Characterization Of Ips Pini Ipsdienol Dehydrogenase (Idol Dh), Heidi Pak, Claus Tittiger, William Welch

Festival of Communities: UG Symposium (Posters)

Ipsdienol is an important pheromone component for pine engraver beetle, Ips pini. Ipsdienol is a ten carbon monoterpenoid secondary alcohol and ipsdienone is the corresponding ketone. We are characterizing the activity of recombinant IDOL DH produced in Sf9 (insect) cells. The enzyme has a high stereospecificity: (-) ipsdienol was found to be a substrate while (+)-ipsdienol was neither a substrate nor inhibitor. Closely related monoterpenoids, such as nerol, geraniol, and citral, were neither substrates nor inhibitors. Smaller compounds, such as 2-propanol, also failed to act as an inhibitor or substrate. This indicates the binding site of this enzyme is highly …

Does Thermal Stress Cause Females Of The Plant Bryum Argenteum To Manipulate The Sex Ratios Of Their Offspring?, Elisha Rhodes, Lloyd Stark

Festival of Communities: UG Symposium (Posters)

About half of all moss taxa exhibit female-biased sex ratios, and bryophyte male rarity remains largely unexplained. One possible explanation is differential stress tolerance of spores due to maternal sporophyte manipulation during stress. To test this hypothesis, sporophytes of the species Bryum argenteum were subjected to thermal stress and observed for growth abnormalities and sporophyte abortions. Data display a correlation between increased temperature and increased sporophyte abortions as well as increased time to complete meiosis, possibly indicating decreased fitness. Continued global warming may create more stressful environments for sporophytes resulting in the elimination of males from local populations.

Effect Of Temperature And Oxygen Levels On Lactate Production In Palaemonetes Pugio, Robin Schofield, Teresa Mika, Carl Reiber

Festival of Communities: UG Symposium (Posters)

Oxygen delivery rates must keep pace with the increased metabolic rate observed in poikilothermic animals exposed to increased temperature if aerobic metabolism is to be maintained. Physical failure of the oxygen delivery system to meet these demands may be a mechanism of cardiac failure in crustaceans at temperature extremes. As part of the determination of the effect of temperature on the cardio-respiratory system, we are measuring whole animal lactate levels in grass shrimp acclimated to 20°C over temperature ranges in normoxic and hyperoxic conditions. Lactate levels are measured as an indicator of a switch from aerobic to anaerobic metabolism. Animals …

Serpentinite Weathering And Implications For Mars, Valerie Tu, Julie Baumeister, Rodney Metcalf, A. Olsen, Elisabeth Hausrath

Festival of Communities: UG Symposium (Posters)

In the search for life on Mars near-surface soil environments may be important habitats for life accessible to future missions. Serpentinite rocks have been documented on Mars, as well as other clay minerals including smectite and kaolinites. Previous studies of soils formed on serpentinites on Earth have documented the formation of extensive clays. Serpentinites are additionally of interest as habitats for life such as methanogens. Here we examine weathering of serpentinites from bedrock to soil surface, as a potential route for the formation of clay minerals on Mars from abundant ultramafic minerals. We additionally test for the presence of Fe-oxidizing …

Stationary Phase Mutagenesis In Bacillus Subtilisis Independent Of Genome Replication, Mark Upchurch, Holly Martin, Eduardo Robleto

Festival of Communities: UG Symposium (Posters)

Stationary phase mutagenesis is defined as cellular mechanisms that produce genetic diversity in cells experiencing conditions of stress. These processes are associated with many biological phenomena, including those that produce the formation of cancers in animal cells and other degenerative diseases. Also, these mechanisms are associated with the accumulation of beneficial mutations in bacteria, but follow stochastic processes and are controlled by genetic factors. The current models explaining the generation of stress-induced mutations are predicated on the formation of DNA replication intermediates that are formed during the repair of damaged DNA or during DNA replication and transcription encounters. Here we …

Molecular, Cellular & Biomedical Sciences

Bacteria of the genus Frankia are mycelium-forming actinomycetes that are found as nitrogen-fixing facultative symbionts of actinorhizal plants. Although soil-dwelling actinomycetes are well-known producers of bioactive compounds, the genus Frankia has largely gone uninvestigated for this potential. Bioinformatic analysis of the genome sequences of Frankia strains ACN14a, CcI3, and EAN1pec revealed an unexpected number of secondary metabolic biosynthesis gene clusters. Our analysis led to the identification of at least 65 biosynthetic gene clusters, the vast majority of which appear to be unique and for which products have not been observed or characterized. More than 25 secondary metabolite structures or structure …

Chemistry & Biochemistry Faculty Works

The asymmetric unit of the title crystal, [FeCl2(C3H9P)3(CO)]·[FeCl2(C3H9P)2(CO)2]·2C4H8O, contains half mol­ecules of the two closely related FeII complexes lying on mirror planes and a tetra­hydro­furan solvent mol­ecule, one C atom of which is disordered over two sets of sites with site occupancy factors 0.633 (9) and 0.367 (9). In both FeII complex mol­ecules, a distorted octa­hedral coordination geometry has been observed around the Fe atoms. Weak intermolecular C-H...O inter­actions are observed in the crystal structure.

