Matrix Gla protein (MGP) is a crucial inhibitor of vessel and cartilage calcification. We investigated the association of T-138C MGP promoter polymorphism with the degree of atherosclerosis, vascular calcification and patients' clinical background including calcification of the trachea and costal cartilage. Analysis of 108 autopsy cases was carried out by polymorphism-specific PCR on formalin-f...

AIM To evaluate the high sensitivity C-reactive protein (hsCRP), Fetuin-A and matrix γ-carboxyglutamate protein (MGP) as the main factors for vascular calcification and inflammation in serum of patients with advanced age-related macular degeneration (ARMD) in comparison to healthy controls. METHODS The subjects were 40 patients with choroidal neovascularization (CNV) having a mean age of 70.9...

The U.S. Environmental Protection Agency's (U.S. EPA) narcosis model requires the measurement of 18 parent and 16 groups of alkyl polycyclic aromatic hydrocarbons (PAHs) (so-called 34 PAHs) in sediments to calculate the number of PAH toxic units (TU) available to benthic organisms. If data for the 34 PAHs are not available, the U.S. EPA proposes estimating the risk by multiplying the TU for 13 ...

OBJECTIVES The purpose of this study is to report a case of a plexiform neurofibroma (PNF) in the pelvic region treated with sweet bee venom (SBV) and mountain ginseng pharmacopuncture (MGP). METHODS A 16-year-old girl was diagnosed as having PNFs, neurofibromatosis type 1, 10 years ago and she had surgery three times to remove the benign tumors, but the growth of the PNFs continued. She has ...

BACKGROUND Matrix Gla protein (MGP) is known to act as a potent local inhibitor of vascular calcifications. However, in order to be active, MGP must be phosphorylated and carboxylated, with this last process being dependent on vitamin K. The present study focused on the inactive form of MGP (dephosphorylated and uncarboxylated: dp-ucMGP) in a population of hemodialyzed (HD) patients. Results fo...

The present studies demonstrate that matrix Gla protein (MGP), a 10-kDa vitamin K-dependent protein, is phosphorylated at 3 serine residues near its N-terminus. Phosphoserine was identified at residues 3, 6, and 9 of bovine, human, rat, and lamb MGP by N-terminal protein sequencing. All 3 modified serines are in tandemly repeated Ser-X-Glu sequences. Two of the serines phosphorylated in shark M...

PURPOSE To test the ability of promoter fragments from the matrix Gla protein (MGP) and vascular endothelial-cadherin (VE-cad) genes to target gene expression in a specific manner in the cells of the outflow pathway, by using adenoviral-mediated gene transfer in organ culture. METHODS Perfused anterior segments of human eyes were infected with replication-deficient recombinant adenoviruses ex...

This paper deals with control of bulking by chlorination in a laboratory-scale (15l/ d) biological nutrient removal system. Bulking was caused by filamentous organisms characteristic of nutrient removal systems, i.e. Type 0092, Microthrix parvicella and Type 0914. Over a continuous dosing period of 19 d, at 8 mgCl2 /gMLSS.d the diluted sludge volume index (DSVI) decreased from 230 to 48 ml/g. N...

With the ability to reveal the macroscopic properties of correlated electron systems, Determinant Quantum Monte Carlo (DQMC) simulations is a popular method in condense matter physics. Studies of emerging complex materials eagerly demand more computational powers to carry out the simulations. However, parallelization of the DQMC simulation is extremely challenging, owing to the serial nature of...

The cellular and molecular events leading to calcification in atherosclerotic lesions are unknown. We and others have shown that bone-associated proteins, particularly matrix Gla protein (MGP) and osteopontin (OP), can be detected in atherosclerotic lesions, thus suggesting an active calcification process. In the present study, we aimed to determine whether human vascular smooth muscle cells (V...
