Polyetheretherketone (PEEK) is a material suitable for frameworks of fixed dental prostheses. The effect of different surface treatments on the bond strength of PEEK bonded to human dentin was evaluated. One hundred PEEK cylinders (3 mm×3 mm) were divided into five groups according to surface treatment: silica coating, sandblasting with 45 μm Al2O3 particles, etching with 98% sulfuric acid for ...

Tomato  (L.ycopersicon esculentum  Mill.) cv. Rio Grande  seedlings were nutritionally conditioned with solutions complete fertilizer N(60% NO3+40% NH4)-P-K (20-20-20) , N(30%NO3+70% NH4)-P-K (15-5-30) , the first two week   N(60% NO3+40% NH4)-P-K (20-20-20) and later two week  N(30%NO3+70% NH4)-P-K...

Abstract Background Kidney disease and renal failure are associated with hospital deaths in patients COVID − 19. We aimed to test if contrast enhancement affects short-term function hospitalized 19 patients. Methods Plasma creatinine (P-creatinine) was measured on the day of computed tomography (CT) 24 h, 48 4–10 days after CT. Contrast-enhanced ( n = 142) unenhanced 24) groups were subdivided,...

BACKGROUND AND PURPOSE N-methyl-D-aspartate antagonists are effective in limiting ischemic damage to the brain and spinal cord if treatment is begun at time of ischemic injury. More clinically relevant delayed therapy has not been adequately investigated. We report the temporal profile of efficacy for two competitive N-methyl-D-aspartate antagonists in therapy of central nervous system ischemia...

conclusions in samples stored in plastic syringes, overestimation of pao2 levels should be noted if samples cooled before analysis. in samples stored in plastic syringes, it is not necessary to store samples in iced water when analysis delayed up to one hour. results pao2 of the samples stored at 0°c was increased significantly after 60 minutes (p = 0.007). the paco2 of the samples kept for 30 ...

PURPOSE This study examined the effects of exercise-induced fatigue on soccer skills performed throughout simulated match play. METHODS Fifteen academy soccer players completed a soccer match simulation (SMS) including passing, dribbling, and shooting skills. Precision, success rate, and ball speed were determined via video analysis for all skills. Blood samples were obtained before exercise ...

To assess the effects of mill operating parameters such as speed, ball filling, slurry concentration and filling on grinding process size distribution product, it was endeavored to build a pilot model with smaller than mill. For this aim, 1 m × 0.5 implemented. There are 15 lifters 50 mm height face angle 30˚. In present work, combination balls (40% 60 diameter, 40% 40 diameter 20% 25 diameter)...

AIMS ASSENT 3 (Assessment of the Safety and Efficacy of a New Thrombolytic) demonstrated that the bolus fibrinolytic tenecteplase (TNK), combined with enoxaparin (ENOX) or abciximab (ABCX), substantially reduced ischemic complications of acute myocardial infarction as compared with unfractionated heparin (UH). We compared ST resolution in each of the three treatment regimens in order to evaluat...
