Arrays of continuous flow thermal reactors were designed, configured, and fabricated in a 96-device (12 × 8) titer-plate format with overall dimensions of 120 mm × 96 mm, with each reactor confined to a 8 mm × 8 mm footprint. To demonstrate the potential, individual 20-cycle (740 nl) and 25-cycle (990 nl) reactors were used to perform the continuous flow polymerase chain reaction (CFPCR) for amplification of DNA fragments of different lengths. Since thermal isolation of the required temperature zones was essential for optimal biochemical reactions, three finite element models, executed with ANSYS (v. 11.0, Canonsburg, PA), were used to …

Template-free controlled aggregation and spectral properties in fluorescent organic nanoparticles (FONs) is highly desirable for various applications. Herein, we report a nontemplated method for controlling the aggregation in near-infrared (NIR) cyanine-based nanoparticles derived from a group of uniform materials based on organic salts (GUMBOS). Cationic heptamethine cyanine dye 1,1′,3,3,3′,3′-hexamethylindotricarbocyanine (HMT) was coupled with five different anions, viz., [NTf2-], [BETI -], [TFPB-], [AOT-], and [TFP4B-], by an ion-exchange method to obtain the respective GUMBOS. The nanoGUMBOS obtained via a reprecipitation method were primarily amorphous and spherical (30-100 nm) as suggested by selected area electron diffraction (SAED) and transmission electron microscopy (TEM). …

Simple mass balance models are applied to a high resolution 234Th profile from the northwest Pacific to examine the magnitude, rate, and depth distribution of particle remineralization processes below the euphotic zone (Ez). Here, excess 234Th (234Th > 238U) below the Ez is attributed to fragmentation processes that result in the conversion of sinking to non-sinking particles. By considering particulate organic carbon (POC) to 234Th ratios on particles, we show that POC flux attenuation is larger than for 234Th, which we attribute to bacterial and zooplankton consumption of sinking POC. Three case studies are …

Faculty Publications
The reaction of 5,10,15-tritolylcorrole with EtMgBr opens the way for novel functionalizations of the corrole ring. DDQ oxidation of the macrocycle, followed by addition of the Grignard reagent, led to the formation of 5- and 10-alkyl substituted isocorroles in satisfying yields. Together with the one-pot formation of these isocorrole isomers, the use of such a nucleophile evidenced the competitive reactivity of the macrocycle β-positions, leading to the formation of 2-bromo- and 3-bromo-5,10,15-tritolylcorrole. While the formation of these monobromocorrole derivatives is not unprecedented, this is the first time the isomers have been separated and fully characterized. Furthermore, the higher yields of …

Effect Of Overall Charge And Charge Distribution On Cellular Uptake, Distribution And Phototoxicity Of Cationic Porphyrins In Hep2 Cells, Timothy J. Jensen, M. Graça H. Vicente, Raymond Luguya, Jolanna Norton, Frank R. Fronczek, Kevin M. Smith
Faculty Publications
Five cationic porphyrins bearing one to four -N(CH3)3+ groups linked to the p-phenyl positions of 5,10,15,20-tetraphenylporphyrin (TPP) were synthesized in order to study the effect of overall charge and its distribution on the cellular uptake, phototoxicity and intracellular localization using human carcinoma HEp2 cells. The di-cationic porphyrins DADP-o and DADP-a accumulated the most within cells and preferentially localize within vesicular compartments and in mitochondria. Of these two only DADP-a was phototoxic to the cells (IC50=3μM at 1J/cm2). The mono-cationic porphyrin MAP was found to be the most phototoxic of the series, and it localized mainly in lipid membranes, including the …

