A study was conducted to evaluate the gonad differentiation of juvenile yellow perch (YP, Perca flavencens) and determine the latest labile period related to hormone treatment. Juvenile fish were subjected to two dietary concentrations of methyltestosterone (MT; 20 and 50 mg/kg feed) for 60 days in three (3) age groups of 38-, 46-, and 67-days post-hatching (dph), where control group were fed with standard commercial feed. Following a 10-month on-growing period, sex phenotypes were determined by gross and histological gonad morphology.

Article Synopsis
- The study aimed to assess the vestibular function of Chinese astronaut candidates to identify those with optimal vestibular performance.
- The assessment involved 59 male pilot candidates, utilizing various tests including Caloric tests, parallel swing, and Coriolis acceleration stimuli, to evaluate factors like reflex symptoms and balance abilities.
- Results showed that a majority of the candidates displayed normal vestibular function, with over 52% categorized as stability type, suggesting that candidates with stable or relatively stable vestibular function could be selected for space missions.
