Ech inhibits oxidative stress by improving antioxidant levels, including glutathione, catalase, and glutathione-S-transferase, with a concomitant decrease in the amounts of malondialdehyde and nitric oxide in kidney and liver tissues. Moreover, it reduced blood concentrations of aspartate aminotransferase, alanine aminotransferase, gamma-glutamyltransferase, alkaline phosphatase, serum urea, uric acid, and creatinine.

Not only tightly bound as structural component and co-factor of more than 3000 proteins, but also as labile bound zinc, so-called mobile Zn (<em>mZn)</em>. This <em>mZn</em> occurs especially in the central nervous system, where it plays a fundamental role in signal transduction. Accordingly, dysregulated zinc homeostasis is linked to the pathogenesis of neurodegenerative diseases. Fluorescence sensors have emerged as powerful tools to unravel its role on the molecular level. With 20 members, the most prominent sensor family is the ZinPyr family that exploits a fluorescein platform equipped with usually two bis(2-pyridylmethyl)amine (DPA) as zinc binding units. Within this article, we report four new bright members of the ZinPyr family, ZP1(5-en), ZP1(6-en), ZP1(5-Me₂en), and ZP1(6-Me₂en), which are derived from the known sensors ZP1(5-CO₂H) and ZP1(6-CO₂H).

These properties make the new sensors among the brightest sensors in the ZinPyr family. Live cell imaging demonstrated their ability to detect intracellular zinc with an approximate turn-on of 2–3.

Biologically female women (women) of reproductive age have a higher risk of developing ID due to the increased physiologic demand for iron required to support menstruation and pregnancy. If left untreated, ID can develop into iron deficiency anaemia (IDA), which affects one in three women between the ages of 15–49 years worldwide. Among women of reproductive age, those who are pregnant have the highest risk of developing ID and IDA due to increased iron requirements to support pregnancy and the developing fetus. Despite the high prevalence of ID and IDA, it remains underdiagnosed in reproductive-aged women and current treatment options are not well accepted. There is an urgent need to investigate novel strategies to ensure adequate iron status in women of reproductive age to prevent adverse health problems and promote healthy pregnancies. This review explored the critical role of iron in women's health by examining iron requirements throughout the lifespan, the physiology of iron absorption, factors affecting iron bioavailability, and the causes of ID and IDA. We discuss the limitations of current interventions for ID and IDA, and the need to develop effective and widely acceptable treatments for these conditions, particularly in women of reproductive age. The findings of this review suggest that current interventions for ID and IDA are inadequate and that sex biases exist in the diagnosis and management of ID and IDA in biologically female women.</div></div>","PeriodicalId":49970,"journal":{"name":"Journal of Trace Elements in Medicine and Biology","volume":"90 ","pages":"Article 127684"},"PeriodicalIF":3.6,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144491282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
