Forest Regeneration On The Osa Peninsula, Costa Rica, Manette E. Sandor Dec 2012

Forest Regeneration On The Osa Peninsula, Costa Rica, Manette E. Sandor

Master's Theses

Woody species diversity of secondary forest has the potential to converge with that found in old growth forest. This study is the first to examine multiple aspects of species and reproductive trait diversity, and their relationship to each other, across a successional chronosequence. Species richness and species diversity increases with increasing age of forest. Diaspore size and diversity as well as fruit size generally increased with increasing age of forest, but fruit size diversity did not. Abundance of animal-dispersed species increased whereas wind-dispersed species decreased in abundance over succession. Insect-pollinated individuals were most abundant overall. Diaspore diversity, pollination diversity, and …

The Posterior Hypothalamus Exerts Opposing Effects On Nociception Via The A7 Catecholamine Cell Group In Rats, Y. Jeong, J. R. Moes, M. Wagner, J. E. Holden Dec 2012

The Posterior Hypothalamus Exerts Opposing Effects On Nociception Via The A7 Catecholamine Cell Group In Rats, Y. Jeong, J. R. Moes, M. Wagner, J. E. Holden

University Faculty Publications and Creative Works

Stimulation of the posterior hypothalamic area (PH) produces antinociception in rats and humans, but the precise mechanisms are unknown. The PH forms anatomical connections with the parabrachial area, which contains the pontine A7 catecholamine cell group, a group of spinally projecting noradrenergic neurons known to produce antinociception in the dorsal horn. The aim of the present study was to determine whether PH-induced antinociception is mediated in part through connections with the A7 cell group in female Sprague-Dawley rats, as measured by the tail flick and foot withdrawal latency. Stimulation of the PH with the cholinergic agonist carbachol (125nmol) produced antinociception …

Understanding Affordances: History And Contemporary Development Of Gibson’S Central Concept, Dobromir Dotov, Lin Nie, Matthieu M. De Wit Dec 2012

Understanding Affordances: History And Contemporary Development Of Gibson’S Central Concept, Dobromir Dotov, Lin Nie, Matthieu M. De Wit

Journal Articles

Gibson developed the affordance concept to complement his theory of direct perception that stands in sharp contrast with the prevalent inferential theories of perception. A comparison of the two approaches shows that the distinction between them also has an ontological aspect. We trace the history and newer formalizations of the notion of affordance and discuss some competing opinions on its scope. Next, empirical work on the affordance concept is reviewed in brief and the relevance of dynamical systems theory to affordance research is demonstrated. Finally, the striking but often neglected convergence of the ideas of Gibson and those of certain …

Theranostic Oxygen Delivery Using Ultrasound And Microbubbles, James J. Kwan, Mehmet Kaya, Mark A. Borden, Paul A. Dayton Dec 2012

Theranostic Oxygen Delivery Using Ultrasound And Microbubbles, James J. Kwan, Mehmet Kaya, Mark A. Borden, Paul A. Dayton

Biomedical Engineering and Sciences Faculty Publications

Means to overcome tumor hypoxia have been the subject of clinical investigations since the 1960’s; however these studies have yet to find a treatment which is widely accepted. It has been known for nearly a century that hypoxic cells are more resistant to radiotherapy than aerobic cells, and tumor hypoxia is a major factor leading to the resistance of tumors to radiation treatment as well as several cytotoxic agents. In this manuscript, the application of ultrasound combined with oxygen-carrier microbubbles is demonstrated as a method to locally increase dissolved oxygen. Microbubbles can also be imaged by ultrasound, thus providing the …

Chronic Stress Elevates Telomerase Activity In Rats, Annaliese K. Beery, Jue Lin, Joshua S. Biddle, Darlene D. Francis, Elizabeth H. Blackburn, Elissa S. Epel Dec 2012

Chronic Stress Elevates Telomerase Activity In Rats, Annaliese K. Beery, Jue Lin, Joshua S. Biddle, Darlene D. Francis, Elizabeth H. Blackburn, Elissa S. Epel

