Heterotopic pregnancy (HP) is the simultaneous occurrence of intra- and extrauterine pregnancies. It is a rare event in spontaneous pregnancies with an incidence of less than 1:15000 however the frequency has increased to 1% in accordance with the widespread use of assisted reproductive techniques (ART). The pre-operative diagnosis of this condition is generally difficult and it would be life t...

This Application Note demonstrates the capability of the Agilent 1290 Infi nity 2D-LC Solution for heart-cutting applications. As an example, a minor impurity is resolved by heart cutting from a co-eluting main compound. The minor impurity, which is isolated on a second-dimension column after heart cutting, is verifi ed by additional spiking and statistical evaluation of the separation performa...

The physiologic importance of the endometrium in assisted reproductive technology is now receiving much research attention. The historical importance of ultrasound for determination of endometrial pattern, thickness and contractility is reviewed and speculation provided for a possible mechanism of the adverse effect of thin endometrium on implantation.
