What are estrogens?4 answersEstrogens are naturally occurring steroid hormones that play important roles in various physiological activities in the human body, including development, bone density, cardiovascular health, and reproduction. They are the hormones of reproduction in women and have many other important functions in both males and females. Estrogens can undergo significant changes during different phases of life, such as puberty, pregnancy, and menopause/andropause. They can also be found in non-reproductive tissues such as the liver, heart, muscle, bone, and brain. Estrogens and their synthetic mimics are used as therapeutics for various conditions, including cancer, menopausal symptoms, osteoporosis, and prevention of pregnancy. However, estrogens and certain compounds that mimic their activities have also been implicated in the development of endometrial and breast carcinoma, gallbladder disease, and abnormal blood clotting. The pollution of estrogenic compounds in water bodies has also become a concern due to its impact on the aquatic system.

Does HIIT training enhance the production of testosterone in BASKETBALL athletes?

High-Intensity Interval Training (HIIT) has varying effects on testosterone levels based on different studies. Research indicates that HIIT can lead to increased testosterone levels immediately after a single session, followed by a decrease below baseline levels, and a return to baseline after 24 hours. In young women, HIIT was found to decrease testosterone levels and increase estrogen levels, with no significant impact on trophic hormones like Luteinizing hormone and Prolactin. Additionally, in masters athletes, a six-week HIIT program resulted in a small increase in free testosterone levels. However, a study on rats did not show significant alterations in testosterone levels after HIIT training. Therefore, while HIIT may have varying effects on testosterone production in different populations, it is essential to consider individual characteristics and training protocols.Do men die more from severe COVID-19 than women?

Men have been observed to have a higher risk of mortality from severe COVID-19 compared to women. Studies have shown that men with COVID-19 have significantly increased odds of experiencing mortality and critical illness compared to women. Additionally, men were found to have higher risks of hospitalization, ICU admission, and death due to COVID-19, with the disparity in mortality being more pronounced in older age groups. Comorbidities and biomarkers have also been identified as factors influencing COVID-19 severity differently in men and women, with women showing a higher magnitude of risk for certain fatal comorbidities and abnormal biomarkers associated with death. These findings highlight the importance of considering sex differences in COVID-19 outcomes and the need for tailored approaches to mitigate the higher mortality risk observed in men.How does estrogen affect the tumor microenvironment?

Estrogen plays a significant role in shaping the tumor microenvironment (TME) by influencing various components within it. Estrogen can activate proliferative pathways in cancer cells, impact the immune response within the TME, and regulate the immune microenvironment of cancer metastases. Additionally, estrogen can modulate the stromal expression of estrogen receptors, affecting tumor growth and vasculature organization. The effects of estrogen on the TME involve mechanisms such as promoting the accumulation of immunosuppressive cells, altering cytokine expression, and influencing the recruitment and polarization of immune cells. Overall, estrogen's influence on the TME is complex, involving genomic and non-genomic effects that contribute to tumor progression and potentially impact therapeutic strategies targeting the TME.Does menopause increase the risk of developing arthritis?

Menopause is associated with an increased risk of developing arthritis, particularly osteoarthritis and rheumatoid arthritis. During menopause, women experience estrogen deficiency, which accelerates the aging process and contributes to the development of osteoarthritis. Research has shown that early menopause can lead to higher disease activity and worse patient-reported outcomes in rheumatoid arthritis patients, highlighting the impact of estrogen levels on disease severity. Additionally, a study focusing on female reproductive factors found that early menopause and long-term hormone replacement therapy use may increase the risk of developing rheumatoid arthritis. These findings suggest a significant link between menopause and arthritis, emphasizing the importance of understanding hormonal changes in postmenopausal women to manage arthritis symptoms effectively.What are the properties of Licochalcone A in cancer?

Licochalcone A (LicA) exhibits potent anticancer properties in various types of cancer. LicA has been shown to inhibit cell growth, induce cell cycle arrest, promote apoptosis, and reduce migration and invasion in ovarian cancer, renal cell carcinoma (RCC), and other cancer types. It modulates multiple signaling pathways, including EGFR/ERK, PI3K/Akt/mTOR, and JAK2/STAT3, leading to inhibition of proliferation, migration, and invasion of cancer cells. LicA also demonstrates anti-inflammatory effects by suppressing the expression of inflammatory mediators like TNF-α and IL-6. Moreover, LicA creates a tumor preventive environment in breast tissue by upregulating antioxidant genes, downregulating inflammatory pathways, and suppressing proliferation of pre-malignant and malignant cells. These findings highlight LicA's potential as a promising candidate for cancer treatment and prevention.Is 10000 mcg of biotin safe during pregnancy?

A high dose of biotin, such as 10000 mcg (10 mg), during pregnancy may not be safe based on the available research. Studies have shown that an acute dose of biotin in pregnant rats led to fetal resorption and metabolic disturbances, which were partially mitigated by estrogen therapy. On the other hand, a case study involving a woman with holocarboxylase synthetase deficiency (HSD) who took a high pharmacological dose of biotin (100 mg/day) during pregnancy had an uncomplicated childbirth, suggesting safety for the fetus. However, the long-term effects and safety of such high doses on fetal development remain uncertain, emphasizing the need for further research on the maximum acceptable biotin dosage for pregnant women and their fetuses. Therefore, caution is advised when considering high doses of biotin during pregnancy due to the limited data available on its safety.Doxorubicin-loaded PLGA nanoparticles by nanoprecipitation

Male rabbit behavior is characterized by specific patterns related to sexual, social, and territorial interactions. Sexual behavior in male rabbits involves a single mount followed by ejaculation, with changes observed as they age, such as longer inter-ejaculatory intervals and increased "miss rates" over consecutive days of testing. Social and territorial behaviors, like grooming, marking, mounting, and following, influence interferon-gamma production and glucocorticoid receptor activity in peripheral blood mononuclear cells, indicating a link between behavior and immune response. Agonistic behaviors in male rabbits, such as following, attacking, and chasing, are associated with changes in testosterone levels and estradiol binding in the hypothalamus, suggesting a hormonal influence on aggressive behavior. These studies collectively highlight the intricate relationship between behavior, hormonal regulation, and immune function in male rabbits.How estrogen modulate pain transmission?

Estrogen modulates pain transmission through various mechanisms. Studies have highlighted the involvement of estrogen in visceral pain sensitivity. Estrogen can signal through both classical nuclear estrogen receptors (ERα and ERβ) and membrane ERs like GPER1, affecting nociception. At the spinal level, estrogen acutely enhances nociceptive transmission via membrane-bound estrogen receptors, leading to mechanical allodynia and thermal hyperalgesia. Additionally, estrogen influences pain processing peripherally by modulating purinergic and opioid receptors in primary afferent neurons, impacting nociceptive signaling. Furthermore, estrogen's control over peripheral pain signal transduction involves modulating P2X3 receptors in dorsal root ganglion neurons, affecting mechanical hyperalgesia. Overall, estrogen's role in pain modulation encompasses both central and peripheral mechanisms, highlighting its significance in pain sensitivity regulation.What are the potential medicinal properties of Garcinia binucao leaves?
