Article Synopsis
- A new study aimed to create a standardized reporting system for bone and soft tissue tumor cytopathology, modifying an existing classification from the Milan System and comparing it to the upcoming WHO system.
- The analysis of 285 cytology cases revealed a variety of categories, with malignancy risk ranging significantly across different classifications, including a high 100% in malignant cases.
- The modified Milan and WHO systems showed high diagnostic reliability and effectiveness in identifying malignancy, suggesting they could be valuable tools for cytopathologic assessments.
The effect of combined use of alkaline electrolyzed water （AlEW） on the reduction of heat resistance of bacterial spores by high hydrostatic pressure processing（ HPP） was investigated in this study. No reduction of heat resistance of bacterial spores, which was defined as the spore survival by heat treatment at 80℃ for 15 min, was observed by the treatment of single HPP with 30MPa at 50℃ even for 6 hours. However, a 3-log decrease in the viable bacterial spores was obtained by the combination of AlEW pretreatment with 1 hour of HPP treatment.

Materials And Methods: We analyzed 98 imprint specimens and 53 ascites specimens from 98 ovarian carcinoma cases [28 CCCs, 37 serous carcinomas (SCs), 22 endometrioid carcinomas (ECs), and 11 mucinous carcinomas (MCs)]. We examined (1) frequency of intranuclear inclusion-positive cases of each ovarian carcinoma subtype, using imprint specimens, (2) frequency of intranuclear inclusion-positive cells of each ovarian carcinoma subtype, using imprint specimens, (3) frequency of intranuclear inclusion-positive cases of each ovarian carcinoma subtype, using ascites specimens, and (4) sensitivity and specificity of the presence of intranuclear inclusions for the cytological diagnosis of CCC.
