Screenhouse Transmission Of Beauveria Bassiana From Infected To Non-Infected Adults Of Banana Weevil, C. A. Omukoko, J. M. Wesonga, E. M. Kahangi, L. S. Wamocho, K. N. Maniania

All Peer-Reviewed Publications

Laboratory studies have revealed great potential of entomopathogenic fungus Beauveria bassiana for use against the banana weevil, Cosmopolites sordidus, in banana. Adult banana weevils exposed to wet conidia of Beauveria bassiana suffered high mortalities ranging from 50-70% by 40 days post exposure when a concentration of 1×109 was used in the laboratory with three isolates ICIPE 273, M313 and M207 which were selected on the basis of high virulence against C. sordidus and high sporulation. However, impractical field delivery methods and high costs associated with the application of B. bassiana against C. sordidus prevent its use and commercialisation in banana …

The Effect Of Shifts In Medium Types On The Growth And Morphology Of Spirulina Platensis (Arthrospira Platensis), Yean-Chang Chen

Journal of Marine Science and Technology–Taiwan

In order to reduce the cultural cost and increase the biomass of Spirulina platensis cultures, two basic culture media were used in the present study, the Zarrouk (Z9) and Provasoli's enriched seawater (PES) media. They were re-modified into five media by adding varied concentrations of NaCl, NaHCO3 and seawater (salinity). S. platensis could grow well in all of these media. The Z9 medium provided the best growth rate at the end of culture and the PES medium provided the best initial growth curve slope. After the media were shifted from PES to Z9, the long algal filaments fragmented to form …

Role Of Exonic Variation In Chemokine Receptor Genes On Aids: Ccrl2 F167y Association With Pneumocystis Pneumonia, Ping An, Rongling Li, Ji Ming Wang, Teizo Yoshimura, Munehisa Takahashi, Ram Samudralal, Stephen J. O'Brien, John Phair, James J. Goedert, Gregory D. Kirk, Jennifer L. Troyer, Efe Sezgin, Susan Buchbinder, Sharyne Donfield, George W. Nelson, Cheryl Winkler

Biology Faculty Articles

Chromosome 3p21–22 harbors two clusters of chemokine receptor genes, several of which serve as major or minor coreceptors of HIV-1. Although the genetic association of CCR5 andCCR2 variants with HIV-1 pathogenesis is well known, the role of variation in other nearby chemokine receptor genes remain unresolved. We genotyped exonic single nucleotide polymorphisms (SNPs) in chemokine receptor genes: CCR3, CCRL2, and CXCR6 (at 3p21) and CCR8 and CX3CR1 (at 3p22), the majority of which were non-synonymous. The individual SNPs were tested for their effects on disease progression and outcomes in five treatment-naïve HIV-1/AIDS natural history cohorts. In …

Loss-Of-Function Of Constitutive Expresser Of Pathogenesis Related Genes5 Affects Potassium Homeostasis In Arabidopsis Thaliana, Monica Borghi, Ana Rus, David E. Salt

Biology Faculty Publications

Here, we demonstrate that the reduction in leaf K+ observed in a mutant previously identified in an ionomic screen of fast neutron mutagenized Arabidopsis thaliana is caused by a loss-of-function allele of CPR5, which we name cpr5-3. This observation establishes low leaf K+ as a new phenotype for loss-of-function alleles of CPR5. We investigate the factors affecting this low leaf K+ in cpr5 using double mutants defective in salicylic acid (SA) and jasmonic acid (JA) signalling, and by gene expression analysis of various channels and transporters. Reciprocal grafting between cpr5 and Col-0 was used to determine the relative importance of …

Molecular Diversity Of Fungal Phylotypes Co-Amplified Alongside Nematodes From Coastal And Deep-Sea Marine Environments, Punyasloke Bhadury, Holly Bik, John D. Lambshead, Melanie C. Austen, Gary R. Smerdon, Alex D. Rogers

Hubbard Center for Genome Studies (HCGS)

Nematodes and fungi are both ubiquitous in marine environments, yet few studies have investigated relationships between these two groups. Microbial species share many well-documented interactions with both free-living and parasitic nematode species, and limited data from previous studies have suggested ecological associations between fungi and nematodes in benthic marine habitats. This study aimed to further document the taxonomy and distribution of fungal taxa often co-amplified from nematode specimens. A total of 15 fungal 18S rRNA phylotypes were isolated from nematode specimens representing both deep-sea and shallow water habitats; all fungal isolates displayed high pairwise sequence identities with published data in …

