SUMMARY OBJECTIVE To assess weight loss strategies and behaviors in obese patients prior to seeking professional obesity treatment in Taiwan. DESIGN A cross-sectional study was conducted between 1 July 2004 and 30 June 2005. SETTING AND SUBJECTS Obese subjects (1060; 791 females; age, ≥18 years; median BMI, 29.5 kg/m(2)) seeking treatment in 18 Taiwan clinics specializing in obesity trea...

PURPOSE To investigate the retinal and choroidal vascular pattern, structure, and thickness using high-speed, high axial resolution, swept-source optical coherence tomography (SS-OCT) at 1060 nm, demonstrating enhanced penetration through all choroidal layers. METHODS An ophthalmic SS-OCT system was developed operating at 57,000 A-lines/s with 5.9 μm axial resolution and was used to collect 3...

Polymer waveguides have emerged as a viable technology for integrated optical devices due to their high packaging density, low cost, capability of integration with other material systems, and ease of fabrication and modification of their chemical structure. This latter property offers enormous flexibility in the design of waveguide laser media. Although laser action has been achieved in many op...

This essay looks at six APS classic papers published by D. H. Hubel and T. N. Wiesel that first identified a developmental critical period for environment influenced receptive field plasticity in the visual pathway. These classic papers are freely available online. These are listed here, in chronological order. Wiesel TN, Hubel DH. Effects of visual deprivation on morphology and physiology of c...

PURPOSE To demonstrate ultrahigh-speed optical coherence tomography (OCT) imaging of the retina and optic nerve head at 249,000 axial scans per second and a wavelength of 1060 nm. To investigate methods for visualization of the retina, choroid, and optic nerve using high-density sampling enabled by improved imaging speed. METHODS A swept-source OCT retinal imaging system operating at a speed ...

Cytotoxic T lymphocytes (CTL) specific for human minor histocompatibility (H) antigens can be isolated from the blood of major histocompatibility complex (MHC)-matched allogeneic bone marrow transplant (BMT) recipients and may play a prominent role in the graft-versus-host (GVH) and graft-versus-leukemia (GVL) reactions (Tsoi et al, J Immunol 125:2258, 1980; Tsoi et al, Transplant Proc 15:1484,...
