Intra-articular steroids for the treatment of coxarthrosis; a retrospective cohort study comparing three contrast techniques.

Introduction: Intra-articular steroid injections (IAS) are a treatment for coxarthrosis. This study examines the efficacy of three fluoroscopy-guided IAS contrast techniques for coxarthrosis: contrast-assisted (Iohexol), air arthrogram-assisted and blind (contrast/air free) and stratifies efficacy based on multiple patient variables.

Materials And Methods: A cohort of 307 hip IAS was retrospectively analysed over a four-year period.

Effects of central and peripheral administration of an acute-phase protein, α-1-acid-glycoprotein, on feed intake and rectal temperature in sheep.

In rodents, an acute-phase protein, α-1-acid-glycoprotein (AGP), was shown to provide a link between inflammation and suppression of feed intake by acting as a leptin receptor agonist. The objective of this study was to determine the effects of AGP on feed intake and rectal temperature in sheep. Ewes were ovariectomized, implanted with a cannula into a lateral ventricle of the brain, and kept indoors in individual pens.

Factors associated with seroprevalence of bovine anaplasmosis in Mississippi, USA.

Anecdotally, Veterinary Feed Directive prescriptions in the southeastern United States (U.S.) are written most often for treatment and prevention of bovine anaplasmosis (BA) but seroprevalence estimates and factors associated with this disease are currently unavailable in Mississippi (MS).

Factors associated with Seroprevalence of Anaplasma marginale in Kentucky cattle.

Bovine anaplasmosis (BA) is tick-borne disease of cattle caused by Anaplasma marginale and it remains an economically important disease in the United States (U.S.).

Factors associated with seroprevalence of bovine anaplasmosis in Texas.

Bovine anaplasmosis (BA), caused by Anaplasma marginale, is an economically important tick-borne disease of cattle in the United States (U.S.) and worldwide.

Seroprevalence of bovine Anaplasmosis in Georgia.

Anecdotally, Veterinary Feed Directive prescriptions in many states in the southeastern United States (U.S.) are written most often for treatment and prevention of bovine anaplasmosis (BA).

Kisspeptin receptor agonist (FTM080) increased plasma concentrations of luteinizing hormone in anestrous ewes.

Kisspeptin receptor (KISS1R) agonists with increased half-life and similar efficacy to kisspeptin in vitro may provide beneficial applications in breeding management of many species. However, many of these agonists have not been tested in vivo. These studies were designed to test and compare the effects of a KISS1R agonist (FTM080) and kisspeptin on luteinizing hormone (LH) in vivo.

Reproduction and beyond, kisspeptin in ruminants.

Kisspeptin (Kp) is synthesized in the arcuate nucleus and preoptic area of the hypothalamus and is a regulator of gonadotropin releasing hormone in the hypothalamus. In addition, Kp may regulate additional functions such as increased neuropeptide Y gene expression and reduced proopiomelanocortin (POMC) gene expression in sheep. Other studies have found a role for Kp to release growth hormone (GH), prolactin and luteinizing hormone (LH) from cattle, rat and monkey pituitary cells.

Interaction of estrogen and progesterone on kisspeptin-10-stimulated luteinizing hormone and growth hormone in ovariectomized cows.

Background/aims: Growth hormone (GH) is necessary for optimal reproductive efficiency and its secretion is influenced by sex steroids. This study was designed to determine whether kisspeptin-10 (Kp10) could stimulate GH and if gonadal steroids enhance the GH response to Kp10 in cows.

Methods And Results: Intravenous injection of Kp10 at 100 or 200 pmol/kg body weight with or without treatment with estradiol cypionate and/or progesterone increased luteinizing hormone (p < 0.

Evaluation of the prevalence and onset of lung lesions and their impact on growth of lambs.

Objective: To determine the prevalence and temporal onset of lung lesions in lambs and the impact of lung lesions on growth of affected lambs.

Animals: 259 crossbred wether lambs from a single flock in the upper Midwestern United States.

Procedure: An observational study was conducted.

A role for agouti-related protein in appetite regulation in a species with continuous nutrient delivery.

Knowledge of specific neurotransmitters as well as the pathways and mechanisms regulating appetite in ruminants that continually graze, such as sheep, is incomplete. Although fundamentally agouti-related protein (AGRP) has a similar function across species to increase food intake, the regulation of AGRP may vary across grazing and intermittent feeders. To investigate the role of orexigenic peptides in the regulation of feed intake, we first extracted messenger RNA from sheep that were fasted for 3 days, which was then used for PCR followed by cloning and sequencing to demonstrate the presence of hypothalamic AGRP expression.
