Unintended Fertility And The Stability Of Coresidential Relationships, Karen Guzzo, Sarah Hayford

Sociology Faculty Publications

Having an unintended birth is associated with maternal and child health outcomes, the mother-child relationship, and subsequent fertility. Unintended fertility likely also increases the risk of union dissolution for parents, but it is unclear whether this association derives from a causal effect or selection processes and whether it differs by union type. This article uses data from the 2002 National Survey of Family Growth to compare union stability after intended and unintended births in coresidential relationships. Results show that coresidential couples are more likely to break up after an unintended first or higher-order birth than after an intended first or …

Properties Of Lewis Lung Carcinoma Cells Surviving Curcumin Toxicity, Michael Eric Geusz, Dejun Yan

Biological Sciences Faculty Publications

The anti-inflammatory agent curcumin can selectively eliminate malignant rather than normal cells. The present study examined the effects of curcumin on the Lewis lung carcinoma (LLC) cell line and characterized a subpopulation surviving curcumin treatments. Cell density was measured after curcumin was applied at concentrations between 10 and 60 μM for 30 hours. Because of the high cell loss at 60 μM, this dose was chosen to select for surviving cells that were then used to establish a new cell line. The resulting line had approximately 20% slower growth than the original LLC cell line and based on ELISA contained …

Population Viability Analysis Of The Blue-Throated Macaw (Ara Glaucogularis) Using Individual-Based And Cohort-Based Pva Programs, Juan Luis Bouzat, Rosa I. Strem

Biological Sciences Faculty Publications

We developed a demographic model to perform a population viability analysis (PVA) of the Blue-throated Macaw (Ara glaucogularis), a critically endangered species endemic to Bolivia. PVA simulations were run using individual based (VORTEX 9.72) and cohort-based (RAMAS GIS 4.0) programs. A baseline simulation allowed for the assessment of the status of the species based on estimates of extinction risk and population declines under current conditions of abundance and habitat availability. The role of multiple demographic, environmental, and anthropogenic parameters was evaluated to assess changes affecting population declines and extinction risk. The baseline simulation showed that the Blue-throated Macaw has a …

Unraveling The Determinants Of Protrusion Formation, Mita Varghese, Peter Gorsevski, Marilyn L. Cayer, Nancy S. Boudreau, Carol A. Heckman

Biological Sciences Faculty Publications

A computerized morphometric classification technique based on latent factors reveals major protrusion classes: factors 4, 5, and 7. Previous work showed that factor 4 represented filopodia, 5 the distribution of lamellar cytoplasm, and 7 a blunt protrusion. We explore the relationship of focal contact (FC) characteristics and their integrated actin cables to factors values. The results show that FC maturation/cytoskeletal integration affects factor 5, because FC elongation/integration was correlated with its values. On the contrary, 7 values decreased with maturation, so cable or FC size or their integration must be restricted to form these protrusions. Where integration did occur, the …

Extraction Of Dna From Plant And Fungus Tissues In Situ, Scott O. Rogers, Amal S. Abu Almakarem, Katie L. Heilman, Heather L. Conger, Yury M. Shtarkman

Biological Sciences Faculty Publications

Background: When samples are collected in the field and transported to the lab, degradation of the nucleic acids contained in the samples is frequently observed. Immediate extraction and precipitation of the nucleic acids reduces degradation to a minimum, thus preserving accurate sequence information. An extraction method to obtain high quality DNA in field studies is described. Findings. DNA extracted immediately after sampling was compared to DNA extracted after allowing the sampled tissues to air dry at 21°C for 48 or 72 hours. While DNA extracted from fresh tissues exhibited little degradation, DNA extracted from all tissues exposed to 21°C air …

Plasticity Of Total And Intracellular Phosphorus Quotas In Microcystis Aeruginosa Cultures And Lake Erie Algal Assemblages, Robert Michael Mckay, Matthew A. Saxton, Robert J. Arnold, Richard A. Bourbonniere, Steven W. Wilhelm

Biological Sciences Faculty Publications

Blooms of the potentially toxic cyanobacterium Microcystis are common events globally, and as a result significant resources continue to be dedicated to monitoring and controlling these events. Recent studies have shown that a significant proportion of total cell-associated phosphorus (P) in marine phytoplankton can be surface adsorbed; as a result studies completed to date do not accurately report the P demands of these organisms. In this study we measure the total cell-associated and intracellular P as well as growth rates of two toxic strains of Microcystis aeruginosa Kütz grown under a range of P concentrations. The results show that the …

An Evaluation Of The Role Of Sensory Drive In The Evolution Of Lake Malawi Cichlid Fishes, Adam R. Smith, Moira J. Van Staaden, Karen L. Carleton

Biological Sciences Faculty Publications

Although the cichlids of Lake Malawi are an important model system for the study of sensory evolution and sexual selection, the evolutionary processes linking these two phenomena remain unclear. Prior works have proposed that evolutionary divergence is driven by sensory drive, particularly as it applies to the visual system.While evidence suggests that sensory drive has played a role in the speciation of Lake Victoria cichlids, the findings fromseveral lines of research on cichlids of LakeMalawi are not consistent with the primary tenets of this hypothesis. More specifically, three observations make the sensory drive model implausible in Malawi: (i) a lack …

