Our findings based on the results of the relative rate ratio test and maximum likelihood analysis suggest that each round of gene duplication is characterized by adaptive evolution, although instances of evolution under positive selection have been found also long after divergence of gene families.
Desmoplastic small round cell tumor (DSRCT) is characterized by the presence of a fusion protein EWS/WT1, arising from the t (11 22 p13 q1212) translocation.
The golden mountain does not exist, yet we can say that it is both golden and a mountain since these are the properties in terms of which the object is characterized; similarly, the round square is both round and square, even though it cannot exist.
The first round of spermatogenesis in mammals is characterized by the synchronized appearance of particular cell types at different stages of the spermatogenic cycle among the seminiferous tubules, and this model was used to analyse differential gene expression during spermatogenesis [ 18, 19].
Family Hipposideridae, known as the Old World leaf-nosed bats, is characterized by a round nose leaf consisting of a horseshoe-shaped forward leaf, various accessory leaves, and an upright leaf.
At MR imaging, fresh fat necrosis is characterized by a round or irregular mass with central high-signal intensity on nonfat-suppressed unenhanced T1W images and high signal on T2W images, and exhibits variable enhancement following administration of gadolinium contrast material.
The luminal cell population is characterized by its round or oval shape with lightly stained nucleus harboring distinct nucleoli.
ILC is characterized by small, round cells that are bland in appearance and have scant cytoplasm, which infiltrate the stroma in single file and surround benign breast tissues in a targeted manner [ 1, 4].
Cushing syndrome is characterized by obesity, rounding and reddening of the face, high blood pressure, diabetes mellitus, osteoporosis, thinning and easy bruising of the skin, muscle weakness, depression, and, in women, cessation of menstrual cycles (amenorrhea).
The CPE of BHV-1 is characterized by cell rounding and ballooning, forming grape-like clusters of spherical cells gathered around a gap in the monolayer.