Composition Of Two Seaweed-Oligosaccharide-Lysates Derived From Agarase As-Ii And Their Ferrous-Chelating Antioxidant Power, Fu-Jin Wang, Sheen-Kye Kang, Chorng-Liang Pan, Shao-Chi Wu

Journal of Marine Science and Technology–Taiwan

Seaweed-oligosaccharide-lysates (SwOSLys) Gra-C108, Mon-C108, Gra-AS-II, or Mon-AS-II are seaweed polysaccharide extracts (SwPSExts) Gra or Mon, which are digested by either Aeromonas (A.) salmonicida MAEF108 crude agarases or Agarase AS-II that was produced from marine bacteria A. salmonicida MAEF108. High-performance liquid chromatography revealed that there were neoagarohexaose and neoagarotetraose in both Gra-C108 and Gra-AS-II and that neoagarooligosaccharide was absent in both Mon-C108 and Mon-AS-II. The polyphenol content of SwOSLys was higher than that of SwPSExts, though without significant difference (p < 0.05) on lysates, as digested by crude MAEF108-agarases or Agarase AS-II. Comparison of the chelating effects of GraC108 and Gra-AS-II on Fe2+ shows that not only do the polyphenolic compound but also the neoagarooligosaccharide show antioxidative properties.

The Tubulin Deglutamylase Ccpp-1 Regulates The Function And Stability Of Sensory Cilia In C. Elegans, Robert O'Hagan, Brian P. Piasecki, Malan Silva, Prasad Phirke, Ken C Q Nguyen, David H. Hall, Peter Swoboda, Maureen M. Barr

Department of Biology Faculty Scholarship and Creative Works

Background: Posttranslational modifications (PTMs) such as acetylation, detyrosination, and polyglutamylation have long been considered markers of stable microtubules and have recently been proposed to guide molecular motors to specific subcellular destinations. Microtubules can be deglutamylated by the cytosolic carboxypeptidase CCP1. Loss of CCP1 in mice causes cerebellar Purkinje cell degeneration. Cilia, which are conserved organelles that play important diverse roles in animal development and sensation, contain axonemes comprising microtubules that are especially prone to PTMs. Results: Here, we report that a CCP1 homolog, CCPP-1, regulates the ciliary localization of the kinesin-3 KLP-6 and the polycystin PKD-2 in male-specific sensory neurons …

Reversal Of Glial And Neurovascular Markers Of Unhealthy Brain Aging By Exercise In Middle-Aged Female Mice, Caitlin S. Latimer, James L. Searcy, Michael T. Bridges, Lawrence D. Brewer, Jelena Popović, Eric M. Blalock, Philip W. Landfield, Olivier Thibault, Nada M. Porter

Pharmacology and Nutritional Sciences Faculty Publications

Healthy brain aging and cognitive function are promoted by exercise. The benefits of exercise are attributed to several mechanisms, many which highlight its neuroprotective role via actions that enhance neurogenesis, neuronal morphology and/or neurotrophin release. However, the brain is also composed of glial and vascular elements, and comparatively less is known regarding the effects of exercise on these components in the aging brain. Here, we show that aerobic exercise at mid-age decreased markers of unhealthy brain aging including astrocyte hypertrophy, a hallmark of brain aging. Middle-aged female mice were assigned to a sedentary group or provided a running wheel for …

Thrombospondin1 Deficiency Reduces Obesity-Associated Inflammation And Improves Insulin Sensitivity In A Diet-Induced Obese Mouse Model, Yanzhang Li, Xiaopeng Tong, Courtney Rumala, Kate Clemons, Shuxia Wang

Graduate Center for Nutritional Sciences Faculty Publications

BACKGROUND: Obesity is prevalent worldwide and is associated with insulin resistance. Advanced studies suggest that obesity-associated low-grade chronic inflammation contributes to the development of insulin resistance and other metabolic complications. Thrombospondin 1 (TSP1) is a multifunctional extracellular matrix protein that is up-regulated in inflamed adipose tissue. A recent study suggests a positive correlation of TSP1 with obesity, adipose inflammation, and insulin resistance. However, the direct effect of TSP1 on obesity and insulin resistance is not known. Therefore, we investigated the role of TSP1 in mediating obesity-associated inflammation and insulin resistance by using TSP1 knockout mice.

