Temporal Dynamics Of Soil Carbon And Nitrogen Resources Within A Grassland-Creosote Ecotone At The Sevilleta National Wildlife Refuge, New Mexico (1992-1994), Carleton White, Thomas L. Kieft

Sevilleta LTER Program Data

Plant communities across large portions of the southwestern United States have shifted from grassland to desert shrubland. Studies have demonstrated that soil nutrient resources become spatially more heterogeneous and are redistributed into islands of fertility with this shift in vegetation. This research addressed the additional question of whether soil resources become more temporally heterogeneous along a grassland-shrubland ecotome. Within adjacent grassland and creosotebush sites, soil profiles were described at 3 pits and samples collected for description of nutrient resources within the profile. Relative cover of plant species and bare soil were determined within each site by line transects. The top …

Effects Of Kangaroo Rats On Plant Species Dominance In A Chihuahuan Desert Grassland At The Sevilleta National Wildlife Refuge, New Mexico (1988), Debra Peters, Scott Collins

Sevilleta LTER Program Data

Our objective was to evaluate the effects of burrowing activities by banner-tail kangaroo rats (Dipodomys spectabilis Merriam) on plant community structure and species dominance for two patch types at an ecotone between shortgrass steppe and desert grasslands in New Mexico, USA. Ten mounds produced by kangaroo rats were selected in patches dominated by Bouteloua gracilis (the dominant in shortgrass steppe communities) and ten mounds were selected in patches dominated by Bouteloua eriopoda (the dominant in Chihuahuan desert grasslands). Plant cover and density by species were sampled from three locations associated with each mound: the mound proper, the edge of the …

Materials For Pharmaceutical Dosage Forms: Molecular Pharmaceutics And Controlled Release Drug Delivery Aspects, Heidi M. Mansour, Minji Sohn, Abeer Al-Ghananeem, Patrick P. Deluca

Pharmaceutical Sciences Faculty Publications

Controlled release delivery is available for many routes of administration and offers many advantages (as microparticles and nanoparticles) over immediate release delivery. These advantages include reduced dosing frequency, better therapeutic control, fewer side effects, and, consequently, these dosage forms are well accepted by patients. Advances in polymer material science, particle engineering design, manufacture, and nanotechnology have led the way to the introduction of several marketed controlled release products and several more are in pre-clinical and clinical development.

Sialic Acid Transport And Catabolism Are Cooperatively Regulated By Siar And Crp In Nontypeable Haemophilus Influenzae, Jason W. Johnston, Haider Shamsulddin, Anne-Frances Miller, Michael A. Apicella

Microbiology, Immunology, and Molecular Genetics Faculty Publications

BACKGROUND: The transport and catabolism of sialic acid, a critical virulence factor for nontypeable Haemophilus influenzae, is regulated by two transcription factors, SiaR and CRP.

RESULTS: Using a mutagenesis approach, glucosamine-6-phosphate (GlcN-6P) was identified as a co-activator for SiaR. Evidence for the cooperative regulation of both the sialic acid catabolic and transport operons suggested that cooperativity between SiaR and CRP is required for regulation. cAMP was unable to influence the expression of the catabolic operon in the absence of SiaR but was able to induce catabolic operon expression when both SiaR and GlcN-6P were present. Alteration of helical phasing supported …

New Views On Strand Asymmetry In Insect Mitochondrial Genomes, Shu-Jun Wei, Min Shi, Xue-Xin Chen, Michael J. Sharkey, Cornelis Van Achterberg, Gong-Yin Ye, Jun-Hua He

Entomology Faculty Publications

Strand asymmetry in nucleotide composition is a remarkable feature of animal mitochondrial genomes. Understanding the mutation processes that shape strand asymmetry is essential for comprehensive knowledge of genome evolution, demographical population history and accurate phylogenetic inference. Previous studies found that the relative contributions of different substitution types to strand asymmetry are associated with replication alone or both replication and transcription. However, the relative contributions of replication and transcription to strand asymmetry remain unclear. Here we conducted a broad survey of strand asymmetry across 120 insect mitochondrial genomes, with special reference to the correlation between the signs of skew values and …

