Estradiol News and Research

RSS

Estradiol is a sex hormone. Mislabelled the "female" hormone, it is also present in males; it represents the major estrogen in humans. Estradiol has not only a critical impact on reproductive and sexual functioning, but also affects other organs including the bones.

Estradiol appears to help in female SARS-CoV-2 infection

A new study published on the preprint server medRxiv in August 2020 shows that the risk of infection is high for pre-menopausal women but the risk of death is much higher for men in the same age group and throws light on the protective nature of estradiol therapy in post-menopausal women.

TGen review: Postmenopausal women at higher risk for developing NALFD

A review article authored by a researcher at the Translational Genomics Research Institute, an affiliate of City of Hope, suggests that following menopause, women are at higher risk for developing nonalcoholic fatty liver disease, a chronic condition caused by the build-up of excess fat in the liver not caused by alcohol.

New studies identify contributors to higher risk of stress fractures in female runners

Running is one of the most popular forms of exercise, enjoyed by a broad range of age groups and skill levels. More women are running recreationally compared to men; specifically 54% of runners are female as indicated by a 2018 National Runner Survey.

Estrogen modestly protective against COVID-19?

Almost from the beginning, scientists have been struck by the disproportionately higher numbers of men and older adults who have developed severe COVID-19 disease compared to younger individuals and women. Prior research has shown that in 37 of the 38 countries from which sex-stratified data was available, males were at a higher risk of death. Also, post-menopausal women are at increased risk of severe COVID-19. However, the biological underpinnings of this have been less visible.

War of sugars - estrogen provides protection in COVID-19

Now a new study published on the preprint server bioRxiv in July 2020 reports that sex hormones could affect the function of the fusion protein that is dependent upon the human ACE2 receptor, thus preventing the entry of the virus into the host cell.

Small molecule drugs binding Mac1 domain of SARS-CoV-2

Now, an intriguing new study out of the University of Wisconsin-Milwaukee reveals that numerous small molecule drugs like the proton pump inhibitors omeprazole and rabeprazole bind the important Mac1 domain on the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus.

Study: Genes may play a far more complex role in oocyte maturation than previously assumed

Over the last six years a group of Estonian geneticists led by Associate Professor Agne Velthut-Meikas and a PhD student Ilmatar Rooda from TalTech Department of Chemistry and Biotechnology have studied genes previously associated primarily with female hormone synthesis and ovarian follicle development.

Menopause age not associated with heart disease finds study

There has been conflicting evidence regarding early menopause and an increased risk for heart disease among women. This connection has been attributed to the lowering of female hormone estrogen levels in the blood.

Scientists develop computationally inspired method for preclinical study of anxiety

Nearly 40 million people in the U.S. have an anxiety disorder. While treatment options exist, treatment success varies, and many people do not respond to treatment until weeks or months after they begin anti-depressants

Lower levels of 'free' testosterone found in women with asthma

Women with asthma appear more likely to have lower levels of "free" (not attached to proteins) testosterone than women who do not have asthma, according to new research published online in the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine.

Higher dosage of statins can increase risk of osteoporosis, shows study

At low doses, statins could protect against bone resorption. But the higher the dosage of cholesterol-lowering drugs, the greater the probability of osteoporosis, an analysis of millions of patient data by the Complexity Science Hub Vienna shows.

Study identifies determinants of estradiol levels among women using hormone therapy

The benefits of hormone therapy on atherosclerosis relates to achieved estradiol levels among those women who initiate HT early in postmenopause. Despite the use of hormones, however, women's estradiol levels are often inconsistent.
