We study quantum states produced by optimal phase covariant quantum cloners. We argue that cloned quantum superpositions are not macroscopic superpositions in the spirit of Schrödinger's cat, despite their large particle number. This is indicated by calculating several measures for macroscopic superpositions from the literature, as well as by investigating the distinguishability of the two supe...

Regulation of Cloned Cardiac Channels. (August 2005) Bharathi Balasubramanian, B.E., Madras University Co-Chairs of Advisory Committee: Dr. Charles S. Lessard Dr. Michael J. Davis Activation of a5ß1 integrin potentiates L-type calcium current in vascular smooth muscle, which is partly mediated by tyrosine phoshorylation of the a1c channel subunit. Expressed rabbit VSM and neuronal isoforms are ...

Somatic cell nuclear transfer (SCNT or cloning) returns a differentiated cell to a totipotent status; a process termed nuclear reprogramming. Reproductive cloning has potential applications in both agriculture and biomedicine, but is limited by low efficiency. To understand the deficiencies of nuclear reprogramming, our research has focused on both candidate genes and global gene expression pat...

Background: At the outset of the somatic cell nuclear transfer (SCNT) process, the chromatin structure of the somatic cell which governs its state of differentiation undergoes dramatic changes, called reprogramming, and is compelled back to the embryonic stage. However, the overall epigenetic makeup of the resultant cloned embryos has been acknowledged far different from the fertilized embryos....

NBS-LRR-type disease resistance gene-like cDNA, induced by salicylic acid (SA) was cloned from rye Secalecereale L. (2n = 14RR) var. Petkus, which has rust genes such as Lr26, Sr31 andRr9. We designed primers based on the NBS region and performed PCR using Petkus genomic DNA a template. Next, we TA-cloned 532-bp fragment containing five homologous amino sequences in region. The SA-treated showe...