Cardiovascular Risk Associated With Interactions Among Polymorphisms In Genes From The Renin-Angiotensin, Bradykinin, And Fibrinolytic Systems, John P. Bentley, Folkert W. Asselbergs, Christopher S. Coffey, Patricia R. Hebert, Jason H. Moore, Hans L. Hillege, Wiek H. Van Gilst

Dartmouth Scholarship

Background: Vascular fibrinolytic balance is maintained primarily by interplay of tissue plasminogen activator (t-PA) and plasminogen activator inhibitor type 1 (PAI-1). Previous research has shown that polymorphisms in genes from the renin- angiotensin (RA), bradykinin, and fibrinolytic systems affect plasma concentrations of both t-PA and PAI-1 through a set of gene-gene interactions. In the present study, we extend this finding by exploring the effects of polymorphisms in genes from these systems on incident cardiovascular disease, explicitly examining two-way interactions in a large population- based study.

Specificity Determinants Of Arma, A Ribosomal Rna Methyltransferase That Confers Antibiotic Resistance, Tamara Zarubica

Theses and Dissertations

Bacterial resistance to 4,6-type aminoglycoside antibiotics, which target the 30S ribosomal subunit, has been traced to the arm/rmt family of rRNA methyltransferases. These plasmid-encoded enzymes transfer a methyl group from S-adenosylmethionine to N7 of the buried G1405 in the aminoglycoside binding site of 16S rRNA in the 30S ribosomal subunit. Neither 16S rRNA alone nor intact 70S ribosome is an efficient substrate for armA methyltransferase. To more fully characterize this family of enzymes, xiii we have investigated the substrate requirements of ArmA. We determined the Mg2+ dependence of ArmA activity and found that the enzyme could recognize both translationally active …

Prolonged Space Flight-Induced Alterations In The Structure And Function Of Human Skeletal Muscle Fibres, Robert H. Fitts, S. W. Trappe, David R. Costill, Philip M. Gallagher, Andrew C. Creer, Patricia A. Colloton, Jim R. Peters, Janell Romatowski, J. L. Bain, Danny A. Riley

Biological Sciences Faculty Research and Publications

The primary goal of this study was to determine the effects of prolonged space flight (~180 days) on the structure and function of slow and fast fibres in human skeletal muscle. Biopsies were obtained from the gastrocnemius and soleus muscles of nine International Space Station crew members ~45 days pre- and on landing day (R+0) postflight. The main findings were that prolonged weightlessness produced substantial loss of fibre mass, force, and power with the hierarchy of the effects being soleus type I > soleus type II > gastrocnemius type I > gastrocnemius type II. Structurally, the quantitatively most important adaptation was fibre atrophy …

Learning Styles: Learning That Empowers Students?, Tofi Rahal

All Works

Despite much disagreement, educators and psychologists agree that different students learn differently. Learning differences come under many labels, such as 'learning styles', 'thinking styles', 'personality types' or 'multiple intelligences'. This paper supports the use of learning style models as a theoretical framework for quality educational development in the Arab Gulf Countries. It will (a) briefly explore various learning styles models, with primary focus on the Dunn & Dunn model and its assessment instruments; (b) review key research conducted internationally, as well as locally at Zayed University; (c) examine the benefits of using multimodal and multisensory instructional packages in various disciplines; …

Morphological Analysis Based On A Fractional Dynamic Model For Hyphal Growth, Jonathan Blackledge, Dan Barry

