BACKGROUND AND OBJECTIVES Phosphoribosylation of 5-fluorouracil (5-FU) is an essential step which leads to tumor growth inhibition and orotate phosphoribosyl transferase (OPRT) is the main enzyme that involves in this conversion of 5-FU to 5-fluorouridine monophosphate. This retrospective study was aimed to evaluate the correlation between tumor OPRT(More)
PURPOSE Peripheral cone dystrophy is a subgroup of cone dystrophy, and only 4 cases have been reported. We present a patient with unilateral peripheral cone dysfunction and report the functional changes determined by electrophysiological tests and ultrastructural changes determined by spectral domain optical coherence tomography (SD-OCT). CASE A(More)
Orotate phosphoribosyl transferase (OPRT) is the main enzyme that involves in phosphoribosylation of 5-fluorouracil (5-FU), an essential step that leads to tumor growth inhibition. In our study, the prognostic relevance of OPRT, thymidylate synthase (TS) and dihydropyrimidine dehydrogenase (DPD) in resectable colorectal cancer (CRC) patients treated by oral(More)
AIMS To evaluate the recovery of retinal function and the thicknesses of the photoreceptor inner (IS) and outer segment (OS) layers after a reattachment of a rhegmatogenous retinal detachment (RRD). METHODS 49 eyes of 49 patients (mean age, 57.4±10.3 years) with successfully reattached RRD were retrospectively studied. Spectral-domain optical coherence(More)
PURPOSE Retinal vascular abnormalities are rare in patients with Churg-Strauss syndrome. We present the findings in a patient with Churg-Strauss syndrome who developed bilateral central retinal artery occlusion simultaneously. METHODS Case report. RESULTS A 68-year-old Japanese man developed acute bilateral vision decrease to counting finger in the(More)
Background. To report the outcome of pars plana vitrectomy (PPV) combined with intraoperative endolaser focal photocoagulation (PC) on eyes with idiopathic macular telangiectasis (MacTel) type 1. Methods. This was a retrospective study of two female patients with MacTel type 1 who were resistant to focal photocoagulation, sub-Tenon triamcinolone injection,(More)
PURPOSE To compare the effects of carbon beam irradiation with those of proton beam irradiation on the physiology of the retina of rats. METHODS AND MATERIALS Eight-week-old Wister rats were used. The right eyes were irradiated with carbon beam (1, 2, 4, 8, and 16 Gy) or proton beam (4, 8, 16, and 24 Gy) with the rats under general anesthesia.(More)
The purpose of this study is to identify factors contributing to tooth retention. A questionnaire was prepared which includes 22 main items concerning oral health care. The questionnaire was answered by 144 females in their 80's at 4 Health and Welfare Centers for the Aged in the City of Naha in July 1995 through interview format. Data were analyzed using(More)
Intravitreal injections (IVI) have become a part of daily practice for a growing number of procedures. We evaluated the retinal function by recording intraoperative photopic electroretinograms (ERGs) before an injection (T1), just after the injection (T2), and after the aspiration of the anterior chamber fluid (T3) of 19 eyes of 19 patients (mean age 70.6(More)
