© 2015 American Society of Plant Biologists. All rights reserved. The best-characterized members of the plant-specific SIAMESE-RELATED (SMR) family of cyclin-dependent kinase inhibitors regulate the transition from the mitotic cell cycle to endoreplication, also known as endoreduplication, an altered version of the cell cycle in which DNA is replicated without cell division. Some other family members are implicated in cell cycle responses to biotic and abiotic stresses. However, the functions of most SMRs remain unknown, and the specific cyclin- dependent kinase complexes inhibited by SMRs are unclear. Here, we demonstrate that a diverse group of SMRs, including an SMR from …

Cellular And Molecular Remodeling Of Inguinal Adipose Tissue Mitochondria By Dietary Methionine Restriction, Yuvraj N. Patil, Kelly N. Dille, David H. Burk, Cory C. Cortez, Thomas W. Gettys

Faculty Publications

© 2015 Elsevier Inc. Dietary methionine restriction (MR) produces a coordinated series of biochemical and physiological responses that improve biomarkers of metabolic health, increase energy expenditure, limit fat accretion and improve overall insulin sensitivity. Inguinal white adipose tissue (IWAT) is a primary target and site of action where the diet initiates transcriptional programs linked to enhancing both synthesis and oxidation of lipid. Using a combination of ex vivo approaches to assess dietary effects on cell morphology and function, we report that dietary MR produced a fourfold increase in multilocular, UCP1-expressing cells within this depot in conjunction with significant increases in …

Lithologic Discontinuity Assessment In Soils Via Portable X-Ray Fluorescence Spectrometry And Visible Near-Infrared Diffuse Reflectance Spectroscopy, David C. Weindorf, Somsubhra Chakraborty, Abdalsamad Abdalsatar, Ali Aldabaa, Laura Pau Lette, Giuseppe Corti, Stefania Cocco, Erika Michéli, Dandan Wang, Bin Li, Titus Man, Aakriti Sharma, Taylor Person

Faculty Publications

Lithologic discontinuity identification can be arduous and erroneous in instances where distinct morphological differences between parent materials are absent. Often, investigators must wait for laboratory data to help differentiate parent materials via physicochemical properties. This study used visible near-infrared diffuse reflectance spectroscopy (VisNIR DRS) and portable X-ray fluorescence (PXRF) spectrometry for establishing parent material differentia more quickly. Ten pedons containing 135 samples were scanned in situ in the United States, Italy, and Hungary, morphologically described by trained pedologists, then sampled for standard laboratory characterization. Compared with laboratory data and/or morphologically described discontinuities, PXRF data were associated with large, abrupt changes …

Changes In Habitat Use At Rain Forest Edges Through Succession: A Case Study Of Understory Birds In The Brazilian Amazon, Luke L. Powell, Gustavo Zurita, Jared D. Wolfe, Erik I. Johnson, Philip C. Stouffer

Faculty Publications

Primary tropical rain forests are being rapidly perforated with new edges via roads, logging, and pastures, and vast areas of secondary forest accumulate following abandonment of agricultural lands. To determine how insectivorous Amazonian understory birds respond to edges between primary rain forest and three age classes of secondary forest, we radio-tracked two woodcreepers (Glyphorynchus spirurus, N = 17; Xiphorhynchus pardalotus, N = 18) and a terrestrial antthrush (Formicarius colma, N = 19). We modeled species-specific response to distance to forest edge (a continuous variable) based on observations at varying distances from the primary-secondary forest interface. All species avoided 8-14-yr-old secondary …

The Downregulation Of Short Neuropeptide Receptor (Snpfr) In The Red Imported Fire Ant Solenopsis Invicta (Hymenoptera: Formicidae) And The Tawny Crazy Ant Nylanderia Fulva (Hymenoptera: Formicidae) Using Rna Interference, And The Use Of An Anthranilic Diamide As A Novel Management Technique, Megan Rudolph

Biology Theses

The red imported fire ant, Solenopsis invicta Buren (Hymenoptera: Formicidae), is an invasive species endemic to South America that was inadvertently introduced into the United States. This invasive species costs over six billion dollars (USD) annually and causes substantial ecological and agricultural damage. Anthranilic diamides are novel chemical insecticides that selectively target the insect ryanodine receptor in the endoplasmic reticulum, causing calcium release and insect mortality. In this study, cyclaniliprole, an anthranilic diamide, was used to cause significant mortality in S. invicta workers. RNA interference (RNAi) is a known regulator of biological systems in insects and was also used in …

Background: Charts of size at birth are used to assess the postnatal growth of preterm babies on the assumption that extrauterine growth should mimic that in the uterus.

