Considerable degeneration of the endometriosis occurs after two months of medical treament, and symptoms should therefore diminish. Uncontrolled evidence suggests that laparoscopic ablation of endometriotic implants improves symptoms.'4 Successful surgical and medical treatments are both followed by an appreciable rate of ...

We prove that the dual or any quotient of a separable reflexive Banach space with the unconditional tree property has the unconditional tree property. Then we prove that a separable reflexive Banach space with the unconditional tree property embeds into a reflexive Banach space with an unconditional basis. This solves several long standing open problems. In particular, it yields that a quotient...
