PURPOSE To evaluate a spectral imaging technique to detect the area of internal limiting membrane (ILM) peeling after vitrectomy for idiopathic macular hole. MATERIALS AND METHODS In a prospective study, 15 eyes of 15 patients with idiopathic macular holes were tested. After vitrectomy with ILM peeling, retinal images were taken with color fundus photography, red-free fundus photography, and ...

We demonstrate efficient generation of singlet oxygen upon two-photon excitation with 150-fs 780-nm laser pulses of a new porphyrin photosensitizer molecule whose two-photon absorption cross section has been considerably enhanced by chemical design.

BACKGROUND Mean systolic blood pressure in apparently healthy cats has been reported as approximately 125 mmHg using direct assessment, but there is greater variability in reported values using indirect assessment. Increasing age and the white-coat effect are associated with increased systolic blood pressure. HYPOTHESIS/OBJECTIVES To report Doppler-derived blood pressure measurements from a l...

ism against pathogens. Central to maintaining immunity is cell-surface presentation of antigenic peptides to specific receptors on CD8 cytotoxic T lymphocytes by class I major histocompatibility complex (MHC) molecules on infected cells. This cell-mediated recognition process results in the elimination of infected cells and is critically important to maintain immunity against virus and tumors. ...

As part of a structural investigation of strontium tellurate(IV) (STO), SrTeO(3), with particular emphasis on the crystal chemistry and phase transitions, the structure of the δ-phase has been determined at 780 K using a single-crystal analysis. Both structural and non-linear optical measurements indicate that STO undergoes a γ→δ second-order ferroelectric phase transition at 633 K from the C2 ...
