introduction: spinal cord injuries are accompanied with significant demyelination of axons and subsequent locomotor dysfunction. to identify the extent of damage following electrolytic lesion of ventrolateral white matter, essential area for initiation of locomotor activity, we assessed demyelination as well as alteration in motor performance. moreover, the protective effect of estradiol as a c...
The ability to maintain and study human tissues in in-vivo environment has proved to be a valuable tool in breast cancer research for several decades. The most widely tissues have been xenografts established human breast cancer cell lines into athymic nude mice. The aim of this study was to provide a new accurate and affordable method for the establishment of breast cancer xenograftin nude mice...
Introduction: 17β-Estradiol is a neuroactive steroid and its pain modulatory role has been well studied previously. 17β-Estradiol modulates nociception by binding to its receptors and also by allosteric interaction with other membrane - bound receptors such as glutamate and GABAA receptors. Paragigantocellularis lateralis (LPGi) is also involved in pain modulation and perception, in addition...
Background and Objectives: This study was conducted to investigate the protective effect of hydroethanolic extract of Lippia citrodora L. leaf (LCE) and vitamin D3 on polycystic ovary syndrome (PCOS) in suri rats. Methods: This experimental study was performed on 48 female suri rats with a weight range of 25-35g. The subjects were divided into 8 groups (n=6 each), namely control (food + wate...
Introduction: 17&beta-Estradiol modulates nociception by binding to the estrogenic receptors and also by allosteric interaction with other membrane-bound receptors like glutamate and GABAA receptors. In addition to its autonomic functions, paragigantocellularis lateralis (LPGi) is involved in the pain modulation, too. The aim of the current study was to investigate the involvement of the membra...
introduction: sexhormones are one of most important factors in difference of learning and memory between tow sexes (male & female). high concentration of estrogen and androgen receptors and mechanism of testosterone and estrogen production in learning and memory center, especially in hippocampus show the role of this receptors, sexhormons and p450 enzymes in spatial memory. consequently, in thi...
for the present study, and follow-up of histochemical changes in estradiol valerate-induced polycysticovary syndrome (pcos), 48 virgin 90-day-old female rats were used. the rats were divided into thetreatment and control groups. for each rat of the treatment group, 4 mg estradiol valerate was injectedthrough intramuscular route for the induction of pcos. the control group was taken the same amo...
The binding of estradiol to uterine cytosoluble receptors from 24-day-old rats was reduced or potentiated by unsaturated fatty acids (NEFAs), depending on the concentrations of estradiol and unsaturated NEFAs. At estradiol concentrations of up to 1.5 x 10(-8) M, unsaturated NEFAs inhibited estradiol binding to the 8 S cytosol receptor. This inhibition was dose-dependent (10-70%, p less than 0.0...
17β-Estradiol is the most potent natural estrogen commonly found in anthropogenically altered environments and has been the focus of many toxicological laboratory studies. However, fewer aquatic toxicological data on the effects of 17α-estradiol, a diastereoisomer of 17β-estradiol, exists in the literature even though it has been found in the aquatic environment, sometimes at higher concentrati...