In species whose evolutionary history has provided natural tolerance to dehydration and freezing, metabolic depression is often a pre-requisite for survival. We tested the hypothesis that preconditioning of mammalian cells with 5-aminoimidazole-4-carboxamide-1-b-d-ribofuranoside (AICAR) to achieve metabolic depression will promote greater survivorship during cryopreservation. AICAR is used extensively to stimulate AMP-activated protein kinase (AMPK), which can result in downregulation of biosynthetic processes. We showed that the metabolic interconversion of AICAR was cell-type dependent. Accumulation of 5-aminoimidazole-4-carboxamide-1b-d-ribofuranosyl-5'-monophosphate (ZMP), as well as other metabolites that possess multiple phosphates (i.e., ZDP, ZTP), varied approximately 3.5-fold across the cell lines tested. AICAR treatment also significantly …
A Mobile Threat To Genome Stability: The Impact Of Non-Ltr Retrotransposons Upon The Human Genome, Miriam K. Konkel, Mark A. Batzer
A Mobile Threat To Genome Stability: The Impact Of Non-Ltr Retrotransposons Upon The Human Genome, Miriam K. Konkel, Mark A. Batzer
Faculty Publications
It is now commonly agreed that the human genome is not the stable entity originally presumed. Deletions, duplications, inversions, and insertions are common, and contribute significantly to genomic structural variations (SVs). Their collective impact generates much of the inter-individual genomic diversity observed among humans. Not only do these variations change the structure of the genome; they may also have functional implications, e.g. altered gene expression. Some SVs have been identified as the cause of genetic disorders, including cancer predisposition. Cancer cells are notorious for their genomic instability, and often show genomic rearrangements at the microscopic and submicroscopic level to which …

Cryptotanshinone (CPT), a natural compound isolated from the plant Salvia miltiorrhiza Bunge, is a potential anticancer agent. However, little is known about its anticancer mechanism. Here, we show that CPT inhibited cancer cell proliferation by arresting cells in G1-G0 phase of the cell cycle. This is associated with the inhibition of cyclin D1 expression and retinoblastoma (Rb) protein phosphorylation. Furthermore, we found that CPT inhibited the signaling pathway of the mammalian target of rapamycin (mTOR), a central regulator of cell proliferation. This is evidenced by the findings that CPT inhibited type I insulin-like growth factor I- or 10% fetal bovine …

Emerging evidence suggests that increases in activated T cell populations in adipose tissue may contribute toward obesity-associated metabolic syndrome. The present study investigates three unanswered questions: 1) Do adipose-resident T cells (ARTs) from lean and obese mice have altered cytokine production in response to TCR ligation?; 2) Do the extralymphoid ARTs possess a unique TCR repertoire compared with lymphoid-resident T cells and whether obesity alters the TCR diversity in specific adipose depots?; and 3) Does short-term elimination of T cells in epididymal fat pad without disturbing the systemic T cell homeostasis regulate inflammation and insulin-action during obesity? We found that …

Faculty Publications
The monk parakeet (Myiopsitta monachus) is a successful invasive species that does not exhibit life history traits typically associated with colonizing species (e.g., high reproductive rate or long-distance dispersal capacity). To investigate this apparent paradox, we examined individual and population genetic patterns of microsatellite loci at one native and two invasive sites. More specifically, we aimed at evaluating the role of propagule pressure, sexual monogamy and long-distance dispersal in monk parakeet invasion success. Our results indicate little loss of genetic variation at invasive sites relative to the native site. We also found strong evidence for sexual monogamy from patterns of …

Elevated atmospheric CO2 can cause increased carbon fixation and altered foliar chemical composition in a variety of plants, which has the potential to impact forested headwater streams because they are detritus-based ecosystems that rely on leaf litter as their primary source of organic carbon. Fungi and bacteria play key roles in the entry of terrestrial carbon into aquatic food webs, as they decompose leaf litter and serve as a source of nutrition for invertebrate consumers. This study tested the hypothesis that changes in leaf chemistry caused by elevated atmospheric CO2 would result in changes in the size and …

