Evaluation of depth of dislocation visibility in SEM electron channeling contrast imaging in Ti-6Al-4V alloy using serial sectioning method.

In this study, we conducted a quantitative evaluation of dislocation density by scanning electron microscopy electron channeling contrast imaging for α grains of a Ti-6Al-4V alloy deformed at room temperature. The depth of visibility of dislocations is experimentally measured as 140 to 160 nm by a serial sectioning observation. This result is compared with the theoretical value and applied to evaluate dislocation density.

Safety and efficacy of neoadjuvant chemotherapy containing bevacizumab and interval debulking surgery for advanced epithelial ovarian cancer: A feasibility study.

Background And Objectives: The optimum treatment strategy for patients with unresectable advanced epithelial ovarian cancer is controversial. This study examined bevacizumab combined with neoadjuvant chemotherapy (NAC; paclitaxel plus carboplatin), followed by interval debulking surgery (IDS), for these patients.

Methods: In a prospective nonrandomized study, newly diagnosed patients received four cycles of NAC (three cycles combined with bevacizumab), followed by IDS.

Platinum-resistant recurrent ovarian cancer with long survival on bevacizumab and gemcitabine.

Platinum-resistant recurrent ovarian cancer has a poor prognosis, but combined therapy with bevacizumab and anticancer agents may be useful. We report a patient with long-term disease control by the combination of bevacizumab and gemcitabine (BEV + GEM). The patient was a 77-year-old woman with high-grade Stage IIIC serous ovarian carcinoma.

Multicenter Clinicopathological Study of High-Grade Serous Carcinoma Presenting as Primary Peritoneal Carcinoma.

Objective: We conducted a multicenter clinicopathological study to characterize patients with high-grade serous carcinoma presenting as primary peritoneal carcinoma (clinical PPC).

Methods: At 9 sites in Japan, patients with clinical PPC diagnosed according to Gynecologic Oncology Group criteria were enrolled retrospectively. The Gynecologic Oncology Group criteria allow for minor ovarian involvement by high-grade serous carcinoma.

Spontaneously Ruptured Paraovarian Tumor of Borderline Malignancy with Extremely Elevated Serum Carbohydrate Antigen 125 (CA125) Levels: A Comparison of the Imaging and Pathological Features.

BACKGROUND Paraovarian cysts are common and are generally benign; however, they are frequently misdiagnosed as being of ovarian origin. Conversely, paraovarian tumors of borderline malignancy are extremely rare. Especially, no cases of spontaneous rupture have been reported, and all previous reports had normal serum carbohydrate antigen (CA) 125 level.