METHODOLOGY/PRINCIPAL FINDINGS: Male TSP1-/- mice …

The Knowledge-Driven Exploration Of Integrated Biomedical Knowledge Sources Facilitates The Generation Of New Hypotheses, Vinh Nguyen, Olivier Bodenreider, Todd Minning, Amit P. Sheth

Kno.e.sis Publications

Knowledge gained from the scientific literature can complement newly obtained experimental data in helping researchers understand the pathological processes underlying diseases. However, unless the scientific literature and experimental data are semantically integrated, it is generally difficult for scientists to exploit the two sources effectively. We argue that, in addition to the semantic integration of heterogeneous knowledge sources, the usability of the integrated resource by scientists is dependent upon the availability of knowledge visualization and exploration tools. Moreover, the integration techniques must be scalable and the exploration interfaces must be easy to use by bench scientists. The end goal of such …

The Group-Level Consequences Of Sexual Conflict In Multigroup Populations, Omar Tonsi Eldakar, Andrew C. Gallup

Biology Faculty Articles

In typical sexual conflict scenarios, males best equipped to exploit females are favored locally over more prudent males, despite reducing female fitness. However, local advantage is not the only relevant form of selection. In multigroup populations, groups with less sexual conflict will contribute more offspring to the next generation than higher conflict groups, countering the local advantage of harmful males. Here, we varied male aggression within-and between-groups in a laboratory population of water striders and measured resulting differences in local population growth over a period of three weeks. The overall pool fitness (i.e., adults produced) of less aggressive pools exceeded …

This paper demonstrates a Semantic Web enabled system for collecting and processing sensor data within a rescue environment. The real-time system collects heterogeneous raw sensor data from rescue robots through a wireless sensor network. The raw sensor data is converted to RDF using the Semantic Sensor Network (SSN) ontology and further processed to generate abstractions used for event detection in emergency scenarios.

Demonstration: Real-Time Semantic Analysis Of Sensor Streams, Harshal Patni, Cory Andrew Henson, Michael Cooney, Amit P. Sheth, Krishnaprasad Thirunarayan

Kno.e.sis Publications

The emergence of dynamic information sources – including sensor networks – has led to large streams of real-time data on the Web. Research studies suggest, these dynamic networks have created more data in the last three years than in the entire history of civilization, and this trend will only increase in the coming years [1]. With this coming data explosion, real-time analytics software must either adapt or die [2]. This paper focuses on the task of integrating and analyzing multiple heterogeneous streams of sensor data with the goal of creating meaningful abstractions, or features. These features are then temporally aggregated …

Identification And Thermochemical Analysis Of High-Lignin Feedstocks For Biofuel And Biochemical Production, Venugopal Mendu, Anne E. Harman-Ware, Mark Crocker, Jungho Jae, Jozsef Stork, Samuel Morton, Andrew Placido, George Huber, Seth Debolt

Horticulture Faculty Publications

BACKGROUND: Lignin is a highly abundant biopolymer synthesized by plants as a complex component of plant secondary cell walls. Efforts to utilize lignin-based bioproducts are needed.

RESULTS: Herein we identify and characterize the composition and pyrolytic deconstruction characteristics of high-lignin feedstocks. Feedstocks displaying the highest levels of lignin were identified as drupe endocarp biomass arising as agricultural waste from horticultural crops. By performing pyrolysis coupled to gas chromatography-mass spectrometry, we characterized lignin-derived deconstruction products from endocarp biomass and compared these with switchgrass. By comparing individual pyrolytic products, we document higher amounts of acetic acid, 1-hydroxy-2-propanone, acetone and furfural in switchgrass …

The ten described species transferred to Neothlipsis are:, Neothlipsis agathoides, comb. n. for Bassus agathoides Newton and Sharkey 2000; Neothlipsis agilis, comb. n. for Bassus agilis Cresson 1868; Neothlipsis brevicauda, comb. n. for Bassus brevicaudus Muesebeck 1932; Neothlipsis californica, comb. n. for Bassus californicus Muesebeck 1927; Neothlipsis cincta, comb. n. for Microdus …

