araoxonase (PON) is a serum esterase, associated with HDL-C. It decreases the oxidation of LDL-C. Serum PON1 activity has been shown to diminish in several diseases. We investigated the serum PON1 activity and lipid profiles in diabetic and non-diabetic end stage renal disease (ESRD) patients and controls as well as serum PON1 activity pre and post dialysis. Materials and Methods: For this stud...

We examined the flows of nitrogen in two batch incubations of plankton assemblages under controlled conditions, using mesopelagic seawater from different depths. Observations included concentrations of nutrients, organic matter (particulate and dissolved) and plankton (biomass by species). Because nitrogen flows were not observed directly (as is generally the case), we examined them using a mul...

Abstract This paper presents on the design and analysis of Dense Wavelength Division Multiplexing Passive Optical Network (DWDM-PON) which is upcoming trend technology nowadays to transmit up 40 Gbps data. Various modulation techniques such as Non-Return Zero (NRZ), Return-Zero (RZ) duo binary coding are simulated in this DWDM-PON. Using OptiSystem software, DWDM-PON designed for 32 channels wi...

Paraoxonase 1 (PON1) is thought to influence serum homocysteine concentrations, at least in part, due to its homocysteine thiolactonase activity and to play a role in preeclampsia and atherosclerosis. We investigated the effects of PON 55 and PON 192 polymorphisms on plasma total homocysteine (tHcy) concentrations in preeclamptic and healthy pregnants among Turkish population (N = 106). PON 55 ...

In dividing Drosophila sensory organ precursor (SOP) cells, the fate determinant Numb and its associated adaptor protein Pon localize asymmetrically and segregate into the anterior daughter cell, where Numb influences cell fate by repressing Notch signaling. Asymmetric localization of both proteins requires the protein kinase aPKC and its substrate Lethal (2) giant larvae (Lgl). Because both Nu...

Paraoxonase, an enzyme associated with high-density lipoprotein (HDL-PON), exerts a protective effect against oxidative damage of circulating cells and lipoproteins, modulates the susceptibility of HDL to atherogenic modifications such as glycation and homocysteinylation, and even exerts an antiinflammatory role. The aim of the present study was to investigate the relationship between lipoprote...

Human serum paraoxonase (PON) associated with high density lipoprotein (HDL) , has been postulated to have a role in protecting low-density lipoprotein (LDL) against oxidative damage, which has led to the proposal that PON is an anti-atherogenic and anti-inflammatory enzyme. It has genetic polymorphism at the 191 (R ->Q) and two alloenzymes A and B and three phenotypes A, B, and AB. We exa...

This paper reviews the standardization work that has been done in question 2 of ITU-T study group 15, which is the lead group on optical access transport technology. The major topics covered are the progress in the G-PON series and the new point-to-point fiber access recommendation. Finally, a brief view of the future plan of XG-PON is presented. key words: ITU-T, optical, fiber, PON, access

We propose a bidirectional wavelength division multiplexing passive optical network (WDM-PON) based on a reflective semiconductor optical amplifier (RSOA) by employing a differential quadrature phase shift keying (DQPSK) signal for down-link and an on-off keying (OOK) re-modulated signal for up-link over 45km SMF colorless WDM-PON without dispersion compensation was demonstrated for both 10 Gbi...

BACKGROUND Coronary vein graft disease is an important contributor to the morbidity after coronary artery bypass grafting (CABG). Late occlusion of the graft is a serious complication that limits the use of the saphenous vein as a coronary bypass conduit. It is frequently encountered in old, degenerated vein grafts with advanced atherosclerotic plaque formation. Paraoxonase-1 (PON-1) is an HDL-...
