Their behavior in contact with biological fluids, cells, and tissues rules their suitability for a range of applications, which include bearings of joint prostheses, bone fillers, porous scaffolds, and coatings.
Because the presence of mRNA coding for Runx2 has already been demonstrated in the perichondrium and periosteum of several amphibian species [ 15, 41, 42], the absence of VDR in these tissues rules out the possibility of a functional interaction between the two proteins.
Yet the pain and loss that do come will come regardless of our "musts" and "can'ts" -- which only delude us into thinking that this tissue of rules will somehow hold back life's tide.
McKnight and collaborators conducted a study with H-MRSI to identify a CNI that predicted tumour tissue and ruled out normal tissues [ 16].
The 32,624 genes obtained that were present in normal tissues were ruled out, following which, the 2000 genes that showed a high ND/low ND ratio equal to, or greater than twofold were identified.
He told me he would have to operate to take out the offending tissue and rule out breast cancer.
The Food and Drug Administration has tissue-banking rules that apply to sperm banks, but those rules concern infectious diseases rather than genetics, and do not limit the number of pregnancies per donor or require tracking of the children's health.
Immunohistochemistry for markers of prostatic tissue to rule out prostatic cancer, i.e. prostate-specific antigen (PSA) and prostate-specific acid phosphatase (PSAP), were both negative.
On the other hand, the opening of the fistulous tract in the perianal skin epidermis did not contain signs of inflammation or malignant tissue, which ruled out the possibility of the fistula being a complication or a secondary manifestation of a cutaneous melanoma [ 14].
This previous polyclonal anti-progerin did not detect progerin in normal tissue, and to rule out the possibility of the antibody being of low affinity or that the recognized epitope might be masked, we generated a rabbit monoclonal antibody using the same peptide as antigen as described in Materials and Methods [30].
