Neutrophils are indispensable for clearing infections with the prominent human pathogen Staphylococcus aureus. Here, we report that S. aureus secretes a family of proteins that potently inhibits the activity of neutrophil serine proteases (NSPs): neutrophil elastase (NE), proteinase 3, and cathepsin G. The NSPs, but not related serine proteases, are specifically blocked by the extracellular adh...

The most important issue that must be solved in designing a data gathering algorithm for wireless sensor networks (WSNS) is how to save sensor node energy while meeting the needs of applications/users. In this paper, we propose a novel energy-aware routing protocol (EAP) for a long-lived sensor network. EAP achieves a good performance in terms of lifetime by minimizing energy consumption for in...

The present study aimed to assess the target and present reading comprehension needs and abilities of Iranian medical students with different levels of English language proficiency. A total of 283 medical students and 23 ESP instructors were chosen through cluster sampling. The data collection instruments included the Persian version of Atai and Nazari’s (2011) needs analysis questionnaire and ...

The aim of the present study was to examine the relationship between spelling knowledge and reading skills among a group of 16 intermediate-level Arab learners of English as a second language (ESL) and a corresponding comparison group of 21 intermediate-level ESL learners in an English for academic purposes (EAP) program. A spelling task was used to assess the English orthographic or spelling k...

This is an EAP Syllabus Design in the context of CAI (Computer Assisted Instruction) in a specific area: School of Foreign Languages and Cultures, Beijing Wuzi University. EAP writing used to be considered cautious, serious, and uninteresting. In order to design an attractive and efficient syllabus for EAP course in the chosen context, CAI auxiliary teaching method, which has been recommended a...

Extracellular adherence protein Eap secreted from Staphylococcus aureus was previously found to enhance the adherence of S. aureus to eukaryotic cells. This enhancement effect is due to the ability of Eap to rebind to S. aureus and to bind to eukaryotic cells and several plasma and matrix proteins. In this study we defined one potential binding target for Eap on the surface of S. aureus, a surf...

BACKGROUND In Diffusion Tensor Imaging (DTI), Riemannian framework based on Information Geometry theory has been proposed for processing tensors on estimation, interpolation, smoothing, regularization, segmentation, statistical test and so on. Recently Riemannian framework has been generalized to Orientation Distribution Function (ODF) and it is applicable to any Probability Density Function (P...

in this study, van dijk’s (1998) model of cda was utilized in order to examine the representation of iran’s nuclear program in editorials published by british news casting companies. the analysis of the editorials was carried out at two levels of headlines and full text stories with regard to the linguistic features of lexical choices, nominalization, passivization, overcompleteness, and voice....
