Systematics Of Isocarpha (Compositae: Eupatorieae), David J. Keil, Tod F. Stuessy 2010 California Polytechnic State University - San Luis Obispo

Systematics Of Isocarpha (Compositae: Eupatorieae), David J. Keil, Tod F. Stuessy

David J. Keil

Isocarpha comprises five species ranging from southern Texas and the Bahamas to northern Peru and northeastern Brazil. The genus belongs in Eupatorieae rather than Heliantheae, but structure of the head of Isocarpha with its elongate, chaffy receptacle is anomalous within Eupatorieae. An hypothesis is presented suggesting the evolutionary derivation of this type of head through formation of floral buds in the axils of the involucral bracts. Generic ties of Isocarpha within Eupatorieae are unclear, but the closest affinities appear to be with Ayapana and relatives.

A Single Residue Switch For Mg2+-Dependent Inhibition Characterizes Plant Class Ii Diterpene Cyclases From Primary And Secondary Metabolism, Francis M. Mann, Sladjana Prisic, Emily K. Davenport, Mara K. Determan, Robert M. Coates, Reuben J. Peters 2010 Iowa State University

A Single Residue Switch For Mg2+-Dependent Inhibition Characterizes Plant Class Ii Diterpene Cyclases From Primary And Secondary Metabolism, Francis M. Mann, Sladjana Prisic, Emily K. Davenport, Mara K. Determan, Robert M. Coates, Reuben J. Peters

Biochemistry, Biophysics and Molecular Biology Publications

Class II diterpene cyclases mediate the acid-initiated cycloisomerization reaction that serves as the committed step in biosynthesis of the large class of labdane-related diterpenoid natural products, which includes the important gibberellin plant hormones. Intriguingly, these enzymes are differentially susceptible to inhibition by their Mg2+ cofactor, with those involved in gibberellin biosynthesis being more sensitive to such inhibition than those devoted to secondary metabolism, which presumably limits flux toward the potent gibberellin phytohormones. Such inhibition has been suggested to arise from intrasteric Mg2+ binding to the DXDD motif that cooperatively acts as the catalytic acid, whose affinity ...


A Taxonomic Review Of The Neotropical Genus Coprophanaeus Olsoufieff, 1924 (Coleoptera: Scarabaeidae, Scarabaeinae, W. D. Edmonds, J. Zidek 2010 Marfa, Texas 79843, USA

A Taxonomic Review Of The Neotropical Genus Coprophanaeus Olsoufieff, 1924 (Coleoptera: Scarabaeidae, Scarabaeinae, W. D. Edmonds, J. Zidek

Insecta Mundi

The Neotropical genus Coprophanaeus Olsoufieff (1924), as classified here, comprises 38 species distributed among three subgenera (Megaphanaeus Olsoufieff, Metallophanaeus Olsoufieff, and Coprophanaeus s. str. ) and eight species groups. Keys presented help to identify supraspecific and species taxa, all of which are illustrated and diagnosed. Lectotypes are designated for Phanaeus ignecinctus Felsche and Phanaeus ohausi Felsche. Coprophanaeus corythus (Harold), formerly regarded as a subspecies of C. telamon (Erichson), assumes species status. Coprophanaeus magnoi Arnaud, described as a subspecies of C. milon (Blanchard), is raised to species status. New taxonomic interpretations result in 10 new subjective synonymies (junior synonym listed first): Phanaeus ...


Is It Possible (Or Wise) To Put Farmland In An Ira?, Neil E. Harl 2010 Iowa State University

Is It Possible (Or Wise) To Put Farmland In An Ira?, Neil E. Harl

Agricultural Law Digest

The economic downturn in the past couple of years coupled with low commodity prices for milk, hogs and a few other commodities has focused attention on appropriate strategies if the decision is made to file bankruptcy.1 Among those strategies, and one of the most important, is the decision to elect to close an individual debtor’s tax year if the filing is under Chapter 7 liquidation or Chapter 11 reorganization.2 The election opportunity does not apply to those filing under other chapters of the Bankruptcy Code (Chapters 9, 12 or 13) nor does it apply to partnerships, corporations ...

Chronic Amp-Activated Protein Kinase Activation And A High-Fat Diet Have An Additive Effect On Mitochondria In Rat Skeletal Muscle, Natasha Fillmore 2010 Brigham Young University - Provo

Chronic Amp-Activated Protein Kinase Activation And A High-Fat Diet Have An Additive Effect On Mitochondria In Rat Skeletal Muscle, Natasha Fillmore

All Theses and Dissertations

Factors that stimulate mitochondrial biogenesis in skeletal muscle include AMPK, calcium, and circulating FFAs. Chronic treatment with either AICAR, a chemical activator of AMPK, or increasing circulating FFAs with a high fat diet increases mitochondria in rat skeletal muscle. The purpose of this study was to determine whether the combination of chronic chemical activation of AMPK and high fat feeding would have an additive effect on skeletal muscle mitochondria levels. We treated Wistar male rats with a high fat diet (HF), AICAR injections (AICAR), or a high fat diet and AICAR injections (HF+AICAR) for six weeks. At the end ...


