This study investigated the roles of sucrose synthase (SUS) in developing seeds and siliques of Arabidopsis thaliana. Enzyme activity assays showed that SUS activity was highest in developing whole siliques and young rosette leaves compared with other tissues including mature leaves, stems, and flowers. Surprisingly, quantitative PCR analyses revealed little correlation between SUS activity and...

TAS-103, a new anticancer drug, induces DNA cleavage by inhibiting the activities of topoisomerases I and II. We investigated the mechanism of TAS-103-induced apoptosis in human cell lines. Pulsed field gel electrophoresis revealed that in the leukemia cell line HL-60 and the H(2)O(2)-resistant subclone, HP100, TAS-103 induced DNA cleavage to form 1-2-Mb fragments at 1 h to a similar extent, in...

OBJECTIVE Type 1 diabetes is associated with a high risk of coronary heart disease (CHD), despite the absence of dyslipidemia. Oxidative modification may render LDLs more atherogenic. We aimed to assess antioxidant status in type 1 diabetes and its association with coronary artery calcification (CAC). RESEARCH DESIGN AND METHODS Total antioxidant status (TAS) of serum was measured using the T...

Teaching Assistants (TAs) play an important role in supporting research-based instructional environments, yet the connection between TAs' pedagogical beliefs and instructional practices is not well understood. We build upon a broad foundation of research on the nature of pedagogical content knowledge to develop an analytic framework for characterizing how physics TAs both describe and enact the...

In this correspondence we presents the performance analysis of multiple-input multiple-output (MIMO) technique incorporating maximal-ratio combining with transmit antenna selection (MRC/TAS) in frequency-flat Rayleigh fading channels. The expression of probability density function (pdf) for MRC/TAS (Nt , 1; Nr) scheme has been derived. The probability of outage is examined first. Further by the...

IJSER © 2017 http://www.ijser.org Abstract—In this paper, we analyze the combined performance of joint transmit and receive antenna selection (JTRAS), transmit antenna selection/maximum ratio combining (TAS/MRC) and transmit antenna selection/receiver antenna selection (TAS/RAS) approach in the context of physical layer security (PLS) in multiple-input multiple-output (MIMO) wiretap channels. W...

In future 5G communication system, radio resources can be effectively reused by cognitive radio networks (CRNs), where a lot of secondary users (SUs) are able to access the spectrum of primary users (PUs). In this paper, we analyze the optimal spectrum access and power control of SUs on multiple bands with the target of maximizing the average sum rate (ASR) of SUs. Specifically, based on the st...

Sucrose synthase (SUS) is phosphorylated on a major, amino-terminal site located at Ser-15 (S15) in the maize (Zea mays) SUS1 protein. Site- and phospho-specific antibodies against a phosphorylated S15 (pS15) peptide allowed direct analysis of S15 phosphorylation in relation to membrane association. Immunoblots of the maize leaf elongation zone, divided into 4-cm segments, demonstrated that the...
