4D-US is superior over real-time two-dimensional ultrasound (2D-US) for qualitative, but inferior for quantitative analysis of hand movements. Thus 4D-US makes it possible to determine exactly the direction of the fetal hand, but the exact number of each type of hand movements can still not be determined. 4D-US is superior over two- and three-dimensional sonography in the evaluation of complex facial activity and expression. Among facial activities observed by 4D-US, simultaneous eyelid and mouthing movements dominate between 30 and 33 weeks of gestation. Pure mouth movements such as mouth opening, tongue expulsion, yawning and pouting are present, but at a significantly lower incidence. Facial expressions such as smiling and scowling can be precisely observed using 4D-US.
4D ultrasound enables visualization of more details of the dynamics of small anatomical structures. Therefore, body and limb movements can be visualized a week earlier than with 2D.
The concentrations of progesterone receptors in endometrial tumors of 160 patients were analyzed with respect to survival and presence of clinicopathologic prognostic factors. The concentration of 25 fmol/mg of proteins for progesterone receptors appeared to be most powerful for prediction of survival. The survival was also significantly correlated to age, depth of myometrial invasion and clinical stage of the tumor. Concentration of estrogen receptors could not be correlated with the probability of patients' actuarial survival.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