Methods: The INTERGROWTH-21st Project assessed fetal, newborn, and postnatal growth in eight geographically defined populations, in which maternal health care and nutritional needs were met. From these populations, the Fetal Growth Longitudinal Study selected low-risk women starting antenatal care before 14 weeks’ gestation and monitored fetal growth by ultrasonography. All preterm births from this cohort were eligible for the Preterm Postnatal Follow-up Study, which included standardised anthropometric measurements, feeding practices based on …

Increased Taxonomic And Functional Similarity Does Not Increase The Trophic Similarity Of Communities, Thomas K. Pool, Julien Cucherousset, Stéphanie Boulêtreau, Sébastien Villéger, Angela L. Strecker, Gaël Grenouillet

Environmental Science and Management Faculty Publications and Presentations

Aim: Despite a long-standing research interest in the association between the biodiversity (i.e. taxonomic and functional composition) and trophic structure of communities, our understanding of the relationship remains limited. Community assembly theory predicts that niche partitioning will result in communities with a diverse array of functional traits, which in turn may facilitate a correspondingly diverse array of trophic interactions that define the trophic niche of those communities. The aim of our study is to test this prediction.

Methods: We built a database composed of functional traits and stable isotope values (δ¹³C and δ¹⁵N) for …

Chewed Out: An Experimental Link Between Food Material Properties And Repetitive Loading Of The Masticatory Apparatus In Mammals, Matthew J. Ravosa, Jeremiah E. Scott, Kevin R. Mcabee, Anna J. Veit, Annika L. Fling

Publications

Using a model organism (rabbits) that resembles a number of mammalian herbivores in key aspects of its chewing behaviors, we examined how variation in dietary mechanical properties a ects food breakdown during mastication. Such data have implications for understanding phenotypic variation in the mammalian feeding apparatus, particularly with respect to linking jaw form to diet-induced repetitive loading. Results indicate that chewing frequency (chews/s) is independent of food properties, whereas chewing investment (chews/g) and chewing duration(s), which are proportional to repetitive loading of the jaws, are positively related to food sti ness and toughness. In comparisons of displacement-limited and stress-limited fragmentation …

Three New Reports Of Subsocial Tortoise Beetles From South America (Chrysomelidae: Cassidinae), Margarete V. Macedo, Vivian Flinte, André Abejanella, Caroline S. Chaboo

Department of Entomology: Faculty Publications

Subsociality is known in 35 species in 10 genera of the chrysomelid subfamilies Cassidinae and Chrysomelinae. In Cassidinae, the behavior is clustered in two tribes, Eugenysini and Mesomphaliini, but unknown biologies of many of these species limit fine-scaled resolution of the origins and diversity of this interesting behavior. We report three new records of subsocial Cassidinae, Eugenysa martae Borowiec in Colombia, Omaspides (Omaspides) clathrata L. in French Guiana, and Paraselenis (S.) aulica in Brazil. Females guard larvae and pupae; larvae retain exuvio-fecal shields in some stages. Longer-term study of P. (S.) aulica on the host Ipomoea (Convolvulaceae) revealed …

Raman Spectroscopy For Screening And Diagnosis Of Cervical Cancer, Fiona Lyng, Damien Traynor, Ines Rm Ramos, Franck Bonnier, Hugh Byrne

Articles

Cervical cancer is the fourth most common cancer in women worldwide and mainly affects younger women. The mortality associated with cervical cancer can be reduced if this disease is detected at the pre-cancer stage. Current gold standard methods include cytopathology, HPV testing and histopathology but these methods are limited in terms of subjectivity, cost and time. There is an unmet clinical need for new methods to aid clinicians in the early detection of cervical pre-cancer. These methods should be objective, rapid and require minimal sample preparation. Raman spectroscopy is a vibrational spectroscopic technique by which incident radiation is used to …