We tested the hypothesis that risk of early mortality from cancers of the digestive system will be greater in men with, compared to men without, the metabolic syndrome (MetS). Participants were 33,230 men who were seen at the Cooper Clinic in Dallas, Texas and followed for 14.4 (SD=7.0) yrs. MetS was defined as having at least three of the following risk factors: abdominal obesity, fasting hypertriglyceridemia, low high-density lipoprotein cholesterol, high blood pressure, or high fasting glucose level or diabetes. MetS was associated with higher mortality (HR=1.90 [95% Confidence Interval=1.42-2.55]), and there was a graded positive association for the addition …

Body Image In Middle-Aged Mormon Women: A Comparative Case Study, Janette Olsen
Faculty Publications
Body image is a multifaceted construct developed from perceived experiences and personal and cultural attitudes towards the body. Women are more vulnerable than men to internal and external influences regarding negative body image. A qualitative comparative case study design was utilized to explore how 10 lifelong, middle-aged LDS women, either married (n=5) with children or single, never married (n=5), experienced body image through their perceptions of religiosity and spirituality. The participants lived along the Wasatch Front in Utah and were recruited through known LDS gatekeepers. Each participant completed three in-person interviews and three audio or paper journals, which were transcribed …

Background: The quality and quantity of individuals' social relationships has been linked not only to mental health but also to both morbidity and mortality. Objectives: This meta-analytic review was conducted to determine the extent to which social relationships influence risk for mortality, which aspects of social relationships are most highly predictive, and which factors may moderate the risk. Data Extraction: Data were extracted on several participant characteristics, including cause of mortality, initial health status, and pre-existing health conditions, as well as on study characteristics, including length of follow-up and type of assessment of social relationships. Results: Across 148 studies (308,849 …

Faculty Publications
When challenged by low-iron conditions several Gram-negative pathogens secrete a hemophore (HasA) to scavenge hemin from its host and deliver it to a receptor (HasR) on their outer membrane for internalization. Here we report results from studies aimed at probing the structural and dynamic processes at play in the loading of the apo-hemophore secreted by P. aeruginosa (apo-HasAp) with hemin. The structure of apo-HasAp shows a large conformational change in the loop harboring axial ligand His32 relative to the structure of holo-HasAp, whereas the loop bearing the other axial ligand, Tyr75, remains intact. To investigate the role played by the …

The Role Of Religion And Spirituality In Olav’S Treatment And Recovery: Commentary On An Exemplary Case Report, P. Scott Richards
Faculty Publications
The Case of Olav (Stålsett, Engedal, & Austad, 2010) offers in-depth insight from a spiritually and existentially informed psychodynamic perspective of how religious and spiritual issues may be intertwined with psychopathology. This case report also shows how psychological and spiritual interventions can be used in an integrative manner to help patients with severe long- term psychopathology. Ultimately the case provides convincing quantitative and qualitative evidence that an in-depth working through of Olav’s pathological inner representations of self and God were instrumental in his psycho-spiritual healing and recovery.

Beyond Employment And Income: The Association Between Young Adults’ Finances And Marital Timing, Jeffrey P. Dew, Joseph Price
Faculty Publications
This study tested an extension of the theory of marital timing (Oppenheimer, Am J Sociol 94:563–591, 1988) by assessing whether visible and less visible financial assets and debt mediated the relationship between employment and the likelihood of marriage. We conducted these prospective, longitudinal analyses using a sample of 1,522 never-married young adults from the National Survey of Families and Households. For participants who were not cohabiting at Wave 1, financial issues such as car values predicted marriage but did not mediate the relationship between work hours, occupational prestige, and the likelihood of marriage. For cohabiting participants, employment factors were the …

