BACKGROUND The transporter associated with antigen processing (TAP) is a critical component of the major histocompatibility complex (MHC) class I antigen processing and presentation pathway. TAP transports antigenic peptides into the endoplasmic reticulum where it loads them into the binding groove of MHC class I molecules. Because peptides must first be transported by TAP in order to be presen...

BACKGROUND Variability of body weight (BW) and height calls for indexation of volumetric hemodynamic parameters. Extravascular lung water (EVLW) has formerly been indexed to actual BW (BW(act)) termed EVLW-index (EVLWI). In overweight patients indexation to BW(act) might inappropriately lower indexed EVLWI(act). Several studies suggest indexation of EVLWI to predicted BW (EVLWI(pred)). However,...

We have developed a web-server for predicting the folding rate of a protein based on its amino acid sequence information alone. The webserver is called Pred-PFR (Predicting Protein Folding Rate). Pred-PFR is featured by fusing multiple individual predictors, each of which is established based on one special feature derived from the protein sequence. The ensemble predictor thus formed is superio...

[Purpose] The aim of the present study was to establish up-to-date data regarding the lung function of cystic fibrosis (CF) patients. [Subjects and Methods] Forty-eight patients of both genders, with a diagnosis of CF, were recruited. As a result our sample presented, according to the GOLD criteria, 23 patients with mild lung obstruction (FEV1%pred: 89.86), 16 patients with moderate lung obstru...

Chierchia 1998 proposes that languages vary in terms of what they allow their NPs to denote. This variation is encoded in a semantic parameter which determines whether NPs denote names of kinds (and are therefore argumental) [+arg, -pred], predicates (and therefore require a determiner to be in an argument position) [-arg, +pred] or either [+arg, +pred]. In this paper we argue using data from b...

We present a novel method that predicts transmembrane domains in proteins using solely information contained in the sequence itself. The PRED-TMR algorithm described, refines a standard hydrophobicity analysis with a detection of potential termini ('edges', starts and ends) of transmembrane regions. This allows one both to discard highly hydrophobic regions not delimited by clear start and end ...

The vast cell-surface receptor family of G-protein coupled receptors (GPCRs) is the focus of both academic and pharmaceutical research due to their key role in cell physiology along with their amenability to drug intervention. As the data flow rate from the various genome and proteome projects continues to grow, so does the need for fast, automated and reliable screening for new members of the ...

The bronchodilator response (BDR) in forced expiratory volume in one second (FEV1) is routinely assessed to estimate the reversibility of airways obstruction. However, there is no consensus on how the BDR should be expressed, and recommendations applying to children are lacking. Similarly, the relationship between BDR and nonspecific bronchial hyperresponsiveness to histamine (BHR) has not been...

Proper modeling of nonspecific salt-mediated electrostatic interactions is essential to understanding the binding of charged ligands to nucleic acids. Because the linear Poisson-Boltzmann equation (PBE) and the more approximate generalized Born approach are applied routinely to nucleic acids and their interactions with charged ligands, the reliability of these methods is examined vis-à-vis an e...

A 66-yr-old female presented with dyspnoea on exercise, severe cough, purulent sputum and intermittent chest pain under both costal arches for the last 14 days. Five months prior to admission, pulmonary tuberculosis of both lower lobes had been diagnosed microscopically as the cause of recurrent bilateral pleural and pericardial effusions and pericardial thickening, and the patient was still un...
