Aim: Upper gastrointestinal tract carcinomas are major health problem around the world. Esophageal cancer (EC) is usually diagnosed at an advanced stage; therefore most therapeutic approaches are palliative. The aim of the study was to investigate the possible relationship between serum activities of paraoxonase (PON1) and arylesterase (ARE), and clinicopathological characteristics in EC. Metho...

A Passive Optical Network (PON) is a network technology for deploying access networks based on passive optical components. In a single PON access network, the client terminals are connected to a Central Office through optical splitters and interconnecting fibers where each splitter splits in equal parts the input optical signal coming from the Central Office over its different output fibers. In...

activity in addition to the diseases which the authors stated [1] . The authors did not mention such contributing factors. In this regard, simple laboratory tests such as routine biochemistry tests, erythrocyte sedimentation rate and C-reactive protein could be carried out to exclude potential confounders. Also, dietary supplements such as vitamin C, vitamin E, iron, zinc and flavonoids can alt...

BACKGROUND Rheumatoid arthritis (RA) is the most common chronic inflammatory joint disease, with a worldwide prevalence of 0.5% to 1%. Anti-cyclic citrullinated peptide antibody (anti-CCP-2 Ab) is a marker of choice for diagnosing early and late RA. Anti-oxidant enzymes activity decreases in RA patients. Till now, the relationship between the rheumatoid factor (RF) and anti-CCP-2 Ab, anti-oxida...

A two dimensional spectral/spatial cyclic shift (2D-CS) optical code division multiple access (OCDMA) systems is proposed for a potentially next generation passive network (NG-PON) implementation called (2D-CS NG-OCDMA-PON) system. The2D-CS characterized by high capacity and zero cross correlation property leads to completely eliminating the interference (MAI) effect that considered as main OCD...

Introduction Our group has previously demonstrated that oxidized phospholipids in mildly oxidized LDL (MM-LDL) produced by oxidation with lipoxygenase, iron, or cocultures of artery wall cells increase monocyte-endothelial interactions and this sequence of events is blocked by HDL. To obtain further insight into the mechanism by which HDL abolishes the activity of MM-LDL we investigated the eff...

Introduction With the expansion of services offered over the Internet, the “last mile” bottleneck problems continue to exacerbate. Passive Optical Network (PON) is a technology viewed by many as an attractive solution to this problem [1,2]. There are several topologies suitable for the access network: tree, ring, or bus (Figure 1). All transmissions in a PON are performed between Optical Line T...

NG-PON systems present optical access infrastructures to support various applications of many service providers. Therefore, some general requirements for NG-PON networks are characterized and specified. The HPON network presents a necessary phase of the future transition from TDM to WDM multiplexing techniques utilized in passive optical networks. Requirements for the HPON are therefore also in...

OBJECTIVE During inflammation, the serum amyloid A (SAA) content of HDL increases, whereas apolipoprotein A-I (apoA-I) and paraoxonase-1 (PON-1) decrease. It remains unclear whether SAA physically displaces apoA-I or if these changes derive from coordinated but inverse transcriptional regulation of the HDL apolipoprotein genes. Because cytokines stimulate the hepatic expression of inflammatory ...

We presented review on current advancement in WDM-PON technologies to standarized economical system implementation, and also discuss cost-effective solutions and potential areas of application. Key-Words: WDM-PON, OFDM, OCDMA, RSOA.
