Molecular Basis Of Mitochondrial Form And Function In The Hearts Of Antarctic Notothenioids That Vary In The Expression Of Hemoglobin And Myoglobin, Matthew R. Urschel
Molecular Basis Of Mitochondrial Form And Function In The Hearts Of Antarctic Notothenioids That Vary In The Expression Of Hemoglobin And Myoglobin, Matthew R. Urschel
Biological Sciences
Antarctic icefish (suborder Notothenioidei, family Channichthyidae) do not express hemoglobin (Hb), and 6 of the 16 members of this family do not express myoglobin (Mb) in their cardiac muscle. The loss of Hb and Mb correlates with an increase in mitochondrial volume density, a decrease in the mitochondrial surface-to-volume ratio and a decrease in the surface density of inner mitochondria) membranes in the hearts of icefishes compared to red-blooded notothenioids. We sought to understand the molecular mechanisms that regulate differences in mitochondrial density and morphology among the hearts of the notothenioids Notothenia coriiceps (+Hb/+Mb), Gobionotothen gibberifrons (+Hb/+Mb), Chaenocephalus aceratus ( …
Evolutionary Ecological Genetics Of Some Neotropical Birds, Matthew J. Miller
Evolutionary Ecological Genetics Of Some Neotropical Birds, Matthew J. Miller
Biological Sciences
Most of the current models to explain the diversification of Neotropical birds focus on physical barriers to gene flow. However, for any species the geographic structuring of populations is caused by an interaction between physical barriers to gene flow and a species' propensity to overcome those barriers. The three chapters presented in this dissertation provide three perspectives on this interaction and how it has shaped the diversification of some Neotropical birds. First, the widespread Neotropical lowland forest flycatcher Mionectes oleagineus had three phylogeographic splits across the Andes, resulting in four geographically structured lineages west of the Andes. At least two …
Lung Breathing In The Bullfrog: Generating Respiratory Rhythm And Pattern, Brittany L. Davies
Lung Breathing In The Bullfrog: Generating Respiratory Rhythm And Pattern, Brittany L. Davies
Biological Sciences
This research investigated location of the lung respiratory rhythm generator (RRG) in the bullfrog brainstem using neurokinin-1 (NK1R) and [mu]opioid ([mu]OR) receptor colocalization and characterized the role of these receptors in breathing pattern formation. colocalization was distinct near the facial nucleus in juvenile bullfrogs but not in tadpoles. NK1R intensity exhibited no developmental change, while [mu]OR intensity increased from late-stage tadpoles to juvenile frogs. Substance P (NK1R agonist; bath applied) increased lung burst frequency, lung burst cycle frequency (BCF), episode frequency, lung burst amplitude and area, but decreased number of lung bursts per episode and lung burst duration. Antagonist D …
Identification And Application Of Molecular Markers To Chum Salmon Population Genetics, Michael R. Garvin
Identification And Application Of Molecular Markers To Chum Salmon Population Genetics, Michael R. Garvin
Fisheries
I developed a new technique, DEco-TILLING (an adaptation of Eco-TILLING), to discover useful single nucleotide polymorphisms (SNPs) rapidly and inexpensively. Some chum salmon (Oncorhynchus keta) populations have declined in Western Alaska and in other areas of their geographic range. Possible reasons include climate shifts, by- catch in fisheries, and other perturbations. Genetics offers powerful tools that can be used to monitor this species on the high seas in stock mixtures aiding management of by- catch identification and other contributors to declines. Single nucleotide polymorphisms are a genetic marker that can be easily and rapidly surveyed on many individuals. Tools like …

In the 21st century, “Digital Children” (Edyburn, 2002) are growing up in a world rich with technology, including cell phones, iPods, email, PalmPilots, Web sites, discussion boards, chat rooms, the Internet, and electronic toys and learning games (Siraj-Blatchford & Whitebread, 2003). Young children whose families use technology acquire knowledge of and skills in language and literacy in part through exposure to technology in the home (Jewitt, 2006). For example, McGee and Richgels (2006) observed that many young children become aware of the existence of print and its use by their families in their daily lives through screen presentations on the …

Cityland – Vol. 5, No. 7, Center For New York City Law
CityLand - 2008
The August 2008 issue of CityLand covers significant land use and preservation developments in New York City. The City Council approved a compromise rezoning for Hudson Square and a rezoning for Mott Haven to allow 600 new housing units. A text amendment was passed to protect Carroll Gardens from out-of-context development. Proposed changes to the Hudson Yards zoning text drew criticism from elected officials and community boards. The Planning Commission approved a 63-story tower at 610 Lexington Avenue using air rights from the landmarked Seagram Building. A controversial redevelopment plan for East Harlem was criticized for proceeding without a selected …
Cd5 Plays An Inhibitory Role In The Suppressive Function Of Murine Cd4(+) Cd25(+) T(Reg) Cells., Trivikram Dasu, Joseph E Qualls, Halide Tuna, Chander Raman, Donald A Cohen, Subbarao Bondada
Cd5 Plays An Inhibitory Role In The Suppressive Function Of Murine Cd4(+) Cd25(+) T(Reg) Cells., Trivikram Dasu, Joseph E Qualls, Halide Tuna, Chander Raman, Donald A Cohen, Subbarao Bondada
Microbiology, Immunology, and Molecular Genetics Faculty Publications
A subset of CD4(+) T cells, the CD4(+) CD25(+) regulatory T (T(reg)) cells in the lymphoid organs and peripheral blood are known to possess suppressive function. Previous in vitro and in vivo studies have indicated that T cell receptor (TCR) signal is required for development of such 'natural regulatory (T(reg)) cells' and for activation of the effector function of CD4(+) CD25(+) regulatory T cells. CD5 is a cell surface molecule present on all T cells and a subtype of B lymphocytes, the B-1 cells, primarily localized to coelomic cavities, Peyer's patches, tonsils and spleen. CD5 acts as a negative regulator …

