Plasticity Of The Reproductive Axis Caused By Social Status Change In An African Cichlid Fish: I. Pituitary Gonadotropins, Karen P. Maruska, Berta Levavi-Sivan, Jakob Biran, Russell D. Fernald

Faculty Publications

Social position in a dominance hierarchy is often tightly coupled with fertility. Consequently,ananimal that can recognize and rapidly take advantage of anopportunity to rise inrankwillhaveareproductive advantage. Reproduction in all vertebrates is controlled by the brain-pituitary-gonad axis,andin males of the African cichlid fish Astatotilapia burtoni, GnRH1 neurons at the apex of this axis are under social control. However, little is known about how quickly social information is transformed into functional reproductive change, or about how socially controlled changes in GnRH1 neurons influence downstream actions of the brain-pituitary-gonad axis. We created an opportunity for reproductively suppressed males to ascend in status and …

Faculty Senate Newsletter, January 2011, Louisiana State University And Agricultural & Mechanical College

LSU Faculty Senate Publications

Message from the President: Brutus, when consigning Caesar to eternity, seeks attention from friends, Romans, and countrymen, asking them to lend him their ears. Had he been living in Baton Rouge in 2011, he might well have added to that list “coalitions,” the Flagship Coalition being the newest among the many supporters and compatriots seeking citizenship in the Tiger Empire. Brutus, of course, was himself not the most dependable of friends; he called for numerous “ears” knowing well that listening would be a wise strategy in turbulent times. He offered a list of affiliated parties—friends, Romans, and countrymen— suspecting that …

How Incipient Colonies Create Territory: The Textual Surveys Of New Spain, 1520s–1620s, Andrew Sluyter, Richard Hunter

Faculty Publications

The study of colonial surveying and cartography has become key to understanding the history of European colonialism because of the recognition that land surveys and maps not only represent territory but form part of the process through which territory comes into being. While many studies have therefore focused on the history of instrumental surveying and cartography in New Spain, roughly equivalent to present-day Mexico, between the seventeenth and twentieth century, the textual surveys of the sixteenth century that helped to bring the initial colonial territory into being have gone largely unstudied. Content analysis of textual land surveys included in sixteenth-century …

Application Of A Novel Boronated Porphyrin (H2Ocp) As A Dual Sensitizer For Both Pdt And Bnct, Ryo Hiramatsu, Shinji Kawabata, Shin Ichi Miyatake, Toshihiko Kuroiwa, Michael W. Easson, M. Graça H. Vicente

Faculty Publications

Background: and Objective Boronated porphyrins have emerged as promising dual sensitizers for use in both photodynamic therapy (PDT) and boron neutron capture therapy (BNCT), by virtue of their known tumor affinity, low cytotoxicity in dark conditions, and easy synthesis with high boron content. Octa-anionic 5,10,15,20-tetra[3,5-(nido-carboranylmethyl)phenyl] porphyrin (H2OCP) is a boronated porphyrin having eight boron clusters linked to the porphyrin ring. To evaluate H2OCP's applicability to both PDT and BNCT, we performed an in vitro and ex vivo study using F98 rat glioma cells. Materials and Methods We examined the time-dependent cellular uptake of H 2OCP by measuring the boron concentration …

Virus-Derived Sirnas And Pirnas In Immunity And Pathogenesis, Shou Wei Ding, Rui Lu

Faculty Publications

Cellular organisms have evolved related pathways for the biogenesis and function of small interfering RNAs (siRNAs), microRNAs and PIWI-interacting RNAs (piRNAs). These distinct classes of small RNAs guide specific gene silencing at both transcriptional and posttranscriptional levels by serving as specificity determinants. Small RNAs of virus and host origins have been found to modulate virus-host interactions by RNA interference (RNAi), leading to antiviral immunity or viral pathogenesis. Deep sequencing-based profiling of virus-derived small RNAs as products of host immune recognition not only allowed us to gain insight into the expansion and functional specialization of host factors involved in the antiviral …

