antibiotic resistance of intensive care unit (icu) born aerobic gram-negative bacteria was evaluated during a six months period at a teaching hospital in tehran, and determination of the validity of the results obtained from disc diffusion tests, using discs manufactured in iran. disc susceptibility tests using iranian and standard discs (diffusion discs available in international markets) were...

purpose : to report a rare case of large vascularized astrocytoma on optic disc. case report : a 12-year-old boy with history of decreased vision in the left eye since 5-6 months ago was referred to the ocular oncology service at rassoul akram hospital with provisional diagnosis of retinoblastoma. on examination, visual acuity was counting fingers at 50 cm, and a 3+ relative afferent pupillary ...

conclusions the present data do not suggest that pregabalin is more efficacious than placebo in the treatment of lumbar and cervical radicular pain. however, the small sample size of this study may have affected the ability to detect such a difference. results data on 19 of the 39 patients recruited were available for analysis. no statistically significant differences in the pain, disability, a...

STUDY DESIGN A cross-sectional study design was used. OBJECTIVE The objective was to examine the influences of body anthropometrics, axial disc area, and lifting strength on disc degeneration and to compare these with the effects of lifetime physical demands and age. SUMMARY OF BACKGROUND DATA Although recent studies have shown that heredity is a dominant factor in disc degeneration, the co...

Farm machinery selection, operation and management directly impact crop cultivation processes outputs. A priori quantification of technical financial needs allows definition proportionate distribution available resources simplification selection process. Appropriate planning, association adjustment the power unit implement are required for soil cultivation. Consideration functional parameters i...

Accurately detection of retinal landmarks, like optic disc, is an important step in the computer aided diagnosis frameworks. This paper presents an efficient method for automatic detection of the optic disc’s center and estimating its boundary. The center and initial diameter of optic disc are estimated by employing an ANN classifier. The ANN classifier employs visual features of vessels and th...

Three-dimensional L4-L5 finite element (FE) models of three disc heights (9.5mm, 11.5mm, and 13.5mm) and three disc wedge angles (5o, 8 o, and 10 o) were developed to investigate their effect on L4-L5 lumbar motion segment under pure axial compressive loading. The FE predictions indicated that the axial disc displacement and the posterior disc bulge increased greatly with an increase in the ave...

We investigate the accretion disc structure in the strongly Comptonised spectra seen at high luminosities from galactic black holes (variously termed the very high or steep power law dominant state). We use simultaneous ASCA-RXTE data on two such spectra from the black hole transient XTE J1550-564 to constrain the disc and Comptonized luminosity. The broad bandpass of the data gives robust esti...
