[Concentration Levels and Potential Ecological Risks of Current Use Pesticides in the Surface Seawater of Typical Liaoning Sea Areas].

Fourteen current-use pesticides (CUPs) in the surface seawaters of the typical Liaoning sea areas were analyzed using HPLC-MS/MS. The concentrations, distribution, and ecological risks were studied, as well as their source appointments using principal component analysis (PCA). The results revealed that seven types of CUPs were detected in the surface seawaters of the typical Liaoning sea areas.

[Occurrence and Gas-particle Partitioning of Polycyclic Aromatic Hydrocarbons in the Air of Liaodong Bay].

The gas-and particle-phase polycyclic aromatic hydrocarbons (PAHs) were collected from the air of Liaodong Bay in May and August to investigate their occurrence and gas/particle distribution. The 24 PAHs were analyzed for gas-and particle-phase samples, and the concentrations of total gas-and particle-phase PAHs were found to be 28.8 ng·m and 24.

Alisertib Induces Cell Cycle Arrest, Apoptosis, Autophagy and Suppresses EMT in HT29 and Caco-2 Cells.

Colorectal cancer (CRC) is one of the most common malignancies worldwide with substantial mortality and morbidity. Alisertib (ALS) is a selective Aurora kinase A (AURKA) inhibitor with unclear effect and molecular interactome on CRC. This study aimed to evaluate the molecular interactome and anticancer effect of ALS and explore the underlying mechanisms in HT29 and Caco-2 cells.

[Laparoscopic anterior resection of rectal carcinoma with preservation of the left colonic artery].

Objective: To evaluate the feasibility and efficacy of laparoscopic anterior resection of rectal carcinoma with preservation of the left colonic artery.

Methods: From February 2006 to February 2009, 52 patients with rectal carcinoma formerly scheduled for Dixon operation (clinical stage I and II) received laparoscopic Dixon surgery. The inferior mesenteric artery, left colonic artery, sigmoid artery or superior rectal artery, and lymph nodes were dissected through the vasa vasorum approach.
