PURPOSE To characterize retinal functional consequences of elevated intraocular pressure (IOP) in a rat model of experimental glaucoma. METHODS Unilateral elevation of IOP was produced by hypertonic saline injection into an episcleral vein in 20 adult male Brown-Norway rats. IOP was measured in both eyes of awake animals four to five times per week. After(More)
PURPOSE To describe varicosities of intraretinal ganglion cell axons in the nerve fiber layer of human and nonhuman primate retinas. METHODS Intraretinal ganglion cell axons of seven human donors (1-85 years old) and two nonhuman primates (Macaca mulatta, 15 and 17 years old) were immunohistochemically stained with an antibody of neurofilament on(More)
Contamination of lettuce by Salmonella has caused serious public health problems. Polymerase chain reaction (PCR) allows rapid detection of pathogenic bacteria in food, but it is inaccurate as it might amplify DNA from dead target cells as well. This study aimed to investigate the stability of DNA of dead Salmonella cells in lettuce and to develop an(More)
Non-alcoholic fatty liver disease (NAFLD) is a condition associated with metabolic disturbances. The aim of the present study was to investigate the biochemical characteristics and risk factors for NAFLD. The study was carried out in a total of 881 subjects diagnosed by ultrasonography. NAFLD occurred mainly in middle-aged individuals, with a prevalence of(More)
PURPOSE Glial cells are structurally and functionally linked to neuronal tissues. Pathologically, the cells may be activated and characterized by increased size and number and altered cellular properties. In glaucoma, pathologic mechanisms within the anterior optic nerve may include glial activation. This study examines morphologic changes of glial cells in(More)
The efficiency of tranilast for the treatment of proliferative vitreoretinopathy (PVR) was investigated in vitro. A tetrazolium-based colorimetric assay showed that the 300-microM concentration of tranilast inhibited proliferation of bovine retinal pigment epithelial (RPE) cells and rabbit dermal fibroblasts with no toxicity. The contraction of collagen(More)
OBJECTIVE To assess endothelin B receptor (ETbR) expression in human glaucomatous optic nerves and the spatial relationship between ETbR and astrocytes. METHODS Twenty-six eyes from 16 glaucoma patients and 10 normal control subjects were immunohistochemically labeled with antibodies to ETbR. The immunoreactivity was quantified and compared between normal(More)
PURPOSE To assess the structural and functional consequences of local ganglion cell (GC) loss in an experimental model of a retinal nerve fiber layer (NFL) bundle defect. To evaluate and compare three commonly used multifocal electroretinogram (mfERG) stimuli, as well as the standard transient pattern-reversal ERG (pERG) and the photopic full-field ERG, for(More)
The mechanism of apical Na(+)-dependent H(+) extrusion in colonic crypts is controversial. With the use of confocal microscopy of the living mouse distal colon loaded with BCECF or SNARF-5F (fluorescent pH sensors), measurements of intracellular pH (pH(i)) in epithelial cells at either the crypt base or colonic surface were reported. After cellular(More)
The tremendous therapeutic potential of peptides has not yet been realized, mainly owing to their short in vivo half-life. Although conjugation to macromolecules has been a mainstay approach for enhancing protein half-life, the steric hindrance of macromolecules often harms the binding of peptides to target receptors, compromising the in vivo efficacy.
