BACKGROUND Recent reports on Achilles tendon lengthening (ATL) have documented rapid healing of chronic plantar neuropathic forefoot ulcers. METHODS Sixty-eight patients with 75 ulcerated neuropathic feet (63 patients with diabetes with 69 ulcerated feet) underwent ATL and were retrospectively studied for chronic plantar ulceration in the forefoot and(More)
BACKGROUND AIMS Culture media for mesenchymal stromal cells (MSCs) are generally supplemented with fetal bovine serum. Human platelet lysate (hPL) has been proven to be a very effective alternative without the risk of xenogeneic infections or immune reactions. In contrast to fetal bovine serum, hPL comprises plasma, and anticoagulants-usually unfractionated(More)
The regenerative potential declines upon aging. This might be due to cell-intrinsic changes in stem and progenitor cells or to influences by the microenvironment. Mesenchymal stem cells (MSC) raise high hopes in regenerative medicine. They are usually culture expanded in media with fetal calf serum (FCS) or other serum supplements such as human platelet(More)
INTRODUCTION Coronary artery disease still remains the primary cause of death in the western industrialized world. Although the clinical value of selective coronary angiography (SCA) is beyond dispute, the associated risk of an invasive approach, the inherent costs and the necessary hospitalization have lead to the development and investigation of novel(More)
Healing and recurrence rates were compared in leg ulcers of different aetiology in 385 patients with 406 chronic leg ulcers. Standard treatment was excision of the ulcer followed by meshed split-skin grafting and correction of superficial venous insufficiency in the area. The median age of the patients was 75 years (range 16-95). After one year 345 patients(More)
Five patients with extensive deep burns developed septicaemia due to Pseudomonas aeruginosa serogroup O-7.8 and phage type 21 or 21/188 shortly after they had been admitted to hospital. Four other burned patients became colonized with the same strain. The source of infection was contaminated tap water used for irrigation of the burns, as part of the(More)
The photomorphogenetic aurea mutant of tomato severely deficient in spectrophotometrically active phytochromes was used to study the light-regulation of the single-copy nuclear gene encoding plastidic glutamine synthetase (GS-2; EC 6.1.3.2). The de-etiolation of dark-grown aurea mutant seedling cotyledons showed an obligatory dependency on blue light. A(More)
The regulation by UV-A or UV-B light of the nuclear gene(s) encoding the plastidic enzyme nitrite reductase (NiR; EC 1.7.7.1) was examined in the cotyledons of tomato (Lycopersicon esculentum L.). Two NiR isoforms designated NiR1 and NiR2 with apparent molecular masses of 63 kDa and 62 kDa, respectively, were detected by immunoblot analysis in total soluble(More)