Oncogenic Potential Of Yin Yang 1 Mediated Through Control Of Imprinted Genes, Michelle M. Thiaville, Joomyeong Kim

Faculty Publications

The transcription factor Yin Yang (YY) 1 is one of the most evolutionarily well-conserved DNA binding proteins that is ubiquitously expressed among different tissue types. YY1 functions as a critical regulator for a diverse set of genes, making its role in the cancerous environment elusive. Recent studies have demonstrated that clusters of YY1 binding sites are overrepresented in imprinted gene loci. These clustered binding sites may function as a molecular rheostat with respect to YY1 protein levels. YY1 levels were documented to be altered in various tumor tissues in conjunction with the transcriptional levels of the imprinted genes it regulates. …

Clark, Daniel Strickman

Faculty Publications

The goal of this study was to evaluate the effectiveness of a public health educational campaign to reduce backyard mosquito-larval habitats. Three communities each, within two New Jersey counties, were randomly selected to receive: (1) both education and mosquito control, (2) education only, and (3) no education or mosquito control. Four separate educational events included a 5-day elementary school curriculum in the spring, and three door to door distributions of educational brochures. Before and after each educational event, the numbers of mosquito-larval container habitats were counted in 50 randomly selected homes per study area. Container surveys allowed us to measure …

“Describing Our Whole Experience”: The Statistical Philosophies Of W.F.R. Weldon And Karl Pearson, Charles H. Pence

Faculty Publications

There are two motivations commonly ascribed to historical actors for taking up statistics: to reduce complicated data to a mean value (e.g., Quetelet), and to take account of diversity (e.g., Galton). Different motivations will, it is assumed, lead to different methodological decisions in the practice of the statistical sciences. Karl Pearson and W. F. R. Weldon are generally seen as following directly in Galton’s footsteps. I argue for two related theses in light of this standard interpretation, based on a reading of several sources in which Weldon, independently of Pearson, reflects on his own motivations. First, while Pearson does approach …

Nietzsche’S Aesthetic Critique Of Darwin, Charles H. Pence

Faculty Publications

Despite his position as one of the first philosophers to write in the “post- Darwinian” world, the critique of Darwin by Friedrich Nietzsche is often ignored for a host of unsatisfactory reasons. I argue that Nietzsche’s critique of Darwin is important to the study of both Nietzsche’s and Darwin’s impact on philosophy. Further, I show that the central claims of Nietzsche’s critique have been broadly misunderstood. I then present a new reading of Nietzsche’s core criticism of Darwin. An important part of Nietzsche’s response can best be understood as an aesthetic critique of Darwin, reacting to what he saw as …

Influence Of Cortisol On The Attachment And Metamorphosis Of Larval Utterbackia Imbecillis On Bluegill Sunfish (Lepomis Macrochirus), Benjamin Dubansky, Brian Whitaker, Fernando Galvez

Faculty Publications

The larvae of unionid freshwater mussels (i.e., glochidia) undergo a parasitic stage requiring their attachment to the external epithelia of fish hosts, where they metamorphose into free-living juveniles. We describe the physiological effects in bluegill sunfish (Lepomis macrochirus) of infection with glochidia from the paper pondshell (Utterbackia imbecillis). Glochidia accumulation on bluegill increased dramatically at concentrations of 2000 glochidia liter-1 and above, reaching a maximum attachment density of about 30 glochidia g-1 fish at 4000 glochidia liter-1. Plasma cortisol was the most sensitive indicator of biological effect to glochidial exposure, increasing significantly in hosts exposed to 2000 glochidia liter-1 or …

Outlook For Development Of High-Throughput Cryopreservation For Small-Bodied Biomedical Model Fishes, Terrence R. Tiersch, Huiping Yang, E. Hu

