OBJECTIVE This study was designed to clarify the role of the receptor activator of nuclear factor kappa B ligand (RANKL) in the process of discus degeneration and spondylarthrosis. It was hypothesized that experimental discus lesion would initiate not only local bone remodelling but also increased osteoclast formation on a location remote to the injury site(More)
The role of Toll-like receptors (TLRs) responding to microbial remnants, indolent biofilms or cellular byproducts in aseptic loosening of joint replacements is unknown. Thus, the effect of titanium (Ti) particles on TLR protein levels was evaluated. To create a model of particle-induced inflammation, an intramedullary stainless steel rod with and without Ti(More)
BACKGROUND The majority of deaths due to acute coronary heart disease (CHD) occur outside hospital, unexpectedly, within the first few hours following the onset of the terminal event. Data on the incidence and nature of acute pathological findings in the affected hearts as seen in routine autopsies are somewhat controversial. Detailed pathological(More)
PURPOSE To study the proteolytic phenomena contributing to the pathogenesis of keratoconus, corneal enzymes with potential to cleave fibrillar collagen were studied. METHODS Immunohistochemical labeling was undertaken of conventional and novel mammalian collagenases (MMP-1, -2, -8, -13, and -14) of the matrix metalloproteinase (MMP) family and other(More)
PURPOSE This study was conducted to determine the eventual presence and activity of EMMPRIN (extracellular matrix metalloproteinase inducer CD147) and interstitial collagenase MMP-1 in the cornea of keratoconus patients and their eventual interrelationship. MMP-1 was chosen because it is able to degrade fibrillar corneal collagens type I and III and might(More)
Usually no distinction is made between female and male salivary glands although cyclic changes of and ⁄ or differences in serum and salivary sex steroid concentrations characterize women and men. Moreover, sexual dimorphism is well recognized in salivary glands of rodents.Salivary glands contain estrogen and androgen receptors and are, according to modern(More)
OBJECTIVE To investigate the expression of vascular endothelial growth factor (VEGF) and its vascular and lymphatic receptors in skin in systemic sclerosis (SSc) compared to systemic lupus erythematosus (SLE), Raynaud's phenomenon (RP) and normal healthy control skin. METHODS Staining was performed using rabbit anti-human antibodies in DAKO TechMate(More)
The most important features that determine the vital role of bone include: a) a continuous supply of calcium, which is indispensible for every cell of the entire organism at all times, and b) the delivery of circulating blood cells and some adult stem cells to keep the body vigorous, ready for self-reparation, and continuously rebuilding throughout life.(More)
The aim of this study was to check the balance between tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), and interleukin-10 (IL-10) in well-developed end-stage disk disease in the disk itself as well as in paradiskal spine. In 6 domestic pigs the cranial bony end plate of the L4 vertebra was perforated to the nucleus pulposus. At 3 months the(More)
