In order to determine the developmental potential ofadult marrow-derived progenitor cells, I have isolated, cloned,expanded, and tested the differentiation potential of these cellsin vivo and in vitro. To obtain sufficient cell numbers, I haveused marrow cells from a transgenic mouse(H-2K{dollar}{bsol}sp{lcub}{bsol}rm b{rcub}{dollar}-tsA58)containing a gene construct that promotes cell growth underspecific culture conditions. Each cell from this transgenicmouse, termed "immortomouse", ...

The sarcomeric myosin heavy-chain (sMHC) gene ofDrosophila is single-copy; and RNA transcription from this geneis developmentally regulated. Numerous sMHC mRNAs that differ inexon composition can be formed by alternate RNA processing. Thesetranscriptional events result in the presence of multiple sMHCisoforms in the developing organism. I have characterized twoantibodies which are specific for different types of sMHC proteinisoforms in Drosophila; and investigated the tissue distributionand func...

"Straight Talk" asks: how is heterosexualityconstituted? How, precisely, are subjects produced aspresumptively heterosexual? And where might one locate agency inthis production? Enabled by feminist theory and queer theory,which have so successfully analyzed gender and homosexuality,this study articulates a theory of heterosexuality as "scripted"in the interplay between psychic structures and socialstructures. "Straight Talk" reads the feminist postmodernfictions of ...

Herman Melville s Moby-Dick: or, The Whale has been atthe center of the American Literature canon since the 1920s, whencritical work on his biography and artistry began in earnest.Since then, the plot of the novel has woven its way into popularculture: Captain Ahab and the hunt for the White Whale continueto spark adaptations, reworkings, and allusions, while theopening line, "Call me Ishmael," remains one of the mostwell-known first words in fiction. However, Ishmael both asnarrator a...

The Ni(0) catalyzed cross-coupling reactions of arylmesylates with various organometallic carbanion synthons(organotin, -magnesium and -zinc compounds) are also described.It is demonstrated that Stille-type coupling reaction based onorganotin compounds results in low yields. Good to high yields ofcross-coupled products are obtained by using more reactiveorganomagnesium and-zinc compounds as coupling partners. TheNi(0) catalyzed aromatic nucleophilic substitution reaction ofaryl mesylates with he...

The nonlinear hysteresis loop of asimple-cylindrical-journal-bearing supported rotordynamic systemis characterized by the Hopf-bifurcation and Saddle-Nodebifurcation speeds. The nonlinearity of this system occurs in thejournal-bearing fluid-film forces, and requires the imbedding ofa solution for the Reynolds lubrication education within anumerical integration scheme of the coupled motion equations inorder to perform proper simulations. These show that under alight bearing static load, the Saddl...

Because of its relevance to fracture of compositematerials, the problem of calculating the stress field at the tipof a crack perpendicular to the perfectly bonded interfacebetween two isotropic half-planes has been addressed by severalauthors. However, to date a sound propagation criterion forcracks terminating at a bimaterial interface has not beenproposed. The main purpose of this work is to provide suchpropagation criterion in terms of the physical parameters thatcontrol the inelastic deforma...

We measured the third-harmonic spectrum for lowconcentrations of each of four squaraine dyes in chloroform. Byfitting the experimental dispersion of the third ordersusceptibility, {dollar}{bsol}gamma{dollar}, to a four-levelsum-over-states model, we determine the strength and location ofthe lowest lying two-photon transition.

Information Systems research usually suggests thatinformation received from multiple modalities results in bettercommunication. Media richness theory, for instance, suggests thatone of the reasons face to face communication is better than aletter or memo is the greater number of cues and channels used.However, using auditory and visual channels to presentinformation in multimedia does not always provide benefits. Whenthe information from both channels represents common information,the result is ...

The Bcl-2 oncogene encodes a protein that inhibitsapoptosis or programmed cell death. Apoptosis is a processcritical for development and tissue homeostasis and is of greatimportance to cancer chemotherapy. The molecular mechanisms ofapoptosis are still poorly understood, but it is known that anumber of events occur on mitochondria such as membranepermeabilization and release of intermembrane space proteins intothe cytoplasm. These mitochondrial events are regulated by theBcl-2 family of proteins...

Propagation of transmissible spongiformencephalopathies is believed to involve the conversion of thecellular prion protein, PrPC, into a misfolded oligomericform,PrPSc. An important step towards understanding the mechanismof this conversion is to study the folding pathway(s) and thestability of PrPC. In the first part of this work, we examinedthe kinetics of folding and unfolding reactions for therecombinant wild type human prion protein fragment 90

In many motor-system neuroprostheses, the stimulationtargets are the last order neurons (motoneurons), i.e., theneurons that excite directly the target muscle. The nextgeneration of neural prostheses will likely target existingneural circuitry rather than motoneurons, and we are interestedin the activation of spinal circuits via microstimulation.However, detailed maps of the function and location ofinterneurons of the spinal cord do not exist, and it is not clearwhere electrodes should be placed...

Because fatigue crack growth in a threaded fastener cancause the loss of an aircraft, damage tolerant analyses arerequired. Therefore, aerospace designers must be able to performaccurate crack growth analyses on fasteners. However, threadedfasteners are difficult to analyze and fastener fatigue crackgrowth data is scant, especially for non-dimensionalized crackdepths of (a/d) < 0.1. The objective of this research is todetermine the stress intensity multiplication factor (Y), as afunction ...

Reperfusion of an ischemic myocardium is associatedwith a number of deleterious events that are thought tocontribute to myocardial dysfunction. Cellular events thatpredominate during reperfusion include calcium overload,mitochondrial dysfunction and enhanced production of freeradicals. Cardiac mitochondria are believed to play an importantrole in the pathophysiology of reperfusion by contributing tocalcium overload as well as free radical production. In aninitial in vivo study, the effect of in ...

The fact that an achievement gap between White andAfrican- American students exists is undisputed. The reasons forthis gap are many and complex. Evidence does exist, though, thatthis gap can be narrowed and potentially eliminated. Evidencealso exists that demonstrates that when the gap in academicachievement becomes equal African-Americans are more likely tocomplete college and earn nearly the same income as Whites.Educators must understand the many reasons for the achievementgap and find ways t...
