Photo album, St. Catharines area, ca. 1913-1919.

One hardcover photo album containing black and white photos. Many of the photos were taken in the St. Catharines area. Included are photos of Port Dalhousie, Port Weller, Niagara Falls, Niagara-on-the-Lake and St. Catharines. There are also photos of Braeside, Ont. and the Ottawa valley. Various local landmarks are included, such as the armoury in St. Catharines, Montebello Park, and Martindale pond. Some of the events captured include a train wreck that occurred in St. Catharines in 1914, the visit of the Governor General to St. Catharines in 1914 (featuring the Carnegie library and Post Office and federal building decorated with flags), and an airplane that crashed into a body of water, possibly a plane from an air training camp in Beamsville during World War I. There are also two photos of champion Niagara district basketball teams, possibly taken in the gymnasium building located behind the former St. Catharines Collegiate building (later Robertson School) on Church Street. One photo includes Norman Byrne, Gladys Ansell, Miriam Marshall, Irene Stoter (?), Mildrerd Houston, A. Gardner, and Madeline Jenner. The other photo includes George Moase, W. Bennett, Norman Byrne, Jack Bain, Mr. Brackenbury, Cyril Merriman, Jim Galway, Harry Erskine, and Roy Carpenter.

Cloning of actin genes from a genomic library of the newt, Notophthalmus viridescens

The regenerating urodele limb is a useful model system in which to study, in vivo, the controls of cell proliferation and differentiation. Techniques are available which enable one to experimentally manipulate mitogenic influences upon the blastema, as well the morphogenesis of the regenerating 11mb. Although classical regeneration studies have generated a wealth of knowledge concerning tissue interactions, little 1s known about the process at the level of gene expression. The aim of this project was to clone potentially developmentally regulated genes from a newt genomic library for use in future studies of gene expression during limb regeneration. We decided to clone the cytoskeletal actin gene for the following reasons: 1. its expression reflects the proliferative and differentiatlve states of cells in other systems 2. the high copy number of cytoplasmic actin pseudogenes in other vertebrates and the high degree of evolutionary sequence conservation among actin genes increased the chance of cloning one of the newt cytoplasmic actin genes. 3. Preliminary experiments indicated that a newt actin could probably be identified using an available chick ~-actln gene for a molecular probe. Two independent recombinant phage clones, containing actin homologous inserts, were isolated from a newt genomic library by hybridization with the chick actin probe. Restriction mapping identified actin homologous sequences within the newt DNA inserts which were subcloned into the plasmid pTZ19R. The recombinant plasmids were transformed into the Escherichia coli strain, DHsa. Detailed restriction maps were produced of the 5.7Kb and 3.1Kb newt DNA inserts in the plasmids, designated pTNAl and pTNA2. The short «1.3 Kb) length of the actin homologous sequence in pTNA2 indicated that it was possibly a reverse transcript pseudogene. Problems associated with molecular cloning of DNA sequences from N. viridescens are discussed with respect to the large genome size and abundant highly repetitive DNA sequences.
