T2 and T1rho MRI in articular cartilage systems.

T2 and T1rho have potential to nondestructively detect cartilage degeneration. However, reports in the literature regarding their diagnostic interpretation are conflicting. In this study, T2 and T1rho were measured at 8.

Sex hormone effects in non-pregnant rat and human myometrium.

Objective: To study effects of sex hormones on spontaneous contractility and on the effects of depolarizing agent potassium chloride (KCl), M-cholinoceptor and prostaglandin receptor agonists on non-pregnant rat and human uterine tissues.

Study Design: Uterine rings from ovariectomized rats treated with sex hormones or placebo, and uterine strips from premenopausal and postmenopausal women were equilibrated in Krebs buffer (t=37 degrees C, pH approximately 7.4) for isometric tension recordings.
