Utilization of immunohistochemistry in gynecologic tumors: An expert review.

The use of immunohistochemistry (IHC) and molecular pathology has been widely adopted over the past 3 decades and has aided in the precision of diagnosing gynecologic tumors. While many tumors can be diagnosed by histologic appearance on routine hematoxylin and eosin stained slides, the use of IHC has dramatically changed practice, leading to a better understanding and subtyping of gynecologic tumors. This detailed classification of tumors has aided in the implementation and development of targeted therapies.

Cervical adenocarcinoma presenting as an ovarian torsion.

Background: Cervical adenocarcinoma is increasing in incidence and can rarely present as ovarian metastasis.Case: A 41-year-old female who presented with left lower quadrant pain and vomiting. Intra-operative findings revealed bilateral ovarian cysts with initial pathology results of mucinous ovarian adenocarcinoma.

Engineered transcription-associated Cas9 targeting in eukaryotic cells.

DNA targeting Class 2 CRISPR-Cas effector nucleases, including the well-studied Cas9 proteins, evolved protospacer-adjacent motif (PAM) and guide RNA interactions that sequentially license their binding and cleavage activities at protospacer target sites. Both interactions are nucleic acid sequence specific but function constitutively; thus, they provide intrinsic spatial control over DNA targeting activities but naturally lack temporal control. Here we show that engineered Cas9 fusion proteins which bind to nascent RNAs near a protospacer can facilitate spatiotemporal coupling between transcription and DNA targeting at that protospacer: Transcription-associated Cas9 Targeting (TraCT).

Generation and Maintenance of Patient-Derived Endometrial Cancer Organoids.

Endometrial cancer (EC) is the leading cause of gynecologic cancer morbidity and mortality in the U.S. Despite advancements in cancer research, EC death rates are increasing, particularly high-grade endometrial cancers.

Integrating Formative and Summative Clinical Skills Examinations to Promote Learning for Early Medical Students: A Mixed Methods Study.

Background: Medical educators aim to train students with high-quality clinical skills through the promotion of self-regulated learning and the development of lifelong learning skills. Formative clinical skills examinations (FCSE) allow for real-time learner-centered feedback and coaching which are key in promoting the development of expertise in early learners. This study assessed the impact of the integration of FCSE with learner-centered, real-time feedback and coaching based on an "educational plan-do-study-act" (PDSA) cycle on early medical students' experience and performance.
