Sensory Deprivation Alters Aggrecan And Perineuronal Net Expression In The Mouse Barrel Cortex, Paulette A. Mccrae, Mary M. Rocco, Gail Kelly, Joshua C. Brumberg, Russell T. Matthews May 2007

Sensory Deprivation Alters Aggrecan And Perineuronal Net Expression In The Mouse Barrel Cortex, Paulette A. Mccrae, Mary M. Rocco, Gail Kelly, Joshua C. Brumberg, Russell T. Matthews

Publications and Research

An important role for the neural extracellular matrix in modulating cortical activity-dependent synaptic plasticity has been established by a number of recent studies. However, identification of the critical molecular components of the neural matrix that mediate these processes is far from complete. Of particular interest is the perineuronal net (PN), an extracellular matrix component found surrounding the cell body and proximal neurites of a subset of neurons. Because of the apposition of thePNto synapses and expression of this structure coincident with the close of the critical period, it has been hypothesized that nets could play uniquely important roles in synapse …


Secular Trends In The Association Of Socio-Economic Position With Self-Reported Dietary Attributes And Biomarkers In The Us Population: National Health And Nutrition Examination Survey (Nhanes) 1971–1975 To Nhanes 1999–2002, Ashima K. Kant, Barry I. Graubard Feb 2007

Secular Trends In The Association Of Socio-Economic Position With Self-Reported Dietary Attributes And Biomarkers In The Us Population: National Health And Nutrition Examination Survey (Nhanes) 1971–1975 To Nhanes 1999–2002, Ashima K. Kant, Barry I. Graubard

Publications and Research

Objective: Recent reports suggest persistence of health disparities related to socioeconomic position (SEP). To understand if diet may be a contributor to these trends, we examined secular trends in the association of diet and indicators of SEP from 1971–1975 to 1999–2002.

Design: We used data from the National Health and Nutrition Examination Surveys (NHANES) I (1971–1975), II (1976–1980), III (1988–1994) and 1999–2002 to examine the independent associations of poverty income ratio (PIR) and education with diet and biomarkers of diet and disease in 25–74-year-olds (n ¼ 36 600). We used logistic and linear regression methods to adjust for multiple covariates …


Maintenance Of Visual Stability In The Human Posterior Parietal Cortex, Erik Chang, Tony Ro Feb 2007

Maintenance Of Visual Stability In The Human Posterior Parietal Cortex, Erik Chang, Tony Ro

Publications and Research

Visual stability refers to our stable visuospatial perceptions despite the unstable visual input caused by saccades. Functional neuroimaging results, studies on patients with posterior parietal cortex (PPC) lesions, and single-unit recordings in the lateral intraparietal sulcus of primates indirectly suggest that the PPC might be a potential locus of visual stability through its involvement with spatial remapping. Here we directly explored the role of the PPC in visual stability by applying transcranial magnetic stimulation (TMS) while participants performed a perisaccadic displacement detection task. We show that TMS over the PPC but not a frontal control site alters sensitivity to displacement …


Strokes Of Existence: The Connection Of All Things, Mari Gorman Jan 2007

Strokes Of Existence: The Connection Of All Things, Mari Gorman

Graduate Student Publications and Research

Acted or real—and all life is real whether one is acting or not—the common denominator and consistent, ubiquitous reality of life and all behavior is that it manifests in the form of relationships on all scales. But what is a relationship? Until now, the answer to this question has not been sufficiently known. As a result of many years of empirical research that began with the aim of discovering what is going on in a gifted actor when s/he is playing a character that can be observed and experienced as a living, intuitive being, and based on the knowledge that …

Subtraction hybridization applied to a ‘differentiation therapy’ model of cancer employing human melanoma cells resulted in the cloning of melanoma differentiation associated gene-7/interleukin-24 (mda-7/IL-24). Initial studies confirm an inverse correlation between mda-7 expression and melanoma development and progression. Forced expression of mda-7 by means of a plasmid or via a replication incompetent adenovirus (Ad.mda-7) promotes growth suppression and induces apoptosis in a broad array of human cancers. In contrast, mda-7 does not induce growth suppressive or toxic effects in normal cells. Based on structure (containing an IL-10 signature motif), secretion by cells (including subsets of T-cells) and location on chromosome …


Does Increasing Biology Teacher Knowledge Of Evolution And The Nature Of Science Lead To Greater Advocacy For The Teaching Of Evolution In Schools?, Ross Nehm, Irvin Sam Schonfeld Jan 2007

Does Increasing Biology Teacher Knowledge Of Evolution And The Nature Of Science Lead To Greater Advocacy For The Teaching Of Evolution In Schools?, Ross Nehm, Irvin Sam Schonfeld

