The aim of this study was to determine the relationship between observed estrous-related behavior, activity clusters (AC; detected by automatic activity monitor), endocrine profiles, and ovulation time. Twenty-one cows in estrus (after 2 cloprostenol treatments, 11d apart) and 12 nonsynchronized cow

The mossy fiber (MF) pathway is critical to hippocampal function and influenced by gonadal hormones. Physiological data are limited, so we asked whether basal transmission and long-term potentiation (LTP) differed in slices of adult male and female rats. The results showed small sex differences in b

Current HIV research.Curr HIV Res.2015 Jan 20. [Epub ahead of print]
The HIV-1 trans-activator of transcription (Tat) protein, interacts with psychostimulants to potentiate cocaine-reward in rodents. Sex steroids may protect against Tat-induced deficits. Female GT-tg transgenic mice conditionally-expressed Tat protein targeted to brain via a doxycycline-dependent, GF

… Background: Expression and the function of genes generating circadian rhythms in the ovary have not been fully examined from proestrous stage to estrous stage in spite of the interest for the involvement of the circadian clock on ovulation. … Results: Coordinated, rhythmic expression was found for main circadian regulatory genes, suggesting that the ovarian circadian clock is functional from proestrous to estrous stage. …
