Developmental Cognitive Neuroscience Laboratory: Faculty and Staff Publications
The majority of epidemiological studies of breast feeding have been conducted in healthy, fullterm infant samples. Little is known about the incidence and correlates of breast milk feeding in preterm infants, particularly in those born outside of metropolitan areas. Therefore, hospital medical charts of 151 consecutively admitted preterm infants (
Effects Of Environmental Measures On Intelligence In Young Children: Growth Curve Modeling Of Longitudinal Data, K. A. Espy, Victoria J. Molfese, L. Dilalla
Effects Of Environmental Measures On Intelligence In Young Children: Growth Curve Modeling Of Longitudinal Data, K. A. Espy, Victoria J. Molfese, L. Dilalla

Examined the effects of different environmental measures on individual intellectual growth patterns in 105 young children participating in a longitudinal study. Intelligence (Stanford-Binet, 4th edition) was measured at ages 3 through 6 yrs, and child's environment was assessed at age 3 years using SES data and scores on the Home Observation for Measurement of the Environment (HOME) Inventory. Growth curve analyses revealed that HOME scores exerted a constant influence on the expected composite, verbal, and nonverbal intellectual skills at each age. Only SES influenced the rate of growth, specifically nonverbal intellectual skills. The magnitudes of these effects were moderate, but …
Effects Of Neurobehavioral Assessment On Feeding And Weight Gain In Preterm Neonates, T. E. Senn, K. A. Espy
Effects Of Neurobehavioral Assessment On Feeding And Weight Gain In Preterm Neonates, T. E. Senn, K. A. Espy
Developmental Cognitive Neuroscience Laboratory: Faculty and Staff Publications
Neonatal intensive care unit personnel and parents often are concerned that developmental assessment will tire preterm neonates and impair their feeding ability and subsequent weight gain. Therefore, the amount of fluid consumed by 108 preterm neonates (≤36.5 wk gestational age) was compared before and after administration of the Neurobehavioral Assessment of the Preterm Infant (NAPI). In addition, the weight gain of 35 preterm neonates who were administered the NAPI was compared with that of a matched control group of 35 preterm neonates who were not administered the NAPI. There were no differences in the amount of fluid consumed before and …
Osmosensitive Taurine Release: Does Taurine Share The Same Efflux Pathway With Chloride And Other Amino Acid Osmolytes?, Rodrigo Franco
Osmosensitive Taurine Release: Does Taurine Share The Same Efflux Pathway With Chloride And Other Amino Acid Osmolytes?, Rodrigo Franco
School of Veterinary and Biomedical Sciences: Faculty Publications
Swelling subsequent to hyposmotic conditions activates a process of volume regulation present in most cell types. This volume adjustment is accomplished by osmolyte translocation toward the extracellular space to reach a new osmotic equilibrium. Molecules involved in this homeostatic mechanism have been broadly classified into two categories: organic and inorganic osmolytes. Inorganic osmolytes comprise mainly the intracellular ions K+ and Cl–. Cell swelling–induced activation of separate K+ and Cl– channels has been described in most preparations. Organic osmolytes are grouped in three categories: amino acids, polyalcohols, and methylamines. These osmolytes, particularly taurine, are present in …

Nearly all human immunodeficiency virus (HIV) infections are acquired mucosally, and the gut-associated lymphoid tissues are important sites for early virus replication. Thus, vaccine strategies designed to prime virus-specific cytotoxic T lymphocyte (CTL) responses that home to mucosal compartments may be particularly effective at preventing or containing HIV infection. The Salmonella type III secretion system has been shown to be an effective approach for stimulating mucosal CTL responses in mice. We therefore tested ∆phoP-phoQ attenuated strains of Salmonella enterica serovar Typhimurium and S. enterica serovar Typhi expressing fragments of the simian immunodeficiency virus (SIV) Gag protein fused to the …

The present invention provides a method to detect the presence of a microorganism or agent in an animal. The method encompasses placement of devices at various locations where the animal resides so as to induce the animal to initiate contact with the device. As a result of this contact, the animal deposits various microorganisms and agents on the device. The device is then tested for the presence of the particular microorganism or agent of interest.

