To evaluate the ability of spectral-domain optical coherence tomography (SD-OCT) images of the inner/outer segment (IS/OS) junction to predict macular hole surgery outcomes. Fifty-four eyes in 53 patients with idiopathic macular holes were studied. Postoperative visual acuity and SD-OCT images of the fovea were examined before and 12 months after surgery.(More)
Plants precisely control lignin deposition in spiral or annular secondary cell wall domains during protoxylem tracheary element (TE) development. Because protoxylem TEs function to transport water within rapidly elongating tissues, it is important that lignin deposition is restricted to the secondary cell walls in order to preserve the plasticity of(More)
PURPOSE To report a case of bilateral regression of choroidal metastasis with adenocarcinoma of the lung treated with gefitinib. METHODS Retrospective case review of a 68-year-old woman with pulmonary adenocarcinoma with choroidal metastasis who presented with visual loss in the left eye as the initial manifestation. Her visual acuity was 6/6 in the right(More)
The necessary and sufficient condition of the channel capacity is rigorously formulated for the N -user discrete memoryless multiple-access channel (MAC). The essence is to invoke an elementary MAC where sizes of input alphabets are not greater than the size of output alphabet. The main objective is to demonstrate that the channel capacity of an MAC is(More)
The secretion of cell wall polysaccharides through the trans-Golgi network (TGN) is required for plant cell elongation. However, the components mediating the post-Golgi secretion of pectin and hemicellulose, the two major cell wall polysaccharides, are largely unknown. We identified evolutionarily conserved YPT/RAB GTPase Interacting Protein 4a (YIP4a) and(More)
Lipid secretion from epidermal cells to the plant surface is essential to create the protective plant cuticle. Cuticular waxes are unusual secretory products, consisting of a variety of highly hydrophobic compounds including saturated very-long-chain alkanes, ketones, and alcohols. These compounds are synthesized in the endoplasmic reticulum (ER) but must(More)
PURPOSE To evaluate the anatomic features of the photoreceptor inner/outer segment (IS/OS) junction before and after surgery by spectral-domain optical coherence tomography in patients undergoing idiopathic epiretinal membrane (ERM) surgery and to correlate these features with the functional outcomes. DESIGN Prospective, cohort study. METHODS We(More)
PURPOSE To evaluate the macular structure on spectral-domain optical coherence tomographic (SD-OCT) images to predict the outcome of surgery for idiopathic epiretinal membrane. METHODS Forty-five eyes of 45 consecutive patients with idiopathic epiretinal membrane who had a preoperative visual acuity of ≤ 20/32 and were scheduled to undergo a(More)
BACKGROUND our purpose was to report the results of 1-year follow-up examinations after intravitreal bevacizumab injection for the treatment of chronic central serous chorioretinopathy (CSC). METHODS five eyes in 5 patients with chronic CSC were intravitreally injected with 1.25 mg/0.05 ml of bevacizumab. The need for retreatment was evaluated if(More)
