Article Synopsis
  • Using CA125 thresholds of 70 U/ml or 35 U/ml in monitoring ovarian cancer may lead to missed relapses, prompting the need for better detection methods.
  • A study involving 162 patients found that using a CA125 level defined as 2×nadir significantly improved the sensitivity and timing of relapse detection compared to the standard threshold of 35 U/ml.
  • The findings suggest that the 2×nadir CA125 level is a more reliable early warning signal for relapse, aiding in timely imaging examinations for women with serous ovarian cancer.

We proposed an antenna pair that is applicable for mobile terminals: a type of coupling feed planar antenna that has a size of 28×6 mm2, a wide band, coupling suppression and compact size. Different from the conventional antenna design, the process of band expansion comes from a dual-band antenna pair and is based on characteristic modes theory (CMA). By observing characteristic current distributions, the optimization emphasis is placed on current sensitive parts in antenna structures, which is an effective method to create or modify resonant points for exciting band potential.

Background: Endometriosis is a common benign gynecological disease characterized by growing-functioning endometrial tissue outside the uterus. Extra-pelvic endometriosis, which accounts for approximately 12% of endometriosis, is more challenging to diagnose because of its distance from the pelvic organs. Halban's theory of benign metastasis indicates that endometrial cells can appear in extra-pelvic organs via lymphatic and blood vessels, but endometrial lymph node metastasis cases are still rare.
