In New Jersey, Porcine zona pellucida is used to keep deer populations low, and this process is commonly referred to as " spay-vac ".

Porcine zona pellucida has been used in wildlife contraception since the late 1980s.

Porcine insulin is especially close to the human version.

Another limitation is the risk for transmission of zoonotic infections from pigs to humans, particularly from Porcine Endogenous Retro-Viruses ( PERV ).

Pig-Iron is also nicknamed the " Swine of Steel " and " Porcine Powerhouse ".

2009 compared transcriptional profiles using short-oligonucleotide microarrays ( Affymetrix Porcine GeneChip ) to survey differentially expressed genes between parthenotes ( 2 maternal genomes ) and control fetuses ( 1 maternal, 1 paternal genome ) An intriguing study surveying the transcriptome of murine brain tissues revealed over 1300 imprinted gene loci ( approximately 10-fold more than previously reported ) by Illumina RNA-sequencing ( RNA-Seq ) technology from F1 hybrids resulting from reciprocal crosses.

Porcine herpesviruses and rotaviruses can be eliminated from the donor pool by screening, however others ( such as parvovirus and circovirus ) may contaminate food and footwear then re-infect the herd.

* 2008. 121V. U Remove ( abolish ) 18 species ( Human enteric coronavirus, Human coronavirus OC43, Bovine coronavirus, Porcine hemagglutinating encephalomyelitis virus, Equine coronavirus, Murine hepatitis virus, Puffinosis coronavirus, Rat coronavirus, Transmissible gastroenteritis virus, Canine coronavirus, Feline coronavirus, Infectious bronchitis virus, Duck coronavirus, Goose coronavirus, Pheasant coronavirus, Pigeon coronavirus, Turkey coronavirus, Severe acute respiratory syndrome coronavirus ) from the genus Coronavirus

The Program for the Eradication of Porcine Swine Fever and for the Development of Pig Raising ( PEPPADEP ) caused widespread hardship among the peasant population, who bred pigs as an investment.

* Porcine parvovirus, a virus causes reproductive failure of swine.

Porcine parvovirus causes a reproductive disease in swine known as SMEDI, which stands for stillbirth, mummification, embryonic death, and infertility.

* 2008. 089V Assign three existing species ( Human coronavirus 229E, Human coronavirus NL63, Porcine epidemic diarrhea virus ) and five new species proposed in 2008. 091-095V. 01 to the proposed new genus Alphacoronavirus

* 2008. 122V. U Reassign species Human coronavirus 229E, Human coronavirus NL63 and Porcine epidemic diarrhea virus to the new genus Alphacoronavirus and Human coronavirus HKU1 to the new genus Betacoronavirus

As of April 5, 2011, Frito-Lay's online list " U. S. Products Made Without Pig ( Porcine ) Enzymes " catalogs nine flavors of Sun Chips " made and distributed in the U. S ." that do not contain porcine enzymes.

* Cortical reaction, occurs when a sperm cell unites with the egg's plasma membrane, altering the zona pellucida which prevents other sperm from binding to and entering the egg

Included in the follicles are the cumulus oophorus, membrana granulosa ( and the granulosa cells inside it ), corona radiata, zona pellucida, and primary oocyte.

The zona pellucida, theca of follicle, antrum and liquor folliculi are also contained in the follicle.

Then, a flat layer cell forms on the exterior of this cavity, and the zona pellucida, the blastocyst's barrier, remains the same size as before.

In 24 to 48 hours, the zona pellucida breaches.

Sperm activation has been shown to be caused by calcium ionophores in vitro, progesterone released by nearby cumulus cells and binding to ZP3 of the zona pellucida.

ZP3, one of the proteins that make up the zona pellucida, then binds to a partner molecule on the sperm.

Enzymes on the inner acrosomal membrane digests the zona pellucida.

After the sperm penetrates the zona pellucida, part of the sperm's cell membrane then fuses with the egg cell's membrane, and the contents of the head diffuse into the egg.

In order to prevent polyspermy and minimise the possibility of producing a triploid zygote, several changes to the egg's zona pellucida renders them impenetrable shortly after the first sperm enters the egg.

Prior to implantation, the embryo remains in a protein shell, the zona pellucida, and undergoes a series of cell divisions.

A morula ( Latin, morus: mulberry ) is an embryo at an early stage of embryonic development, consisting of cells ( called blastomeres ) in a solid ball contained within the zona pellucida.

Further development and registrations of porcine zona pellucida or PZP, another immunocontraceptive targeted for feral horses, is supported by HSUS.

These enzymes break down the outer membrane of the ovum, called the zona pellucida, allowing the haploid nucleus in the sperm cell to join with the haploid nucleus in the ovum.

It is in this period or in some cases at the beginning of sexual maturity that the primary oocytes secrete proteins to form a coat called zona pellucida and they also produce cortical granules containing enzymes and proteins needed for fertilization.

Meiosis stands by because of the follicular granulosa cells that send inhibitory signals through gap junctions and the zona pellucida.

As the sperm approaches the zona pellucida of the egg, which is necessary for initiating the acrosome reaction, the membrane surrounding the acrosome fuses with the plasma membrane of the oocyte, exposing the contents of the acrosome.

After the cumulus layer is penetrated, the acrosomal enzymes begin to dissolve and the actin filament comes into contact with the zona pellucida.

Glycoproteins on the outer surface of the sperm then bind with glycoproteins on the zona pellucida of the ovum.

Acrosin digests the zona pellucida and membrane of the oocyte.

In the mouse it has been demonstarated that ZP3, one of the proteins that make up the zona pellucida, binds to a partner molecule ( to the β1, 4-galactosyl transferase receptors ) on the sperm.

The main reasons are to prevent contamination with residual sperm adhered to the zona pellucida and to avoid unexpected fertilization failure.
