Agonistic Behaviour And Biogenic Amines In Shore Crabs Carcinus Maenas, Lynne U. Sneddon, Alan C. Taylor, Felicity A. Huntingford, David G. Watson

Sentience Collection

To investigate the role of certain neurohormones in agonistic behaviour, fights were staged between pairs of size-matched male shore crabs Carcinus maenas, and blood samples were taken immediately after the contests had been resolved. Samples were also taken from these crabs at rest (before and after fighting) and after walking on a treadmill. A control group of crabs also had samples taken on each experimental day. Concentrations of tyramine, dopamine, octopamine, serotonin (5-HT) and norepinephrine were determined in each blood sample using a gas chromatography/mass spectrometry (GC-MS) system. Norepinephrine was not detectable in any of the samples, but the standards …

Impact Of Bovine Oocyte Maturation Media On Oocyte Transcript Levels, Blastocyst Development, Cell Number, And Apoptosis., A J Watson, P De Sousa, A Caveney, L C Barcroft, D Natale, J Urquhart, M E Westhusin

Obstetrics & Gynaecology Publications

The objectives were 1) to investigate the effects of oocyte maturation in serum-free and amino acid-supplemented defined media on oocyte transcript levels, blastocyst cell number, and apoptosis; 2) to investigate the influence of oocyte maturation culture atmosphere on blastocyst development, total cell number, and apoptosis; and 3) to examine the influence of epidermal growth factor (EGF) during oocyte maturation on blastocyst cell number and apoptosis. The results demonstrate that blastocysts derived from in vitro maturation, fertilization, and embryo culture protocols undergo apoptosis but that apoptotic levels are not greatly influenced by the oocyte maturation environment. Amino acid supplementation of oocyte …

The Differential Relations Of Parent And Peer Attachment To Adolescent Adjustment, Deborah J. Laible, Gustavo Carlo, Marcela Raffaelli

Department of Psychology: Faculty Publications

Whether or not close emotional relationships with parents and peers serve similar functions for adolescent adjustment is an issue of increasing interest. The present study was designed to examine the relations between parent and peer attachment and adolescent adjustment. Eighty-nine adolescents (M age = 16.1 years, SD = 1.8 years) completed self-report measures of parent and peer attachment, sympathy, academic efficacy, aggression, anxiety, and depression. Adolescents were divided into four groups on the basis of their parent and peer attachment scores: those high on both, those low on both, those high on peer but low on parent attachment, and those …

Integronlike Structures In Campylobacter Spp. Of Human And Animal Origin, Brigid Lucey, D. Crowley, P. Moloney, B. Cryan, M. Daly, F. O'Halloran, E. J. Threlfall, S. Fanning

Department of Biological Sciences Publications

Resistance to antimicrobial agents used to treat severe Campylobacter spp. gastroenteritis is increasing worldwide. We assessed the antimicrobial resistance patterns of Campylobacter spp. isolates of human and animal origin. More than half (n = 32) were resistant to sulphonamide, a feature known to be associated with the presence of integrons. Analysis of these integrons will further our understanding of Campylobacter spp. epidemiology.

Naturally Occurring Tap-Dependent Specific T-Cell Tolerance For A Variant Of An Immunodominant Retroviral Cytotoxic T-Lymphocyte Epitope, Victor Kim, Jonathan W. Yewdell, William R. Green

Dartmouth Scholarship

Upon immunization and restimulation with tumors induced by the endogenous AKR/Gross murine leukemia virus (MuLV), C57BL/6 mice generate vigorous H-2K(b)-restricted cytotoxic T-lymphocyte (CTL) responses to a determinant (KSPWFTTL) derived from the p15E transmembrane portion of the viral envelope glycoprotein. By contrast, the highly homologous determinant RSPWFTTL, expressed by tumor cells induced by Friend/Moloney/Rauscher (FMR) MuLV, is not immunogenic, even when presented to the immune system as vaccinia virus-encoded cytosolic or endoplasmic reticulum (ER)-targeted minigene products. Such minigene products are usually highly immunogenic since they bypass the need for cells to liberate the peptide or transport the peptide into the ER …

Conditioned Place Preference: What Does It Add To Our Preclinical Understanding Of Drug Reward?, M. T. Bardo, Rick A. Bevins

Department of Psychology: Faculty Publications

Rationale: Among the various experimental protocols that have been used to measure drug reward in laboratory animals, conditioned place preference (CPP) has been one of the most popular. However, a number of controversial issues have surrounded the use of this experimental protocol.
Objective: The present review provides a theoretical overview of some critical issues relevant to CPP. The advantages and limitations of CPP are also covered.
Results: Based on modern and traditional theoretical formulations of Pavlovian conditioning, CPP appears to reflect a preference for a context due to the contiguous association between the context and a drug stimulus. Within this …

Reshaping Ahcs' Role In Biomedical Research, Karen Matherlee

National Health Policy Forum

This issue brief explores the reconfiguration of academic health centers (AHCs) in response to health marketplace and other pressures. It reviews four roles AHCs play in medical innovation: (a) development of new drugs, devices, diagnostic techniques, and therapeutic procedures; (b) adoption of new technologies, instruments, and drugs; (c) evaluation of new technologies; and (d) assessment of the need for new modalities and monitoring of their initial uses. The paper examines ways in which these roles are enhanced or threatened by evolving economic forces in the public and private sectors.

