In contrast, washing betel leaf sample with 0.01% CCa, 0.5% (H2O2), and 0.5% CA was able to eliminate pathogenic bacteria initially, however, after enrichment the pathogen populations were detected in the commercial betel leaf samples.
Even a small amount of microvascular damage can be detected by cardiovascular magnetic resonance (CMR) as microvascular obstruction (MVO) which is defined as a dark zone with impaired contrast wash-in within the high-signal-intensity infarcted region on early (3 5 min after contrast injection) or late (>10 min post-contrast) gadolinium-enhanced images [ 5].
Metastatic lesions were considered those solid lesions showing contrast wash-out in the portal phase, thus becoming markedly hypoechoic or even anechoic in the late phase (Fig. 1, 2), regardless of the type of arterial phase pattern, in accordance with accepted criteria [ 22].
This contrast washes out of tumor regions quickly, leading to a steep wash in-wash out enhancement curve.
In terms of the sustainability in a slow flow environment, foam contrast washed out much more slowly than a conventional contrast.
In contrast, washing the assay plates with Tween 20 or Tween 80 decreased the apparent titers in serum from the rabbit immunized with mPEG-uricase only c. 8-fold or c. 5-fold, respectively (black arrows).
The contrast agent wash in and wash out were recorded for 60 seconds.
Six hours were chosen to allow enough time for the contrast to wash out between scans, while minimizing the time between scans for patients' physiological parameters or imaging characteristics to alter.
After the injection of contrast medium (wash in phase, Figure 1B) an increasing echogenicity in the hepatic arteries was initially observed, followed by a more diffuse and homogenous enhancement of the liver parenchyma during the portal phase, until the peak intensity was reached.
