The airways of cystic fibrosis (CF) patients are characterised by neutrophils that release high amounts of elastase overwhelming the local antiprotease shield. Inhalation of alpha(1)-antitrypsin (AAT) may restore the protease-antiprotease balance and attenuate airway inflammation in CF airways. The aims of the present study were: 1) to assess the best(More)
BACKGROUND The urokinase plasminogen activator (uPA) system is one of the best-investigated protease systems, both under physiological and pathological conditions, including various types of cancer. However, effects of co-expression of members of the uPA system in soft-tissue sarcoma (STS) patients at the protein level in both tumour tissue and serum have(More)
BACKGROUND A light-porous-particle, dry-powder formulation of tobramycin was developed, using PulmoSphere® technology, to improve airway delivery efficiency, substantially reduce delivery time, and improve patient convenience and satisfaction. We evaluated the safety, efficacy and convenience of tobramycin inhalation powder (TIP™) versus tobramycin(More)
BACKGROUND Pseudomonas aeruginosa infection determines the course of cystic fibrosis (CF) lung disease. Studies in human peripheral blood indicate that P aeruginosa infection is associated with a predominant T(H)2 immune response, whereas T(H)1 responses are accompanied by a better pulmonary outcome. OBJECTIVE Analyses of peripheral blood may not(More)
The product of the HDMX (or MDM4) gene is structurally related to the MDM2 oncoprotein and is also capable of interacting with the tumor suppressor protein p53. The aim of our study was to determine the amplification status of the HDMX gene and the expression of the HDMX mRNA (particularly that of the HDMX-S splice variant) in soft-tissue sarcomas (STS).(More)
Autosomal-recessive congenital sodium diarrhea (CSD) is characterized by perinatal onset of a persistent watery diarrhea with nonproportionally high fecal sodium excretion. Defective jejunal brush-border Na(+)/H(+) exchange has been reported in three sporadic patients, but the molecular basis of the disease has not been elucidated. We reviewed data from a(More)
Self-renewal is considered as a common property of stem cells. Dysregulation of stem cell self-renewal is likely a requirement for the development of cancer. Hiwi, the human Piwi gene, encodes a protein responsible for stem cell self-renewal. In this study, we investigated the expression of Hiwi at the RNA level by real-time quantitative PCR in 65 primary(More)
Cystic fibrosis (CF) lung disease is characterized by infection with Pseudomonas aeruginosa and a sustained accumulation of neutrophils. In this study, we analyzed 1) the expression of MyD88-dependent TLRs on circulating and airway neutrophils in P. aeruginosa-infected CF patients, P. aeruginosa-infected non-CF bronchiectasis patients, and noninfected(More)
BACKGROUND Survivin, the smallest member of the inhibitor of apoptosis protein (IAP) family, is a bifunctional protein that has been implicated in both control of cell division and inhibition of apoptosis. MATERIAL AND METHODS This review specially focuses on clinical and experimental data on the relevance of survivin in radiooncology and its role as a(More)
Survivin, a member of the inhibitor-of-apoptosis family is an essential protein for regular mitosis and is involved in an anti-apoptotic pathway. In some studies, an association between survivin expression and radiosensitivity has been described for tumor cells, but the relationship between p53 and survivin regarding radioresistance remains to be clarified.(More)
