PURPOSE To investigate the effect of low tube voltage (80 kV) on image quality, radiation dose, and low-contrast detectability (LCD) at abdominal computed tomography (CT). MATERIALS AND METHODS A phantom containing low-contrast objects was scanned with a CT scanner at 80 and 120 kV, with tube current-time product settings at 150-650 mAs. The differences between image noise, contrast-to-noise ...

Labeling of metastatic tumors can aid in their staging and resection of cancer. Near infrared (NIR) dyes have been used in the clinic for tumor labeling. However, there can be a nonspecific uptake of dye by the liver, lungs, and lymph nodes, which hinders detection of metastasis. In order to overcome these problems, we have used two NIR dyes (DyLight 650 and 750) conjugated to a chimeric anti-c...

The study compared the mechanical properties of human bone, fresh bovine bone and a new highly purified bone xenograft: T650 (Lubboc-Laddec). Destructive, compressive tests were performed to determine Young's modulus and ultimate strength, with a constant deformation rate of 0.025 mm min-1. The stress-strain curves obtained from all the non-human specimens especially the T650, did not differ si...

In the present study, 12 aerobic bacterial strains were isolated from the common effluent treatment plant (CETP) of tannery industries and identified as Alcaligenes sp. (FJ55942), Pantoea sp. (FJ55943), Bacillus megaterium (FJ55944), B. marisflavi (FJ55945), B. subtilis (FJ55946), B. megaterium (FJ55947), B. cereus (FJ55948), B. pumilus (FJ55949), Pseudomonas sp. (FJ55950), Bacillus sp. (FJ5595...

Abstract Study question Whether follicular extracellular vesicles of older women interfere with the quality oocytes. Summary answer OLD-EVs induced oxidative stress in oocytes and inhibited oocyte maturation by increasing abnormal mitochondria distribution spindle rates. What is known already Ovary a critical regulator female fertility source With modern tendency delaying childbearing, ovarian ...

Abstract A model Si-free alloy, Fe-30Cr (wt.%), was exposed to Ar-10H 2 O mixture (in vol.%) at 650 °C, forming a protective Cr 3 scale, which contained silica. Liquid water used form vapour in bubbler either deionised or distilled. In both cases, low-level impurities of Si, F, Cl, S, and Ca matched those detected the scales by TEM/EDX ToF–SIMS. Consideration droplet residual solute particle si...
