PURPOSE: Trypan blue (TB) is used for visualization of the endothelium-Descemet membrane graft during Descemet membrane endothelial keratoplasty (DMEK). However, TB is assumed to have a dose-dependent toxic effect on the corneal endothelium. We retrospectively compared a lutein/zeaxanthin and Brilliant Blue (LZ/BB)-based dye for preparation and transplantation of the graft in DMEK to TB. METHODS: In 20 patients, a dye composed of 1% LZ /0.025% BB was used, and in 22 patients, 0...

BACKGROUND: In Vietnam, like many countries in Southeast Asia, the commonly used approach of center-based compulsory drug treatment (CCT) has been criticized on human rights ground. Meanwhile, community-based voluntary methadone maintenance treatment (MMT) has been implemented for nearly a decade with promising results. Reform-minded leaders have been seeking empirical evidence of the costs and effectiveness associated with these two main treatment modalities. Conducting evaluations of these treatments, especially where randomization is not ethical, presents challenges...

BACKGROUND: Major depressive disorder (MDD) is associated with hypoactivation of the dorsolateral prefrontal cortex, a brain region involved in emotion regulation and basic cognitive control processes. Recent studies have indicated that computerized interventions designed to activate this region may reduce depressive and ruminative symptoms. In this double-blind randomized controlled trial, we tested whether one such program, called Cognitive Control Training (CCT), enhanced treatment outcomes when used in adjunct to brief behavior therapy for MDD...

Rice flowering is controlled by changes in the photoperiod that promote the transition to the reproductive phase as days become shorter. Natural genetic variation for flowering time has been largely documented and has been instrumental to define the genetics of the photoperiodic pathway, as well as providing valuable material for artificial selection of varieties better adapted to local environments. We mined genetic variation in a collection of rice varieties highly adapted to European regions and isolated distinct variants of the long day repressor HEADING DATE 1 (Hd1) that perturb its expression or protein function...

OBJECTIVES: Hormonal changes during oral contraceptive pill (OCP) use may affect central corneal thickness (CCT) values. We aimed to evaluate the impact of OCP use on CCT values in healthy young women. MATERIALS AND METHODS: Fifty women subjects who use OCP for contraception (Group 1) and forty control subjects (Group 2) who do not use OCP were included in this prospective study. None of the patients had any history of systemic or ocular diseases. The CCT values measured by ultrasonic pachymeter (Nidek US-4000 Echoscan, Japan) and the intraocular pressure (IOP) values were measured by noncontact tonometer (Reichert 7 CR Corneal Response Technology, USA) at the time of admission to our clinic...

PURPOSE: To evaluate the influence of increases in light scattering on intraocular lens (IOL) surfaces on paraxial forward scattering using goniophotometry and Hartmann-Shack wavefront aberrometry. METHODS: Surface light scattering was reproduced experimentally by acceleratedly aging 4 intraocular lenses by 0, 3, 5, and 10 years each. Light scattering from both IOL surfaces was measured using Scheimpflug photography. The paraxial forward scattering from the aged IOLs was measured using a goniophotometer with a halogen light source (wavelength: 350-850 nm) and telecentric optics, and changes in the maximum intensity and full width at 10% of maximum intensity (FW10%) were evaluated...

BACKGROUND: Recurrent aphthous stomatitis (RAS) is the most common chronic oral mucosal condition of the oral cavity. Investigators in clinical trials have evaluated the effectiveness of Chinese patent medicines in the treatment of RAS. However, the results are conflicting rather than conclusive. To evaluate the efficacy and safety of Chinese patent medicines for the treatment of RAS, the authors conducted a systematic review. TYPES OF STUDIES REVIEWED: The authors searched 9 electronic databases to identify randomized controlled trials (RCTs) or potential clinical controlled trials (CCTs), published in any language, in which the investigators compared Chinese patent medicines with vitamin tablets or placebos for the treatment of RAS...

A novel apatite mineral of Ba5(PO4)2SiO4 was synthesized successfully using a traditional high temperature solid-state reaction. Its structure was determined by high-resolution transmission electron microscopy, fast Fourier transform, energy dispersive X-ray spectroscopy, and X-ray powder diffraction Rietveld refinement, and this was found to be a hexagonal crystal system with the space group attributed to P63/m (176). Moreover, a series of Eu(2+) doped Ba5(PO4)2SiO4 phosphors were investigated. The photoluminescence (PL) properties of Ba5(PO4)2SiO4:Eu(2+) were investigated in detail by density functional theory calculations, diffuse reflection spectra, emission-excitation spectra, decay curves, and temperature dependence spectra...

PURPOSE: To demonstrate the feasibility of a rapid computational algorithm for generating esophageal margin expansions. METHODS: Inter-fraction MRI allows visualization of relative variations of the esophagus and other critical structures when compared to planning CT. We have developed a rapid computational method for quantifying this motion. CT simulation and on-treatment MR data sets of seven patients were obtained using a 0.3 T MR-guided RT system. Rigid registration guided by bony anatomy from the cricoid to the gastro-esophageal junction was used for transferring CT contours to MR volumes...

INTRODUCTION: Class III malocclusion affects between 5% and 15% of our population. The 2 most common dilemmas surrounding Class III treatment are the timing of treatment and the type of appliance. A number of appliances have been used to correct a Class III skeletal discrepancy, but there is little evidence available on their effectiveness in the long term. Similarly, early treatment of Class III malocclusion has been practiced with increasing interest. However, there has been no solid evidence on the benefits in the long term...

Do day-to-day emotions, social interactions, and sleep play a role in determining which anxious youth respond to supportive child-centered therapy (CCT) versus cognitive behavioral therapy (CBT)? We explored whether measures of day-to-day functioning (captured through ecological momentary assessment, sleep diary, and actigraphy), along with clinical and demographic measures, were predictors or moderators of treatment outcome in 114 anxious youth randomized to CCT or CBT. We statistically combined individual moderators into a single, optimal composite moderator to characterize subgroups for which CCT or CBT may be preferable...

A promising energy transfer (Tm(3+)→Tb(3+)→Eu(3+)) approach is brought forward to generate white light emission under ultraviolet (UV) light excitation for solid state lightening. Tm(3+)/Tb(3+)/Eu(3+) ions are combinedly doped in zinc borate glass system in view of understanding energy transfer process resulting in white light emission. Zinc borate (host) glass displayed optical and luminescence properties due to formation of Zn(II)x-[O(-II)]y centres in the ZnB glass matrix. At 360nm (UV) excitation, triply doped Tm(3+)/Tb(3+)/Eu(3+): ZnB glasses simultaneously shown their characteristic emission bands in blue (454nm: (1)D2→(3)F4), green (547nm: (5)D4→(7)F5) and red (616nm: (5)D0→(7)F2) regions...