The ability to regulate cell volume is an ancient conserved trait present in essentially all species through evolution. The maintenance of a constant cell volume is a homeostatic imperative in animal cells. Changes in cell water content affecting the concentration of intracellular messenger molecules impair the complex signaling network, crucial for cell functioning and intercellular communication. Although the renal homeostatic mechanisms exert a precise control of extracellular fluid osmolarity, this is challenged in a variety of pathological situations. The intracellular volume constancy is continuously compromised by the generation of local and transient osmotic microgradients, associated with nutrients uptake, secretion, cytoskeleton …

The cytochrome P450 (CYP) 2J2 arachidonic acid epoxygenase gene was down-regulated at a pre-translational level in human hepatoma-derived HepG2 cells incubated in a hypoxic environment; under these conditions, the expression of c-Jun and c-Fos mRNA and protein was increased. The 5′-upstream region of the CYP2J2 gene was isolated by amplification of a 2341 bp fragment and putative regulatory elements that resembled activator protein-1 (AP-1)-like sequences were identified. From transient transfection analysis, c-Jun was found to strongly activate a CYP2J2–luciferase reporter construct, but co-transfection with plasmids encoding c-Fos or c-Fos-related antigens, Fra-1 and -2, abrogated reporter activity. Using a series …

Nicotiana tabacum L. ‘Glurk’ plants were transformed with antiapoptotic animal genes [chicken Bcl-xl; nematode CED-9; chicken Bcl-xl(GA) a mutant of Bcl-xl; and a 3’ non-coding region of human Bcl-2, referred to as 161-1]. Our objectives were to determine whether plant transformation with anti-apoptotic genes ameliorates drought tolerance in tobacco plants by subjecting the plants to a dry-down period. The non-transformed Glurk and the transgenic Glurk harboring G115, which expresses β-glucuronidase, served as controls. Transformation of tobacco plants with animal anti-apoptotic genes significantly impacted the rates of photosynthesis (A) and stomatal conductance (gs), but not to the same extent …

Sox transcription factors play key regulatory roles throughout development, binding DNA through a consensus (A/T)(A/T)CAA(A/T)G sequence. Although many different Sox proteins bind to this se-quence, it has been observed that gene regulatory elements are commonly responsive to only a small subset of the entire family, implying that regulatory mechanisms exist to permit selective DNA bind-ing and/or transactivation by Sox family members. To identify and explore the mechanisms modu-lating gene activation by Sox proteins further, we compared the function of Sox-2 and Sox-11. This led to the discovery that Sox proteins are regulated differentially at multiple levels, including trans-activation, protein partnerships …

The Phycodnaviridae, Iridoviridae and related viruses, with diameters of 1500±2000 A Ê , are formed from large trigonal arrays of hexagonally close-packed capsomers forming the faces of icosahedra [Yan et al. (2000), Nature Struct. Biol. 7, 101-103; Nandhagopal et al. (2002), Proc. Natl Acad. Sci. USA, 99, 14758-14763]. Caspar and Klug predicted that such structures could be assembled from hexameric capsomers [Caspar & Klug (1962), Cold Spring Harbor. Symp. Quant. Biol. 27, 1-24], as was subsequently found in numerous icosahedral viruses. During the course of evolution, some viruses, including the virus families …

Adenovirus (Ad) precursor to the terminal protein (pTP) plays an essential roles in the viral DNA
replication. Ad pTP serves as a primer for the synthesis of a new DNA strand during the initiation
step of replication. In addition, Ad pTP forms organized spherical replication foci on the nuclear
matrix (NM) and anchors the viral genome to the NM. Here we identified the interferon inducible
gene product 1-8D (Inid) as a pTP binding protein by using a two-hybrid screen of a HeLa cDNA
library. Of the clones obtained in this assay, nine were identical to the Inid, a 13-kDa polypeptide …
