Temporal optimization of meiotic arrest for enhancing oocyte maturity during in vitro maturation of porcine median antral follicles.

During in vitro maturation (IVM), median antral follicles (MAFs) were mechanically aspirated from the porcine ovarian cortex, and this process causes an early disconnection of follicular somatic cells from oocytes within antral follicles before the formation of graafian follicles. Thus, nuclear maturation is accelerated ahead of the completion of cytoplasmic maturation. Dibutyryl-cAMP (dbcAMP), a well-known cAMP modulator, is used to inhibit the resumption of meiosis in immature oocytes.

Real-time optical detection of endodontic infection using bacterial autofluorescence.

Objectives: For successful root canal treatment (RCT), it is essential to objectively assess the presence and activity of bacteria in the root canal system. However, current methods rely on subjective observations of root canal exudates. This study aimed to confirm whether real-time optical detection using bacterial autofluorescence can evaluate endodontic infection status by assessing the red fluorescence (RF) detected from root canal exudates.

Effects of cumulus cells on the in vitro cytoplasmic maturation of immature oocytes in pigs.

The exposure of cumulus cells to nuclear matured oocytes can be regulated through the forced delay of nuclear maturation or the alteration of in vitro maturation (IVM) time in cumulus-oocyte complexes (COCs). However, to date, no evidence has been presented for the enhancement of cytoplasmic maturation by them, indicating irrelevance of cumulus cells in cytoplasmic maturation. Therefore, in order to identify the requirement of cumulus cells in achieving the cytoplasmic maturation of immature oocytes, this study investigated the effects of cumulus cells on the in vitro cytoplasmic maturation of oocytes within COCs derived from porcine medium antral follicles (MAFs) post-the completion of nuclear maturation.
