The main aim of this study was to develop and implement an algorithm for the rapid, accurate and automated identification of paths leading from buried protein clefts, pockets and cavities in dynamic and static protein structures to the outside solvent. The algorithm to perform a skeleton search was based on a reciprocal distance function grid that was(More)
We have developed an algorithm, "MOLE," for the rapid, fully automated location and characterization of molecular channels, tunnels, and pores. This algorithm has been made freely available on the Internet ( and overcomes many of the shortcomings and limitations of the recently developed CAVER software. The core of our MOLE(More)
Sarcoidosis is a granulomatous disorder showing a clear association with MHC (HLA) class I and class II genes. In order to investigate whether polymorphisms of nearby pro-inflammatory genes located within the MHC class III region may also contribute to susceptibility to sarcoidosis or to its clinical manifestation, tumour necrosis factor-alpha (TNF-alpha)(More)
Chronic obstructive pulmonary disease (COPD) is characterised by irreversible airflow limitation associated with chronic inflammation. Matrix metalloproteinases (MMPs) are proteolytic enzymes that contribute to the inflammatory response in COPD and degrade extracellular matrix components. Their enzymatic activity is inhibited by a four-member family of(More)
Aberrant neurodevelopment contributes to the etiology of schizophrenia. This study aimed to investigate the potential association of netrin G1 (NTNG1) rs628117 and brain-derived neurotrophic factor (BDNF) Val66Met (rs6265) genetic polymorphisms with susceptibility to schizophrenia. One hundred three Armenian patients with schizophrenia and 105 healthy(More)
In the recent genome-wide association study the polymorphisms of annexin A11 (ANXA11) gene were associated with susceptibility to sarcoidosis. Beside the replication of this finding and analysis of local ANXA11 expression in bronchoalveolar lavage cells, we wondered whether 'leading' ANXA11 rs1049550 (R230C) variant might also be related to the clinical(More)
Prosthetic joint infection (PJI) is a severe complication of total joint arthroplasty (TJA). We conducted a genetic association study that investigated whether selected coding variants of the genes for Toll-like receptors (TLR)2 and TLR4 may contribute to genetic susceptibility for PJI. In total, 350 patients with TJA (98 with PJI/252 without PJI), and 189(More)
Members of the interleukin-1 (IL-1) family are implicated in the pathogenesis of sarcoidosis and idiopathic pulmonary fibrosis (IPF). We have, therefore, performed a case-control study to investigate a plausible association between sarcoidosis and the polymorphisms in the IL-1alpha, IL-1beta, and IL-1 receptor antagonist (IL-1Ra) genes. Further, as a(More)
The chemokines RANTES (regulated on activation, T-cell expressed and secreted; CC chemokine ligand (CCL)-5) and monocyte inflammatory protein (MIP)-1alpha (CCL-3) have been implicated in the development of alveolitis in pulmonary sarcoidosis. The novel C chemokine single cysteine motif (SCM)-1alpha (XCL-1) and the CC chemokine monocyte chemoattractant(More)
For accuracy of quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR), normalisation with suitable reference genes is required. To date, no reference genes have been validated for expression studies of bronchoalveolar (BAL) cells. The aims of this study were to identify gene(s) with stable mRNA expression in BAL cells irrespective of(More)
