What Can Phages Tell Us About Host-Pathogen Coevolution?, John J. Dennehy

Publications and Research

The outcomes of host-parasite interactions depend on the coevolutionary forces acting upon them, but because every host-parasite relation is enmeshed in a web of biotic and abiotic interactions across a heterogeneous landscape, host-parasite coevolution has proven difficult to study. Simple laboratory phage-bacteria microcosms can ameliorate this difficulty by allowing controlled, well-replicated experiments with a limited number of interactors. Genetic, population, and life history data obtained from these studies permit a closer examination of the fundamental correlates of host-parasite coevolution. In this paper, I describe the results of phage-bacteria coevolutionary studies and their implications for the study of host-parasite coevolution. Recent …

Meta-Analysis On The Effects Of Global Economic Growth On Birds In The Nations Of The Three Poles, Cynthia Gabriela Infante

Faculty

Economic and population growth as well as global macroeconomic policies are contributing to increasing global greenhouse gas (GHG) emissions. Climate change effects are more pronounced in cold regions such as the ‘Three Poles’ (the Arctic, the Antarctic and the Hindu Kush-Himalaya regions) than anywhere else. The Three Poles are rich in natural resources but the extraction of resources is degrading ecosystems and processes, and affecting species. In the Three Poles, many species depend on ice and snow habitats, but these species are competing with human activities for space and resources on a finite globe. Local and global pressures cause bird …

Digital Stone Exhibition: The Intersection Of Art & Technology, Robert Michael Smith

Nor’easter Conference

"Digital Stone" as a concept is based on the fusion of CAD technologies with traditional stone carving.

Digital Stone Exhibition featured four digital sculptors: Bruce Beasley, Jon Isherwood, Robert Michael Smith and Kenneth Snelson, who designed five sculptures each utilizing CAD technologies. All sculptures in this exhibition were designed and developed first in virtual space of software programs. Physical models were printed by rapid prototype machines which became a metaphorical "hand" of the computer to produce an actual sculpture from the virtual sculpture. The RP models were sent to China to be enlarged in granite at Dingli Stone Carving Company …

P21-Activated Kinase-1 Signaling Regulates Transcription Of Tissue Factor And Tissue Factor Pathway Inhibitor., Beatriz Sanchez-Solana, Mona Motwani, Da-Qiang Li, Jeyanthy Eswaran, Rakesh Kumar

Biochemistry and Molecular Medicine Faculty Publications

Tissue factor (TF) is a cell-surface glycoprotein responsible for initiating the coagulation cascade. Besides its role in homeostasis, studies have shown the implication of TF in embryonic development, cancer related events, and inflammation via coagulation-dependent and -independent (signaling) mechanisms. Tissue factor pathway inhibitor (TFPI) plays an important role in regulating TF-initiated blood coagulation. Therefore, transcriptional regulation of TF expression and its physiologic inhibitor TFPI, would allow us to understand the critical step that control many different processes. From a gene profiling study aimed to identify differentially regulated genes between wild type (WT) and p21-activated kinase 1-null (PAK1-KO) mouse embryonic fibroblasts …

Linking Old-Growth Forest Composition, Structure, Fire History, Climate And Land-Use In The Mountains Of Northern México, Citlali Cortes Montano, Peter Z. Fule, Donald A. Falk, Jose Villanueva-Diaz, Larissa L. Yocom Kent

Wildland Resources Faculty Publications

Old-growth forests are biologically and ecologically valuable systems that are disappearing worldwide at a rapid rate. México still holds large areas covered by temperate forests in the mountains of the Sierra Madre Occidental, but few of these retain old-growth characteristics. We studied four sites with remnant old-growth forests in Mesa de las Guacamayas, a site in the Sierra Madre Occidental in northwestern Chihuahua, to assess their composition, structure, and age characteristics. Overstory tree densities and basal areas at each site were based on measurements of all trees >1.3 m tall. The overstory was dominated by large Pinus durangensis, P. strobiformis, …

Novel Strategies To Improve Metabolic Parameters And Precondition Diabetic Hearts Against Ischemia/Reperfusion Injury, Amit Varma

Theses and Dissertations

Insulin resistance and chronic hyperglycemia promote vascular damage, increase circulating levels of inflammatory cytokines and lead to increased morbidity and mortality. MicroRNAs (miRs) -103/107 have been shown to negatively regulate insulin sensitivity and glucose homeostasis. Based on complimentary binding profiles, the downstream target gene of miR-103/107 is caveolin-1 (Cav-1). We hypothesized that daily administration of the phosphodiesterase-5 inhibitor tadalafil (TAD) ± the curcumin analogue (HO-3867) will attenuate inflammation, improve metabolic parameters and reduce infarct size after ischemia/reperfusion injury (IRI). Furthermore, we propose that TAD therapy will reduce myocardial expression of miR-103/107 and increase mRNA and protein levels of its target …

Environmental Science In Middle School Curricula: A Pilot Project In The Dominican Republic, Laura Tejeda

Theses

The Dominican Republic's (DR) public investment in education by 2010 was 2% of the GNP; falling behind the 6% minimum established by UNESCO in 2010 as a requirement to achieve quality education. The DR has not developed an Environmental Education policy. The DR's Environment Law 64-00 dictates Environmental Education to be introduced as one of the cross-cutting themes called "transverse axis" into the general curricula of all schools. However; due to lack of time and teachers able to integrate these axes into lesson plans, they were seldom implemented. This pilot project took place at The Community for Learning School (TCFL). …

