In this paper using strongly duplexes we introduce a new class of (semi)hypergroups. The associated (semi)hypergroup from a strongly duplex is called duplex (semi)hypergroup. Two computer programs written in MATLAB show that the two groups Z2n and Zn × Z2 produce a strongly duplex and its associated hypergroup is a complementary feasible hypergroup.

Synthesis of a neomycin-Hoechst 33258 conjugate is reported. The conjugate combines the ligands known to selectively bind in the duplex and the triplex groove. The conjugate stabilizes DNA duplex over DNA triplex. The conjugate selectively stabilizes the DNA duplex (in the presence of salt), with as little as 2 muM of the ligand leading to a DeltaTm of 25 degrees C.

We report a general method for screening, in solution, the impact of deviations from canonical Watson-Crick composition on the thermodynamic stability of nucleic acid duplexes. We demonstrate how fluorescence resonance energy transfer (FRET) can be used to detect directly free energy differences between an initially formed "reference" duplex (usually a Watson-Crick duplex) and a related "test" ...

RecA protein will bind to a gapped duplex DNA molecule and promote a DNA strand exchange with a second homologous linear duplex. A double-strand break in the second duplex is efficiently bypassed in the course of these reactions. We demonstrate that the bypass of double-strand breaks is not explained by a mechanism involving homologous interactions between two duplex DNA molecules, but instead ...

In this study, two new duplex PCR methods based on the groEL gene were developed and investigated for the diagnosis of rickettsiae. The first duplex PCR assay amplified the 229-bp and the 366-bp DNAs of 6 strains including typhus group (TG) and spotted fever group (SFG) rickettsiae, and 5 scrub typhus group (STG) rickettsiae, respectively. The second duplex PCR assay amplified the 397-bp and th...

Device-to-device (D2D) pairs are allowed to reuse the spectrum of cellular users who are in a good quality channel state with underlaying cellular network. However, cellular users usually suffer a poor performance in term of achievable rate when they are in a cell edge or in deep fading. To solve this problem, a hybrid relay-aided D2D communication scheme with a two-antenna infrastructure and u...

Duplex kidney (DK) is the most common congenital abnormality of the urinary tract, with an incidence of around 0.82%1,2. Basis of duplex kidney formation by embryology is explained as development of two ureteral buds separately from a single mesonephric duct gives rise to a duplex kidney with complete ureteral duplication. On the other hand, bifurcation of a single ureteral bud proximal to the ...

G-quadruplexes and i-motifs are complementary examples of non-canonical nucleic acid substructure conformations. G-quadruplex thermodynamic stability has been extensively studied for a variety of base sequences, but the degree of duplex destabilization that adjacent quadruplex structure formation can cause has yet to be fully addressed. Stable in vivo formation of these alternative nucleic acid...

Hypokalemia FIGURE 3-16 Comparison of duplex ultrasound with arteriography. A total of 102 consecutive patients with both duplex ultrasound scanning of the renal arteries and renal arteriography were prospectively studied. All patients in this study had difficult-to-control hypertension, unexplained azotemia, or associated peripheral vascular disease, giving them a high pretest likelihood of re...

A demonstration of a real-time full-duplex wireless link is presented, in which a pair of full-duplex transceivers perform simultaneous transmission and reception on the same frequency channel. A full-duplex transceiver is composed of a custom-designed small-form-factor analog self-interference canceller, and a digital self-interference cancellation implementation is integrated with the Nationa...
