Modified Broadband Ruthroff-Type Transmission Line Transformer Balun for Isolation-Enhanced Passive Mixer Design
Published 2024-02-01“…Generalized broadband operation facilitates multifunction or multiband highly integrated applications, such as modern transceiver systems, where ultra-wideband bidirectional passive mixers are favored to avoid a complex up/down-conversion scheme. In this paper, a modified Ruthroff-type transmission line transformer (TLT) balun is presented to enhance the isolation of the mixer from the local oscillator (LO) to the radio frequency (RF). …”

Epigenetic modification of the frataxin gene for the treatment of Friedreich’s ataxia
Published 2018“…</p> <p>In this thesis, first HDAC3 and G9a were targeted by siRNA-mediated knockdown to increase overall acetylation and reduce methylation and promote transcription of FXN. Using a human FXN-GAA-Luciferase (FXN-GAA-Luc) repeat expansion reporter model of FRDA, HDAC3 knock-down was shown to increase FXN mRNA levels with no effect on protein, while G9a knock-down did not show an effect on either FXN mRNA or protein levels. …”

Dysregulation of multiple facets of glycogen metabolism in a murine model of Pompe disease.
Published 2013-01-01“…Lysosomal glycogen storage also correlated with a dysregulation of phosphorylase, which normally breaks down cytoplasmic glycogen. Analysis of phosphorylase activity confirmed a previous report that, although phosphorylase protein levels are identical in muscle lysates from wild type and GAA(-/-) mice, phosphorylase activity is suppressed in the GAA(-/-) mice in the absence of AMP. …”
