background and aims. orientation of the occlusal plane is one of the most important clinical procedures in prosthodontic rehabilitation of edentulous patients. the aim of this study was to define the best posterior reference point of ala-tragus line for orientation of occlusal plane for complete denture fabrication. materials and methods. fifty-three dental students (27 females and 26 males) wi...

Chronic bacteriuria is a common occurrence among spinal-cord injury patients and others with neuropathic bladders. If bacteria are present in the urinary tract, the patient may develop symptoms of infection or remain asymptomatic. We have compared virulence properties of 28 Escherichia coli isolates from patients with symptomatic urinary tract infections (UTI) and 29 E. coli isolates from patie...

The Technology Readiness Index (TRI) developed by Parasuraman (2000) was adapted to measure the technology readiness of public school teachers in Abu Dhabi, United Arab Emirates. The study aims at better understanding the factors (mostly demographics) that affect such readiness levels. In addition, Abu Dhabi teachers are segmented into five main groups, with the highest percentage being “laggar...

Data replication is a common method used to improve the performance of data access in distributed systems. In this paper, two dynamic replication algorithms, Simple Bottom-Up (SBU) and Aggregate Bottom-Up (ABU), are proposed for the multitier Data Grid. A multi-tier Data Grid simulator called DRepSim is developed for studying the performances of the dynamic replication algorithms. The simulatio...

Objective(s): To investigate the association of single nucleotide polymorphisms (SNPs) in the peroxisome proliferator-activated receptors gamma (PPARG) with essential hypertension (EH) and additional role of gene– high-density lipoprotein cholesterol (HDL) interaction. Materials and Methods:A total of 1640 patients with EH (806 males, 834 females), with a mean age of 52.5±12.6 years, were selec...

introduction during the process photodynamic therapy (pdt), bleaching of photosensitizer induced by irradiation and generation of reactive oxygen species (ros) can provide some information concerning the efficiency of treatment. since gold nanoparticles (gnps) have been highlighted as efficient drug delivery systems, in this study, by utilizing gnps conjugated with 5 aminolevulinic acid (5-ala-...

The glycopeptide vancomycin has an antimicrobial effect by halting the synthesis of bacterial cell-wall binding D-Ala-D-Ala peptide motif precursor Lipid II. This interaction been extensively investigated using techniques such as XRD and NMR. Here, complexed with Ala-γGlu-Lys-D-Ala-D-Ala (the pentapeptide part II) is studied means Raman optical activity (ROA) spectroscopy. Where for conventiona...
