Porcine circovirus-2 (PCV-2) is a recently identified agent wherein the potential spectrum of PCV-2-associated disease has been expanded by evidence of vertical and sexual transmission and associated reproductive failure in swine populations. PCV-2 was isolated from a litter of aborted piglets from a farm experiencing late term abortions and stillbirths. Severe, diffuse myocarditis was present in one piglet associated with extensive immunohistochemical staining for PCV-2 antigen. Variable amounts of PCV-2 antigen were also present in liver, lung and kidney of multiple fetuses. Inoculation of female pigs with a composition including an immunogen from PCV-2 or an epitope of interest from such an immunogen or with a vector expressing such an immunogen or epitope of interest prior to breeding, such as within the first five weeks of life, or prior to the perinatal period, or repeatedly over a lifetime, or during pregnancy, such as between the 6th and 8th and/or the 10th and 13th weeks of gestation, can prevent myocarditis, abortion and intrauterine infection associated with porcine circovirus-2. In addition, innoculation of male and/or female pigs with the aforementioned compositions can be carried out to prevent transmission of PCV-2 from male to female (or vice versa) during mating. Thus, the invention involves methods and compositions for preventing myocarditis, abortion and intrauterine infection associated with porcine circovirus-2.

By exploiting an early release facility that may be provided by certain transactional memory designs, we allow for transaction software constructs that wait on removal (or satisfaction) of a condition that would otherwise result in transaction abort. Absent exploitation of such a such a facility, the act of checking the condition would typically introduce a corresponding location into the read set of the transaction, and a subsequent modification of that location that removed (or satisfied) the condition, would result in abortion of the blocked transaction. By exploiting an early release facility such as described herein, a transaction may release the location (or locations) corresponding the condition, retry, and once the transient condition is removed (or satisfied), complete and commit. In this way, computation effort may be conserved while still employing a conceptually simple and convenient coordination facility.

The present invention relates to a novel method of determining the existence of a normal pregnancy which has a high likelihood of culminating in a term pregnancy, by measuring hyperglycosylated hCG in a pregnant woman and comparing the concentration of measured hyperglycosylated hCG with a predetermined value. A measurement of hyperglycosylated hCG above the predetermined value, for example, about 13 ng/ml, is evidence of a high likelihood of a normal pregnancy. A measurement below the predetermined value is evidence of an abnormal pregnancy (ectopic pregnancy or miscarriage). Further analysis of the patient in the event that the measurement falls below the predetermined value is made by intravaginal or abdominal ultrasound to determine whether or not the pregnancy is ectopic or will likely result in a spontaneous abortion (miscarriage). This point-of-care (POC), over-the-counter (OTC) or professional laboratory application is unexpectedly rapid and highly predictive of pregnancy outcome in women exhibiting symptoms of pregnancy.
