Hereditary tyrosinemia type 1 (HT1) is a severe autosomal recessive metabolic disease associated with point mutations in the human fumarylacetoacetate hydrolase ( FAH ) gene that disrupt tyrosine catabolism. An acute form of HT1 results in death duri

The unscheduled DNA synthesis (UDS) assay measures DNA repair in response to DNA damage. To date, 59 chemicals plus UV and X rays have been tested for UDS in spermatogenic cells of humans, rabbits, rats, and mice. In vivo, in vitro, and combined in v

An autoradiographic procedure was used to measure unscheduled DNA synthesis (UDS, DNA repair synthesis) in spermatogonial and postspermatogonial cell stages of mice after treatment with two doses of N-ethyl-N-nitrosourea (ENU) and N-methyl-N-nitrosou

For approximately thirty years, the facilities at Rocky Mountain Arsenal were used for producing, packaging, and shipping sulfur- and phosphorus-containing mustard, Sarin, and pesticides. Degradation and manufacturing by-products related to these spe

The half‐life of di‐isopropyl methylphosphonate (DIMP) in ground water at 10°C was estimated to be 500 years with a 95% confidence interval of 447 to 559 years from measurements of the hydrolysis rates at four temperatures ranging between 70 and

This report describes a model for producing quantitative genetic risk assessments for human populations. The model is patterned after current methods used in cancer risk analysis. The risk to humans is expressed as the number of additional dominant g

The extent and persistence of DMA damage and repair were investigated in mouse spermatogenic cells exposed in vivo to urethane (ethyl carbamate, EC). Adult male mice exposed to [3H]EC at 10–1,000 mg/kg were sacrificed 12 hr later. EC/metabolite bin

Male mice were exposed to [3H]EtO by inhalation at different exposure rates (300 parts per million (ppm) of EtO for 1 h: 150 ppm for 2 h: 75 ppm for 4 h). The total exposure was fixed at 300 ppm-h. The amount of EtO binding to developing spermatogeni

Objective—To determine whether clinically effective concentrations of methylprednisolone or triamcinolone can be achieved in the navicular bursa after injection of methylprednisolone acetate (MPA) or triamcinolone acetonide (TA) into the distal int
