Teaching Process Mineralogy in Australia (2004)

Quinton, Stephen, Vaughan, Jeff, Davidson, L., Nemchin, Alex

The increasing complexity of ores processed today necessitates more detailed mineralogical characterisation than in the past. To ensure that metallurgists have the skills and knowledge required for...

A Feasibility Study of Response Techniques for Discharges of Hazardous Chemicals That Disperse through the Water Column. (2002)

Drake,E., Shooter,D., Lyman,W., Davidson,L.

Certain hazardous chemical spills are soluble in water and may persist in the water column for long periods of time. In some cases, adverse environmental impacts of such spills may be ameliorated by...

Gene-targeted deletion and replacement mutations of the T-cell receptor beta-chain enhancer: the role of enhancer elements in controlling V(D)J recombination accessibility.

Bories, J C, Demengeot, J, Davidson, L, Alt, F W

To assess the role of transcriptional enhancers in regulating accessibility of the T-cell receptor beta-chain (TCRbeta) locus, we generated embryonic stem cell lines in which a single allelic copy of...

Activated Ras signals differentiation and expansion of CD4+8+ thymocytes.

Swat, W, Shinkai, Y, Cheng, H L, Davidson, L, Alt, F W

We describe a novel approach to assay the ability of particular gene products to signal transitions in lymphocyte differentiation in vivo. The method involves transfection of test expression...

Function of the pre-T-cell receptor alpha chain in T-cell development and allelic exclusion at the T-cell receptor beta locus.

Xu, Y, Davidson, L, Alt, F W, Baltimore, D

The pre-T-cell receptor, composed of the T-cell receptor (TCR) beta chain (TCRbeta), pre-Talpha (pTalpha) chain, and CD3 molecules, has been postulated to be a transducer of signals during the early...

Bclx regulates the survival of double-positive thymocytes.

Ma, A, Pena, J C, Chang, B, Margosian, E, Davidson, L, Alt, F W, ...

The bclx gene has been shown to regulate programmed cell death in vitro. We now show that Bclx expression increases dramatically when T cells differentiate from CD4- CD8- (double negative) thymocytes...

CD40-deficient mice generated by recombination-activating gene-2-deficient blastocyst complementation.

Castigli, E, Alt, F W, Davidson, L, Bottaro, A, Mizoguchi, E, Bhan, A K, ...

To study the role of B-cell antigen CD40 in immune responses, mouse embryonic stem (ES) cells in which both copies of the gene encoding CD40 had been disrupted by homologous recombination were...

Suppression of diabetes in nonobese diabetic mice by oral administration of porcine insulin.

Zhang, Z J, Davidson, L, Eisenbarth, G, Weiner, H L

Nonobese diabetic (NOD) mice spontaneously develop an autoimmune form of diabetes associated with insulitis. A number of immunomodulatory therapies have been investigated as a treatment for the...

Sequence of ornithine decarboxylase from Lactobacillus sp. strain 30a.

Hackert, M L, Carroll, D W, Davidson, L, Kim, S O, Momany, C, Vaaler, G L, ...

A gene encoding biodegradative ornithine decarboxylase from Lactobacillus sp. strain 30a was isolated from a genomic DNA library and sequenced. Primer extension analysis revealed two transcription...

Purification and properties of L-glutaminase-L-asparaginase from Pseudomonas acidovorans.

Davidson, L, Brear, D R, Wingard, P, Hawkins, J, Kitto, G B

An enzyme that catalyzes the hydrolysis of both glutamine and asparagine has been purified to homogeneity from extracts of Pseudomonas acidovorans. The enzyme having a ratio of glutaminase to...

Mechanisms of convergence and extension by cell intercalation.

Keller, R, Davidson, L, Edlund, A, Elul, T, Ezin, M, Shook, D, ...

The cells of many embryonic tissues actively narrow in one dimension (convergence) and lengthen in the perpendicular dimension (extension). Convergence and extension are ubiquitous and important...
