background: glaucoma is one of the most common causes of blindness and is usually associated with elevated intraocular pressure. in patients with primary open angle glau-coma the number of trabecular meshwork cells is decreased. death of the trabecular meshwork cells may be a result of apoptosis. objective: to investigate the aqueous humor levels of soluble fas (sfas) and fas-ligand (sfasl) in ...

compressible gas flow inside a convergent-divergent nozzle and its exhaust plume atdifferent nozzle pressure ratios (npr) have been numerically studied with severalturbulence models. the numerical results reveal that, the sst k–ω model give the bestresults compared with other models in time and accuracy. the effect of changes in value ofdivergence half-angle (ε ) on the nozzle performance, thru...

conclusions by using the normal angle kappa determined in this study, pseudodeviations can be identified more precisely in those who might undergo keratorefractive surgery. results a total of 977 healthy participants who aged 18 to 45 years were included consecutively. the study population consisted of 614 females and 363 males. the average angle kappa was 5.00º ± 1.36º at 240.21º ± 97.17º in m...

Introdouction: The purpose of the present study was to determine the possible relationship between gonial angle size and three mandibular morphometric parameters, namely, panoramic mandibular index (PMI), mandibular cortical width (MCW), and antegonial notch depth (AD), in digital panoramic radiographs. Materials and methods: PMI, MCW, and AD were calculated in digital panoramic radiographs of...

The blades of wind turbines are the most important parts in producing power output. In this study, a section of a 660 KW wind turbine blade will be installed in Iran in near future was tested in a wind tunnel. In addition to steady tests, various unsteady tests including the effects of reduced frequency, mean angle of attack, and amplitudes were carried out. The preliminary results show strong ...

objective: to compare the frequency of helicobacter pylori (h. pylori) infection in subjects with primary open angle glaucoma (poag) vs controls. methods: in a case-control study, 44 patients with primary open angle glaucoma and 79 patients with senile cataract (control group) were investigated for serum level of anti-h. pylori antibody using the enzyme-linked immunosorbant assay (elisa) method...

The purpose of this study was to investigate the minimum acceptable viewing angle (MIAVA) for different age groups while reading the Chinese e-book. Ninety subjects participated in this study. Their age ranged from 21 to 70 years, and they were divided into three age groups, i.e. young, middle, and old groups. Each subject was firstly asked to adjust personal preferred viewing distance. The min...

Direct visualization and assessment of the iridocorneal angle (ICA) region with high resolution is important for the clinical evaluation of glaucoma. However, the current clinical imaging systems for ICA do not provide sufficient structural details due to their poor resolution. The key challenges in achieving high quality ICA imaging are its location in the anterior region of the eye and the oc...