Phosphatidic Acid Binds And Stimulates Arabidopsis Sphingosine Kinases, Xuemin Wang, Liang Guo, Girish Mishra, Kyle Taylor

Biology Department Faculty Works

Phosphatidic acid (PA) and phytosphingosine-1-phosphate (phyto-S1P) have both been identified as lipid messengers mediating plant response to abscisic acid (ABA). To determine the relationship of these messengers, we investigated the direct interaction of PA with Arabidopsis sphingosine kinases (SPHKs) that phosphorylate phytosphingosine to generate phyto-S1P. Two unique SPHK cDNAs were cloned from the annotated At4g21540 locus of Arabidopsis, and the two transcripts are differentially expressed in Arabidopsis tissues. Both SPHKs are catalytically active, phosphorylating various longchain sphingoid bases (LCBs) and are associated with the tonoplast. They both interact with PA as demonstrated by lipid-filter binding, liposome binding, and surface plasmon …

Purkinje Cell Association With Microglia/Macrophages In Degenerating Cerebellum Of Multiple System Atrophy Patients, Ashley A. Mckinney

Research and Creative Activities Poster Day

Multiple system atrophy (MSA) is a sporadic neurodegenerative disease with unknown etiology, involving Parkinson's disease, Autonomic Failure, and Olivopontocerebellar Atrophy (OPCA). To define a possible relationship between phagocytic immune cells and loss of Purkinje cells in MSA/OPCA, we measured the incidence of microglial/macrophages in close association with Purkinje cells and/or their axons and dendrites. Using immunocytochemistry methods on cerebellar sections from MSA and control brains from the New York Brain Bank at Columbia University, we identified Purkinje cells and their processes using anti-calbindin, and microglia/macrophages using anti-CD68. Calbindin labeled Purkinje cell body, axon, and dendritic profiles were counted in the …

Use Of Peak Decay Analysis And Affinity Microcolumns Containing Silica Monoliths For Rapid Determination Of Drug-Protein Dissociation Rates, Michelle J. Yoo, David S. Hage

David Hage Publications

This report examined the use of silica monoliths in affinity microcolumns containing human serum albumin (HSA) to measure the dissociation rates for various drugs from this protein. Immobilized HSA and control monolith columns with dimensions of 1 mm × 4.6 mm i.d. were prepared for this work and used with a noncompetitive peak decay method. Several drugs known to bind HSA were examined, such as warfarin, diazepam, imipramine, acetohexamide, and tolbutamide. Items that were studied and optimized in this method included the sample volume, sample concentration, and elution flow rate. It was found that flow rates up to 10 mL/min …

Kinetic Studies Of Drug-Protein Interactions By Using Peak Profiling And High-Performance Affinity Chromatography: Examination Of Multi-Site Interactions Of Drugs With Human Serum Albumin Columns, Zenghan Tong, John E. Schiel, Efthimia Papastavros, Corey M. Ohnmacht, Quentin R. Smith, David S. Hage

David Hage Publications

Carbamazepine and imipramine are drugs that have significant binding to human serum albumin (HSA), the most abundant serum protein in blood and a common transport protein for many drugs in the body. Information on the kinetics of these drug interactions with HSA would be valuable in understanding the pharmacokinetic behavior of these drugs and could provide data that might lead to the creation of improved assays for these analytes in biological samples. In this report, an approach based on peak profiling was used with high-performance affinity chromatography to measure the dissociation rate constants for carbamazepine and imipramine with HSA.

The Model Seed Plug-In For Viewing And Editing Metabolic Models, Benjamin Bockstege, Nicholas Hazekamp

10th Annual Celebration of Undergraduate Research and Creative Performance (2011)

The goal of our research is to develop a plug-in for Cytoscape that will be used in tandem with the Model SEED Viewer to help biologists better understand and visualize the metabolic pathways of bacteria. The Model SEED is an online resource at www.theseed.org/models that provides biologists with a static but very detailed view of metabolic models. It uses KEGG (www.genome.jp) metabolic pathway maps which cannot be edited by users. This ability to edit metabolic pathways is one of our primary focuses in creating the plug-in – in particular, adding, removing, and moving reaction and compound nodes. Additionally, we want …

Effects Of Population Dynamics And Competition On Parental Investment In Eastern Bluebirds (Sialia Sialis), Nickolas Davros, Jennifer Laroche

10th Annual Celebration of Undergraduate Research and Creative Performance (2011)

Parental investment and competition are two important elements of life history strategies affecting reproductive success. The effect of parental investment on reproductive success in a west Michigan population of Eastern Bluebirds (Sialia sialis) was investigated, including parameters such as feeding rates, sex of parent, type and size of items delivered to chicks, number of chicks, and age of chicks. We found all measures of parental investment related to provisioning of nestlings to be indistinguishable within mated pairs. We also determined that significantly more food was brought when parents had a large brood (3+ chicks) as compared with a small brood …

Rediscovery Of Cicindela Scabrosa Floridana Cartwright (Coleoptera: Cicindelidae) And Its Elevation To Species Level, David Brzoska, C. Barry Knisley, Jeffrey Slotten

Insecta Mundi

First discovered in 1934 and described as a variety of Cicindela abdominalis Fabricius (Coleoptera: Cicindelidae), the form floridana, to our knowledge, has not been recollected until we discovered it in 2007, south of the presumed type locality. From our examination of the type specimen, eight paratypes and 40 specimens from the new locality and additional study, we reinterpreted its status to be a full species. This interpretation is based on distinctive and consistent differences from the closely related Cicindelidia scabrosa (Schaupp). These differences include morphology (maculation, color and elytral microsculpture), distribution, habitat, and seasonality. We present here a more …
