Primary Ovarian Small Cell Carcinoma of Pulmonary Type: Analysis of 6 Cases and Review of 31 Cases in the Literatures.

Objective Primary ovarian small cell carcinoma of pulmonary type (SCCOPT) is a rare ovarian tumor with a poor prognosis. The platinum-based chemotherapy is the standard treatment. However, there is little research on the clinical characteristics of SCCOPT and the potential benefits of other treatments due to its low incidence.

Wnt5a Plays Controversial Roles in Cancer Progression.

Wnt5a is a representative Wnt ligand that regulates multiple cellular functions through the Wnt5a non-classical pathway. Although Wnt5a has been implicated in various pathological conditions, its role in cancer is ambiguous and might involve methyl modifications, distinct mRNA isoforms, as well as different downstream pathways. Therefore, it is an essential factor in cancers' progression (invasion, migration, proliferation, and epithelial-mesenchymal transition), and a potential biomarker for prognosis and treatment.

[Pilot Study on Start-up and Stable Operation at Low Temperature Based on Denitrifying Phosphorus Removal].

In order to understand the denitrifying and phosphorus removal characteristics of denitrifying phosphate-accumulating organisms (DPAOs), a pilot scale (20 m) denitrifying and phosphorus removal experiment was carried out using a modified University of Cape Town (UCT) process at low temperatures of (6-16)℃. The test results show that at such temperatures, the hydraulic retention time (HRT) is 20 h and the solids retention time (SRT) is 35 days, and the modified UCT process can start up successfully and run steadily. When running steadily, the system can maintain nitrogen and phosphorus removal rates of 60%±5% and 80%±5%, respectively.