Conference papers

The development of methods capable of accurately characterising the morphology of filamentous microbes represents a significant challenge to biotechnologists. This is because the productivity of many industrial fermentation processes is heavily dependent on the morphological form adopted by an organism. It is therefore of significant value if a quantitative model and associated metric(s) for morphological forms determined by complex phenotypes can be determined non-invasively, e.g. through image analysis. Specific interest is in the quantification of the branching behaviour of an organism. This is due to the link between branching frequency, biomass and metabolite production. In this paper we present a …

Repression Of Wnt Signaling By A Fer-Type Nonreceptor Tyrosine Kinase, Aaron P. Putzke, Joel H. Rothman

Faculty Publications

The Wnt signaling pathway must be properly modulated to ensure an appropriate output: pathological conditions result from either insufficient or excessive levels of Wnt signal. For example, hyperactivation of the Wnt pathway is associated with various cancers and subnormal Wnt signaling can lead to increased invasiveness of tumor cells. We found that the Caenorhabditis elegans ortholog of the Fer nonreceptor tyrosine kinase, FRK-1, limits Wnt signaling by preventing the adhesion complex-associated beta-catenin, HMP-2, from participating in Wnt-dependent specification of the endoderm during embryogenesis. Removal of FRK-1 function results in relocalization of HMP-2 to the nucleus of epidermal cells, and allows …

The Relationship Between Pretend Play And Cognitive, Linguistic, And Social Skills Development In Early Childhood : A Project Based Upon Secondary Analysis Of Developmental Screening Data From An Elementary School In Plainfield, Connecticut, Lauren Ann Sebastianelli

Theses, Dissertations, and Projects

There is substantial research to support the positive correlation between pretend play and cognitive, language and social skills development in early childhood. Most of this research has explored bivariate relationships. We know little about how these variables might co-vary in the same sample. This exploratory study was based on secondary analysis of developmental screening data for a preschool program in Connecticut. The sample was comprised of 79 three and four year-olds. Proxies for pretend play and cognitive, language and social skills development were operationalized from a standardized instrument, Developmental Indicators for the Assessment of Learning (DIAL) and a Social Skills …

Negative Effects Of Paternal Age On Children's Neurocognitive Outcomes Can Be Explained By Maternal Education And Number Of Siblings, Ryan D. Edwards, Jennifer Roff

Publications and Research

Background Recent findings suggest advanced paternal age may be associated with impaired child outcomes, in particular, neurocognitive skills. Such patterns are worrisome given relatively universal trends in advanced countries toward delayed nuptiality and fertility. But nature and nurture are both important for child outcomes, and it is important to control for both when drawing inferences about either pathway.

Methods and Findings We examined cross-sectional patterns in six developmental outcome measures among children in the U.S. Collaborative Perinatal Project (n=31,346). Many of these outcomes at 8 mo, 4 y, and 7 y of age (Bayley scales, Stanford Binet Intelligence Scale, Graham-Ernhart …

Marker Free Transgenic Plants: Engineering The Chloroplast Genome Without The Use Of Antibiotic Selection, Henry Daniell

UCF Patents

The present invention provides for a method to circumvent the problem of using antibiotic resistant selectable markers. In particular, target plants are transformed using a plastid vector which contains heterologous DNA sequences coding for a phytotoxin detoxifying enzyme or protein. The selection process involves converting a antibiotic-free phytotoxic agent by the expressed phytotoxin detoxifying enzyme or protein to yield a nontoxic compound. The invention provides for various methods to use antibiotic-free selection in chloroplast transformation.

Developing A Conceptual Model Of Virtual Organizations For Citizen Science, Andrea Wiggins, Kevin Crowston

Information Systems and Quantitative Analysis Faculty Publications

This paper develops an organisation design-oriented conceptual model of scientific knowledge production through citizen science virtual organisations. Citizen science is a form of organisation design for collaborative scientific research involving scientists and volunteers, for which internet-based modes of participation enable massive virtual collaboration by thousands of members of the public. The conceptual model provides an example of a theory development process and discusses its application to an exploratory study. The paper contributes a multi-level process model for organising investigation into the impact of design on this form of scientific knowledge production.