Guantánamo Bodies: Law, Media, And Biopower, Cary H. Federman, Dave Holmes

Department of Justice Studies Faculty Scholarship and Creative Works

The idea of the Guantánamo detainee as a Muselmann, the lowest order of concentration camp inmates, contains within it important implications for the new understanding of sovereignty in the era of Guantánamo, in an age of exception. The purpose of this article is to explain the status of those who are detained at Guantánamo Bay. Stated broadly, in assessing that status, we will emphasize the connection between the altered meaning of sovereignty that has accompanied the placing of prisoners in an American penal colony in Cuba and the biopolitical status of the prisoners who reside there. More particularly, we …

The Effect Of Exercise Mode And Intensity Of Submaximal Physical Activities On Salivary Testosterone To Cortisol Ratio And Α-Amylase In Young Active Males, Mohammad Ali Azarbayjani, Hoseyn Fatolahi, Mohammad Javad Rasaee, Maghsod Peeri, Roholah Babaei

International Journal of Exercise Science

We examined the effect of exercise intensity and mode on the acute responses of free testosterone to cortisol ratio and salivary α-amylase. We also evaluated the relationship between cortisol and salivary α-amylase. Ten healthy young active males participated voluntarily in this study in six single sessions. They exercised on a cycle ergo meter, treadmill, and elliptical instrument at intensities of 70% and 85% maximum heart rate for 25 minutes. Saliva samples were collected 5 minutes before and 5 minutes after each exercise session. No significant changes were observed for cortisol. Free testosterone to cortisol ratio increased during each exercise session …

Influence Of Differences In Exercise-Intensity And Kilograms/Set On Energy Expenditure During And After Maximally Explosive Resistance Exercise, Scott A. Mazzetti Ph.D., Christopher Wolff, Brittany Collins, Michael T. Kolankowski, Brittany Wilkerson, Matthew Overstreet, Troy Grube

International Journal of Exercise Science

With resistance exercise, greater intensity typically elicits increased energy expenditure, but heavier loads require that the lifter perform more sets of fewer repetitions, which alters the kilograms lifted per set. Thus, the effect of exercise-intensity on energy expenditure has yielded varying results, especially with explosive resistance exercise. This study was designed to examine the effect of exercise-intensity and kilograms/set on energy expenditure during explosive resistance exercise. Ten resistance-trained men (22±3.6 years; 84±6.4 kg, 180±5.1 cm, and 13±3.8 %fat) performed squat and bench press protocols once/week using different exercise-intensities including 48% (LIGHT-48), 60% (MODERATE-60), and 72% of 1-repetition-maximum (1-RM) (HEAVY-72), plus …

Impact Of Exercise Partner Attractiveness On Mood, Enjoyment, And Exertion, Thomas G. Plante, Sarah Gregg, Jaclyn Rubbo, Thomas Favero, Ashley Morisako, Jessica Cuadra

International Journal of Exercise Science

Social comparison theory was used to examine if males exercising with a female research confederate posing as either attractive or unattractive would alter their exercise mood, exertion, and enjoyment. A total of 101 college students (51 males and 51 females) were randomly assigned to one of three conditions: biking alone, biking with an attractive female confederate, or biking with the same female confederate appearing unattractive. All participants were instructed to complete 20 minutes of exercise at 60%-70% of their maximum target heart rate. Standard exercise mood measures (e.g., Activation-Deactivation Adjective Check List) were administered immediately prior to and immediately following …

Do Exergames Allow Children To Achieve Physical Activity Intensity Commensurate With National Guidelines?, Rachel Perron, Courtney Graham, Jamie Feldman, Rebecca Moffett, Eric E. Hall

International Journal of Exercise Science

The purpose of this study was to determine if two popular exergames, Wii Fit™ and EA Sports Active™, both games for the Nintendo Wii™ console, help children achieve intensity consistent with recommended physical activity guidelines. Thirty children (19 males and 11 females, Mean age = 9.4 ± 1.8 years) participated in this study by playing each game during one research session. During the session participants wore a heart rate monitor and accelerometer to measure exercise intensity. Perceived exertion (RPE) was measured with the children’s run/walk OMNI scale. All three measures of exercise intensity (heart rate, accelerometer counts, and RPE) found …
