In this study, the effects and interactions of reaction time and capping agent assistance during sol-gel synthesis of magnesium substituted hydroxyapatite nanopowder (MgHA) on hydroxyapatite (HA) to β-tricalcium phosphate (β-TCP) ratio, Ca/P ratio and mean crystallite size was examined experimentally as well as through statistical analysis. MgHA nanopowders were synthesized by sol-gel technique...
هدف از این پژوهش بررسی اثر هشت هفته تمرین پر شدت تناوبی بر میزان روی آلفا2 گلیکوپروتئین پلاسمایی و بافت چربی رت های نر چاق شده با رژیم غذایی پرچرب بود. بدین منظور 3 گروه تمرین تناوبی، کنترل (رژیم غذای پرچرب) و شاهد (رژیم غذایی طبیعی) در نظر گرفته شد. مداخله ی ورزشی به مدت 8 هفته به صورت برنامه ی تناوبی با شدت زیاد، با تناوب های کوتاه 15 تا 30 ثانیه و تعداد 5 تا 12 تکرار (1 دقیقه استراحت فعال بی...
PURPOSE To evaluate the utility of carotid ultrasound in patients with asymptomatic Hollenhorst plaques. METHODS Retrospective chart review of 237 patients diagnosed with Hollenhorst plaques between 1996 and 2004. The baseline cardiovascular risk profile, medications, and carotid ultrasound findings were documented. Retinal ischemia, myocardial ischemia, and cerebrovascular events during foll...
The purpose of this study was to evaluate color stability of two dental ceramics cemented with two resin cements, assessing the color difference (ΔE00) by the measurement of L*, a*, b*, c* and h* of transmittance. The combination of two ceramic system (feldspathic and lithium disilicate) and two resin cements - color A3 (RelyX ARC and Variolink II) resulted in 4 groups (n=5). Ten disks-shaped s...
OBJECTIVES This study investigated the effect of extreme cooling methods on the flexural strength, reliability and shear bond strength of veneer porcelain for zirconia. METHODS Vita VM9 porcelain was sintered on zirconia bar specimens and cooled by one of the following methods: inside a switched-off furnace (slow), at room temperature (normal) or immediately by compressed air (fast). Three-po...
