These cells then synthesize and secrete the Sonic Hedgehog protein, which diffuses up through the tube, creating a 'concentration gradient'.
The ocean crust heats and releases its water, which diffuses upward and soaks into the earth's hot mantle.
We'll also start to notice our triggers more quickly, which diffuses their intensity.
He saw the Democrats' plan, which diffused some of the minority votes in urban centers, as more equitable.
which diffuse slowly and therefore cause inordinately long detection times.
It was observed that two adenomas were almost entirely necrotic, precluding immunohistochemical categorization and one adenoma, which showed strong diffuse staining for ACTH and GH and moderate scattered staining of LH and TSH, was considered indeterminate by immunohistochemical classification.
By contrast, variable patterns of CD151 expression were seen in the invasive breast cancer tissues, which ranged from absence to diffuse, strong overexpression occurred mainly in the membrane and/or cytoplasm of the tumour cells.
Some cases of PIN and carcinoma, however, display an attenuation of the Golgi staining and an additional diffuse strong cytoplasmic immunoreactivity, which was seen in 68 cases (11.1%).
Carico et al (2012) demonstrated that higher expression of E-cadherin was associated with specific subtypes of laryngeal cancer, such as in situ carcinoma, in which a strong and diffuse immunostaining pattern was observed.
Given the heterogeneous location in the same tumours, the intensity of signal and the distribution of staining were also evaluated on a six-tiered scale: negative, weak focal, moderate focal, weak diffuse, moderate diffuse, and strong diffuse.