Oxygen Is Required For The L-Cysteine-Mediated Decomposition Of Protein-Bound Dinitrosyl-Iron Complexes, Juanjuan Yang, Xuewu Duan, Aaron P. Landry, Huangen Ding
Faculty Publications
Increasing evidence suggests that iron-sulfur proteins are the primary targets of nitric oxide (NO). Exposure of Escherichia coli cells to NO readily converts iron-sulfur proteins to protein-bound dinitrosyl-iron complexes (DNICs). Although the protein-bound DNICs are stable in vitro under aerobic or anaerobic conditions, they are efficiently repaired in aerobically growing E. coli cells even without new protein synthesis. The cellular repair mechanism for the NO-modified iron-sulfur proteins remains largely elusive. Here we report that, unlike aerobically growing E. coli cells, starved E. coli cells fail to reactivate the NO-modified iron-sulfur proteins. Significantly, the addition of l-cysteine, but not other related …

High-throughput DNA sequencing can identify organisms and describe population structures in many environmental and clinical samples. Current technologies generate millions of reads in a single run, requiring extensive computational strategies to organize, analyze and interpret those sequences. A series of bioinformatics tools for high-throughput sequencing analysis, including pre-processing, clustering, database matching and classification, have been compiled into a pipeline called PANGEA. The PANGEA pipeline was written in Perl and can be run on Mac OSX, Windows or Linux. With PANGEA, sequences obtained directly from the sequencer can be processed quickly to provide the files needed for sequence identification by BLAST …

Behavioral And Physiological Plasticity: Rapid Changes During Social Ascent In An African Cichlid Fish, Karen P. Maruska, Russell D. Fernald
Faculty Publications
In many vertebrates, reproduction is regulated by social interactions in which dominant males control access to females and food. Subordinate males that displace dominant individuals must rapidly adopt behavioral and physiological traits of the higher rank to gain reproductive success. To understand the process of phenotypic plasticity during social ascent, we analyzed the temporal expression pattern of dominance behaviors and circulating androgen levels when socially-suppressed males of an African cichlid fish Astatotilapia burtoni ascended in status. These experiments tested a prediction of the 'challenge hypothesis' that, during periods of social instability, male androgen levels are higher than during socially stable …

Thrombostasin (TS) is an anticlotting protein found in saliva of Haematobia irritons (horn flies). The polymorphic nature of the ts gene was first associated with success of horn flies blood feeding on a laboratory host, New Zealand White rabbits. In this study, we report results of similar studies testing blood uptake of horn flies feeding on a natural host, cattle. These studies confirmed the association of ts genotype with blood uptake of horn flies and showed that it was host species specific. In contrast to rabbits, blood uptake volumes of homozygous ts10 horn flies were lower than those of other …

In the United States, petroleum extraction, refinement, and transportation present countless opportunities for spillage mishaps. A method for rapid field appraisal and mapping of petroleum hydrocarbon-contaminated soils for environmental cleanup purposes would be useful. Visible near-infrared (VisNIR, 350-2500 nm) diffuse reflectance spectroscopy (DRS) is a rapid, nondestructive, proximal-sensing technique that has proven adept at quantifying soil properties in situ. The objective of this study was to determine the prediction accuracy of VisNIR DRS in quantifying petroleum hydrocarbons in contaminated soils. Forty-six soil samples (including both contaminated and reference samples) were collected from six different parishes in Louisiana. Each soil sample …

Co-Varying Patterns Of Physical Activity And Sedentary Behaviors And Their Long-Term Maintenance Among Adolescents, Jihong Liu, Jinseok Kim, Natalie Colabianchi, Andrew Ortaglia, Russell R. Pate
Faculty Publications
Background: We examined the covarying patterns of physical activity and sedentary behaviors among adolescents and their long-term maintenance. Methods: Data came from the National Longitudinal Study of Adolescent Health (1995-2002). We used latent class analysis to identify distinct covarying patterns in adolescence. Logistic regression models were used to predict odds of meeting moderate-to-vigorous physical activity (MVPA) recommendations (≥5 bouts/week) and exceeding screen time guidelines (>2 hours/day) 6 years later based on their adolescent class profile. Results: Five classes for each gender were identified and labeled as low physical activity (PA)/low sedentary behaviors (SED), moderate (Mod) PA/high (HI) SED, Mod …
