To further understand the composition of population of parasite in a single host, we analyzed the GP60 gene of Cryptosporidium parvum amplified from DNA of a randomly selected isolate found in the feces of a diarrheic calf from a dairy farm in Central Chile. Direct sequencing of the amplicon yield the IIaA17G4R1 C. parvum subtype. The same amplicon was(More)
This study examined the effects of music genre and tempo on brain activation patterns in 10 non-musicians. Two genres (rock and jazz) and three tempos (slowed, medium/normal, and quickened) were examined using EEG recording and analyzed through Fast Fourier Transform (FFT) analysis.
