Evaluation of the Harmonic Scalpel for Laparoscopic Bilateral Ovariectomy in Standing Horses
… technique for performing laparoscopic bilateral ovariectomy in standing horses. Study Design - Experimental study. Animals or Sample population - 8 mares, age 2-20 years, weight 410-540 kg. Methods - Standing laparoscopic bilateral ovariectomy was performed in 8 mares with normal anatomy of the …

Gingival MSCs Improve Bone Phenotype in Ovariectomy-Induced Osteoporosis via Programmed Cell Death Pathway
… but their effect on the bone phenotype of ovariectomy-induced osteoporosis hasn’t been explored. In our study, we show that a single systemic infusion of GMSCs elevated the bone mass reduction caused by Ovariectomy (OVX)-induced osteoporosis in both the femurs and mandibles of OVX mice, …

The Role of Exogenous Somatotropin, Ovariectomy and Extracellular Matrix in Bovine Mammary Gland Development
… with either exogenous GH or subjected to ovariectomy (OVX). Mammary parenchyma (PAR) and mammary fat pad (MFP) were harvested for DNA, protein, lipid, and western blot analysis. Remaining tissues were preserved for histological staining or snap frozen for quantitative real-time PCR. We …

A Study of the Effects of Ovariectomy and Ovarian Hormone Replacement Therapy on Carbohydrate Metabolism in Mice
This thesis examines the effects of long-term ovariectomy and ovarian hormone replacement therapy on the regulation of glucose homeostasis and certain aspects of lipid metabolism in adult female mice. Long-term (15 weeks) ovariectomy increased body weight, food intake and intestinal glucose …

Functional contributions of a sex-specific population of myelinated aortic baroreceptors in rat and their changes following ovariectomy
… changes, if any, loss of sex hormones through ovariectomy brings upon such functions. We assessed electrophysiological and reflexogenic differences associated with the left aortic depressor nerve (ADN) from adult male, female, and ovariectomized female (OVX) Sprague-Dawley rats. Our results …

Effects of Ovariectomy and Anatomical Position on the Compact Bone As Seen in Three Month Summer Ovine Model
… the compact-bone remodeling response to an ovariectomy model of human postmenopausal osteoporosis. Animal models are a beneficial practice allowing for the evaluation of the effectiveness of medical therapies and devices on diseases. The ovine model was chosen for this study due to its large …

The Use of Delayed Implantation Model in The Study of Hormonal Requirement for Implantation in The Rat
… rat model has been developed. Method of ovariectomy was described. Ovariectomy could be performed up to the morning of day 4, beyond that ovariectomy was not effective. Injection of Tamoxifen (10 or 50 (mu)g/200 g BW) in the afternoon of either day 4 or day 5 inhibited implantation. …

The Influence of Ovarian Sex Steroids on Insulin Receptor Status in Mice
… both skeletal muscle and liver. Neither 2 weeks ovariectomy nor the 2 week oral administration of oestradiol (5 ug/kg/day) to ovariectomised mice had any significant effect on the insulin binding capacity of hepatocytes in the presence of insulin concentrations ranging from 0 to 1000 ng/ml. The …

Ovarian and Growth Hormone Regulation of Mammary Growth and Transcript Abundance in Prepubertal Dairy Heifers
… first study, we determined the effect of staged ovariectomy on mammary growth and development in two to four month old Holstein heifers. In the second study, effects of bST on mammary growth and development, and also on putative stem cell population were evaluated by beginning bST treatment in …

Effect of Short-Term Estrogen Depletion on Compact Bone Microdensitometry in the Ewe
… does not undergo a natural menopause and an ovariectomy was necessary to replicate the condition. The study objective was to quantify compact bone density present in ovine at three months post ovariectomy.</p> <p>The study included 112 ovine separated into different treatment groups. The …

Effects of diet and loss of ovarian hormone production on adiposity, inflammation, cecal integrity, and gut microbial communities of rodent models
… OVX mice fed LFD. Compared to intact controls, ovariectomy led to greater (p<0.05) adipose and hepatic tissue inflammation, macrophage infiltration, oxidative stress, hindered insulin signaling and glucose uptake, and altered lipid and energy metabolism. Moreover, HFD feeding of OVX mice led to …

Growth Factor and Extracellular Matrix Regulation of Heifer Mammary Development
… and epithelial cell proliferation in response to ovariectomy coincided with decreased mammary expression of IGF-I mRNA and decreased binding of IGF-I to mammary microsomes. Taken together, these results imply an important role for locally derived IGF-I in regulating heifer mammary development. …

Effects of Fertility Control on the Movement Ecology of White-Tailed Deer
… fertility control methods, including vasectomy, ovariectomy, and immunocontraceptive vaccines, present alternative solutions that may circumvent the need for lethal management. However, these methods induce physiological changes that may alter movement behavior. This thesis aims to bridge the …

Estrogen Depletion Effects on Myelination and Lipid Regulation within the Central Nervous System
… this dissertation proposes the combination of ovariectomy surgery, the most common menopause model, with a demyelination model, the Plp1-iCKO-Myrf mouse model, to study the effects of estrogen depletion on myelin and myelination pathways. Chapter 2 outlines the generation and validation of this …

The Effects of Tamoxifen on Mammary Development in Prepubertal Heifers
… cell differentiation similar to what is seen in ovariectomy. We were able to effectively use a new technique of multispectral imaging to identify label retaining cells, which led to the discovery of an increase in the percentage of label retaining cells in TAM compared to CON. While treatment …

The role of boron alone or in combination with estrogen or PTH in the treatment of postmenopausal osteoporosis in ovariectomized rats
… week-old rats. Treatment began on day 43 after ovariectomy and continued for 5 weeks. Treatments included 5 ppm (5 mg per kg diet) boron as boric acid, 17β estradiol (30 μg/kg/d, s.c.), PTH (rat PTH 1-34 fragment, 60 μg/kg/d, s.c.), boron+17β estradiol, and boron+PTH at the same dose. All rats …
