Findings from clinical trials have led to advancement of care for patients with gynecologic malignancies. However, restrictive inclusion into has been widely criticized inadequate representation the real-world population. Ideally, enrolled in should represent a broader population enhance external validity and facilitate translation outcomes across all relevant groups. Specifically, there systematic lack data underrepresented groups, many studies failing report or differentiate study...

Abstract Stearoyl-CoA desaturase 1 (SCD1) is an attractive target for cancer therapy. However, the clinical efficacy of SCD1 inhibitor monotherapy limited. There thus a need to elucidate mechanisms resistance inhibition and develop new therapeutic strategies combination In this study, we investigated molecular by which cells acquire endoplasmic reticulum (ER) stress-dependent cell death induced inhibition. inhibitor-sensitive -resistant were treated with inhibitors in vitro, accumulated...

Abstract Objectives: The initial learning curve is a barrier to introducing robotic surgery. Evidence regarding appropriate simulation programs that allow for smooth introduction of gynecological surgery remains limited. Materials and Methods: We retrospectively analyzed 149 patients who underwent gynecologic diseases. Before their first procedure, the surgeons completed training program. Assistant also programs, including setup procedures manipulation arm. Results: mean (± standard...

Ovarian cancer has a poor prognosis and is difficult to detect in early stages. Therefore, developing new diagnostic markers for early-stage ovarian critical. Here, we developed marker on the basis of fatty acid metabolism characteristics cells. The expression various metabolizing enzymes such as stearoyl-CoA desaturase 1 (SCD1) was altered tissue compared with that normal tissue. Changes enzymes, particularly SCD1, tissues were found alter concentrations multiple free acids (FFA) serum. We...

The composition dependence of gravitational constant $G$ is measured at the millimeter scale to test weak equivalence principle, which may be violated short range through new Yukawa interactions such as dilaton exchange force. A torsion balance on a turning table with two identical tungsten targets surrounded by different attractor materials (copper and aluminum) used measure torque means digital measurements position sensor. Values ratios $\tilde{G}_{Al-W}/\tilde{G}_{Cu-W} -1$...