Faculty Publications

With the development of genomic research technologies, comparative genome studies among vertebrate species are becoming commonplace for human biomedical research. Fish offer unlimited versatility for biomedical research. Extensive studies are done using these fish models, yielding tens of thousands of specific strains and lines, and the number is increasing every day. Thus, high-throughput sperm cryopreservation is urgently needed to preserve these genetic resources. Although high-throughput processing has been widely applied for sperm cryopreservation in livestock for decades, application in biomedical model fishes is still in the concept-development stage because of the limited sample volumes and the biological characteristics of fish …

Sperm Quality Assessments For Endangered Razorback Suckers Xyrauchen Texanus, Jill A. Jenkins, Bruce E. Eilts, Amy M. Guitreau, Chester R. Figiel, Rassa O. Draugelis-Dale, Terrence R. Tiersch

Faculty Publications

Flow cytometry (FCM) and computer-assisted sperm motion analysis (CASA) methods were developed and validated for use with endangered razorback suckers Xyrauchen texanus collected (nZ64) during the 2006 spawning season. Sperm motility could be activated within osmolality ranges noted during milt collections (here 167-343 mOsm/kg). We hypothesized that sperm quality of milt collected into isoosmotic (302 mOsm/kg) or hyperosmotic (500 mOsm/kg) Hanks' balanced salt solution would not differ. Pre-freeze viabilities were similar between osmolalities (79%G6 (S.E.M.) and 76%G7); however, post-thaw values were greater in hyperosmotic buffer (27%G3 and 12%G2; PZ0.0065), as was mitochondrial membrane potential (33%G4 and 13%G2; PZ0.0048). Visual estimates …

Evaluation Of Dry Matter, Protein, Starch, Sucrose, Β-Carotene, Iron, Zinc, Calcium, And Magnesium In East African Sweetpotato [Ipomoea Batatas (L.) Lam] Germplasm, Silver Tumwegamire, Regina Kapinga, Patrick R. Rubaihayo, Don R. Labonte, Wolfgang J. Grüneberg, Gabriela Burgos, Thomas Zum Felde, Rosemary Carpio, Elke Pawelzik, Robert O.M. Mwanga

Faculty Publications

The present study evaluated selected East African (EA) sweetpotato varieties for storage root dry matter and nutrient content and obtained information on the potential contributions of the varieties to alleviate vitamin A and mineral deficiencies. Roots obtained from 89 farmer (white- and orange-fleshed) varieties and one introduced variety ('Resisto') were analyzed for storage root quality using near-infrared reflectance spectroscopy technology. Location differences were only significant for starch content. The σ2G variance was significant (P < 0.01) for all the traits except sucrose content. Overall, the farmer varieties had higher dry matter, higher starch, and lower sucrose contents than the control clone, 'Resisto'. It is these qualities that make sweetpotato attractive as a starchy staple in EA. A low population's mean β-carotene content (19.0 ppm)was observed.However, deep orange-fleshed farmer varieties, 'Carrot_C', 'Ejumula', 'Carrot Dar', 'Mayai', and 'Zambezi', had β-carotene content that can meet 350% or greater of recommended daily allowance (RDA) with 250-g serving to a 5- to 8-year-old child. More but light orange-fleshed farmer varieties 'K-118', 'K-134', 'K-46', 'KMI61', 'MLE162 Nakahi', 'PAL161', 'Sowola6', 'Sponge', 'SRT34 Abuket2', 'SRT35 Anyumel', 'SRT52', and 'Sudan' can provide 50% to 90% RDA of pro-vitamin A for the child. The root minerals' content was generally low except for magnesium whose content can meet 50% or greater RDA in many farmer varieties. However, in areas with high sweetpotato consumption, varieties 'Carrot_C', 'Carrot Dar', 'KRE nylon', 'MLE163 Kyebandula', and 'SRT49 Sanyuzameza' can make good intakes of iron, zinc, calcium, and magnesium. In conclusion, some EA farmer varieties can contribute greatly to alleviation of vitamin A deficiency and substantial mineral intakes.
