  • Role of IL-8 and TIMP-2 on term canine trophoblast migration, invasion, and proliferation

    Creator:
    Gullaba, Justine Marie
    Abstract:
    Placental pathologies are not uncommon in dogs. For example, in primiparous bitches, the reported incidence of subinvolution of placental sites is 21% - 100%. Despite years of research in multiple species, the mechanisms regulating late gestation trophoblast behavior in the dog remain unexamined. Therefore, the objective of this study was...

  • Reproductive Effects of PG-600 Administration in Ewes

    Creator:
    Habeeb, Hayder
    Abstract:
    Sheep are seasonally polyestrus, which means they do exhibit estrus and ovulation during the short daylight (breeding season) and do not during the long daylight (nonbreeding season). To stimulate the ewes to ovulate during the nonbreeding season, various hormonal treatments have been used. PG-600 contains both equine chorionic gonadotropin and...

  • Sperm acrosome associated 3 protein expression and antigenicity in horses

    Creator:
    Cozzi, Brynley C.
    Abstract:
    Sperm acrosome associated 3 protein (SPACA3) is a unique, intra-acrosomal, conventional-type lysozyme-like protein of mammalian spermatozoa. SPACA3 is present in all stages of ovarian follicles and is localized to granulosa cells and ooplasma in humans, mice, cows, dogs, and cats. The objective of this study was to determine if equine...

  • Applications of GnRH immunization in domestic dogs

    Creator:
    Donovan, Caitlin Elizabeth
    Abstract:
    Reproductive function in the dog is controlled by feedback mechanisms that involve the hypothalamus, the anterior pituitary gland, and the gonads. Surgical gonad removal, a common procedure performed in dogs for the purposes of sterilization, disrupts the hypothalamic-pituitary-gonadal (HPG) axis and results in permanently elevated concentrations of gonadotropins. Manipulation of...

  • Luteinizing Hormone Receptor Expression in Canine Lymphoma, Mastocytoma, and Hemangiosarcoma

    Creator:
    Zwida, Khawla H.
    Abstract:
    Luteinizing hormone (LH) stimulates the secretion of gonadal steroid hormones (testosterone in males and estrogen/progesterone in females) and is under negative feedback from gonadal hormones. In gonad-intact dogs, LH is secreted in low amplitude pulses of concentrations under 1 ng/mL; except for the day of the LH surge in females...

  • Gene expression in the peripartum canine placenta

    Creator:
    Fellows, Elizabeth Jane
    Abstract:
    This research investigated gene expression in the canine placenta during the peripartum period. Previous studies have recognized molecular changes that occur in the placenta around the time of placental release in other species, but no study has looked at gene expression in the late gestation canine placenta. Of particular significance...

  • Matrix metalloproteinase type-2 and type-9 immunoexpression in bovine caruncular tissue at the time of calving, 2 hours post-calving, and 4 hours post-calving

    Creator:
    Gentle, Lauren and Kutzler, Michelle
    Abstract:
    As bovine parturition nears, the placentome undergoes changes that allow placental delivery within 12 hours after calving. These changes include the expression of enzymatic proteins (e.g. MMPs) within the placentome that are capable of breaking down collagen, allowing for the separation of the cotyledon from the caruncle. Dysregulation of either...

  • Fatty acid composition of the yolk sac membrane in the chicken embryo

    Creator:
    Neumann, Persia, Vercese, Francine, Cherian, Gita, and Kutzler, Michelle
    Abstract:
    Similar to the mammalian placenta with the chorioallantois and amnion, the avian yolk sac membrane (YSM) is comprised of the area vitellina (AVI) and area vasculosa (AVA), respectively. Understanding incorporation and delivery of nutrients (especially fatty acids) between these membranes and the developing embryo is important for improving hatchability and...

  • Canine LH Receptors Expression in Non-neoplastic and Neoplastic Tissues

    Creator:
    Zwida, Khawla
    Abstract:
    Throughout most of the developed world, surgical sterilization via gonadectomy has become a common tool for combating the overpopulation of unwanted dogs as well as to eliminate the risk of reproductive diseases in pet dogs. In the dog as in other normal adult mammal, the hypothalamus secretes gonadotropin-releasing hormone (GnRH),...

  • Histologic and Morphometric Evaluation of Testes of Feral Tom Kittens and Cats

    Creator:
    Bohrer, Ellie R., Mihalyo, Anna, and Kutzler, Michelle
    Abstract:
    Background: Even with numerous successful Trap-Neuter-Release programs, feral cat populations continue to grow. Our laboratory is interested in determining if an underlying biological cause exists for the exuberant reproductive success in this once domestic subspecies. An earlier age for developing reproductive capacity (onset of spermatogenesis in males) may be one...
