The cytotoxic effects of diesel exhaust particles on human pulmonary artery endothelial cells in vitro: role of active oxygen species.
It is suggested that NO is also involved in DEP-extract-mediated cytotoxicity, which was confirmed by direct measurement of NO production. Expand

Diesel exhaust particles at 0.3 mg/m3 significantly decreased prostate and coagulating gland weights, accompanied by a reduction in thymus and adrenal gland weight, and there was a significant rise in the weights of prostate, seminal vesicles, andCoagulating glands in the 3 mg/ m3 DE group. Expand
Estrogenic Activities of Nitrophenols in Diesel Exhaust Particles1
It is demonstrated that PNMC and PNMPP in DEP have estrogenic activity both in vitro and in vivo and might therefore be considered as endocrine-disrupting chemicals. Expand
CO2 solubility and physical properties of N-(2-hydroxyethyl)pyridinium bis(trifluoromethanesulfonyl)amide
Abstract The densities, viscosities, and electrical conductivities of N -(2-hydroxyethyl) pyridinium bis(trifluoromethanesulfonyl)amide ([Py 2OH ][Tf 2 N]) have been measured over the temperature… Expand
Regulation of Follicle-Stimulating Hormone Secretion by Estradiol and Dimeric Inhibins in the Infantile Female Rat1
It is concluded that large antral follicles in the ovary are the primary source of these bioactive inhibins that are secreted in large amounts into the circulation after PND 20 and that inhibin A appears to be the major physiological regulator of FSH secretion at the initiation of this mechanism.

Biochemical studies on strain differences of mice in the susceptibility to nitrogen dioxide.
The results suggest that the protective enzymes and the antioxidants are important factors at defence mechanism in lungs to NO2 and that the intensity of the protective systems in pigmented strains is generally greater than that in albino strains. Expand
Vagal afferent activities corresponding to respiratory cycle in rats.
The single action potential was recorded to determine the pattern of spontaneous vagal afferent activity corresponding to the respiratory cycle of rats, which has been reported only in rabbits. Expand
Exposure of Neonatal Female Rats to p-tert-Octylphenol Disrupts Afternoon Surges of Luteinizing Hormone, Follicle-Stimulating Hormone and Prolactin Secretion, and Interferes with Sexual Receptive…

It is concluded that the exposure of neonatal female rats to higher doses of OP disrupts the cyclic release of LH, FSH, and PRL, and interferes with the display of sexual receptive behavior in adulthood. Expand
Electrocardiographic abnormalities in rats by acute exposure to nitrogen dioxide.
Results suggest that abnormal cardiac function observed during acute exposure to NO2 is attributable to changes in parasympathetic nervous activity and not to elevated NO2- and NO3- concentration in blood. Expand

To clarify the effects of ozone on behavior, drinking activity was observed continuously in animals exposed to ozone at concentrations of 0.2, 0.4, and 0.8 ppm for 1 wk and the suppression of drinking and recovery were dependent on the concentration of ozone. Expand
