NCT06771583
This research is being done to examine epigenetic markers and mood changes across the menstrual cycle, particularly in premenstrual dysphoric disorder (PMDD). The investigators previously identified epigenetic biomarkers of postpartum depression, another reproductive affective disorder, and in this study aim to determine if these biomarkers also distinguish PMDD cases from healthy controls at different points in the menstrual cycle. By collecting biological samples (such as blood) and monitoring mood changes across the menstrual cycle, the investigators will be able to determine whether these epigenetic markers are associated with PMDD. The investigators plan to study these epigenetic markers during the follicular phase (roughly the first half of the menstrual cycle, from menses until ovulation) and the luteal phase (roughly the second half of the menstrual cycle, from ovulation to menses). The investigators will study this in two groups: 1) individuals who do NOT have premenstrual mood symptoms, and 2) individuals with premenstrual syndrome/premenstrual dysphoric disorder (PMS/PMDD). The results will provide a comprehensive view of the changes in these systems across the menstrual cycle. This will add to the investigators understanding of the mechanisms that may cause PMS/PMDD.

Conventional alginate impressions are still a burden to both the patient and the operator especially in extraoral maxillofacial rehabilitations cases. Nowadays face scanners are becoming more popular with their increased accuracy in taking facial scans, facilitating the digital workflow. This study will be done to investigate the accuracy of three different face scanning techniques; stationary, handheld and mobile application techniques. A number of sixty volunteers will be recruited. Conventional facial impressions will be made for each participant and the resulting casts will be desktop scanned to act as the control group. Three face scanning techniques will be used for each participant; stationary (Ray face scanner), handheld (Shining 3d face scanner) and mobile phone applications (Heges; Maerk Simonik). The STL files will be compared to that of the control group for comparison of accuracy in the terms of Trueness and Precision.
