The validation of ovarian cancer data could not be performed due to the unavailability of comparable expression datasets.
Due to the unavailability of gene expression data from matched normal samples from the cancer patients examined, we utilized as controls, the results of assays carried out on normal ovarian tissues collected from eight healthy (age matched) women.
We found no correlation in the 115 consensus genes between the E2 deprived and cycling MCF-7 cells and were unable to compare with cycling ZR75-1 cells due to the unavailability of SAGE/MA gene expression data.
Though it would be straightforward, even for more complex DE systems, to relate observed maximal/minimal production levels to steady-state conditions, some difficulties arise in evaluations of experts on reaction speeds with a given more complex model due to unavailability of the analytical expression for the reaction speeds.
The expression of the I. multifiliis surface protein in T. thermophila is promising [ 76], but the unavailability of a commercial ciliate expression vector and transformation host as well as the special transformation method required (DNA bombardment) may hinder routine ciliate expression studies.
The design of experiments for discrete mixed effect models is challenging due to the unavailability of a closed-form expression for the Fisher information matrix (FIM), on which most optimality criteria depend.
Informal payments, the rate of absenteeism, the unavailability of health workers, and the expression of authority over patients are the main issues highlighted by communities: "When you go to pay for drugs at the pharmacy, they cheat all your money.
The unavailability of information concerning the normal PR expression in cat endometrium limits the interpretation of the decrease in the PR stromal expression during LS.
Due to the muscle-specific expression of HspB2 and the unavailability of appropriate antibodies recognizing mouse HspB2, we did not examine its expression in the mouse brain.
High rates of absenteeism for health workers in health centres and their unavailability and the expression of authority towards patients are " routine practice" in daily health care.
