In an attempt to distinguish between the UDP-glucose: flavonol 3-O-glucosyltransferase (3G T ) and the UDP-glucose:anthocyanidin 3-O-glucosyltransferase in flower buds o f Petunia hybrida, several properties of these activities were determined. The 3-glucosylation o f anthocyanidin had a pH-activity optimum of 7.2, that o f flavonol pH 9.2 to 9.5. Anthocyanidin 3G T activity was lowered in the ...

Beta-amyloid protein (Abeta), a major protein component of brain senile plaques in Alzheimer’s disease, is known to be directly responsible for the production of reactive oxygen species (ROS) and induction of apoptosis. In this study, the protective effect of cyanidin 3-O-glucopyranoside (Cy-3G), an anthocyanin derivate purified from fruits, on Abeta-induced rat pheochromocytoma (PC12) cultures...

In this paper we describe the approved DO Upgrade detector, and its physics capabilities. The DO Upgrade is under construction and will run during the next Fermilab collider running period in early 1999 (R un II). The upgrade is designed to work at the higher luminosities and shorter bunch spacings expected during this run. The major elements of the upgrade are: a new tracking system with a sil...

Differentiation-inducing factor-3 (DIF-3), found in the cellular slime mold Dictyostelium discoideum, and its derivatives, such as butoxy-DIF-3 (Bu-DIF-3), are potent anti-tumor agents. To investigate the activity of DIF-like molecules in tumor cells, we recently synthesized a green fluorescent DIF-3 derivative, BODIPY-DIF-3G, and analyzed its bioactivity and cellular localization. In this stud...

While there has been a great deal of excitement in view of m-commerce, very little is actually known about conditions and critical success factors for successful introduction of the 3 generation mobile network services here in Malaysia. This study investigates the factors for successful diffusion of 3G network services and their role in advancing an interactive marketplace. 3G which simply mean...

This paper presents the Cellular Network Vulnerability Assessment Toolkit CAT, designed for end-to-end vulnerability assessment of 3G networks. It is the first tool of its kind to model and represent 3G network vulnerabilities and attacks as attack graphs. CAT uses freely available 3G telecommunication specifications written in SDL, the standard Specification and Description Language to produce...

Standardization of 3 Generation (3G) mobile communication systems has produced the first specification releases and the commercial deployment of the 3G systems has started. Whereas 1G and 2G focused on efficiently providing voice services, in 3G a lot of attention has been devoted to solutions that support both Circuit Switched (CS) and Packet Switched (PS) communication. That has called for ve...

As the use of Instant message service increased, emoticons also have been changed and developed in various forms. Especially, 3rd-generation (3G) emoticons are being spotlighted as new communicative tools because they provide wide selection of choice through vividly personified characters. To reflect this trend, this study formulated and confirmed a hypothesis that the more emoticons are person...

3G which simply means 3 generation mobile communications technology has been widely discussed by many telecommunications service providers. It was launched by ITU (International Telecommunication Union) about 13 years ago. However, the adoption of this technology, perception of adoption and the true success of it in Malaysia could be somewhat over optimistic given the scenario in other nations ...
