The Role of Organizational Climate and Culture in the School Improvement Process: A Review of the Knowledge Base (2006)

Ronald Lindahl

The professional knowledge base is replete with theoretical postulations, research findings, and practitioner reflections on school improvement, school climate, and school culture. However,...

Role of aldehyde metabolizing enzymes in mediating effects of aldehyde products of lipid peroxidation in liver cells (1994)

Canuto, Rosa A., Ferro, Margherita, Muzio, Giuliana, Bassi, Anna M., Leonarduzzi, Gabriella, Maggiora, Marina, ...

It is well established that many types of tumor cells have reduced lipid peroxidation capacity compared to their normal counterparts. Changes in the activity of enzymes metabolizing aldehydes...

Effects of hepatocarinogenic initiators on aldehyde dehydrogenase gene expression in cultured rat hepatic cells (1990)

Huang, Min, Lindahl, Ronald

The effects of certain in vivo inducers of tumor-associated aldehyde dehydrogenase (aldehyde:NAD+ oxidoreductase, EC 1.2.1.3; ALDH) activity on the expression of tumor-associated ALDH (T-ALDH)...

Changes in aldehyde dehydrogenase during rat urinary bladder carcinogenesis (1989)

Campbell, Peggy, Irving, Charles C., Lindahl, Ronald

We have reported that normal rat urinary bladder possesses significant amounts of an aldehyde dehydrogenase (class 3 ALDH) expressed during hepatocarcinogenesis, but not detectable in normal liver....

Changes in aldehyde dehydrogenase activity during diethylnitrosamine-initiated rat hepatocarcinogenesis (1987)

Lindahl, Ronald, Evces, Susan

Diethylnitrosamine following partial hepatectomy followed by phenobarbital promotion was used to study changes in aldehyde dehydrogenase (ALDH) activity during rat hepatocarcinogenesis. Over a period...

Expression of tumor-associated aldehyde dehydrogenase during rat hepatocarcinogenesis using the resistant hepatocyte model (1984)

Jones, David E., Evces, Susan, Lindahl, Ronald

The resistant hepatocyte model was used to study expression of tumor-associated aldehyde dehydrogenase (ALDH) activity during the course of rat hepatocarcinogenesis. The hepatic ALDH phenotype was...

Sequential 2-acetylaminofluorene -- phenobarbital exposure induces a cytosolic aldehyde dehydrogenase during rat hepatocarcinogenesis (1982)

Allen, Bibb, Lindahl, Ronald

A significant change in hepatic aldehyde dehydrogenase activity has been observed in normal Sprague-Dawley rat liver during the promotion phase of hepatocarcinogenesis induced by brief feeding of...

Subcellular distribution and properties of aldehyde dehydrogenase from 2-acetylaminofluorine-induced rat hepatomas

Lindahl, Ronald

The subcellular distribution and properties of four aldehyde dehydrogenase isoenzymes (I-IV) identified in 2-acetylaminofluorene-induced rat hepatomas and three aldehyde dehydrogenases (I-III)...

Aldehyde dehydrogenase in 2-acetaminofluorene-induced rat hepatomas. Ontogeny and evidence that the new isoenzymes are not due to normal gene de-repression

Lindahl, Ronald

The pre- and post-natal ontogeny of Sprague–Dawley rat liver aldehyde dehydrogenase [aldehyde–NAD(P)+ oxidoreductase, EC 1.2.1.5] is described. At no time in its ontogenetic development does...
