Plasma homocysteine (Hcy) is an independent vascular risk factor. Its remethylation to methionine is regulated by the activity of the enzyme 5,10-methylene tetrahydrofolate reductase (MTHFR). A C-to-T substitution at nucleotide 677 of the MTHFR gene is frequently associated to hyperhomocysteinemia. In this study, we evaluated the relationship among MTHFR(More)
Connections between inflammatory rheumatic diseases and plasmacellular dyscrasias are still discussed. The observation of non-secretory IgA k myeloma occurred in a patient suffering by ankylosing spondylitis has induced us to do some considerations about the possible connections between these diseases and to stress the rarity of such association never(More)
BACKGROUND AND AIMS The relationships between very high plasma HDLc and subclinical atherosclerosis are still a matter of debate. METHODS AND RESULTS Twenty subjects with primary hyperalphalipoproteinemia (HAL, with HDLc in the highest 10th percentile and absence of overt secondary causes of this condition), aged 30-65 years, were compared with 20 age and(More)
The problem of tracking the position and attitude of an autonomous underwater vehicle (AUV) in the horizontal plane, under the presence of ocean current disturbances is discussed. The effect of the gradual variation of the parameters is taken into account, saturation of rudders is examined, and a condition under which saturation will not occur is derived by(More)
The way we collect, store, and share dental records of our patients is rapidly becoming digital. Many programs have been designed to run on a single computer or local network to handle various tasks, so selecting a system can be complex; it can require high acquisition costs, update fees, and installation difficulties. The purpose of this article is to(More)
In this study, the procedure of sintering and heat treatment of Al2O3-SiC-MgO nanoceramic was considered. For improving the densification behavior and mechanical properties, experimental variables, such as sintering temperature and duration, which significantly influence the fracture performance of this nanocomposite body, were optimized. To obtain desired(More)
Improving fracture performance and sintering procedure of alumina/silicon carbide nano ceramic is considered. To do this, some experimental variables such as sintering conditions and silicon carbide volume fraction were optimized. In this study, several tests were conducted on the nano ceramic samples which prepared in different conditions to achieve the(More)
