By M iiTIN J. CLINE AND NATHANIEL I. Bi ur. G RAY AND STERLING demonstrated that red cells can bind radioactive sodium chromate ( Na2 Cr51O4 ) in vitro rapidly and without apparent damage to the exposed cells.’ The chromium-51 labeling technic was rapidly adopted for the measurement of total red cell volume and red cell life span.26 As an erythrocyte label it possesses the advantage that it is ...

Elution is a procedure for recovery of antibody attached to intact,immunoglobulin-coated red blood cells (RBCs) by disrupting the antigen-antibody bonds. The recovered antibody is collected in an inert diluent and is referred to as an eluate. Testing of an eluate may be desired to identify antibody(ies) coating the RBCs of patients with a positive direct antiglobulin test. Many types of elution...

Dental alloys for direct metal laser sintering (DMLS) are available on the market today, but there is little scientific evidence reported on their characteristics. One of them is the release of ions, as an indicator of the corrosion characteristics of a dental alloy. Within this research, the difference in the elution of metals from DMLS and cast (CM) samples of Co-Cr-Mo dental alloy in saliva-...

A gradient elution high performance liquid chromatography method with detection at 230 nm for the analysis of perbenzoylated cerebrosides containing hydroxy and nonhydroxy fatty acids is described. The quantitative range of the method is 0.5-10 nmol of cerebrosides. The limit of detection for injected sample is about 10 picomol. The analysis time by liquid chromatography is less than 5 minutes ...

High-dose antibiotic-loaded acrylic cement (ALAC) is used for managing peri-prosthetic joint infections (PJIs). The marked increase in resistant high-virulence bacteria is drawing the attention of physicians toward alternative antimicrobial formulations loaded into acrylic bone cement. The aim of this in vitro study was to determine the elution kinetics of 14 different high-dose ALACs. All ALAC...

The aim of this study was to evaluate the effect of four different storage media on the elution of monomers from two composite materials. Samples (n = 10, diameter: 4.5 mm, thickness: 2 mm) of two different composite materials (Ceram X™ & Filtek™ Supreme XT) were stored after polymerization in four different media (NaCl, saliva, ethanol 75% & acetone) for 24 h, 7 days, and 28 days. From the sto...

objective: medically unexplained symptoms are physical symptoms, which cannot be explained by organic ‎causes. this study aimed to investigate mental health in patients with medically unexplained ‎physical symptoms. ‎ method: one hundred outpatients who were admitted to the electro diagnosis clinic of imam khomeini ‎hospital, ahvaz/iran, participated in this study. data were collected using phy...

the electro discharge machining (edm), one of the methods used in the machining industry and a non-traditional manufacturing method, the electro erosion process does not depend on the hardness of material and offers a way to process materials of very complex geometry with very fine and high precision by using cheap electrode materials, which make it a preferred method. in this study, effect of ...
