Fast dynamic brain PET imaging using stochastic variational prediction for recurrent frame generation.

Purpose: We assess the performance of a recurrent frame generation algorithm for prediction of late frames from initial frames in dynamic brain PET imaging.

Methods: Clinical dynamic F-DOPA brain PET/CT studies of 46 subjects with ten folds cross-validation were retrospectively employed. A novel stochastic adversarial video prediction model was implemented to predict the last 13 frames (25-90 minutes) from the initial 13 frames (0-25 minutes).

Effect of feeding male mice with palm, fish, and sunflower oils on sperm characteristics and sex ratio of offspring.

Several studies have indicated that feeding female animal with fatty acids could result in alteration of offspring sex ratio; however, there is little information available regarding the effect of feeding male animal with fatty acids on sex ratio of offspring. The aim of current study was to investigate the effect of paternal feeding with n-3 and n-6 polyunsaturated fatty acids (PUFAs) on sperm characteristics and sex ratio of offspring in mice. Male mice received 2.
