This study aimed to investigate the exercise habits of pregnant women in the third trimester (N = 303). We assessed participation in physical activities, including exercise or sports, using the Japanese version of the Pregnancy Physical Activity Questionnaire. A total of 183 (60.4%) pregnant Japanese women participated in some form of exercise and 87 (28.7%) exercised for 2 hours or more, per w...

In order to prevent and control the disease, it is important to know the extent of the complications. The aim of this study was to investigate the relationship between pregnancy-induced hypertension with neonatal and maternal complications.   Materials and Methods This prospective, descrip...

Previous studies have revealed correlations among prepregnancy body mass index (BMI), gestational weight gain and the birth weight of the infant. However, as a variety of indices relating to the physique have been used to assess the optimal weight of pregnant women, no conclusions have yet been established regarding the Japanese population. Therefore, the aim of this study was to analyze the co...

History: Placental tissues submitted were from a 12-year-old, multiparous, Quarterhorse mare. The mare produced a live foal in 2006. The mare was pregnant in 2007 with a thickened placenta detected by ultrasound at 290 days of gestation. The animal was treated medically for placentitis and delivered a live foal naturally at 310 days of gestation. The placenta was submitted for laboratory analysis.

A majority of C57BL/10Sn females pregnant six or more times by syngeneic males do not reject male skin grafts. The pregnancy induced tolerance of male skin grafts was transferred adoptively to virgin recipients by thymus-dependent cells from multiparous tolerant donors.

Lactation is the most energy demanding part of parental care in mammals, so parent-offspring conflict arises over milk provided by the mother. In some species females commonly become pregnant shortly after parturition of previous young. This further intensifies mother-offspring conflict due to concurrent pregnancy and lactation. In equids it has been well established that pregnant females wean ...

To compare 2 strategies for systematically resynchronizing ovulation, lactating Holstein cows (n = 763) at various days in milk and prior artificial insemination services were assigned randomly at timed AI (TAI) to receive the first GnRH injection of Ovsynch 26 (D26) or 33 (D33) d after TAI to resynchronize ovulation (Resynch) in cows failing to conceive. Cows in the D26 treatment received GnRH...

BACKGROUND The association of grand multiparity and poor pregnancy outcome has not been consistent for decades. Classifying grand multiparous women as a high-risk group without clear evidence of a consistent association with adverse outcomes can lead to socioeconomic burdens to the mother, family and health systems. We compared the maternal and perinatal complications among grand multiparous an...
