Silbiger R, Leonard A, Dimsoski P, Fore S, Guttman S, Roth A, et al.
Environ Toxicol Chem . 2001 Nov; 20(11):2580-7. PMID: 11699785
Conservation biology needs sound biological information in order to maintain biological diversity in the face of the current rate of loss. An important component of the information needed is the...

Grimwade J, Ryan V, Leonard A
Mol Microbiol . 2000 Feb; 35(4):835-44. PMID: 10692160
In Escherichia coli, initiation of chromosome replication requires that DnaA binds to R boxes (9-mer repeats) in oriC, the unique chromosomal replication origin. At the time of initiation, integration host...

Leonard A, Franson S, Hertzberg V, Smith M, Toth G
Mol Ecol . 2000 Jan; 8(12):2105-14. PMID: 10632861
Multilocus DNA fingerprinting methods have been used extensively to address genetic issues in wildlife populations. Hypotheses concerning population subdivision and differing levels of diversity can be addressed through the use...

Cassler M, Grimwade J, McGarry K, Mott R, Leonard A
Nucleic Acids Res . 1999 Nov; 27(23):4570-6. PMID: 10556312
The nucleoprotein complex formed on oriC, the Escherichia coli replication origin, is dynamic. During the cell cycle, high levels of the initiator DnaA and a bending protein, IHF, bind to...

Helmstetter C, Thornton M, Zhou P, Bogan J, Leonard A, Grimwade J
J Bacteriol . 1997 Feb; 179(4):1393-9. PMID: 9023227
Replication of the miniF plasmid pML31 was examined during the division cycle of Escherichia coli growing with doubling times between 40 and 90 min at 37 degrees C and compared...

Jayatilake G, Thornton M, Leonard A, Grimwade J, Baker B
J Nat Prod . 1996 Mar; 59(3):293-6. PMID: 8882433
In an ongoing survey of the bioactive potential of microorganisms associated with marine invertebrates, the culture media of a sponge-associated bacterial strain of Pseudomonas aeruginosa was found to contain metabolites...

Cassler M, Grimwade J, Leonard A
EMBO J . 1995 Dec; 14(23):5833-41. PMID: 8846776
Initiation of DNA synthesis is triggered by the binding of proteins to replication origins. However, little is known about the order in which specific proteins associate with origin sites during...

Kramer T, Lindy J, Green B, Grace M, Leonard A
Suicide Life Threat Behav . 1994 Jan; 24(1):58-67. PMID: 8203009
Vietnam veterans (N = 232) recruited from three sources were assessed for suicidal thinking and behaviors, and symptoms of posttraumatic stress disorder (PTSD) and depression. Findings support the notion that...

Green B, Grace M, Vary M, Kramer T, GLESER G, Leonard A
J Am Acad Child Adolesc Psychiatry . 1994 Jan; 33(1):71-9. PMID: 8138524
Objective: To conduct a long-term follow-up of child survivors of a devastating human-caused disaster. Method: Child survivors (2-15) of the Buffalo Creek dam collapse, first evaluated in 1974, 2 years...

Mol Microbiol . 1993 Nov; 10(3):575-84. PMID: 7968535
Transcriptional levels of the Escherichia coli mioC and gidA genes, which flank the chromosomal origin of replication (oriC) and the dnaA gene, were correlated with the time of initiation of...
