Damage of cartilage structures in the head and neck region as well as in orthopedic sites are frequently caused by trauma, tumor resection, or congenital defects. Despite a high demand in many clinical fields, until today, no adequate cartilage replacement matrix is available for these fields of application. Materials that are clinically applied for joint(More)
The engineering of living tissues in vivo requires new concepts in cell culture technology. In contrast to conventional cell cultures, the development of tissues depends on a three-dimensional arrangement of cells and the formation or synthesis of an appropriate extracellular matrix. Special emphasis is given to the major role of the extracellular matrix(More)
The aim of this study was to determine whether the biomechanical and biochemical properties of tissue-engineered human septal cartilage vary with donor age and in vitro culture time. Chondrocytes were isolated from human septal cartilage of patients from 15 to 60 year old and maintained in primary monolayer culture for 14 days. Cells were seeded onto 0.5%(More)
Stem cells derived from pancreatic tissue are well characterized and exhibit a broad plasticity as they can differentiate beyond lineage boundaries into many cell types. The aim of this study was the comparative characterization of pancreatic stem cells with one other derivate of the embryonic foregut, namely salivary glands, for the existence of similar(More)
BACKGROUND The prognostic role of circulating tumor cells (CTCs) after induction chemotherapy using docetaxel, cisplatin and fluorouracil (TPF) prior to surgery and adjuvant (chemo)radiation in locally advanced oral squamous cell cancer (OSCC) was evaluated. METHODS In this prospective study, peripheral blood samples from 40 patients of the phase II study(More)
Bacterial nanocellulose (BNC), synthesized by the bacterium Gluconacetobacter xylinus, is composed of highly hydrated fibrils (99 % water) with high mechanical strength. These exceptional material properties make BNC a novel biomaterial for many potential medical and tissue engineering applications. Recently, BNC with cellulose content of 15 % has been(More)
New cell culture techniques raise the possibility of creating cartilage in vitro with the help of tissue engineering. In this study, we compared two resorbable nonwoven cell scaffolds, a polyglycolic acid/poly-L-lactic acid (PGA/PLLA) (90/10) copolymer (Ethisorb) and pure PLLA (V 7-2), with different degradation characteristics in their aptitude for(More)
OBJECTIVES/HYPOTHESIS Septal deviation and hypertrophic inferior turbinates are a frequent cause of nasal breathing disorders. The goal of this study was to prove the effectiveness and safety of three current turbinoplasty techniques. STUDY DESIGN This is a prospective, three-arm, single-blinded, single-center, randomized controlled trial. METHODS Sixty(More)
BACKGROUND Angioedema induced by treatment with angiotensin-converting-enzyme (ACE) inhibitors accounts for one third of angioedema cases in the emergency room; it is usually manifested in the upper airway and the head and neck region. There is no approved treatment for this potentially life-threatening condition. METHODS In this multicenter,(More)
Currently, adult stem cells are attracting significant interest in regenerative medicine and tissue engineering. These cells have been isolated from various tissue sources; however, in most cases, adult stem cells useful for tissue engineering and regeneration are present at a low frequency. High numbers of stem cells with an effective and reliable(More)
