We report a new line-narrowing effect associated with triple-quantum resonance in a two-level NMR system. The experiment was carried out in the rotating frame on (19)F nuclei in Teflon; namely, the magnetization is spin-locked along the RF field and the triple-quantum resonance is induced by the oscillating field perpendicular to the RF field. We observed that the decay time of the triple-quant...

Approximately half of the world’s population is infected by Helicobacter pylori [1], which causes various gastrointestinal diseases including gastritis, peptic ulcer, gastric mucosaassociated lymphoid tissue lymphoma, and gastric cancer [2,3]. Korean guidelines, which were revised in 2013, by the Korean College of Helicobacter and Upper Gastrointestinal Research strongly recommend that H. pylor...

An internal triple-band antenna fed by a microstrip line is proposed for operating PCS, IMT-2000, and Bluetooth bands. By using the two branchs of meander line, the desired resonant frequencies can be achieved. A broadband characteristic for each band is optimized by tunning the parts of radiating patch and size of each strip line segments. The proposed antenna and substrate are small enough to...

Steiner triple systems are known to exist for orders n ≡ 1, 3 mod 6, the admissible orders. There are many known constructions for infinite classes of Steiner triple systems. However, Steiner triple systems that lack prescribed configurations are harder to find. This paper gives a proof that the spectrum of orders of 5-sparse Steiner triple systems has arithmetic density 1 as compared to the ad...

The transmission spectra of a Fabry-Perot etalon coupled to a microtoroid resonator are studied theoretically and experimentally. The resonance line shapes depend strongly on the resonance wavelength detuning and coupling strength between the two resonators. A wide variety of line shapes, ranging from a single to triple peaks, symmetric to asymmetric Fano-like peaks, and notches were predicted ...

A large variety of cells adhere to and spread on specific regions within the triple helix of collagens, mainly via α1β1 and α2β1 integrins. Disruption of collagen triple helical integrity generally affects the efficiency of cell adhesion on different collagens including collagen V. This report addresses the question of the importance of the linear sequence of the constitutive α-chains versus th...

Oral metronomic chemotherapy may target tumor cells indirectly via antiangiogenic activity, restoration of anticancer immune response, or induction of tumor dormancy. We initiated the single-center, randomized, open-label, phase II study to determine whether the addition of metronomic cyclophosphamide to docetaxel (T) (w/o trastuzumab) improves overall response rate (ORR) as first-line treatmen...

Triple helix forming oligonucleotides can direct DNA damaging agents at specific sites in an intact double helix. In our study, triple helix formation was demonstrated in a SV40 based shuttle vector treated with psoralen linked to a 22-mer purine rich oligonucleotide. UVA irradiation caused a covalent linkage of the oligonucleotide through the psoralen to the mutational supF marker gene of the ...