Phosphorylation Of The Neurospora Clock Protein Frequency Determines Its Degradation Rate And Strongly Influences The Period Length Of The Circadian Clock, Yi Liu, Jennifer Loros, Jay C. Dunlap

Dartmouth Scholarship

Under free running conditions, FREQUENCY (FRQ) protein, a central component of the Neurospora circadian clock, is progressively phosphorylated, becoming highly phosphorylated before its degradation late in the circadian day. To understand the biological function of FRQ phosphorylation, kinase inhibitors were used to block FRQ phosphorylation in vivo and the effects on FRQ and the clock observed. 6-dimethylaminopurine (a general kinase inhibitor) is able to block FRQ phosphorylation in vivo, reducing the rate of phosphorylation and the degradation of FRQ and lengthening the period of the clock in a dose-dependent manner. To confirm the role of FRQ phosphorylation in this clock …

Effect Of Ceftazidime On Systemic Cytokine Concentrations In Rats, Khalid M. Alkharfy, John A. Kellum, Reginald F. Frye, Gary R. Matzke

Pharmacotherapy and Outcomes Science Publications

The effect of a single dose of ceftazidime on circulating concentrations of interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) in a rat model of sepsis was studied. IL-6 concentrations were significantly elevated (100 to 200 times the baseline) 6 h after ceftazidime administration in both septic and nonseptic (control) rats. TNF-α concentrations increased significantly in nonseptic (∼40 times the baseline) rats but not septic (∼2 to 3 times the baseline) rats. Ceftazidime administration was not associated with an increase in endotoxin concentrations. These findings suggest that ceftazidime modulation of proinflammatory cytokine concentrations may be independent of its antimicrobial properties.

Whole Animal And Cellular Strategies In The Regulation Of Bone Mass In The Rat, Weidong Geng

Theses, Dissertations and Capstones

In order to determine the strategies in regulation of bone mass in the rat and better understand the pathophysiological mechanism of the postmenopausal osteoporosis, a series of studies were conducted at the whole animal and cellular level. At the whole animal level, female Sprague-Dawley rats were ovariectomized (Ovx) or sham-operated (control) at 18 weeks and the entire skeleton obtained at 24 weeks (baseline) or after an additional 31 day (28 week) interval on a normal (1.0%) or deficient (0.02%) calcium diet. Ovx rats on the normal calcium diet showed a 42% increase in whole body bone resorption and a 70% …

Isolation Of Current Components And Partial Reaction Cycles In The Glial Glutamate Transporter Eaat2, Thomas S. Otis, Michael Kavanaugh

Biomedical and Pharmaceutical Sciences Faculty Publications

The kinetic properties of the excitatory amino acid transporter EAAT2 were studied using rapid applications of l-glutamate to outside-out patches excised from transfected human embryonic kidney 293 cells. In the presence of the highly permeant anion SCN⁻, pulses of glutamate rapidly activated transient anion channel currents mediated by the transporter. In the presence of the impermeant anion gluconate, glutamate pulses activated smaller currents predicted to result from stoichiometric flux of cotransported ions. Both anion and stoichiometric currents displayed similar kinetics, suggesting that anion channel gating and stoichiometric charge movements are linked to early transitions in the transport cycle. …

Arginine 447 Plays A Pivotal Role In Substrate Interactions In A Neuronal Glutamate Transporter, Annie Bendahan, Ayelet Armon, Navid Madani, Michael Kavanaugh, Baruch I. Kanner

Biomedical and Pharmaceutical Sciences Faculty Publications

Glutamate transporters from the central nervous system play a crucial role in the clearance of the transmitter from the synaptic cleft. Glutamate is cotransported with sodium ions, and the electrogenic translocation cycle is completed by countertransport of potassium. Mutants that cannot interact with potassium are only capable of catalyzing electroneutral exchange. Here we identify a residue involved in controlling substrate recognition in the neuronal transporter EAAC-1 that transports acidic amino acids as well as cysteine. When arginine 447, a residue conserved in all glutamate transporters, is replaced by cysteine, transport of glutamate or aspartate is abolished, but sodium-dependent cysteine transport …

The Relationship Of Female Reproductive Hormones To Lumbopelvic Pain And Musculoskeletal Injuries In The Female Athlete, Christina M. Aksamit

Physical Therapy Scholarly Projects

The increased participation by females in athletics over the past decade, both competitively and leisurely, has brought attention to the number and severity of acquired injuries. Females tend to suffer a greater number of injuries than their male counterparts, and low back pain is also more prevalent in this population. Research is just beginning to focus on female athletes as their own separate entity. The female reproductive hormones have been targeted as a possible cause of many injuries secondary to the chemical and physical changes that occur with their fluctuations.

The purpose of this literature review is to identify the …
