purpose: to measure corneal power using different methods to assess agreement between these methods among patients who underwent photorefractive keratotomy. methods: in this prospective comparative study, keratometry was measured in 66 eyes of 33 refractive surgery candidates using manual keratometry (kr), conventional topography average central corneal power (accp), galilei total corneal power...

PURPOSE To assess the precision (repeatability and reproducibility) of ocular parameters measured by the Tomey OA-2000 biometer, and to compare them with those measured by the IOLMaster. METHODS In this prospective study, the right eyes of 108 healthy subjects were included. Three consecutive scans were obtained by 2 observers using the Tomey OA-2000, and in the same session one observer used...

Background: Anti-CCP is a test commonly used for the diagnosis of rheumatoid arthritis. The aim of this study was to determine the diagnostic values of ACCP compared to anti-MCV in rheumatoid arthritis patients in north of Iran. Methods: The serum samples of 150 RA patients and 75 controls, with the mean age of 49.6+11.8 and 48.8+12 years respectively, were tested using the commercially availa...

An integral domain is called atomic if every nonzero nonunit element factors into irreducibles. On the other hand, an said to satisfy ascending chain condition on principal ideals (ACCP) of stabilizes. It was asserted by P. Cohn back in sixties that satisfies ACCP, but such assertion refuted A. Grams seventies with a neat counterexample. Still, domains without ACCP are notoriously elusive, and ...

Calcium phosphate cements (CPCs) are successfully used as bone substitutes in dentistry and orthopaedic applications. This study investigated the physico-chemical-mechanical properties of and in vitro biological properties (cell response) of CPCs prepared with amorphous calcium carbonate phosphate (ACCP) doped with magnesium (ACCP-Mg), zinc (ACCp-Zn) or fluoride (ACCP-F) ions. The experimental ...
