Although it is known that innate immunity is important for protecting the body against foreign agents such as bacteria, little is known about elements of the innate immune system that have antitumor activity. This prospective study was designed to investigate the function of human beta-defensin 3 (hBD-3), an important component of the innate immune(More)
BACKGROUND Skin antiseptics are widely used in health-care worldwide. However, there is a need to determine cytotoxicity of these medications on wounds. The aim of this study was to evaluate cytotoxic effects of five clinically used antiseptics on human skin cells. MATERIAL AND METHODS Five clinically used skin antiseptics (Prontosan, Lavasept, Braunol,(More)
Proteomic analysis recently suggested aberrant psoriasin (S100A7) expression in oral squamous cell carcinoma (OSCC). In this study, OSCC specimens and matching normal oral tissues from 45 patients who had undergone ablative surgery were examined. Increased psoriasin expression at mRNA level was observed in OSCC samples by quantitative real-time RT-PCR(More)
In contrast to normal healing wounds, chronic wounds commonly show disturbances in proteins regulating wound healing processes, particularly those involved in cell proliferation and protein degradation. Multidimensional protein identification technology MS/MS was conducted to investigate and compare the protein composition of chronic diabetic foot exudates(More)
BACKGROUND Soft tissue sarcoma (STS) is an anatomically and histologically heterogeneous neoplasia that shares a putative mesenchymal cell origin. The treatment with common chemotherapeutics is still unsatisfying because of association with poor response rates. Although evidence is accumulating for potent oncolytic activity of host defense peptides (HDPs),(More)
Host defense peptides can modulate the innate immune response and boost infection-resolving immunity, while dampening potentially harmful pro-inflammatory (septic) responses. Both antimicrobial and/or immunomodulatory activities are an integral part of the process of innate immunity, which itself has many of the hallmarks of successful anti-infective(More)
BACKGROUND Transfection efficacy after nonviral gene transfer in primary epithelial cells is limited. The aim of this study was to compare transfection efficacy of the recently available method of nucleofection with the established transfection reagent FuGENE6. METHODS Primary human keratinocytes (HKC), primary human fibroblasts (HFB), and a human(More)
Wound infection is a common risk for patients with chronic nonhealing wounds, causing high morbidity and mortality. Currently, systemic antibiotic treatment is the therapy of choice, despite often leading to several side effects and the risk of an insufficient tissue penetration due to impaired blood supply. If systemically delivered, moxifloxacin(More)
The goal of this study was to analyse expression profiles of human epithelial host defence peptides in burned and unburned skin tissue, samples of which were obtained during debridements and snap-frozen in liquid nitrogen. Total RNA was isolated, and cDNA of epithelial host defence peptides and proteins (hCAP-18/LL-37, hBD1-hBD4, dermcidin, S100A7/psoriasin(More)
In recent years many solution approaches for different school timetabling problems (TTP) have been tried, among them tabu search, simulated annealing, genetic algorithms, and constraint programming [8]. However, most of the solution methods developed so far have been tested by means of only few (mostly only a handful) problem instances [6]. Further, until(More)