Incidence rates for adenocarcinomas of the esophagus and gastric cardia have been increasing rapidly, while rates for non‐cardia gastric adenocarcinoma and esophageal squamous cell carcinoma have declined. We examined food group intake as a risk factor for subtypes of esophageal and gastric cancers in a multicenter, population‐based case–control study in Connecticut, New Jersey and western Washington state. Associations between food groups and risk were estimated using adjusted odds ratios (OR), based on increasing intake of one serving per day. Total vegetable intake was associated with decreased risk of esophageal adenocarcinoma (OR = 0.85, 95% CI = 0.75, 0.96). Conversely, total …
Foraging Ecology Of American Oystercatchers In The Cape Romain Region, South Carolina, Christine Hand
Foraging Ecology Of American Oystercatchers In The Cape Romain Region, South Carolina, Christine Hand
All Theses
During the nonbreeding season, the Cape Romain Region of South Carolina supports ca. one-sixth of the total population of the eastern race (palliatus) of the American Oystercatcher (Haematopus palliatus), which consists of only ca. 11,000 individuals and appears to be declining. I compared the density, size, and orientation of the primary prey, Eastern oysters (Crassostrea virginica) and the foraging behaviors of adult American Oystercatchers among the three largest bays in the Cape Romain Region that American Oystercatchers used as foraging areas. Results indicated that prey size, prey orientation, and the foraging behaviors of American …

Spiny Lobsters Detect Conspecific Blood-Borne Alarm Cues Exclusively Through Olfactory Sensilla, Shkelzen Shabani, Michiya Kamio, Charles D. Derby
Peer Reviewed Articles
When attacked by predators, diverse animals actively or passively release molecules that evoke alarm and related anti-predatory behavior by nearby conspecifics. The actively released molecules are alarm pheromones, whereas the passively released molecules are alarm cues. For example, many insects have alarm-signaling systems that involve active release of alarm pheromones from specialized glands and detection of these signals using specific sensors. Many crustaceans passively release alarm cues, but the nature of the cues,sensors and responses is poorly characterized. Here we show in laboratory and field experiments that injured Caribbean spiny lobsters, Panulirus argus, passively release alarm cues via blood …
Emotions In The Classroom, Elizabeth D. Burris
Emotions In The Classroom, Elizabeth D. Burris
Theses, Dissertations, and Projects
This study explores the classroom emotional experience of five teachers. It is based on the assumptions that teaching is an emotional enterprise; that teaching necessarily involves "emotional labor," or the work of emotion management; that attending to and working through emotions (a form of emotion management) can influence how teachers teach; and that doing this emotional labor in a group setting can be useful to teachers. An additional assumption is that psychoanalytic concepts can help frame teachers' emotional experiences. The study looks specifically at how teachers' awareness and understanding of emotions affect their experience of teaching and what it is …

The Living And Spiritual Experiences Of Gay Men With Aids : An Exploratory Study, Jerry Dale Beene
Theses, Dissertations, and Projects
This research study will explore the experiences of ten gay men living with AIDS. Gay men with AIDS are a unique group in part because they are doubly stigmatized. Due to their sexual orientation, they have commonly experienced condemnation and marginalization, often from early on in their lives. My question for this study is: How does this particular group of men enduring this unique disease and treatment find and define their individual spirituality and sense of meaning as they face end of life issues? This qualitative research study used an exploratory, flexible methods design. I interviewed 10 gay men with …

Exploring Internalized Racism : A Critical Review Of The Literature And Implications For Clinical Social Work, Keshia Unika Williams
Exploring Internalized Racism : A Critical Review Of The Literature And Implications For Clinical Social Work, Keshia Unika Williams
Theses, Dissertations, and Projects
In social work, like many of its allied disciplines, the effects of racism on the racially oppressed has tended to focus on overt manifestations like violence and discrimination (Pyke and Dang, 2003). Largely missing from the mainstream social work literature is a clear and consistent definition and framework for internalized racism. An understanding of the deleterious effects of internalized racism- the subtle, often unconscious, processes by which racial inequality shapes the way that the oppressed think of themselves and other members of their group- is often lacking in clinical social work literature. Internalized racism represents a harmful consequence of a …

Examining Our Worst Fears, Jennifer Elmassian Leszkiewicz
Theses, Dissertations, and Projects
Fifty five graduate students in the 2008 class of Smith College School for Social Work, on average, seek symbolic immortality through existential themes, excluding religion. Additionally, the more students identify with themes that define meaning in their lives, the greater their fear of encountering threats to that meaning. Further, students reported that they daydream about existential fears that threaten symbolic immortality more frequently than they dream, or have memories of them; and that they dream about primal fears more frequently than they daydream, or have memories of them. This study tested the hypotheses that people fear what they imagine might …
