An efficient polarization beam splitter (PBS) based on an optofluidic ring resonator (OFRR) is proposed and experimentally demonstrated. The PBS relies on the large effective refractive index difference between transverse-electric (TE) and transverse-magnetic (TM) polarization states, since the silica-microcapillary-based OFRR possesses a slab-like geometry configuration in the cross section th...

PURPOSE Aluminum hydroxide (Al) is an adjuvant to induce Th2 immune responses. The aim of this study is to investigate the effects of pretreatment with Al on experimental autoimmune uveoretinitis (EAU), a Th1 disease model. METHODS Lewis rats were pretreated with an uveitogenic peptide (#29)/Al, phosphate-buffered saline (PBS)/Al or PBS. EAU was then induced by immunization of #29 in complete...

Organic pollutant is an environmentally harmful and ubiquitous aquatic with extensive production application. In this study, a unique novel TiO2-based dual-sensitized heterojunction photocatalyst (PbS/CdS/TiO2) was successfully obtained by one step hydrothermal method, chemical bath deposition (CBD) method ionic layer adsorption reaction (SILAR) method. Scanning electron microscopy, X-ray photo...

BACKGROUND Some reports have suggested that, in vitro, human heart chymase in homogenates contributes little to angiotensin (Ang) II formation in the presence of natural protease inhibitors such as alpha-antitrypsin. We studied whether chymase bound to heparin, resembling an in vivo form, could contribute to Ang II formation in the presence of natural protease inhibitors. METHODS AND RESULTS ...

HIV type 1 (HIV-1) specifically uses host cell tRNALys-3 as a primer for reverse transcription. The 3' 18 nucleotides of this tRNA are complementary to a region on the HIV RNA genome known as the primer binding site (PBS). HIV-1 has a strong preference for maintaining a lysine-specific PBS in vivo, and viral genomes with mutated PBS sequences quickly revert to be complementary to tRNALys-3. To ...

METHODS. Corneas of BALB/c mice were injured with NaOH, irrigated copiously with PBS, and treated topically with either T 4 or PBS twice daily. At various time points after injury (PI), corneas from the T 4versus the PBS-treated group were examined for polymorphonuclear leukocyte (PMN) infiltration, chemokine, and matrix metalloproteinase (MMP)/tissue inhibitor of metalloproteinase (TIMP) expre...

In the recent years, the heterojunction solar cells based on quantum dots (QDs) have attracted attention due to strong light absorbing characteristics and the size effect on the bandgap tuning. This paper reports on the kinetics of interfacial charge separation of PbS QDs/(001) TiO 2 nanosheets heterojunction solar cells. PbS QDs are deposited using a bifunctional linker molecule on two differe...

Sub-10 nm monodisperse PbS cubes are synthesized by reacting quasi-spherical PbS nanocrystals with (NH4)2S. This reaction shapes the quasi-spheres into cubes via preferential growth of the (111) facets. A four-band envelope function calculation of the energy levels accounts well for the measured absorption spectra. Initial studies show that PbS cubes can organize into simple square superlattice...

The purpose of this study is to determine whether organ sparing and target coverage can be simultaneously maintained for pencil beam scanning (PBS) proton therapy treatment of thoracic tumors in the presence of motion, stopping power uncertainties, and patient setup variations. Ten consecutive patients that were previously treated with proton therapy to 66.6/1.8 Gy (RBE) using double scattering...