Anti-Depressive And Anti-Obesity Changes Following Either Dietary Isoflavone Treatment Or Injection Treatment With The Isoflavonoid Equol: Positive Response Dependent On Animal Age And Ovarian Status In Female Long Evans Rats, Crystal Blake 2010 Brigham Young University - Provo

Anti-Depressive And Anti-Obesity Changes Following Either Dietary Isoflavone Treatment Or Injection Treatment With The Isoflavonoid Equol: Positive Response Dependent On Animal Age And Ovarian Status In Female Long Evans Rats, Crystal Blake

All Theses and Dissertations

Two conditions associated with ovarian depletion are increased potential for depressive episodes and increased abdominal weight gain. In five different experiments we examined the effect of soy-containing diets or equol injections on depression, serotonin levels, weight gain (BW) and white adipose tissue (WAT) deposition of female Long-Evans rats in various stages of life. Rats were intact, ovariectomized or experienced natural ovarian failure (NOF). While this paper will present each experiment, only experiment 5 is outlined here due to space limitations. From conception the rats were exposed to either a soy-rich (Phyto-600) or low-soy diet (Phyto-low). Animals experienced NOF at approximately ...


Landscape-Scale And Macrohabitat-Scale Variation In Growth And Survival Of Young June Sucker (Chasmistes Liorus) In Utah Lake, Joshua Daniel Kreitzer 2010 Brigham Young University - Provo

Landscape-Scale And Macrohabitat-Scale Variation In Growth And Survival Of Young June Sucker (Chasmistes Liorus) In Utah Lake, Joshua Daniel Kreitzer

All Theses and Dissertations

The spatial scales at which ecological phenomena are viewed constrain the results of interactions between species and their environments. In lake ecosystems, important dynamics have been identified at the landscape scale and the macrohabitat scale. To determine if landscape-scale effects and macrohabitat-scale effects are important in survival and growth of young June suckers, we compared variation among sites in Utah Lake. Large semi-permeable cages were used to house June suckers in situ at five sites representing landscape-scale variation and two sites representing macrohabitat-scale variation in Utah Lake. We compared survival and growth among sites and related it to resource availability ...


Assessing Traditional Morphology- And Chemistry-Based Species Circumspections In Lichenized Ascomycetes: Character Evolution And Molecular Species Delimitation In Common Western North American Lichens, Steven Leavitt 2010 Brigham Young University - Provo

Assessing Traditional Morphology- And Chemistry-Based Species Circumspections In Lichenized Ascomycetes: Character Evolution And Molecular Species Delimitation In Common Western North American Lichens, Steven Leavitt

All Theses and Dissertations

Accurate species delimitation has critical implications for ecological and conservation studies; and for understanding factors driving diversification. However, a growing body of evidence indicates that morphology-based species circumspection in lichenized ascomycetes often fails to accurately represent the number of fungal species. The use of molecular data in lichen systematics provides an important alternative to traditional morphological characters for identifying natural groups and assessing evolutionary histories in challenging lichen taxa. In this work, I examined two common lichen-forming genera in western North America, Rhizoplaca and Xanthoparmelia, as models for investigating character evolution, species delimitation in morphologically and chemically diverse species, and ...


Hydroxyl-Terminated Poly(Urethane Acrylate) As A Soft Liner In Dental Applications: Synthesis And Characterization, SELDA KESKIN 2010 The Pennsilyvania State University, Department of Chemistry

Hydroxyl-Terminated Poly(Urethane Acrylate) As A Soft Liner In Dental Applications: Synthesis And Characterization, Selda Keskin


ABSTRACT: Hydroxyl-terminated poly(urethane acrylate) s were synthesized for use in biomedical applications. Acrylate end capping via an interesterification reaction was successfully achieved with methacryloyl chloride addition to the hydroxyl ends of the polyurethane at low temperatures. 2,4-Toluene diisocyanate, 1,6-hexane diisocyanate, and methylene diphenyl diisocyanate were used as diisocyanates for urethane synthesis, and they were end-capped with methyl methacrylate and hydroxyethyl methacrylate. The nature of the monomers that we used had an effect on the thermal and morphological properties that were interpreted in terms of the level of hydrogen bonding and the degree of phase separation. The synthesized ...

Histone H2a And H2b Are Monoubiquitinated At Aid-Targeted Loci, Glen M. Borchert, Nathaniel W. Holton, Kevin A. Edwards, Laura A. Vogel, Erik D. Larson

Faculty Publications – Biological Sciences

Background: Somatic hypermutation introduces base substitutions into the rearranged and expressed immunoglobulin (Ig) variable regions to promote immunity. This pathway requires and is initiated by the Activation Induced Deaminase (AID) protein, which deaminates cytidine to produce uracils and UG mismatches at the Ig genes. Subsequent processing of uracil by mismatch repair and base excision repair factors contributes to mutagenesis. While selective for certain genomic targets, the chromatin modifications which distinguish hypermutating from non-hypermutating loci are not defined. Methodology/Principal Findings: Here, we show that AID-targeted loci in mammalian B cells contain ubiquitinated chromatin. Chromatin immunoprecipitation (ChIP) analysis of a constitutively ...
