Two experiments investigated Zajone's (1968) hypothesis that mere repeated exposure to stimuli is a sufficient condition to enhance individuals' attitudes toward those stimuli. In the first experiment, no significant differences in preference were obtained following exposure to high- and low-redundancy sequences of nonsense syllables. In the second study, the effects of repeated exposure were m...

Although introns in 5'- and 3'-untranslated regions (UTRs) are found in many protein coding genes, rarely are they considered distinctive entities with specific functions. Indeed, mammalian transcripts with 3'-UTR introns are often assumed nonfunctional because they are subject to elimination by nonsense-mediated decay (NMD). Nonetheless, recent findings indicate that 5'- and 3'-UTR intron stat...

introduction: it has been reported the alkaline response of pancreas to duodenal acidification is partly mediated through duodenal release of h2s, but till now the effect of duodenal acidification on gastric h2s release has not been investigated. therefore, the present study designed to evaluate the effects of duodenal acidification on gastric h2s release and level of mrna expression of cystath...

Introduction: Methamphetamine (MA) acts as a powerful oxidant agent, while Rosmarinic Acid (RA) is an effective herbal antioxidant. Oxidative stress-mediated by MA results in apoptosis, and caspase-3 is one of the critical enzymes in the apoptosis process. MA can epigenetically alter gene regulation. In this paper, to investigate the effects of RA on MA-mediated oxidative stress, changes in the...
