The orientation of a decellularized uterine scaffold determines the tissue topology and architecture of the regenerated uterus in rats†.

A decellularized uterine scaffold (DUS) prepared from rats permits recellularization and regeneration of uterine tissues when placed onto a partially excised uterus and supports pregnancy in a fashion comparable to the intact uterus. The underlying extracellular matrix (ECM) together with an acellular, perfusable vascular architecture preserved in DUS is thought to be responsible for appropriate regeneration of the uterus. To investigate this concept, we examined the effect of the orientation of the DUS-preserving ECM and the vascular architecture on uterine regeneration through placement of a DUS onto a partially defective uterine area in the reversed orientation such that the luminal face of the DUS was outside and the serosal face was inside.

Impact of borderline-subclinical hypothyroidism on subsequent pregnancy outcome in women with unexplained recurrent pregnancy loss.

Aim: Because subclinical hypothyroidism (thyroid-stimulating hormone [TSH] > 4.5 IU/mL) is associated with adverse pregnancy outcome, including early pregnancy loss, TSH is recommended to be titrated to ≤2.5 mIU/L in levothyroxine-treated women before pregnancy.

How to Create an Embryo Penetration Route.

Numerous past investigations into human implantation have tended to pay attention to the mechanism of embryo adhesion to endometrial cells or embryo invasion into endometrial stromal tissue. For successful pregnancy, however, embryo penetration through the endometrial epithelial cell (EEC) sheet is also absolutely required. To improve the performance of assisted reproductive technology, implantation studies should also focus on EEC dynamics, in particular, the action of EECs during embryo penetration.

Efficacy and safety of olanzapine combined with aprepitant, palonosetron, and dexamethasone for preventing nausea and vomiting induced by cisplatin-based chemotherapy in gynecological cancer: KCOG-G1301 phase II trial.

Purpose: Olanzapine is effective in chemotherapy-induced nausea and vomiting (CINV). In patients receiving highly emetogenic chemotherapy (HEC), its efficacy was reported as rescue therapy for breakthrough emesis refractory to triplet therapy (palonosetron, aprepitant, and dexamethasone). However, its preventive effects with triplet therapy for CINV are unknown.
