We measured contrast thresholds for Gabor targets in the presence of maskers which had higher or lower spatial frequencies than the targets. A high-pass fractal masker elevated target contrast thresholds at low and intermediate pedestal contrasts in both monocular and dichoptic modes of presentation, suggesting that the masking occurs after a monocular processing stage. Moreover we found that a...

AIM To substantiate the high incidence of monocyte esterase deficiency (MED) in gastrointestinal carcinoma already reported in a small group of patients; to compare the clinical findings in esterase deficient and esterase positive patients. METHODS Peripheral blood smears (n = 22) or cytocentrifuge preparations (n = 52) of mononuclear cells from the peripheral blood of patients with gastroint...

Binocular rivalry occurs when different images are presented one to each eye: the images are visible only alternately. Monocular rivalry occurs when different images are presented both to the same eye: the clarity of the images fluctuates alternately. Could both sorts of rivalry reflect the operation of a general visual mechanism for dealing with perceptual ambiguity? We report four experiments...

According to studies, a significant association exists between the low levels of vitamin D and cardiovascular diseases such as myocardial infarction (MI). In a prospective, case control study, 88 patients with acute coronary syndrome (ACS) including ST elevation myocardial infarction (STEMI) and Non-STEMI were enrolled. The plasma level of 25-hydroxy vitamin D[25(OH)D] was obtained at the time ...

Phacoemulsification with mechanical pupil dilation was performed on a functionally monocular glaucoma patient with pseudoexfoliation syndrome. The postoperative course was complicated by persistent intraocular hemorrhaging from the pupil margin in multiple locations that ceased temporarily with a marked elevation in intraocular pressure (IOP). Normalization of IOP with medication or paracentesi...
