Resistant Hypertension: Risk Factors, Subclinical Atherosclerosis, And Comorbidities Among Adults—The Brazilian Longitudinal Study Of Adult Health (Elsa-Brasil), Paulo A. Lotufo

Paulo A Lotufo

The frequency of resistant hypertension—defined as blood

pressure (BP) ≥140/90 mm Hg with proven use of three

antihypertensive medications, or as the use of four antihypertensive drug classes regardless of BP—is unknown in low-middle–income countries. Using data from the Brazilian Longitudinal Study of Adult Health, a cohort of 15,105 civil servants aged 35 to 74 years, the authors identified 4116 patients taking treatment for hypertension, 11% of who had resistant hypertension. These participants were more likely to be older, black, less educated, poorer, and obese. The adjusted prevalence ratios (95% confidence intervals) were diabetes, 1.44 (1.20–1.72); glomerular filtration rate ( …

Tissue Distribution And Thyroid Hormone Effects On Mrna Abundance For Membrane Transporters Mct8, Mct10, And Organic Anion-Transporting Polypeptides (Oatps) In A Teleost Fish, Amanda M. Muzzio, Pamela D. Noyes, Heather M. Stapleton, Sean C. Lema

Sean Lema

Many of the actions of thyroid hormones (THs) occur via TH binding to intracellular receptors. Although it was long thought that THs diffused passively across plasma membranes, it is now recognized that cellular entry is mediated by a variety of membrane transporter proteins. In this study, we identified cDNAs encoding the TH transporters monocarboxylate transferases 8 (mct8) and 10 (mct10) as well as eight distinct organic anion-transporting polypeptide (oatp) proteins from fathead minnow (Pimephales promelas). Analysis of the tissue distribution of transporter mRNAs revealed that mct8 and mct10 transcripts were both abundant in liver, but also present at lower levels …

Kisspeptin Receptor Agonist (Ftm080) Increased Plasma Concentrations Of Luteinizing Hormone In Anestrous Ewes, Brian K. Whitlock, Kelly A. Chameroy, Rebecca R. Payton, Shinya Oishi, Nobutaka Fujii, Joseph A. Daniel

Brian K Whitlock, PhD, DVM, DACT

Kisspeptin (KP) and the KP receptor (Kiss1r) are integral to central regulation of the gonadotropic-axis. The demonstration that intravenous infusion of KP can stimulate gonadotropin secretion and ovulation in seasonally anestrous female sheep offers a means of manipulating the reproductive axis. However, KP may be of limited clinical use because of the short circulating half-life. Kiss1r agonists with increased half-life and similar efficacy to 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 and compare the effects of …

Effect Of Meloxicam On Gain And Inflammatory Response Of Calves Castrated By Banding Post-Weaning, Brian K. Whitlock, Peter D. Krawczel, Jeff A. Carroll, Nicole C. Burdick Sanchez, Jeff W. Dailey, Joseph A. Daniel, Johann F. Coetzee

Brian K Whitlock, PhD, DVM, DACT

Castration may detrimentally affect the health and performance of weaned calves, and painful procedures are increasingly becoming a public concern. The objective of this study was to determine the effects of castration (by banding) with or without administration of meloxicam, a non-steroid anti-inflammatory, on performance and inflammatory response in weaned beef calves. Forty-eight (weaned) beef calves [10.0±0.2 mo old; 304±6 kg BW] were blocked by age, BW, wither height, scrotal circumference, and source, then randomly assigned to 1 of 3 treatments (n=16 calves per treatment: 1) intact bulls (BULL), 2) castration by banding (BAN), or 3) castration by banding with …

The objective was to determine if oral meloxicam (M; a non-steroid anti-inflammatory) administered at castration of pre-weaning calves affected ADG or behavior. Prior to castration (14 d), Angus bulls were assigned to bull (BULL; n = 7; age 106 ± 6 d; BW = 174.2 ±7.7 kg; scrotal circumference 17.7 ± 0.4 cm), castrated (BAN; n = 12; age = 105 ± 5 d; BW = 144.5 ± 7.6 kg; scrotal circumference = 16 ± 0.4 cm) or castrated with meloxicam (BAN+M; n = 13; age = 121 ± 6 d; BW = 145.8 ± 6 kg; scrotal circumference = …

Divergence In Thyroid Hormone Concentrations Between Juveniles Of Marine And Stream Ecotypes Of The Threespine Stickleback (Gasterosteus Aculeatus), Jun Kitano, Sean C. Lema

Sean Lema

Background: Hormones regulate the expression of multiple phenotypic traits. Therefore,

divergence in hormone concentrations may lead to evolutionary changes in the coordinated

physiological and behavioural traits that comprise an organism’s integrated phenotype. Adults

of marine ecotypes of threespine stickleback (Gasterosteus aculeatus) have higher concentrations

of the thyroid hormone thyroxine (T4) than adults of stream-resident ecotypes (Kitano

et al., 2010). Thyroid hormones are well-established mediators of osmoregulation and migratory

behaviours in fish, and the difference in T4 concentrations indicates that changes in thyroid

hormone signalling may underlie the evolutionary and ecological divergence of migratory and

non-migratory ecotypes.

