BACKGROUND: Utility of diagnostic adjuncts (DAs) in an adult population with a low oral and pharyngeal cancer (OPC) prevalence is unclear. In this study, we compare the effectiveness of DAs and clinicians' conventional oral examination (COE) in detecting oral and pharyngeal cancers (OPC), in high-risk (HR) users, low-risk (LR) and ...

Linezolid is an important agent for the treatment of infections because of vancomycin-resistant Enterococcus (VRE). This study identified independent predictors for isolation of linezolid-resistant VRE (LZD-R-VRE) and analyzed outcomes associated with linezolid resistance. Immunosuppression, prior surgery, and previous exposure to β-lactam antibiotics were independent predictors for isolation of LZD-R-VRE but ...

Nonlinear dynamics of wave packets in parity-time-symmetric optical lattices near the phase-transition point is analytically studied. A nonlinear Klein-Gordon equation is derived for the envelope of these wave packets. A variety of phenomena known to exist in this envelope equation are shown to also exist in the full equation, including ...

It is shown that timing jitter in optical parametric chirped-pulse amplification induces spectral drifts that transfer to carrier-envelope phase (CEP) instabilities via dispersion. Reduction of this effect requires temporal synchronization, which is realized with feedback obtained from the angularly dispersed idler. Furthermore, a novel method to measure the CEP drifts ...

Study objectives were to compare mental health outcomes of a peer-led recovery group, a clinician-led recovery group, and usual treatment and to examine the effect of group attendance on outcomes. The study used a randomized design with three groups: a recovery-oriented peer-led group (Vet-to-Vet), a clinician-led recovery group, and usual ...

The present study was designed to investigate whether cyclooxygenase (COX) inhibitors (coxibs) could prolong survival time by attenuating the tumor growth of ovarian cancer xenograft-bearing mice. Tumor growth and survival time were observed and compared in mice which were treated with a COX-1 inhibitor (SC-560) and a COX-2 inhibitor (celecoxib) ...

The goal was to investigate the correlation between molecular mobility and physical stability and identify the specific mobility mode responsible for instability. The molecular mobility of amorphous itraconazole, in the glassy as well as the supercooled liquid state, was comprehensively characterized using dynamic dielectric spectroscopy. Isothermal frequency sweeps in the ...

Ice-binding proteins (IBPs) can bind to the ice crystal and inhibit its growth. Because this property of IBPs can increase the freeze-thaw survival of cells, IBPs have attracted the attention from industries for their potential use in biotechnological applications. However, their use was largely hampered by the lack of the ...

Dual-comb spectroscopy is extended to the visible spectral range with two short-pulse frequency-doubled free-running ytterbium-doped fiber lasers. When the spectrum is shifted to other domains by nonlinear frequency conversion, tracking the relative fluctuations of the femtosecond oscillators at their fundamental wavelength automatically produces the correction signal needed for the recording ...

Optical microsystems have become important tools for imaging, optofluidics, and sensor applications. Here we show a versatile method to create microlens arrays (MAs) exploiting spatial-light-modulator-assisted polarization holography, which enables an efficiency of diffraction up to 100%. We demonstrate the large flexibility of the proposed approach by codifying mixed MAs, i.e., ...

Laguerre-Gaussian (LG) beams are used in many research fields, including microscopy, laser cavity modes, and optical tweezing. We developed a holographic method to generate pure LG modes (amplitude and phase) with a binary amplitude-only digital micromirror device (DMD) as an alternative to the commonly used phase-only spatial light modulator. The ...

A reduction of more than 20 dB of the intensity noise at the antiphase relaxation oscillation frequency is experimentally demonstrated in a two-polarization dual-frequency solid-state laser without any optical or electronic feedback loop. Such behavior is inherently obtained by aligning the two orthogonally polarized oscillating modes with the crystallographic axes of ...

Habitat selection fundamentally drives the distribution of organisms across landscapes; density-dependent habitat selection (DDHS) is considered a central component of ecological theories explaining habitat use and population regulation. A preponderance of DDHS theories is based on ideal distributions, such that organisms select habitat according to either the ideal free, despotic, ...

Benzo[a]pyrene-7,8-dihydrodiol-9,10-epoxide (BPDE), a metabolite of Benzo[a]pyrene (B[a]P), is a high-risk factor for development of a number of cancers. DNA damage caused by BPDE is normally repaired by Nucleotide Excision Repair system of which ERCC1 exerts an important role. We investigated whether two single nucleotide polymorphisms in ERCC1 (C19007T; rs11615 and ...

Brachymetatarsia is a rare clinical entity that presents a challenging problem for surgeons. One-stage lengthening with an autologous bone graft has been preferred for metatarsals that require a limited lengthening. With a gradual lengthening of metatarsals, callus distraction (callotasis) can achieve a greater length gain and a concomitant lengthening of ...

We theoretically investigate mode-locked regimes of optical-frequency combs generated in a nonlinear ring microresonator pumped with continuous-wave light. We find that breather solitons can be formed in the resonator for certain values of frequency and power of the pump. We argue that relatively slow modulation of the comb-frequency harmonics observed ...

This research carries out coherence measurements of a 42.7 GHz quantum dash (QDash) semiconductor laser when passively, electrically, and optically mode-locked. Coherence of the spectral lines from the mode-locked laser is determined by examining the radio frequency beat-tone linewidth as the mode spacing is increased up to 1.1 THz. Electric-field measurements of ...
