The objective of the present study was to determine whether oestrous detection with the help of oestrous detection aids during the Heatsynch without timed AI protocol is equally effective with the progesterone-combined protocol in dairy heifers. A total of 148 heifers were randomly assigned to one of the two groups. A group of heifers treated with Heatsynch with heat detection aids (n = 72) rec...

New technology was used to identify traces of a commercial barrier/spermicide in evidence from a case of a man accused of rape of a minor. Examination of vaginal swabs performed by another laboratory had been negative for seminal fluid or other sources of DNA from the suspect and we were asked to examine the remaining swabs for any traces that might have originated from the commercial product. ...

Background Patients with arrested preterm labor (PTL) are at increased risk for recurrence of preterm birth (PTB). Maintenance tocolysis after arrest of acute PTL is of questionable value. The objective of this study was to evaluate the efficacy of 200 mg vaginal progesterone in order to prevent PTB in women with episodes of threatened PTL. MaterialsAndMethods This is a randomized double blind ...

BACKGROUND In a previous study, progesterone treatment of female monkeys immunized with live, attenuated SHIV89.6 abrogated the generally consistent protection from vaginal simian immunodeficiency virus (SIV) challenge. The mechanisms responsible for the loss of protection remain to be defined. The objective of the present study was to determine whether Depo-Provera administration alters protec...

Goreisan suppository is prepared as a hospital preparation, and successfully used for the treatment of diarrhea and vomiting in young children with common cold. While clinical efficacy of the suppository has been reported, few studies have been carried out to clarify the preparation procedure and pharmacokinetics of the suppository. In this study, trans-cinnamic acid (CA) was used as a represen...

BACKGROUND Premature birth is considered one of the main problems in modern Obstetrics. It causes more than 50 % of neonatal mortality; it is responsible for a large proportion of infant morbidity and incurs very high economic costs. Cervical length, which can be accurately measured by ultrasound, has an inverse relationship with the risk of preterm birth. As a result, having an effective inter...

The objective of the experiment was to compare pregnancy rates resulting from fixed-time AI after administration of either 1 of 2 controlled internal drug release (CIDR)-based protocols. Heifers at 3 locations (location 1, n = 78; location 2, n = 61; and location 3, n = 78) were assigned to 1 of 2 treatments within reproductive tract scores (1 = immature to 5 = cycling) by age and BW. Heifers a...
