Environmental Toxicology is the study of the impacts of pollutants/toxicants upon man and animals. It is also the study of natural products of the environment and their use/misuse and impacts/benefits on man and animals. Practical and current topics in toxicology will be integrated into scientific discussions. The topic for this semester is the toxicology and pharmacology of Herbal Products and Dietary Supplements. Use of Natural environmental herbal and dietary supplements have become very popular and are mostly unregulated so can be purchased over the counter. Discussions of promotions of such natural environmental products and environmental legislation pertinent to this area are included in the lectures

Western Iowa Proboscidians

The present paper is a survey of Pleistocene mammoth and mastodon remains from western Iowa. Included are locality data and references to the literature for over 350 specimens from 32 of 41 counties surveyed. Mammoths are found to be more numerous than mastodons, reversing the pattern observed in the woodland areas adjoining the present-day Prairie Peninsula. The first radiocarbon date for the mastodon in Iowa (13,520± 135 B.P.) is reported from Harrison County. None of the localities surveyed have provided any evidence of early man

Dose-dependent effects of a soluble dietary fibre (pectin) on food intake, adiposity, gut hypertrophy and gut satiety hormone secretion in rats

The oral microbiome and adverse pregnancy outcomes.

Significant evidence supports an association between periodontal pathogenic bacteria and preterm birth and preeclampsia. The virulence properties assigned to specific oral pathogenic bacteria, for example, Fusobacterium nucleatum, Porphyromonas gingivalis, Filifactor alocis, Campylobacter rectus, and others, render them as potential collaborators in adverse outcomes of pregnancy. Several pathways have been suggested for this association: 1) hematogenous spread (bacteremia) of periodontal pathogens; 2) hematogenous spread of multiple mediators of inflammation that are generated by the host and/or fetal immune response to pathogenic bacteria; and 3) the possibility of oral microbial pathogen transmission, with subsequent colonization, in the vaginal microbiome resulting from sexual practices. As periodontal disease is, for the most part, preventable, the medical and dental public health communities can address intervention strategies to control oral inflammatory disease, lessen the systemic inflammatory burden, and ultimately reduce the potential for adverse pregnancy outcomes. This article reviews the oral, vaginal, and placental microbiomes, considers their potential impact on preterm labor, and the future research needed to confirm or refute this relationship
