adequate supply of vitamin A during pregnancy and breastfeeding plays an important role for development of foetus and neonate, especially in lung development and function. Aim of this pilot study was to analyze vitamin A and beta-carotene status and to investigate the contribution of nutrition to the vitamin A and beta-carotene supply in mother-infant pairs of gemini or births within short birth intervals.

Comparison of the relative bioavailability of different coenzyme Q10 formulations with a novel solubilizate (Solu Q10)

The relative bioavailability of coenzyme Q10 (CoQ10) is markedly influenced by its delivery systems. The aim of this study was to compare four standard CoQ10 supplements available on the market with a novel solubilizate formulation of CoQ10 (Solu Q10). Pharmacokinetic parameters were assessed in 54 healthy volunteers after single and multiple intakes of 60 mg CoQ10 over a time period of 14 days.