Do Low-Mercury Terrestrial Resources Subsidize Low-Mercury Growth Of Stream Fish? Differences Between Species Along A Productivity Gradient, Darren M. Ward, Keith H. Nislow, Carol L. Folt

Dartmouth Scholarship

Low productivity in aquatic ecosystems is associated with reduced individual growth of fish and increased concentrations of methylmercury (MeHg) in fish and their prey. However, many stream-dwelling fish species can use terrestrially-derived food resources, potentially subsidizing growth at low-productivity sites, and, because terrestrial resources have lower MeHg concentrations than aquatic resources, preventing an increase in diet-borne MeHg accumulation. We used a large-scale field study to evaluate relationships among terrestrial subsidy use, growth, and MeHg concentrations in two stream-dwelling fish species across an in-stream productivity gradient. We sampled young-of-the-year brook trout ( Salvelinus fontinalis ) and Atlantic salmon ( Salmo salar …

Mindfulness-Based Stretching And Deep Breathing Exercises Normalize Serum Cortisol Levels And Reverse Symptoms Of Ptsd: A Prospective Randomized-Controlled Trial, Sang Hwan Kim

Health, Exercise, and Sports Sciences ETDs

Context: Cortisol, the human glucocorticoid, plays a key role in the pathophysiology of posttraumatic stress disorder (PTSD). It is known that individuals with chronic PTSD suffer from low basal cortisol levels. Endogenic normalization of basal cortisol concentration through exercise may have a therapeutic effect on treating PTSD symptoms, yet little is known about the association between exercise-induced endogenic increase of cortisol and PTSD symptom reduction. Objective: To identify whether mindfulness-based stretching and deep breathing exercise (MBX) increases basal cortisol levels, examine if MBX reduces PTSD symptom severity, and evaluate MBX as a complementary intervention for PTSD. Design: Prospective, randomized, controlled. …

Family Environment And School Environment As Predictors For Physical Aggression In Low-Income Children, Xiaoyu Li

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The purpose of the current study was to examine the unique and collective contributions of child’s own characteristics, their family environment and school environment to the development of child physical aggression at Grade 5. This study was based on Bronfenbrenner’s Process-Person-Context-Time model (Bronfenbrenner & Morris, 2006). Children’s gender and their aggression at age 3 were included as person characteristics. Family environment (primary caregiver’s ethnicity, maternal education, home warmth, physical punishment, exposure to violence, family conflict, and parent-child dysfunctional interaction) and early child care experience measured by whether the child was in child care at both age 3 and age 4 …

Learning Within A Computer-Assisted Instructional Environment: Effects On Multiplication Math Fact Mastery And Self-Efficacy In Elementary-Age Students, Loraine Jones Hanson

Theses and Dissertations

The primary purpose of this study was to evaluate the effect of basic multiplication mastery (0-12) and self-efficacy outcomes for elementary age students attempting to master multiplication facts in a Computer-Assisted Instructional (CAI) environment. Timez Attack (TA), a modern Internet based 3-D multiplication video game, was the computer program used in this study. Four third- and four fourth-grade classes of students at a public charter school received either 12 20-minute Teacher-Led Instructional (TLI), or TA multiplication practice sessions. Pre- and post Math Attitude Survey (MAS), timed multiplication tests, observations, and informal interviews were used to assess and compare TA and …

Direct writing includes a variety of processes that use different mechanisms to transfer materials on to substrates and can be generally distinguished from conventional rapid prototyping processes by a feature resolution in the sub-micron to micron range. The dispensing system studied in this thesis is a pneumatically actuated micro-extruder which is capable of processing a wide variety of materials. This material dispensing tool is capable of depositing small amounts of material to build three dimensional structures in an accurate …

Macroevolutionary Dynamics And Historical Biogeography Of Primate Diversification Inferred From A Species Supermatrix, Mark S. Springer, Robert Meredith, John Gatesy, Christopher A. Emerling, Jong Park, Daniel L. Rabosky, Tanja Stadler, Cynthia Steiner, Oliver A. Ryder, Jan E. Janečka, Colleen A. Fisher, William J. Murphy

Department of Biology Faculty Scholarship and Creative Works

Phylogenetic relationships, divergence times, and patterns of biogeographic descent among primate species are both complex and contentious. Here, we generate a robust molecular phylogeny for 70 primate genera and 367 primate species based on a concatenation of 69 nuclear gene segments and ten mitochondrial gene sequences, most of which were extracted from GenBank. Relaxed clock analyses of divergence times with 14 fossil-calibrated nodes suggest that living Primates last shared a common ancestor 71-63 Ma, and that divergences within both Strepsirrhini and Haplorhini are entirely post-Cretaceous. These results are consistent with the hypothesis that the Cretaceous-Paleogene mass extinction of non-avian dinosaurs …

Variation In Patterns Of Metal Accumulation In Thallus Parts Of Lessonia Trabeculata (Laminariales; Phaeophyceae): Implications For Biomonitoring, Ca Sáez, Mg Lobos, Ec Macaya, Et Al

School of Biological and Marine Sciences

Seaweeds are well known to concentrate metals from seawater and have been employed as monitors of metal pollution in coastal waters and estuaries. However, research showing that various intrinsic and extrinsic factors can influence metal accumulation, raises doubts about the basis for using seaweeds in biomonitoring programmes. The thallus of brown seaweeds of the order Laminariales (kelps) is morphologically complex but there is limited information about the variation in metal accumulation between the different parts, which might result in erroneous conclusions being drawn if not accounted for in the biomonitoring protocol. To assess patterns of individual metals in the differentiated …