Publications and Research

This study investigated whether or not an increase in secondary science teacher knowledge about evolution and the nature of science gained from completing a graduate-level evolution course was associated with greater preference for the teaching of evolution in schools. Forty-four precertified secondary biology teachers participated in a 14-week intervention designed to address documented misconceptions identified by a precourse instrument. The course produced statistically significant gains in teacher knowledge of evolution and the nature of science and a significant decrease in misconceptions about evolution and natural selection. Nevertheless, teachers' postcourse preference positions remained unchanged; the majority of science teachers still preferred …


Foraging Ecology Of Black-Crowned Night-Herons (Nycticorax Nycticorax) In The New York City Area, Andrew James Bernick Jan 2007

Foraging Ecology Of Black-Crowned Night-Herons (Nycticorax Nycticorax) In The New York City Area, Andrew James Bernick

Dissertations, Theses, and Capstone Projects

Over 1,700 pairs of colonial wading birds (i.e., herons, egrets, and ibis) breed and forage in the industrialized ecosystem of metropolitan New York City (NYC). Wading bird colonies are located on 7 islands that lie between western Staten Island and Long Island Sound. The Black-crowned Night-Heron (BCNH), a mainly nocturnal forager, is the numerically dominant breeding heron in these colonies, and has been undergoing population declines both locally and region-wide since the mid-1990s. My objective was to determine how BCNHs forage in NYC's urban estuarine, freshwater, and terrestrial environments. From March-September 2002-2004, I conducted weekly night surveys on Staten Island, …

Pldb, A Putative Phospholipase D Homologue, Mediates Quorum Sensing In Dictyostelium Discoideum Development, Yi Chen

Dissertations, Theses, and Capstone Projects

Quorum sensing, the ability to measure the local cell density, is required for animal cells to achieve proper cell growth, differentiation and development. However, because of the genetic intractability of mammalian cells, we study quorum sensing in the genetically pliable unicellular eukaryote Dictyostelium discoideum. D. discoideum cells live as individual cells under vegetative conditions. Starvation sets off development to a multicellular organism. But cells won't develop unless enough cells are under starvation conditions. Approximately 105 cells are needed to form a fruiting body, the final stage of the development. When starved, cells are able to calculate the concentration …

Dissertations, Theses, and Capstone Projects

The guanine (G)-N2 DNA monoadduct of mitomycin C (MC), a cytotoxic anticancer drug, inhibits translesion bypass by DNA polymerases. 2,7-Diaminomitosene (2,7-DAM) is the major metabolite of MC in tumor cells, generated by the reduction of MC. 2,7-DAM alkylates DNA in the cell in situ, forming an adduct at the N7 position of 2'-deoxyguanosine (2,7-DAM-dG) and is noncytotoxic. In part I of this study we tested a potential correlation between the lack of cytotoxicity of 2,7-DAM and the relative ease of bypass of this adduct as compared with the MC adduct. 24-mer and 27-mer templates, adducted at a single …

The Effects Of Varying The Timing Of Inputs On A Neural Oscillator, Christina Ambrosio-Mouser, Farzan Nadim, Amitabha Bose Jan 2006

The Effects Of Varying The Timing Of Inputs On A Neural Oscillator, Christina Ambrosio-Mouser, Farzan Nadim, Amitabha Bose

Publications and Research

The gastric mill network of the stomatogastric ganglion of the crab Cancer borealis is comprised of a set of neurons that require modulatory input from outside the stomatogastric ganglion and input from the pyloric network of the animal in order to oscillate. Here we study how the frequency of the gastric mill network is determined when it receives rhythmic input from two different sources but where the timing of these inputs may differ. We find that over a certain range of the time difference one of the two rhythmic inputs plays no role what so ever in determining the network …


Daily Rhythm Of Cerebral Blood Flow Velocity, Deirdre A. Conroy, Arthur J. Spielman, Rebecca Q. Scott Mar 2005

Daily Rhythm Of Cerebral Blood Flow Velocity, Deirdre A. Conroy, Arthur J. Spielman, Rebecca Q. Scott

Publications and Research

Background: CBFV (cerebral blood flow velocity) is lower in the morning than in the afternoon and evening. Two hypotheses have been proposed to explain the time of day changes in CBFV: 1) CBFV changes are due to sleep-associated processes or 2) time of day changes in CBFV are due to an endogenous circadian rhythm independent of sleep. The aim of this study was to examine CBFV over 30 hours of sustained wakefulness to determine whether CBFV exhibits fluctuations associated with time of day.

Methods: Eleven subjects underwent a modified constant routine protocol. CBFV from the middle cerebral artery was monitored …
