Molecular Docking of Abroma augusta Phytocompounds Against Estrogen Receptor Alpha (Er-Α) for the Treatment of Menstrual Disorders
Abstract: Menstrual disorders, including dysmenorrhea (painful menstruation), amenorrhea (absence of menstruation), and irregular menstrual cycles, significantly impact women’s reproductive health and overall well-being. These conditions often arise from hormonal imbalances, inflammation, and uterine dysfunction, necessitating effective therapeutic interventions. Current treatments, such as hormonal therapies (oral contraceptives, progestin-only pills), NSAIDs, and surgical procedures (endometrial ablation, hysterectomy), provide relief but often target symptoms rather than addressing the underlying causes. Consequently, there is a …

AI-Driven Micro-Expression Recognition for Early Mental Health Disorder
Abstract: Mental health conditions like anxiety and depression are often undiagnosed because the usual diagnostic methods based on basic regular instruments like questionnaires and clinical interviews have some limitations in them. They are not objective often and may not catch the initial signs of psychological distress. Micro-expressions have become valid measures of repressed or unconscious emotions and can provide greater insight into someone's mental condition. Also, identification and interpretation of these …
