2007 article

Acute adverse effects of the indenopyridine CDB-4022 on the ultrastructure of Sertoli cells, spermatocytes, and spermiatids in rat testes: Comparison to the known Sertoli cell toxicant di-n-pentylphthalate DPP

JOURNAL OF ANDROLOGY, Vol. 28, pp. 621–629.

By: S. Hild*, J. Reel*, M. Dykstra n, P. Mann* & G. Marshall*

author keywords: antifertility; morphology; ultrastructure; seminiferous; epithelium; germ cells
MeSH headings : Animals; Indenes / toxicity; Male; Phthalic Acids / toxicity; Piperidines / toxicity; Rats; Rats, Sprague-Dawley; Sertoli Cells / drug effects; Sertoli Cells / pathology; Sertoli Cells / ultrastructure; Spermatids / drug effects; Spermatids / pathology; Spermatids / ultrastructure; Spermatocytes / drug effects; Spermatocytes / pathology; Spermatocytes / ultrastructure; Testis / drug effects; Testis / pathology
TL;DR: The antispermatogenic activity of CDB-4022 appears to be a consequence of direct effects on Sertoli and germ cells. (via Semantic Scholar)

2002 journal article

Suggested Standard Operating Procedures (SOPs) for the preparation of electron microscopy samples for toxicology/pathology studies in a GLP environment

TOXICOLOGIC PATHOLOGY, 30(6), 735–743.

By: M. Dykstra n, P. Mann*, M. Elwell* & S. Ching*

author keywords: sample preparation; TEM; SEM; SOPs
MeSH headings : Animals; Drug Evaluation, Preclinical / standards; Facility Regulation and Control / legislation & jurisprudence; Facility Regulation and Control / standards; Health Policy; Laboratories / legislation & jurisprudence; Laboratories / standards; Microscopy, Electron, Scanning / standards; Quality Assurance, Health Care; Rats; Specimen Handling / standards; Toxicity Tests / standards; United States
TL;DR: A set of Standard Operating Procedures for preparing samples for electron microscopic evaluation that allow storage of samples in the primary fixative for at least 17 years without noticeable degradation, do not compromise the ability to prepare the same samples for standard light microscopic evaluation, and provide tips for orientation of samples that may be necessary for evaluation are provided.

2000 journal article

Cellular and molecular mechanisms of action of linuron: An antiandrogenic herbicide that produces reproductive malformations in male rats

TOXICOLOGICAL SCIENCES, 56(2), 389–399.

By: C. Lambright*, J. Ostby, K. Bobseine, V. Wilson*, A. Hotchkiss*, P. Mann*, L. Gray

author keywords: androgen binding; flutamide; linuron; reproductive malformations; androgen receptor (AR) antagonists
MeSH headings : Abnormalities, Drug-Induced; Androgen Antagonists / toxicity; Animals; COS Cells; Dibutyl Phthalate / toxicity; Dihydrotestosterone / pharmacology; Dose-Response Relationship, Drug; Female; Genitalia, Male / abnormalities; Genitalia, Male / drug effects; Genitalia, Male / pathology; Herbicides / toxicity; Linuron / toxicity; Male; Pregnancy; Rats; Rats, Sprague-Dawley; Transcriptional Activation / drug effects
TL;DR: The hypothesis that linuron is an AR antagonist both in vivo and in vitro is supported, but it remains to be determined if linuron alters sexual differentiation by additional mechanisms of action. (via Semantic Scholar)
