Effect Of Kisspeptin On Regulation Of Growth Hormone, Brian K. Whitlock, Joseph A. Daniel, Robyn R. Wilborn, Herris S. Maxwell, Barbara P. Steele, James L. Sartin 2011 University of Tennessee - Knoxville

Effect Of Kisspeptin On Regulation Of Growth Hormone, Brian K. Whitlock, Joseph A. Daniel, Robyn R. Wilborn, Herris S. Maxwell, Barbara P. Steele, James L. Sartin

Brian K Whitlock, PhD, DVM, DACT

Kisspeptin ( KP ), a neuroendocrine regulator of reproduction, is hypothesized to be an integrator of metabolism and hormones critical to the regulation of reproduction. Lactation is associated with enhanced growth hormone (GH) responsiveness and reduced fertility. Our study was designed to determine the effects of lactation on KP-stimulated GH and luteinizing hormone (LH) secretion. Five non-lactating and five lactating dairy cows were used in the study. Experiments were conducted with lactating cows at weeks 1, 5 and 11 after parturition. The experimental treatments ( saline and KP [100 and 400 pmol / kg body weight]) were given intravenously and blood was collected and ...

Alpha-Defensins 1-3 Release By Dendritic Cells Is Reduced By Estrogen, Maria M. Escribese, Marta Rodríguez-García, Rhoda Sperling, Stephanie M. Engel 2011 Mount Sinai School of Medicine

Alpha-Defensins 1-3 Release By Dendritic Cells Is Reduced By Estrogen, Maria M. Escribese, Marta Rodríguez-García, Rhoda Sperling, Stephanie M. Engel

Dartmouth Scholarship

During pregnancy the immune system of the mother must protect any activation that may negatively affect the fetus. Changes in susceptibility to infection as well as resolution of some autoimmune disorders represent empirical evidence for pregnancy related alterations in immunity. Sex hormones reach extremely high levels during pregnancy and have been shown to have direct effects on many immune functions including the antiviral response of dendritic cells. Among the immunologically active proteins secreted by monocyte derived DCs (MDDC) are the alpha-defensins 1-3. This family of cationic antimicrobial peptides has a broad spectrum of microbicidal activity and has also been shown ...

Kisspeptin receptor (Kiss1r) agonists with increased half-life and similar efficacy to kisspeptin (KP) in vitro potentially may provide beneficial applications in breeding management of many species. However, many of these agonists have not been tested in vivo. This study was designed to test the effect of a Kiss1r agonist (FTM080) on luteinizing hormone (LH) in vivo. Sheep were treated with FTM080 (500 pmol/kg BW) or sterile water in a 2-ml bolus via the jugular cannula. Serial blood samples were collected every 15-min before (1 hr) and after (1 hr) treatment. Intravenous (IV) injection of FTM080 increased (P < 0.05) LH plasma concentrations through the 45-min sample following treatment. Moreover, the area under the curve of LH in the period from 0 to 60-min following FTM080 treatment was also increased (P < 0.05). These data provide evidence to suggest that FTM080 stimulates the gonadotropic axis of ruminants in vivo.


Effects Of Electroejaculation On Plasma Concentrations Of Cortisol And Substance P In Beef Bulls, Brian Whitlock, Elizabeth Coffman, Johann Coetzee, Joseph Daniel 2011 University of Tennessee - Knoxville

Effects Of Electroejaculation On Plasma Concentrations Of Cortisol And Substance P In Beef Bulls, Brian Whitlock, Elizabeth Coffman, Johann Coetzee, Joseph Daniel

Brian K Whitlock, PhD, DVM, DACT

Evaluating a semen sample is an integral part of the bull breeding soundness examination. Electroejaculation is a reliable method of obtaining a semen sample for the purpose of evaluating breeding soundness, but is considered by some to be inhumane on the grounds that it is painful. Numerous techniques have been used to evaluate pain associated with electroejaculation in animals and all have their strengths and weaknesses. Substance P is a neuropeptide involved in the integration of pain, stress, and anxiety. Measurement of plasma concentrations of substance P may enable discrimination between a stressful event culminating in an increase in plasma ...

