… We include both GED and regular school completion as high school graduation. In the NLSY, approximately 6 percent of women completed high school through GED programs, and this …

An analysis of pterosaurian biogeography: implications for the evolutionary history and fossil record quality of the first flying vertebrates.

Historical biology

Upchurch P, Andres B, Butler RJ, Barrett PM.
PMID: 26339122
Hist Biol. 2015 Aug 18;27(6):697-717. doi: 10.1080/08912963.2014.939077. Epub 2015 Jul 28.

The biogeographical history of pterosaurs has received very little treatment. Here, we present the first quantitative analysis of pterosaurian biogeography based on an event-based parsimony method (Treefitter). This approach was applied to a phylogenetic tree comprising the relationships of...

Anthropogenic N Deposition Slows Decay by Favoring Bacterial Metabolism: Insights from Metagenomic Analyses.

Frontiers in microbiology

Freedman ZB, Upchurch RA, Zak DR, Cline LC.
PMID: 26973633
Front Microbiol. 2016 Mar 02;7:259. doi: 10.3389/fmicb.2016.00259. eCollection 2016.

Litter decomposition is an enzymatically-complex process that is mediated by a diverse assemblage of saprophytic microorganisms. It is a globally important biogeochemical process that can be suppressed by anthropogenic N deposition. In a northern hardwood forest ecosystem located in...

Predictors of false lumen thrombosis in type B aortic dissection treated with TEVAR.

Annals of cardiothoracic surgery

Tolenaar JL, Kern JA, Jonker FH, Cherry KJ, Tracci MC, Angle JF, Sabri S, Trimarchi S, Strider D, Alaiwaidi G, Upchurch GR.
PMID: 24967164
Ann Cardiothorac Surg. 2014 May;3(3):255-63. doi: 10.3978/j.issn.2225-319X.2014.05.17.

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) offers a less invasive treatment option in type B aortic dissection (TBAD) patients and its value has been demonstrated in acute and chronic dissection patients. Total false lumen thrombosis (FLT) is associated with...

Prothrombotic Consequences of the Oxidation of Fibrinogen and their Inhibition by Aspirin.

Journal of thrombosis and thrombolysis

Upchurch Jr, Ramdev N, Walsh MT, Loscalzo J.
PMID: 10608044
J Thromb Thrombolysis. 1998;5(1):9-14. doi: 10.1023/a:1008859729045.

Oxidant stress leads to covalent oxidative modification of several plasma proteins, chief among which is fibrinogen. Aspirin can nonenzymatically acetylate fibrinogen's lysine residues, the functional groups most susceptible to oxidative modification. Because oxidation of fibrinogen may occur in the...

Charbeckia macrophylla gen. et sp. nov. from the Lower Mississippian Price (Pocono) Formation of southeastern West Virginia.

Review of palaeobotany and palynology

Knaus MJ, Upchurch GR, Gillespie WH.
PMID: 10936607
Rev Palaeobot Palynol. 2000 Aug 01;111(1):71-92. doi: 10.1016/s0034-6667(00)00018-x.

A fossil plant discovery from the Price (Pocono) Formation of southeastern West Virginia provides new information on the poorly known compression floras of the Lower Mississippian of North America. The new plant described herein consists of long tapering bipinnate...

Isolation of Light-Enhanced cDNAs of Cercospora kikuchii.

Applied and environmental microbiology

Ehrenshaft M, Upchurch RG.
PMID: 16348553
Appl Environ Microbiol. 1991 Sep;57(9):2671-6. doi: 10.1128/aem.57.9.2671-2676.1991.

Cercospora kikuchii is a fungal pathogen of soybeans which produces a photosensitizing phytotoxic polyketide metabolite, cercosporin. Cercosporin synthesis in culture is modulated by several environmental factors. In addition to the light requirement for toxin action, cercosporin biosynthesis is also...

Mutants of Cercospora kikuchii Altered in Cercosporin Synthesis and Pathogenicity.

Applied and environmental microbiology

Upchurch RG, Walker DC, Rollins JA, Ehrenshaft M, Daub ME.
PMID: 16348567
Appl Environ Microbiol. 1991 Oct;57(10):2940-5. doi: 10.1128/aem.57.10.2940-2945.1991.

We have obtained spontaneous and UV-induced stable mutants, altered in the synthesis of cercosporin, of the fungal soybean pathogen Cercospora kikuchii. The mutants were isolated on the basis of colony color on minimal medium. The UV-induced mutants accumulated, at...

Endovascular treatment of aortic aneurysms: state of the art.

Current treatment options in cardiovascular medicine

Eliason JL, Upchurch GR.
PMID: 19289026
Curr Treat Options Cardiovasc Med. 2009 Apr;11(2):136-45. doi: 10.1007/s11936-009-0014-8.

Abdominal aortic aneurysms (AAAs) continue to be a leading cause of death, with increasing incidence and prevalence. Endovascular aneurysm repair (EVAR) now represents the most common method of AAA repair in the United States. Ongoing improvements in endovascular stent-graft...

Second-harmonic generation of a tunable continuous-wave CO2 laser in orientation-patterned GaAs.

Optics letters

Gonzalez LP, Upchurch DC, Schunemann PG, Mohnkern L, Guha S.
PMID: 23381424
Opt Lett. 2013 Feb 01;38(3):320-2. doi: 10.1364/OL.38.000320.

Tunable, mid-infrared radiation was obtained by frequency doubling of a continuous-wave CO(2) laser in orientation-patterned GaAs crystal. Active cooling of the crystal minimized pump-induced thermal effects, allowing generation of output powers exceeding 300 mW across the wavelength range of...
