background and aims. in contrast to prepared natural dentin abutments, little is known concerning factors influencing the retention of fixed prostheses cemented to implant abutments. the aim of this study was to investigate the effect of implant abutment height on the retention of single castings cemented to wide and narrow platform implant abutments. materials and methods. thirty-six parallel-...
To understand nonylphenol (NP) contamination in the northeast coastal environment in China, NP was determined in 19 sediment and 20 bivalve samples collected during November 2005. NP was identified in all sediment samples in the range of 8.8 to 1.0 x 10(3) ng/g dw (dry weight), with an average of 0.12 x 10(3) ng/g dw. Most of the bivalve samples (oysters and mussels) contained detectable amount...
This paper deals with syzygies of the ideals of the Veronese embeddings. By Green’s Theorem we know that OPn(d) satisfies Green-Lazarsfeld’s Property Np ∀d ≥ p, ∀n. By Ottaviani-Paoletti’s theorem if n ≥ 2, d ≥ 3 and 3d − 2 ≤ p then OPn(d) does not satisfy Property Np. The cases n ≥ 3, d ≥ 3, d < p < 3d− 2 are still open (except n = d = 3). Here we deal with one of these cases, namely we prove ...
Huntington's disease (HD) is a progressive neurodegenerative disorder characterized by chorea, psychiatric disturbances, and dementia. The striatum is the primary site of neuronal loss in HD; however, neither the mechanism of neurodegeneration nor the underlying cause of the selectivity for the striatum is understood. Chronic systemic injection of 3-nitropropionic acid (3-NP) into rats induces ...
Niemann-Pick Type C (NP-C) disease, caused by mutations in either human NPC1 (hNPC1) or human NPC2 (hNPC2), is characterized by the accumulation of unesterified cholesterol in late endosomes. Although it is known that the NP-C proteins are targeted to late endosomal/lysosomal compartments, their delivery mechanisms have not been fully elucidated. To identify mechanisms regulating NP-C protein l...
We have examined three 131I-labeled murine monoclonal antibodies (MAbs) against carcinoembryonic antigen (CEA), NP-2, NP-3, and NP-4, after i.v. injection in patients with diverse cancers. Although the MAbs had a similar tumor-targeting ability, several important features were discovered that have led us to the selection of one of these MAbs for further clinical evaluation. We found that it is ...
Huntingtons disease (HD) is an autosomal dominant neurodegenerative disease. Accordingly, 3-nitropropionic acid (3-NP) has been found to effectively produce HD-like symptoms. Amaranthus viridis Linn (HAEAV), popularly known in Chauraiya Hindi, may act as a neuroprotective agent vitro andin vivo. We evaluated the hypothesis that hydro-ethanolic extract of could prevent behavioral and oxidative a...
BACKGROUND Huntington's disease (HD) is a neurodegenerative syndrome that leads to marked decline in cognitive functioning along with uncharacteristic body movements called chorea. There exists no therapeutic agent to address the disease.3-Nitropropionic acid (3-NP) which is a suicide inhibitor of succinate dehydrogenase and a well-known experimental model to study Huntington's disease, causes ...