Questions: Is the variation …

Hormones And Phenotypic Plasticity: Implications For The Evolution Of Integrated Adaptive Phenotypes, Sean C. Lema, Jun Kitano

Sean Lema

It is generally accepted that taxa exhibit genetic variation in phenotypic plasticity, but many questions remain unanswered about how divergent plastic responses evolve under dissimilar ecological conditions. Hormones are signaling molecules that act as proximate mediators of phenotype expression by regulating a variety of cellular, physiological, and behavioral responses. Hormones not only change cellular and physiological states but also influence gene expression directly or indirectly, thereby linking environmental conditions to phenotypic development. Studying how hormonal pathways respond to environmental variation and how those responses differ between individuals, populations, and species can expand our understanding of the evolution of phenotypic plasticity. …

Cosmic Ray Particles Images With Orca-Ii Erg, George Mcnamara

George McNamara

Cosmic ray particles image series acquired using a Hamamatsu ORCA-II ERG scientific grade CCD camera, cooled to -60 C. Each image is a consecutive 600 second (10 minute) exposure time with no light to the camera.

While processing the data, I discoverd that the background changed around planes 25 and 227 (see Excel file and jpeg screenshots), so I also processed only planes 025-227 (203 planes total, 2030 minutes, 33.83 hours). the CCD industry "rule of thumb" for a "typical" CCD sensor (i.e. 1/3" CCD) is that one cosmic ray particle strikes a sensor approximately every 30 seconds (assuming not …

Propiconazole Is A Specific And Accessible Brassinosteroid (Br) Biosynthesis Inhibitor For Arabidopsis And Maize., Burkhard Schulz, Thomas Hartwig, Claudia Corvalan, Norman Best, Joshua Budka, Sunghwa Choe

Burkhard Schulz

Brassinosteroids (BRs) are steroidal hormones that play pivotal roles during plant development. In addition to the characterization of BR deficient mutants, specific BR biosynthesis inhibitors played an essential role in the elucidation of BR function in plants. However, high costs and limited availability of common BR biosynthetic inhibitors constrain their key advantage as a species-independent tool to investigate BR function. We studied propiconazole (Pcz) as an alternative to the BR inhibitor brassinazole (Brz). Arabidopsis seedlings treated with Pcz phenocopied BR biosynthetic mutants. The steady state mRNA levels of BR, but not gibberellic acid (GA), regulated genes increased proportional to the …

Variation In Gene Transcript Profiles Of Two V1a-Type Arginine Vasotocin Receptors Among Sexual Phases Of Bluehead Wrasse (Thalassoma Bifasciatum), Sean C. Lema, Melissa A. Slane, Kelley E. Salvesen, John Godwin

Sean Lema

The neurohypophyseal hormone arginine vasotocin (AVT) mediates behavioral and reproductive plasticity in vertebrates, and has been linked to the behavioral changes associated with protogyny in the bluehead wrasse (Thalassoma bifasciatum). In this study, we sequenced full-length cDNAs encoding two distinct V1a-type AVT receptors (v1a1 and v1a2) from the bluehead wrasse, and examined variation in brain and gonadal abundance of these receptor transcripts among sexual phases. End point RT-PCR revealed that v1a1 and v1a2 transcripts varied in tissue distribution, with v1a1 receptor mRNAs at greatest levels in the telencephalon, hypothalamus, optic tectum, cerebellum and testis, and v1a2 receptor transcripts most abundant …

Heifer Estrous Cycle Stage Impacts Luteinizing And Growth Hormone Response To Kisspeptin, Brian K. Whitlock, Joseph A. Daniel, Robyn R. Wilborn, Barbara P. Steele, James L. Sartin

Brian K Whitlock, PhD, DVM, DACT

The reproductive neuropeptide, kisspeptin (KP), may have a role in regulation of growth hormone (GH) secretion. Expression of KP and its receptor (Kiss1r) are developmentally and hormonally regulated. This study was conducted to determine the effects of KP on plasma concentrations of luteinizing hormone (LH) and GH in pubertal heifers during different functional reproductive stages. Heifers received a single injection of KP (100 pmole / kg) or saline intravenously during proestrus, estrus, and diestrus, and serial blood samples were collected for 3 hours to determine the response of both LH and GH after treatment. Mean concentrations of LH were increased …

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 …
