After full macular translocation (MT) surgery with 360 degrees retinotomy, the fovea is rarely identifiable. Our aim was to verify the position of the fovea, to determine how patients fixate after MT and to examine distribution and optical density of macular pigment (MP).

The aim of this double-blind, placebo-controlled cross-over design trial was to assess the safety of a multi-vitamin preparation containing nicotinic acid in a physiological dose. Seventy-two healthy volunteers took part in this trial. At six consecutive time-points, we systematically documented blood pressure, pulse, skin temperature and flushing symptoms after an oral dose of up to 50.1 mg nicotinic acid. The results suggest that nicotinic acid in a dosage of 16.7 mg does not cause flushing symptoms. In higher doses up to 50.1 mg, flushing symptoms are sporadically possible. There was no physiologically relevant change regarding the central metabolic parameters blood pressure, pulse and skin temperature.

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.

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.

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.

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.
