Nomenclatural And Taxonomic Changes In Staphyliniformia (Coleoptera), Alfred F. Newton

Insecta Mundi

Many nomenclatural changes are implemented in the beetle families Georissidae, Histeridae, Hydraenidae, Hydrochidae, Hydrophilidae, Ptiliidae, Leiodidae and especially Staphylinidae, of the beetle series Staphyliniformia (Coleoptera), in preparation for making a world catalog of this group available online. Limited taxonomic changes are also made in the staphylinid subfamilies Osoriinae and Staphylininae.

At the level of family-group taxa, Article 29.4 of the current (1999) Zoological Code is reviewed and the original spellings of two tribal names, Nymphisterini Tishechkin (Histeridae) and Cryptonotopsisini Pace (Staphylinidae), are resurrected. The tribal name Stictocraniini Jakobson (Staphylinidae) is also resurrected as the valid name for its new synonym …

High Fructose Corn Syrup Induces Metabolic Dysregulation And Altered Dopamine Signaling In The Absence Of Obesity, Allison M. Meyers, Devry Mourra, Jeff A. Beeler

Publications and Research

The contribution of high fructose corn syrup (HFCS) to metabolic disorder and obesity, independent of high fat, energy-rich diets, is controversial. While high-fat diets are widely accepted as a rodent model of diet-induced obesity (DIO) and metabolic disorder, the value of HFCS alone as a rodent model of DIO is unclear. Impaired dopamine function is associated with obesity and high fat diet, but the effect of HFCS on the dopamine system has not been investigated. The objective of this study was to test the effect of HFCS on weight gain, glucose regulation, and evoked dopamine release using fast-scan cyclic voltammetry. …

Leishmaniasis is a parasitic infection that afflicts approximately 12 million people worldwide. There are several limitations to the approved drug therapies for leishmaniasis, including moderate to severe toxicity, growing drug resistance, and the need for extended dosing. Moreover, miltefosine is currently the only orally available drug therapy for this infection. We addressed the pressing need for new therapies by pursuing a two-step phenotypic screen to discover novel, potent, and orally bioavailable antileishmanials. First, we conducted a high-throughput screen (HTS) of roughly 600,000 small molecules for growth inhibition against the promastigote form of the parasite life cycle using the nucleic acid …

Forest Floor And Mineral Soil Respiration Rates In A Northern Minnesota Red Pine Chronosequence, Matthew Powers, Randall K Kolka, John Bradford, Brian Palik, Martin F. Jurgensen

Michigan Tech Publications, Part 1

We measured total soil CO₂ efflux (R_S) and efflux from the forest floor layers (R_FF) in red pine (Pinus resinosa Ait.) stands of different ages to examine relationships between stand age and belowground C cycling. Soil temperature and R_S were often lower in a 31-year-old stand (Y31) than in 9-year-old (Y9), 61-year-old (Y61), or 123-year-old (Y123) stands. This pattern was most apparent during warm summer months, but there were no consistent differences in R_FF among different-aged stands. R_FF represented an average of 4–13% of total soil respiration, and forest floor removal increased …

A Highly Stable Blood Meal Alternative For Rearing Aedes And Anopheles Mosquitoes, Ted Baughman, Chelsea Peterson, Corrie Ortega, Sarah R. Preston, Christopher Paton, Jessica Williams, Amy Guy, Gavin Omodei, Brian Johnson, Helen Williams, Scott L. O'Neill, Scott A. Ritchie, Stephen L. Dobson, Damian Madan

We investigated alternatives to whole blood for blood feeding of mosquitoes with a focus on improved stability and compatibility with mass rearing programs. In contrast to whole blood, an artificial blood diet of ATP-supplemented plasma was effective in maintaining mosquito populations and was compatible with storage for extended periods refrigerated, frozen, and as a lyophilized powder. The plasma ATP diet supported rearing of both Anopheles and Aedes mosquitoes. It was also effective in rearing Wolbachia-infected Aedes mosquitoes, suggesting compatibility with vector control efforts.

Multiple Functions Of Creb-Binding Protein During Postembryonic Development: Identification Of Target Genes, Amit Roy, Smitha George, Subba Reddy Palli

Entomology Faculty Publications

Background: Juvenile hormones (JH) and ecdysteroids control postembryonic development in insects. They serve as valuable targets for pest management. Hence, understanding the molecular mechanisms of their action is of crucial importance. CREB-binding protein (CBP) is a universal transcriptional co-regulator. It controls the expression of several genes including those from hormone signaling pathways through co-activation of many transcription factors. However, the role of CBP during postembryonic development in insects is not well understood. Therefore, we have studied the role of CBP in postembryonic development in Tribolium, a model coleopteran insect.

Results: CBP is ubiquitously expressed in the red flour beetle, …

Improvements To Bayesian Gene Activity State Estimation From Genome-Wide Transcriptomics Data, Craig Disselkoen, Nathan Hekman, Brian Gilbert, Sydney Benson, Matthew Anderson, Matthew Dejongh, Aaron Best, Nathan L. Tintle

Faculty Work Comprehensive List

An important question in many biological applications, is to estimate or classify gene activity states (active or inactive) based on genome-wide transcriptomics data. Recently, we proposed a Bayesian method, titled MultiMM, which showed superior results compared to existing methods. In short, MultiMM performed better than existing methods on both simulated and real gene expression data, confirming well-known biological results and yielding better agreement with fluxomics data. Despite these promising results, MultiMM has numerous limitations. First, MultiMM leverages co-regulatory models to improve activity state estimates, but information about co-regulation is incorporated in a manner that assumes that networks are known with …

Dengue And Yellow Fever Virus Vectors: Seasonal Abundance, Diversity And Resting Preferences In Three Kenyan Cities, Sheila B. Agha, David P. Tchouassi, Armanda D.S. Bastos, Rosemary Sang

All Peer-Reviewed Publications

Background: The transmission patterns of dengue (DENV) and yellow fever (YFV) viruses, especially in urban settings, are influenced by Aedes (Stegomyia) mosquito abundance and behavior. Despite recurrent dengue outbreaks on the Kenyan coast, these parameters remain poorly defined in this and other areas of contrasting dengue endemicity in Kenya. In assessing the transmission risk of DENV/YFV in three Kenyan cities, we determined adult abundance and resting habits of potential Aedes (Stegomyia) vectors in Kilifi (dengue-outbreak prone), and Nairobi and Kisumu (no dengue outbreaks reported). In addition, mosquito diversity, an important consideration for changing mosquito-borne disease dynamics, was compared. Methods: Between …
