The measurement of pitch perturbation has been used in acoustic screening for the detection of vocal disorders. As an alternative to applying conventional statistical techniques to the pitch perturbation parameters used for Separation of control and pathological speakers, a parallel distributed processing model approach has been implemented using a Boltzmann Machine (BM). After training, the ma...

The acute and sub-acute toxicity of safranal were studied in rat and mice within 2 and 21 days after exposure, respectively. For subacute toxicity, changes in weight as well as biochemical, hematological and pathological parameters were studied. The intraperitoneal LD50 values of safranal were 1.48 mL/kg in male mice, 1.88 mL/kg in female mice and 1.50 mL/kg in male rats. Oral LD50 values were ...

Background: Glyphosate (GPT) is a broad-spectrum systemic herbicide used to kill weeds, especially annual broadleaf and grasses known to compete with commercial crops grown around the globe. According to United States environmental protection agency the chemical has been reported as a third class toxin. Present study was designed in order to evaluate GPT-induced detrimental effects on testicula...
