We previously reported that exposure to low (22.5+/-0.2 nm in diameter, 15.4+/-1.0 microg/m(3) in mass weight, 2.27x10(5)/cm(3) in mean number concentration), and medium (26.1+/-0.5 nm, 36.4+/-1.2 microg/m(3), 5.11x10(5)/cm(3)) concentrations of nanoparticle-rich diesel exhaust (NR-DE) for 1 and 2 months (5 h/day, 5 days/week) significantly increased plasma testosterone in male Fischer 344 rats, whereas exposure to a high concentration (27.1+/-0.5 nm, 168.8+/-2.7 microg/m(3), 1.36x10(6)/cm(3… Expand
Effect of nanoparticle-rich diesel exhaust on testosterone biosynthesis in adult male mice
The effect of nanoparticle-rich diesel exhaust (NR-DE) on the testicular function and factors related with the biosynthesis of testosterone gene expression were investigated in mice. Male C57BL/JclExpand
Effect of nanoparticle-rich diesel exhaust on testicular and hippocampus steroidogenesis in male rats
TLDR
NR-DE may influence steroidogenic enzymes in the testis, but not those in the hippocampus, while no significant difference was observed in the steroidogenesis between fresh air exposure and any exposure to NR-DE or F-DE. Expand
Nanoparticle‐rich diesel exhaust‐induced liver damage via inhibited transactivation of peroxisome proliferator‐activated receptor alpha
TLDR
NR‐DE may contain some materials that inhibit PPARα activation in relation to lipid metabolism and inflammation, and exposure at one month may cause inflammation; however, this finding may not be observed after a longer exposure period. Expand
4-Nitro-3-phenylphenol has both androgenic and anti-androgenic-like effects in rats
TLDR
It can be concluded that that PNMPP might have both androgen agonist action by decreasing FSH and LH production in the pituitary and anti-androgenic action by increasing testosterone production from the Leydig cell. Expand
Effects of Exposure to Nanoparticle-rich Diesel Exhaust on Pregnancy in Rats
TLDR
It is demonstrated that exposure of pregnant rats to NR-DE and F-DE suppresses the function of corpora lutea and stimulates thefunction of the adrenal cortex, suggesting a risk of spontaneous abortion associated with maternal hormonal changes. Expand
Ammonium perfluorooctanoate may cause testosterone reduction by adversely affecting testis in relation to PPARα.
TLDR
It is suggested that APFO may disrupt testosterone biosynthesis by lowering the delivery of cholesterol into the mitochondria and decreasing the conversion of cholesterol to pregnenolone and androstandione in the testis of mPPAR α and hPPARα mice, which may, in part, be related to APFO-induced mitochondrial damage. Expand
Exposure to DEHP decreased four fatty acid levels in plasma of prepartum mice.
TLDR
Plasma levels of many FAs were higher in pregnant mice than in postpartum ones in a genotype-independent manner, while it was lower in the livers of fetuses than pups, and DEHP exposure decreased these specific FA concentrations only in mPPARα mice, similarly to triglyceride levels. Expand
Abnormalities in the male reproductive system after exposure to diesel and biodiesel blend
TLDR
Exposure of mice to inhalable BD50 caused more pronounced adverse effects on male reproductive function than diesel, and significant differences in the level of oxidative stress assessed were detected on exposure to respirable BD50 and D100. Expand
Can nanomaterials induce reproductive toxicity in male mammals? A historical and critical review.
TLDR
The NM exposure induces bioaccumulation and toxic effects on male reproductive system of mammal models, confirming its potential risk to human and environmental health and contributes to safety and sustainable use of nanotechnology. Expand
Hepatic peroxisome proliferator-activated receptor α may have an important role in the toxic effects of di(2-ethylhexyl)phthalate on offspring of mice.
TLDR
Taking together, PPARα expression is required for the toxicity of DEHP in fetuses and pups and altered plasma triglyceride levels, through regulation of MTP may be important in mPPARα mice and not in hPPAR α mice. Expand

Effects of inhaled nanoparticle-rich diesel exhaust on regulation of testicular function in adult male rats
TLDR
It is suggested that NR-DE inhalation disrupts the endocrine activity of the male reproductive system and increases testicular ir-inhibin concentrations, but only at 4 weeks. Expand
DIESEL EXHAUST (DE) AFFECTS THE REGULATION OF TESTICULAR FUNCTION IN MALE FISCHER 344 RATS
TLDR
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
Exposure to diesel exhaust affects the male reproductive system of mice.
TLDR
It is proposed here that diesel exhaust is an environmental pollutant with the potential to influence male reproductive function and a no-observed-adverse-effect level (NOAEL) was observed with approximately 30 micrograms DEP/m3, which is lower than the WHO-recommended limit. Expand
Inhalation of diesel engine exhaust affects spermatogenesis in growing male rats.
TLDR
It is suggested that diesel exhaust stimulates hormonal secretion of the adrenal cortex, depresses gonadotropin-releasing-hormone, and inhibits spermatogenesis in rats, and the gaseous phase of the exhaust appears to be more responsible than particulate matter for disrupting the endocrine system.

Elemental composition and sources of fine and ultrafine ambient particles in Erfurt, Germany.
TLDR
The strong correlation of particle number concentrations with NO, which is considered to be typically emitted by traffic, and the striking similarity of their diurnal variation suggest that a sizable fraction of the particle number concentration is associated with emission from vehicles. Expand
Effects of insulin-like growth factor I on steroidogenic enzyme expression levels in mouse leydig cells.
TLDR
Results show that in the absence of IGF-I, there is a failure of adult Leydig cells to mature, and that the reduced capacity for T production is caused by disproportionate expression of T biosynthetic and metabolizing enzymes. Expand
Effects of chronic ethanol on growth hormone secretion and hepatic cytochrome P450 isozymes of the rat.
TLDR
The results suggest that the reduced CYP 2C11 activities, apoprotein levels and steady-state mRNA levels during chronic alcohol exposure are causally related to the alterations in GH secretion. Expand

TLDR
CDNP can be seen as a group of particulate toxins unified by a common mechanism of injury and properties of translocation which have the potential to mediate a range of adverse effects in the lungs and other organs and warrant further research. Expand

It is demonstrated that IGF-I enhances Leydig cell steroidogenesis by upregulating hCG-induced StAR gene expression and protein production. Expand
