Article Synopsis
- Researchers examined the roles of prostaglandins (PGs) in the uterus by studying various PG receptor expressions during pregnancy, finding key receptors in luminal and stromal cells.
- The expression of the DP receptor was notably induced in stromal cells after embryo attachment, aligning with COX-2 expression, while both PGD and PGE were synthesized in significant amounts during implantation.
- The study revealed that the DP and EP4 receptors play crucial roles in the process of decidualization, with pharmacological interventions suggesting their coordinated functions despite the lack of impact from DP/EP2 double deficiency.
We investigated a case of a peripherally inserted central venous catheter associated with iliolumbar venous extravasation in an infant. Hyperosmolar infusion and calcium gluconate caused phlebitis and vascular perforation. Daily monitoring of the catheter length at the insertion site and serial radiography may aid in detecting catheter movement.

Case Presentation: A female neonate was delivered by cesarean section at 31 weeks of gestation. Her birth weight was 1538 g and Apgar scores were 6 at both 1 and 5 min.
The DNA repair protein O (6)-methylguanine-DNA methyltransferase (MGMT, AGT) is a determinant of the resistance of tumor cells to alkylating anticancer agents that target the O(6) position of guanine. MGMT promoter methylation in tumors is regarded as the most common predictor of the responsiveness of glioblastoma to alkylating agents. However, MGMT promoter methylation status has been investigated mainly by methylation-specific PCR, which is a qualitative and subjective assay.

The news spread all around Japan and induced fear that workers at incinerators would suffer from cancer or other serious illness induced by the exposure to dioxins. Authors were interested in the effect of this stressful event occurred to the workers and intended to evaluate mental health status of MSWI workers compared with office workers.