Prevalence Of Premature Ovarian Failure In Women With Tuberous Sclerosis, Emily Gabitzsch 2011 University of Texas Graduate School of Biomedical Sciences at Houston

Prevalence Of Premature Ovarian Failure In Women With Tuberous Sclerosis, Emily Gabitzsch

The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences Dissertations and Theses (Open Access)

Tuberous Sclerosis Complex (TSC) is an autosomal dominant tumor suppressor disorder characterized by hamartomas, or benign growths, in various organ systems. Inactivating mutations in either the TSC1 or the TSC2 gene cause most cases of TSC. Recently, the use of ovarian specific conditional knock-out mouse models has demonstrated a crucial role of the TSC genes in ovarian function. Mice with complete deletion of Tsc1 or Tsc2 showed accelerated ovarian follicle activation and subsequent premature follicular depletion, consistent with the human condition premature ovarian failure (POF). POF is defined in women as the cessation of menses before the age of 40 ...

Type, Content, And Source Of Social Support Perceived By Women During Pregnancy: Evidence From Matlab, Bangladesh, Joyce K. Edmonds, Moni Paul, Lynn M. Sibley 2011 Emory University

Type, Content, And Source Of Social Support Perceived By Women During Pregnancy: Evidence From Matlab, Bangladesh, Joyce K. Edmonds, Moni Paul, Lynn M. Sibley

Joyce K. Edmonds

Specific and contextualized data on social support during distinct health events are needed to improve social support interventions. This study identified the type, content, and source of social support perceived by women during pregnancy. In-depth interviews with 25 women, aged 18-49 years, living in Matlab, Bangladesh, were conducted. The findings demonstrated that women perceived, the receipt of eight distinct types of support. The four most frequently-mentioned types included: practical help with routine activities, information/advice, emotional support and assurance, as well as the provision of resources and material goods. Sources varied by type of support and most frequently included--mothers, mothers-in-law ...

An increasing number of serodiscordant couples are utilizing advanced reproductive technologies to address their reproductive needs. Recent literature has demonstrated that it is not only technically possible but also safe to utilize sperm-washing techniques to allow for the creation of embryos, thereby preventing both horizontal and vertical transmission of HIV. This article addresses the strengths and weakness of various reproductive techniques and discusses our experience at Columbia University (NY, USA), the location of the largest HIV-focused fertility program in the USA.


Neural Regulation Of Feed Intake: Modification By Hormones, Fasting, And Disease, James Sartin, Brian Whitlock, Joseph Daniel 2010 Berry College

Neural Regulation Of Feed Intake: Modification By Hormones, Fasting, And Disease, James Sartin, Brian Whitlock, Joseph Daniel

Brian K Whitlock, PhD, DVM, DACT

Appetite is a complex process that results from the integration of multiple signals at the hypothalamus. The hypothalamus receives neural signals; hormonal signals such as leptin, cholecystokinin, and ghrelin; and nutrient signals such as glucose, FFA, AA, and VFA. This effect is processed by a specific sequence of neurotransmitters beginning with the arcuate nucleus and orexigenic cells containing neuropeptide Y or agouti-related protein and anorexigenic cells containing proopiomelanocortin (yielding the neurotransmitter α-melanocyte-stimulating hormone) or cells expressing cocaine amphetamine-related transcript. These socalled first-order neurons act on second-order orexigenic neurons (containing either melanin-concentrating hormone or orexin) or act on anorexigenic neurons (e ...

Immunocontraception In Wild Horses (Equus Caballus) Extends Reproductive Cycling Beyond The Normal Breeding Season, Cassandra M.V. Nuñez, James S. Adelman, Daniel I. Rubenstein

Cassandra M.V. Nuñez

Although the physiological effects of immunocontraceptive treatment with porcine zona pellucida (PZP) have been well studied, little is known about PZP's effects on the scheduling of reproductive cycling. Recent behavioral research has suggested that recipients of PZP extend the receptive breeding period into what is normally the non-breeding season. To determine if this is the case, we compiled foaling data from wild horses (Equus caballus) living on Shackleford Banks, North Carolina for 4 years pre- and 8 years post-contraception management with PZP (pre-contraception, n = 65 births from 45 mares; post-contraception, n = 97 births from 46 mares). Gestation lasts approximately ...

Appetite control is a major issue in normal growth and in suboptimal growth performance settings. A number of hormones, in particular leptin, activate or inhibit orexigenic or anorexigenic neurotransmitters within the arcuate nucleus of the hypothalamus, where feed intake regulation is integrated. Examples of appetite regulatory neurotransmitters are the stimulatory neurotransmitters neuropeptide Y (NPY), agouti-related protein (AgRP), orexin and melanin-concentrating hormone and the inhibitory neurotransmitter, melanocyte-stimulating hormone (MSH). Examination of messenger RNA (using in situ hybridization and realtime PCR) and proteins (using immunohistochemistry) for these neurotransmitters in ruminants has indicated that physiological regulation occurs in response to fasting for several ...
