This article deals with two of the major steps involved in phospholipid synthesis: the preparation of the optically pure precursors, sn-glycero-3-phosphocholine (GPC) and -ethanolamine, from a convenient lipid source such as egg yolk, and acylation of hydroxyl groups present in those precursors involving an acid to yield the corresponding phospholipid. Phosphatidylcholines and phosphatidylethan...

The Spanish writing system has consistent grapheme-to-phoneme correspondences (GPC), rendering it more transparent than English. We compared first-language (L1) orthographic transparency on how monolingual Englishand Spanish-readers learned a novel writing system with a 1:1 (LT) and a 1:2 (LO) GPC. Our dependent variables were learning time, decoding, and vocabulary. We found a main effect for ...

Model based predictive control (MBPC) has attracted much attention since the 1990s (see, for example, Garcia et al. (1989) and Richalet (1993)). The early MBPC algorithms, such as MAC (Richalet et al. 1978), DMC (Cutler and Ramaker 1980), EHAC (Ydstie 1984) and GPC (Clarke et al. 1987), are mainly based on input/ output models. Each has a few di€ erent features which distinguish it from the oth...

PURPOSE The identification of the phosphodiester (PDE) (31)P MR signals in the healthy human breast at ultra-high field. METHODS In vivo (31)P MRS measurements at 7 T of the PDE signals in the breast were performed investigating the chemical shifts, the transverse- and the longitudinal relaxation times. Chemical shifts and transverse relaxation times were compared with non-ambiguous PDE signa...

Electrochemical behavior of a new class of glass-polymer composites (GPC), consisting of (100-x) ~01% (0.56LizS~0.19B~S,.0.25LiI) glass and x ~01% (P(E0)6.LiN(CF$O&) polymer with x = 7, 13 and 25, has been investigated in cells with different electrodes. Results show that the addition of the polymer to the glass powder increases not only the mechanical flexibility but also the ionic conductivit...

Abstract: Methods of fault-hardening software implementations of the numerical Model Predictive Control (MPC) algorithms are discussed in the paper. In particular, Generalized Predictive Control (GPC) algorithms are considered. The robustness of these algorithms with respect to faults is crucial for process safety and economic efficiency, as faults may result in major control performance degrad...

The α7 acetylcholine nicotinic receptor (α7) is an important mediator of cholinergic transmission during brain development. Here we present an intracellular signaling mechanism for the α7 receptor. Proteomic analysis of immunoprecipitated α7 subunits reveals an interaction with a G protein pathway complex (GPC) comprising Gα(i/o), GAP-43 and G protein regulated inducer of neurite outgrowth 1 (G...

We report an on-line coupling of gel permeation chromatography (GPC) to Fourier transform mass spectrometry (FTMS) using a modified commercial electrospray ionization (ESI) interface. Selected oligomer profiles for the sodiated (1+ through 5+ charge states) oligomer ions of a narrow-molecular-weight poly(methyl methacrylate) were generated and used for obtaining a calibration curve. Using the M...

Introduction: We recently reported that the concentrations of both glycerolphosphocholine (GPC) and phosphocholine (PC) were higher in biopsies from non-enhancing Grade 3 astrocytoma (AS3) versus Grade 2 astrocytomas (AS2). During that study, we noted that the relative size of the GPC peak in the 1D high-resolution magic angle spinning (HRMAS) spectrum was higher than the PC peak in all cases i...

GYPC encodes two erythrocyte surface sialoglycoproteins in humans, glycophorin C and glycophorin D (GPC and GPD), via initiation of translation at two start codons on a single transcript. The malaria-causing parasite Plasmodium falciparum uses GPC as a means of invasion into the human red blood cell. Here, we examine the molecular evolution of GYPC among the Hominoidea (Greater and Lesser Apes)...
