Technetium-99m sulfur colloid ( mTc-SC) has been useful in reticuloendothelial imaging, and in particular in liver/spleen and more recently bone marrow scintigraphy. Technetium99m SC can also be employed to localize acute gastrointestinal bleeding and has been used in lung ventilation studies. The standard radiolabeling method requires a heating period in a boiling water bath. A comparison of a...

component type C plugs into architecture Figure 1. Concept of Abstract Component Specification Now, suppose that there are one or more concrete components K1...Kn that can potentially be used with A as a component that satisfies C, as shown in Figure 2. For this to be semantically viable, the specification of a Ki, SKi must be compatible with SC (i.e., SKi implies SC) and Ki must be a faithful ...

Microbially induced concrete corrosion (MICC) is an important problem in sewers. Here, small-subunit (SSU) rRNA gene amplicon pyrosequencing was used to characterize MICC communities. Microbial community composition differed between wall- and ceiling-associated MICC layers. Acidithiobacillus spp. were present at low abundances, and the communities were dominated by other sulfur-oxidizing-associ...

Biogenic Sulfur Compounds, Gas Chromatography, Concrete Corrosion Pseudomonasßuorescens, Proteus vulgaris, and Serratia marcescens, members o f the microflora of soil and waste water, attacked methionine in the presence o f glucose. The sulfur o f m ethionine was released as methane thiol, dimethyl sulfide and dimethyl disulfide. The volatile sulfur com ­ pounds were qualitatively and quantitat...

Objective: The purpose of this study was to retrospectively evaluate microwave heating preparations of "'Tc-sulfur colloid during a 4-wk period. Methods: The mTc-SC kit preparation was performed according to the package insert with microwave heating modifications. Results: During the first 2 wk, patient studies (n = 14) showed excellent images, however during the last 2 wk patient studies (n = ...