Neuroscience: Faculty Publications

The enzyme telomerase lengthens telomeres—protective structures containing repetitive DNA sequences at chromosome ends. Telomere shortening is associated with diseases of ageing in mammals. Chronic stress has been related to shorter immune-cell telomeres, but telomerase activity under stress may be low, permitting telomere loss, or high, partially attenuating it. We developed an experimental model to examine the impacts of extended unpredictable stress on telomerase activity in male rats. Telomerase activity was 54 per cent higher in stressed rats than in controls, and associated with stress-related physiological and behavioural outcomes. This significant increase suggests a potential mechanism for resilience to stress-related replicative …

Role Of Deg/Enac Channels Expressed In Glia In C. Elegans Touch Sensitivity, Lu Han Dec 2012

Role Of Deg/Enac Channels Expressed In Glia In C. Elegans Touch Sensitivity, Lu Han

Open Access Dissertations

Neuronal DEG/ENaC Na+ channels have been implicated in touch sensation. For example, MEC-4 is expressed in touch neurons in C. elegans and mediates gentle touch response. Similarly, homologous mammalian ASIC2 and ASIC3 are expressed in sensory neurons and produce touch phenotypes when knocked out in mice. Here, we show that novel DEG/ENaC subunits DELM-1 and DELM-2 are expressed in glia associated with touch neurons in C. elegans and that their knock-out causes defects in mechanosensory behaviors related to nose touch and foraging, which are mediated by OLQ and IL1 sensory neurons. Cell-specific rescue supports the idea that DELM-1 and DELM-2 …

Genomic Loss Of Tumor Suppressor Mirna-204 Promotes Cancer Cell Migration And Invasion By Activating Akt/Mtor/Rac1 Signaling And Actin Reorganization, Saadi J. Imam, Jason R. Plyler, Hima Bansal, Suresh Prajapati, Sanjay Bansal, Jennifer Rebeles, Jeffrey S. Dome, +12 Additional Authors

Pediatrics Faculty Publications

Increasing evidence suggests that chromosomal regions containing microRNAs are functionally important in cancers. Here, we show that genomic loci encoding miR-204 are frequently lost in multiple cancers, including ovarian cancers, pediatric renal tumors, and breast cancers. MiR-204 shows drastically reduced expression in several cancers and acts as a potent tumor suppressor, inhibiting tumor metastasis in vivo when systemically delivered. We demonstrated that miR-204 exerts its function by targeting genes involved in tumorigenesis including brain-derived neurotrophic factor (BDNF), a neurotrophin family member which is known to promote tumor angiogenesis and invasiveness. Analysis of primary tumors shows that increased expression …

Multiple Subject Barycentric Discriminant Analysis (Musubada): How To Assign Scans To Categories Without Using Spatial Normalization, Hervé Abdi, Lynne J. Williams, Andrew C. Connolly, M. Ida Gobbini Dec 2012

Multiple Subject Barycentric Discriminant Analysis (Musubada): How To Assign Scans To Categories Without Using Spatial Normalization, Hervé Abdi, Lynne J. Williams, Andrew C. Connolly, M. Ida Gobbini

Dartmouth Scholarship

We present a new discriminant analysis (DA) method called Multiple Subject Barycentric Discriminant Analysis (MUSUBADA) suited for analyzing fMRI data because it handles datasets with multiple participants that each provides different number of variables (i.e., voxels) that are themselves grouped into regions of interest (ROIs). Like DA, MUSUBADA (1) assigns observations to predefined categories, (2) gives factorial maps displaying observations and categories, and (3) optimally assigns observations to categories. MUSUBADA handles cases with more variables than observations and can project portions of the data table (e.g., subtables, which can represent participants or ROIs) on the factorial maps. Therefore MUSUBADA can …

Black Students' Classroom Silence In Predominantly White Institutions Of Higher Education, Mahajoy A. Laufer Dec 2012

Black Students' Classroom Silence In Predominantly White Institutions Of Higher Education, Mahajoy A. Laufer

Theses, Dissertations, and Projects

This qualitative study explored Black students' silence in classrooms at predominantly white institutions (PWIs) of higher education in the northeast United States. Fifteen student interviews revealed that teaching material centered on European-American culture and history influenced their silence. Participants perceived devaluing of people of color in course material and perceived that professors used and allowed racist language and opinions to pervade the classroom. Students negotiated the tension of having discordant views from the mainstream and at times, between other students of the same racial and cultural group. They often elected to speak out against perceived discrimination and remained silent in …
