Long-term depression (LTD) of synaptic efficacy has proven a difficult phenomenon to examine in vivo, despite the ease with which it is induced in a variety of in vitro preparations. Prior exposure to an acute stressful episode does however seem to enhance the capacity of the hippocampus to exhibit LTD in vivo in male animals. In the present experiments, we examined the capacity for low-frequen...

conclusions no interactivity is present in modulatory effects of gabaa receptors and elf-emfs on serum testosterone of male rats. patients and methods fifty adult male rats were randomly assigned into 10 groups. groups 2, 4, 6, 8, and 10 were exposed to elf-emf for 30 days 8hrs per day; while, the remaining groups (1, 3, 5, 7, and 9) were sham exposed animals. at the end of the experiment, anim...

background: acyclovir (acv), a synthetic purine nucleoside analogue, is known to be toxic to gonads. objective: the current study evaluated cytotoxicity of acv on histopathological changes in testis tissue and serum testosterone and lipid peroxidation concentrations of male rats. materials and methods: animals were divided into five groups. one group served as control and one group served as co...

The U.S. National Institutes of Health (NIH) announced last May that steps will be taken to address the over-reliance on male cells and animals in preclinical research. To further address this announcement, in September 2014, scientists with varying perspectives came together at Georgetown University to discuss the following questions. (1) What metrics should the NIH use to assess tangible prog...

Abstract Environmental noise has a significant negative impact on acoustic communication in most situations, as it influences the production, transmission, and reception of signals. However, how animals respond to conspecific sounds when there is interference from environmental noise, whether males females display convergent behavioral responses face masking remain poorly understood. In this st...
