Introduction: This article describes the invention of graphene oxide (GO) or reduced graphene oxide (rGO) functionalised with 2-methoxy estradiol. The presence of polar hydroxyl groups enables the binding of 2-ME to GO/rGO through hydrogen bonds with epoxy and hydroxyl groups located on the surface and carbonyl and carboxyl groups located at the edges of graphene flake sheets.
Methods: The patented method of producing the subject of the invention and the research results regarding its anticancer effectiveness via cytotoxicity in an in vivo model (against A375 melanoma and 143B osteosarcoma cells) are described.

Soy extract waste, okara, is a rich source of bioactive compounds such as isoflavones, which are phytoestrogens with potential health benefits. To develop a green approach to recovering these compounds and valorizing okara, a study was developed to screen variables for the extraction of isoflavones from okara and soybean (for comparison) using Deep Eutectic Solvents (DES) composed with choline chloride ([Ch]Cl) and acetic acid (AA) ([Ch]Cl: AA, 1:2). A fractional design (2) was used to evaluate variables in the extraction of isoflavones, followed by a Central Composite Rotatable Design (CCRD).

The repercussions of hormone replacement therapy (HRT) and bisphosphonates pose serious clinical challenges and warrant novel therapies for osteoporosis in menopausal women. To confront this issue, the present research aimed to design and fabricate daidzein (DZ); a phytoestrogen-loaded hydroxyapatite nanoparticles to mimic and compensate for synthetic estrogens and biomineralization. Hypothesizing this bimodal approach, hydroxyapatite nanoparticles (HAPNPs) were synthesized using the chemical-precipitation method followed by drug loading (DZHAPNPs) via sorption.

Bisphenol A (BPA), an endocrine-disrupting chemical, is increasingly linked to the pathogenesis of autism spectrum disorder (ASD). This study investigates the effects of prenatal BPA exposure on neural stem cells (NSCs) from the hippocampi of rat offspring, a brain region critical for neurodevelopment and implicated in ASD. Pregnant rats were administered with BPA or vehicle control once daily via oral gavage from gestational day 1 until parturition.

The essential cause of menopause is ovarian failure, which can cause decline in sex hormones (especially estrogen) that can increase the risk of metabolic diseases, such as cardiovascular disease and osteoporosis. This study screened 1511 eligible patients from 2148 perimenopausal and postmenopausal women, measuring various physiological and biochemical indicators to analyze differences among age groups (40-44, 45-49, and 50-54 years) with laboratory techniques. The study found no significant difference in the incidence of cardiovascular disease betweenperimenopausal and postmenopausal women.