Neurology Articles

MRI estimates of extracellular volume and tumor exudate flux in peritumoral tissue are demonstrated in an experimental model of cerebral tumor. Peritumoral extracellular volume predicted the tumor exudate flux. Eighteen RNU athymic rats were inoculated intracerebrally with U251MG tumor cells and studied with dynamic contrast enhanced MRI (DCE-MRI) approximately 18 days post implantation. Using a model selection paradigm and a novel application of Patlak and Logan plots to DCE-MRI data, the distribution volume (i.e. tissue porosity) in the leaky rim of the tumor and that in the tissue external to the rim (the outer rim) were estimated, as was the …

Reclaiming Lost Territory: The Response Of Owyhee Harvester Ants To Forager Intrusions By Neighboring Colonies, Brett D. Howell, Ian C. Robertson

Biology Faculty Publications and Presentations

Neighboring colonies of the Owyhee harvester ant, Pogonomyrmex salinus, often share nonoverlapping foraging boundaries in the areas between their nests. We found that interactions between neighbors along these foraging boundaries were infrequent but peaceful, and usually resulted in one or both individuals becoming agitated and scurrying away in opposite directions. Interactions between neighbors were necessary to maintain the foraging ranges of their respective colonies. An exclusion experiment showed that when one colony of a pair situated 5-7 m apart was denied access to its foraging range, individuals from the other colony would usually (i.e., in 7 out of 10 cases) …

Detection Of Acute Nervous System Injury With Advanced Diffusion-Weighted Mri: A Simulation And Sensitivity Analysis, Nathan P. Skinner, Shekar N. Kurpad, Brian D. Schmit, Matthew D. Budde

Biomedical Engineering Faculty Research and Publications

Diffusion-weighted imaging (DWI) is a powerful tool to investigate the microscopic structure of the central nervous system (CNS). Diffusion tensor imaging (DTI), a common model of the DWI signal, has a demonstrated sensitivity to detect microscopic changes as a result of injury or disease. However, DTI and other similar models have inherent limitations that reduce their specificity for certain pathological features, particularly in tissues with complex fiber arrangements. Methods such as double pulsed field gradient (dPFG) and q-vector magic angle spinning (qMAS) have been proposed to specifically probe the underlying microscopic anisotropy without interference from the macroscopic tissue organization. …

A Qualitative Grounded Theory Study In Understanding The Teacher/Student Relationship In The College English Freshman Composition Classroom, Jean Tweedy

This qualitative grounded theory study is focused on the teacher/student relationship that develops in a freshman composition class when writing is being taught and how that relationship exists during the writing process. Notes were generated through field observation of three freshman English 101 classes, personal interviews with 12 students who were members of the three freshman English 101 classes observed by me, and final grade records for each student in each class obtained from the registrar’s office. The ability and perceived willingness of the English teacher to communicate with students is the prime motivating factor for confidence within the students …

The Effect Of A Minimum Credit Diploma Pathway On High School Graduation Rate, Teresa Strickland

Doctoral Dissertations and Projects

There are many paths to high school graduation. The reauthorization of the Elementary and Secondary Education Act has driven schools to be creative in seeking strategies by which students successfully earn their high¬¬¬¬ school diploma. In this non-experimental, causal-comparative study, a large Western North Carolina school district utilizes a minimum credit diploma to help students who previously experienced repeated academic failure achieve high school graduation by earning 21 course credits. The district requires traditional diploma-seeking students to earn seven additional credits to the 21 required by the State. Participants included high school graduates from the 2013-2014 school year. Both traditional …

Sloterdijk: You Must Change Your Life. On Anthropotechnics; In The World Interior Of Capital. For A Philosophical Theory Of Globalization; Globes: Spheres Ii: Macrospherology, Pieter Lemmens

International Dialogue

Although the German philosopher Peter Sloterdijk (1947) is certainly still not a well-known, let alone “settled” author within the Anglophone philosophical community that leans toward what is still frequently called “continental philosophy,” unlike similarly important figures such as Jean-Luc Nancy, Bruno Latour, Alain Badiou, Giorgio Agamben, Niklas Luhmann and Axel Honneth, his star is nevertheless slowly rising and many of his books have been translated in English in recent years. One of the reasons for this delayed reception in Anglophone academia might be Sloterdijk’s highly idiosyncratic approach to philosophy, his even more idiosyncratic, lavishly exuberant, intensely literary and (in my …
