Silent echo-planar imaging for auditory FMRI.

Introduction: The effect of the acoustic scanner noise produced by gradient coil switching on the auditory evoked BOLD signal represents a well-known problem in auditory functional MRI (FMRI). In this paper, a new low-noise echo-planar imaging (EPI) sequence is presented that is optimized for auditory FMRI measurements.

Methods: The sequence produces a narrow-band acoustic frequency spectrum by using a sinusoidal readout echo train and a constant phase encoding gradient.

Gene-gene effects on central processing of aversive stimuli.

Emotional reactivity and regulation are fundamental to human behavior. As inter-individual behavioral variation is affected by a multitude of different genes, there is intense interest to investigate gene-gene effects. Functional sequence variation at two genes has been associated with response and resiliency to emotionally unpleasant stimuli.

In a prospective randomized study, the clinical effectiveness of ciprofloxacin at a single dose of 250 mg p.o. was compared with that of two oral doses of 250 mg bid administered for two days in women with urinary tract infection following gynecological procedures.
