Sertoli cells are essential for testicular germ cell maintenance and survival. We made the unexpected observation that x-radiation (x-ray)-induced germ cell loss is attenuated by co-exposure with the Sertoli cell toxicant 2,5-hexanedione (HD). The mechanisms underlying this attenuation of germ

2,5-Hexanedione (2,5-HD) is the most important metabolite of n-hexane and methyl ethyl ketone in human urine. Urinary 2,5-HD is used as a biomarker for biological monitoring of workers exposed to n-hexane. A simple method using headspace solid-phase microextraction (HS-SPME) and

The enantiopure (2S,5S)-hexanediol serves as a versatile building block for the production of various fine chemicals and pharmaceuticals. For industrial and commercial scale, the diol is currently obtained through bakers' yeast-mediated reduction of 2,5-hexanedione. However, this process suffers from its

2,5-Hexanedione (HD), a metabolite of n-hexane, causes central and peripheral neuropathy leading to motor neuron deficits. Although chronic exposure to n-hexane is known to cause gradual sensorimotor neuropathy, there are no reports on the effects of low doses of HD

Germ cell apoptosis directly induced by x-radiation (x-ray) exposure is stage specific, with a higher incidence in stage II/III seminiferous tubules. A priming exposure to the Sertoli cell toxicant 2,5-hexanedione (HD) results in a marked reduction in x-ray-induced germ cell
