Relative to males, female rats can show enhanced contextual fear generalization (demonstrating a fear response in a safe or neutral context) dependent on estrogen receptor activation. The current experiment aimed to extend this finding to cued fear conditioning. Females in low-estrogen phases of the estrous cycle showed good discrimination,…

Previously most studies indicated that high intensity training is a powerful stimulus to acute increases in blood testosterone hormone levels in males. The testosterone responses to exercise in females are controversial; while some studies have shown increases, others have suggested no change. The aim of this study was to determine alterations in…

Purpose: The purpose of this tutorial is to summarize how sex hormones affect both laryngeal senescence and neuromuscular response to exercise, highlighting the importance of considering sex differences in developing treatment for the senescent voice. Conclusion: Men and women's voices are sexually dimorphic throughout the life span, including…

Kickbox is one of the modern martial sports. The psychophysiological demands of a kickbox competition require that athletes achieve high thresholds in various aspects of physical fitness. The aim of this study is to analyze and evaluate the physiological properties of kickbox athletes and the activity profile properly in order to put forward…

Ample evidence has demonstrated that sex steroid hormones, such as the potent estrogen 17ß-estradiol (E[subscript 2]), affect hippocampal morphology, plasticity, and memory in male and female rodents. Yet relatively few investigators who work with male subjects consider the effects of these hormones on learning and memory. This review describes…

The elevated serum glutamic-oxaloacetic transaminase (GOT) and glutamic-pyruvic transaminase (GPT) rate among people with intellectual disabilities (ID) is unknown and have not been sufficiently studies. The present paper aims to provide the profile of GOT and GPT, and their associated relationship with other biochemical levels of children or…

Animal studies provided evidence that stress modulates multiple memory systems, favoring caudate nucleus-based "habit" memory over hippocampus-based "cognitive" memory. However, effects of stress on learning strategy and memory consolidation were not differentiated. We specifically address the effects of psychosocial stress on the applied learning…
