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.

A system and method is disclosed for recommending venues and events to individual users using a combination of collaborative filtering and integrating social behavioral pattern data gathered and computed via an electronic device. The system and method of the present invention is configured to receive data based on users' past, present and future social activity and interests, which are submitted to the system via an electronic device. When a new data item is made available from sources such as a mobile device, social networks or GPS systems, the system and method analytically breaks down the new item data, compares it to ascertained attributes of item data that a user (i.) indicated interest to in the past, (ii.) has a friend or related network of users that indicated interest in the venue or in an event in the past, and (iii.) indicated interest in the event or venue based upon general social statistics such as male to female ratio, age, and other demographics gathered and computed by the system. The system generates the recommendations using a previously-generated table which maps items to lists of “similar” items thereby making a audience-specific, time-specific and location-specific social recommendation.

The present invention relates the function of Dickkopf 3 (Dkk3 ) in testis using shRNA mediated knock down model. Specifically, the present invention provides knock down model comprising reduction in Dkk3 activity. The knock down model of Dkk3 consisting of non human vertebrates which have, incorporated in their genome, shRNA construct targeting mammalian Dkk3 gene exhibits low testis weight, low sperm count and has low litter size. The knock down model displays disrupted seminiferous tubules and are subfertile. The present invention model has a role in sex determination as its interruption leads to sex reversal of XY gonads, converting males to females. Sex reversal role of Dkk3 knock down model can find its utility in agricultural applications. The present invention describes Dkk3 as a dual function protein which is associated with sex determination as well as is essential for the process of spermatogenesis. Such testicular functional studies are useful as a model for various disease states of infertility or subfertility and for identifying a potential treatment to overcome idiopathic infertility.
