Hayward, Christopher S., Wally V. Kalnins, and Raymond P. Kelly. Acute effects of 17b-estradiol on ventricular and vascular hemodynamics in postmenopausal women. Am J Physiol Heart Circ Physiol 279: H2277–H2284, 2000.—Because premenopausal women have lower cardiovascular morbidity than postmenopausal women, it has been proposed that estrogen may have a protective role. Estrogen is involved in s...

BACKGROUND The metabolic syndrome (MS) represents a cluster of cardiovascular risk factors that act synergistically. OBJECTIVE The aim of this study was to determine which parameters were independently associated with the global left ventricular (LV) function in subjects with MS estimated with the Tei index. METHODS The study included 234 subjects with MS and 96 controls adjusted by age. MS...

INTRODUCTION In recent years, epidemiological studies have strongly related obesity with an increased risk of developing postmenopausal breast cancer. The aromatization of fatty tissue increases the levels of estradiol and adiponectin, which is correlated with the body mass index (BMI). It is of interest to investigate the effect of reducing BMI on estradiol, adiponectin, and IGF-1, as reducing...

Method for aerosol refractive index estimation with ground based polarization measurement data is proposed. The proposed method uses a dependency of refractive index on p and s polarized down welling solar diffuse irradiance. It is much easy to measure p and s polarized irradiance on the ground with a portable measuring instrument rather than solar direct, diffuse and aureole measurements. Thro...

BACKGROUND Osteoporosis is a disease that is seen commonly with increasing age. The purpose of this study was to compare the bone quality of pre- and post-menopausal women using the quantitative indices determined by measurements on panoramic radiographs (mental index, inferior and superior panoramic mandibular indices, antegonion index [AGI], and gonion index) and to determine the effects of s...

Acute β-adrenergic blockade increases aortic wave reflection; however, the mechanisms remain unclear. Evidence suggests that β-adrenergic receptor sensitivity in the peripheral vasculature differs between sexes. Therefore, the goal of this study was to examine whether β-adrenergic blockade alters aortic wave reflection to a similar extent in young men and women. In 31 subjects (16 men and 15 wo...

BACKGROUND Morbid obesity is associated with increased estradiol production as a result of aromatase-dependent conversion of testosterone to estradiol. The elevated serum estradiol levels may inhibit pituitary LH secretion to such extent that hypogonadotropic hypogonadism can result. Normalization of the disturbed estradiol-testosterone balance may be beneficial to reverse the adverse effects o...

background: vitamin d in complex with its receptor by regulating gene expression, endometrium immune response and stimulation of endometrium decidualization can be involved in implantation. so, it seems that the amount of vitamin d in follicular fluids (ff) may have an association with art success. objective: first, we intended to investigate the possible association between levels of follicula...
