The effect of Zoledronate treatment timing on lumbar and caudal vertebrae in ovariectomized rats
… lumbar and caudal vertebrae in ovariectomized [OVX], female Wistar rats. Methods: Twenty nine rats were divided into four groups according to their treatment: OVX at week 0 (n=5), OVX+earlyZOL (20 jig/kg s.c. week 0, n=8), OVX+late ZOL (20 jlg/kg s.c. week 8, n=7), and SHAM-OVX (n=9). Results: …

Can low-dose lithium supplementation protect against sarcopenic obesity in ovariectomized mice?
… against sarcopenic obesity in ovariectomized (OVX) mice. 28-week-old sham and OVX C57BL/6J mice were divided into a control (con) or Li group, giving rise to four groups: sham-con, OVX-con, sham-Li, and OVX-Li (n = 6-10 per group). OVX-Li mice were provided a dose of 50 mg/kg/day of Li via …

The Role of The Thyroid Gland in Regulating Synthesis and Release of Luteinizing Hormone in The Rat
… anterior pituitary gland (AP) of ovariectomized (Ovx) rats were investigated. Immediately after ovariectomy, rats were thyroidectomized (Tx) or sham-Tx. Starting thirty days later they were injected with saline or T(,4) for 9 days. On the thirty-ninth day, the APs were incubated in vitro with 3.6 …

Effects of diet and loss of ovarian hormone production on adiposity, inflammation, cecal integrity, and gut microbial communities of rodent models
… and the cecal microbiota in ovariectomized (OVX) rats bred for low-running capacity (LCR), a model that has been previously shown to mimic human menopause. Forty 27-wk old LCR rats were either OVX or sham-operated (SHM) and fed either soy-rich (soy) or soy-free (control) diets for 28 wk. Soy …

Effects of exercise and phytoestrogens on white adipose tissue health in estrogen deficient rodents
… diabetes, and many types of cancer. Ovariectomy (OVX) in rodents, a model of human menopause, is associated with reduced energy expenditure (EE), IR, weight gain primarily via increased adiposity, and WAT inflammation. Exercise and dietary phytoestrogen interventions can improve metabolic and WAT …

Examination of voluntary wheel running on markers of adipose thermogenesis in intact and ovariectomized female mice
… voluntary wheel running (VWR) in ovariectomized (OVX) mice on whole body energy expenditure and body composition, key protein markers of thermogenesis and adipose tissue browning, and fluctuations in circulating and AT BDNF and receptor content. It was hypothesized VWR would either prevent or …

The Effects of Estrogen Receptor -Alpha, Estrogen and Phytoestrogen on Global Myocardial Ischemia -Reperfusion Injury
… and fed a diet containing no phytoestrogen (OVX group). One group was ovariectomized, fed a phytoestrogen-free diet and was implanted a 17 beta-estradiol capsule subcutaneously (OVX+E2 group). One group was ovariectomized and fed a diet containing 49.39 mg isoflavones/g protein (HPE group). …

Einfluss der vertikalen Ganzkörpervibration unterschiedlicher Frequenz auf den osteoporotischen Lendenwirbelkörper der Ratte
… (SHAM) und eine ovariektomierte Kontrollgruppe (OVX), welche nicht vibriert wurden, zum anderen vier Gruppen ovariektomierter Tiere, welche mit den Frequenzen 35, 50, 70 und 90 Hz vibriert wurden (OVX 35 Hz, OVX 50 Hz, OVX 70 Hz und OVX 90 Hz). Über einen Zeitraum von 30 Tagen wurden die Tiere …

Investigating the role of estrogen deprivation and diet-induced insulin resistance on markers of amyloid-β production and degradation in the brain
… ovariectomy, to simulate estrogen loss, (OVX; n=20) or remained intact (n=20) at 24 weeks of age. Mice were then placed on either a low or high fat diet (LFD; n=10 for OVX and intact, HFD; n=10 for OVX and intact) for 10 weeks to induce insulin intolerance. Prefrontal cortex and …