Templated Synthesis Of Glycoluril Hexamer And Monofunctionalized Cucurbit[6]Uril Derivatives, Derick Lucas, Tsuyoshi Minami, Greg Iannuzzi, Liping Cao, James B. Wittenberg, Pavel Anzenbacher Jr., Lyle Isaacs

Chemistry Faculty Publications

We report that the p-xylylenediammonium ion (11) acts as a template in the cucurbit[n]uril forming reaction that biases the reaction toward the production of methylene bridged glycoluril hexamer (6C) and bis-nor-seco-CB [10]. Hexamer 6C is readily available on the gram scale by a one step synthetic procedure that avoids chromatography. Hexamer 6C undergoes macrocylization. with (substituted) phthalaldehydes 12,14,.15, and 18-in 9 M H2SO4 or concd HCl at room temperature to deliver monofunctionalized CB[6] derivatives 13,16,17, and 19 that are poised for further functionalization reactions: The kinetics of the macrocyclization reaction between hexamer and formaldehyde or phthalaldehyde depends on the presence …

The Impact Of An Aquatic Exercise Protocol On Physiologic Measures Within An Asthmatic Population, Kasee Hildenbrand, Timothy S. Freson, Celestina Barbosa-Leiker, Sara Nordio, Bruce E. Becker, Ashley J. Miller

International Journal of Aquatic Research and Education

Individuals suffering from asthma typically have subnormal exercise tolerance and poor physical fitness. The purpose of this case series study was to examine the impact of a new aquatic exercise protocol on physiological variables in a group of asthmatics. Participants were medically diagnosed and managed asthmatics in a rural community. A total of 8 males and 12 females were accepted into the study with 7 males and 9 females completing the 12-week study. Physiological measures were taken pre- and posttreatment with paired t-tests used for analyses. Increases in VO2max (pre-treatment mean (M) = 31.244 SD = 9.772; post-treatment M = …

Responses Of Swimmers Caught In Rip Currents: Perspectives On Mitigating The Global Rip Current Hazard, Robert W. Brander, Anthony Bradstreet, Shauna Sherker, Jamie Macmahan

International Journal of Aquatic Research and Education

Rip currents are the primary mechanism on many of the world’s beaches associated with rescues and drownings and have long been the focus of beachgoer education and awareness strategies. Traditional approaches to mitigating the rip current hazard typically provide information on escape procedures for beachgoers caught in a rip current. Several of these approaches are now being challenged by new scientific findings leading to uncertainty and debate amongst scientists and beach safety practitioners. This paper suggests that future research efforts on mitigating the rip current hazard should focus on quantifying the physical and behavioral responses of beachgoers who have been …

River Drying Lowers The Diversity And Alters The Composition Of An Assemblage Of Desert Riparian Arthropods, Kevin E. Mccluney, John L. Sabo

Biological Sciences Faculty Publications

Summary 1. Many studies have shown negative effects of river drying on in‐stream animals. However, the influence of river drying on riparian animals remains poorly studied. We examined ground‐dwelling riparian arthropod assemblages along a drying section of the semi‐arid San Pedro River in southeastern Arizona, U.S.A.

2. We found strong differences in assemblage composition, taxon diversity and the abundance of key taxa between dry and flowing sites, with higher diversity and abundance of most taxa at flowing sites.

3. Changes in assemblage composition, taxon diversity and abundance of representative taxa were associated with a combined measure of water availability that …

Death Of The Tonb Shuttle Hypothesis, Ray A. Larsen, Michael G. Gresock, Marina I. Savenkova, Anne A. Ollis, Kathleen Postle

Biological Sciences Faculty Publications

A complex of ExbB, ExbD, andTonB couples cytoplasmic membrane (CM) proton motive force (pmf) to the active transport of large, scarce, or important nutrients across the outer membrane (OM). TonB interacts with OM transporters to enable ligand transport. Several mechanical models and a shuttle model explain how TonB might work. In the mechanical models, TonB remains attached to the CM during energy transduction, while in the shuttle model theTonB N terminus leaves the CM to deliver conformationally stored potential energy to OM transporters. Previous studies suggested thatTonB did not shuttle based on the activity of a GFP-TonB fusion that was …

Probing Single-Molecule Enzyme Active-Site Conformational State Intermittent Coherence, Yufan He, Yue Li, Saptarshi Mukherjee, Yan Wu, Honggao Yan, H. Peter Lu

Chemistry Faculty Publications

The relationship between protein conformational dynamics and enzymatic reactions has been a fundamental focus in modern enzymology. Using single-molecule fluorescence resonance energy transfer (FRET) with a combined statistical data analysis approach, we have identified the intermittently appearing coherence of the enzymatic conformational state from the recorded single-molecule intensity-time trajectories of enzyme 6-hydroxymethyl-7,8-dihydropterin pyrophosphokinase (HPPK) in catalytic reaction. The coherent conformational state dynamics suggests that the enzymatic catalysis involves a multistep conformational motion along the coordinates of substrate-enzyme complex formation and product releasing, presenting as an extreme dynamic behavior intrinsically related to the time bunching effect that we have reported previously. …
