Orthostatic-Induced Hypotension Attenuates Cold Pressor Pain Perception, Karen Y. Wonders, Daniel G. Drury

Health Sciences Faculty Publications

In recent years, numerous studies have established a connection between blood pressure and nocioception. While this connection is well documented in the literature, its underlying physiological mechanisms have yet to be elucidated. Much attention has focused on the relationship between cardiovascular regulatory centers and nocioception, yet the intricacies of this relationship have not been fully explored. Therefore, the purpose of this investigation was to examine the role of the baroreflex system as a modulator of pain perception. Twenty normotensive males participated in two laboratory sessions. Time to cold pain threshold and pain tolerance was measured at rest during the first …

Very-Long-Chain Fatty Acids Are Involved In Polar Auxin Transport And Developmental Patterning In Arabidopsis, Françoise Roudier, Lionel Gissot, Frédéric Beaudoin, Richard Haslam, Louise V. Michaelson, Jessica Marion, Diana Molino, Amparo Lima, Liên Bach, Halima Morin, Frédérique Tellier, Jean-Christophe Palauqui, Yannick Bellec, Charlotte Renne, Martine Miquel, Marco Dacosta, Julien Vignard, Christine Rochat, Jennifer E. Markham, Patrick Moreau, Jonathan Napier, Jean-Denis Faure

Department of Biochemistry: Faculty Publications

Very-long-chain fatty acids (VLCFAs) are essential for many aspects of plant development and necessary for the synthesis of seed storage triacylglycerols, epicuticular waxes, and sphingolipids. Identification of the acetyl-CoA carboxylase PASTICCINO3 and the 3-hydroxy acyl-CoA dehydratase PASTICCINO2 revealed that VLCFAs are important for cell proliferation and tissue patterning. Here, we show that the immunophilin PASTICCINO1 (PAS1) is also required for VLCFA synthesis. Impairment of PAS1 function results in reduction of VLCFA levels that particularly affects the composition of sphingolipids, known to be important for cell polarity in animals. Moreover, PAS1 associates with several enzymes of …

The Effect Of Water Depth On Energy Expenditure And Perception Of Effort In Female Subjects While Walking, Wafa Alkurdi, David R. Paul, Kelsey Sadowski, Dennis G. Dolny

International Journal of Aquatic Research and Education

The purpose of this study was to compare energy expenditure (EE), heart rate, and perceived effort during walking in water at several depths versus land in female participants. Eighteen females walked on three separate days on a land treadmill (Land) and in a water treadmill (ATM) at 30° C at 6 speeds. Water depth was at the xiphoid (xip), 10 cm below (-10 cm), and 10 cm above xip (+10 cm). Heart rate (HR), oxygen consumption (VO2) and carbon dioxide production (VCO2) were recorded. RPE overall (RPE-O) and RPE legs (RPE-L) were solicited following each bout. Regardless of walking speed, …

Laboratory Evaluation Of Novaluron As A Rodent Feed-Through Insecticide Against Sand Fly Larvae (Diptera: Psychodidae), T. M. Mascari, L. D. Foil

Faculty Publications

Experiments were conducted to evaluate novaluron as a feed-through larvicide to control immature phlebotomine sand flies (Phlebotomus papatasi Scopoli) (Diptera: Psychodidae). The minimum effective concentration of novaluron against sand fly larvae fed hamster feces treated with novaluron, or feces of hamsters fed a diet containing novaluron, was 9.88 and 9.88 × 10-1 mg/kg, respectively. Feces of novaluron-treated hamsters were held under conditions simulating the inside of a rodent burrow for up to 30 d, and all larvae that consumed these feces died before pupation; a significant reduction in treated larval survival relative to control was observed when the feces were …

Central Nervous System Depressant Properties Of Treculia Africana Decne, A. O. Aderibigbe, I. O. Adeyemi, O. I. Agboola

Ethnobotanical Leaflets

The study was carried out to investigate the central nervous system activity of Treculia africana. The central nervous system depressant properties of Treculia africana were determined using: Novelty –Induced Rearing and Grooming, Locomotor activity, Ketamine-induced sleeping time and effect on rectal body temperature. The crude extract produced decrease in rearing, grooming and locomotor activity. It also potentiated ketamineinduced sleeping time and produced hypothermic effect in mice. The crude extract possessed sedative effect, which may be through increase in the activity of GABA in the brain.

Intracellular Consequences Of Sos1 Deficiency During Salt Stress, Dong Ha Oh, Sang Yeol Lee, Ray A. Bressan, Dae Jin Yun, Hans J. Bohnert

Faculty Publications

A mutation of AtSOS1 (Salt Overly Sensitive 1), a plasma membrane Na +/H+-antiporter in Arabidopsis thaliana, leads to a salt-sensitive phenotype accompanied by the death of root cells under salt stress. Intracellular events and changes in gene expression were compared during a non-lethal salt stress between the wild type and a representative SOS1 mutant, atsos1-1, by confocal microscopy using ion-specific fluorophores and by quantitative RT-PCR. In addition to the higher accumulation of sodium ions, atsos1-1 showed inhibition of endocytosis, abnormalities in vacuolar shape and function, and changes in intracellular pH compared to the wild type in root tip cells under …

Genome Sequence Of The Pea Aphid Acyrthosiphon Pisum, International Aphid Genomics Consortium, Gregory K. Davis

Biology Faculty Research and Scholarship

Aphids are important agricultural pests and also biological models for studies of insect-plant interactions, symbiosis, virus vectoring, and the developmental causes of extreme phenotypic plasticity. Here we present the 464 Mb draft genome assembly of the pea aphid Acyrthosiphon pisum. This first published whole genome sequence of a basal hemimetabolous insect provides an outgroup to the multiple published genomes of holometabolous insects. Pea aphids are host-plant specialists, they can reproduce both sexually and asexually, and they have coevolved with an obligate bacterial symbiont. Here we highlight findings from whole genome analysis that may be related to these unusual biological …

