The phrase "as a substrata" is not commonly used in written English and may be considered incorrect in certain contexts.
It can be used when referring to a foundational layer or underlying basis in a discussion, particularly in academic or technical writing.
Example: "The theory was built upon several key principles, with the concept of cultural identity serving as a substrata for understanding social dynamics."
Alternatives: "as a foundation" or "as an underlying layer".
In the central parts of Anatolia, within the bend of the Halys River (now called the Kızıl River), and in the northern regions, Hittite and Palaic were influenced by Hattian as a substratum language.
At the beginning of her Vagina book, Wolf says that her theory of "biological consciousness" comes in part from William James's mighty The Variety of Religious Experience (1902) – "the issue of neurology as a substratum for these common mystical experiences", ie, that particular brain-states may give people a feeling that they are, for a moment, in touch with God.
Considerably fewer reports are available on the use of sericin as a substratum or scaffold for growing cells and tissues.
We have previously shown that fibroin can function successfully as a substratum for growing cells of the eye.
We aim at extending the range of sericin's potential use as a substratum or scaffold for cells in ophthalmic tissue engineering.
These differences are statistically significant and provide compelling evidence of the suitability of BMSS as a substratum for the growth of HLECs.
In the present report, we investigated the capacity of sericin regenerated from B. mori cocoons to function as a substratum for cell growth, either as such or blended with regenerated fibroin.
In an early study (Minoura et al. 1995b), BMSS harvested directly from the silk gland was evaluated as a substratum for mouse fibroblasts (line L-929), alone or blended with fibroin.
We report the first successful growth of primary human corneal endothelial cells on coated fibroin as a step in evaluating fibroin as a substratum for the transplantation of tissue-constructs for endothelial keratoplasty.
The ability of BMSS, either directly extracted from MSG or regenerated from cocoons, to function as a substratum for cell growth was latter confirmed by others (Terada et al. 2002; Tsubouchi et al. 2005; Xie et al. 2007; Aramwit et al. 2009b,2010).