A Study of the in Vivo Release of Luteinizing Hormone-Releasing Hormone as Estimated With the Push-Pull Perfusion Technique
… perfusion (PPP) system. Ovariectomized (OVx) rats received 5 (mu)g estradiol benzoate at 1000 h, followed 48 h later by 1.5mg progesterone (P) or oil. Rats in which P was administered showed a significant (p < 0.01) 40-min elevation of LHRH secretion at approximately 6 h following P. …

The action of ovarian steroids on the hypothalamic LHRH pulse generator
… release from ovariectomized-estrogen primed (OVX + E$\sb2$) rats. The present study reveals that the rat pituitary receives LHRH in larger quanta but at a fixed frequency (about 1 pulse/h) during proestrus than other cycling phases of the estrous cycle. Surprisingly, removal of ovarian …

The neuroendocrine mechanism of reproductive photorefractoriness in the ewe
… Ovary-intact (INTACT), ovariectomized (OVX) and ovariectomized estradiol-treated (OVX + E$\sb2$) ewes were subjected to 3 different photoperiodic regimens which resulted in reproductive quiescent: (1) exposure to long days (16L:8D), which caused photosuppression (LDPS); (2) prolonged …

Effects of Estrogen Loss on the Vascular Porosity in Rat Cortical Bone
… in the tibia metaphysis of ovariectomized (OVX) rats (Larriera et al., 2010). The present study investigated whether osteoclast resorption is responsible for the increased canal diameter, and if changes in the cortical blood vessel morphology occur due to estrogen loss. Alterations in the …

Porcine intrauterine steroidogenesis: luteal vs. intrauterine progesterone as a mediator of prenatal survival, conceptus development and in vitro steroid production by the placenta and endometrium
… in the pregnant gilt. In chapter 3, ovariectomy (OVX) and medroxyprogesterone acetate (MPA) treatment at two stages of gestation (d19-29 or d59-69) resulted in maintained pregnancy, normal fetal survival rates, normal conceptus development, and typical plasma estrogens when compared to intact, …

Bone Regeneration Potential of Mesenchymal Stromal Cells derived from a Clinically Relevant Rat Model of Osteoporosis
… most common animal model of OP is ovariectomy (OVX) that simulates post-menopausal estrogen loss. A plethora of bone regeneration studies have used OVX models with 12-16 weeks post-OVX periods and have generally reported positive results from a variety of treatment modalities, including MSC …

Gingival MSCs Improve Bone Phenotype in Ovariectomy-Induced Osteoporosis via Programmed Cell Death Pathway
… the bone mass reduction caused by Ovariectomy (OVX)-induced osteoporosis in both the femurs and mandibles of OVX mice, they also successfully rescued the function of the defective endogenous population of Bone Marrow Mesenchymal Stem Cells (BMMSCs). We saw that the systemic infusion of GMSCs …

The Effect of Lycii Radicis Cortex Extract on Bone Formation in vitro and in vivo
… extract in vivo was examined in ovariectomized (OVX) mice. The OVX mice administered LRC extract for 8 weeks and 16 weeks, respectively, exhibited significantly increased bone mineral density (BMD) compared to the non-treated control OVX mice, and no toxic effects were observed. My results …

Ovarian hormones, but not androgens, mediate running-induced changes in high fat diet choice patterns in rats
… females reverse HF diet avoidance. Ovariectomy (OVX) appears to decrease HF diet preference, bringing it closer to what is observed in male rats. Given that estrogen, but not progesterone, mediates changes in food intake and energy balance, we hypothesized that estrogen signaling is required for …

Intrauterine position in pigs: effects on conceptus development and fetal fluids steroid content
… (mOF). Fetuses examined from ovariectomized (OVX) pregnenolone (PS)-treated gilts showed differences in placental weight, allantoic fluid estrone and androstenedione content and amniotic fluid androstenedione content as a result of intrauterine position. Fetuses from OVX gilts treated with …