Ecological Niche And Potential Geographic Distribution Of The Invasive Fruit Fly Bactrocera Invadens (Diptera, Tephritidae), M. De Meyer, M. P. Robertson, M. W. Mansell, S. Ekesi, K. Tsuruta, W. Mwaiko, J. F. Vayssières, A. T. Peterson

All Peer-Reviewed Publications

Two correlative approaches to the challenge of ecological niche modeling (genetic algorithm, maximum entropy) were used to estimate the potential global distribution of the invasive fruit fly, Bactrocera invadens, based on associations between known occurrence records and a set of environmental predictor variables. The two models yielded similar estimates, largely corresponding to Equatorial climate classes with high levels of precipitation. The maximum entropy approach was somewhat more conservative in its evaluation of suitability, depending on thresholds for presence/absence that are selected, largely excluding areas with distinct dry seasons; the genetic algorithm models, in contrast, indicate that climate class as partly …

Chlamydomonas Mutants Display Reversible Deficiencies In Flagellar Beating And Axonemal Assembly, Mei Wei, Priyanka Sivadas, Heather A. Owen, David R. Mitchell, Pinfen Yang

Biological Sciences Faculty Research and Publications

Axonemal complexes in flagella are largely prepackaged in the cell body. As such, one mutation often results in the absence of the co-assembled components and permanent motility deficiencies. For example, a Chlamydomonas mutant defective in RSP4 in the radial spoke (RS), which is critical for bend propagation, has paralyzed flagella that also lack the paralogue RSP6 and three additional RS proteins. Intriguingly, recent studies showed that several mutant strains contain a mixed population of swimmers and paralyzed cells despite their identical genetic background. Here we report a cause underlying these variations. Two new mutants lacking RSP6 swim processively and other …

Spectrophotometric And Colorimetic Methodology To Detect And Quantify Hydrazide Based Chemotherapeutic Drugs, Ronald Bartzatt

An Integrated Intervention To Reduce Intimate Partner Violence In Pregnancy: A Randomized Trial, Michele Kiely, Ayman El-Mohandes, M. Nabil El-Khorazaty, Marie G. Gantz

Publications and Research

OBJECTIVE: We estimated the efficacy of a psycho-behavioral intervention in reducing intimate partner violence (IPV) recurrence during pregnancy and postpartum, and in improving birth outcomes in African-American women

METHODS: We conducted a randomized controlled trial in which 1,044 women were recruited. Individually-tailored counseling sessions were adapted from evidence-based interventions for IPV and other risks. Logistic regression was used to model IPV victimization recurrence, to predict minor, severe, physical and sexual IPV.

RESULTS: Women randomized to the intervention were less likely to have recurrent episodes of IPV victimization (OR=0.48, 95%CI=0.29-0.80). Women with minor IPV were significantly less likely to experience further …

A Lanthanide-Based Chemosensor For Bioavailable Fe3+ Using A Fluorescent Siderophore: An Assay Displacement Approach, Karen M. Orcutt, William Scott Jones, Andrea Mcdonald, David Schrock, Karl J. Wallace

Faculty Publications

The measurement of trace analytes in aqueous systems has become increasingly important for understanding ocean primary productivity. In oceanography, iron (Fe) is a key element in regulating ocean productivity, microplankton assemblages and has been identified as a causative element in the development of some harmful algal blooms. The chemosenor developed in this study is based on an indicator displacement approach that utilizes time-resolved fluorescence and fluorescence resonance energy transfer as the sensing mechanism to achieve detection of Fe3+ ions as low as 5 nM. This novel approach holds promise for the development of photoactive chemosensors for ocean deployment.

The Economics Of Climate Enforcement, Omri Ben-Shahar, Anu Bradford

Coase-Sandor Institute for Law & Economics Research Paper Series

Any breakthrough in international climate change negotiations has to address the enforcement problem: how to entice reluctant states to meet the emission reduction targets set by treaties. The challenge is acute because traditional enforcement measures—sanctions or rewards—are insufficient. The threat to impose sanctions on violator states is too costly and hence not credible; and the magnitude of rewards violators demand for their compliance is excessive. This article proposes a novel enforcement mechanism, which combines sanctions and rewards in a way that is both credible and cheaper than existing proposals. The idea is to set up a reward fund that serves …

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Three subfamilies of grasses, the Ehrhartoideae, Panicoideae and Pooideae, provide the bulk of human nutrition and are poised to become major sources of renewable energy. Here we describe the genome sequence of the wild grass Brachypodium distachyon (Brachypodium), which is, to our knowledge, the first member of the Pooideae subfamily to be sequenced. Comparison of the Brachypodium, rice and sorghum genomes shows a precise history of genome evolution across a broad diversity of the grasses, and establishes a template for analysis of the large genomes of economically important pooid grasses such as wheat. The high-quality genome sequence, coupled …

Sky-Field: A Vertical Farming Solution For Urban New York, Justin White

Architecture Theses and Projects

Farming has not changed significantly in thousands of years. We still go about blanketing the ground with acres and acres of crops far away from the people who eat it. “We now have to talk and bring the green movement into our food supply. We will find a place in NY to do this,” states Scott Stringer, Manhattan Borough President. The concept is to design a vertical farm tower which will feed thousands of local residents, allowing them cheaper, organic, disease-free crops. The supply structure of the agricultural industry needs a big change. It is no longer becoming economical due …
