The university's value, we claim, lies in the complex relationship it creates between knowledge, communities, and credentials. Changes contemplated in either the institutional structure or technological infrastructure of the university should recognize this relationship. In particular, any change should seek to improve the ability of students to work(More)
Bisphenol A (BPA) was evaluated at concentrations of 0, 0.015, 0.3, 4.5, 75, 750, and 7500 ppm ( approximately 0.001, 0.02, 0.3, 5, 50, and 500 mg/kg/day of BPA) administered in the diet ad libitum to 30 CD((R)) Sprague-Dawley rats/sex/dose for 3 offspring generations, 1 litter/generation, through F3 adults. Adult systemic toxicity at 750 and 7500 ppm in(More)
Dietary bisphenol A (BPA) was evaluated in a mouse two-generation study at 0, 0.018, 0.18, 1.8, 30, 300, or 3500 ppm (0, 0.003, 0.03, 0.3, 5, 50, or 600 mg BPA/kg/day, 28 per sex per group). A concurrent positive control group of dietary 17beta-estradiol (0.5 ppm; 28 per sex) confirmed the sensitivity of CD-1 mice to an endogenous estrogen. There were no(More)
No information exists on reproductive/developmental effects in mice exposed to dietary 17beta-estradiol (E2) over multiple generations. Therefore, under OECD Test Guideline 416 with enhancements, CD-1 mice (F0 generation, 25 mice/sex/group) were exposed to dietary E2 at 0, 0.001, 0.005, 0.05, 0.15, or 0.5 ppm ( approximately 0, 0.2, 1, 10, 30, or 100 mug(More)
Ketamine is a non-competitive N-methyl D-aspartate (NMDA) receptor antagonist with analgesic and dissociative anesthetic properties. Low dose or sub-anesthetic doses of ketamine have been used effectively as either a primary analgesic or analgesic adjuvant in a variety of pain syndromes. In this paper, three patients with difficult to treat, predominantly(More)
Chemicals, by virtue of their varied interactions with biological molecules, are expected to differ in the way they may alter female reproduction. Reproductive toxicity may reflect effects either on the female germ cells or on various maternal processes such as ovulation, implantation, pregnancy, and parturition. In either case, the ultimate manifestation(More)
Octylphenol (OP) is a commercial intermediate used primarily for the production of octylphenol polyethoxylate surfactants. To determine potential reproductive toxicity of OP, a two-generation reproduction study was conducted according to U.S. EPA OPPTS Guideline 870.3800 (draft 1996). Additional measurements were made on retained F2 offspring. OP was(More)
This study evaluated the potential for dietary para-nonylphenol (NP; CAS No. 84852-15-3) to affect parental fertility and growth and development of three offspring generations in CD (Sprague-Dawley [SD]) rats, including sperm counts across generations to determine the validity of equivocal reductions observed in the F2 generation by R. E. Chapin et al.(More)
Increases in the use of methanol (MeOH) as a transportation fuel would result in greater potential for inhalation exposure. Because oral exposure to MeOH potentiates the hepatotoxicity of carbon tetrachloride (CCl4), we examined the ability of inhaled MeOH to potentiate CCl4 hepatotoxicity and the time course of injury and recovery. Adult male F-344 rats(More)
